PREFACE. 


SiXT£ZK  editions  of  this  work  have,  it  is  hoped,  sufficiently 
stamped  it  as  a  favourite  of  the  public.  In  undertaking  the 
seventeenth,  with  which  he  has  been  entrusted  by  the  proprietors, 
the  Editor  feels  that  he  can  best  carry  out  the  wishes  of  the 
late  respected  Author  by  endeavouring  to  effect  what  improve- 
ments in  it  he  is  capable  of  doing,  and  such  as  the  advanced 
and  advancing  state  of  the  science  on  which  it  treats  appears 
to  demand. 

It  will  be  seen  that  the  work,  which  has  hitherto  been  pub- 
lished in  three  volumes,  is  now  embodied  in  one.  In  accom- 
plishing this,  consider^le  alterations  were  necessarily  required. 
Much  superfluous  matter  has  been  removed ;  and  in  arranging 
the  work  more  systematically,  it  has  been  in  many  instances 
found  necessary  to  re-write  subjects  entirely,  as  the  more  con- 
venient method  of  incorporaling  the  Author's  ideas  with  the 
desired  improvements.  Besides  this,  many  articles  altogetJier 
new  have  been  supplied,  which  it  is  hoped  will  add  both  to  the 
interest  and  value  of  the  work. 

The  engravings,  fifty-six  in  number,  by  Mr.  Branston,  are 
entirely  new,  and  most  of  them  are  on  new  subjects. 

In  eflecting  these  alterations  and  intended  improvements,  the 
original  plan  has  yet  been  preserved ;  for  although  the  work  has 
been  much  extended,  it  still  gives  a  general  and  popular  outline 
of  the  structure  of  the  horse,  and  a  compendium  of  the  diseases 
to  which  be  is  liable. 

In  former  Prefaces  the  Author  has  reviewed  in  some  measure 
the  productions  of  our  Euithors  in  this  country,  as  well  as  on 
the  Continent.  Veterinary  works  being  now  however  too 
numerous  to  permit  us  to  follow  out  this  plan  to  the  same  ex- 
tent, a  glance  at  them  must  suffice. 

France  has  furnished  a  considerable  addition  to  our  veterinary

Profeasor  Gvlk  has  lately  produced  a  valuable  work  on  Oaltlo 
Patliology. 

To  llieae  we  may  add  the  writings  of  Vatc!,  Renault,  Orognier, 
Moirond,  Dopoy,  Bernard,  and  Bouti-y,  bi-sidea  two  veterinary 
periodical^:,  which  arc  carried  on  with  »0")e  spirit.  Professor 
Gurit,  of  Berlin,  lti»  |nibti»hed  some  excellent  plates  of  tlie 
anatomy  of  llie  hone  and  otlier  animals,  which,  with  those  of 
Miiller,  evince  much  accuriicy  and  rt^earcli ;  and  Professor 
Delwari,  of  Brusiels,  lias  presented  the  public  with  a  useful 
pathological  work. 

In  this  country,  although  our  authors  have  not  been  quite  so 
prolific,  ihey  have  not  been  less  woriJiy  »i'  upprt^tion.  Fint 
and  foremost  we  must  notice  the  works  of  Mr.  Percivall,  who 
some  years  since  presented  ua  with  three  volumes  of  lectures^ 
cmbruring  llie  greater  ]>art  of  ihc  anatomy  and  physiology,  and 
extending  itself  to  much  of  l)ie  palholog)-  of  the  horw;:  and 
more  recently  they  have  been  followed  by  a  work  on  the  anatomy 
of  tile  liorse,  which  for  correcincss  and  comprehensiveness  has  not 
been  surpaesedL  This  work  has  been  succeeded  by  two  vi^umes 
styled  Hip|M>p<(thnl(yy,  hoili  of  which  justly  hold  a  foremost 
rank  in  our  veterinary  literature. 

Mr.  Bracy  Clark  has  from  time  lo  time  presented  us  with 
elaborate  treaiisea  on  various  Kubjects,  such  as  the  I-'oot,  SItoeinp, 
Worms,  &c.  i  mill,  lately,  on  the  \'ic«s  of  Horses.  They  all 
display  much  talent,  and  develo[>e  cotitidprabl«  learning  and 
ingenuity. 

Mr.  liiaine's  work,  botit  on  tlte  Horse  and  th«  Dog.  have 
gone  through  several  editions,  each  of  which  evinrvs  coiiMtlei*- 
ab)e  and  progrMsive  improvement.  This  f^enileman  lia«  re- 
cently coniplelcd  a  work,  entillttl  "An  Kncyclopivdia  of  Sport-

PREFACE 

TO  THE  THIRTEENTH  EDITION. 


About  two  years  only  have  elapsed  since  the  twelfth  edition  of 
this  small  volume  was  published:  such  kind  encouragement 
cannot  fail  of  increasing  the  author's  ardour  and  industry  in  the 
cultivation  of  his  profession ;  and  he  trusts,  by  continued  and 
zealous  attention  to  veterinary  practice,  to  make  still  further 
improvements  beyond  those  he  has  now  to  offer.  In  the  last 
edition,  I  gave  some  account  of  veterinary  writers,  especially 
those  of  the  French  nation.  1  have  now  to  pay  some  tribute  of 
respect  to  the  memory  of  those  of  our  own  country,  who  have 
written  many  works  of  great  utility,  though  not  what  are  consi- 
dered scientific  performances ;  as  well  as  a  short  account  of  the 
works  of  living  veterinary  authors. 

The  earliest  English  writer  on  Farriery  we  have  an  account 
0^  ia  Mascal,  who  lived  in  the  reign  of  Edward  the  Sixth.  He 
published  a  treatise  on  Farriery,  which  was  greatly  esteemed, 
and  passed  through  several  editions.  At  the  same  time  lived 
Martin  Clifford,  who  also  wrote  a  treatise  on  Farriery ;  but  it 
was  not  considered  of  any  value,  and  passed  through  two 
editions  only.  Next  to  him  appeared  Captain  Burdon,  of  the 
Dragoons,  who  published  a  very  small  treatise  on  Farriery, 
which  was  universally  read  and  esteemed  in  the  reign  of  Queen 
Elizabeth.  This  small  work  was  republished,  with  notes,  by 
Dr.  Bracken.  Three  years  after  appeared  Gervase  Markham, 
the  most  renowned  of  ancient  farriers.  He  published  a  work 
under  the  name  of"  Markham's  Masterpiece,"  in  the  year  1666 ; 
it  passed  through  twenty-five  editions,  the  last  of  which  appeared 
in  1729.  He  was  in  practice  more  than  sixty  years.  In  the 
year  1740,  De  Grey  published  his  "Compilation  on  Farriery," 
which  was  not  much  esteemed.  Snape,  farrier  to  King  Charles 
the  Second,  published  the  6r8t  English  treatise  on  the  An.itomy 
of  the  Horse;  but  it  was  taken  in  great  measure  from  Ruini, 
an  old  Italian  author  of  great  merit.  In  the  year  1770,  Sir 
William  Hope  published  a  translation  of  Solleysel's  work,  which 
was  much  read  and  esteemed.  In  the  reign  of  King  George 
the  First,  Dr.  Layard  published  an  Account  of  a  dreadful  Epi-

demic  which  raged  amonc  Csttle.  Other  piiblicaiiotn  of  a 
rftimilar  nature  appeared  about  the  same  time.  In  ilie  year 
'  1750,  appeared  the  best  book  on  I'arriery  that  bad  ever  been 
written,  by  William  Gibson,  a  surgeon.  It  went  through  many 
ediiiom,  and  is  sliU  considered  vuhiable.  Alwut  the  same  time 
Dr.  Bracken  publiitlit.-d  two  volume*  on  Tarriery,  which  n-ero 
sreally  etteemed,  nnd  are  ttill  reiul.  DnrtletiV  "Giiitletnan's 
f  Complete  Farrier"  next  jippearfd.  He  published  tiUo  a  Veieri- 
1  nary  Pharniacopt»-ia.  The  Ibiuier  was  in  great  meuaiin-  un 
abridgment  of"  (iil)son.  It  contained,  however,  a  new  metliod 
of  nicking,  and  a  description  of  Lalbsse's  supposed  cure  for  the 
glanders.  Osmer  next  published  a  treatise  on  Lameness,  con- 
taining many  new  and  useful  observations ;  also,  a  "  Description 
and  liecommendatiou  of  Lafossc's  Half- Moon  Shoe"  ^  a  stioe 
thtil  I  do  not  consider  proper  on  any  occasion  whatever ;  be-

the  toe  is  growing,  wliioli  muat  be  »  gn-iit  injury  to  tlic  Hcxor 
tendon,  or  ib  appendages,  and  caum-  the  frog  10  n-ceive  moro 
pressure  than  it  was  designed  for.  He  after wni-d.t  wrote  a  book 
on  an  epidemic  disease  that  prevailed,  which  contained  iminy 
useful  observations.  In  tlie  year  1780,  Mr.  James  Clark,  of 
Edinburgh,  published  a  small  work  "  on  the  Pnevention  of 
Disease  by  Exercise,  Feeding,  Bleeding,  &C,"  This  is  an  excel- 
lent work,  and  may  Ijc  still  n-ad  with  itdvantage  by  veterinary 
sdident.*.  I^itl  Pembroke,  about  this  lime,  published  a  wofK 
on  Mursem^inihip,  which  contained  many  sensible  observation* 
nn  tile  dixentcs  of  horses  and  on  shoeing.  His  lordship  was 
Colonel  of  the  VinU  or  Koyal  Dragoons,  and  had  ihe  horses  of 
liis  regiment  titovti  according;  to  a  plan  of  hi^  own.  This  plan 
wa*  continual  while  1  wii»  in  the  reginicnt,  and  is,  I  believe, 
xtill  in  use.  This  shoe  is  ttiat  which  I  now  ri^conimeiid  for  good 
feet  About  die  year  1789.  Mr.  Taplin's  "Stable  Dirx-clory" 
appeared :  a  book  that  was  much  reau,  and  passed  tlirough  many 
edition*  in  a  few  yvan.  A  «uppler)ientary  volume  was  afiei^ 
wanls  published,  and  a  small  painpblel,  named,  not  very  justly, 
"  Multum  in  Parvo,"

this  time  two  octavo  volumes  were publislted,  entitled, "  A  Philo- 
Mphical  Treatise  on  >Iorses,"  by  Mr.  John  Lawrence.  The  first 
volume  merits  particular  notice:  it  contained  a  forcible  appeul 
to  the  feeling  of  the  public  in  support  of  (ho  rights  vf  korua^ 
and  ought  to  be  read  by  all  horse  proprietors,  "the  other  con- 
tained much  useful  practical  information;  but,  as  Mr.  Lawrence 
was  not  a  regular  student  of  the  veterinarv  profession,  it  of 
course  contained  some  errors,  and  is  vsluahte  chiefly  as  a  com- 
pilation. In  the  year  18(li,  Mr.  Iticluird  Lawrence  publislied  a 
quarto  volume  on  some  of  the  (liwuR-s  of  ilic  horse,  with  some 
useful  and  accurate  plates.  This  is  a  work  of  considerable

tliat  has  been  attempte<l  in  this  countrv  ;  and,  notwithstanding 
the  severe  remark  of  Frofesaor  Girarcl  and  M.  (jauze  on  it,  1 
think  the  work  much  more  valuable  than  that  of  tlie  latter 
author,  although  his  large  quarto  contains  more  than  a  hundred 

Elale« :  and  of  <?<iual  value  to  M.  Girard's  works,  not  excepting 
is  "TraitOdu  ricd."  About  this  time  appeared  a  book  by 
Downing,  and  anoltK-r  by  Tophain,  on  ihe  Diseases  of  Cattle.

clear  point  of  view  the  indiijK usable  necessity  of  anatomical  and 
physiological  knowledge  to  the  veterinary  pntctitioner.  Several 
works  were  published  liy  Bmirgclat  on  veterinary  subjects,  which 
are  still  held  in  considerable  c-ilim.ition  :  the  principal  are, — "  A

waa  published  by  the  same  author,  in  4  vol^  t^vo.     This  work 
contains   much  useful    inlornintion.    In  1771    Vitet's   "  Vete-

sted  efficacy  of  this  mode  of  irealment,  it  appears  from   a 

but  publication  on  glanders,  by  M.  DiipnVi  that  it  has  been 

fairly  tried  at  (l>e  Veterinarv  School  at  Alfori,  and  has  not  in  a

France  siiKe  llie  Revolution  is  A  'I'reatise  on  the  Anatomy  of 

Domt^ttc  Animals,  by  Professor  Girard,  IS07,  two  volumes  8vo, 

In    1813,  tliere  a])peared  A  Treatise  on  the   Feet,  &C.,  by  the 

same  author,  in  one  volume,  Bvo.,  with  six  plates  illustrative  of 

the  aniilomy  of  the  foot,  not  only  of  the  hone,  but  of  the  oiber

under  the  title  of"  CouraTJi^oriqneet  Pratique  de  Mar^lialerie 

Veterinaire,  par  F.  Jau-te."    This  work  was  conipleled  in  1818, 

and  forms  one  large  4to  volume,  with  no  less  than  110  plates. 

M.  Jauxv  announces  another  work  us  about  to  be  published  in 

five  volumes  Hvo.,  with  uumeron*  pliiies.     This  work  is  said  to 

treat  of  ilie  internal  and  external  pathology  of  the  larger  do- 

tnestjc  animals,  the  velerinaiy  Materia  Mediea,  and  the  vot^ 

rinary  jurisprudence.     "  Every  article   in   this   treatise,"  the 

author  says,  "  will  be  described  with  particnlar  order  and  pre-

and  medical  juriBprudence  are  delivered  at  this  school,  in  ad- 
dition to  those  given  at  Lyons.  Stallions  are  kept  at  the  ex- 
pense of  government,  and  sent  annually  into  the  provinces  to 
improve  the  breed  of  horses  ;  asues  are  also  sent  far  tlie  purpose 
of  producing  mules,  which  are  much  used  in  some  of  the  pro- 
vinces. The  infirmaries  for  horses  and  the  otiier  domestic 
animals  are  more  extensive,  and  better  arranged  than  those  at 
Lyons;  and  the  forge  affords  more  convenience  for  giving  in- 
structions in  shoeing :  there  is  also  a  portable  forge,  which  may 
be  removed  to  any  part  of  the  stables  where  its  use  is  required. 
A  6eld  of  about  six  acres  is  set  apart  for  agricultural  expe- 
riments. The  royal  stables  at  Paris  are  well  constructed  build- 
ings —  well  paved,  drained,  and  ventilated :  the  horses  do  not 
stand  on  litter  during  the  day.  They  appear  capable  of  con- 
taining about  two  hundred  horses.  An  infirmary  and  forge  are 
attached  to  the  stables.  All  the  royal  siud,  as  well  as  the 
cavalry  horses,  are  shoed  upon  the  plan  established  by  the  veteri- 
nary schools,  under  the  superinten dance  of  a  resident  veterinary 
sui^eon. 

The  following  year  Mr.  Sewell  visited  the  veterinary  schools 
in  Germany;  and,  on  his  return,  made  a  report  of^  his  ob- 
servations  to  the  governors  of  the  London  Veterinary  College, 
of  which  the  following -is  an  extract :  —  Tlie  Veterinary  School 
at  Vienna  is  inferior  to  that  at  Alfort;  but  it  affords  a  greater 
scope  for  practice,  the  stables  and  other  accommudaiiuns  being 
calculated  for  receiving  a  considerable  number  of  patients;  all 
of  them  were  then  occupied,  which  afforded  Mr.  Sewell  an  op- 
portunity of  seeing  some  diseases  peculiar  to  the  season  which 
was  very  hot  and  dry ;  the  principal  of  these  were  lameness, 
called  fever  in  the  feet,  and  lethargic  attacks.  The  lameness 
was  treated  as  it  is  in  this  country,  with  the  addition  of  turning 
the  patient  into  a  paddock,  where  the  grass  was  high,  kept 
watered,  and  well  shaded  with  trees.  The  horses  with  lethar^ 
were  also  kept  in  the  paddock  under  the  trees,  and  their  heads 
were  often  placed  under  a  shower  bath.  From  the  number  of 
those  that  were  in  a  convalescent  state,  Mr.  Sewell  concludes  that 
the  treatment  was  successful ;  though  he  says,  it  does  not  accord 
with  the  theory  or  treatment  of  the  disease  taught  in  this  coun- 
try. They  consider  the  lethargic  symptoms  as  dependant  on 
some  disorder  of  the  digestive  organs  and  liver,  and  treat  It 
accordingly.  The  pupils  are  taught  shoeing  practically  at  the 
forge.  The  shoes  are  different  from  our  own  acid  those  of 
France.*     The  stables  are  not  of  the  first  order,  but  roomy  and 

■  According  to  M.  Jauze,  "  the  Oerman  shoes  are,  of  all  othera,  the  most 
injurious  for  horses  that  have  sound  feet.  There  are  three  lurge  crninpoiia 
(caulking)  ;  one  at  the  toe  and  at  each  hee),  which  make  the  shoe  very  he.tvy.

structed,  paved,  atid  ventilated;  the  box  stalls,  and  placps  for 
other  domestic  animals,  are  well  arranged.  Litter  is  not  tised 
during  the  day,  but  sand  is  strewed  under  the  horses.  The 
stables  were  full  of  patients  of  all  descriptions:  there  were 
several  cases  of  lameness  and  lethargy  similar  to  those  at 
Vienna,  and  their  treatment  was  nearly  the  same.  There  was  a 
case  of  locked  jaw  that  had  been  cured  by  a  method  diflerent 
from  that  employed  in  this  country.*  A  riding  house  is  at- 
tached to  the  school,  for  the  instruction  of  pupils  intended  for 
the  army ;  who  receive  pay  from  the  time  of  entrance.  There 
is  a  beautifully  constructed  warm  water  and  vapour  bath,  with  a 
room  adjoining,  to  receive  the  patients  after  bathing,  which  is 
heated  occasionally  by  a  stove ;  the  bath  is  supplied  with  hot  or 
cold,  water  by  an  ingenious  hydraulic  contrivance.  The  royal 
stables  are  handsome  buildings,  and  kept  in  excellent  order. 
Sand  is  used  under  the  horses  instead  of  litter  in  the  day  time. 
They  adjoin  the  river  Spree,  into  which  there  is  a  paved  slope, 
which  enables  them  to  bathe  or  wash  their  horses.  Mr.  Sewell 
brought  with  him  some  useful  instruments  for  relieving  oxen  or 
sheep  that  are  hoven  or  bloKJt ;  he  has,  since  his  return,  sent  them 
into  the  country  for  trial ;  they  are  said  to  be  employed,  with 
great  success,  in  Germany, 

On  arriving  at  Hanover,  Mr.  Sewell  was  introduced  to  Pro- 
fessor Havemann  by  assistant  Professor  Houscmann,  whom  he 
had  seen  in  England.  The  infirmary  stables  had  much  dila- 
pidated during  the  war,  from  being  occupied  by  foreign  cavalry. 
There  were  no  patients  in  them.  The  royal  stables  which  will 
contain  between  two  and  three  hundred  horses,  are  near  the 
school ;  they  are  handsome  buildings,  well  constructed,  light, 
airy  and  spacious;  the  windows  have  canvass  shades. 

In  Holland  there  are  no  veterinary  schools.  The  royal 
stables  at  the  Hague  are  well  constructed,  and  in  fine  order. 
The  heads  of  the  stalls  and  bottoms  of  the  mangers  are  lined 
with  glazed  Dutch  tile,  and  are  kept  in  the  cleanest  slate,  with 
very  little  trouble.  Sand  is  used  in  the  stalls  in  the  day  time. 
At  Brussels,  there  was  nothing  worthy  of  attention,  except  an 
effeclual  method  of  draining  a  large  barrack  stable,  which  Mr. 
Sewell  does  not  describe.  He  says,  that  by  inquiries  and  oh- 
serration,  he  obtained  in  Holland  some  vsefiil  practical  inform-

proTcineiiu  he  may  liavfl  obsen-ed  in  the  practice  of  lite  veie- 
rinary  art,  lie  will,  no  doubt,  communicate  lo  the  public. 

It  is  difficult,  perhaps  impossible,  to  form  a  correct  com- 
parative estimate  of  the  state  of  veterinary  wii'nrv  in  this  country 
and  France,  merely  by  perusing  the  work*  of  tlie  I'rwich  pro- 
fessors and  veterinary  practitioners;  but  if  one  might  prv--<unic 
to  judge  from  such  evidence,  the  niiihor  would  feel  no  hesitation 
in  saynij^,  that  he  ihinkn  the  veterinarv  art  liaa  made  greater 
progren  in  Kiiglatid  tliun  in  France.  In  ihe  latter  countryt  it 
was  cultivated  by  men  of  science,  at  an  early  period ;  but  here, 
it  can  scarcely  be  said  to  have  existed  till  tlic  establishment  of 
the  Veterinarv  College.  Some  good  ])ntctical  works  appeared 
before  that  lime,  particularly  Gibson'K  and  Clarke's;  but  tl»e 
anatomy  and  physiology  of  the  hoi-se  had  not  been  attended  to. 
Since  ilutt  pei-iod,  however,  it  has  l>eenasaiduouily  mudied;  atid 
to  (he  acquisition  of  tliti  t-s^ntial  branch  of  knowledge  we  may 
aiiribulc  the  great  improvement  (liat  has  been  made  in  tlte 
treatment  of  diseases.  French  practitioners  appear  lo  be  aitll 
influenced  by  the  humoral  puihulogy,  as  it  is  termed,  and,  con- 
soipii-nily,  dqii-nd  too  mtieh  on  ilceoctions  of  plants,  aiid  other 
vegt'iiible  pr('{>ar:itionx,  in  aciilt!  di*eit«.-s,  many  of  which  arc 
nearly,  if  not  ()uite,  inert,  with  respect  to  the  Iioi'ie;  white 
similar  diseases  in  ttiis  counti;)'  are  often  subdued  by  one  copious 
bleeding.  Much  praise,  however,  is  due  to  tlin  veterinary  prac- 
titioners of  France  for  the  great  attention  ihey  appear  to  pav  to 
morbid  anatomy.  The  accuracy  and  niinuleue»  with  wfiich 
morbid  Bubjects  are  examined  after  death,  and  the  scrupulous 
attention  with  which  every  symptom  of  a  dis<-ase  is  observed  and 
noted,  i#  nonhy  the  imitation  of  British  practitioners.

PART  I. 

THE   ECONOHT    OF   THE    STABLE. 


INTRODUCTION. 


As  the  preservation  of  the  horse's  health  ia  an  ohject  of  the  high- 
est importance,  I  shall  begin  my  treatise  with  some  observations 
on  that  subject.  The  most  effectual  method  of  accomplishing  this 
is  to  keep  him  in  a  wholesome  stable,  work  him  fairly,  feed  him 
properly,  and  to  observe  all  those  attentions  which,  taken  toge- 
ther, and  considered  generally,  are  named  grooming.  Accord- 
ing to  this  view  of  the  subject,  the  first  object  of  consideration  ia 
the  coiutruction  and  arrangement  of  the  stable. 


CHAPTER  I. 

OH     THE     STABLE. 


LoFTiHEBS  is  very  desirable  in  a  stable.  It  should  never  be  less 
than  twelve  feet  high,  which  will  admit  of  its  being  properly 
ventilated,  without  tne  necessity  of  currents  of  cold  air.  The  air, 
by  being  breathed,  becomes  unfit  for  the  purpose  i^in,  having 
undergone  a  change  in  its  constituent  principles.  This  change 
consists  in  the  deprivation  of  a  portion  of  its  oxygen,  which  ia 
essential  for  the  purpose  of  life,  and  the  subsUtution  in  its  stead 
of  carbonic  acid  gas,  the  inhalation  of  which  would  quickly 
deprive  an  animal  of  existence.  Fortunately  the  respired  air, 
from  being  heated,  quickly  ascends,  whilst  a  supply  of  fresh 
air  enters  the  noetrila.  The  foul  air,  from  this  circumstance,  does 
not  enter  the  lungs  again,  unless  the  pure  air  of  the  stable  be 
exhausted)  or  so  diminished  as  to  become  mixed  with  tliat  pre- 
viously expired.     Thus  the  partial  deprivation  of  oxygen   is

sliouid,  lliercrorc,  be  coiistructcd  to  sdmit  boll)  lliosc  purpose's— 
in  the  summer  lo  admit  as  much  cool  nir  as  possible,  and  in  the 
winter  sufficient  for  the  purpose  of  purity,  without  rendering  the 
Blablc  too  cold,  or  ocaiHioiiinj;  «lmught».  It  follown,  hawrvcr,  tliAt 
if  wu  ciiti  ensure  our  end  in  cold  weather,  we  nni  readily  do  so 
in  hoi  H'eiither,  by  mcAus  of  the  doors  and  uinduws.  The 
heated  foul  air  may  be  allowed  to  escape  by  means  of  a  chimney, 
or  square  opening  in  the  ceiling,  communicating  with  the  open 
air,  or  it  may  be  made  in  the  form  of  a  dome  or  ctijwlo,  whidi 
would  be  more  ornamental.  'Ilie  chimney  iictftl  not  be  ofwn  at 
tlie  top,  io  lu  to  admit  ihe  iiiin,  but  should  be  roofed,  ami  have 
lateral  openings  by  means  of  weather-boards,  as  they  are  termed. 
A  still  i>eller  plan  is,  by  having  smaller  ojienings  over  eacit 
stall,  any  of  which  may  be  closed  when  the  horse  is  absent.  The 
admiMiun  of  pure  nir  ih  likewino  lu  W  provided  for  :  if  allovrcd 
to  come  in  at  the  windows,  there  will  be  »  grrat  druiigltt  on  tlie 
horse's  hind  ijuariers,  where  il  is  least  rec|uired.  The  liest  plan 
is  lo  admit  it  towards  the  animal's  head,  by  means  of  a  pijie  or 
wo(Kk-n  box  having  a  number  of  perforations,  so  that  ihere  maj' 
!»'  no  sudden  draught  in  any  <tircclion.  Cold  air  should  i>ol  be 
nlluned  to  enter  the  stable  door  or  near  the  horse's  tiecU,  us  this 
it  very   likely  to  produw  gn-ose,  or  chapped  hcik  —  Kl>.] 

A  Riable,  when  projierly  pave<l,  and  kept  moderately  rle«n,  re- 
quires only  a  sliallow  wide  gutter,  twelve  inches  wide,  and  one 
inch  deep.  The  best  floor  for  a  stable,  by  fur,  is  bard  brick ; 
nnd,  next  to  that,  linicstonc,  not  li-ss  ihnn  one  fool  square.  I 
havoMX-n  astabte  belonging  lo  Mr.  I.ovell  of  Wells,  that  is  ihit* 
pAvcd,  but  with  wider  stones,  and  so  chipped  ii«  to  luive  numc- 
i'ou§  small  furrows,  all  of  them  tending  towards  the  centre  and 
buck  part,  and  I  never  JK-fore  saw  bo  clean  or  8o  nice  a  stAblt% 
except  one  txrlonglng  to  Mr.  Atkinson,  at  Cheddingion,  and  iImU, 
I  think,  was  Miperior  to  any  I  ever  met  with,  esiiecially  in  iu 
interfor  arrangement  The  floor  of  the  stall  shoiihl  newr  iiieliiie 
more  tlian  one  inch  in  a  yard,  und  the  inclinnlion  thould  bccon- 
Itnued  back  to  the  gutter  only.  Some  litter  aJiould  alwayi  be 
aIIowmI  for  a  horse  to  sinle  upon,  which  should  l>e  swept  away 
IU  often  as  in  ncce«s<iry.  This,  with  a  pallor  two  of  water  thrown 
upon  iIh*  floor,  wid  swept  off  wliiie  the  hor»e  is  ai  exercise,  will 
keep  the  stable  perfectly  elcxn,  and  free  fi-om  offensive  smelb.

horses ;  that  is,  to  have  two  straps,  one  uii  each  side  the  titall, 
about  one  yard  from  the  lirad  ot  it  Dy  these  the  horse  may 
be  ^tened  during  the  time  he  is  cleaned,  by  which  me«uta  he 
will  be  effectually  prevented  from  biting  the  manger  or  tlie

ferred, the  rock  slaves  should  be  straight,  and  brouglti  nearly

in  consequence  of  this  circinnstance.  ISean^,  wl»en  broken  or 
bruised,  may  be  an  iifcfiil  article  of  diet,  joined  with  oais,  for 
horses  whose  work  is  cotiiiaiit  and  bard.  1  have  been  assured, 
however,  by  some  experienced  coach  and  post  mnaters,  that 
during  (ho  liot  summer  montlis  it  is  better  to  discontinue  the

appetite ;  in  which  ca»c  it  is  prohable  ihcy  do  not  digest  them

of  their  corn  witltoul  chewing  it;  and  as  corn  that  is  swallowed 
unbroken  is  knovrn  to  be  indigestible;  the  bruising  of  oats  must 
be  considered  as  a  matter  of  great  importance,  and  may  be  the 
means  of  saving  a  considerable  quantity  of  that  articlo.f  Another

when  the  liay,  as  it  often  is,  is  bad,  tlie  coniteijuence  is  still  worse. 
'I1ie  stomach,  by  audi  management^  is  sure  to  become  in  time 
more  or  less  diseased;  and  when  tbia  liappens,  a  foundation  is 
lid  for  many  diseases. 

Thus,  besides  the  additional  expense  of  this  imprudent  method 

of  feeding,  many  disorders  are  cngemlcred   by  it :  and,  1  may 

aafcly  add,  that  a  horse  so  fed  will  not  do  his  work  half  so  welt 

as  one  tluit  is  fed  properly.     A  )ior«c  whose  work  consists  in 

travelling  a  ilage  of  twenty  miles  three  times  a  week,  or  twelve 

every  day,  siiould  have  one  peck  of  good  oats,  and  never  more

mended, it  may  almost  always  l»e  aocomplislied.  The  injury 
done  to  (he  stomach,  by  the  common  method  of  feeding,  and 
cons«-quontly  to  the  animal's  beatib  or  constitution,  arises  from 
the  flisicntion  of  the  stomach  witli  fooil,  and  the  larnc  bowels 
with  excrt-iintit,  which  im)K-<lcx  i-eitpjivition,  an<l  debilitates  the

performed  in  the  home,  not  only  by  a  juice  secreted  in  the 
stomach,  but  also  by  iniactilar  contractions.  When  tltc  sioinach

becomes  unhealthy  and  deficient,  aiid  is  incapable  of  convertbig

In  a  state  of  nature,  ami  even  in  his  domesticated  state,  under 
good  management,  the  horse  iuis  a  moderate  and  a  very  delicate 
Kf^tite,  and  is  very  nice  in  his  clioice,  both  of  food  and  water. 
I  have  seen  a  large  stud  of  horses  that  verv  kept  in  tho  hif^heet 
condition  on  an  allowance  of  eight  pounds  of  buy  in  the  <lny  and 
ni^ht,  nnd  five  quartern*  of  corn.  HorM's  fo  fed  will  nut  drink 
much  wutL-r,  —  jH'rhnps  from  two  to  four  gallons  in  the  day  niid 
night:  while  one  that  has  acquired  a  voracioux  and  depraved 
appetite  has  been  known  to  drink  tbiir  paiifuls  at  a  time,  tliat 
is,  from  twelve  to  sixteen  galloiu,  and  cat  from  thirty  to  forty 
pounds  of  hay  in  a  flay  and  nighl.  With  such  a  load  in  the 
stomach  and  bowels,  what  can  be  expected  but  an  abridgment 
of  the  animal's  life  and  services  lo  one  third  of  the  perioti  to 
which  they  might  lutve  been  extended  under  pro])er  manage- 
ntent?  and  his  labour  during  this  sltort  period  is  often  inter- 
rupted by  sickness. 

The  manner  in  which  liorses  arc  commonly  f«.-d  is  apt  to  de- 
prave or  vitiate  ibe  appetite,  and  probably  cause  M>nw  degree  of 
aridity  in  the  stomncli  and  bowel*.  Tfiis  is  the  only  way  in 
which  I  can  account  for  ibe  (>ro|H>ii!(ity  so  common  in  horses  to 
drink  muddy  water,  and  est  ntrth  or  dirt  of  any  kind.     Mr. 


TREATHSNT   OF    BOUSES    IN    SUMMER.  11 

Feron,  in  his  "  Treatise  on  Farriery,"  says,  "  Horses  at  camp 
are  very  apt  to  eat  earth  or  sand ; "  and  tliat  he  has  "  opened 
horses  that  have  died  from  this  cause,  and  found  nearly  two 
buckets  of  sand  in  the  large  bowels,  named  colon  and  ceecum." 
Whenever  this  propensi^  is  observed  in  a  horse,  a  small  knob 
of  clay  should  be  mixed  with  his  water ;  but  this  will  only  afibrd 
a  temporary  relief:  the  propensity  can  only  be  cured  by  a  mild 
dose  of  physic,  and  a  change  of  diet.  Though  horses  are  often 
permitted  to  indulge  this  propensity  because  the  groom  or  the 
proprietor  does  not  perceive  any  ill  effect  immediately  resulting 
from  it;  yet  it  is  always,  sooner  or  later,  productive  of  ill  conse- 
quences. It  may,  indeed,  neutralise  some  acidity  in  the  stomach 
and  bowels,  caused  by  immoderate  or  unwholesome  feeding,  and 
thereby  do  a  little  good  for  some  time;  but  then  it  is  only  pro- 
tracting a  disorder  for  a  short  time,  which  auch  feeding  is  sure, 
sooner  or  later,  to  bring  on.  Disorders  of  this  kind  may  be  very 
slow  in  their  accession  and  in  their  progress,  and  on  that  account 
may  escape  notice  for  a  considerable  time,  and  when  they  do 
^ipear  are  generally  referred  to  some  other  cause  The  same 
may  be  observed  of  disorders  produced  by  pond  water  impr^- 
nated  with  excrement. 

It  is  a  very  common  opinion  that  the  water  an  animal  prefers 
must  be  the  best  for  him:  and  were  its  appetite  consulted  when 
in  a  state  of  nature,  this  rule  might  be  safely  followed ;  but  as 
horses  are  at  present  mani^ed,  it  is  generally  necessary  to  choose 
for  them,  with  r^ard  both  to  food  and  water.

ON   THB   TREATMENT    OF    HORSES    IN    SUMMER. 

It  is  too  much  the  practice  in  turning  horses  out  in  summer 
to  choose  the  richest  pastures,  as  if  the  mtention  of  giving  them 
this  indulgence  were  to  fatten  them.  Many  inconveniences 
result  from  this  practice,  and  not  unfrequently  much  injuiy  is 
done  to  the  animal,  and  great  difficulty  found  in  getting  him 
into  working  condition  when  he  is  taken  up.  The  best  time  for 
turning  out  a  horse  is  the  latter  end  of  May,  or  b^inning  of 
June.  Hi^  land  is  better  than  meadows,  especially  such  as 
adjoin  rivers,  or  are  otherwise  wet.  Short  sweet  pasture  should 
be  chosen ;  it  is  better,  indeed,  to  have  it  rather  bare  than  abun- 
dant, and  if  there  should  not  be  sufficient,  some  hay  and  oats 
should  be  given.  If  the  nights  are  cold  he  should  be  taken  up 
at  night,  and  put  into  a  cool  airy  box,  where  he  should  also  be 
kept  during  the  day,  when  the  weather  is  very  hot  and  dry.     A

ia  a  Gtrcam  of  irater  or  a  pond  in  the  ticld,  and  l)i«  horse  hss 
been  accustomed  to  drink  immoderately,  it  should  be  fenced  olT, 
and  a  moderate  ijuantiiy  ^vcn  twice  a  day  with  a  pail.  A 
modi-rali'  quantity  of  vetches  may  be  given  with  advantage  in 
audi  a  Kitiiiitioi) ;  taking  care  not  to  give  them  m>o»  after  they 
are  cut,  or  with  the  dew  upon  (hem.  liy  keeping  a  honic  in 
this  manner  for  a  moiilh  or  »ix  weeks  in  the  situation  I  havu 
dettcribed,  he  will  receive  all  the  bene6t  to  be  ex|>ect«d  from  a 
run  at  grass,  and  avoid  llie  inconvenience  which  so  often  results 
fiom  the  method  commonly  pursued.  Another  imporlant  ad- 
vantage wi})  be  obtained  bv  il;  for  when  tlie  horse  is  taken  up 
there  will  he  no  difBcully  in  golting  him  inio  good  working 
condition  in  a  sltorl  time.  If  there  is  no  convenience  for 
managing  the  horse  as  I  hare  described,  it  will  be  better  to  soil 
him  with  v<'iclie»  or  short  sweet  grass  in  n  large  airy  box  for 
aliout  u  month,  than  to  turn  him  out  in  the  manner  gi-nerally 
praclistd.  In  soiling,  only  a  nioderatt-  i|Uiititity  of  green  fix>d 
should  be  given  at  a  time,  and  a  aniall  quajitity  of  hay  and  oats 
should  also  be  allowed. 

[The  practice  of  soiling  hunters  in  the  stable  during  the 
summer  is  strongly  advocated  by  Nimrod,  the  celebrated  sport- 
ing writer,  who  forcibly  argues,  that  tlie  preservation  of  con- 
dition, and  n  good  slate  of  the  feet,  and  other  l>em-fit«,  will  moi-e 
tlmn  repay  the  incrcawd  expt-nse.  There  can,  indeed,  be  no 
doubt  that  the  condition  of  the  litiniirr  is  better  prcM-rvcd  in  the 
wintt^r  by  not  allowing  it  to  bu  lo:<t  in  the  summer;  nnd  it  is 
easier  by  this  nu'thod  to  get  a  fine  silky  coat  in  the  former 
season.  Tho  only  objection  to  Nimrod's  system  is  the  increased 
cxi>eusc  incurred;  iu adoption  most,  therefore,  in  great  measure, 
depend  on  tlie  vulue  of  the  animal. — Ed.J

ExRticisE  must  be  considered  under  two  heads:  first,  that 
which  is  ncci-nsary  to  preserve  the  horse  in  health,  and  make 
him  capable  of  ordinary  exertions,  or  moderate  work:  secondly, 
that  which  makes  him  capable  of  extraordinary  exertions,  euch 
as  bunting  or  racing,  bxereise  of  the  last  kind  is  commonly 
named  (raining,  which  teim,  however,  includes  also  the  mode  of 
feeding  necessary  to  raise  the  muscular  power  to  thv  highesi 
degree  it  is  capable  of  altninmg.  The  horse  was  evidently  de-

elongated,  the  back  sinews  are  often  Birained ;  the  loot  becomes 
hot  and  inflamed,  its  homy  covering  contmcu ;  the  Irogs  be- 
come rotten,  and  incapable  of  performing  the  office  for  which 
ihey  were  ditigiii-d;  in  xhort,  llic  wtiolc  body  becomes  diseased.

His  powers,  however,  are  limited,  and  so  should  his  exertions 
be :  but  it  is  a  &ct,  which  must  be  regretted  by  all  considerate 
petBons.  lliat  tlie  immoderate  work  in  which  he  is  often  em- 
ployed, so  far  from  being  fslutary,  or  proportionate  to  his 
strength,  as  undoubtedly  it  was  dcsij^in-d  by  his  Creator  that  it 
stioiild  l>e,  is  injurioiiis  and  even  diTlruciive  tn  a  very  consider- 
able decree.  And  what  greatly  aggravates  the  mischief  is,  the 
early  and  premature  age  at  which  he  is  commonly  employed. 

When  a  horse  is  brougtit  in  for  training,  after  liaving  been 
kept  in  the  manner  de>cribed  in  the  preceding  chapter,  he 
should  be  fed  with  hjiy  and  oats ;  and  if  greedy  of  water  or  haVi 
or  if  he  appears  inclined  to  cat  his  litter,  he  should  be  limited  in 
hay  and  water,  and  be  muzzled  the  lost  thing  at  night.  For 
the  first  week  he  should  have  walking  and  gentle  trotting  ex- 
erciae  for  an  hour  or  two  every  morning.  'Iiie  stable  should  l>e 
kept  clean  and  cool,  llie  second  week  his  exercise  may  be 
increased  a  little,  and  so  may  hja  oau.  Should  he  appear, 
however,  rather  dull,  the  membrane  of  his  eyes  radicr  red  or 
yellow  on  lifting  the  eye-lid,  and  the  dung  bard,  in  small  knobs, 
and  sliining  or  slimy,  it  will  be  adviiiable  to  bleed  modcrutely, 
aod  give  a  mild  dose  of  phyiiic,  for  which  lie  sliould  be  piepnrt-d 
by  giving  two  or  three  bran  niafiltcs  n  day  fur  two  days.  The 
fourth  week  he  may  be  worked  moderately,  and  if  wanted  for 
hunting,  he  should  be  put  into  a  canter  or  hand-gallop  once  a 
day:  and  after  x\m  it  will  be  necessary  to  increase  his  pace 
twice  or  three  llmt-s  n  wc^-k,  so  as  to  make  him  sweat  frwly; 
taking  care  that  hi-  i*  walked  for  sonH-  lime  afterward,  that  he ' 
may  become  railH.-r  cool  before  lie  returns  to  the  stable,  when 
he  must  be  well  dressed,  fed,  and  watered,  have  a  good  bed 
placed  tinder  him,  and  he  lel^  to  bis  repose.  When  a  horse  has 
jxen  brought  up  from  rich  pasture  he  is  generally  loaded  with  >

into  good  condition,  considenthle  eare  and  coiistniit  alleutiuii 
are  necessBry.  To  give  bulk  and  strength  to  the  iiuik-W,  a 
good  supply  of  nutritious  food  is  required ;  but  in  order  that  this 
should  not  produce  su|>er6uous  fat  as  well  as  flesh,  plenty  of 
exercise  and  occasional  sweating  is  necessary. 

A  fine  glossy  cool  is  next  essential,  which  can  oidy  In-  ob- 
ta!ne<l  by  heat,  assintetl  by  plenty  of  grooming  and  hand- nibbing. 
The  "lalile  must  Im-  kejn  nitK^-i-ntely  warm,  hut  it  tntist  be  borne

Since  the  former  editions  of  this  work  were  published,  ilie 
pnictice  of  clipping  and  singeing  has  been  introdnced.  and,  it 
must  he  confessed,  with  considerable  advantage.  Where  a  fine 
coal  can  be  oblaJtu-d  by  the  means  before  mentioned,  clipping  is 
not  required  ;  but  many  hor^-s  will  carry  a  long  thick  coat  in 
the  winter,  in  spile  of  all  grooming,  and  in  others,  it  is  impos* 
sible  10  he«low  the  necoiidary  attention  and  expenw  required. 
In  ihL>se  cases,  by  removing  the  coal  with  ihc  scissors,  the  horae 
ihat  before  could  not  travel  a  mile  without  sweating,  can  now

ditional  clothina;  to  supply  that  which  is  removed,  and  care 
must  be  taken  that  he  does  not  stand  still  when  without  it,  as, 
of  course,  he  is  more  likely  to  take  cold  from  this  cause  than 
before.  The  fact  is,  the  horse  must  have  a  teniporory  coat 
instead  of  a  permanent  one,  one  that  can  be  removed  when  at 
work  and  supplied  when  at  rest. 

The  advanti^es  of  clipping  are  unquestionable;  many  horses 
can  thereby  be  kept  in  condition  throughout  the  winter  that 
cannot  by  any  other  method. 

The  chief  difference  between  singeing  and  clipping  is,  that 
by  the  former  the  hair  is  removed  more  completely;  by  the 
latter,  it  can  be  done  sereral  times  during  the  season. — Ed.] 

niHECnONS    FOR   HAHAGINO    A    MORSE    DI7R1NG    A    JOURNEY. 

Previously  to  setting  off  on  a  journey  the  horse  should  be 
brou^t  into  good  condition  by  being  worked  out  for  two  hours 
every  morning,  and  fed  as  I  have  directed  in  the  chapters  on 
feeding  and  exercise.  The  feet  should  be  carefully  attended  to, 
and  if  they  are  dry  and  brittle,  the  soles  should  be  stopped  a  few 
ilays  with  cow-dung,  then  pared  rather  thin,  and  for  about  a 
week  before  he  h^ins  bis  journey  the  feet  should  be  kept 
stopped  with  tar  ointment,  which  is  then  much  better  than  clay 
or  cow-dung,  and  in  the  course  of  a  week  will  considerably  im- 
prove the  quality  of  the  horn,  and  tend  in  a  considerable  degree 
to  cool  the  feeL  This  ointment  is  of  great  use,  also,  about  the 
beets  of  the  frog  and  coronet,  especially  when  they  are  dry  and 
cracky.  A  horse  had  better  be  new  slioed  about  the  same 
time ;  for  when  it  is  done  just  before  he  sets  off,  the  shoe  may 
not  fit  exactly,  or  a  nail  may  be  driven  too  close,  and  the  horse 
be  found  lame  in  consequence  during  the  first  or  second  stage. 
The  saddle  or  harness  should  be  carefully  examined,  as  much 
inconvenience  sometimes  arises  during  a  journey  from  saddle  or 
harness  galls.  The  most  important  thing  to  be  attended  to 
dormg  ft  journey  is  the  method  of  feeding,  as,  by  improper 
management  in  this  respect,  not  only  great  inconvenience  and 
delay  often  arise,  but  sometimes  the  most  serious  diseases  are 
the  consequence.  The  hay  should  be  examined,  and  the  beat  that 
can  be  obtained  should  be  given.  It  is  usual  not  to  limit  the  horse 
in  hay ;  but  leave  that  part  of  his  diet  entirely  to  the  discretion 
of  the  osder,  who  takes  care  to  keep  the  rack  full.  If  a  horse 
travels  every  day  from  ten  to  twenty  miles,  one  peck  and  a  half 
of  com  will  not  be  too  much  for  him,  provided  he  has  only 
about  6  lbs.  of  hay,  and  the  less  hay  he  has  the  better;  for  by 
distending  the  stomach  a  morbid  appetite  is  produced,  whicli 
leads  a  horse  to  eat  and  drink  much  more  than  is  proper  for 
him,  and  this  often  proceeds  to  a  depraved  or  voracious  appetite,

which  leaiU  tiim  to  eat  even  hit  Itltcr.  While  I  was  in  practice 
at  Exeter,  and  ntli-nded  the  horsra  of  comnH'rciul  imvellert,  I 
met  with  nuineroiis  csnw*  of  cough,  hroken  wind,  gripe*,  Mid 
oihiT  (liHt^isc!!  nr(K)tice<l  by  lhi«  akuik-.  So  common,  inileed,  it 
tlic  praclicL-  of  givinf^  too  nitiolt  hny,  that  inoat  horseji  huve 
a.  greater  appetite  than  in  the  natural  healthy  state;  the  ca- 
pacity of  the  stomach  having  been  increased  by  frequent  dis- 
tention, and  the  capacitv  of  the  lungs,  or  wind,  not  unirequently 
proportionahly  diminished.  When  a  horse  comes  tn  from  s 
Btagc.  the  feet  sliould  be  picked  out  and  cxuiiiitivd  tlw  first  thing; 
and  the  common  pructice  of  tying  up  a  hone  at  a  stable  door, 
and  wiuliiiif:  Iuh  legx,  is  not  injurious  if  the  hurai'  i%  coul  imd  lias 
been  wnlked  <]uieily  in ;  but  ho  tiliould  never  be  taken  to  a  I'irer 
to  be  wimlied.  The  home  ithould  never  be  put  in  a  hot  close 
stable,  however  comfortable  it  may  appear,  nor  is  a  dark  stable 
desirable,  unless  a  hoi-sc  is  very  tired,  and  then,  perhaps,  ho  lies 
down  moiv  readily.  When  there  is  no  work  for  a  horse,  he 
should  always  he  Uiken  out  and  have  one  hour's  exercise,  at  least, 
ffwly  in  the  morning;  Iw  may  iIhii  have  bin  full  feed  without 
injury,  and  be  jierfecity  fit  for  tli«  work  he  it  wanted  for;  but 
when  this  cannot  be  done,  e^jKciallv  for  two  or  three  days,  he 
should  have  less  eorn  and  some  cold  mashes.  These  few  hints 
will,  perhaps,  be  acceptable  lo  the  young  traveller ;  and  if  any 
disease  or  acctdcni  happens  during  tlie  journey,  he  will  find  it 
tioticcd  in  this  volume.

CHAP.  V. 

A    OCMEftAL   VIKW    or  TIIK    rTRUCTVIIE    UP   THE    HOUSE. 

[Aniual  bodies  difTcr  ffom  iboee  of  vegetables  chiefly  in  ihe 
pooacoaiop  of  sensation  and  voluntar)-  motion.  WliiUt  the 
vegetable  is  confined  to  the  soil  in  which  it  is  located,  and 
derives  its  subsistctvcc  from  ilie  surrounding  clcmenta,  animals 
have  ihv  power  of  moving  from  place  to  place,  and  of  gratifying 
the  various  »cn«ilions  with  which  they  arc  endowed.  The 
Structure  of  animnlif  is  conu-ciuently,  much  more  complicated 
than  that  of  vcgeUtblt-A ;  but  in  proiwriion  as  an  animal  is  low  in 
ibe  sole  of  creation  —  at  it  approaches  u  slate  of  vi-gelable 
ffxistencc  —  we  lind  its  structure  more  simple^ its  sensatioiu 
fewer,  but  its  vitality  Kreatcr. 

In  the  lione  we  have  n  high  decree  of  organization,  and 
eonsicqiMnilly  a  vast  variety  of  complex  etniclure*. 

The  body  is  conipOM-d  of  »olitU  and  fluids ;  the  latter  exceed- 
ing the  former  in  weight  in  the  pruiwriion  of  »ix  or  eight  to 
one.  To  the  solid*,  however,  is  owin^  the  organixation  of  the 
frame;  for  they  surround  and  contain  the  fluids.  Late  ana to> 
miau  consider  that  animals  are  composed  of  three  forms  of  tissues, 
which  they  have  denominated  llie  Ji/irout,  the  lamdlar,  and  the 
globular.  The  two  former  are  exemplified  in  the  structure  of 
the  ttlltilar  substance,  which  composes  the  greatest  portion  of 
the  animal  fabric :  the  fibrous  is  clmracterisEic  of  the  muscidar 
and  lisamentous  structures:  the  fibrous,  united  with  the  granular, 
is  exhibited  in  tlie  texture  of  the  glands,  and  in  the  medullaiy 
substance  of  the  nervous  system ;  and  the  globidar  is  shown  in 
Ihe  composition  of  the  chyle,  the  blood,  and  several  of  the  secre- 
tions. Tliese  several  textures  being  combined  together  in  dif- 
ferent proportions,  we  have  the  various  organs  of  which  the  body 
is  composed. 

To  give  support  to  the  animal  frame,  aiul  afford  fixed  objects 
for  the  attachment  of  various  parts,  \*  the  u.te  of  the  skeleton, 
which  is  com[)oeed  in  the  horse  of  m-iirly  two  hundred  bones  of 
Tarious  sizes  and  slmpes.  These  bones,  in  order  to  admit  of 
motion,  are  connected  one  to  another  by  ineana  of  strong  bands, 
called  ligaments ;  the  ends  of  the  bones  being  constructed  in

form  ofa  hiiigei  in  olWrs  that  of  a  ball  and  socket. 

Tlie  motion  of  the  limbs  Is  cffvctnl  by  mrans  of  the  miucln 
or  Reah,  which,  altliou);h  to  u  castial  obstrvor  appearing  a»  a 
homog^iicoug  mass,  is  n-avlily  scpuntbk*  into  a  f^n-akT  number  of 
distinct  bodies  of  vtirioti*  forms  and  »i/i-».  Thnv  miucln  lutvv 
commonly  two  ecpnralc  atlaclimc^iita,  which  nrv  usually  bono*, 
and,  by  contracting  in  lcnj;th,  ibcy  bring  Ume  |winu  of  attach* 
miritt  nearer  to  ivtch  oilier.  Mtiscles  are  cc>tn[>osed  of  •  vut

diinini"))  in  Imf^th  and  increase  in  bulk,  aiid  tliercby  approxi- 
mate the  dilferent  objects  to  which  ihey  are  atlaclu'd.  'nn-y  are 
Uliially  f(kstencd  to  buiit^  by  means  of  s  strong  wliite  subslaitce 
called  tendon,  which,  however,  possesses  in  itself  oo  {Mwer  of 
coiitructiou,  but  ntei^y  communicates  the  contractile  force  to 
the  object  lo  be  acted  on.  Where  the  two  objects  of  attachment 
are  distant  from  each  other,  the  greater  portion  of  the  distance 
is  occupied  by  the  ten<lons,  the  advantage  of  which  is  obtained 
from  llieir  dimiiii^hed  sixe  in  proportion  to  their  strength :  thus 
wc  find  the  legs  of  horses  below  the  knee  arc  light  and  slefid«T, 
from  the  absence  of  muscular  and  the  substitution  of  tendinous 
Eubslaiice.  The  greater  pnrt  of  (lie  musck-s  arc  voluntary,  being 
under  ilie  oonlrol  of  the  mind;  but  some  are  involuntary,  »ucb 
m  iho  henri  and  the  diaphragm. 

Mii*des  are  extensively  Kiipplied  with  vcxscls  of  vartoii*  kiiitb) 
such  ns  arteries  fur  their  nourinhmenl,  and  veins  for  tlie  return 
of  the  blood  after  this  purpose  is  effected.  There  are  likewise 
nerves,  which  not  only  furnish  sensation,  bulaUocommunicalv  to 
llieni  the  mandates  of  llic  will. 

These  nerves  proceed  wthcr  from  the  bruin  or  Npinal  cord, 
which,  therefore,  may  bv  considt'n-<l  as  the  foitniuin  of  si 'n  sal  ton. 
and  the  ixvidenco  of  the  mind;  and  thus  K-ntatioii  h  first  sent 
from  the  extremities  to  the  brain  by  the  nerves,  and  thou  by 
another  set  of  nerves  the  will  is  conveyed  to  the  muscles. 

The  brain  is  a  soft  pulpy  sulMtanee  contuine<l  within  the  heiwl, 
and  the  spinal  cord  is  somewhat  Kimilar  in  appearance,  ami 
extends  from  the  brain  to  die  tail,  through  a  hole  in  the  bones 
which  form  the  spinal  colunm. 

The  body  b  dividixl  into  two  principal  cavities  the  ehvsl  M>d 
the  abdomen;  and  sepamte<l  by  a  muscular  partition  called  i)»e 
diapliragm.  The  former  contains  tlie  lungs  and  heart,  whose 
uses  are  to  purify  and  dttlribute  ilie  blood  by  nvenns  of  respiration 
and  the  circulation;  and  tttc  latter  contains  ttie  stomach  and 
bowels,  in  which  the  functions  of  digestion  are  carried  on,  besides 
several  important  glands,  such  as  the  liver,  kidivey,  and  jMiiereas, 
logelher  with  other  supplemeniary  parts.

stonuich  by  means  of  a  long  muscular  tube  which  powes  tbnougli 
the  cavity  of  the  chest.  In  tlie  stomach  the  food  is  acted  on 
by  a  peculiar  6uid  called  the  gastric  juice,  and  is  then  passed 
into  ine  small  intestin<fi,  where  the  chymo,  as  lite  food  is  then 
callcil,  becomt^  mixed  with  the  bile,  a  yellow  fluid  secreted  by 
ihc  liver.  Itoth  ihc  small  and  large  intestines  are  fastened  to 
the  n>ine  by  nieatis  of  a  Kirong  membrane  called  (he  metvntPry, 
which,  bc«ide«  veins  and  ariones,  arc  furnished  with  a  vast 
nitmb<-r  of  xmall  vm«cU  mllod  Inctenls.  These  lactealsopcn  into

blood  l><;con>es  euriclKd  wiih  nutriment,  and  is  thus  enabled  to 
supply  l)»e  coiiMxnt  waste  the  system  tt  continually  underftoinj^. 

'file  blood  being  furnished  with  nutriment,  requires  to  be 
purified  before  it  is  fit  for  cireulniioit :  for  this  purpose  it  pusses 
into  tl>e  riglit  side  of  the  heart,  by  ihv  miucular  contraction  of 
which  it  is  sent  to  the  lungs,  whm  it  become*  exposed  to  the 
nciiun  of  the  atmosphere,  hy  which  it  is  changed  from  a  dark  to 
a  light  re<)  colour,  and  being  freed  from  impurities,  it  enter*  the 
left  aide  oftlie  licwt,  and  from  lltence  is  H-nt,  by  means  of  the 
arteries,  lo  all  parts  of  the  body,  supplying  every  part  with 
nourisliment,  and  also  tlie  various  glsiuU  of  the  bwly  not  only 
with  their  own  proper  nourish motit,  hut  with  materiel  for  the 
secretion  of  their  jieculiar  fluid-i.  'I'lms,  the  salivary  glands 
separate  tite  Koliva  from  the  blood;  the  pancreas  a  juice  some- 
what similar;  tlie  testicles  the  semeu ;  and  the  kidneys  the 
urine.  Each  gland  separates  iu  peculiar  fluid  and  no  other. 
The  urine,  ln-itig  WTreied  by  the  kidneys,  is  conveyed  by  means 
of  two  small  hui  long  lube^  into  the  hliidder,  whence  it  is  ex- 
creted from  tlH>  l>ody. 

Tl)«  liver  is  nourinhcd  by  the  arteries,  but  separates  the  bile 
from  the  dark  impure  blood,  which  is  conveyed  to  it  by  a  targe 
Tein. 

The  contents  of  the  Iniwels  are  pasied  onwards  by  the  influence 
of  their  peciilinr  action,  and  having  hud  the  nutritious  part  ex- 
tracted, are  excreini  from  the  body  geiieriilly  in  a  solid  lorm. 

'llie  ctUuhir  membrane  is  a  vei'y  eluiiiic  sultsiance,  and  enters 
largely  into  tlH>  compovitiou  of  the  body  j  it  connects  the  various 
glands  together;  funns  frequently  a  eoverinj!  for  the  muscles  as 
well  as  fur  various  vcs.selis  ond  exiits  in  the  form  of  cells,  which 
have  communiciiiiflu  with  ea';h  other.

Tlteio  lire  two  other  important  nienibranes  which  are  exten- 
sively Touiid  in  aniinid  lx>dif£>;  they  are  the  serous  and  mucous 
membranes.  Wlienever  aii  internal  part  has  an  externa)  oneo-

secretes  miieus  for  iia  protection ;  but  when  ilie  cavity  bos  tio 
external  opening,  that  it  is  lined  with  a  serous  membranev 
wliicli  secretes  a  thin  watery  fluid  to  lubricate  the  parts,  and 
pn-serre  (hem  from  injury  by  friction.  Thus  from  the  entrance 
of  the  mouth  and  nostrils  to  the  anus,  throuftbout  the  whole  in- 
tcritnl  surface  of  the  bowett,  a  mucous  membrane  exists,  by  which 
the  fluid  i«  secreted,  the  nature  of  which  gives  a  name  lo  Uk 
membrnne,  and  which  protects  it  from  injury  ^tbcr  by  t]>c 
exteniul  uir,  or  by  the  contents  of  the  boweU.  Jii  like  manner, 
we  find  the  bladder  and  urinarj'  organs  Mmilurly  Hn<-d. 

On  the  other  hand,  the  cavity  of  the  elH'»t  and  tlie  MbtlonioD, 
witli  their  contcntt,  (Ui  well  as  the  intcnud  unrface  of  bloutl> 
vessels,  arc  furnislied  with  a  trraiu  inembmne,  which  secretes  * 
watery  vapour. 

These  difrerviit  membranes  are  very  fn-qnemiy  the  seat  of 
disease,  and  are  siiibject  lo  Mvere  and  dangeront  inllnmriiatioRS. 

The  adniimhie  inunner  in  which  the  various  orgiUH  arc  pocked 
away  in  ilieir  proper  cavities  is  worthy  uf  ]Mkr(icular  noticv. 
'Itic  lungs  and  tho  lieurt  are  so  adapted  to  the  shape  of  tbcr 
cltc»t,  that  there  is  iit  no  time  iiuy  vacant  spot;  and  the  more

[The  skeleton  of  antrnal  bodies  is  fomieil  of  bone,  a  subatatice 

possessing  flrmncss  and  stability  for  tlie  aitaehinent  of  muscles, 

ttlio  protection  of  the  vital  organs,  and  the  supjmrt  of  the  soAer 

parts.     It  is  composed  of  animal  matter  and  earthy  salts ;  the

former  comisiing  of  rariiln^.  gclntrnp,  and  f&t  or  marrow,  and 
the  Inttcr  of  pJionpliaii-  ol'  linio  in  considcrablo  proportion,  a  lesaer 
qunnlity  of  cnrboiiair  of  lime,  and  a  small  portion  of  otl>crr  salts.

the  bone.  On  the  otbei'  hand,  bones  by  exposure  to  a  great 
beat  are  deprived  of  the  animal  substances,  and  the  earthy  part 
remains. 

The  use  of  the  marrow  is  more  particularly  to  prevent  the  too 
great  dryness  and  brittleness  of  bones.  To  the  animal  portion 
of  llieir  composition  arc  they,  tliereforr,  indebted  for  their  shape 
and  wliat  ilegix-r  of  elasticity  they  possctt,  and  from  (he  earthy 
portion  they  derive  the  important  purposes  of  *trmglh  and  sta- 
bility. Thiw  arc  thi-sc  different  demciitK  combined  tog^ther^ 
atul  by  an  union  of  their  different  principU-it  form  n  *ub*tance 
admirably  adapted  for  afiitrding  full  scope  for  the  piny  of  the 
various  offfans  of  life,  protecting  at  the  same  time  the  vital  ports 
ffx>m  external  injurv,  admitting  and  assisting  the  |mwcrH  of 
locomotion,  and,  in  fine,  forming  a  secure  fabric  for  the  beiiuiiful 
building  of  animal  frames.  Every  bone  is  covered  by  a  mem- 
brane called  the  peri<»teum,  which  also  lines  the  internal  ca- 
rities,  and  secretes  the  marrow :  its  use  is  to  circumscribe  (be 
(brm  of  bones,  and  protect  them  by  ite  tenseness,  as  well  as  to 
affiird  the  medium  whereby  they  arc  furnished  with  their  vessels. 
The  sitapc  of  particular  bones  intimately  corresponds  to  ibe 
purpose  for  wliicb  they  are  Jntenihti :  where  for  the  office  of  pro- 
tection, we  lind  ihein  flat,  and  where  for  the  purpose  of  motion, 
lontj  and  cylindrical,  lu  in  theexireinitio^  in  the  construct  ion  of 
tlicnlcull  tliernost  perfect  mccliani^m  i«  displayed.  The  fu'sl  object 
to  be  obtained  it  lite  protection  of  the  brain  from  the  accidents 
to  which,  from  the  peculiarities  of  animals,  it  is  mostly  exposed. 
For  this  purpose  the  skull  consists  of  two  tables  or  plates;  the 
outer  thick  and  tough,  the  inner  hard  and  brittle :  the  former,  by 
yielding  in  a  measure  to  resistance,  diminishes  concussion,  wbikt 
the  latter  by  its  hardness  prevents  sharp  bodies  from  )H'netrating 
to  the  brain.  Now,  if  these  (wo  plates  were  reverwd,  (Ih-  Itriltie 
would  not  only  be  tn  great  danger  of  fracture,  but  would  also 
vibrate  considerably;  and  the  injurious  effect  of  this  vibration 
may  well  be  conceived  when  we  are  told  that,  even  with  the  pre-

might  find  thU  mode  of  union  serviceable  in  joining  the  sltte^i  of 
a  wooden  box,  a  workman  would  by  no  means  find  it  auplicablu 
in  connecting  together  brittle  siibiiances,  Bs  it  would  be  ex> 
emely  liable  to  chip  off  at  tlie  edge*.

Thcro  arc  no  leas  than  nine  bones  which  enter  into  the  conijio- 
■ilioii  of  the  cranium.  The  (hvj  t'rontai  bones  form  the  anterior 
part,  usually  called  the  rorcliead  ;  but  the  internal  plate  of  these 
bone*  separates  and  recedes  from  the  extcrtial  plate  so  as  to  form 
a  cuviiy  between  them,  which  is  cnlled  the  frontal  sinus,  and  \b 
divided  by  n  u'ptum  or  ridge  of  bone  bclwi-en  lliem :  the  inter- 
nal itlatc  fonns  a  coverini;  for  the  anterior  lobe  of  the  cerebrum.

IrlB  of  the  cranium,  and  cover  the  middle  lobes  of  the  cere-

lies  become  closelv  united  after  the  second  or  ttiird  year. 

'Ilie  OeripitaJ,  a  smgle  bone  of  great  strength,  ts  found  at  the 

,ck  and  base  of  the  cranium.  Its  internal  eurlace  covers  the 
cerebellum,  and  on  a  strong  process  at  the  hose  the  medulla 
oblongata  rests.  The  external  surface  of  this  bone  is  extremely 
irregular.  At  its  upper  part  wc  find  a  crest  or  iidge  of  Iwim-, 
to  which  the  cervical  ligament  w  altacheil,  iii«  well  a:*  Kevcral 
muscles  of  the  iKck.  Ueluw  this  is  llic  occipiul  bote,  through

to  what  order  tlie  aninml  mi^ht  have  belonged.  In  herbivorous 
nice*  a  grinding  luieral  motion  of  rhe  jnws  onlv  is  required,  and, 
necordiiigly,  the  nriiculation  is  wide  and  shallow.  The  lyco-

to  nfibrd  nwre  room  for  tlie  development  of  tlic  temporal  muscle 
which  governs  the  jaws,  than  ia  required  for  the  more  moderate 
exertions  of  herbivorous  animaU.

orifices  for  tlie  passage  of  the  auditory  nprvo,  ami  on  theexlertwil 
part  we  fin<i  a  larger  orifice  for  the  pniuage  of  Mund.  The 
internal  struciure  of  this  lione  is  n*  bi-aniiful  as  it  is  curious;

and  u  singular  cavity  having  a  communication  with  the  mouth, 
in  which  are  discovered  four  diminutive  bones,  with  their  corre- 
sponding muscles,  which  serve  the  purpose  of  projiagating  and 
modifying  the  sound. 

The  inferior  and  middle  parts  of  the  cnuiium  are  formed 
principally  by  the  Sphrtwiil,  a  hone  which  somewhat  resembles  a 
bird  in  flight,  having  a  body  and  four  prooeeaee,  two  of  which 
are  called  tlic  wings,  and  two  the  legs.  This  bone  support*  the 
middle  lobe*  of  iti«  cerebrum,  and  presents  several  Iwles  and 
denretsioiu  for  the  passage  of  nervc». 

I'he  cranial  cavity  is  separated  from  the  nonal  by  (he  Ethmoid 
bone,  which  also  somewhat  resembles  a  bird  in  flight,  but  with- 
out legs,  and  is  situated  in  front  of  tlie  Itone  la^t  described.  It 
supports  the  anterior  lobes  of  the  cerebrum,  and  has  holes  for 
the  exit  of  the  olfactory  nerves:  and  on  its  internal  and  inferior 
surface  it  funus  cavities,  called  the  ethmoidal  sinuses,  which  are

by  A  va»t  nimiber  of  small  holes  for  the  passage  of  the  olfactory

middle  bv  a  suture.  They  also  form  (he  greater  portion  of  the 
nasal  cavny,  thus  having  three  surfaces,  the  facial,  the  nasal,  and 
thepalaiine. 

TIm!  Antrrior  or  Inferior  Maxiihr^  bones  arc  singular,  inas- 
much as  ilM-y  are  wanting  in  the  human  subject.  They  com- 
mence in  tlw  angle  foritH'<l  by  tlic  separation  of  the  nasal  from

irregular  in  shape,  a  pan  being  situated  within  ilw  orbit  of  lh«

upper  part  assists  in  lorniiiig  the  zygomaiic  arch,  from  whence  a 
ridge  of  bone,  called  the  xy^omaiic  ^pine,  is  continued  downwards, 
not  only  to  the  extent  of  thi^e  bones,  but  also  to  that  of  two 
inches  of  iIk  superior  maxillary  bones. 

The  Laejir^mal  bones,  so  called  because  llie  lachrymal  duct 
for  the  conveyance  of  the  snpei-fluous  tears  to  the  nostrils  passes 
through  ihem.  is  situated  about  half  within  and  half  witltout  the

separated  into  two  distinct  cavities. 

Tht"  Itjirior  ^LtyiHar^,  or  lower  jaw  bone,  is  formed  of  two 
symmetrical  halves,  united  at  the  inferior  part  bv  cartilage  in 
the  young  subject,  but  by  bone  in  tho  adult.  This  united  por-  | 
tion  forms  deep  and  strons  sockets  for  the  inferior  inci»or  tccih,  ' 
and  posterior  to  tliU  for  tl»c  titsks;  abovi-  ihU,  each  half  sepa-

minates in  rounded  extreniities  wliieh  correspond  to  ll>e  glenoid 
cavity  in  the  temporal  bone  before  di-scribed,  thus  forming  the 
maxillary  joint. 

The  bone^  which  we  have  nu^ntioned  a.i  composing  the  face 
are  none  of  them  solid  in  their  structure:  but  in  oi-der  iliat  the 
requisite  amount  of  surface  nhould  exist  witlioul  too  great  weight, 
ihey  are  moat  of  tlieia  hollow;  and  tliua  various  sinuses  are 
formed,  which  are  called  after  the  bones  in  which  they  are  found. 
First  we  have  t\w  frontal  timtitx,  which  are  situated  between  llie 
orbits;  they  are  triangular  in  shape,  tlieir  flat  surface  beinc 
above,  and  two  irregular  ones  below:  ihey  itave  inferiorly  blittd 
terminations,  which  are  called  the  nasal  sinuses,  being  in  tira 
nasal  bones;  and  ihey  comniutiieiile  with  the  maxillary  sinuses, 
which  are  situated  sotnenhal  below  and  in  front  oftliem. 

The  MatiUary  are  the  Urgest  of  the  sinuses  of  the  liead,  ex- 
tremely irregular  in  shape,  and  are  formed  principally  by  the 
superior  ma>ullBry  bones  :  their  upper  part  is  separated  from  the 
orbit  by  tlic  lachrymal  and  malar  bones,  which  form  their  supe- 
rior partu;  their  lower  extremity  is  blind,  Inil  above  this  there 
is  an  o[)Ciiing  into  ihe  chamber  of  the  noKlrils,  besides  the  com- 
munication before  K|)oken  of  with  the  frontal  sinus. 

'lliere  are  oilier  ntnaJI  sinuse*,  culled  the  SphmoidaU  i)>e  EUi- 
utoidalt  and  the  Pataliue,  being  found  within  tlie  iKme^t  after 
which  tltey  are  callei).  The  fnst  of  these  ik  a  single  siniiv,  and 
llie  last  is  situated  between  the  palatine  and  the  maxillary  bonen. 

These  singular  cavities  are  not  found  in  the  young  subject, 
but  are  gradually  formed  as  the  sise  of  the  head  increases :  one 
important  purpose  which  ihev  therefore  serve  is,  to  increase  the 
size  of  the  head,  without  adding  to  iu  gravity.  'I~hese  sinuses 
are  often  the  seat  of  disease  in  f^anders,  when  they  often  contain

brain  itself;  and,  lastly,  it  is  in  animals  the  fixed  object  from 
whence  the  bead  is  suspended.  If  the  protection  of  ilie  spinal 
marrow  were  the  only  object  to  be  effected,  it  would  have  oeeti 
simply  a  strong  Imny  tube:  but  whilst  it  potaesses  great  strength 
for  this  purpc»e,  eoniiderable  flexibility  is  also  required,  and 
accordingly  it  is  composed  of  a  multitude  of  bones,  more  or  less 
in  different  animals,  according  to  their  wants  and  habits.  The 
feline  races  rctjuirc  tlte  utmost  degree  of  elasticity,  in  order  to 
climb  up  and  spring  from  eminences,  and  seixe  their  prey  with 
facility ;  but  if  these  animals  eould  be  tamed  sufficiently  to  make

little  st-rvicc  in  tliis  new  capacity,  from  the  want  of  *lrength  and

aary  horixoninl  motion  reotiired  by  the  animal,  die  secomi  vcr> 
tebra  is  called  into  requiBilion,  and  ilf  odontoid  proct^ii  fits  into 
a  cavity  in  the  under  and  posterior  surface  of  the  nilil*,  And 
forms  a  siifGcieni  resemblance  to  a  ball  and  socket  jatnt  to  allow 
confidvrable  laternl  motion.  We  cannot  sufficiently  admire  tlie 
beautiful  mechanism  by  which  ih<-»c  important  movements  arc 
safely  secured ;  the  second  joint  would  have  been  as  inapplicublo 
for  the  uses  of  llie  first  a*  tbe  first  would  Iw  for  that  of  the 
second;  for  if  the  second  juint  ;i(lmitte(l  vertical  motion,  tbe 
consequence  would  be  ihiil  the  looth-liki-  proccm  would  be  forced 
against  the  spinal  marrow  every  time  the  head  was  bent  for- 
wards; but  by  the  actual  airaciure,  the  joint  beinj;  undemcntb  the 
spiiml  cord,  either  a  rotatory  or  a  vertical  motion  eim  be  safely 
enjoyed. 

The  remaining  bones  of  tlie  neck  are  very  similar  to  each 
other,  their  ehape  being  very  singular  and  irregular.  They 
have  each  a  large  hole  running  through  them,  for  the  passage  of 
the  spinal  marrow ;  a  ridge  on  tbe  upper  part  for  the  attachment 
of  the  cervical  ligament;  processes  on  the  side  for  the  inser- 
tion of  tbe  powerful  muscles  that  move  tbe  bead  and  neck;  antall 
foi^mina  or  holes,  for  the  pti^sa^c  of  ncrrrs  and  blood-vessels; 
and  on  the  anterior  part  a  round  head,  which  is  received  into  a 
cavity  in  the  back  part  of  the  bone  in  front  of  it ;  also  processes 
or  legs  which  proceed  from  the  front  part  of  each  bone,  and 
meet  and  correspond  with  similar  processes  on  the  back  part  of 
each  bone.  These  bones,  however,  never  actually  touch  eacli 
other,  fur  if  they  did  there  wotild  be  too  much  concussion  ;  but 
between  every  two  bones,  and  exieniling  throughout  the  whole 

Sine,  there  is  interposed  a  gristly  substance,  enclosetl  in  aa 
istic  body,  which  yields  and  recoils  like  an  air  cu»liinn.  In 
the  human  subject  this  power  of  dilatation  exiits  in  a  very  con> 
sidemble  degree,  owing  to  which  men  will  often  measure  mora 
in  the  morning  tlian  in  the  evening  after  their  daily  toil  is  com* 
pi  I- led. 

Though  in  horses  this  power  of  dilatation  is  not  possessed  in 
an  equivalent  ticgree,  yet  ilie  elastic  intervertebral  substance 
greatfy  contributes  to  the  elasticity  of  titc  frame.  Witli  tlie 
seven  bones  of  lite  neck  the  spine  is  composed  of  no  less  titan 
tliirty  separate  piMOs,  which  are  dislinguishe<l  a«  iIh*  dorsal,  or

M>nie  o)i|Kind(-d  out  liim  the  fonn  ot  tho  human  hand,  in  others 
cou*oli(hiti-d  and  protected  t>y  a  horny  ca^e,  we  cannot  wonder 
at  inch  an  idea  being  entertained.  11»e  aiiatomist,  however, 
lind.t  tiiat  this  diversity  ia  much  greater  in  appearance  than  in 
reality ;  indeed,  in  all  warm-blooded  animals  uicre  is  a  general 
resemblance,  all  Itaving  Tour  puis  in  common,  vis.  the  shoulder, 
the  arm,  the  foi'earm,  and  the  metacarpus,  or  s)uink.  The  most 
striking  variety  obtains  in  the  mode  of  connection  with  tt>e  body. 
Whenevvr  the  fore  extremity  is  not  used  for  tho  |iHr]K>*c-  of  s\a- 
laining  the  body  or  for  locomotion,  but  tor  holding  and  retaining 
objectH)  as  in  man  and  in  monkeys,  or  for  that  of  flying,  as  jn 
birds  — where,  in  short,  a  degree  of  rotnlory  motion  is  required, 
the  connection  is  bony,  by  means  of  the  clavicle,  or  collar>bonc. 
But  in  animals  in  whom  the  weight  of  the  bodv  is  to  be  au^ 
tained  by  the  fore  extremities,  such  a  connection  would  be  inad- 
missible, and  would  expose  the  body  continually  to  concussions 
and  fraciurce.  In  moBt  cinadrniKxI^,  therefore,  the  connection  is 
by  means  of  muscle  or  flesh ;  the  body  is  in  fact  suspended,  like 
a  carriage  on  springs,  between  the  two  sJioulder- blades.  This 
it  ia  which  in  great  tncnsure  gives  that  springine&s  to  the  motions 
of  the  horse  so  delightful  to  iIh^  rider,  wbich  enables  him  to  alight 
from  the  higlu-sc  leaps  with  safety  to  himself,  and  to  l)ear  his 
mai>ter  barmlesi  over  a  brook  or  ditcit  nine  yards  wide.  To 
uccomplt^h  this  desirable  lacully  of  sustaining  great  burdens 
without  concussion,  free  motion  is  admitted  in  a  backward  and 
forwar<l,  but  scarcely  any  in  a  lateral  direction.  In  dog*  and 
cau  a  much  greater  degree  of  lulenil  motion  is  possessed,  but 
the  connection  with  the  body  k  considerably  weaker,  and  llie 
power  of  sustaining  much  weight  ix  not  possessed. 

All  animals  have  a  Scnpitla,  or  shoulder-blade,  which  in  the 
horse  is  a  flat  triangular  bone,  having  its  exttrrnal  surface  divided 
vertically  by  a  ridge,  which  ik-rve«  as  u  protection  and  an  ob_^t 
of  attachment  fur  muoelcs.  This  bone  is  flat,  in  order  to  aflbrd 
greater  space  for  connection  with  (be  body,  but  its  breadth 
diminishes  towards  the  lower  piirt,  for  the  purpose  of  forming  the 
shoulder  joint. 

The  JiumfTus,  tlic  next  bone,  is  rounded  at  its  upper  part* 
and  is  received  into  a  cavity  at  the  end  of  the  scapula,  wbich  is 
extremely  shallow  in  most  animnli^,  ns  there  is  but  little  danger 
ofdislocaiion  when  the  motion  of  the  limb»  iit  limited  to  two  direc- 
tions. In  man  the  motion  uf  the  joint  i«  much  more  extensive; 
and  although  the  cavity  is  considerably  <1iHi>er  in  htm,  ret  dis* 
location  freqiicnlly  takes  place.    The  humerus  is  a  cybndrical

[arlvitniage.  I'his  exteiuioi)  of  surface,  however,  is  procured 
,  wiihdutuny  ineresBed  weight;  for  there  being  but  liltle  danger 
[of  fracture  at  the  ends  of  bonrs,  great  strength  is  not  iliere  ce- 
IquireiL  The  bony  case  is  therefore  much  thinner  than  in  the 
,  middle  of  the  bone,  and  the  internal  part  is  filled  with  the  can- 
^celli,  or  bony  cells,  which  contain  the  marrow.  The  lower  portion 
fOf  tlte  humerus  forms  a  very  important  joint,  viz.  that  of  the 
eilmw,  which  in  man  admits  of  considerable  rotatory  motion :  hut 
I  in  the  horse,  as  Uterat  movement  is  not  required,  the  action  of 
'  the  joint  is  limited  to  one  direction,  backwards  and  forwardi, 
tftnd  thus  dislocation  never  takes  place. 

1'he  Forenrtn  is  composed  of  two  bones,  the  radius  and  the 
)itlna.  In  man,  botlk  hones  offer  separate  surfaces  for  articulation 
(*iih  both  tlie  elbow  and  the  wrist,  or  carpal  joint,  by  which 
|li>eans  the  arm  possesses  a  rotatory  motion;  but,  in  ilic  lioi-se, 
this  not  being  required,  die  strength  of  tlic  limb  is  concentrated 
I  in  the  radius,  anci  the  ulna  serves  merely  as  a  powerful  lever  for 
Itlie  attachment  of  muscles,  and  tti«  security  of  the  elbow  joint. 
[Hie  radius  is  liicrefore  a  strong  cylindrical  bone,  whilst  the  ulna 
large  at  the  upper  part,  which  rises  above  iho  radius,  and  is 
[attached  to  it,  and  gradually  tapers  downwards,  but  does  twt 
reach  tl>e  knee. 

The  Carputy  or,  as  it  is  commonly  termed  in  the  horse,  the 
I  linee,  corresponds  with  the  human  wrist,  although  apparently  so 
idifTerenl.  It  is  composed  of  seven  bones  in  the  horse  (one  less 
than  in  man),  which  arc  arranged  in  two  rows,  thus  forming 
three  distinct  joints  —  firstly,  ihjit  Ix-iwecn  the  radius  and  the  first 
row;  secondly,  between  the  fir»t  row  and  the  second;  and, 
thirdly,  beiween  the  last  and  the  mcltiairpnl  bones. 

Eacli  of  lltesc  joints  possesses  contitlerable  action,  moving  as 
it  were  like  w  many  hinges,  the  fulcra  of  which  are  placed  at 
the  back  ports  of  the  knee;  the  lowest  joint,  however,  does  not 
enjoy  so  much  latitude  of  motion  as  the  others.     One  of  the

t))c  writt  in  mati,  yet  tite  itorae  requires  a  certain  nuinbor  of 
buiies  and  joini.4,  in  order  to  obviate  the  coDcimioii  lo  which  he 
would  be  otherwise  liable;  for  ilia  neceesarjr  that  he  should  move 
with  great  celerilv,  and,  at  the  same  lime,  that  the  vital  organs 
^wtild  be  secui'ed  iVom  the  shock  that  would  be  experienced,  if 
the  same  concussion  that  tl>e  feet  received  were  communicated 
to  the  internal  organs.  To  accomplish  this  purpose,  the  joioU 
greatly  contribute;  and  none  more  so  than  titat  of  the  knei'y 
which  is  placed  at  an  equal  distance  between  the  body  and  the 
ground. 

To  neiitmlise  the  jar,  no  two  bones  arc  pormitled  to  touch 
each  other,  fur  each  is  tipped  with  cartilage  at  the  place  of 
junction,  and  is  covered  with  a  &ne  delicate  membrane,  by  which 
an  albuminous  6uid,  called  synovia,  it  secreted.  This  fluid,  being 
confined  by  what  is  called  the  capsular  ligament,  lubricates  the 
joint,  lakes  away  the  jar,  and  prevents  llie  bones  from  coming 
inld  contact  with  each  other.  The  im|)ortancc  of  this  fluid  is 
Itrikingly  shown  in  coses  where  the-  joint  is  opened  by  some 
Kvi<rc  injury,  and  tlie  synovia  <-scaping,  tlm  atmosphere  i* 
admitted ;  the  Bj*oovial  membruncs  come  in  contact,  and  tIte 
most  severe  inflammation  is  sot  up,  attended  with  excoftivc  jiain ; 
ami  the  result  frequently  it,  iinle««  the  cavity  cnn  be  quickly 
closed,  the  horse  either  dies  from  irritation,  or  the  motion  of  the 
joint  is  destroyed  by  the  secretion  uf  bony  tubslunce  in  and 
around  it. 

The  lower  row  of  the  knee  bones  rest  upon  the  metacarpus ; 
which  ill  man  and  many  animals  is  composcfl  of  four  bones, 
nearly  eouat  in  sixe,  but  in  the  liorsc  consists  of  ont?  liirge  and 
two  small  molacai'pal  bones.  The  large  one  is  coniinoiily  termed 
the  cannon,  and  forms  the  principal  bulk  of  llie  sli/uik,  being  u 
strong  cj'lindricat  bone,  oflen  a  fool  in  length,  neacliing  IVum  the 
knee  to  tlic  fetlock  joint.  Like  other  cyliiidri<.'al  bonet,  the 
cannon  is  smaller  in  tl>c  middle  and  larger  towards  tl>e  extre- 
mities. The  xmail  ntttacarptd,  or  splint  bono,  although  tliey 
form  a  portion  of  tlie  knei>  joint,  yet  do  not  reach  more  than 
three  fourths  of  tlw  length  of  the  shank.  Tliey  are  attached  to 
the  cannon  by  elastic  ligamentous  sulmance,  and  gradually  tiiper 
tbwnwai-ds,  and  end  in  bulbous  exEremiiica.  With  age  they 
become  consolidated  with  the  cannon,  and  in  many  horses  a 
boiiy-  subalance,  called  a  splint,  unites  them  even  in  youth. 

The  length  of  the  metacarpus  corresponds  inversely  with  that 
of  the  humerus,  and  in  proportion  m  (lie  former  is  long  and  the 
latter  is  short,  and  vice  vcr$ix.     1'\wa  in  man  tl»e  humerus   ia

THE   SKELETON.  3S 

long  and  the  metacarpus  s>iort,  whilst  in  the  horse  we  find  the 
latter  bones  long,  and  the  former  comparatively  short. 

The  bones  below  the  tetiock,  the  Phalange*,  which  in  carni- 
vorous animals  are  in  four  divisions,  in  the  horse  are  consolidated 
into  one.  Thus  we  have  the  firsi,  second,  and  third  phalange, 
with  a  supplementary  bone,  called  the  navicular,  or  shuttle  bone. 

The  first  phalange  is  called  the  0$  Siiffraginh,  or  large  pastern, 
which  receives  the  lower  extremity  of  the  cannon  on  its  upper 
surface,  having  depressions  corresponding  to  the  convexities  of 
the  cannon,  thus  forming  the^//ocA  joint.  Immediately  behind 
the  fetlock  joint,  and  indeed  entering  into  its  composition,  are 
two  small  triangular  bones,  called  the  gesaiiwidg.  They  are  sus- 
pended from  above  by  a  very  strong  ligament,  and  thus,  besides 
protecting  the  fetlock  joint,  are  the  means  of  affording  an  im- 
portant spring  to  the  animal.  The  large  pastern  rests  entirely 
on  the  small  pattern,  a  shorter  but  stronger  and  thicker  bone 
than  the  former;  thus  forming  the  pastern  joint,  the  frequent 
seat  of  those  bony  tumours  called  ringbones. 

The  small  pastern  bones  rest  upon  two  bones,  the  coffin,  or 
09  pedis,  and  the  navicular,  or  nut-bone,  thereby  forming  the 
coffin  joint.  The  coffin  bone  is  the  last  phalange,  and  by  means 
of  its  connection  comes  in  contact  with  the  graund.  It  is  a  very 
singular  bone,  both  in  its  shape  and  construction,  and  will  aflcr- 
waras  demand  our  more  particular  consideration.  It  corres- 
ponds in  great  measure  to  the  horny  hoof  to  which  it  is  attached. 
The  navicular  is  a  considerably  smaller  bone  lying  behind  the 
former,  supporting  a  portion  of  the  superincumbent  weight,  but 
affording  likewise  an  important  pulley  for  the  flexor  tendon. 
This  part  is  the  frequent  seal  of  disease. 

The  hind  extremity  of  quadrupeds  varies  much  from  the  fore 
in  the  manner  oNits  connection  to  the  body.  There  is  less 
weight  to  support,  and  consequently  there  is  less  danger  of  con- 
cussion ;  but  as  more  motion  is  required,  the  connection  is 
'formed  by  means  of  a  joint. 

The  upper  bone,  called  thejemar,  has  a  large  globular  head, 
which  is  received  into  a  deep  socket  formed  by  the  bones  of  the 
pelvis,  and  this  joint  is  secured  from  dislocation  not  only  by 
means  of  the  capsular  ligament,  but  likewise  by  one  of  immense 
strength  situated  within  the  joint.  Tlie  motion  of  this  joint  is 
greater  and  the  cavity  deeper  in  the  human  subject ;  but  in  the 
horse  the  motion  is  chiefly  limited  to  a  backward  and  forward 
course,  there  being  but  little  in  a  lateral  direction.  Thus 
the  horse  cannot,  like  the  human  subject,  stretch  his  legs  very 
wide  apart :  but,  however,  nearly  all  the  lateral  motion  that  the 
horse  possesses  in  the  hind  extremities  is  possessed  by  means  of 
this  joint,  there  being  scarcely  any  aflbrded  by  any  other.  The 
ftmvT  is  the  largest  bone  in  the  body,  and  is  extremely  irregular

in  sliape,  liaving  a  niinibcr  of  pro[ul>erancps  for  the  attachme^| 
of  muscles.      Its  loner  rn<l  articulates  with  the  tibia,  forminH 
what  is  commonly  termed  the  stifle  joitit,  and  which  corresponoi 
anatomically  vrith  the  human  knee.     As  an  additional  security, 
and  to  wanl  off  concussion,  there  are  two  elastic  substanco, 
called  from  their  ?hape  tlie  semilunar  cartilage^  interposed  he* 
twecn  the  hones  whicn  form  this  joint.     In  Ironi  we  find  a  small 
bone  called  the  pstelln.  or  knee-pan,  which  perfornia  the  office 
of  a  pulley,  receiving  from  above  tlte  tendons  of  lite  airuiig  ex- 
Itensor   muscles  of  the  thigh,  and   firmly  fastened  by  equally 
^  strong  ligHments  to  the  ijp|>er  attd  front  part  of  tlie  tibia.     In 
all  animals  the  length  of  the  femur  depeniis  on  that  of  the  meta- 
tarsus: in  horses  and  cattle  the  latter  is  verj-  long,  and  the 
former  short ;  whilst  in  man  and  in  many  anintals  we  diKOver 
an  opposite  arrangement.     In  man  the  lee  is  formed  by  tiro 
bonn,  the  tibia  and  tUcjUiitla,  both  of  which  enter  into  the  com- 
position of  the  joint,  and  thus  afford  a  considenihle  extent  of 
L  motion  in  every  direction.     In  horses,  however,  the  fibuU  ii 
l-altogethcr  small  and  unimportant,  the  leg  being  almost  entirely 
I  formed  by  the  libia,  which  in  the  horse  is  much  longer  than  the 
r femur,  and  its  loivcr  end  communicates  with  tiie  tarsal  joint,  or, 
as  it  is  commonly  termed,  tlie  hock.     The  tibia  extends  ob- 
liquely backwards  from  the  stifle  joint,  whilst  the  femur  extend* 
from  above  in  a  contrary  direction,  thus  forming  an  angle  which 
'  is  more  or  less  acute  in  diflV-rent  nnimak,  being  in  speedy  animalB 
}  much  more  acute  than  in  slower  ones. 

The  hoeA   is  compo.'>ed  of  no  less  than  six  bones,  but  the 

motion  of  the  joint  is  almost  entirely  confined  to  Uic  upper  bonci 

ihe  attraffaliir,  which  articulates  wiili  the  tibi&     In  the  human 

•ubjecl,  llie  lariiin  rests  on  the  ground,  and  the  various  bone* 

whicli  compose  it,  constructed  in  the  form  «f  an  arcli,  form  a

the  ground ;  bui  there  arc  many  who  tread  on  the  various  nlia- 

langn,  wliilst  the  hor»e  treads  eiuirely  on  the  last  toe.     'I  hus, 

with  the  long  metatarsal  bone,  which  closely  resembles  the  meta- 

carpus  in  the  fore  extremity,  the  hock  is  elevated  considerably 

from  llie  ground  in  a  similar  manner  to  the  knee,  but,  unlike 

I  this  joint,  it  forniji  an  angle  from  the  metatarsus  extending  for- 

Iwards  under  the  body  of  the  hoi-se.     Tiie  upper  joint  of  tlic 

fbock  pos>c«»c«  very  considerable  extent  of  motion  in  a  forward 

'direction,  but  none  laterally;  and  the  joint  is  accordingly  con- 

uructed  on  tlic  principle  of  the  hinge,  and  secured  from  di«lo> 

cation  by  means  of  two  condyles,  or  rounded  prominences,  on 

lb*-  U])p>-r  ]iiiirt  of  the  astragalus,  which  fit  into  corresponding 

dcpr^^wioiiH  in  the  libia,  and  receive  between  them  also  a  ridg« 

ill  Uic  middle  of  the  tibia.

The  next  bone  of  importance  belongins  to  the  hock  is  the  oi 
calcis,  which  corresponds  to  the  human  neel.  In  the  horse  it 
does  not  bear  any  weight,  but  receives  the  insertions  of  some 
important  tendons,  and  thus  acts  as  a  considerable  lever. 

The  other  bones  of  the  hock  are  placed  below  the  astragalus 
in  two  rows,  the  lower  of  which  rests  on  the  metatarsus.  These 
comparatively  small  bones  contribute  very  much  in  taking  off 
the  jar,  and  are  closely  bound  together  by  ligaments,  by  which 
all  motion  is  prevented. 

The  bones  below  the  hock  being  similar  to  those  below  the 
knee,  will  need  no  further  description.  They  are,  however, 
somewhat  longer  and  slighter  in  their  construction.  —  Ed.

THE   JOINTS. 


Tbe  chief  peculiarity  in  the  construction  of  joints  in  the  horse 
is  that  motion  is  almost  entirely  limited  to  one  direction,  and 
every  security  afforded  ogainst  lateral  movement;  the  result  of 
which  is  that  we  scarcely  ever  hear  of  dislocation  in  the  horse. 
Strength  and  speed  are  the  chief  objects  required,  and  accord- 
in|^y  we  find  that  the  joints  admit  of  a  great  extent  of  motion, 
but  in  one  direction  only.  We  have  before  observed  that  the 
ends  of  bones  forming  a  joint  are  tipped  with  cartilage,  which, 
being  elastic,  takes  on*  the  jar  from  the  bones.  This  cartilage 
is  lined  by  a  fine  membrane,  which  secretes  a  fluid,  somewhat 
resembling  the  white  of  an  egg,  by  which  means,  however  rapid 
or  violent  may  be  the  motion  of  the  animal,  the  part  b  yet 
eifectually  secured  from  friction.  This  fluid  is  prevented  from 
escaping  by  a  capsular  ligament,  which  is  strongly  attached  to  the 
oeignbounng  bones,  and  thus  surrounds  and  encloses  the  joint, 
being  however  sufficiently  loose  as  to  admit  the  requisite  motion. 
The  capsular  ligament  is  also  lined  internally  by  the  synovial 
membrane,  and  is  thus  secured  from  injury. 

Many  of  the  joints  of  the  horse  are  constructed  on  the  prin- 
ciple of  the  hinge  motion,  being  admitted  extensively  at  one  part 
and  limited  at  another. 

The  Shoulder  joint  is  formed  by  the  round  head  of  the  hu- 
merus fitting  into  a  socket  in  the  lower  part  of  the  scapula. 
This  socket,  however,  is  much  shallower  than  in  the  human 
Bobject,  there  being  no  lateral  motion  required.  Tlie  joint  has 
DO  ligaments  to  protect  it  with  the  exception  of  the  capsular ; 
but  this  office  ia  efiectually  performed  by  the  tendons  of  the 
strong  muscles  of  the  shoulder.

but  are  confined  behind.  Theite  joints  are  each  invested  by  a 
loose  cninular  liganunil,  which  permits  the  necessary  extensive 
tnoiion  »f  ihe  joint,  and  are  secured  on  each  side  by  strong 
lateral  lij^iunenis;  bi-i>ides  which  there  are  two  annular  bands, 
out'  behind  and  iliu  iitht-r  in  front,  which  serve  to  lie  down  and 
confine  tin-  fli-xur  ti'iidoni. 

The  /W/ocjt  Joint  is  formed  by  the  rounded  esitreniily  of  tbti 
caiiiton  approximating  with  the  concave  surface  aflbrded  by  tlte 
Iftrge  pattern  below,  and  (he  two  sesamoid  b»ni>s  behind.  It 
has,  in  addition  to  the  capsular,  no  Ivna  than  nine  ligaments, 
seven  of  which  are  connected  wilh  (he  sesamoid  bones,  and  thus 
serve  to  keep  ihcm  in  iheir  situation,  in  somewhat  the  same  man- 
ner as  the  masts  of  a  vessel  ace  secured  by  means  of  ttie  rigging 
ov  stays.  I'hc  other  two  ligaments  secure  the  joint  finiity  on 
either  side. 

The  I'aslfnt  joint  possesses  very  little  motion.  It  is  formed 
by  ihe  convex  extremity  of  the  Inrjie  fitting  into  corresponding 
concAviiies  in  the  Amnll  piisiern,  and  io  sectired  by  tlte  capsuUr 
and  two  liganicnts  on  each  side,  and  protected  by  tendons  both 
in  front  and  In-hind.

coffin  and  navicular  Xynw*  receiving  the  convex  exlrcniity  of 
tlie  small  pastern.  It  is  secured  by  a  capsular  and  three  pairs 
of  ligaments,  connecting  the  coffin  bone  wilh  lltcnnall  pnstem 
and  the  side  cartilages ;  and  four  other  ligaments,  two  ol  which 
peas  from  the  navicular  to  the  small  pastem,  one  joining  the 
navicular  to  the  coBin  bone,  and  another  to  the  flexor  smew. 
These  lijtaments,  however,  although  nunu^rous,  are  not  strong, 
as  the  joint  is  within  tlk-  cavity  of  the  hoof,  and  is  thereby  wal 
securco  from  injurjr.  "^ 


Joiutt  tftke  Hind  Extremibf. 

The  Hip  or  T%igh  joint  is  situated  so  deep-jeated,  and  so  well 

iirou-cted  by  large  muscles  and  tendons,  that  it  rwpiires  but  very 
i-w  ligaments.  It  is  as  before  observed,  a  ball  and  »ocket  joint, 
the  ball  being  formed  by  the  upiwr  part  of  the  femur  or  rhigh 
bone,  uiid  the  socket  (which  is  considerably  deeper  tlian  tlutt  of 


THE    HDBCULAR    SYSTEM.  37 

the  shoulder)  by  the  bones  of  the  pelvis.  The  socket  is  stilt 
furtber  deepened  by  ligamentous  aubsiauce  attached  to  its  rim. 
The  capsular  ligament  is  thin,  protection  being  afforded  by  the 
muscles ;  but  within  the  capsular  there  are  (unlike  other  joints) 
two  ligaments,  one  of  which  is  called  the  ligamenium  teres,  and 
is  of  great  strength.  It  passes  from  a  notch  in  the  ball  to  a 
similar  notch  in  the  socket,  whilst  another  portion  of  it  is  attached 
to  the  pubes.  This  ligament  greatly  assists  in  maintaining  the 
weight  of  the  limb  during  progression. 

The  Stxfie  joint,  which  corresponds  anatomically  to  the  human 
boee,  is  formedi  like  it,  by  the  apposition  of  the  femur,  the 
tibia,  and  the  patella.  Within  the  joint  we  find  two  moveable 
cartilages,  which  are  confined  to  the  tibia  by  several  ligaments, 
but  which  enable  them  to  slide  about,  and  thus  increase  the 
motion  of  the  joint  without  rendering  it  insecure.  The  patella 
is  a  small  bone  situated  in  front  of  the  joint,  which  it  protecis, 
being  bound  by  strong  ligamenu  to  the  tibia,  and  receiving  the 
attachments  of  the  tendons  of  the  strong  extensor  muscles  of  the 
leg,  thus  acting  as  a  pulley. 

Besides  those  mentioned,  there  is  a  strong  lateral  ligament  on 
each  side  of  the  joint,  attached  to  the  femur  and  the  tibia ;  and 
within  the  cavity  of  the  joint,  ligamentous  slips,  crossing  each 
otber,  are  attached  to  the  middle  of  these  two  bones. 

The  i/bcA  joint,  like  the  stifle,  is  well  furnished  with  liga- 
ments; and  it  has  no  less  than  six  separate  articulations,  the 
principal  of  which,  however,  is  that  between  the  tibia  and  astra- 
galus, to  which  bones  the  whole  motion  of  the  joint  is  confined. 
There  are  two  strong  ligaments  on  each  side,  both  of  which  pro- 
oeed  from  the  tibia,  and  pass,  one  to  the  astragalus,  and  the 
other  to  the  os  calcis,  and  expand  on  the  other  bones.  There 
are  other  ligaments  attaching  the  astragalus  to  the  metatarsal 
bones.  The  os  calcis  is  bound  by  ligaments  to  the  astragalus,  the 
tibia,  and  metacarpal  bones;  and  each  articulation  possesses  sepa- 
rately its  capsular  ligament. 

The  joints  below  the  hock  in  the  hind  leg  correspond  with 
those  in  the  fore  extremity.  Having  much  less  weight  to  sustain, 
tbey  are  less  exposed  to  concussion,  and  more  rarely  become  dis- 
eased. —  Ed.

four  belong  to  the  tongue,  five  to  the  pharynx,  seven  to  tlie 


larynx,  and  two  to  the  palate. 


i'he  muscles  ol'tlte  jf'runA,  one  hundred  and  thirteen  in  number,

size  and  length,  extending  on  each  side  of  the  dorsal  spine 
almost  the  whole  length  of  the  back,  of  which  it  forms  the  prin- 
cipal strength;  it  is  particularly  observable  in  stout  neaby 
horses. 

The  seventh  region  of  the  thorax  is  composed  of  one  muscle^ 
tltc  iiiaphra(/m,  which  separates  the  thorax  from  the  abdomeo, 
and  is  tlie  principal  agent  in  respiration,  acting  inde])endentljr

the  line.4,  or  railicr  the  furrnuK,  of  deniarcution  are  readily  per- 
ceptible. It  i.i  nt?edle«u  to  observe,  that  tht-^e  nitucles  form  the 
erealer  part  of  a  haunch  of  veniHiii,  and  in  deer  are  .more 
Jnrgi'ly  developed  than  in  slieep. 

There  are  four  smaller  mnsclev,  atiachi-d  below  to  tlie  upper 

Earl  of  lite  thigh  bune,  and  above  to  the  under  {mris  of  the 
Atmch  bone,  their  office  being  to  ii«i)it  in  the  extension  of  the 
haunch,  and,  in  some  measure,  lo  rotate  it:  some  of  them  are 
■ilnated  within  the  ]M*lvit^  and  arc  connected  niih  tlie  peri- 
toneum. 

There  are  Uirec  miacles  whtch  form  the  front  p«rt  of  tlie 
haunch.  One  rises  from  the  spine  of  the  ilium,  die  hip  boiiey 
and  i»  inserted  into  the  membranous  covering  of  the  muscles  of 
the  thigh,  whence  it  in  ailled  the  teiuor  vvtgina,  and  ia  very 
perceptible  in  poor  horaes. 

Another  larj^e  muscle  is  attached  to  the  ilitiin  above  and 
patella  below,  and  19  called  the  retfuM. 

The  third  muscle  is  of  great  size,  and  has  tliree  divisions, 
which  are  often  considei-ed  as  separate  muscles.  Each  of  these 
heads  are  inserted  into  the  patella  below,  but  abot-e,  two  are 
attactwd  lo  ihc  femur,  and  one  to  tlie  bones  of  the  pelvis. 

Tlu'se  powerful  niiisctes  although  not  attached  to  the  tibia 
itself,  are  yet  connected  with  it  by  na-ans  of  t)»p  patella,  and 
thus  become  powerful  exlcnwrs  of  the  thigh,  raising  and  ad- 
vancing i)h-  limb,  nnd  ntfiming  in  llie  progression  of  tlw  liaunch. 


THE   MUSCULAA   SYSTEM.  41 

On  tbe  inside  of  the  iliigh,  forminf;  that  fleshy  prominence  so 
perceptible  in  muscular  norses,  and  which  often  causes  the 
thighs  to  touch  each  other,  we  find  four  muscles.  The  first  is 
a  long  slender  muscle,  attached  above  to  the  lumbar  vertebree 
and  the  bones  of  the  pelvis,  and  below  to  the  lower  part  of  the 
femur  and  upper  and  inner  part  of  the  tibia.  It  assists  in  bend- 
ing the  leg  inwards,  and  is  called  the  sartorius,  which  signifies  a 
tailor,  being  supposed  to  be  greatly  employed  by  tailors  when 
sitting  cross-l^^ed  on  a  board.  A  thin  broad  muscle,  super- 
ficially placed,  is  attached  above  to  the  pubes,  and  below  to  the 
former  muscle. 

A  third  muscle,  short  and  thick,  is  attached  to  the  pubes  above, 
and  the  femur  below ;  and  the  fourth  is  a  double  muscle,  attached 
also  above  to  (he  pubes  and  below  to  the  femur. 

The  fifth  is  a  powerful  muscle,  attached  above  to  the  bones  of 
the  sacrum,  and  the  ischium,  and  below  to  the  lower  and  inner 
part  of  the  femur,  and  upper  and  inner  part  of  the  tibia. 

The  outer  part  of  the  haunch  is  formed  by  two  double  muscles; 
one  is  denominated  the  biceps,  and  is  attached  above  to  the 
sacrum,  the  bones  of  the  tail,  and  the  ischium ;  and  below,  one 
portion  to  the  patella,  and  the  other  to  the  upper  part  of  the 
tibia.  This  large  muscle  is  particularly  conspicuous  in  thorough- 
bred horses,  and  forms  the  outermost  part  of  the  quarter.  Its 
large  development  is  deservedly  admired,  and  is  justly  considered 
a  sisD  of  breed. 

Tne  other  muscle  is  situated  behind  the  former,  forming  the 
most  posterior  part  of  the  quarter ;  it  is  well  developed,  and  ex- 
ternally perceptible ;  and  tne  space  between  it  and  the  former 
muscle  is  denominated  the  poor  mark,  being,  of  course,  well 
marked  in  lean  horses,  and  imperceptible  in  fat  ones :  it  is 
attached  above  to  the  same  bones  as  the  former  muscle,  and 
below  to  the  upper,  anterior,  and  inner  part  of  the  tibia.  These 
muscles  raise  Uie  limb  and  abduct  it. 

The  muscles  of  the  thigb  and  leg  are  divided  into  three  regions, 
one  in  fix>nt,  and  two  behind.  The  anterior  is  occupied  by  three 
muscles,  two  of  which  extend  the  foot,  and  at  the  same  time  Ilex 
the  hock.  The  first  is  attached  above  to  the  femur,  becomes 
tendinous  above  the  hock,  where  it  passes  through  a  sheath,  and 
takes  its  course  in  front  of  the  shank  and  the  pasterns,  and  is  in- 
serted into  the  front  part  of  the  coffin  bone.  The  second  muscle 
lises  from  the  fibula,  and  joins  the  former  below  the  hock.  The 
third  is  attached  above  to  both  the  femur  and  the  tibia,  and 
below,  after  passing  through  a  sheath  in  front  of  the  hock,  to 
both  the  cannon  and  the  inner  splint  bone. 

The  two  regions  behind  the  tibia  are  distinguished  as  the 
snperficial  and  the  deep-seated :  ihe  former  is  occupied  by  three 
jniucles,  the  first  of  which  is  attached  above  to  the  lower  part  of

fibiilii,  jiik)  irif<.-riorly  to  t)>c  os  calcis. 

Th**  iltiyt-frated  rrgion  is  also  composnl  of  three  muscles.  Tbe 
first  it  short  mid  thick,  and  is  atlachcd  above  to  tbe  outer  and 
bnck  ptm  of  the  Ivtnur  and  tbe  cnpsiilar  ligament,  and  lakine  an 
obli(|nf  direction  to  the  upper  and  inner  part  of  tbe  tibia.  1  bus 
tituatcd,  it  rotates  in  some  measure  the  stifle-joint. 

Tbe  next  muscle,  the  flexor  p<-difi,  is  attached  above  to  tbe 
outer  and  back  part  of  the  tibia  and  tbe  fibula ;  becomes  tendinous 
just  above  tbe  bock,  wheru  it  passes  through  a  sbeaili,  in  a 
groove  on  tbe  inn<T  side  of  tbe  os  calcis,  and  below  tbe  bock  i« 
denomiiintcd  tltc  flexor  perforans,  having  a  similar  destination  to 
the  »aaw  tendon  in  tin*  fore  extremity. 

The  third  miMcIc  rises  front  tbe  outer  and  back  pan  of  the 
tibia,  becomes  tcn<liiious  somewhat  above  the  hock,  on  the  inside 
of  which  it  paMW  tlirougb  a  shcatb,  an<)  joins  tbe  former  tendon 
below. 

For  a  more  [xirtictilur  account  of  tbe  mu»cle«,  the  student  is 
referred  to  Mr.  IVrcivall's  excellent  work  "  Oti  the  Anatomy  of 
the  Horse;"  and  also  to  Mr.  Blaine's  "  Outlines  of  tbe  Veteri- 
nary Art." 

'i'lie  muscles  are  abundantly  supplied  with  blood  by  the  blood- 
TOMels,  which  renders  titoir  colour  dark.  Tlie  depth  of  their  bue 
b  norc  or  les»  in  proportion  as  they  are  exercised,  and  thus  in 
the  horse  ihcj'  are  darker  than  in  the  ox  or  sbeep.  Tliey  are 
idsQ  placed  to  greater  mechanical  advaniage,  the  joints  admitting 
more  extent  of  motion  tlian  in  these  weaker  animals.  Besides 
wliieb  they  arc  m««'  abundantly  >iupplic<l  with  nervous  energy 
by  incaiu  of  tlie  nervi"!!,  t«  which,  more  than  to  any  thing  else,  is 
owing  tbe  untiring  energy  which  a  well-bred  horse  so  often  dis- 
play*. 

The  muscles  are  susccpttble  of  ureat  alteration  by  me«ns  of 
training,  tbe  object  of  which  is  to  obuiin  ibe  gr<.«test  possible 
strength  in  the  smallest  possible  compass.  'lo  effect  this  pur*

circumstance,  farriers,  mistaking  the  cause  for  the  effect,  have

CHAP.  IX. 

ON    THE    BRAIN    AND    NERVES. 

The  brain,  the  seat  of  the  mind,  and  the  fountain  of  sensation, 
19  a  soft  body,  situated  in  a  cavity  of  the  skuU  called  the  cranium. 
In  man  it  occupies  by  far  the  greater  portion  of  the  skull ;  but, 
in  the  horse,  from  its  much  smaller  size,  and  from  the  large  space 
devoted  to  the  face,  the  cranium  is  much  the  smaller  part.  It 
mually  weighs  about  one  pound  and  a  few  ounces  in  the  horse. 
It  is  closely  invested  by  a  membrane,  called  the  pia  mattr,  whilst 
the  cranium  is  lined  by  a  firm,  strong  membrane,  called  the  dura 
mater.  Between  these  there  is  another  delicate  membrane,  called 
the  tvmea  arachnoides. 

The  dura  mater,  by  its  duplications,  fornis  several  processes  and 
sinuses,  the  former,  by  descending  between  its  divisions,  serve  to 
secure  the  brain  in  its  position,  and  the  latter  act  as  reservoirs 
for  the  venous  blood,  thus  preventing  ihe  brain  from  being 
injured  by  any  temporary  impediment  to  its  passage. 

The  pia  mater  closely  embraces  the  brain,  and  dips  into  its 
conTolutions.  The  brain  consists  of  three  parts,  the  Cerebrum^ 
the  CenAeUmttt  and  the  Medulla  oblongata. 

The  Cerdfrtcm  is  considerably  the  largest,  and  is  divided  into 
two  hemispheres,  each  of  which  closely  corresponds  with  its  fellow. 

On  cutting  into  the  cerebrum,  we  find  that  it  consists  of  two 
portions,  —  the  medullary,  or  white ;  and  the  grey,  or  cortical  part. 
The  latter  is  mostly  situated  towards  the  surface,  and  the  former 
towards  the  centre;  but  both  appear  to  run  into  each  other. 
Within  the  hemispheres  there  appear  to  be  various  cavities, 
canals,  and  membranes,  which,  in  this  work,  it  is  unnecessary  to 
describe. 

The  CerAellttm,  or  little  brain,  is  situated  behind  the  cerebrum, 
than  which  it  is  considerably  smaller.  It  appears  to  consist  of 
medullary  and  cortical  substance  mingled  together. 

The  Meduila  oblongata,  the  smallest  division,  is  situated  at  the 
base  of  the  brain.  It  is  medullary  in  its  structure,  and  gives 
origin  to  the  greater  part  of  the  cranial  nerves.  It  is  by  far  tha 
most  sensible  part  of  the  brain,  for  whilst  portions  of  the  cerebrum 
have  been  cut  away,  in  some  animals,  without  giving  any  apparent

I'he  spinal  marrow  nixv  be  conjtidered  ai  the  continuation 
of  die  brain,  running  from  the  nuHliillii  oblongata,  throiiglmut 
the  spinal  catial,  to  the  lAil.  It  ia  enveloped  hy  the  tuime  mrtn- 
branea  ta  ibe  hrain,  and  oonliniie»  to  the  sacrum,  wliei-e  it  rndg 
in  several  nervoti»  cords.  Its  form  in  cylindrical,  and  it  hufi  bv«n 
found  to  consist  of  six  bands,  in  the  eenii-e  of  wliidi  iliere  ta  s 
sort  of  canal. 

Tlie  Sfrvet,  arising  from  the  brain  and  spinal  con),  are  forty 
six  pair,  ten  of  which  proceed  from  tite  bruin,  and  the  remainder 
from  the  cord,  and  are  therefore  called  the  »pinal  nerves. 

On  examining  a  nerve,  we  find  i)iiit  it  consiits  of  a  vast  number 
of  white  fiUimentt,  each  having  iis  particular  covering,  and  yet 
conipactly  bound  togeiliei-,  and  inveited  by  iiienibraiie. 

Of  the  Cranial  nerves,  the  first  pair  is  ilie  Olfnctory,  the  nerve 
of  smelling,  pulpy  in  its  structure,  and  the  largest  in  the  bo<)y. 
It  rises  from  llic  cerebrum,  passes  ottt  of  tlie  cranium,  and  a 
spread  out  on  the  membrane  lining  the  nostrils. 

The  second  pair  is  the  Outic,  which  rises  frum  tlte  cerebrum, 
but  before  they  pass  out  of  the  skull  join  together,  and  decuiisate, 
the  right  nerve  going  to  the  left  eye,  and  vift  vmd.  It  laket  ait 
oblicjuc  course,  pierces  the  outer  coals  of  the  eye,  and  is  sprrad 
out  in  the  form  of  the  retina,  and  thu«  conveys  tIte  impressions 
of  objects  to  the  brain.  The  sense  of  hearing  is  supplied  by  n 
soft  tierce,  tlie  auditory,  which  enters  nn  orifice  in  the  temporal 
bone,  where  the  scat  of  hearing  is  contained.  The  sente  of  taste 
is  supplied  by  the  fifth,  which  is  a  compound  nerve,  conveying 
both  sensation  and  motion.  The  other  cranial  nerves  cunvc}' 
sensation  and  motion  to  the  various  parts  of  tlie  head;  but  tliere 
18  one  nerve  which  demands  more  particular  notice.  This  is  the 
par  voffvm,  or  pnrumo-fftutrie,  of  the  French,  It  rises  from  the 
brain,  posses  down  the  neck  close  to  the  carotid  artery,  and 
distributes  branches  to  Uie  pharynx,  larynx  and  (r^ophagus,  lieart, 
lungs,  stomach,  and  liver.  If  divided  oa  both  sides  in  the  living 
animal,  death  immediately  rnsuee.  Its  importance  may  thus  bo 
readily  conceived;  it  is  intimately  connected  with  life  itself, 
giving  to  the  heart  and  stomach  its  power  of  motion,  indepetidwt 
of  the  will. 

'Pic  Spinal  arc  compound  nerves,  having  a  double  function, 
and  a  twofold  origin,  cnnvrying  l)olh  sensation  and  motion.

This  latter  is  the  nerve  of  sensation,  the  other  the  nerve  of 
motion ;  and  thus,  though  united  together,  the  filaments  are  yet 
distinct,  and  a  part  is  endowed  mostly  with  sensation,  or  with 
motion,  accordine  as  the  filaments  of  the  former  or  the  latter 
predominate.  There  is  one  other  nerve  that  remains  to  be 
noticed;  it  has  heen  called  the  Gangliai,  and  also  the  Sympa- 
Oietie.  "  It  belongs,"  observes  Mr.  Youatt,  in  his  admirable  lec- 
tures, "  neither  to  the  cerebral  nor  the  spinal  system,  and  seems, 
in  its  liinction,  to  be  independent  of  both.  At  the  base  of  the 
cranium,  and  in  front  of  the  atlas,  I  find  a  pyriform  reddish  body, 
which  gradually  contracts,  and  terminates  in  a  nerve.  I  inquire 
not  now  into  the  origin  of  this  ganglion,  but  a  superficial  glance 
at  the  nerve  tells  me  that  it  is  peiforming  some  important  office. 
It  is  connecting  itself  with  the  cerebro^spinal,  and  with  every 
cervical  nerve;  but,  more  particularly,  it  is  forming  complicated 

f>lexuses  on  every  neighbouring  blood-vessel.  I  trace  it  particu- 
arly  on  both  the  external  and  the  internal  carotid,  and  I  follow 
it  in  the  subdivisions  of  these  vessels,  until,  from  the  minuteness 
of  the  vessel,  and  the  pulpiness  of  the  nerve,  it  eludes  my  sight. 
Hereafter  I  shall  have  to  trace  the  course  of  the  nerve  in  the 
thorax,  forming,  with  the  cerebro-viscei-al,  a  plexus,  or  rather, 
an  investing  membrane,  around  every  vessel  of  the  heart  and 
lungs;  and  then,  having  reached  the  abdomen,  and  combining 
in  the  semilunar  ganglion  its  own  influence  with  that  of  the 
cerebro- visceral  and  the  phrenic,  it  becomes  the  seat  or  centre 
of  organic  nervous  power,  diffusing  its  radiations  over  every  ar- 
tery and  absorbent,  and  gland,  and  ganglion  ;  every  thing  con- 
nected with  secretion,  nutrition,  and  life ;  itself  the  very  principle 
of  life  and  action — the  soul  of  the  organic  system.  It  was 
termed,  before  its  character  and  power  were  suspected,  the  sym- 
pathetic nerve,  because  it  seemed  to  connect  the  whole  system 
t<^ether:  it  is  denominated  by  others  the  gangliai  nerve,  from 
its  supposed  origin,  either  in  the  superior  cervical  or  the  semi- 
lunar ganglion ;  but  it  would  more  properly  be  designated  the 
ffreat  organic  nerm,  —  the  secretory,  nutritive,  chemical, — while 
the  cerebro- visceral  is  the  motor  organic  nerve.  It  is  the  power 
which  presides  over,  and  effects  the  changes  in  that  fluid  which 
the  motor  nerve  keeps  in  circulation."  —  Ed.

the  spine,  by  menus  of  a  dciiible  joint,  affords  to  llie  ribs  a  motion 
backwards  and  forwards,  by  which  means  the  cavity  of  the  cliest 
is  enlarged  or  diminisiiL'd.  This  moiion,  Il0we^•er,  it  consi* 
derably  less  in  C[uadriipeds  than  in  man,  for  in  the  laUer  the 
rising  and  falling  of  (he  clK^)lt  is  tccn  in  common  respiration, 
whiUt  in  Uu-  former  it  is  not  pi-rceived,  iial<-ss  the  brothing  be 
embarrassed.  The  ribs  are  connected  topelher  by  fleshy  siib> 
stance,  Irrmed  the  intercostal  muscles,  which  are  disputed  in  an 
oblique  coui-w,  by  which  means  their  length  considerably  exceeds 
(bat  of  the  space  between  one  rib  and  another,  so  that  a  con- 
traction of  one  third  their  length  will  bring  the  ribs  togeilter, 
which  could  not  be  the  case  if  tlie  muscles  took  the  shortest 
cotii'te  from  one  rib  to  another. 

The  chest  is  Bepnrated  from  the  abdomen  or  belly  by  a  very 
singular  and  important  mu^clci  called  i\K  Dinphrat/m,  or  midriff, 
which  is  convex  towards  the  chest  when  in  n  state  of  rest.  This 
miitcle  is  sitapcd  somewhat  like  a  fan,  and  is  attach«'d  to  iha 
inferior  extremities  of  the  ribs  and  to  the  spine,  by  which  meaiis 
its  position  is  rendered  oblique,  and  its  development  more  ex- 
tended, and  its  action  greater  than  it  would  otlierwiM'  have  been. 
'I'iie  diaphragm,  unlike  every  other  muscle,  is  fleshy  at  its  circum- 
fen-nce  and  tendinous  at  its  centre.  The  reason  of  (his  peculiar 
construction  may  be  thus  explaineiL  The  ccntml  part  of  the  dio* 
pbraginis  pierced  witli  two  holes  for  (lie|>atsageof  ihecesophngos, 
tlie  tube  which  conveys  food  to  (he  slomach,  and  the  vein 
which  conveys  the  blood  to  the  liver  for  the  secretion  of  bile. 
Now,  if  these  important  vessels  were  Burrounded  with  muscular 
suUstance,  they  would  be  forcibly  coinprc'B«-d  eviTy  time  the 
diaphragm  contracted,  and  would,  in  consequence,  be  liable  to

considerable  injury;  but  being  eurrounded  with  tendinous  sub- 
stance which  possesses  no  such  power  of  contraction,  all  danger  of 
compreasioQ  is  at  once  removed,  without  any  sacrifice  of  strength 
or  power  in  the  muscle.  The  diaphragm,  when  in  a  quiescent 
state,  is  convex  towards  the  chest ;  and  when  in  action,  it  becomes 
flat,  thus  enlarging  the  cavity  of  the  chest. 

The  thorax  is  everywhere  lined  internally  by  a  thin  serous 
membrane,  which  secretes  a  fluid,  by  which  the  surface  of  the 
cavity  is  lubricated,  and  its  contents  are  enabled  to  glide  upon 
each  other  without  occasioning  any  friction  or  inconvenience. 
This  membrane  is  called  the  pUura,  and  the  portion  which 
lines  tlie  chest  itself  is  designated  the  pleura  costalis,  while  that 
which  covers  the  lungs  is  distinguished  as  the  pleura  pulmonalis. 
This  membrane  divides  the  chest  into  three  cavities,  one  on  the 
right  side,  containing  tlie  right  lung,  and  the  other  two  on  the 
]en  side,  the  smaller  of  which  contains  the  heart,  and  the  larger 
the  left  lung. 

The  rigM  lung  is  thus  the  largest,  and  consists  of  three  lobes 
or  divisions,  whilst  the  left  lung  only  contains  two.  These 
divisions  of  the  chest  do  not  communicate  with  each  other,  so 
that  if  one  cavity  is  injured,  or  air  is  admitted  into  it,  respir- 
aljoD  can  be  carried  on  in  the  other. 

The  windpipe,  or  trunk  of  the  lungs,  is  composed  of  cartilages 
or  cartilaginous  rings,  joined  together  by  a  slrong  and  elastic 
membrane.  The  cartilaginous  rings  are  strong  and  thiclt  in  the 
front  part  of  the  windpipe,  but  gradually  become  thinner,  and 
terminate  in  thin  slips,  or  mere  membranes,  which  pass  over 
each  other,  instead  of  meeting  end  to  end.  By  this  contrivance 
the  windpipe  will  admit  of  being  compressed  considerably,  by  the 
ends  passing  over  each  other;  but  such  is  the  elasticity  of  the 
cartilage,  that  the  moment  the  pressure  is  removed,  the  windpipe 
returns  to  its  original  form.  1'he  use  of  the  elastic  membranes 
which  unite  the  cartilaginous  rings,  is  to  admit  of  the  variou* 
motions  of  the  windpipe,  especially  that  of  its  being  elongated ; 
and  so  great  is  their  strength,  that  we  never  in  any  accident  find 
it  torn,  or  the  cartilaginous  rings  separated  from  each  other. 

Tbe  windpipe,  on  entering  the  chest  between  the  6rst  pair  of 
ribs  separates  into  two  parts,  one  going  to  tlie  right,  and  the  other 
to  the  left  lung ;  from  these  divisions  numerous  branches,  called 
the  bronchi,  proceed  to  every  pan  of  the  lungs,  dividing  and  sub- 
dividing, and  diminishing  in  their  course.  These  ramifications 
graduuly  lose  their  cartilaginous  cliaracter,  and  at  length  ter- 
minate in  an  immense  number  of  diminutive  air  cells. 

The  lungs  themselves,  therefore,  are  composed  of  the  air  cells, 
the  bronchi  connected  with  iliem,  and  an  iiifiuite  number  of 
arteries,  veins,  and  absorbent  vessels,  the  whole  being  connected 
together  by  cellular  membrane,  thus  forming  these  light  spongy,

but  the  m\v»  of  ihe  lower  recede  to  as  to  form  a  triangular  spacr, 
which  is  occupi<-(i  by  a  ligament. 

The  Cricoid,  or  ring-like  cartilage,  is  placed  {>elow  ih«  thyroid. 
lits  anterior  portion  resembles  a  ring  of  tlie  wind-pipe,  but  its 
'  back   part  is   considerably  broader,  so  that  it  overIa|io  tlui  lint

'I'hc  two  Ariftenoid,  or  ewer-shaped  cartilage»,  are  much  smaller 

fthan  tlw  other,  and  arc  placed  at  the  upper  part  of  the  larynx, 

itnmodiiiiely  adjoining  the  back  part  of  the  cricoid ;  thus  platted, 

thexv  tri.iiigiilitr  bodies  leave  an  aperture  between  them,  which 

form!!    thi-    entrance    to    the   windpipe,   and  their  margins    are 

covt'red  by  a  membrane,  which  forms  what  is  called  the  Ilimti-

L«fficc,  which  consists  of  shutting  down  upon  the  glottis  like  liii^ 

'  lid  of  a  lea-pot,  to  which,  from  its  heart-iike  shape,  it  i*  nd* 

mirably  adapted.     Viewing  this  cartilage  in  ils  usual   position, 

jrWe  lintl  that  its  surface  nearest  the  larynx  h  smooth  atid  toin^-

The  larynx  is  lined  throughout  ils  internal  sur^ce  hy  a  fiiio 
delicate  incinhrane,  which  secretes  a  mucus  for  iiit  protection. 
It  is  also  abundantly  supplied  with  nerves,  by  which  it  is  rcn* 
dered  [x-culiarly  sensible,  and  in  this  resjiect  greatly  differs  from 
the  membrane  lining  the  windpi[>e;  for  whiUt  the  latter  may  be

arises  from  some  irritation  of  this  port.

It  is  lined  throughout  by  a  mucous  membrane  called  the  Schneid- 
erian  or  pituitary  membrane,  on  which  is  spread  out  the  nerve  of 
emell  as  well  as  one  of  feeling.  The  cavity  is  divided  by  a  thick 
cartilage,  called  the  septem  nasi,  which  is  fixed  in  front  to  the 
nasal,  and  behind  to  the  maxillary  bones.  This  cartilage  is  also 
covered  by  the  membrane  before  apokeu  of;  which,  when  inflamed, 
as  in  coltu,  becomes  very  red,  and  in  glanders,  is  often  the  seat 
of  ulcers. 

The  nostrils  communicate  with  the  sinuses  of  the  head,  and 
above  with  the  larynx. 

The  entrance  to  the  nostrils  is  formed  by  what  is  called  the 
&lse  nostrils,  which  is  formed  by  the  skin,  and  possesses  consider- 
able flexibility,  particularly  in  well  bred  horses,  in  whom  the 
opening  to  the  nostrils  is  much  larger  than  in  coarse^bred  animals. 
The  false  nostrils  form  a  sort  of  cavity,  which  has  no  opening  at 
the  upper  part,  and  this  circumstance  gives  them  their  name. 

The  Heart 

Is  a  strong  hollow  muscle,  of  a  conical  shape,  with  its  base 
towards  the  spine)  and  its  apex  towards  the  lefl  side,  against 
which  it  is  thrown  at  every  contraction.  It  is  double,  hav- 
ing a  right  and  a  left  side,  the  former  containing  black,  and 
the  latter  red,  blood;  the  right  side  is  the  thinnest  and 
weakest,  being  devoted  to  the  lesser  office  of  the  circulation  of 
the  hmgs ;  tlie  left,  the  stoutest,  having  to  govern  the  general 
circulation  of  the  system.  Each  of  these  halves  consists  of  two 
cavities,  an  auricle  and  a  verOricIe  ;  the  former,  which  derives  its 
name  from  its  resemblance  to  a  dog's  ear,  is  considerably  thinner 
tban  the  latter,  and  is  situated  towards  the  base.  The  heart  is 
formed  principally  of  fleshy  fibres,  connected  together  by  cellular 
tissue,  whence  it  obtains  its  elasticity;  and  its  surfaces,  both  in- 
ternal and  external,  are  lined  by  a  fine  transparent  membrane. 
The  blood  is  prevented  from  moving  in  a  retrograde  course  by 
means  of  a  number  of  valves :  there  are  three  in  the  left 
ventricle,  the  edges  of  which  are  connected  by  tendinous  cords 
(cords  tendines)  to  small  fleshy  eminences  on  the  inside  of  the' 
ventricle,  called  cameffi  columnee  or  fleshy  columns.  These 
tendinous  cords  are  more  numerous  in  the  valves  of  the  left  ven- 
tricle than  in  the  other  parts,  and  being  supposed  with  the  valves 
to  resemble  a  mitre,  are  named  mitral  valves.  Tliere  are  valves 
also  in  the  right  ventricle  for  a  similar  purpose,  which  are  named 
tricuspid,  or  three-pointed ;  also  in  the  great  artery,  or  aorta, 
and  in  the  pulmonary  artery,  where,  having  no  cords,  and 
resembling,  or  supposed  to  do  so,  a  half  moon,  they  are  named 
semilunar. 

The  heart  is  enclosed  in  a  strong  membranous  bag,  which  is

ON    THE    anCCLATION    OF   THE   BLOOD. 

[Tiir  right  side  of  the  heart,  we  liave  said,  is  devoled  to  the  pu 
inoniiry  circitlalion  ;  its  auricle  receives  from  a  large  rein,  calM 
thu  vena  cava,  the  blood  which  liiu  travelled  thi'onghout  the 
syftetn,  whence  it  pat^ses,  liy  the  action  of  the  licnrl  into  the 
right  ventricle,  which,  by  its  conlrac[ion>  forces  it  iiilo  a  lar^ 
Tenel,  called  the  pulmonary  artery. 

'Iliciice  (he  blood  is  sent  into  the  lunf^  and  ramifies  ihrouj^h- 
out  its  minute  veiiseU.  where  it  is  expoaetl  to  the  action  of  the 
inspired  air,  and  becomes,  by  means  we  nliaJl  afterwards  speak 
of",  reddened  ami  pmilied.  This  process  bcin^;  accomplished,  the 
blood  pn«ses  into  niinuie  veins,  which,  coalt-Minif,  b<.-<;ume  the 
pulmonary  veins  (in  the  hor»e  eight  in  number),  anil  through  them 
the  blood  again  returiiK  to  the  lieArt.  So  much  for  the  pul* 
monary  circulation. 

The  left  auricle,  receiving  the  purified  hloo<l  from  the  puU 
monar)'  veins,  forces  it  into  llic  left  ventricle,  which,  contracting, 
Bends  the  vital  fluid  into  a  large  strong  vessel,  called  the  aorta, 
whence  it  possn  into  smaller  arteries,  to  he  distributed  through- 
out the  whole  system.  The  remote  divisions  of  the  arteries  arc 
called  the  nipillury  vessels,  and  in  them  the  blood,  afler  having 
Hccomplislieil  its  purposes  and  conveyed  nouri^hmeiil  to  all 
parts,  becomi'«  black  and  impure,  and  in  this  state  enters  the 
capillaiy  veitu:  which,  conjoining  and  increasing  in  siie,  and 
diminishing  in  number,  convey  the  blood  again  to  the  right 
auricle  of  the  heart.  Just  before  il  enters  the  heart,  it  receives 
a  supply  of  a  milky  Huid,  chilled  chv!e,  wliich  is  extracted  from 
the  Ibod,  absorbed  by  certain  ^niall  vessels,  called  lacteals,  and 
conveyed  by  a  specific  cliannel  into  the  vena  cava.  Sucli.  llten, 
is  the  circle,  or  rather  the  double  circle,  which  the  blood  takes, 
and  by  which  so  many  important  purposes  are  beautifully  and 
correctly  accomplished. 

The  circulation  of  the  blood  is  accoiDfJished   by  the  joint

I  tlifTerent  cavities,  could  not  be  correctly  performedi  unless  some 

provision  were  made  for  preventing  llie  blood,  when  the  ventricles 

conlraci,  from  retroprading  into  the  auricles.     This,  however,  is 

I  clfecti-d  bv  means  of  a  valve,   situated   between    these  cavities, 

rhich  is  formed  by  a  duplication  of  the  inner  membrane  of  the 

*art,  thickened  by  fibrous  substance.     The  floating  edges  of 

btliis  valve  in  the  right  ventricle  presents  three  points,  and  in  the 

^left  two ;  whence  the  former  is  called  the  tricuspid,  and  the  latter 

the  mitral.     The  edges  of  each  valve  is  joined  by  numerous  short 

tendons  to  the  fleshy  columnii  of  the  heart ;  ami  whilnt  the  blood 

is  flowing  into  the  ventricles,  the  fleshy  colunins  are  passive: 

[but  wlien  itte  veniriciei  act,  iheie  columns  also  contract  and 

]raw  tlie  edges  of  the  valve  together,  and  thus  closex  the  cavity 

I  that  direction,  and  prevents  the  blood  re-entering  the  auricle. 

There  are  also  valves  that  guard  the  enlrnnce  of  the  »aria,  and 

pulmonaiy  arteries ;  but  they  arcof  a  difTereut  dtscription,  being 

>r  less  strenpfth,  because  they  are  nut  called  upon  to  opi>oae  the 

awerful  action  of  the  ventricles.     Accordingly,  we  find  they 

nsist  of  three  foUls  of  membrane,  aiid  are  called  from  their 

ttmilututr.     'Iliey  are  so  situated,  that  when  the  blood 

cs  into  the  arlerlen  they  are  thrown  against  their  sides,  and 

flten  the  blood  liaM  posM-d,  they  are  thrown  up,  so  that  their 

meet,  and  thus  prevent  the  bluud  ivturning  to  the  heart. 

Iq  fialies,  llie  heart  is  single,  and  only  serves  the  ot^ce  of  the 

pulmonary  circulation,  tlutt  of  the  system  being  accomplished  by 

iie  arteries  alone;  in  the  hone,  tliough  the  heart  is  the  principal 

awer,  yet  the  arterirt  greatly  oiMux,     The  Aurla,  which  receives 

blood  from  the  left  ventricle,  divides  into  two  branches,  called 

Antrrior  and  Pailtrior    Aorta  ;    the  former  conveying    llie 

u<l  to  the  lieiiil  and  iM-ck,  and  the  latter  to  the  lower  )karts  of 

body.     Tlii-M.'  arteries  are  strong  and  thick,  and  consist  of

part  of  the  body,  where  an  artery  is  sufficiently  near  the  surfiuie  of 
the  skin  to  l>e  perceptible. 

The  arterie*,  however,  do  not  all  possess  an  equal  thickness 
and  power;  for  instance,  the  pulmonary  artery,  lhouf{h  quite  as 
]arge  as  the  aorta,  is  neither  so  iliick  nor  so  strong :  and  the  reason 
is,  that  the  «ame  power  is  not  required  to  send  tlie  blood  over 
the  unnller  circuit  itf  the  lungs  as  over  the  larger  one  of  the 
whole  tyttcm,  and  for  the  lame  reason,  tlie  right  udff  of  the  heart 
U  weaker  than  the  left.

time ;  and  all  these  various  offices  are  perrorm<-<i  not  only  by  the 
same  class  of  vessels,  but  by  the  same  fluid,  the  blooil. 

Having  secoiiiplislii'd  llicse  iiuporlant  purpoies,  the  capillary 
itrieries  terminate  in  equaily  minute  vewns,  called  the  capillary 
veins,  and  so  abundant  are  these  diminutive  vessels,  that  the 
finest  point  of  the  finest  needle  cannot  be  plunged  into  the  body 
without  iiem-irnting  jconie  of  them.  By  the  time  the  blood 
reaches  the  veins,  it  become*  dark  and  tmpui-e,  and  loaded  with 
carbon;  the  ofRet-  of  the  veins,  therefore,  is  to  return  it  to  the 
heart  to  Ite  ag^iin  purified.  'I'lie  circulation,  howevei',  becomes 
much  slower,  m  it  is  further  removed  from  the  impulsive  power 
of  the  Itearl ;  nm!  the  veins,  which  are  supposed  to  contain 
two  thirds  of  ihe  whole  blno<l  circulating  in  the  system,  are 
consequently  much  more  numerous  than  the  arteries.  They  do 
not,  however,  pojsess  the  same  strength  in  their  coats  ax  the 
arteries,  nor  hiive  they  any  ptdsaiing  power,  'Hiey  have,  how- 
ever,  the  imistancr  of  oilier  agents  in  propelling  (he  blood 
to  it*  detiti nation.  The  greater  number  ol  ihem  possess  valves, 
which  admit  llie  blood  lo  pass  in  one  direelton.  but  eflectually 
prevent  ib  ptLiKing  in  any  other.  It  was,  indeed,  from  reflecting 
on  tile  stracliKO  and  necessary  office  of  these  valves,  tliat  led  the

immortal  Harvey  to  discover  the  circulation  of  the  blood. 
Another  circumstance  peculiar  to  the  veins  is  their  situation, 
being  mostly  near  the  surface  of  the  body,  whilst  the  arteries 
are  generally  deep  seated.  The  wisdom  of  this  provision  ia 
evident:  it  is  well  known  ihat  in  wounds  it  is  readily  ascer- 
tained if  an  artery  be  wounded  by  the  jet  of  blood  that  ensues, 
and  which,  even  from  an  artery  of  small  size,  is  very  consider- 
able, and  the  danger  of  death  from  bleeding  is  often  great  in 
consequence  of  the  force  wirh  which  the  biood  is  thrown  into 
these  vessels.  Now  such  being  the  danger  attending  the  divi- 
sion of  arteries,  it  was  necessary  to  remove  them  as  much  as 
possible  from  the  risk  of  injuir,  and  accordingly  they  are  almost 
invariably  deep  seated,  and  when  they  do  approach  the  surface 
it  is  in  parts  least  likely  to  be  injured.  Thus  round  these 
important  vessels  nature  throws  a  thick  muscular  covering,  and 
protects  the  whole  by  a  mantle  so  sensitive  as  to  give  warning  to 
the  least  attack.  The  veins,  however,  do  not  cequire  this  care; 
in  them  tlie  circulation  is  languid,  and  their  wounds  are  com- 
paratively unimportant  and  unattended  with  danger,  for  the 
blood  generally  stops,  without  assistance,  from  its  coagulating 
quali^.  It  is  also  of  importance  that  the  greater  portion  of  the 
veins  should  be  situated  near  the  surface,  in  order  to  receive  the 
influence  of  the  atmospheric  pressure,  which  greatly  assists  the 
motion  of  the  blood;  and  it  has  also  been  found  that  veins 
possess  a  power  of  absorption  in  common  with  a  particular  order 
of  vessels  called  the  absorbents ;  thus  these  various  purposes  are 
effected  by  the  relative  position  of  the  veins  and  arteries. 

The  structure  of  the  veins  is  very  dif&rent  from  that  of  the 
arteries ;  for  whilst  the  latter  are  thick,  elastic,  and  composed 
of  three  coats,  the  former  are  thin,  inelastic,  and  composed  only 
of  two  coverings.  But  although  thin,  they  are  yet  capable  of 
a£Fbrding  great  resistance  to  pressure;  for  Dr.  Hales  found  that 
the  jugular  vein  of  a  mare  required  a  force  equal  to  a  column  of 
water  144  feet  high  to  burst  it. 

We  have  seen  that  the  blood  is  sent  to  all  parts  of  the  body 
by  the  action  of  the  heart  and  arteries,  but  what  is  the  cause  of 
its  return?  First  in  importance  is  the  \av/ of  Itt/drostatics,  "  that 
kll  fluids  support  their  level."  Thus  the  same  law  by  which 
springs  arise,  and  streams  are  produced,  and  rivers  (low  towards 
the  sea,  is  brought  to  bear  in  the  living  system,  and  enables  the 
blood  in  the  arteries  to  support  that  in  the  veins.  This  effect 
ia  ^freatly  assisted  by  the  action  of  the  valves  in  supporting  the 
column  of  blood.  The  blood,  thus  supported  and  propelled  by 
thearteries,  assisted  by  atmospheric  pressure,  must  go  somewhere, 
as  the  valves  prevent  return  :  it  goes,  therefore,  where  a  vacancy 
is  afibrded,  and  that  is  in  the  right  auricle  of  the  heart,  which 
has  just  propelled  its  contents  into  the  ventricle.     To  these

^itE  Jiliiod  is  by  far  the  most  important  fluid  in  the  animsl 
machine;  it  stimulates  the  heart  to  contract;  secretes  and  nou-

and  altliuugh  it  i»  the  *ouree  whence  other  lluida  are  obtained, 
it  is  yet  a  fluid  »ui  ymrrif,  differing  from  all  others.  Soot)  after 
it  is  drawn  from  tlic  body  it  coagtdates,  and  then  separates  into 
two  parts,— tlie  Sffttm,  a  watery  colourless  fluid  which  floats  on 
tlu'  top,  and  tlte  CVojuviini^mm,  which  appears  of  a  Arm  consist- 
ency and  a  rc<l  colour.  The  serum  is  a  peculiar  fluid,  and  may 
be  s«-parated  into  its  contlitueul  principles.     If  subjected  to  a

temperature  of  150"  a  portion  is  converted  into  a  substance 
resembling  albumen,  or  the  white  of  an  egg ;  the  other  portion 
remains  fluid,  and  is  termed  the  serosity  of  the  blood,  and  is  that 
which  constitutes  the  gravy  in  meat.  The  serum  contains  seve- 
ral salts  in  solution,  the  most  abundant  of  which  is  soda. 

The  Crauameatum  is  likewise  divisible  into  two  portions,  the 
Cruor,  which  gives  to  the  blood  its  purple  hue ;  and  the  Lymph, 
which  is  more  solid  in  its  nature,  and  is  considered  the  basis  of 
the  coagulum.  The  latter  can  be  separated  from  the  former  by 
washing,  and  likewise  separates  when  the  blood  is  a  long  time 
coagulating,  in  which  case  the  red  portion  of  the  blood,  being 
the  heaviest,  falls  to  the  bottom  of  the  vessel,  leaving  the  lympn 
on  the  top.  The  cruor,  or  red  portion  of  the  blood,  has  been 
fouDd,  on  submitting  it  to  a  microscope,  to  be  composed  of 
globules,  which  are  supposed  to  be  each  about  the  three  or  four 
thousandth  part  of  an  inch  in  diameter.  It  is  therefore  to  these 
globules  that  the  blood  owes  its  redness ;  but  the  intensity  of  the 
colour  is  subject  to  great  variation,  being  darker  in  animals  that 
are  poorly  fed ;  or  when  exposed  to  carbonic  acid ;  and  becom- 
ing more  florid  in  others  that  are  well  fed ;  and  also  when 
exposed  to  oxygen,  or  to  atmospheric  air. 

The  other  part  of  the  crcutamentum,  the  lymph,  which,  from 
its  nature,  is  also  called  the  Fibrin,  is,  in  fact,  the  most  important 
of  all ;  for  it  is  that  which  mainly  supplies  the  different  parts  of 
the  body,  particularly  the  muscles,  with  nutriment,  and  repairs 
wounds  and  fractures  in  an  extraordinary  manner.  Unlike  the 
cntor,  it  exists  in  the  blood  of  all  animals,  and  in  every  part  of 
the  system.  Some  animals  have  entirely  white  blood,  tne  cruor 
being  absent;  and  in  red-blooded  animals  there  are  some  por- 
tions of  the  body,  such  as  the  white  of  the  eye,  where  the  vessels 
are  so  small  that  they  do  not  admit  the  red  globules. 

The  specific  gravity  of  the  blood  rather  exceeds  that  of  water ; 
but  venous  blood  is  somewhat  heavier  than  arterial. 

The  temperature  of  the  blood  varies  in  different  animals;  in 
man  it  is  90°,  but  in  the  horse  upwards  of  100°.  It  is  rather 
warmer  tn  the  arteries  than  in  the  veins,  and  is  liable  to  variation 
from  disease,  it  having  been  found  in  severe  inflammations  to  be 
raised  7°  in  man,  and  in  the  cold  fit  of  agues  4°  lower  than  in  a 
state  of  health:  it  is,  however,  but  slighdy  raised  or  depressed 
by  external  temperature.  It  was  not  till  comparatively  a  recent 
date,  that  the  blood  has  been  considered  to  possess  vitality,  which, 
however,  is  now  generally  acknowledged.  The  vitality  and 
fluidity  of  the  blood  is  intimately  associated ;  in  fact,  its  co- 
agulation, when  removed  from  the  body,  constitutes  its  death, 
Tiie  time  in  which  this  is  taking  place  is  different  in  different 
animals,  and  is  influenced  by  various  circumstances.  In  strong 
animals^  such  as  the  horse,  it  is  longer  than  in  sucli  weak  animals

ON    RESPIRATION,    ANO    ITS    EFFECTS. 

^The  phenomenon  of  respiration,  which  is  carried  on  from  the 
first  minute  afler  birth  to  the  last  of  existence,  consists  of  two 
acts,  expiration  and  inspiration.  The  former,  that  of  inhaling 
the  atmosphere,  is  accomplished  mostly  by  the  diaphragm,  which, 
in  its  relaxed  state,  is  convex  towards  the  chesL  As  its  fibres 
contract,  the  muscle  flattens,  and  thus  enlarges  in  a  considerable 
degree  the  cavity  of  the  thorax.  A  vacuum  is  thus  produced, 
or  rather  a  tendency  towards  it ;  for  the  air  rushes  into  the  lungs, 
and  the  blood  into  the  heart ;  and,  as  the  lungs  are  elastic  and 
spongy  in  their  nature,  they  become  closely  adapted  to  the 
enlargement  of  the  chest,  and  prevent  any  vacuum  from  taking 
place  between  them  and  the  sides  of  the  thorax. 

The  diaphragm  is  thus  the  chief  agent  in  the  act  of  inspiration, 
although  in  some  degree  assisted  by  the  intercostal  muscles,  which 
raise  the  chest ;  and,  also,  when  the  breathing  is  violently  excited 
by  those  muscles  that  in  quadrupeds  attacn  the  fore  extremi- 
ties to  the  body.  This  may  be  witnessed  in  horses  after  severe 
galloping,  and  also  when  labouring  under  infiammalion  of  the 
lungs,  in  which  disease  the  animal  seldom-  or  never  lies  down, 
but  makes  use  of  the  fore  legs  as  fixed  points  to  assist  in  enlarg- 
ing the  chest.  The  air  thus  drawn  into  the  lungs  traverses 
throughout  its  internal  surface,  and,  having  fulfilled  its  office,  is 
forced  out  by  the  act  of  expiration.  This  part  of  the  process  is 
effected  chiefly  by  means  of  the  elasticity  of  the  lungs,  which  acts 
as  soon  as  the  diaphragm  becomes  passive,  assisted,  however,  in 
some  degree,  by  the  elastic  cartilages  of  the  chest,  and  occasion- 
ally by  the  abdominal  muscles.  In  a  healthy  horse,  in  a.  state  of 
rest,  there  are  from  four  to  eight  respirations  in  a  minute, 
jvhich,  however,  is  increased  by  the  slightest  exercise.

placed  in  (his  gas  is  immediately  exiiiigtiished ;  so  iJiat  it  is  tiwd 
as  a  safeguard  in  descending  into  these  low  and  fotd  places,  for 
whatever  will  not  support  combustion  will  not  support  life.  It 
is  not  a  simple  gas  like  oxygen,  but  is  formed  by  the  union  of 
caHton  and  oxygen. 

iViVroi/m  or  mnte  ia  ti  simple  gas.  but  its  use  in  ibe  atmosphere 
Beems  to  be  of  a  passive  nature,  being  for  the  puqmse  of  diluting 
tlie  oxygen,  and  rendering  it  less  slimuhiting.  It  will  not 
alone  support  life  or  combustion,  but  is  chemically  mixed  wttli 
the  oxygen. 

Oxygen  is  essential  for  tlie  support  of  hfe  and  combitslion ;  for 
if  air  be  deprived  of  it  no  animal  can  live,  nor  will  a  candle 
remain  lighted.  It  is  abundantly  furnished  by  plants  ai>d  shrubs, 
which  thus  supply  the  diminution  of  it  created  by  animals. 
When  a  Hame  is  exposed  to  this  ga.t  it  greatly  increasr«  in  bril- 
liancy; and  when  venous  blood  is  submitted  (o  it,  it  quickly 
becomes  florid.

not  by  actual  couluct,  but  ihniugh  the  membrane  which  forma 
tlie«e  cells;  and  by  (his  means  the  important  change  is  elTecled. 

There  is,  we  well  know,  a  conxidcrubU^  difii?rencc  between  (lie 
expired  and  the  in^^pired  air ;  the  former  is  hot,  the  latter  cohl ;

1*beiv  is  but  little  difTcrence  in  quantity  between  the  air  in  its 
diUcrent  states;  but  the  oxygen  in  expired  air  has  nearly  d it- 
appeared,  and  carbonic  acid  gas  is  found  in  its  stead;  it  also 
oonlaiiis  much  aqueous  vapour,  which  is  condensed  in  a  visible 


KEBPIRATIOK,   AND   ITS   EFFECTS.  50 

form,  at  a  temperature  of  60°.  Thus,  although  the  carbonic  acid 
gas  is  much  heavier  than  common  air,  yet,  partly  from  the 
aqueous  vapour  which  the  expired  air  contains  being  much 
lighter,  but  principally  from  its  increased  temperature,  the  ex- 

fiired  air,  notwithstanding  its  carbonic  acid,  is  yet  specifically 
ighter  than  the  atmosphere,  and  consequently  rises  upwards,  and 
thus,  in  great  measure,  is  prevented  from  being  respired  a  second 
time. 

It  has  been  found  by  experiment,  with  a  portion  of  atmospheric 
air,  containing  80  parts  of  nitrogen,  18  of  oxygen,  and  2  of  car- 
bonicacid,  thaton  being  respired,tlie  nitrogen  continued  the  same, 
but  the  carbonic  acid  was  increased  to  13  parts,  and  the  oxygen 
reduced  to  5;  whence  it  appeared,  that  11  parts  of  carbonic  acid 
were  substituted  for  13  of  oxygen,  2  parts  having  entirely  disap- 
peared. Thus,  the  disappearance  of  the  greater  portion  of  the 
oxygen,  was  accounted  for  by  its  being  converted  into  carbonic 
acid;  but  there  remained  a  small  portion,  whose  absence  could 
not  be  thus  explained,  more  particularly  as  Sir  H.  Davy  caI- 
culated,  that  about  32  ounces  of  oxygen  were  necessary  for  24 
hours'  expenditure  in  a  man ;  but  only  26(  ounces  are  requisite 
for  the  formation  of  even  37  ounces  of  carbonic  acid  gas,  giving 
us  an  unexplained  surplus  of  5J  ounces  of  oxygen  during  the 
above  period.  By  some  it  was  supposed,  that  this  surplus  oxy- 
een  unites  with  the  hydrogen  thrown  off  by  the  blood,  and  is 
uiUB  converted  into  watery  vapour :  by  others  it  is  held,  that  this 
oxygen  b  absorbed  by  the  blood,  and  enters  the  circulation. 

Oirbonic  acid  gas  is  exhaled  from  the  lungs  in  different  quan- 
tities during  different  periods  of  the  day,  being  generated  in  the 
greatest  quantity  about  noon,  decreasing  in  the  afternoon  and 
night,  and  again  increasing  in  the  morning.  It  also  increases  in 
man  by  taking  animal  food- 
Sir  H.  Davy  contended,  that  a  small  portion  of  nitrogen  is 
absorbed  by  uie  blood;  but  this  has  b^n  denied  by  others. 
The  chief  use  of  nitrogen,  however,  is  to  dilute  the  oxygen;  for 
if  the  latter  is  inspired  pare,  a  sense  of  warmth  is  felt  in  the 
chest,  the  heat  of  the  skin  is  raised,  the  pulse  quickened,  and 
other  symptoms  of  excitement  are  produced;  but  if  the  oxygen 
is  diminished,  a  sense  of  languor,  and  disposition  to  sleep,  is  pro- 
duced. A  given  quantity  of  oxygen  will,  however,  support  life 
longer  than  the  same  quantity  of  atmospheric  air.  It  has  been 
computed  that,  in  the  course  of  twenty-four  hours,about  2  lb.  8oz. 
of  oxygen  is  consumed  by  a  man. 

Aner  an  ordinary  respiration,  a  considerable  quantity  of  air 
•tUI  remains,  perhaps  live-fourths  more  than  has  been  expired. 

Having  mentioned  the  changes  that  take  place  in  the  atmo- 
•phere,  we  must  next  consider  in  wliat  manner  the  blood  becomes 
•o  altered  by  its  passage  through  the  lungs.

Tlie blood,  as  it  travonmhroiigli  the  body,  grtultinlly  Wconm 
darker ;  ic  U  loaded  with  carbon,  and  is  rcnd<>rwl  utiht  for  the 
circulalion,  and  in  this  state  it  is  t-alU-d  venous  blood  :  if  venous 
blood  taken  out  of  ilic  body  bi-  exposed  to  uxygpn.  it  quickly 
iK-coniea  red ;  and  so  il  does  it  vxp09«]  to  tlic  atmosphere,  but  not 
so  rapidly.  So,  likewise,  ifarterml  blood  be  exposi?d  to  carbonic 
acid,  it  quickly  acquires  the  colour  and  clisivcter  of  venoui 
blood.  ID  the  same  manner  is  ttw  colour  of  the  bluod  changed 
in  tlie  lungs:  thus  the  principal  use  of  n-spiration  appears  to 
be,  to  free  the  blood  from  its  impurities ;  and  this  is  eSected. 
although  the  air  and  the  blood  do  not  actually  come  in  coniacc. 
It  was  found,  that  if  blood  in  a  common  bliidder  were  exposed 
to  tlie  atmosphere  for  some  time,  it  acquired  a  coaling  of  florid 
r  blood ;  and  tliuH  as  the  membrane  lining  tlie  air  cells  is  by  no 
I  means  so  thick  as  that  of  the  bladder,  tliere  is  no  longer  any  dif- 
ficultv  in  accounting  for  the  ch<inge  taking  place. 

It  lias  been  tliv  subject  of  some  dispute,  as  to  nlu-re  the  change, 
or  rather  exchange,  takes  place,  some  contending  iliat  the  carbon 
unites  with  the  oxygen  in  the  air  cells,  whilst  olliers  maintain 
that  the  oxygen  enters  (he  bloorl,  and  there  unites  with  the 
carbon,  forming  carbonic  acid  gas,  which  is  then  exhaled  into 
the  air  cells.  It  van  found,  however,  that  if  venous  blood  was 
put  within  ilie  exhaui!te<i  receiver  of  an  air  pump,  a  quantity  of 
curbonic  acid  escaped,  llins  proving  the  presence  of  thia  gas  in 
Ltlie  blood,  and  supporting  the  second  theory.  And  as  there 
'appours  to  be  a  greater  quantity  of  oxygen  abstracted  from  the 
atmosphere  than  can  be  accounted  for  by  the  formation  of  car- 
bouic  acid,  we  must  conclude  that  a  portion  mingles  with  the 
blood  and  enten  the  circulation  ;  which  theory  agrees  with  tlie 
fact,  that  it  has  retenlly  l>eeu  discovered  bycorivct  analysis,  that 
both  venous  and  arterial  blood  contains  carbonic  acid,  nitrogen, 
and  oxy)n.-n,  but  that  the  latter  gas  is  most  abtuidant  in  arterial, 
and  the  lormer  in  venous  blood. 

Although  the  action  of  the  heart  is  much  more  frequent  than 
that  of  the  chest  in  respiration,  yet  there  is  a  most  intimate  c<«i- 
ncction  between  the  one  and  the  other;  for  besides  llie  changes 
which  we  have  spoken  of  in  the  blood,  it  rushes  into  me 
heart  when  the  chest  is  expanded,  and  when  from  any  cauw  re- 
upiratioii  is  delayed,  the  pulse  becomes  lets  frequent  and  more 
Hanguid,  in  consequence  of  the  obstruction  in  the  current  of  lite 
blood.  Thus  in  violent  fits  of  coughing,  the  chest  colla[ii<-ji,  the 
air  is  expelled,  and  ilic  blood  not  being  purified,  i*  unfit  fur  cir> 
cuktion,  and  the  consetguence  is,  the  veins  of  the  head  U'rome 
distended,  and  in  man  the  person  becomes  red  or  black  in  the 
face,  and  sometimes  a  bhiod  vessel  has  ruptured,  and  death

effected  by  means  of  respiration,  —  the  chemical  process  carried 
on  in  the  luncs. 

The  sensation  of  heat  is  derived  from  the  presence  of  an  ex- 
tremely subtle  fluid,  called  caloric,  the  particles  of  which  have  a 
tendency  to  repel  each  other,  and  unite  with  other  substances. 
Thus  if  we  touch  a  body  whose  temperature  is  lower  than  that 
of  our  band,  caloric  passes  from  the  hand  to  this  substance,  and 
the  sensation  of  cold  is  experienced ;  and  if,  on  the  other  hand,  the 
temperature  of  the  substance  is  higher,  we  feel  a  degree  of  heat 
from  the  passofje  of  caloric  into  the  hand.  It  is  a  singular  fact, 
that  this  caloric  may  exist  in  two  different  states,  the  one  in  a 
free  or  sensible  form,  the  other  in  a  latent  or  combined  form. 
Thus  two  substances  may  appear  to  be  of  the  same  temperature, 
and  yet  one  may  contain  a  much  greater  degree  of  caloric  than 
the  other,  but  so  combined  with  the  substance,  that  it  is  not 
sensible  to  the  touch.  If,  however,  the  object  be  exposed  to 
the  influence  of  some  chemical  agent,  its  latent  caloric  may  be 
set  free  or  rendered  sensible.  For  instance,  if  sulphuric  acid 
and  water  be  mixed  together,  although  each  fluid  were  before 
cold,  the  mixture  is  raised  to  a  high  temperature,  and  caloric  is 
evolved.  In  the  fermentation  of  malt  liquors  the  temperature  of 
the  liquid  is  raised  with  the  process,  and  carbonic  acid  is  pro- 
duced. And  it  is  found  that  whenever  this  gas  is  evolved,  that 
caloric  is  produced  and  rendered  sensible:  thus  in  the  lungs, 
the  oxygen  of  the  atmosphere  combines  with  the  carbon  of  the 
blood,  and  carbonic  acid  is  produced  as  in  fermentation.  What 
becomes  then  of  this  caloric?  One  portion  is  expired  in  a  sensible 
form  with  the  breath,  which  is  thus  rendered  hotter  and  conse- 
quently lighter,  and  thereby  ascends  :  another  portion  becomes 
sensible  in  the  blood,  and  raises  its  temperature  two  degrees,  but 
by  far  the  greater  portion  of  caloric  is  acquired  by  the  arterial 
blood,  and  there  remains  in  a  latent  form.  Some  substances 
have  a  much  greater  capacity  for  caloric  than  others ;  thus  arterial 
blood  has  more  than  venous  blood  :  this  being  the  case,  as  the 
blood  loses  its  arterial  character  in  the  course  of  circulation, 
it  loses  also  its  capacity  for  retaining  caloric,  and  as  the  blood 
acquires  carbon,  it  gives  out  caloric  in  a  sensible  form,  and  thereby 
every  portion  of  the  body  is  supplied  with  heat,  with  the  regu- 
larity and  precision  of  the  most  beautiful  machinery.  And  thus 
every  animal  bears  about  with  him,  safely  packed  away  in  the 
cavity  of  the  chest,  a  chemical  apparatus,  superior  to  any  which 
the  laboratory  of  the  chemist  can  supply,  an  apparatus  adapted  to 
all  climates  and  all  temperatures,  which  in  one  moment  can 
convert  the  frozen  element  of  the  northern  pole  into  the  very 
material  of  physical  heat.  —  Ed.]

THK   MOUTH   AND  THROAT,   KTC. 

[The  moutli  of  the  horse  is  of  great  extent,  which  is  necessary  in 

order  to  contain  a  large  qu&niiiy  of  food,  and,  also,   to  afford 

AockeU  for  the  large  molar  teeth.     It  is  wider  aiid  dce{)er  at  tlie 

upper  part  towards  the  throat  than  U  the  lower.     It  is  bounded 

in  front  priiicii>ally  by  the  anteiior  maxillary  bone)  by  whicli  it 

jiB  separated  from  ihe  noBtrih,  and  posteriorly  by  ilie  numerous 

'  muscles  situated  between  tlic  brandies  of  the  posterior  jaw  bonb 

Jl  is  lined  at  every  part  by  a  mucous  membrane,  wliich,  however, 

lis  not  immediately  placed  on  the  bone,  there  being  a  tJiick  6m 

substance  interposed. 

These  membranes  are  corrugated  at  the  upper  jaw,  and  be- 
tween the  incisor  and  maxillary  tcelh,  forming  what  are  com- 
monly called  the  bars,  and  where  horses  are  sometimes  bled: 
these  bars  are  also  the  seat  of  lanipas.  The  gums  of  the  nMUtJi 
are  also  composed  of  these  membranes,  which  thus  alFord  security 
to  the  teeili, 

The  ai<Ies  of  the  mouth  ai-e  formed  by  the  cheeks,  which  arc 
composed  of  skin  and  membrane,  sufficiently  loose  to  admit  the 
limited  motion  of  the  jaws  ;  they  are  connected  with  tlic  powerful 
niasscter  muscles,  which  form  ihc  greater  part  of  tlic  bulk  of  ll>e 
face,  and  princiiially  axsiHi  in  the  grinding  motion  of  the  jaws. 
In  the  skull  we  find  the  lower  jaw  considerably  narrower  thao 
the  upper,  but  in  the  living  animal  this  docs  not  appear,  tlie 
.jvpnce  being  occupied  by  the  masseter  muscles. 

'Ilie  li|i-i  groiily  asuixi  in  gaiheriii]^  together  the  food,  and  are 
largely  fmnithed  with  ihe  nerve^t  of  feeling;  they  are  con)|xMed 
of  skin,  muscle,  and  inenibiane,  and  possess  the  powers  of  motion 
and  sensation  in  a  high  degree. 

The  mouth  is  abundantly  supplied  with  a  watery  fluid  called 
saliva,  pnrticnlarlv  during  mastication,  when  it  is  secreted  and 
poured  in  in  considerable  quantities.  This  thiid  is  secrcred  by 
lliree  pairs  of  glands,  the  largest  ofwliicli  an:  tlie  |))irotid,  »• 
tnnierl  at  ihe  rout  uf  the  ear,  and  rrotn  which  ducts  convey  the 
fluid  to  the  mouili,  Icnninnting  opposite  the  second  molar 
leetli.  The  sulimaxillarii- glands  are  )>iiuaied  under  ihvjaws,  aiid 
their  ducLH  termlnaiv  in  tubular  eminence  near  the  fni'tnim 
or  bridle  of  ilie  tongue.  The  other  siilivary  glundH  are  the  sub* 
lingual,  situaied  under  the  tongue,  and  its  ducts  terminate 
rather  higher  up  than  ihow  last  described. 

The  mouth  is  principally  filled  with  the  tongue,  which  u 
tnnsculnr  in  its  structure,  and  very  flexible,  being  iiidei-d  a  prin* 


THE   HOUTB    AND    THROAT,    £TC.  68 

cipal  agent  in  mastication  and  swallowing.  It  is  larger  at 
the  upper  part  tlian  towards  its  tip,  and  is  confined  poste- 
riorly to  the  muscles  between  the  branches  of  the  lower  jaw, 
by  a  sort  of  fleshy  bridle,  and  above  to  a  singularly  shaped 
bone,  called  the  os  hyoides.  It  possesses  both  the  power  of 
feeling  and  tasting,  and  for  this  purpose  is  well  supplied  with 
two  Ascriptions  of  nerves,  and  is  covered  by  both  cutis  and 
cuticle. 

The  cavity  of  the  mouth  is  separated  from  that  of  the  nostrils 
by  the  soft  palate,  a  muscular  membranous  substance  fastened 
to  the  semicircular  border  of  the  palate  bones,  and  hanging 
down  on  the  back  of  the  tongue,  so  that  in  the  ordinary  state 
there  is  no  open  communication  between  the  mouth  and  the 
throat,  and  thus  all  breathing  is  carried  on  by  the  nostrils,  and 
fluids  coming  either  from  the  lungs  or  the  stomach  pass  into 
the  nostrils.  When,  however,  food  is  passing  to  the  stomach,  it 
raises  this  membrane,  and  then  enters  the  pharynx,  the  mem- 
brane immediately  afterwards  falling  down  into  its  old  situation. 

The  Pharynx,  or  food  bag,  is  a  muscular  cavity,  situated  at  the 
root  of  the  tongue,  and  immediately  above  and  adjoining  the 
larynx.  It  receives  the  food  from  the  mouth,  and  by  its  mus- 
cumr  power  forces  it  into  the  oesophagus.  It  is  this  part  that  is 
afiected  in  catarrh  when  there  is  a  difficulty  in  swallowing. 

The  (Esophoffus  is  a  long  tube,  commencing  at  the  pharynx, 
and  ending  in  the  Btomach.  It  passes  down  the  neck  rather 
above  the  windpipe,  and  towards  the  left  side  enters  the  chest; 
it  traverses  ite  upper  part,  pierces  the  diaphragm,  and  ends  by 
a  sort  of  curvature  in  the  cardiac  orifice  of  the  stomach.  It  is 
lined  in  common  with  the  mouth  and  alimentary  canal  by  a 
mucous  membrane;  but  it  is  principally  composed  of  two  orders 
of  muscular  fibres,  one  circular,  the  other  longitudinal,  by  which 
it  is  enabled  to  propel  the  food  forward,  into  the  stomach.  In 
addition  to  this  there  is  a  white  cuticular  coat  between  the 
muscular  and  the  mucous,  and  which  also  lines  half  the  stomach. 

The  larynx,  the  pharynx,  and  tlie  tongue,  are  connected 
together,  and  to  the  upper  jaw  bone,  or  rather  lo  the  bones  of 
the  head,  by  means  of  the  os  hyoides,  so  called  from  its  resem- 
blance to  a  spur.  The  semicircular  part  of  the  spur  embraces 
ID  a  manner  the  larynx;  whilst  the  shaft  is  intimately  con- 
nected with  the  root  of  the  tongue:  this  part  in  the  horse  is 
much  longer  than  in  the  ox,  and  thus  confines  the  motion  of  the 
tongue  in  a  great  degree.  The  os  hyoides  has  two  long  appen- 
dages, which  articulate  with  the  temporal  bone.  Thus  situated 
cuid  constituted,  this  bone  gives  great  support  to  the  soft  parts 
connected  with  it,  whilst,  at  the  same  time,  it  freely  admits  their 
extensive  mobility.  In  the  act  of  swallowing,  therefore,  this 
bone  is  greatly  called  into  action.

from  iIm*  fourtli  coat  by  a  waving  line.  It  extends  over  the  left 
estremitv,  and  its  elasticity  enables  it  to  accommodate  itself  to 
the  varying  size  of  tbe  stomach.  Tlie  Tourth  coal,  called  tlie 
vtllouB  or  mucous,  lines  the  larger  Imlf  of  tttu  stomacb.  It  it 
8omcwl>at  red  or  yellow  in  iu  colour,  Is  very  rasctdar  and  sen- 
sible, and  exhitMls  numerous  processes,  having;  ihe  appearance 
of  velvet,  which  arc  indeeil  the  minute  raniiRcaltons  of  blood 
vctsels,  by  which  a  most  important  fluid  is  G«Tri-ti.il,  called  tlie 
gastric  juice. 

Hie  stomach  han  two  extrrmili***,  the  right  and  iIh>  left ;  tlie 
latter  of  which  is  the  larger,  and  terminates  in  a  wrt  of  pouch. 

It  ha^  also  two  curvnlui'e«,  n  larf^  and  a  small  one:  (o  the

the  Biiiall  intestines.  'I'ho  lormer  is  callra  Ine  canliac  orifice, 
and  is  situated  about  tlie  middie  of  the  snml)  curvature.  It  lias 
a  sort  of  valve  formed  by  the  duplication  of  its  membranes,  and 
is  kept  constantly  closed,  except  when  food  is  jiassing. 

The  other  orifice,  called  the  pyloric,  is  situated  at  the  riglit  or 
small  end  of  the  stomach,  and  Is  usually  open,  but  has  tlie  power 
of  closing.  Thus  situated,  these  openings  are  not  far  distant  from 
each  other,  and  in  tbe  usual  pDsition  of  the  animal  ibey  are 
situated  superiorly.  Thecc^oplmgus,  just  previous  to  its  entering 
llie  stomach,  makes  an  acute  angle,  by  which  means,  m  great 
measure,  vomiting  in  the  horse  isaVmost  entirely  forWddeii.  The 
stomach  is  kept  in  its  situation  princijuilly  by  the  te&ophagiis 
and  the  duodenum  :  but  it  is  also  attached  by  means  of  perito- 
neum to  the  spleen,  liver,  colon,  and  diaphragm. 

The  stomach  of  the  horse  will  usually  contain  about  three 
gallons. 

The  inti'Stincs  an^  usually  distinguished  into  tbe  small  and

and  the  itertam.  Tlie  small  inteitines  terminate  in  a  wculiar 
manner,  by  ]ircijectinff  at  right  angles  into  a  cavity,  called  tlic 
blind  head  of  tlic  colon,  at  which  place  there  is  a  valve  which 
prevents  the  food  reiurninff.  From  this  blind  head  the  cawum, 
wliich  will  contain  about  four  ^llons,  extends  don-nwards  and 
forvrnrda  into  a  blind  extremitv,  it  tiaving,  indeed,  but  one

for  fluids ;  Tor  it  hn>  been  Ibuud  that  shortlv  aftLT  a  lionte  haa  had

The  internal  surface  of  this  gut  is  formed  into  cells,  by-  which

in  iiddition  to  the  n-sistance  nmde  by  this  valvular  structure  to 
the  escape  of  the  air  which  is  geiterati.'d  iu  the  stomach  and

of  clysters,  winch,  W proptrlu  mhniHwtrrfit,  will  completely  empty 
itie  eiocuni  and  large  bowels  iu  general. 

The  Coffm  is  the  largest  gm,  containing  as  much  as  twelve 
gallons,  being  more  than  the  whole  of  the  small  intestine*.  This 
gill  commences  at  the  blind  head  in  which  ilie  ilewm  terminates ; 
it  quickly  assumes  a  ffTeat  siite,  l)eing  larger  than  the  stomach;

It  haa  no  evils,  and  is  only  partially  covered  by  pcritoneiimt 
but  ita  niuwular  coal  is  considerably  (Stronger  than  the  oihtra, 
and  enables  it,  with  the  assistance  of  ilie  aiidomiiial  muscles,  to 
expel  the  r^ceo.  This  gut  terminates  in  tl)e  anus,  which  is  kept 
closed  by  means  of  a  circular  muscle,  called  the  sphincter  ani, 
which  is  alwaj'B  in  action,  except  when  the  dung  is  being 
exptilled.  The  small  intestines  are  about  twenty-two  yards  in 
lengtli,  and  tlie  large  about  eight. 

The  LIVER,  whose  of&co  it  u  to  Bvcreto  the  btlc,  is  a  gland, 
and  the  largest  onv  m  the  body.  It  is  conHiiod  to  tlir  diaphragm, 
and  kept  in  its  situation  by  strong  portions  of  pM-itoneum,  culled 
its  ligaments.  It  is  divt<U-d  pnrlially  into  thrt«  lubei';  the  right,

the  lalier  the  smulli-st;  hi-sidw  iIkih?  there  are  two  tmiidl  lobes.

with  ilieir  com4{(otuhng  vein*,  lo^^eilMT  with  nervu  and  ab- 
sorbents; bfil,  in  addition  to  theM>,  there  are  tome  large  veins 
which  convey  to  the  liver  bliu^,  impure  blood,  from  which  it 
secrete*  or  M-parales  [i>e  bile.  The  biie  being  thus  secreted,  is 
conveyed  by  means  of  tlie  hrputic  <hict  to  the  iluodenum,  which 
it  enters  about  six  inches  from  the  stomach.  Man  and  most 
animals  possess  a  gall  bladder  lor  the  reception  of,  and  as  a 
reM*rToir  for,  the  bile ;  but  the  horse  due«  not  possess  any,  so  that 
the  bile  is  almovt  continually  being  poiire<l  into  the  bowels. 
Hie  reason  of  this  peculiarity  is,  iliat  the  hone  in  n  slate  of 
nature  »  continuiilly  tecding ;  having  a  small  xiomaelt,  it  recpiin-s 
frequent  rei)leni.ihiiig,  and,  con!te(|uenlly,  there  is  a  continiiHt

[Tmf.  horse  is  a  vegetable  feeder;  in  a  stale  of  nature  his  food  ii 
confined  to  the  gra<N«  of  the  lieid  ;  and  although  in  a  domesticated 
stale  lie  largely  subsiets  on  nouiishmenl  in  a  more  concentrated 
form,  such  as  grain,  yet  it  is  impossible  to  make  him  lite  on 
animal  food ;  his  teeth,  bis  stomach  and  inu-etincs,  arc  all  adapted 
for  the  comminution  and  digestion  of  vo;;elablcs:  the  former 
are  broad,  tor  the  purpose  of  grinding  the  food  as  in  a  mill;  and 
the  interlines  are  bulky,  so  Wi  to  contain  a  large  quantity  of 
food. 

Till*  horse  at  grass  is  almost  constantly  feeding;  be  doos  not, 
like  the  ox,  gather  toffeiher  large  tufu  of  grass,  but  he  takes  a 
short  bite,  and  delignu  in  a  sweet  herbage.  The  manner  in 
which  he  gathers  bis  fuod  is  worthy  of  notice:  be  does  not  biu 
it  olf  witli  hiii  loelb,  but  having  closely  embraced  a  short  bile 
between  the  incisor  teeth  or  nippers,  he  pulls  it  oif  by  making  a 
alight  motion  of  the  hciid ;  this  is  the  only  duly  of  these  teeth, 
for  tlie  Longuv  ininicdialcly  passes  on  the  food  to  the  molar  leetll, 
between  which  it  is  (ground  a«  in  a  mill.  Tlie  under  molar  teeth  do

process,  that  of  rumination. 

Carnivorous  animals  have  a  capacious  stomach,  which  ihev 
nvenons)y  fill  with  a  large  quantity  of  animal  food,  after  which 

ley  become  sluggish  and  lie  down  and  sleep. 

lite  horse,  however,  in  a  natural  state,  is  almost  constantly  in 
loliun.  He  eats  when  he  can,  and  as  often  as  he  can,  and  is 
almost  immediately  afterwards  prepared  for  flight.  Having  a  stnall 
stomach,  it  does  not,  even  when  filled,  press  so  heavily  against  the 
diaphragm  as  to  impede  respiration,  as  with  other  aiiinials  we 
Iwve  mentioned  ;  and  although  the  practice  of  working  him  on 
a  full  stomach  is  by  no  mc^ns  to  be  recommended,  yet  it  is  eur- 
prising  what  exertions  he  is  capable  of  even  in  this  state. 

^litts  B  horse,  from  being  liirnished  with  a  small  stomach,  is 
rendered  n)ore  useful  for  purposes  of  speed,  or  draught,  and 
con»e<jiienily  more  Bcrviceable  to  man. 

'Ilw  food  having  entered  the  stomach,  is  there  su)>miitc<l  to 
ihc  action  of  a  fluid  secreted  by  the  villons  coat  of  the  stomach, 
and  tcrmetl  the  gattrir  juiet.  This  fluid  i.*  very  [leculiar  in  its 
nature,  and  lia«  the  power  of  separating  the  whey  from  milk.  It 
operated  chemically  on  thi?  food,  and  converts  it  into  a  noft  pulpy 
mus,  called  eliynie,  in  which  slate  it  is  piisMtl  into  the  small 
inteMines.  To  i-flV-ct  this  purp«is<-,  the  food  is  detained  in  ihe 
stomach  a  eonxidcnihle  lime,  during  which  time  it  i^  pressed 
upon  by  tlie  mnieitliir  coat  of  the  stomach,  and  moved  iitmut  so 
as  to  submit  every  [tortion  of  it  to  the  action  of  the  gastric  juice, 
l^iesioraach  of  tlie  horse difreri>  from  tliut  of  earnivorous  animals, 
not  only  in  the  poise&sian  of  its  cntieiilar  coat,  but  likewise 
in  the  fact  of  having  a  fundus  or  blind  end,  which  serves  the 
purpose  of  detaining  the  tinod,  making  it  necessary  for  it  to 
return  almost  to  the  same  place  where  it  entered  the  stomach 
before  it  can  pass  into  the  duodenum. 

Food  is  detained  in  the  stomach  different  periods,  according 
to  the  lime  required  for  its  conversion;  and  it  is  found  that  if 
both  corn  and  grass  be  given  a  iiorse,  that  tlie  latter  will  i)asa

The  pecuhar  properties  of  the  gastric  juice  are  that  of  being 
a  powcrftd  Bolvcnt,  and  an  aniitcptic,  and  liaving  a  pon-er  of 
cooi;idalion.  It  is  cauable  of  (bssolving  the  har(li>st  malerialt,

priipcrty  of  cmtgulntin;;  milk  and  albuminous  lliiids  is  useful  in 
converting  a  fluid  into  a  colid  Btiile,  imd  thus  detaining  it  in  Uic 
Dtoniiich  iinieli  longer  ttuut  would  otherwise  be  the  case. 

It  is  found,  in  ihi;  hoDte,  tiiat  if  a  ([uantily  of  water  be  given 
even  just  after  lliv  fund,  it  qui<:kly  paii»e«  through  the  stomacht

animal  food. 

In  the  human  suhject,  it  has  appeared  that  tlie  too  great  use 
of  soups,  abhoiigh  containing  a  very  large  proportion  of  nutri- 
ment, was  yet  productive  of  injury,  from  being  passed  too  quickly 
through  the  stomach. 

I  have  found  likewise,  that  when  bniised  oats  have  been  girto 
to  liorM-N  without  luiy  counteractive  agent,  it  has  l>een  productive 
of  diarrlicL-ii,  in  all  probability  from  the  circumstance  of  being 
^Kissed  loo  quickly  through  the  stomach.  And  ihe  vulgar  vrny 
of  explaining  the  looseness  in  waslty  horses  is  not  altC^ethcT 
destitute  of  foundation,  "  tlut  the  food  does  not  remain  long 
enough  in  tht-m  to  do  them  good."  During  the  active  proem

called  ehylificatioi).  The  pyloric  orifice  is  furnii^hud  with  a 
circular  band  of  fibres,  covered  by  a  fold  of  ihc  villoitv  or  iicrvou* 
coat,  which  appears  to  have,  by  its  extreme  sensibility,  a  power 
of  selecting  tiial  portion  of  the  food  which  bns  In-cn  stifficiently

[Shortly  after  the  food  enierj  the  duodenum  it  ia  submitted  to 
the  action  of  two  fluids ;  one  furnished  by  the  pancreas,  and  the 
otlier  by  the  liver.  The  pancreatic  juice  is  ven,'  aimilar  to  that 
of  saliva :  its  principal  use,  therefore,  api)ear3  to  be  to  dilute  ihe 
food  ;  hut  it  also  contains  much  albumen,  vrhich  forms  an  import- 
ant constituent  in  chyle.  VVe  can  readily  understand  how  csscn- 
tial  it  is  that  a  watery  fluid  should  liere  be  supplied.  In  the 
Uomach  it  would  be  unnecessary,  indeed  hurtful,  as  it  would 
liasten  the  expulsion  of  Its  contents  too  rapidly ;  but  in  the 
intestines,  in  order  that  the  chyle  should  be  extracted,  it  is  essen- 
tial that  the  foo<l  should  be  liquelied. 

Tlie  formation  of  chyle  is  the  immediate  result  of  the  admix- 
ture of  ttte  bile,  which  thus  has  a  chemical  action  on  it.

expelled ;  with  the  assistance,  however,  of  the  diaphragm  and  the 
abdominal  muscles. 

The  intestines,  both  large  and  small,  are  fastened  to  the  spine 
by  means  of  a  strong  membrane,  which  is  spread  out  in  a  radiated 
direction,  like  a  fan,  the  foci  of  which  are  of  course  towards  the 
spine.  That  part  of  the  membrane  which  is  attached  to  the 
small  intestines  is  termed  the  mesentery ;  and  the  other  portions 
are  termed  the  mesocolon  and  the  mesorectum,  according  to  the 
gut  to  which  it  is  connected.  This  membrane,  which  we  may  as  well 
designate  as  the  mesentery  throughout,  not  only  serves  to  sustain 
the  bowels,  but  also  to  afford  a  vehicle  for  their  important  vessels. 
TTius  we  have  numerous  arteries  for  the  nourishment  of  the  coats 
of  the  bowels,  and  to  furnish  their  internal  secretions.  We  have 
likewise  the  mesenteric  veins,  which  have  been  found  not  only 
to  return  the  venous  blood,  but  also  to  have  a  power  of  absorbing 
the  more  fluid  contents  of  the  bowels,  as  well  as  some  chemical 
agents  which  have  been  administered  for  experiment,  and  which 
the  lacteals  have  refused.  There  are  also  a  numerous  supply  of 
nerves  passing  to  the  bowels,  supplyinp^  them  with  nervous 
energy,  and  keeping  up  their  connection  with  the  sensorium. 
These  are  not  only  nerves  of  sensation,  but  also  of  involun- 
tary motion:  the  former  are  at  all  times  the  medium  of  com- 
mon feeling,  and  sometimes,  as  in  spasms  or  inflammation,  the 
source  of  ^e  most  intense  pain  ;  the  latter  endow  the  muscular 
coat  of  the  bowels  with  the  peculiar  peristaltic  or  vermicular 
action  it  possesses,  and  by  which  the  contents  are  passed  onwards. 
Lastly,  the  mesentery  abounds  with  minute  vessels,  called  the 
lacteals,  which  open  into  the  intestines,  and  absorb  the  chyle, 
and  convey  it  through  a  number  of  glands,  called  mesenteric 
glands*,  to  a  canal  denominated  the  receptaculum  chyli,  which 
takes  its  course  along  the  spine,  and  terminates  in  a  large  vein, 
just  before  it  reaches  the  heart.  The  lacteals  are  so  small  as  to 
be  ordinarily  imperceptible  to  the  naked  eye ;  and  they  seem  to 
possess  a  peculiar  sensibility  for  the  absorption  of  chyle,  which, 
however,  is  urged  onwards  by  means  of  capillary  attraction. 

Thus  the  beautiful  process  of  digestion  is  carried  on,  whereby 
the  grass  of  the  field  is  gradually  converted  into  the  various  and 
complicated  structure  of  animal  frames.  In  this  process  it  is 
easy  to  believe  how  the  imperfection  of  one  part  may  neutralise 
the  operation  of  another,  and  thereby  materially  impair  the  eifect 
of  the  whole.  Thus,  loss  of  condition,  so  often  met  with  in  the 
horse,  may  arise  either  from  deranged  stomach  or  intestines, 
from  dise^ed  secretions  of  the  glands,  or  from  obstruction  or 
disease  of  the  absorbent  vessels. —  Ed.]

OK   THE   L'RINARY   OIIOAMS. 

QTiie  urine  is  separated  from  the  bl<x>d  by  means  of  (he  kidncyti 
two  glaiHls  of  well-known  ^lape,  lying  one  on  cacli  side  of  tJie 
n>ine,  imniediately  under  the  Uimliar  rericbrw.  Unlike  tbe 
liver,  their  ]ower  eur&cea  only  are  covered  by  peritoneum;  aixl 
ihvy  arc  kept  in  their  siitmiion  partly  by  cellular  n>cinbra>ie

part,  where  they  end  in  minute  vessels  'Hieite  vesselk,  wlticb  are 
exceedingly  numerous,  terminate  in  little  globular  bodies,  by 
which  the  urine  is  separated.  TiiesuiK-rnuous  blood  is  retunied 
by  the  veins;  but  the  urine  is  conveyed  by  a  particular  act  ot 
vessels  into  a  reservoir,  called  the  pelviK,  sitiiaii-d  in  the  mo- 
duUary  pari  of  the  kidney.  l''r»m  tbo  |>elvi»  of  tbe  kidney  arise* 
a  long  wliite  tulxr,  called  the  ureter,  whidi  leaves  the  kidney  at 
its  notch,  and  runs  along  the  lumbar  vertebrte  to  the  pelvis  of  the 
body,  where  it  is  attached  to  the  upper  and  lateral  part  of  tlie 
bladder,  on  which  ii  continues  its  course  towards  the  neck  of  tbe 
bladder.  Before  it  reaches  tlic  neck  it  disappears,  by  penetrating 
the  external  coats  of  the  bladder,  passes  a  short  distance,  ana 
then  teriniiiulcs  by  piercing  the  inienial  coat  in  au  oblique 
direction. 

The  kidneys  are  well  supplied  with  nerves,  wblcli  enter  tbem 
with  the  blood  vessels. 

Near  the  kidneys  are  two  small  bodies,  called  the  capsula- 
renales,  whose  vsq  is  unknown. 

I1)c  BLADDEli  is  situated  entirely  within  the  cavity  of  llie 
pelvis,  when  in  an  undisiended  slate ;  but  when  full,  s  portion  of  it 
projects  into  the  abdomen.  It  is  attached  to  the  |>elvis  by  Cellular 
membrane,  but  is  chiefly  kept  in  it»  situation  by  means  of  peri- 
toneum, by  wbieli  it  i»  purlially  covered.  It  is  placed  at  the

usually  distinguished  into  three  {nrts :  the  Tundus,  the  body,  and 
die  cervix,  or  neck.  Tlie  fundus  is  the  round  extremity,  wliicb 
often  projecia  into  ibe  abdomen ;  the  body  forniB  ilie  principal 
bulk  of  tne  bladder;  and  the  cervix  is  the  posterior  narron-  part, 
which,  however,  a  thicker  than  the  rest,  and  is  united  to  tlie 
urethra. 

The  bladder  is  composed  of  three  coats:  the  external,  tlie 
internal,  and  the  muEcular.  Tho  former  is  formed  by  peritoneum^ 
and  covers  the  anterior  part  of  the  bladder  only.  The  internal, 
or  mucous  cost,  foriiu  the  principal  thickness  of  the  bladder,  and 
secretes  a  mucus  for  iu  interiml  lubrication,  and  to  prevent 
tl>c  irritating  vfTccI*  of  lltr  urine.  Tlii*  eoAt  pOMCssva  much  sen-

is  compoK-d  of  two  orders  of  fibres,  longitiidiiiiil  and  circular;

breadth,  and  lite  united  contriwiion  of  both  will  lessen  die  cavity 
M  M  to  ex|Mrl  the  conientK. 

The  m-ck  of  iht^  bladder  a  more  abundantly  furnislicd  with 
circular  fibres  iliati  tlie  other  jHirts,  and  their  omce  in  thta  sltiui- 
tion  is  to  prevent  the  urine  from  escaping  by  closing  the  cavity. 
Tlieae  fibres,  when  contracted  from  spasm,  occasion  a  retention 
of  tliM  uriiK>. 

The  urine  i>  discharged  from  the  body  through  a  membranous 
canni,  called  the  uretlmi,  which,  in  tlie  male,  is  of  coiuiderable 
length,  extending  from  iht-  bluddi-r  to  the  extremity  of  the  penis. 
It  first  lakes  a  course  from  tlie  neck  of  the  bladder  backwards, 
and  becomes  increased  in  size,  and  approaches  vcn'  near  the  skin, 
being,  indeed,  just  under  tlie  anus;  it  then  Kirms  an  acute 
angle,  tuniiug  downwards  and  forwards,  and  is  here  surrounded 
by  a  muscle,  called  the  accelerator  urinae,  and  continues  to  tlic 
extremity  of  the  penis. 

In  the  female  the  pa&^age  is  considerably  shorter,  being  about 
two  iiKhes  backward)  and  slightly  upward,  when  it  opens  into  the 
pudendum,  and  is  connected  with  tfie  organs  of  generation. 

The  UriHe  is  a  fluid  secreted  or  scjiarated  by  the  kidneys, 
and  poured  by  dicm  through  specific  cliannels,  the  nrefm,  into 
the  bladder.  Iu  a  state  of  licHlth  it  is  of  an  ninber  colour,  and 
its  peculiar  odour  is  well  known.  It  U  composed  chiefly  of 
water,  which  contains  some  salts,  and  a  p<-culiar  substance, 
called  nreo,  to  which  its  properties  arc  more  ]i»rticular1y  owing. 
The  colour  of  the  urine  is  much  lighter  after  a  large  quantity  of 
water  hn»  been  drunk;  ami  darker,  and  more  ncrid,  after  xolid 
fijod.  There  is  a  great  sym[M>lhy  between  the  kidneys  and  the

lomewhat  about  the  size  of  a  hen's  egg  when  full  grown.  To 
iie  upper  and  posterior  part  of  the  testicle  is  attached  the  vas 
iefi^rens;  and  to  the  upper  and  anterior  end  is  joined  the  sper- 
matic cord,  by  which  the  gland  is  suspended,  and  retained  in  its 
dtuation. 

The  substance  of  the  testicle  is  soft,  and  of  a  light  brown 
iolonr.  At  the  upper  part  of  the  testicle  is  found  what  is  called 
[be  Epididymis,  which  is  composed  principally  of  a  white  tube 
xmtaining  semen,  coiled  up  so  much  that  when  unwound  it 
Ims  been  found  several  yards  in  length.  The  epididymis  is 
laiger  at  each  extremity  than  in  the  middle.  These  extremities 
ire  called  the  globus  major  and  minor.  The  former,  and  larger, 
'm  situated  towards  the  front;  and  the  smaller  globe  is  found 
Eowards  the  back  part  of  the  testicle:  from  the  larger  globe, 
prhich  is  commonly  termed  the  nut,  and  is  indeed  about  the  size 
if  a  small  walnut,  the  vas  deferens  arises. 

The  Spermatic  Cord,  by  which  the  testicle  is  suspended,  is 
Minposed  of  numerous  parts,  although  not  by  any  means  bulky. 
in  their  structure.  There  are,  in  the  iirst  place,  no  less  than 
Four  distinct  coverings;  one  of  which,  called  the  cremaaler,  is 
muscular,  and  has  the  power  by  its  contraction  of  drawing  ilp 
ibe  testicle.  The  other  parts  of  the  cord  consist  of  arteries,  veins, 
ogives,  and  the  vas  deferens. 

The  arteries  are  two  in  number;  a  small  one,  belonging  to 
[he  cord;  and  a  larger  one,  the  spermatic,  supplying  the  testicle 
itself,  and  from  which  the  semen  is  secreted :  from  the  latter  the 
principal  bleeding  takes  place  in  the  operation  of  castration.  The 
reins  are  large  and  numerous,  and  accompany  the  arteries  in 
[heir  course,  together  with  the  nerves,  which  are  also  numerous, 
ilthough  small,  and  the  absorbent  vessels,  which  are  likewise 
lumerous. 

The  Vas  Deferens,  as  the  duct  which  conveys  the  seminal  fluid 
is  termed,  forms  a  part  of  the  cord,  which  can  readily  be  distin- 
niished  from  the  other  parts,  being  stout,  and  firm  to  the  touch. 
It  springs  from  the  small  end  of  the  epididymis,  at  the  anterior 
MTt  of  the  testicle,  and  consequently  does  not  at  first  join  the 
)ther  parts ;  it,  however,  gradually  approaches  them,  and  enters 
,he  abdomen  with  them,  when  it  ascends  to  the  pelvis,  and 
msaes  by  the  side  of  the  bladder,  about  an  inch  posterior  to 
vfaich  it  terminates  in  another  duct  not  yet  described. 

The  Scrotum,  or  bag  in  which  the  testes  are  found,  is  com- 
MMed  of  several  coverings.  We  have  externally  the  skin,  which 
■  soft  and  thin,  and  usually  dark.  It  is  equally  divided  by  a 
ongitudinal  crease,  called  the  raphe.  On  cutting  through  the 
kin,  we  find  a  layer  or  coat,  supposed  to  be  nmscular,  called  in 
luman  anatomy  the  dartos.  It  is  loosely  connected  by  mem- 
irane  with  the  skin  and  other  parts ;  and  a  portion  of  it  passing

Thua,  by  one  stroke  of  the  knifo,  we  sever  no  Icis  tluiii  three

ilirotigh  the  reflected  coat  or  tunica  albugineo,  as  tt>e  white  coat 
immediately  enveloping  the  testicle  is  termed. 

'I'he  testicles  at  birth  are,  like  those  of  man,  contained  within 
the  scrotum;  but,  after  five  or  six  months,  ihcy  arc  drawn  up 
between  tbc  externa)  and  internal  alKloniiiial  rings,  where  tiii'y 
remain  six  or  seven  months,  and  then  again  uesccnd  to  tbe 
scrotum. 

The  abdominal  rings  are  two  on  egwh  sidej  the  external  and 
the  iiitenial ;  the  former  is  the  opening  in  the  transrerw  muscin 
the  laller  in  the  fascia,  or  strong  monmrane,  which  irometlialcly 
contains  the  intc^tinos.  Tliey  are  not  placed  opposite  each  other, 
but  about  three  Inches  apart,  tlie  external  rin^  being  situated  at 
the  posterior  inferior  part  of  the  abdomen.  The  testicle  t 
loo,  hiis  n  coat  of  ]N-ritonvnm ;  and,  when  it  leaves  tlx.-  abdoi 
it  itirecM  that  portion  of  the  peritoneum  which  closes  iIh-  opci

Ktance  of  the  open  conuiinnlcAtion  existing  betwivn  the  ticrotillD

sage for  the  urine,  and  ejecting  the  lemcn,  is  «  long  flwhy  body, 
attached  to  the  pelvis  by  ligiuneiits  and  muscles.  It  Li  composed 
of  several  dislitici  jiarts,  besides  its  muscles,  which  are,  first,  a 
pair  called  iIk  ertdon,  situated  at  the  root  of  tlie  |>eiiis,  and  at*

the  OT^n,  by  promoting  the  influx  of  blood.  Then  we  have  a 
small  triangular  muscle,  situated  at  the  root  of  the  organ,  besides 
the  Accelerator,  which  envelopes  the  urethra,  and  ejects  with 
force  both  the  urine  and  the  semen. 

The  body  of  the  penis  is  formed  principally  of  two  tavemous 
bodies,  which,  by  the  power  they  possess  of  containing  a  large 
quantity  of  blood,  increase  almost  suddenly  in  size,  and  thus 
cause  the  erection  of  the  penis. 

The  extremity  of  the  penis  is  called  the  glans,  which,  in  its 
distended  state,  is  large  and  rounded,  and  is  the  counterpart  to 
the  mouth  of  the  uterus  in  the  female,  to  whicli  it  is  applied  in 
the  act  of  copulation.  At  the  extremity  of  the  glans  is  the  mem- 
brane to  the  urethra,  which,  in  some  measure,  projects  beyond 
the  glans. 

At  the  commencement  of  the  urethra,  near  the  neck  of  the 
bladder,  are  found  three  small  bodies,  called  the  prostate  glands, 
one  of  which  is  much  larger  than  the  others.  These  glands 
secrete  a  white  fluid,  or  mucus,  which  mixes  with  the  semen  pre- 
vious to  its  ejection. 

The  penis  of  the  horse,  in  its  flaccid  state,  is  not  usually  seen, 
being  aitc^ther  situated  within  its  sheath,  which  is  formed  by 
loose  folds  of  skin,  reflected  on  the  body  of  the  penis,  so  as  to 
permit  the  ready  prcyection  or  retraction  of  the  organ. 

Within  the  sheath  are  situated  a  number  of  small  glands, 
which  secrete  a  white  odorous  substance,  which  often  collects, 
and  becomes  offensive ;  and  sometimes  insinuates  within  the  ure- 
thra, and  obstructs  the  passage. 

The  teminal  Jiuid,  from  the  place  of  its  secretion  to  that  of  its 
departure  from  the  body,  traverses  a  considerable  length  of 
passage;  that  of  the  urethra  alone  being  nearly  two  feet 

It  is  secreted  by  the  minute  branches  of  the  spermatic  artery, 
whence  it  passes  into  small  tubes  which  convey  it  to  larger  ones, 
which  from  being  assembled  in  the  form  of  network  are  called 
the  rete :  thence  a  still  larger  set  of  tubes,  the  vasa  eflerentia, 
eonvey  it  from  the  testicle  itself  to  the  epididymis.  The 
epididymis,  which  we  have  before  observed  lies  on  the  upper 
part  of  the  testicle,  receives  the  semen  from  the  vas  eflerentia, 
which  unite  at  the  anterior  part  of  the  epididymis,  and  terminate 
io  a  single  duct  several  yards  in  length  when  unwound,  hut  coiled 
up  in  the  small  compass  of  the  large  head  or  nut  of  the  epidi- 
dymis. From  this  part  the  vas  deferens  proceeds,  which,  joining 
the  cord,  enters  the  abdomen  through  the  ring,  and  traversing 
the  pelvis,  conveys  the  semen  to  about  one  inch  posterior  to  the 
neck  of  the  bladder. 

The  Vencvia  Seminalis,  oblong  membranous  bags,  are  supposed 
to  act  as  reservoirs  for  the  semen ;  they  are  situated  in  the  space 
between  the  bladder  and  the  rectum,  and  open  by  means  of

laving  like  it  a  power  of  ei-ection,  and  funiishcd  with  muscles 
for  the  pur|)Ose. 

Anicrior  to  the  cUlorU  and  about  four  inches  from  the  vulrn, 
we  fnid  the  commencement  of  the  passage  to  tbe  bladder,  ibe 
meatus  ui'inarius.  It  is  large  enough  lo  admit  the  finger,  it 
about  two  inches  in  length,  and  passes  downwanls  and  forwanU 
to  the  bladder;  it«  cntmiicc  is  guarded  by  a  m<MnhrMnr,  which 
lie*  upon  it,  and  thus  nets  n¥  a  valve.

upwards,  into  tlie  abdomen,  and  end  in  round  extremities,  to 
which  are  connected  the  lallopian  tubes. 

The  uterus  poesesses  considerable  slrength,  which  is  chiefly 
owing  to  its  thi^  fibrous  coat,  which,  during  gestation,  ponesses 
great  contractile  power.

and  a  half  in  length,  leading  from  the  horns  of  the  uterus  to  the 
ovaria. 

The  Charia  or  female  testicles  are  considerably  smaller  tliati 
the  male  organs,  which  in  shape  they  resemble,  being  about  the 
size  of  walnuts;  they  are  situated  in  the  abdomen,  a  little  ante- 
rior to  the  kidneys,  and  are  loosely  connected  to  the  spine  by 
membrane.  They  are  well  supplied  with  blood  vessels  and 
nerves,  and  snpply  small  ova  or  vesicles,  one  of  which,  during 
copulation,  is  conveyed  through  the  fallopian  tubes  to  the  uterus, 
and  being  impregnated  by  the  aeminal  fluid  of  the  male,  becomes 
the  germ  of  a  new  animal. 

The  operation  of  spaying,  so  often  performed  in  the  pig,  and 
sometimes  on  the  cow  and  mare,  consists  in  making  an  opening 
at  the  flank  into  the  abdomen,  and  introducing  the  finger,  with 
which  the  ovaria  are  brought  out  and  cut  oflp. 

The  Udder  of  the  mare  is  situated  at  the  lower  and  back  part 
of  the  abdomen  between  the  thighs;  in  the  virgin  state  it  is 
exceedingly  small,  but  towards  the  latter  period  of  gestation  en- 
larges considerably,  and  a  few  days  before  parturition  milk  is 
secreted. 

The  udder  is  a  glandular  structure,  well  furnished  wiih  blood 
vessels,  by  which  the  milk  is  secreted,  which  is  then  poured  into 
specific  canals,  which  convey  it  to  the  teats  or  dags,  the  ex- 
tremities of  which  arc  pierced  with  three  small  holes,  for  the 
exit  of  the  milk.  Both  udder  and  teals  are  covered  by  soft 
skin,  generally  of  a  dark  colour.  —  £o.]

OH    THE    FUNCTIONS   OF   THE    GENERATIVE    GROANS,    AND    THE 
GROWTH    OF    THE    FffiTUS. 

[The  purpose  of  the  complicated  structures  which  we  have  de- 
scribed, both  in  the  male  and  the  female,  is  the  preservation  of 
the  species.  For  this  purpose,  it  is  not  only  essential  that  the 
seminal  fluid  should  be  ejected  into  the  uterus,  but  that  tbe  mare 
should  be  in  a  state  fit  to  receive  it.  The  human  female  is  in 
a  state  fit  for  breeding  all  the  year  round;  hut  in  the  mare  this 
state  only  exists  at  the  period  of  horsing,  which  is  generally 
confined  to  the  summer,  and  the  early  part  of  it.  Mares  go 
eleven  months  with  foal ;  but  they  usually  exhibit  the  disposition 
to  copulate,  which  is  well  known  by  the  increased  heat  and 
swelling  of  the  parts  of  generation,  and  the  emission  of  a  while 
fluid,  about  nine  or  ten  days  after  gestation,  and  at  intervals 
afterwards  of  a  few  days  at  first,  and  then  about  three  weeks 
from  this  time ;  the  brood  mare  is  consequently  enabled  to  hreed

by  ilie  presciKe  of  ilie  salacious  female.  'Hie  testicles  are  drawn 
up  anil  the  penis  is  quickly  ereclcd  by  llic  sudtlen  acciimulalion 
ot  blood  in  its  cavernous  subsunce  and  glans,  which  by  tlie 
angle  formed  at  the  root  of  tlic  penis  is  prevctiicd  returning. 
In  llm  state,  the  leap  having  been  taken,  the  penis  enters  llie 
female  parts,  and  tW  glans,  by  succes^vc  cHbrts,  ia  pushed 
against  the  oe  uteri,  to  which  it  exactly  corresponils.  The  fric- 
tion of  tlir  parts  produces  exquisite  pIcaiHirc  to  both  sexes,  at  the 
climax  of  which  the  semen  is  ejected  into  (lie  utfrus  with  con- 
siderable force.  This  done,  the  act  ts  conipletecl  on  the  part  of 
the  male,  the  penis  becomes  llacctd,  and  is  withdrawn,  and  the 
feeling  of  lassitudv  succeeds  the  inten«ily  of  pleasure. 

The  female  often  rejects  the  temeii  shortly  afterwards,  lo  pr^ 
renl  which,  it  is  sometimes  custaitiar>'  to  throw  cold  water  over 
the  loin*  to  diminish  the  excitement  of  the  parts,  and  thus  caiue 
llicm  to  rctnin  tho  prolific  fluid.  Bleeding  Ims  been  somcttmn 
practised  with  (he  snine  view,  and,  it  is  staled,  witii  success. 

When  ttie  mare  is  impregnated,  the  os  uteri  is  closed,  and 
tlH're  is  no  longer  a  dispooition  for  (he  Itorse;  this  rule,  howevtri 
is  not  without  exceptions. 

Tlif  phenomena  which  supervene  in  the  female  uterus  after  a 
SlicccBHful  impregnation  have  been  the  subject  of  much  dispute, 
and  are  siill  mun-ouiidod  with  mystery.  'I'lie  Otaria  arc  found 
to  be  composed  of  vesicles,  or  sacs,  which  contain  a  fluid,  within 
wlitcli  arc  small  bodies  called  ovula,  and  which  un',  indeed,  die 
germs  of  vonng  animals.  Whether  the  seminal  fluid  is  conveyed 
by  the  fallopian  lubes  to  the  ovario,  and  there  impregnates  aii 
ovulum,  as  is  siip|>ose(l,  or  whether  the  vesicle  bursts  indepen- 
dently of  the  copulative  act,  and  is  then  conveyed  to  tli«  uterus 
theru  to  be  impref^naied,  or  not,  we  cannot  determine. 

Tlie  ovulum,  being  impregnated,  is  ternteil  (lie  ovum,  aitd  on 
de])arting  from  the  ovarium  leaves  a  scar  behind,  which  ia  called 
a  airpnx  luleum. 

The  impregnated  ovum,  «oon  after  its  arrival  in  th«  ulen», 
becouK^  firmly  attaclicd  to  this  body,  prior  to  which  n  quantity 
of  blood  is  determined  to  the  uterus,  by  which  a  tubitancc  re- 
tenibliiig  lymph  is  secreted,  which  furnishes  not  only  a  lining 
membrane  for  the  uterus,  but  also  fur  the  ovum  itself.  Tlie 
former  is  termed  llie  decichious,  iind  ihc  lalUT  the  rellecti^  coat; 
and  each  of  them  soon  becoming  abtiixlanily  fiirni»lic*l  with  blood 
vcKM-ls,  they  toj;etl»-r  are  c.illed  the  I'lncrnta,  and  the  ftcius  is 
thereby  »upplied  witli  noui'inhincnt.  The  vessi-ls  of  tlie  mother, 
and  (liose  nf  the  fcetus,  do  tvot  communicate  with  each  otlier  by 
any  direct  clianiiel ;    but  it  is  sup[>osed  that  the  fietnl  ves»ela 


FUNCnONB  OF  THE  OEMERATtVE  OROANa,  ETC      87 

derive  nourishment  and  purification  by  a  sort  of  imbibition  from 
the  mother's  blood. 

The  ovum,  on  leaving  the  ovaries,  is  furnished  with  a  mem- 
brane, called  the  Amnios,  which  afterwards  increases  in  size,  and 
furnishes  a  liquid  in  which  the  fcetus  floats,  comparativety  free 
from  danger,  and  in  all  the  ease  and  luxury  of  an  hydraulic  bed. 
It  is  supported  in  its  situation  by  the  umbilical  cord,  or  navel 
string,  which  is  nearly  three  feet  in  length,  and  is  composed  of 
the  blood  vessels,  and  a  canal  communicating  with  the  bladder, 
and  proceeding  from  the  navel  of  the  fcetus,  and  passing  to  the 
deciduous  membranes  of  the  mare,  litis  canal  is  called  the 
urachus,  and  serves  to  convey  away  the  superfluous  water  that 
the  Ibetal  bladder  would  be  incapable  of  containing. 

The  circulation  of  the  blood  in  the  fcelus,  it  is  evident,  must 
be  very  different  from  that  after  birth.  Nourishment  is  not 
afibrdM  by  the  stomach,  bile  is  not  secreted  by  the  liver,  nor  is 
the  blood  purifled  by  the  Itmgs :  these  organs  are  only  supplied 
with  nourishment  sufficient  for  their  own  support  and  increase. 
The  arteries  belonging  to  the  maternal  portion  of  the  placenta 
terminate  partly  in  veins,  and  partly  in  exhalent  surfaces  :  from 
these  exhalent  surfaces,  the  minute  branches  of  the  umbilical 
veins  of  the  fcetus  absorb  blood  in  a  comparatively  red  and 
purified  state:  they  convey  this  blood  into  the  fecial  circulation 
through  the  vein,  which,  in  the  animal  after  birth,  is  wholly  en- 
g^ed  in  supplying  the  liver.  It  will  thus  be  seen  that  the 
umbilical  veins  convey  red  blood,  and  the  umbilical  arteries  black 
blood,  contrary  to  the  usual  custom.  The  blood  from  the  um- 
bilical veins,  as  well  as  the  lower  part  of  the  body,  enters  both 
sides  of  the  heart  at  once,  and  a  small  portion  is  thence  sent  into 
the  lungs  from  the  right  ventricle,  whilst  the  largest  portion  is 
distributed  to  the  system  from  the  left  ventricle. 

There  is  a  communication,  too,  between  the  aorta  and  the 
pulmonary  artery,  by  which  the  blood  not  required  by  the  lungs 
IS  sent  into  the  system  through  the  aorta.  It  will  thus  be  seen  that 
the  heart  of  the  fcetus,  though  double  in  its  construction,  is  single 
in  its  office;  and,  in  this  respect,  is  very  analogous  to  the  single 
heart  of  some  cold-blooded  animals.  No  sooner,  however,  does 
the  animal  breathe,  than  the  right  side  of  the  heart  has  an  inde- 
pendent office  to  perform,  and  the  communications  before  spoken 
of  are  closed  up.  —  Ed.]

action  necessary  for  the  production  of  the  youiij;;  animal,  llie 
question,  hovrever,  is  not  to  be  decided  by  anatomy,  or  physioloni 
but  only  by  the  evidence  of  a  number  of  practical  results.  'iTie 
germ  of  the  future  offspring  is  certainly  supplied  by  the  female; 
but  still  the  form  and  qualities  may  he  the  eflect  of  tJte  male, 
just  as  the  dticlilc  wax  receives  vvhalevcr  impression  tlie  stamp 
may  be  calcuhtcd  lo  produce,  wla-dicrthc  head  of  a  prince  or  that 
of  a  ]>easant.  We  must  therefore  look  only  to  facts,  lo  decide 
the  point.  It  is  a  matter  of  i>ome  impurlaneein  thebreeding  of 
animals  to  have  as  correct  views  as  possible  on  this  subject,  for 
it  is  too  frc(|iieully  the  ciim-  thut  either  one  parent  or  the  otlwr 
b  entirely  disri'garded  iti  ilie  choice,  and  the  result  is  a  weakly, 
Ifiiongrel,  or  bad-shaped  animal.  In  crossing  the  breed  of 
'  animals  I  think  it  will  he  found  that  tlic  oflBpring  turns  mwlly 
after  the  sire  twlh  in  shape  and  in  size.  The  common  mule 
begotten  by  the  male  ass  out  of  the  marc  certainly  discovers  a 
much  Mroiiger  affinity  in  shape  and  size,  and  in  disposition  toO| 
10  his  plebeian  sire,  than  to  liis  more  arisloeralic  dam.  The 
lengthv  ears,  the  narrow  foot,  the  coarse  head,  tlie  light  and 
wiry  limbs,  the  comparatively  insensible  skin,  arc  all  derived 
from  tike  aM,and  even  lii»  sixc  is  more  accordant  to  the  sire  ilian 
to  llie  dam.  It  must  be  borne  in  mind,  that  the  large  Spuiisli 
mules  that  we  oceasioiially  see  are  begotten  by  asses  of  great 
silt!.  In  the  breeding  of  sheep,  it  is  found  tliat  (he  qualities  of 
the  ram  preponderate  over  tlmse  of  the  ewe,  a  tact  which  is  well 
illiislraled  hy  the  crois  between  tlie  South  Down  ewe  and  Uie 
|.CotMwold  or  Leicester  ram,  in  which  the  progeny  very  neariy 
iipprnactM»  the  Cotswold  both  in  size,  length  of  wool,  and  seneru 
apiK-anince.  In  hordes  it  is  surprising  wliat  large  animals  pony 
marcs  Mill  breed  when  covered  by  horses  much  laigt^r  than  ihcm- 
selvof,  and  it  is  rarely  the  case  that  a  large  roomy  inai-c  will 
produce  n  colt  that  will  reach  her  own  size,  if  put  toasmallatidlion. 
There  are  of  course  exceptions,  but  such  is  the  general  rule. 


TBE    PHINCIPLES   AND    PRACTICE    OF   BREEDING.  89 

From  these  facts,  I  think  we  are  justified  in  concluding  that 
the  influence  of  the  mare  is  superior  to  that  of  the  horse,  and  that 
the  ofispring,  in  shape,  size,  and  general  qualities,  turn  more  after 
the  father  than  the  mother. 

This  fact,  however,  will  bj'  no  means  justify  that  total  indif- 
ference as  to  the  qualities  of  the  mare,  so  generally  pursued, 
particularly  by  farmers.  When  a  mare  is  unfit  for  every  other 
purpose,  she  is  generally  considered  worth  something  for  breeding, 
whereas,  in  many  cases,  it  would  be  more  prudent  and  economical 
to  destroy  the  poor  brute,  than  suffer  her  faults  and  misfortunes 
to  become  hereditary.  For,  although  the  influence  of  the  horse 
may  be  greater  than  that  of  the  mare,  yet  the  bad  qualities  of 
the  latter  are  just  as  likely  to  be  hereditary  as  those  of  the  sire ; 
and  indeed  any  constitutional  defects,  such  as  a  scrofulous  dis- 
position, are  more  likely  to  be  derived  from  the  mare  than  the 
horse,  inasmuch  as  the  intimate  connection  between  the  maternal 
and  fcetal  system  is  considerable  before  birth,  and  is  kept  up  after- 
wards by  means  of  the  milk.  It  must  not  be  forgotten,  too,  that 
amongst  mares  and  horses  kept  for  breeding  the  proportion  of 
bad  mares  is  greater  than  of  bad  horses.  A  horse  is  rarely 
preserred  entire,  and  used  generally  as  a  stallion,  unless  he  has 
some  excellences ;  whilst,  as  before  observed,  it  is  very  frequently 
the  case  that  the  only  claims  a  mare  has  to  the  embraces  of  a 
horse  are  her  unfitness  for  every  other  purpose.* 

A  bad  mare  will  scarcely  ever  produce  a  good  colt,  however 
excellent  the  horse  may  be ;  and  although  a  very  superior  stallion 
maybe  introduced  in  a  country  where  the  qualities  of  the  horses 
are  bad,  and  the  benefit  may  be  immediately  perceptible,  yet  it 
takes  some  years  and  several  generations  before  the  character 
of  the  stock  is  materially  changed. 

The  Arabs  of  the  desert,  we  are  told,  prize  their  mares  in- 
finitely beyond  their  horses,  and  while  they  part  from  the  latter 
freely,  yet  nothing  can  induce  them  to  give  up  their  favourite 
mares.  To  this  scrupulous  attention  to  the  female  is  doubtless 
chiefly  owing  the  fact  of  their  preserving  their  race  of  horses  free 
from  degeneracy,  and  in  such  great  perfection  for  so  many  years. 
While  tney  preserve  good  mares  they  cannot  have  bad  horses, 
whereas  had  they  allowed  degeneracy  to  creep  in  amongst  their 
mares,  the  qualities  of  their  horses  could  not  have  supplied  the 
deficiency. 

It  is  a  question,  however,  whether  they  would  not  have  im- 
proved their  race  of  horses  still  more,  if  they  had  bestowed  more 
of  that  scrupulous  attention  on  the  sire  which  they  pay  so  ex- 
clusively to  the  dam.     And  although,  from  the  impossibility  of

why  he  put  a  little  plain,  though  Fast  marc,  to  the  horse,  he  replied  she  was 
very  poor,  and  he  thought  it  would  do  her  good.

getting  the  choicest  Arab  mares,  we  cannot  reduce  their  powen 
to  a  fair  comparison  with  our  own,  yet,  from  the  great  ease  with 
wliich  our  second-rate  liorscs  have  beat  the  Arabs,  some  of  them 
perhaps  the  own  brothers  of  their  favourite  mares,  I  am  in- 
clined to  think  that  if  even  their  choicest  mares  were  entered  for 
tliosc  of  our  stakes  confined  to  the  feminine  sex  alone,  we  should 
find  that  the  pride  of  the  desert  would  be  unable  to  wrest  the 
laurels  from  our  Crucilixes  or  Black  Besses,  and  tbat  the  winner 
of  the  Oaks  would  still  remain  of  English  blood. 

Breeding  horses  is  generally  considered  an  unprofitable  branch 
of  a  farmer's  business,  bnt  this,  I  take  it,  is  in  great  measure 
owing  to  the  want  of  judgment  displayed;  for,  certainly,  keep- 
ing an  animal  till  he  is  four  or  five  years  old,  taking  all  the 
risks  to  which  young  stock  are  exposed,  and  then  realising  a 
price  ranging  between  201.  and  30/.,  will  most  assuredly  leave  a 
balance  on  the  unfavourable  side  of  the  profit  Mid  loss  account 
1  am  here  not  alluding  to  those  large  breeders  who  make  it  their 
principal  business,  having  eictensive  pastures  applicable  for  no 
other  purpose,  hut  to  those  agriculturalists  who  cannot  keep  their 
colts  for  less  than  three  or  four  shillings  per  week.  To  this  de- 
scription of  farmers  breeding  cart  horses  is  more  profitable  tfaaa 
luicks,  as  the  colts  come  into  work  at  two  and  three  years  c^d, 
and  thus  earn  their  keep  at  this  early  age,  and  if  tbey  are  large 
and  promising  often  realise  high  prices  by  the  time  they  are  five 
years  old.  Although  more  judgment  has  been  displayed  in  this 
stock  than  in  that  of  a  better  breed,  yet  there  is  still  much  room 
for  judicious  improvement.  By  using  a  horse  as  a  stallion  better 
bred  than  those  generally  used,  many  advantages  are  secured, 
without  any  proportionate  drawbacks. 

The  advanta^fes  arc,  by  slightly  reducing  the  weight  we  gain 
an  improvement  hi  the  action,  so  much  so  that  a  pace  of  four 
miles  an  hour  will  be  easier  executed  than  three  miles  an  honr 
by  the  heavier  horse.  By  getting  more  breed  a  greater  d^^ree 
of  nervous  energy  is  obtained,  and  the  horse  is  less  likely  to  tire, 
and  will  consequently  do  more  work. 

For  common  agricultural  purposes,  there  is  no  horse  so  handy 
as  one  about  15  hands  or  a  little  more;  and  where  the  land  is 
not  particularly  heavy,  and  the  principal  object  of  the  &rmer  is 
to  get  useful  horses  for  his  own  use,  he  cannot  do  better  than 
breed  these  little  active  animals,  which,  by  a  judicious  attention 
to  the  qualities  of  the  sire,  and  the  dam,  lie  may  obtain  with 
such  a  degree  of  speed  in  the  walk  as  to  do  half  as  much  work 
again  as  the  heavy,  hairy-legged  sort. 

When,  however,  the  farmer  intends  selling  off  his  stock  after 
working  them  two  years,  so  as  to  realise  large  prices  for  the 
London  market,  it  is  then  essential  that  a  much  greater  me 
should  be  attained,  viz.  from   16  to  17  hands,  together  with  a 


THE   PBINCIPLEE    AND    PRACTICE    OF   BBEEDINO.  91 

disposition  to  carry  plenty  of  flesh,  for  the  Londoners  will  not 
buy  unless  a  horse  is  fat. 

These  purposes,  however,  may  still  be  eSected  without  losing 
sight  of  the  principle  we  have  advocated,  that  of  improving  the 
breed  ;  for,  by  selecting  large,  active,  good-shaped  cart  mares, 
and  by  putting  them  to  a  powerful  half-bred  Btallion  (better  bred 
than  he  looks),  we  may  secure  size  and  shape,  at  the  same  time 
have  substance  and  flesh  enough  to  please  the  metropolitan  eye, 
and  to  obtain  as  high  prices  as  any  that  are  sent  to  the  London 
markets.  I  have  myself  seen  many  of  this  breed  whom  no  one 
would  condemn  as  too  light  for  any  purposes  of  draught.  I  do 
not  like  the  plan,  however,  of  putting  a  cart  mare  to  a  thorough- 
bred horse,  as,  generally  speaking,  these  extremes  are  not  equally 
mixed  in  the  oflspring,  but  are  harshly  conjoined ;  for  we  often 
see  them  with  the  Iq^  of  the  sire,  and  the  carcass  of  the  dam, 
the  two  extremes  meeting,  but  not  mingUtig,  in  the  young  animal. 

In  breeding  half-bred  horses,  so  as  to  realise  a  profit,  the 
principle  to  be  kept  in  view  is  to  produce  an  animal  that  will  at 
four  or  five  years  old  realise  50/.  or  60/,  j  to  do  which  no  greater 

Xnse  is  incurred  than  in  breeding  an  animal  of  one  half  this 

in  the  first  place,  then,  we  have  to  inquire  what  sort  of  animal 
it  is  that  realises  thb  high  price.  They  are  principally  of  two 
kinds,  hunters  and  carriage  horses.  By  hunters,  however,  we 
do  not  mean  any  animal  that  can  gallop  fast  over  a  light  country ; 
but  one  that  can  carry  a  heavy  weight  in  deep  ground,  well  up 
to  bounds  when  the  scent  is  good,  and  the  pace  proportionate. 
For  this  purpose  we  require  breed  and  substance  in  the  highest 
degree  the  two  qualities  can  be  combined  together.  The  horse 
should  be  as  nearly  as  possible  16  hands,  with  a  deep  chest 
and  barrel ;  not  too  short  in  the  back,  but  with  strong  loins  and 
quarters;  good  fore-arm  and  legs;  light  head  and  neck,  but  the 
latter  not  too  short.  These  qualities  are  more  easily  obtained 
in  a  smaller  horse,  but  this  will  not  do  if  a  good  price  is  expected ; 
there  must  be  a  large  frame  to  carry  weight,  and  this  can  be  ob- 
tained if  the  breeder  will  get  the  right  sort  of  mare,  which  can 
be  done  by  not  sparing  a  few  pounds. 

The  mare  then  should  behalf-bred,  and  as  near  as  possible  16 
hands;  not  under  15^  nor  over  16^,  unless,  in  the  latter  case, 
the  other  qualities  are  very  excellent.  She  must  not  be  blind  or 
half  blind,  unless  from  an  accident,  as  the  diseases  of  the  eye  are 
very  hereditary.  If  she  is  lame,  we  must  assure  ourselves  that 
it  has  not  been  produced  by  natural  defect.  We  must  take  care 
that  she  is  not  too  long  and  oblique,  or  too  short  and  upright,  in 
tbe  pasterns ;  or  knuckling  at  the  knees  or  fetlocks,  or  small 
under  the  knee. 

If  she  be  washy  or  light  carcassed,  although  as  fleet  as  the

walked  over),  he  is  the  sort  of  horse  for  getting  taluablc  liuntenu 

By  selecting  such  a  sire  and  dam  as  these  just  mentioned, 
tliere  is  every  probability  of  breeding  animals  of  value;  but  1  am 
not  averting  tliat  such  a  niare  as  1  have  stated,  and  no  otlier, 
shovild  be  used  for  breeding.  The  breeder  may  possess  a  mare 
nearly,  or  quite  thorouph-bred,  and  such  a  one  may  prove 
valuable  for  breeding.  In  this  case  the  danger  is  in  getting  ibe 
slock  too  small  or  too  light:  and,  gcncrallv  speaking,  it  will  not 
be  prudent  to  use  a  thorough- bred  stallion  for  such  a  mare. 
He  may  he.  three  parts  bred,  out  with  great  substance;  and  if  be 
has  been  signalised  in  the  annaU  of  hunting  or  sleeple^cluuii^ 
so  much  ibo  b<>ller.  If  the  mare  be  small  and  tbo rough-bred,  tbe 
hone  -ibould  be  of  still  greater  size  and  substance,  and  may  be 
only  hnlf-bri-d,  providing  his  action  is  good. 

I  liave  known  some  very  clever  animals  bred  in  ibis  way; 
whereas  if  a  tliorough-bred  horse  had  been  used,  the  chancn 
would  have  been  that  tbe  offspring  would  be  small,  weedy,  and 
valueless. 

In  breeding  carriage  horses  an  equal  degree  of  care  must  be 
employed,  as  in  breeding  hunters.  .-Vnd  indeed  more  scrupulous 
attenuon  must  be  paid,  so  as  to  avoid  ihoio  defccis  that  offend 
tile  eye,  which  in  butilers  may  be  looked  over  or  atoned  for  by 
ttie  possession  of  other  first-rate  qualities:  for  instance,  if  a 
carriage  horse  has  a  short  neck,  however  excellent  his  ottier 
QualilKS  may  bo,  be  will  not  realise  a  high  price.  Some  years 
since,  tail  leggy  Cleveland  Ixiy  horses,  17  bands  high,  were  all 
tbe  ra^;  but  at  the  present  day  the  public  taste  is  improved, 
and  preference  is  now  given  to  an  animal  of  les*  lieight,  but  of 

f;rcater  strength  and  symmetry,  ranging  between  15^  to  10} 
lands.     Such  an  animal  must  be  lengthy  without  being  light 


THE   PRINCIPLES    AND    PRACTICE    OF   BREEDINO.  93 

carcassed ;  the  shoulders  oblique,  and  not  loaded,  but  with  high 
withers;  the  neck  must  be  long  and  arched,  and  the  head 
carried  high.  He  should  be  well  ribbed  up,  without  being  short, 
and  he  must  not  be  gooee-rumped,  or  ragged-hipped.  His 
action  must  be  good,  neither  too  high  nor  too  low,  but  rather 
tending  towards  the  former  than  the  latter  extreme. 

There  must  be  little  or  no  white  about  the  legs,  and  the  best 
colour  is  bay ;  next  to  this  brown,  unless  a  grey  can  be  obtained, 
which  is  as  good,  or  better  than  either. 

To  obtain  such  an  animal,  we  must  take  care  that  neither  the 
sire  nor  the  dam  possess  any  of  those  defects  that  we  would 
avoid  in  the  oSspring,  The  mare  should  he  a  good  carriage 
mare,  and  if  rather  heavy,  the  horse  may  be  thorough-bred,  but 
not  the  one  we  would  select  for  getting  hunters,  but  one  more 
lengthy.  If  the  mare  is  well  bred,  the  horse  must  not  be 
thorough-bred,  but  as  near  as  may  be  consistent  with  plenty  of 
substance. 

The  two  descriptions  of  horses  which  I  have  mentioned  are 
those  to  which  the  attention  of  the  breeder  should  be  principally 
directed  with  a  view  to  realising  good  prices,  but  there  are  other 
sorts  of  mares  that  may  be  bred  from  with  great  advantage,  such 
OS  clever  hacks  and  cobs,  and  handsome  ponies.  Indeed  when- 
ever a  mare  has  superior  qualities  without  striking  defects,  she 
may  be  advantageously  used  for  breeding,  providing  the  right 
sort  of  horse  is  selected  as  sire.  A  little  three-pa rt&-b red  mare, 
however,  should  not  be  put  to  a  thorough-bred  horse,  as  the 
produce  would  probably  be  weedy,  and  of  little  value,  whereas  a 
BtalUoD  of  more  substance  and  less  breed  would  probably  get  a 
clever  hack.  Superior  cobs  are  very  saleable;  and  if  quick, 
strong,  and  handsome,  will  often  realise  large  prices,  being  in 
demand  for  elderly  gentlemen.  It  is  necessary  that  they  should 
be  good  walkers  and  trotters;  unless,  therefore,  the  mare  is 
good  in  these  paces,  we  should  not  breed  from  her ;  nor  should 
we  if  she  shies,  as  this  vice  is  generally  incurable  and  heredilary. 
If  the  mare  be  a  very  strong  cob,  we  may  put  her  to  a  ihorough* 
bred  horse,  but  as  compact  a  one  as  can  he  found ;  but  if  the  marc 
is  light,  we  must  select  a  cock-tail  for  a  stallion,  but  one  well 
bred,  and  compact.  Some  of  these  cobs  are  remarkable  trotters ; 
and  this  quality  may  be  readily  produced  in  the  offspring,  by 
taking  care  that  both  sire  and  dam  excel  in  this  pace.  Pontes 
are  susceptible  of  considerable  improvement ;  in  the  forests  where 
they  run  wild  for  several  years,  a  thorough-bred  horse  would 
greatly  improve  the  race  by  infusing  more  blood  into  the  stock; 
taking  care  not  to  allow  very  faulty  mares  to  breed. 

In  endeavouring  to  breed  superior  stock,  the  chance  of  realising 
large  prices  is  such  as  to  compensate  for  every  attention  jiaid  to 
the  colt,  which  should  be  welt  fed  for  several  years,  and  indeed

The  great  superiority  of  our  race  horses,  and  tbe  perfrction 
wliicl),  in  niajiy  ivspecis,  they  have  reached,  is  owing  to  several 
circumstances,  but  to  none  more  than  to  t)te  outritiouv  diM 
whicli  they  get  from  their  earliest  years,  lite  effect  of  tbii 
nuirilious  feeding  is  to  produce  a  considerable  de^'elo{>enient  of 
muKclr,  and  it  must  be  apparent  to  every  observer  how  early 
tilt*  lltoroiigli-bred  horse  becomes  furnished;  as  much  so,  indtvd, 
at  two  years  old,  as  a  grass-feil  hoi-se  at  four.  It  is,  in  my 
opinion,  owing  to  being  thus  com-fcd  so  early,  that  they  are 
etinbK'd  lo  surpass  in  s|)eed  and  bottom  the  descendants  of  their 
|wrent  bri'vd. 

In  breeding  horsca  for  the  turf,  the  principle  kept  in  view  is 
to  put  the  fastest  mare  to  the  faitte»t  Uonc ;  Uitic  it  is  only  the 
winnerit  of  the  untti  stakes  that  arc  afterwards  used  for  gelliiu 
racing  stock,  lliis  principle  is  no  doubt  pretty  correct ;  only  it 
>nuM  be  obscrred,  tlmt  in  selecting  the  particular  horse  for 
a  favourite  mare,  there  are  other  circumstances  to  be  bome 
in  mind,  iliat  sliould  often  induce  t»s  to  give  tlic  preference  to 
OIK'  horse,  that  might  have  proved  himself  flighlly  inferior  in 
•peed  to  lirs  rival.  The  circumstance*  to  be  chiefly  regarded 
•re,  first,  the  poiisession  of  qualities  in  the  hurs<-  of  whicb  iho 
nwire  may  be  deficient :  secondly,  the  iid>nni«;re  of  a  good  con- 
stitution; and  tbii'diy,  t)ic  posscKtion  of  good  fore  legs.  The  6r*t 
is  M>  apjiareiu  as  tciircely  to  need  any  remark ;  for  us  it  must  be 
the  case  that  a  marc  that  has  proved  lier  excellence  for  racing  will 
be  sure  to  be  employed  for  bieethng,  whatever  other  de^ts  she

matter  of  great  importance,  not  only  because  it  is  the  surest 
means  of  imparting  a  good  constitution  to  the  offspring,  but  also

mares !  In  these  cases,  it  is  generally  found  that  the  horses  have 
only  appeared  on  the  turf  one,  or  at  most  two  years,  and  their 
running  has  generally  been  very  uncertain  ;  whilst  the  sires  of 
numerous  winners  have,  generally  speaking,  proved  not  only 
their  superior  speed,  but  also  the  strength  of  their  constitution, 
by  the  truth  and  honesty  of  their  running,  and  the  number  of 
their  races. 

3rdly.  The  possession  of  good  legs  in  the  sire  is  a  matter  to 
which  less  attention  is  generally  fiaid,  than  to  either  of  the  other 
points  mentioned,  and  yet  it  is  one  of  great  importance,  even  in 
a  pecuniary  point  of  view ;  for  although  the  speed  of  the  animal 
does  not  depend  on  the  goodness  of  the  fore  legs,  yet  the  power 
of  enduring  training  does,  for  in  nine  cases  out  of  ten,  when  a 
colt  becomes  lame  in  training,  it  is  from  disease  of  the  fore  legs. 
We  cannot  wonder  at  this,  when  we  consider  that  the  fore  legs 
have  to  sustain  the  whole  weight  of  the  animal  increased  by  the 
momentum  derived  by  speed,  and  connect  this  fact  with  the  early 
age  at  which  these  exertions  are  demanded,  and  the  consequently 
weak  and  unfit  state  of  the  parts.  How  essential  it  is,  then, 
that  these  parts  should  be  as  strong  as  nature  can  make  them, 
and  yet  how  common  it  is  for  them  to  be  altogether  disregarded  ! 
If  greater  attention  were  paid  to  the  state  of  the  fore  l^s,  it  is 
reasonable  to  expect  that  there  would  not  be  so  many  horses 
fail,  either  in  training  or  in  their  early  races,  as  there  are  at 
present,  and  consequently  there  would  be  a  great  saving  of  that 
h*nitles3  expense  which  is  now  frequently  incurred  in  training 
horses  that  break  down  before  they  become  winners.  —  Ed.]

DISEASES    OF   THE   MORSE. 

CHAP.  XX r. 

OM    INFLAMMATION. 

[Inflammation  is  usually  considered  as  a  disorder  of  the  blood- 
vessels, but  we  can  best  understand  its  nature  by  considering  the 
phenomena  with  which  it  is  connected.  If,  then,  any  extern^ 
part  of  the  body  present  the  symptoms  of  nodling,  redaeu,  and 
paht,  we  may  justly  consider  it  iu  a  state  of  inflammation.  The 
swelling  is  to  be  attributed  in  the  first  place  to  the  fulness  of  the 
vessels  of  the  parts,  but  after  a  while  an  effusion  takes  place  front 
the  surfaces  of  these  vessels,  and  thus  keeps  up  or  increases  the 
enlargemenL  The  redness  is  owing  partly  to  the  greater  quan- 
tity of  blood  in  the  arteries  of  an  inflamed  part;  but  priocipally 
(o  the  fact  that  the  small  capillary  vessels,  which  in  a  state  of 
health  may  not  contain  red  blood,  are  now  enlarged,  so  as  to 
admit  the  red  particles.  The  pain  of  an  inflamed  part  is  owing 
to  the  pressure  of  the  enlarged  vessels  on  the  nerves  of  sensation, 
but  this  symptom  is  not  always  present — only  indeed  where  the 
distention  is  sufficient  to  produce  severe  pressure,  or  where  the 
part  is  more  largely  furnished  witli  nervous  flbres. 

A  part  in  a  state  of  inflammation  is  therefore  more  abundantly 
supplied  with  blood  than  in  a  state  of  health,  and  afler  a  time 
the  vessels  themselves  become  enlarged,  and  in  many  cases  nev 
vessels  are  formed  in  a  short  space  of  time ;  as  was  proved  by  the 
celebrated  Mr.  Hunter,  who  froze  the  ear  of  a  rabbit,  and  then 
suddenly  thawed  it,  so  as  to  produce  great  inflammation,  when 
it  was  found  that  the  ordinary  vessels  were  enlarged,  new  ones 
formed,  and  the  substance  of  the  ear  thickened. 

The  capillary  vessels  in  an  inflamed  part  become  distended 
oflen  beyond  the  power  of  contraction,  and  are  partially  ob- 
structed, which  may  be  noticed  when  the  conjunctiva  of  the  ^e 
is  inflamed ;  vessels  which  were  not  perceptible  become  visibly 
and  are  loaded  with  red  blood,  which  they  did  not  contun 
before.  And  after  the  inflammatory  action  has  subsided,  many 
of  the  small  vessels  continue  for  some  time  full  of  red  blood, 
from  being  in  a  state  of  debiiily,  and  unable  to  contract  on  their 
contents,  which  they  are  assisted  in  doing  by  the  use  of  external 
stimulants.

as  the  lungs,  the  bowels,  or  the  brain,  may  become  the  seat  of 
inflammation,  and  ma;  threaten  the  destruction  of  (he«e  parta, 
and  itie  liCe  of  ilie  animal  itself. 

The  infiammation  may  be  confined  to  a  Email  locality,  sucli  as 
a  tinew  or  a  joint,  or  it  may  extend  to  varioiu  parts,  and  iiule«d 
involve  llic  whole  nyslem.  Strictly  xpi-aking,  nowerer,  inflam-

general  irritation  is  produced,  and  the  circulation  is  disturbed 
and  hucried.  'ITiese  Uiler  symptoms  are  denominated  Fever, 
and  may  exist  eitlter  widi  local  inflammation,  or  without  it ;  but 
this  we  must  consider  preaently. 

Inflammation  may  thus  be  confined  to  a  particular  part,  and 
produce  no  const itutioual  ditlurbance^  or  it  taaj  produce  n 
gcnoral  fewer  dirotigh  tin'  Jtystem. 

These  efleeli  d«|)end  partly  on  tho  degree  of  inflammation 
exi«tiog,  and  |wrtlv  on  the  irritability  of  tlie  part  aflected.  A 
sinew  or  joint  moderately  intlamed,  produces  no  constitutional 
irriiiit  ion,  but  when  severely  afTcttwllbe  symptoms  of  general  firvcr 
are  excited.  This  effect  takes  place  more  easdy  in  hui-ses  of  an 
irritable  temperament  than  in  others,  and  is  produced  through 
the  medium  of  the  nervous  system.  Tbc  nerves  of  the  inflamed 
part  are  painfully  alTcelwl ;  this  irritjilion  is  conveyed  to  the 
Drain,  whence  it  in  diffiiscd  througltont  tlw  tiyKtem,  af&cting  some 
parts,  however,  more  dian  others,  and  producing  different  effects 
in  different  animals.  The  heart  is  quickly  afTecied  by  this 
nervotia  irritation,  and  it  becomes  excited  to  quicker  and  nrare 
forcible  action,  and  thus  wc  have  the  quick,  hard,  inflammatory 

£ulse.  The  stomach  is  generally  (not  always)  affcciod,  and  we 
Bve  eoncpqiiently  nausea  or  want  of  appetite,  one  of  ihe  most 
important  symptom*  we  liave  to  asiist  us  in  the  treatment  of 
disrosc  in  the  liorse.  When  the  action  of  the  heart  is  tliu*  in- 
juriously exciied,  the  circulation  becomes  disturbed,  aiid  we  luive 
»  n^undancy  of  blood  in  some  parts,  and  a  diuiinution  in  others, 
and  thus  wc  frMiuetitly  lind  the  i-xti'vniitirs  cold,  and  tlie  mouth

In  this  way  local  inflammation  may,  and  ff«quenUy  does, 
produce  geru>ral  fever,  and  it  is  also  the  Aict  tliat  general  fever 
Eonietiretes  excites  local  inflammation. 

Infliimmation,  although  generally  regarded  as  a  disease,  and 
correctly  too,  is  yet  an  eflorl  of  nature  to  n-lii-ve  herself  from

Inflammations  near  the  surbce  of  the  body  arc  generally 
produced  either  by  violence  from  without,  as  in  wounds,  bruiio,

All  organs  are  rarely  equally  |)erfecl ;  one  part  b  generally  weaker 
than  another,  and  therefore  more  predisposed  to  disease :  and 
thus  the  same  cause  may  produce  diflerent  diseotes  in  diflerent 
liorses,  verifying  the  old  proverb^  "'Htc  w<-ake»l  goes  to  the 
wall."  One  fertile  cause  of  inflammation  is  n  redundancy  of 
blood  in  the  system;  but  this  e.ause  may  pro<ltice  in  one  none 
inflammation  of  the  lutigx,  in  another  inflammation  of  iho  liver, 
ill  a  thini  that  of  tlie  braiii,  according  to  the  susceptibility  of  (he

ihorc  is  an  alteration  in  its  character,  which  is  of  still  greater  im- 
portance. Some  horses  have  naturally  a  much  stronger  pulse 
than  others,  which  it  would  bo  useful  toascertain,  if  possible;  but 
lhi»  i«  ran-ly  the  rase. 

The  pi'incipnl  varieties  in  the  kind  of  pulse  are  a  soft,  hard, 
aironff,  weak,  liill,  opprc^ncd,  and  intermittent  puW.  A  hone 
may  have  naturally  citlier  a  »lrong  or  weak  pulse,  according,  in 
a  great  measure,  to  the  vigour  of  hts  constitution.  Under 
diKMC  we  may  have  the  above  varieties  in  the  pulse  dilTerently 
combined.  A  full  puUc  denotes  an  abundance  of  blood  in  ilic 
system,  a  strong  pulse  a  vigorous  action  of  the  hcarf,  and  if  wiili 
these  stales  we  nave  aUoa  quickened  action,  copious  blood-letting 
in  demanded.  A  hard  pulse  is  considered  diaracierisiic  of  in- 
flainnintion :  we  then  bleed,  in  onler  to  produce  a  soft  puUr. 
When  the  veueU  are  exceedingly  full  there  is  sometimes  an  op- 
pressed pulse,  which  demands  copious  bleeding.  A  weak  state 
of  the  pulse  Ibrbids  bleeding,  and  often  requires  stimulanu;  this 
slate  ol  the  pulse  is  often  present  in  influenza,  being,  at  the  same 
time,  greatly  quickened.  It  is  also  the  case  towni-ds  the  faul

head. 

The  TVta/mmt  of  JnJIammalioH  will  mainly  depend  on  the 
object  wc  have  in  view,  whether  to  seek  for  reioluiion,  or  any  of 
the  other  icrminations  we  have  mentioned.  In  inflammatory 
anections  of  vital  part£,  our  treatment  should  be  such  as  to  bring 
about  the  restoration  of  the  organs  to  their  normal  slate  :  in  fact, 
resolution.  For  this  purpose  Inrj-v  blood-lettings  are  generallj 
liad  recourse  to,  and  with  great  advnnU^e.  Ity  general  bli-eding 
we  subtract  blood  from  the  system,  und  consequently  there  is  lesa 
blood  wnt  to  the  tnflaiiH-d  part,  the  capillary  viiM-la  of  which 
may  thus  have  iiiT»e  to  relieve  themselves. 

The  beneht  of  general  bleeding  \%  much  agisted  by  abstract- 
ing blood  rapidly,  mid  from  a  large  orifice;  a  sudden  check  » 
thus  put  upon  tiK- circulation,  whiclii  thongh  of  short  duration,  is 
vei  m  great  service  in  ucule  inflammalion.  In  esses  of  active 
inflammation,  the  best  guide  oh  to  the  qtiantity  of  blood  to  be 
abstracted  is  obtaiiKtl  by  observing  its  effect  on  the  pulse,  and  on 
tlw  mouth.  We  ihould  bleed  until  ihe  liiiier  feels  considerably 
cooler,  mid  the  former  becomes  altered  in  its  character,  becoming 
softer  and  weaker,  though  generally  quicker. 

The  state  of  the  blood  \a  a  very  uncertain  criterion,  and  should 
have  but  little  influence  over  our  treatment.  This,  however, 
may  be  observed,  tttat  when  it  presents  a  buffy  coat,  there  is 
ustially  a  capability  for  bearing  bleeding,  and  the  contrary  when 
tl»c  blood  is  very  black,  supposing  it  is  drawn  from  a  large  ori- 
fice. Local  bleeding  for  internal  inflammations  can  seldom  be 
practised  in  the  horse. 

Although  bleeding  is  the  sheet-anchor  in  acute  inflammation, 
oilier  remedies  are  of  importance. 

Purffiaff,  though  useful  in  some  inflammations,  is  lo  be  con- 
demned when  the  chest  is  nlTected ;  a*,  by  sympathy  betwi-cn  ihc 
lungs  and  the  bowels,  the  irritation  of  the  latter  by  purgation 
has  a  very  injuriotis  cHect  on  the  Kings,  boidei  lowering  tlw 
system  to  a  grem  extent.  It  ia,  however,  desirable  to  obtain  a 
iDodcrately  relaxi-d  »tate  of  the  bowel*. 

IXtirfsiM  is  of  much  greater  benefit :  by  determining  a  greater 
qnantity  of  blood  to  the  kidneyn,  a  portion  is  diveried  from  an 
inflamed  pan,  and  tlie  system  is  also  uniuaded  by  iho  increfwed 
secretion  of  urinv.  Medicines  are  often  adminiKteied  having  n

enabled  to  determine  blouil  to  the  skin  by  means  of  the  wanii

diseaso.  BhI,  from  the  targe  :(ixe  of  our  jialientH,  and  their

part,  we  apply  cold  lotions ;  but,  if  our  object  be  to  encourage 
suppuration,  we  have  recourse  to  warm  poultices  and  foment- 
ations. 

In  severe  strains,  warm  fomentations  are  often  employed  first 
with  advantage,  and  are  succeeded  by  cold  applications;  we 
thereby  relieve  the  inflamed  part,  first  by  means  of  perspiration, 
and  afterwards  by  evaporation. 

Cbunter-trrttenff,  such  as  blisters  and  setons,  are  employed 
after  the  infiammation  has  abated ;  their  beneficial  effect  is  pro- 
duced by  withdrawing  the  blood  from  the  inflamed  part  to 
another  and  a  healthy  locality.  If  employed,  however,  in  too 
early  a  stage,  they  often  increase  the  inflammation  they  are  in- 
tended to  abate.  —  Ed.]

[HAVitia  largely  noticed  the  subject  of  Inflammation,  we  sliall 
have  but  little  to  say  on  that  of  Fever.  It  is,  however,  usually 
considered  of  two  kinds — Symptomatic,  or  Inflammatory  Fever  ; 
and  Sinqiie  continued  Fever,  or  Synochue. 

The  former  we  have  already  alluded  to,  under  the  head  of 
.Inflammation.     In  an  inflammatory  disease,  when  the  pulse  is 
full  and  ft^uent,  the  mouth  hot,  and  the  membrane  of  the  nos- 
tril injected,  we  say,  there  Is  much  fever ;  and  the  presence  of 
these  symptoms  usually  guides  us  in  the  abstraction  of  blood. 

In  such  cases,  generally,  though  by  no  means  invariably,  the 
Mood  presenu  a  bu%  coat,  which  is  usually  considered,  and 
often  with  justice,  an  evidence  of  the  propriety  of  blood-letting. 
Where  there  is  much  general  fever,  accompanied  by  local 
inflammation,  such  as  from  an  open  joint,  or  externa)  injury, 
there  is  a  greater  proportion  of  fibrine  In  the  blood  than  in  a 
state  of  health ;  and  so,  likewise,  in  acute  rheumatic  affections. 
■  Simple  continued  fever  is  a  welt  recognised  disease  in  man ; 
bat,  in  the  horse,  its  existence  has  been  often  denied.  It  is, 
however,  the  fact,  that  we  have  occasional  cases  of  fever  in  the 
horse,  without  any  symptoms  of  local  inflammation,  and,  in  such 
cases,  we  rarely  find  a  bufly  coat  presented  by  the  blood,  and 
tbere  is,  genendly,  an  inability  for  bearing  large  venesections. 
Sucb  cases  are  often  ushered  in  by  shivering  fits,  and  which 
sometimes  recur  during  the  progress  of  the  complaint.  In  some 
epidemic  diseases,  particularly  in  the  influenza,  so  prevalent  in 
1836  and  1840,  ^e  symptoms  of  fever  were  strongly  marked, 
and  often  without  any  local  inflammation.     In  other  cases,  local

ommendfO  the  practice. 

Stomach  stajigcrs,  though  not  a  primarr  affection  of  the  brain,

[I^ibicH,  or  Hydrophobia,  is  a  disease  of  the  nervous  «y>tem,

it  tnay  manifest  itself  at  vnrioits  periods,  from  one  month  to 
several  after  the  bite.  Mr.  Youait  observes  in  bis  lectures.  Vet. 
vol.  X.,  '*  Tlw  earliest,  and  perliapa  the  moat  decisive,  symptom  of 
the  near  approach  of  rabies  in  the  horse,  is  a  spasmodic  move-

Close  following  on  tbis,  or  conlcmporancoua  with  it,  is  the

Treatment,  when  once  tl>e  complaint  has  manifested  itself,  if 
perfectly  useless :  tlie  aninial  should  tlierefore  be  shot. 

Preventive  treatmenl.  however,  may  be  employed  wilh  success, 
if  we  can  find  out  the  bitieii  part.  It  eliould  as  soon  as  possible 
be  excised  completely  witli  the  knife,  or  the  luitar  caustic  freely 
applied  to  the  wound  and  repealed.  I  have  operated  with  the 
caustic  on  various  horses  bitten  by  rabid  dogs,  and  ttotic  of  tiiem

"  The  posi-morltm  ap|>earance!»,"  says  Mr.  Youatt,  "  of  rabiet 
in  tl>e  horse  are,  to  a  considerable  degree,  uncertain.  Nothing

of  this  affection,  hemiplegia  and  paraplegia.  The  former  is  a 
tiarnlysisof  one  side  of  the  body,  the  latter  of  the  bind  extremities, 
rile  former  is  extremely  rare  in  the  horse,  and  there  are  not 
above  one  oi'  two  cases  on  record.  One  ease  is  rehitcd  by 
Mr.  Hull  in  vol.  v.  of  the  Veterinarian.  Thcsymplom*  comeon

Paraplegia,  or  loss  of  power  of  the  hind  extremities,  is  much 
more  frequent,  and  generally  arises  from  some  sudden  injury  of 
ihe  spinal  cord,  produced  by  keeping  luck  a  loaded  waggon, 
or  slipping  up,  or  a  severe  strain  in  leaping.  It  may  also  be 
produced  by  some  tumour  pressing  on  the  nerves  which  suuply 
tlie  hind  extremities,  and  is  then  gradual  in  its  approach.  When 
ibia  ii^uiy  is  produced  by  an  accident,  the  vertcbriE  of  the  luins

accidents  are  comparatively  frequent  in  the  army,  where  they 
arise  from  bringing  young  horses  suddenly  on  their  haundies: 
horses  in  this  state  are  said  to  be  chinked  in  the  back.

section, laxative  and  febrifuge  medicine,  and  the  npplieiilinn  of 
warm  sheep  akin*  at  first  to  the  loins,  and  succeeded  by  H'Eons, 
blisters,  or  a  blistering  ebargt'. 

There  is  a  debase  in  livdia  very  iilmilar  to  tliia,  called  Kmnrte. 
It  is  described  by  Mr.  Huglies  in  the  Veterimirian,  who  says,  "  1 
am  of  opinion,  that  i)>e  kumree  b  a  weakness  in  the  hind  ex- 
tremities, produced  by  pressure  on  the  nerves  going  to  these 
pans;  or  it  is  asymptom.or  rather  a  termination, of  inllammation 
of  the  bruin,  or  it*  membranes,  wliicli,  in  ibo  human  subject, 
would  produce  hydrocephalus  ;  but  probably  from  ibe  utruclureof 
tlie  lior^,  (be  anruniulntion  of  tlie  elluM-d  fluids  i.i  prevented,  and 
they  pass  down  within  the  tliecoe  of  (he  medulla  spinalis.  This 
inflammation  of  t)ie  brain  is  of  a  mild  or  subdued  form ;  were  it 
greater,  it  would  induce  phrenitis.  TIic  causes  of  it  arc  (K-al, 
nidilen  dianges  from  heat  to  cold,  and  from  cold  to  hint,  and 
plethora.     Severe  blows  on  the  head  nmyid^o  occasion  it." 

Mr.  Twining,  in  a  paper  prenenU'd  lo  the  Culcutta  Mi-dicid 
Society,  and  copied  inio  the  Veterimirian,  attributes  the  kuniree 
to  animalcuhe,  either  about  the  vertebra;  or  the  cellular  leMure 
connected  with  tliem  :  and  Captain  Wyatt  says,  that  he  hasoOen 
been  pre«ent  during  the  ilisscction  of  liorsc»  that  bad  dtii]  of

even  five  weeks,  before  l)ie  ilw^iue  was  subdued.  As  a  further 
encour«^emeiU  to  fiilure  palkiHrc  and  p«raevenuice  in  the  ireat- 
tiient  of  tliiK  dflii^-rout  divorder,  I  sludl  notice  a  case  related  by 
LCibton,  from  wliicli  it  appears  tlmt  not  only  medicine,  bat 
llBoiirishmetit  also,  niay  i>e  administered  in  the  form  of  clysten. 
[  "  The  liorse  was  seized  rather  suddenly  with  this  kind  of  coa- 
'  vulsion  (locked  jaw),  vrhieli  w*a?  first  oluervtsl  a*  he  Wat  Iradrilg

now;  lunii-d  otii,  hiseyrs  fixed  and  iunimvable,  witli  nil  ilteotI)«r 
■igiis  that  usually  attend  this  disorder ;  and  when  he  came  to  tlie 
trough  could  not  reach  the  water  liecause  of  the  cramp  and  stiffs 
neas  in  his  neck,  and  tvlien  it  nas  l>eld  to  him  in  a  pad  he  could 
not  drink,  though  he  showed  an  eagerness  fur  it ;  his  mouth 
heiag  shut  up  so  close  (hat  it  was  scarce  possible  to  put  a  knife 
between  his  leeth.  Wc  found  it  impracltcablu  to  ndminisUT  any 
kind  ofmnlictne,  till,  by  nibbing  bis  cheeks,  jaws,  temple*,  and 
his  whole  neek  for  a  considerable  time,  wt?  made  a  shift,  with 
great  diUlcuhy,  to  thrust  down  pan  ofa  calomel  ball  on  the  end 
of  a  small  slick,  and  then  to  pour  into  hi§  ito^irils  a  very  small 
portion  of  a  strong  cephalic  drink ;  thinking  hy  itiat  means  to 
convt^  the  ball  ilowiiwurd  into  his  stomach,  which,  however,  had 
but  little  elTeci,  any  fui-tlier  than  this,  that  he  had  not  sach  sud- 
den fits  and  agitations  as  1  have  (cen  in  oiliers  in  the  like 
circumstances,  but  continued  more  quiet;  neither  did  hi»  fever 
increase,  an  ununlly  hap[K-ns  when  the  disorder  is  gaining  ground. 
But  all  tills  while  his  mouili  continued  so  much  shut  that  he 
could  neiilirr  rat  nor  drink  for  tliree  weeks,  only  by  continually 
rubbing  his  Jaws  and  neck,  he  would  sometimes  make  a  shifi  to 
suck  about  a  handful  of  scalded  bran,  or  sometimes  a  little  oat- 
meal moistened  with  warm  n-aler,  but  in  so  small  a  quantity  that 
it  is  [KiKsihIe  lie  might  have  starved,  had  not  other  methods  been 
I  taken  to  ki-ep  liim  alive.  I  have  often  observed  thai  the  forcing 
^tlie  jaws  open  by  violent  mCAns  puts  a  horse  into  such  agunies 
that  it  rather  increiL«i-s  than  abates  the  symptoms,  and  theretiire 
1  contriTed  to  give  him  bulb  hie  food  and  physic  bv  the  funda- 
ment, through  a  pipe  fourteen  inches  long ;  by  which  he  seemed 
1  [o  receive  great  benefit,  for  we  could  pei'ceive  the  tymptomi 
nbate  daily.  His  Hanks  grew  more  quiet,  he  stood  tnorv  still, 
and  free  from  sudden  fits  and  stnitingK,  all  which  symptoms  are 
usual  in  (he  incnfiLxe  iiM\  continuitme  of  iliis  disorder.

by  way  of  diet,  three  or  four  quarts  of  milk  boiled  with  oatmeal

up,  their  natural  molian  tieing  inverted  for  tliejiurpoHe:  and  as 
lie  scarcely  ate  more  in  tlii-ee  vreeks  than  was  siiffieient  to  support 
him  one  day,  ttiere  caii  be  iio  doubt  that  lie  derived  mucb  nou- 
ri&liment  from  these  clysters.  lie  had  two  men  coiintauitly  lo 
look  after  him,  who  Itaid  orders  to  rub  liis  whole  body  often, 
which  greatly  helped  to  relax  bis  skin  and  remove  the  crampitics.'i 
of  his  muscles:  and  although  he  had  not  for  the  Rr^t  fuicni^fiit 
recovered  llie  use  of  his  jaws,  yet  we  observfd  liim  daily  to  move 
with  lees  stilTiieaJ,  and  often  to  lick  the  matiger  as  if  lie  craved 
for  food.  He  also  breathed  with  less  difficidly,  and  liad  several 
other  good  signs.  I  now  determined  to  try  the  effect  of  an 
opium  clyster ;  therefore  I  di^olved  half  an  ounce  of  crude  opium 
in  one  of  his  clysters,  which  was  followed  with  these  circum- 
stances—  that  tlie  horse  soon  lay  down,  he  began  to  point  his 
ears  backwai'ds  and  forwards,  and  could  move  his  neck  pretty 
freely,  and  his  mouth  wa;  so  fur  at  liberty  lliat  he  took  bis  drinks 
with  liKltf  or  no  difficulty,  and  could  eat  bay  and  bran  sufficient 
to  sitslain  him,  lie  likewise  moved  hb  whole  body  so  readily 
that  we  could  walk  him  an  hour  every  day.  That  I  might  follow 
up  this  good  elfect  of  the  opium  clyster,  I  gave  him  some  davs 
after  1  oi.  of  Matthew's  pill,  which  contains  about  two  druclima 
of  opium,  and  the  same  quantity  of  assalVelida.  This  was  given 
by  the  itioutli,  in  a  ball,  and  repeated  the  following  day.  lie 
now  recovered  daily,  and  took  his  drinks  only  twice  a  week ;  and 
as  soon  as  he  recovered  his  flesh  was  gently  purged,  after  which 
he  got  |>erfectly  well," 

Gibson  attribviles  tliis  disorder  to  ihc  irritation  of  bolt*,  or 
other  worms  in  tlie  stomach.  He  disapproves  of  mirgativcs 
(t^iilier  as  drenches  or  as  clysters)  and  bleeding.  Mo<Wii  prac- 
titioners do  not  reckon  bolts  among  the  causes  of  locked  jaw, 
which  is  most  commonly  brought  on  by  the  causes  before?  noticed. 
1'he  great  benefit  derived  from  the  opium  clyster  should  be 
carefully  recollected.  Mr,  Wilkinson  examined  four  horses  llmt 
died  under  his  care,  and  found  the  nia  niaicr  of  the  spinal 
marrow  inflamed,  and  the  marrow  it»ell  of  a  dark  colour.  Tlig 
uia  mater  of  tlie  brain  was  likewise  inflamed  in  a  slight  degree. 
When  locked  jaw  comes  on  after  docking  or  nicking,  he  applies 
fomentations  lo  the  uil,  and  afierwanU  dresses  the  wuuntl  with 
digestive  ointment.  I  cured  one  case  of  locked  jaw  by  blistering 
the  back  from  the  withers  to  the  tail,  and  giving  opium  ami 
camphor — which  we  found  great  difficulty  ni  giving.  Every 
now  and  tl»en  a  little  gruel  was  given.  By  persevering  in  ibi« 
treatment  the  jaws  gradually  relaxed,  and  in  twenty-four  bourn 
the  horse  was  able  to  eat  hay.

rccomineiKU  blistering  ihe  abdomen  extensively,  to  produce  i 
counter-action  in  the  system.  He  goes  6o  far  as  to  consider  tlial 
a  diseased  slate  of  the  digestive  organs  is  invariably  the  primary 
cause  in  idiopRthic  tetanus. 

Mr.  Karltifk  relates  four  sueces&ful  case*  treated  by  large  and 
rcjK-Htpd  bleeding,  purgatives,  opium  and  camphor  injections,  aiid 
blisters  in  eoriie  casefl  to  the  spine,  in  others  to  the  abdomen. 

Mr.  Karkcck  considers  the  disease  to  be  very  frequent  in  the 
west  of  Cornwall,  owing  to  its  being  almost  surrounded  by  thr 
sea;  and  believes  idiopalliic  much  more  curable  than  irauiaslic 
tetanus.  —  Ed.] 


String  Halt. 

Thin  disnise  is  characterised  by  the  sudden  and  ■piiBlfilft 
mmnicr  in  which  the  hock  is  bent,  the  leg  at  the  Minte  tHofr 
being  carried  very  high.  It  is  not  ii  liinicno$K,  for  ihcre  h  ntf 
dropping  on  the  other  leg,  and  it  cannot  be  felt  by  the  rklrr  ltk« 
hocK  lameness;  but  it  is  an  unecjunl  action  of  tlie  mnsdes, 
arising,  most  probably,  from  some  alFectioti  of  the  nervm.  In 
some  cases  it  is  said  the  Etiflf  joint  lia-i  been  found  diitrosnl,  and 
in  others  the  spine  itself  has  been  affected.  Hut  a  few  years  ago 
I  had  the  pleasure  of  spending  a  day  with  the  late  Dr.  .lenner  at 
Dcrkley,  when  he  informed  me  that  string  halt  depended  upon 
u  disease  of  tbe  spine,  and  showed  me  several  vertebra?,  wnidi 
afforded  a  proof  of  it. 

[Mr.  t".  Spooner,  the  talented  assistant  nrofessor  at  (he  Veteri- 
■  nary  College,  has  clearly  shown  that  in  the  majority  of  cases  U 
'is  owing  to  disease  of  the  ;frpat  sciatic  nerve,  which  supplies  tlic 
muscles  of  the  hind  extremity.  Nen-ous  energy  is  thus  inipor> 
frctly  sup[^ied,  and,  consequently,  tlie  most  powerful  muscle* 
act  the  most.  It  is  often  connected  with  disease  of  llie  liock, 
and  is  sometimes  preceded  by  it.     Treatment  is  useless.  —  En.]

CHAP.    XXIV. 

DISEASES    OF    THE    CHEST     AND     AIR-PASSAGES. 

Inflammation  of  the  Lungt.  —  Pneumonia, 

[Some  years  since,  when  the  earlier  editioos  of  this  vork  were 
printed,  it  was  customary  to  class  all  ihe  diseases  of  the  chest 
under  one  head — inflamed  lungs;  and  the  same  treatment  was 
prescribed  for  alL  Later  research,  however,  has  considerably 
altered  this  opinion ;  and  although  it  is  an  undeniable  fact  that 
inflammatory  afl^tions  of  the  different  contents  of  the  chest  are 
ofien  extremely  complicated  with  each  other,  yet  in  numerous 
instances  the  symptoms  of  the  different  affections  are  so  dis- 
tinctly marked,  that  it  would  be  absurd  to  deny  their  separate 
and  distinct  existence.  Thus,  without  making  any  distinctions 
but  what  are  warranted  by  observation  and  experience,  and  are 
necessary  for  the  judicious  employment  of  remedial  measures, 
we  shall  have  to  consider— 

Pneumonia,  or  inflammation  of  the  substance  of  the  lungs. 

Pteuritis,  or  inflammation  of  the  membrane  covering  the  lungs 
and  lining  the  chest. 

Bronchitit  and  Trachitis,  or  inflammation  of  the  mucous  mem- 
brane lining  the  bronchial  tubes  and  the  trachea;  besides 
Catarrh^  or  inflammation  of  the  membrane  lining  the  nostrils  and 
the  throat. — Ed.] 

Pneumonia,  or  PeripTteumony. 

[Even  this  disease  often  presents  itself  in  different  forms ;  some- 
times running  its  course  and  ending  fatally  in  less  than  twenty- 
four  hours,  and  in  others  extending  to  four  or  five  days.  In  the 
former  variety  the  lungs  after  death  appear  black,  in  fact  gorged 
with  blood ;  and  this  used  to  be  considei'ed  as  a  state  of  mortifi- 
cation,  and  it  was  common  to  say  of  such  a  horse,  that  "  his 
lights  were  rotten  as  a  pear;"  and  if  the  horse  had  recently  been 
purchased  of  a  dealer,  and  an  action  were  brought  for  the  reco- 
very of  the  value  of  the  horse,  the  black  appearance  of  the  lungs 
was  generally  considered  as  a  sufficient  proof  that  the  animal 
was  rotten  and  unsound,  and  the  dealer  was  cast  in  consequence; 
whereas  the  congested  appearance  of  the  lungs  ought  to  have 
been  considered,  in  the  absence  of  any  appearance  to  the  con- 
traiy,  as  a  proof  of  the  recent  production  and  rapid  nature  of  the 
disease. 

Sucb  appearance  of  the  lungs  is  generally  afforded  when  a 
borse  dies  after  over-exertion  in  the  chase,  or  from  being  vio- 
lently driven  when  not  in  proper  condition.

(lies,  as  it  were,  from  suiTocaiion,  in  tlie  course  of  twelve  to 
twenty-four  hours.  Mr.  Percivall  dislingiilshe*  this  disease  from 
pnoutnonia,  and  designates  it  coiuftttwn  oflht  lumji,. 

When  blood  is  abstracted,  it  is  almost  iiivaiiiibly  finmd  of  a 
very  dark  colour,  which  is  owing  to  the  gorged  >lale  of  the  lungi 
preventing  the  purification  of  the  blood  from  Liking  place. 

Trutr  Itt/lammaeiun  of  the  Limat,  wht-n  its  symptoms  arc  un< 
subdued,  usually  terminates  fatally  in  the  course  of  four  or  five 
days;  though  sometimes  it  gets  into  a  sub-acute  state,  and  lingen 
on  for  several  weeks. 

Its  first  symptom  is  usually  a  diminution  or  Iocs  of  appetite, 
hut  in  some  cases  n  troublesome  cough  may  precede  tbis  want  uf 
ap]H-lilv  for  several  ilays. 

'I'lie  pulse  and  respiration  are  soon  affected,  both  becoming 
exceedingly  quick;  tlie  pulse  from  iiixiy  to  one  hundred  in  a 
minute,  and  the  hreailiing  either  almost  as  fast,  or  otherwise 
laborious  nnd  difficult. 

The  pulse  may  Ix-  either  full,  and  strong  or  hai-d,  or  olbcrwixc 
weak  and  almost  imuori-'eptible  ;  in  ilie  latter  ease  our  prognosis 
is  more  unfavourable  than  in  the  former.  'I'tie  legs  and  ears 
are  usually  cold  and  tlie  mouth  hot,  and  tlie  membrane  of  tJie 
nostrils  and  eyelids  intensely  red.  In  some  cases  ihore  is  a 
cough,  in  others  none  whatever;  and  often  when  there  lia*  been 
a  congh  before,  it  ceases  as  tlie  inflammation  becomes  more  in- 
tense. 

Ttie  l>owels  are  generally  inclined  to  be  costiv^  and  after  the 
disease  ban  existed  for  some  time^  the  dung  is  coated  with 
mucus. 

Some  insight  into  the  nature  and  extent  of  the  disease  may  be 
obtained  by  what  is  called  atnetiflalion. 

On  applying  the  car  to  the  sides  of  the  cheat,  when  the  animal 
!s  in  a  nealtby  state,  we  nutici'  a  murmuring  sound,  difficult  to 
be  described,  Imt  readily  beard.     'Hiis  souod  is  produced  by  the 


DISEASES   OF   THE    CHEST   AND    AIR-PASSAGES.  117 

air  rushing  into  the  air  cells,  and  is  much  greater  in  the  young 
than  in  the  old  subject.  When  the  lungs  are  partially  indurated, 
the  cells  being  filled  up,  there  is  at  that  part  an  absence  of  the 
usual  munnur,  and  an  increase  of  it  elsewhere.  This  result 
sometimes  attends  the  presence  of  fluid  in  the  chest.  Afler  exer- 
cise the  murmur  is  increased ;  and  if  in  a  state  of  rest  the  sound 
at  one  part  is  increased,  and  not  at  another,  the  latter  part  is 
probably  in  a  state  of  disease. 

The  principal  indication  of  a  diseased  state  of  the  lungs  is  de- 
rived from  a  sound  called  bronchial  respiration,  and  somewhat 
resembles  the  sound  made  in  sawing  wood.  It  is  occasioned  by 
the  air  rushing  in  and  out  of  the  large  hronciual  tubes,  there 
being  some  impediment  to  its  passage.  This  sound  is  heard  in 
peripneumony  and  in  acute  pleurisy,  and  more  particularly  when 
both  diseases  are  combined. 

There  are  various  other  alterations  of  sound  noticed,  but  they 
are  of  minor  importance,  and  less  readily  detected ;  they  may, 
however,  be  found  described  in  Mr.  Percivall's  work  on  the  Dis- 
eases of  the  Chest,  &c.,  where  the  essay  of  M.  Deiafond  on  the 
subject  b  translated. 

The  employment  of  auscultation  is  much  assisted  by  percussion. 
Od  tapping  the  chest  sharply  with  the  knuckles,  the  sound 
dicited,  if  the  lungs  are  indurated,  or  there  is  water  in  the 
chest,  will  be  much  more  dead  than  in  a  healthy  state ;  whilst,  on 
the  other  hand,  when  the  lungs  are  emphysematous,  as  in  broken 
wind,  the  sound  will  be  augmented. 

The  Treatment  of  this  disease  must  depend  on  the  particular 
stage  in  which  we  may  And  it,  and  must  be  modified  by  the 
peculiar  symptoms  that  may  be  present.  In  the  first  place,  let 
us  suppose  a  horse  is  blown  in  hunting ;  ridden  till  nature  is  ex- 
hausted, and  the  animal  can  go  no  further.  In  such  case  the 
lungs  are  in  a  congested  state,  and  the  proper  changes  in  the 
blood  cannot  take  place ;  the  breathing  is  of  course  accelemied 
to  the  greatest  d^ree,  and  the  pulse  quick  and  weak,  and  pro- 
bably imperceptible.  If  the  vein  be  opened,  the  blood  flows 
with  difficulty,  and  is  exceedingly  dark  and  thick.  In  such  case 
it  is  of  litde  use  to  abstract  blood  until  the  pulse  becomes  per- 
ceptible, and  our  best  plan  is  at  once  to  administer  a  stimulant. 
A  botde  of  wine,  administered  in  the  hunting  iield,  has  in  many 
a  case  proved  of  essential  service,  and  in  some  instances  saved 
tbe  animal.  Two  ounces  of  spirit  of  nitrous  ether,  administered 
in  a  pint  of  warm  ale  or  water,  is  still  better :  its  efiect  will  be 
to  equalize  in  some  degree  the  circulation,  and  to  rouse  the  nerv- 
ous system;  and  soon  after  its  administration  wc  shall  pro- 
bably And  the  pulse  becoming  fuller  and  more  perceptible.  In 
this  state  we  should  abstract  blood — as  much  as  we  can  obtain 
without  producing  fitinting.     The  same  method  of  treatment

effects  succeed  its  employment.  Indeed,  in  ciiM'S  of  iii(bimnm> 
tion,  il  is  better  to  find  the  blood  preseniinj;  a  bulTy  eojit  than 
otherwise;  unK«^  it  should  be  likewise  of  a  thick  muddy  aspect, 
which  is  a  bB<l  sign. 

AMieim:*.  —  AUbough  bleeding  most  be  our  prinei|«il  remedy, 
yi-i  w<>  must  not  despise  other  assistance.  Ahliuugb  it  is  dnir- 
rable  in  some  degn-e  lo  unload  the  bowels  we  must  take  care 
not  10  purge,  for  if  wc  do  so,  deatli  will  probably  follow  ;  and  from 
HytnpBihv  between  the  bowels  and  other  iwris,  a  much  smaller 
do»e  will  act  on  them  than  in  a  state  of  hi'«lih.  If,  therrforoi 
the  iMweU  are  not  coslive,  no  aperient  will  be  requln-d;  but  if 
ollierwise,  we  should  administer  an  inji-clion,  after  backraking, 
and  give  from  one  to  two  diaclims  of  aWs  or,  what  is  still  belter, 
about  a  pini  of  linseed  oil ;  lo  liiis  mild  n[H-ri<-nt,  which  should 
not  be  repealed,  we  may  add  a  drachm  of  lartanxed  antimony, 
lhM«  drachms  of  nitre,  and  one  of  digitalis.  It  is  a  dangerous 
praelio'  to  administer  small  doM-s  of  aloes  until  the  bowels  are 
acted  on,  as  by  this  lime  a  sufficient  quantity  may  accumutatc  in 
the  system  to  do  iri-e])arab]e  mischief.     The  nitre,  digitalis,  and

antimony  may  be  repeated  three  times  the  first  day,  and  twice 
the  second. 

Mr.  Percivall  recommenda  half  a  drachm  of  white  hellebore 
twice  a  day  instead  of  the  digitalis.  It  is  a  powerful  medicine, 
and  lowers  the  pulse  by  producing  nausea.  It  requires  to  be 
given  with  caution,  under  the  eye  of  the  practitioner,  and  its 
effecte  carefully  watched.  Mr.  Mavor  advises  two  drachms  of 
extract  of  belladonna  as  a  sedative.  I  have  employed  both  these 
medicines,  and  can  speak  to  their  good  effects. 

CoutUer-irritatum. — After  the  urgency  of  the  symptoms  have 
been  in  some  measure  relieved  by  bloodletting,  counter-irritation 
may  be  very  serviceable  in  preventing  change  of  structure  from 
taking  place.  A  blister  is  to  be  preferred,  and  should  be  applied, 
as  recommended  by  Mr.  Percivatl,  to  the  breast,  in  preference  to 
the  sides,  as  it  is  much  more  likely  to  act  in  the  former  muscular 
situation  than  in  the  latter.  In  Mtal  cases,  a  blister  will  scarcely 
ever  produce  any  effect ;  and  this  symptom  is  therefore  justly 
regarded  as  one  of  the  most  unfavourable  that  can  possibly  occur. 
If  the  case  be  protracted,  or  takes  on  a  sub-acute  form,  rowels 
aod  setons  may  be  useful,  as  well  as  blisters. 

The  diet  in  inflammation  of  the  lungs  should  consist  of  bran 
mashes,  hay,  carrots,  or  green  food ;  and  care  should  be  taken 
that  the  horse  is  not  restored  to  his  usual  diet  until  the  inflam- 
matory symptoms  have  entirely  ceased. 

The  body  should  be  kept  tolerably  warm  by  clothing,  and  the 
legs  encased  in  flannel  bandages ;  their  warmth  having  been  pre- 
viously restored  by  hand-rubbing,  assisted  by  the  application  of  a 
liniment,  composed  of  four  parts  of  oil,  one  of  spirits  of  turpen- 
tine, and  one  of  hartshorn,  which  should  be  rubbed  in  as  often 
as  they  become  cold. 

I(  is  of  great  importance  that  the  horse  should  be  allowed  to 
breathe  tlie  purest  and  the  coolest  air;  for  which  purpose  he 
should  be  turned  into  a  loose  box,  well  ventilated,  and  in  the 
summer  he  may  be  turned  into  a  paddock  with  advantage.  —  Ed.] 

Svb-acute  Pneumonia. 

[When  inflammation  of  the  lungs  takes  on  a  sub-acute  form, 
either  from  the  beginning  or  after  an  acute  attack,  our  treat- 
ment, though  conducted  on  the  same  principles  as  that  before 
mentioned,  must  be  less  active  in  its  nature.  The  symptoms  are 
more  obscure,  and  demand  more  tact  and  discrimination :  the 
breathing  is  less  disturbed,  the  pulse  not  so  quick,  the  appetite 
not  so  much  impaired;  and  yet  fatal  mischief  may  be  going  on 
under  this  insidious  form,  and,  if  not  checked,  may  end  in 
death. 

The  bleeding  should  be  less  extensive,  but  more  frequent  than

added. 

When  eS'usion  had  evidently  taken  place,  he  recommended  the 
operation  of  paracentesis,  or  tapping. — Ed.] 

[_Hi/(trothorax, 

As  tlie  deposition  of  water  in  the  chest  is  termed,  although  an 
effort  of  nature  to  relieve  inflammation,  is  yet  generally  attcniled 
with  a  fatal  termination. 

Tbe  only  chance  of  relief  is  afforded  by  an  operation  called 
paracentesis,  or  tapping,  which  consists  in  plunging  an  instru- 
ment called  a  trochar  between  the  ribs  into  tlic  cavity  of  tlio 
chest,  and  leaving  the  canula,  or  tube  which  encases  the  trochar, 
and  withdrawing  the  latter,  by  which  an  exit  is  afforded  to  the 
fluid  contained  within  the  chest  through  the  canula. 

Tbe  best  situation  for  the  operation  is  between  the  eighth  and 
ninth  ribs,  and  near  the  cartilages;  and  the  skin  should  bo  pre- 
viously drawn  liRhtly  forwards,  by  which  means  the  opening  will 
be  closed  after  the  operation.  It  should  be  performed  on  bolh 
sides  of  the  chest,  and  may  be  repeated  several  timcN,  and  diu- 
retic and  tonic  medicine  should  be  given  at  the  same  time. 

Although  the  majority  of  cases  in  which  this  operation  has 


123  DISEASES  OF   THE   BORSE. 

been  practised  have  ended  fatally,  yet  there  are  KTeral  Buccns- 
ful  cases  on  record,  —  sufficient  to  justify  its  adoption  when  there 
is  a  reasonable  presumption  of  the  presence  erf"  water  in  the  chest. 

This  is  denoted  by  the  sudden  cessation  of  the  violence  of  the 
symptoms  at  first,  and  an  amendment  of  the  appetite;  but  as  the 
water  increases,  the  respiration  becomes  still  more  embarrasied, 
and  very  frequently  a  spontaneous  purging  ensues.  On  applying 
the  ear  to  the  chest  the  natural  respiratory  sound  is  lost;  and  oo 
striking  the  chest  it  no  longer  sounds  hollow,  but  dead. 

The  Symptoms  of  hydrotliorax,  however,  are  by  no  means 
always  the  same — they  principally  depend  on  the  cause.  It 
may  succeed  intense  inflammation  of  the  lungs  and  the  pleun, 
or  sub<acute  or  chronic  inflammation  of  these  parte.  The  symp- 
toms may  either  nearly  subside  as  the  water  is  secreted,  and  the 
cose  present  altogether  a  flattering  appearance,  or  otherwise  un- 
favourable appearances,  though  modified,  may  still  exist-— £d.] 

[^Complicated  Ciues.  Although  we  have  spoken  of  pnenmonia 
and  pleurisy  aa  two  distinct  diseases,  and  although  the  symptoms 
of  each  are  distinctly  marked,  yet  it  is  still  the  fact  that  they  are 
very  frequently  combined  togeUier;  and  then  the  symptoms  may 
cither  denote  the  preponderance  of  the  one  disease  over  the 
other,  or  otherwise  tliey  may  be  so  nearly  balanced  as  to  render 
the  symptoms  altogether  obscure. 

The  Treatment  of  these  complicated  coses  must  be  conducted 
on  the  same  principles  as  before  detailed ;  modified,  however,  by 
the  leading  symptoms. 

It  may,  however,  be  observed  that  these  complicated  cases  are 
more  frequently  fatal  than  simple  affections  either  of  the  pleura 
or  the  substance  of  the  lungs.  They  rarely  present  the  same 
activity  in  the  symptoms,  but  are  usually  more  protracted  in 
their  progress,  and  more  deceitful  in  their  character. —  En.J

BRONCHITIS.— TRACHITIS.  —  INFLAMMATION  OF  THE  DRONCHIAL 
PASSAGES   AM>    WINDPIPE. 

[The  membrane  which  lines  the  bronchial  tubes,  as  the  air  pass- 
ages of  tlie  lungs  are  termed,  as  well  as  that  which  aflbrt^  on 
internal  covering  for  the  larynx  and  trachea,  is  termed  a  mucous 
membrane,  and  ia  very  liable  to  inflammation.  When  thus  in- 
flamed, the  disease  is  termed  Bronchitis,  Trachitis,  and  Laryn- 
gitis, according  aa  the  hroncliia-,  the  trachea,  or  the  larynx  bears 
the  brunt  of  the  attack.     Theic  parts  are  sometimes  separately 


BROMCHITI8,    TRACHITI8,    ETC.  123 

diseased;  but  more  frequently  they  are  affected  simultaneously, 
though  not  perhaps  in  the  aame  degree,  or  to  the  same  extent. 

There  are  two  forms  of  this  disease,  each  distinctly  marked, 
the  acute  and  the  sub^ocute ;  the  latter  being  perhaps  the  more 
frequent. 

The  former  is  an  extremely  dangerous  disease,  and  very  fre- 
quently proves  fata!.  This  is  owing  partly  to  the  great  extent 
of  membrane  diseased,  and  the  difficulty  of  affecting  it  by  our 
treatment,  siid  partly  to  the  obscurity  of  its  symptoms,  and  the 
insidious  nature  of  its  approach,  whereby  it  has  often  existed  to 
B  great  extent  before  attention  has  been  called  to  iL 

It  may  be  produced  by  exposure  to  cold  or  sudden  changes  of 
temperature,  there  being  a  predisposition  in  the  part  to  become 
af^ted. 

It  more  frequently  occurs  in  the  autumnal  and  winter  seasons, 
but  particularly  in  the  former,  and  during  the  prevalence  of 
wet  weather. 

The  Symptotm  are  at  first  ver}'  obscure :  a  cough,  a  staring  coat, 
and  slight  impairment  of  the  appetite,  and  a  discharge  of  mucus 
from  the  nostrils.  The  case  perhaps  is  regarded  as  a  common 
cold ;  suddenly  the  appetite  is  lost,  the  pulse  is  remarkably  quick 
and  weak,  and  the  membrane  of  the  nostrils  intensely  reddened. 
In  very  severe  cases  there  is  a  suppression  of  all  nasal  discharge, 
and  often  a  disappearance  of  the  cough.  In  fatal  cases  the 
symptoms  increase  in  intensity  for  several  days. 

There  is  a  total  loathing  of  all  food ;  the  nasal  membranes 
change  from  a  red  to  a  purple  hue;  the  extremities  are  cold; 
the  pulse  becomes  quicker,  weaker,  and  more  imperceptible;  the 
respiration  is  for  some  time  not  quickened,  but  deeper  than  na- 
tural ;  at  length  it  becomes  quicker,  and  the  horse  obstinately 
prefers  a  standing  posture. 

Thus  the  symptoms  continue  getting  gradually  more  aggra- 
vated, until  death  closes  the  scene  in  the  course  of  a  week,  more 
or  less. 

An  inspection  after  death  shows  the  mucous  membrane  of  the 
broncbiee  and  trachea.  Instead  of  being  white,  its  natural  colour, 
absolutely  purple  or  dark  green,  from  inflammation  and  gangrene. 

This,  however,  is  bronchitis  in  its  most  severe  and  dan'gerous 
form  ;  but  it  is  fortunately  not  so  frequent  as  when  it  assumes 
a  milder  appearance.  In  severe  cases,  there  is  often  a  consider- 
able discharge  from  the  nostrils,  and  a  distressing  cough ;  the 
pulse  is  quick,  from  50  to  70 ;  the  respiration  is  disturbed,  but 
not  much  quickened;  the  extremities  preserve  their  temperature; 
and  the  appetite,  though  considerably  diminished,  is  not  totally 
lost. 

This  form  of  bronchitis  is  more  frequent  than  the  former ;  and 
though  severe,  and  attended  with  danger,  is  yet  not  so  fatal  as 


124 


DISEASKS   or   THE    nOflSE. 


tlint  before  described.  In  the  latter  kind  ttie  inflummitory 
BCtion  in  grent  measure  expends  it^etf  in  the  increased  »ecn>tion 
of  mtictM ;  whilst  in  the  former  description  the  inletmitv  of  die 
infltimmniion  suppresses  all  secretion,  and  quickly  [ussea  on  to  a 
Riort-  miiligiiant  and  fatal  termination. 

nesi<teii  the  ti>'o  forms  of  bronchitis  jutl  described,  we  have 
often  a  milder  description,  termed  sub-acute,  in  n-hicli  Uic 
symptoms  of  tlie  latter  kind  arc  present,  but  altogether  in  a 
milder  form;  the  pulse  ia  less  frequent,  the  cough  lees  sev<-re,  th<! 
appetite  not  so  im])aired;  and  yet  these  symptoms  may  insidi- 
ously creep  on,  until  many  of  the  bronchial  tubes  and  air  cfWt 
an:  destixtyed  by  a  change  of  structure,  the  ca|>acity  of  the  luiign 
impaired,  and  the  animal  becomes  thick- u-inded. 

Thit  alteration  of  structure  may  result  fixxm  bronchitis*  eithrr 
in  it^  neuie  or  sub-acute  form. 
,      Occasionally  bronchitis  degenerates  into  what  is  called  aMrom'c 
'itaie;  tliat  i^,  the  inllammalion  lu-arlv  or  ^utte  ceases,  but  Ui<^ 
discharge  and  cough  continue,  particularly  the  former. 

Bronchitis  is  very  apt  to  be  mistaken  for  inHaminatioti  of  the 
lungs ;  atul  although  the  part  attacked  isaportion  of  iliese  organs, 
and  the  diseases  arc  oiten  present  at  the  same  time,  yel  the 
distinction  is  iinpoi-tant,  inasmuch  as  in  one  case  a  mucous  mem- 
brane is  diseased,  in  the  other  tlie  cellular  structure  of  the  lungs: 
tliL'  symptoms  of  these  aifections  nrc  not  oiilv  dilTi-renti  but 
tlie  treatment  too  requires  mod ificu lion.  Dronchitis  very  fre- 
quently assumes  the  form  of  an  epixoolic,  attacking  a  number 
of  hoi-se»  at  the  same  time.  When  this  is  the  case  the  discluuvc 
from  tiic  nodtiilit  is  exceedingly  profuse,  and  is  often  of  a  yw- 
lowifih  and  sonu'times  of  a  greenish  hue. 

Thi*  discn«;  is  generally  longer  running  its  course  than  pm'u- 
moniu;  and  when  its  progrei^i  is  unfavourable,  it  lerniinutci  in 
dcnlh  in  the  course  of  from  five  to  ten  days, 

^riie  'I'reatmeni  of  bronchitis  must  depend  on  the  form  which  it 
uiumes.  We  must  have  recourse  to  bleeding  in  tite  acute  diMiue, 
but  not  to  the  same  extent  as  in  pneumonia.  Fiom  thi-ev  to  five 
quarts  of  hlood  wilt  generally  he  a  sufficient  abstraction,  but  tiiii 
must  be  regulated  by  the  state  of  the  pulse  during  the  o{M>rution ; 
M  soon  as  it  Ciils  under  the  finger  the  bleeding  sliould  ceaac.  It 
it  sometimes,  tlioiigli  rarely,  requisite  to  bleed  again  lite  same 
day,  but  more  frequently  on  the  following  day;  and  sometimes 
three  or  four  venesections  are  n^uitx^,  whicli  of  course  muit  }ye 
n-gulaiiJ  by  the  symptoms.  'ITie  later  bloodlettings,  ln>wevi'r, 
miul  be  in  diminixhi-d  quantities.  When  bronchitis  asnuniet  aii 
4f>idcmic  form,  we  nnist  be  still  more  moderate  in  our  \'ene- 
scclions,  and  likewise  when  it  appears  in  a  sub-acute  state. 

The  Imwels  are  rery  frequenlly  in  a  costive  stale,  and  shouhl 
be  itnloaded  by  raking  and  injections;  but  the  greatest  caution 


CATABBai    COLD,    SORE    THROAT,    ETC  125 

must  be  observed  in  the  administration  of  aperients,  for  pur^n^ 
which  is  so  dangerous  in  pneumonia,  is  still  more  injurious  in 
bronchitis.  It  is  found  that  when  one  mucous  membrane  is  dis- 
eased, other  membranes  of  the  same  nature  are  from  sympathy 
in  a  very  irritable  state.  Thus,  though  it  is  desirable  in  this 
disease  to  unload  the  bowels,  it  is  injurious  to  do  ao  by  irritating 
their  internal  coats. 

We  may,  however,  venture  on  giving  from  one  to  two  drachms 
of  aloes,  or  five  drops  of  croton  oil ;  or,  what  is  still  better,  a  pint 
or  nearly  so  of  linseed  oil.  This  aperient,  however,  should  rarely 
be  repeated.  It  will  be  desirable  to  give  likewise,  in  the  form 
of  a  ball,  digitalis  half  a  drachm,  tartarized  antimony  one  drachm, 
nitre  tliree  drachms ;  to  be  repeated  twice  a  day. 

Mr.  Percivall  recommends  white  hellebore  instead  of  the  digi- 
talis, in  the  same  doses :  this  medicine,  however,  requires  cautious 
watching.  Extract  of  belladonna  is  also  employed  with  ad- 
vantage. 

Cotmter-irritation  is  of  great  importance  in  this  disease.  In 
the  course  of  six  or  twelve  hours  after  the  first  bleeding,  the 
course  of  the  windpipe  should  be  blistered  as  well  as  the  breast ; 
or  setons  should  be  inserted  in  the  course  of  the  windpipe,  and 
a  rowel  in  the  brisket.  Blisters  have  the  advantage  of  exciting 
a  quicker  action,  and  rowels  and  setons  a  more  lengthened 
eroct.  In  the  sub-acute  or  chronic  forms  of  the  disease,  the  tatter 
may  be  preferable,  but  in  the  more  severe  cases  the  speedier 
action  of  the  blister  b  demanded ;  and  it  is  often  desirable  to 
employ  both  methods  of  counter-irritation. 

The  proper  action  of  the  blister  or  the  seton  leads  us  to 
form  a  favourable  prognosis,  but  not  to  the  same  extent  as  in 
pneumonia ;  for  in  the  latter  disease  the  case  scarcely  ever  becomes 
httal  after  the  blisters  or  setons  have  produced  a  proper  effect, 
whilst  in  bronchitis  it  occasionally  does.  This  is  owing  to  the 
circumstance  that  in  pneumonia  the  circulation  is  more  languid 
on  the  surface  of  the  body,  and  the  blood  more  inwardly  deter- 
mined than  in  the  other  disease. — Ed.]

Hits  diecwe  has  been  termed  a  cold,  from  iHe  iuppo«ition  thai 
it  was  prodiic«-()  by  cold;  but  it  is  more  frequently  oceuiioncd  by 
tlie  alternation  from  cold  to  heal,  for  few  horses  vet  cold  from

during  the  prevalence  of  wet  weather. 

Ilii*  disease  freaiiently  apjicars  ns  an  epizootic,  when  the 
symptoms  are  usually  more  uigciit,  the  discharge  more  profutc, 
and  the  d«biliiy  greater.  In  this  form  it  is  wry  common

in  other  discnses,  as  in  influonm,  an  account  of  which  will  be 
separately  givi*n. 

The  duration  of  an  attack  of  catarrh  is  reiy  uitc<-rinin;  it 
may  lust  only  a  few  days,  or  as  niaiiy  weeks.  ThiK  in  mring

The  Termination  of  calarrh  may  be,  us  it  gcnemliy  is,

fever,  together  with  a  cough,  it  will  be  prudent  to  abstract  from 
5  to  10  lbs.  of  blood,  and  to  administer  from  2  to  3  drachms  of 
aloes,  so  as  tuildly  to  relax  the  bowels ;  and  to  follow  this  with 
the  following  ball,  given  several  days  successively  :  — 

Nitre 3  dr. 

Camphor   1  dr. 

Tartarized  Antimony    1  dr. 

Digitalis ^  dr. 

Made  into  a  ball  with  treacle. 

When  there  is  a  difficulty  in  swallowing,  or  a  cough,  it  will  be 
advisable  to  stimulate  the  throat  externally  by  rubbing  on  a  mild 
liquid  blister,  or  in  severe  cases  inserting  a  seton. 

When  there  is  a  considerable  discharge  from  the  nostrils,  it  is 
a  good  plan  to  steam  them,  by  suspending  a  nose>bag  containing 
bran  infused  in  boiling  water.  * 

When  the  inflammation  appears  to  be  extending  down  the 
windpipe,  it  is  necessary  to  apply  a  blister,  or  insert  setons  in  its 
course. 

The  diet  during  a  severe  catarrh  should  consist  principally  of 
mashes,  and  of  succulent  food,  such  as  carrots  in  the  winter, 
and  grass  in  the  summer. 

If  the  case  becomes  chronic,  the  nasal  gleet  continuing,  and 
the  animal  becoming  poor,  it  will  be  desirable  to  administer 
tonics,  such  as  the  following:  —

128  SI8EASFS    OF   THE   HORSE. 


Scarlatina. 


[This  disease  is  very  rare  in  the  horse,  there  being  but  a  few 
cases  on  record. 

Mr.  Percivall  treats  of  it  in  his  late  work,  and  thus  deBcriba 
its  nature,  symptoms,  and  treatment:  — 

"  Febrile  catarrh,  speedily  succeeded  by  the  appearance  of 
scarlet  spots  upon  the  Schneiderian  membrane  and  sortace  of  the 
skin,  attended  with  anasarca,  and  in  some  cases  dyspnoea. 

"  Symptoms. — For  two  or  three  days  at  tlie  commencement  it 
will  probably  be  mistaken  for  catarrh ;  about  this  time,  however, 
its  veritable  nature  becomes  manifested  by  the  appearance  of 
numerous  scarlet  spots  or  blotches  npon  the  membrane  lining 
the  nose,  possessing  the  hue  of  arterial  blood,  insular  in  sixe 
and  figure,  and  visible  as  high  up  as  the  membrane  can  bs 
inspected.  These  appearances  mostly  assume  the  character  ai 
petecblie,  though  I  have  seen  them  running  in  streaks.  Th^ 
look  like  so  many  patches  of  extravasated  blood;  but  if  one  of 
them  is  wounded,  blood  instantly  trickles  down  the  nose,  aad 
assures  us  that,  partially  and  singularly  distributed  as  it  is,  it  is 
still  fluid,  and  still  contained  within  its  vessels. 

"  In  passing  our  finger  over  the  red  spots,  nothing  like  pimple 
or  pustular  elevation  of  surface  is  discoverable.  The  skin  is 
every  where  similarly  bespotted ;  at  least,  I  inter  so  from  the  re- 
sults of  my  examination  of  the  body  of  one  horse  that  died  of  the 
disorder.  A  mucous  defluxion  proceeds  from  the  nose.  Aiw> 
sarca  is  a  common  attendant ;  the  1^^,  sheath,  and  belly  being 
on  occasions  considerably  tumefied.  The  respiration  is  quickene<^ 
hut  in  such  a  manner  as  rather  to  indicate  pain  than  embarrass 
ment.  The  pulse  is  likewise  accelerated,  and  beats  with  force. 
There  exists  great  disinclination  to  move  about.  The  appedte 
is  either  quite  lost,  or  very  much  impaired. 

"  Treatment. — In  two  cases,  early  venesection,  closely  followed 
up  by  the  exhibition  of  purgative  and  diuretic  medicine,  irith 
walking  exercise,  proved  completely  successful.  Another  case^ 
however,  had  a  fatal  termination :  it  was  not  altogether  in  my 
own  hands,  and  I  attributed  the  unfortunate  issue  in  some  mea- 
sure to  excess  of  walking  exercise,  practised  for  the  purpose  of 
keeping  down  the  anasarca  which  supervened  upon  the  primaiy 
attack.**— Ed.]

BTRAMOLES. 

CThis  disease  probably  derives  its  name  from  a  symptom  which 
is  occasionally  present,  in  wbtcli  the  animal  is  threatened  with 
Bufibcation. 

It  is  a  disorder  peculiar  to  young  liorsea,  and  attacks  them 
most  frequently  between  the  third  and  fifth  year,  though  not  un- 
(requently  before  this  period,  and  sometimes  after  it,  and  now 
and  then  we  even  meet  witb  it  in  old  horses. 

It  used  to  be  supposed  that  every  horse  becomes  affected  with 
it  at  some  period  of  his  life,  and  tbat  it  was  necessary  for  the 
constitution,  and  a  means  of  carrying  off  impurities.  From  the 
number  of  hands  into  which  horses  usually  pass,  it  is  difficult  to 
ascertain  whether  they  invariably  become  subject  to  this  disease 
or  not;  and  therefore  this  antiquated  assertion  is  rather  dif- 
ficult to  disprove.  My  own  opinion  is,  (hat  not  only  is  the 
complunt  not  invariable,  but  that  a  moiety  of  horses  altogether 
escape,  which  I  tfaink  will  be  borne  out  by  observation  amongst 
agricultural  boises,  that  are  both  bred  and  worked  on  the  same 
nrm. 

The  disease  sometimes  occurs  at  grass,  when  the  animal  is 
under  two  or  three  years  of  age,  and  sometimes  the  symptoms 
are  so  mild  that  no  treatment  is  required,  at  others  s(v  severe 
as  almost  to  threaten  suffocation ;  and  it  then  becomes  imperative 
to  take  up  the  colt,  and  have  recourse  to  the  most  judicious 
treatment. 

The  sympbmu  of  strangles  are  a  swelling  and  abscess  between 
the  lower  jaw  bones,  accompanied  frequently  by  sore  throat,  and 
other  catarrhal  symptoms.  There  is  often  a  considerable  degree 
of  fever  present,  together  with  an  indisposition  for  food,  as  well 
as  BD  inability  to  swallow  it;  liquids  being  swallowed  with  greater 
difficult  than  solids. 

The  swelling  upder  the  jaw,  slight  at  first,  gradually  in- 
creases, the  other  symptoms  increasing  in  severity  at  the  same 
time.  When  matter  has  formed,  it  usually  points,  as  it  is  termed, 
externally  ;  and  if  not  opened,  the  abscess  bursts,  and  the  symp- 
tcmiB  are  afterwards  much  relieved. 

Sometimes  an  abscess  hursts  internally,  and  the  matter  is  dis- 
charged through  the  nostrils.*  Occasionally  the  neighbourhood 
of  the  parotid  glands  is  affected,  and  the  swelling  is  so  consider- 
able as  to  threaten  suffocation,  and  demand  the  performance  of 
the  operation  of  trachaeotomy. 

Sometimes  the  enlargement  of  the  gland  becomes  hard  and

one  of  tartarized  antimony  may  be  given  (vrice  a  day,  in  a  mash. 
We  should  avoid  drencliing  as  much  as  passible,  in  consequence 
of  (be  soreness  of  the  throat.  A  slimnUiing  liniment  sliould  be 
nibbed  on  the  swelling,  and  a  wann  linstx-d  meal  poultice  applied, 
and  changed  twice  a  ilay. 

If  (hia  caiiiitit  lie  conveniently  done,  the  hair  should  be  cut  oiT 
and  the  part  blistered.  When  matter  can  be  readily  lelt,  a  large

CHAP.  XXVIII. 

CHRONIC    DISEASES    OF   THE    Altl-PABSAOES. 

Chronic  Cough. 

[We  have  spoken  of  cough  as  a  symptom  of  catarrh,  or  rather 
of  inflammation  of  the  larynx ;  and  although  we  have  now  to 
consider  it  under  a  distinct  designation,  it  is  yet  in  all  cases  a 
symptom  of  diseased  action,  radier  than  a  disease  itself. 

Tnere  are  various  descriptions  of  cough,  such  as  hard,  soft, 
dry,  short,  strong,  weak,  and  convulsive  cough.  These  nume- 
rous distinctions  will,  however,  answer  no  useful  purpose.  It 
will  be  sufficient  for  us  to  distinguish  the  aliort  dry  cougk  of 
broken  wind,  which  is  familiar  to  dl  practised  ears ;  the  dry,  or 
cough  leithout  disdiarge  ;  and  the  coi^h  attended  by  an  increased 
tecretian  ofmuau. 

Cough,  indeed,  denotes  the  presence  of  some  irritation,  and  is  in 
&ct  the  noise  made  by  the  forcible  endeavour  to  expel  this  cause 
of  irritation ;  for  instance,  in  catarrh  there  may  be  a  great 
increase  in  the  secretion  of  mucus,  so  much  so  that  if  not 
removed  it  will  threaten  suffocation.  The  entrance  to  the  wind- 
pipe is  lined  by  a  membrane  endowed  by  means  of  nerves  with 
the  most  delicate  aensibtlity.  The  presence  of  mucus  on  this 
part  produces  irritation.  The  sensation  is  instantaneously  sent 
to  the  brain,  and  thence,  by  means  of  the  nerves  of  motion,  an 
impression  is  conveyed  to  the  diaphragm  and  abdominal  muscles, 
by  which  these  parts  are  thrown  into  violent  action ;  air  is  rapidly 
expelled  Irom  tne  lungs  through  the  windpipe,  carrying  with  it 
most  probably  the  offending  object ;  and  thus  a  cough  is  produced. 
The  same  effect  is  occasioned  when  any  foreign  body  enters  or 
endeavours  to  enter  the  larynx,  and  likewise  from  simple  irri- 
tation of  the  part  without  any  increased  secretion  of  mucus,  as 
well  as  from  too  great  dryness  of  the  jpart,  and  probably  also  from 
sympathy  with  another  part.  Cough  is,  indeed,  but  an  effort  of 
nature  to  ward  off  mischief,  and  in  endeavouring  to  cure  it  we 
should  strive  to  remove  the  cause  by  which  it  is  produced.  Too 
much  regard  should  not  be  paid  to  the  sort  of  cough  that  may 
be  present ;  for  we  may  have  in  catarrh,  and  even  in  the  same

Broken  Wind. 

HHorses  vith  broken  wind  are  usually  called  pipert  by  horse 
dealers. 

The  symptoms  of  a  badly  broken-winded  horse  are  readily 
perceptible;  the  peculiar  catching  of  the  flanks  is  seen  by  the 
common  observer.  There  is  in  fact  a  double  expiration  to  a 
single  inspiration ;  the  horse  readily  draws  in  liis  brtath,  but  has 
a  difficulty  in  forcing  it  out,  and  the  abdominal  muscles  are  called 
on  to  assist  the  operation  in  a  much  greater  degree  than  in  a 
state  of  health. 

The  respiration  is  also  quicker  than  natural,  and  there  is  ge- 
nerally  a  peculiar  short  cough.  This  cough  in  mild  cases  may 
be  slight,  but  in  bad  cases  it  is  extremely  distressing,  continuing 
perh^ts  almost  incessantly  for  half  an  hour  together. 

The  symptoms  may  rapidly  get  worse,  until  a  horse  is  un- 
fitted for  any  thing  but  slow  work ;  or  they  may  continue  in  the 
same  state  for  years,  during  which  the  animal  is  capable  of  doing 
a  good  deal  of  work. 

It  is  very  common  for  the  symptoms  in  draught  horses  to  ap- 
pear suddenly,  particularly  if  the  animal  is  worked  severely  on  a 
full  stomach. 

We  find  this  affection  more  frequently  in  cart  horses  than  in 
any  othen. 

On  the  dissection  of  broken-winded  liorses,  we  notice  the 
lungs  to  be  considerably  larger  than  in  a  healthy  state,  and  much 
whiter  on  the  surface.  On  cutting  into  them,  we  6nd  that  their 
increased  volume  is  owing  to  air  extravasated  under  the  mem- 
brane  which  covers  them.  The  air  cells  are  supposed  to  have 
been  ruptured,  so  as  to  have  admitted  the  escape  of  the  inspired 
air,  which  is  thus  easily  drawn  into  the  lungs,  but  has  much 
greater  difficulty  in  escaping. 

The  membrane  lining  the  bronchial  passages  is  also  generally 
Ibund  in  an  unnatural  state,  being  much  thicker  than  in  a  state 
of  health,  and  this  circumstance  is  considered  to  account  for  the 
cough  that  attends  the  disease. 

The  symptoms  of  broken  wind  have  l>een  suddenly  manifested 
by  some  horses,  and  on  dying  soon  afterwards,  it  has  appeared 
that  the'  diaphragm  has  been  ruptured.  Any  thing,  therefore, 
that  will  materially  embarrass  the  action  of  this  muscle  is  likely 
to  occasion  these  symptoms. 

Broken-winded  horses  rarely  carry  much  flesh,  which  is  owing 
to  the  disordered  state  of  the  stomach  and  bowels ;  a  greater 
quantity  of  wind  is  formed  in  the  bowels  than  common,  which  is 
frequMitly  expelled  from  the  anua.     There  is  no  way  of  account-

ing  fur  this  disordered  *tatc  of  the  digestive  orgatis,  except  from 
llip  Hympatli;. 

TliK  iiittnediate  eaiue  of  broken  wind  is  obviously  the  circum- 
Btance  of  sudden  exertion  on  a  full  atonmch.  In  proponion  In 
the  indifjcsiible  nalure  uf  food  is  the  dtaease  likely  to  occur. 
Thus,  fusty  and  damaged  hay  is  a  very  frequent  cause ;  and  lHu 
hay  being  frequently  given  to  agrietiltural  horses,  accounts  in 
crent  men«ure  for  the  disean-  being  more  frequent  with  then 
than  with  any  others.  Nimrod,  the  celebrated  »i>oniiig  wnier, 
say*  the  di»e«»c  is  extremely  rare  in  France,  «herc  he  now 
reside*;  and  this  he  attributes  to  the  fact  of  wvel  sirnw  tx-iiig 
gtMierally  used  instead  of  hay,  particularly  amongst  lurm< 
horsey. 

Tmifmmt,  —  Although  a  perfect  cure  for  lliw  di«easr  mnnol 
be  attained,  yet  we  can  do  very  much  lowanls  nlirviniing  ir,  and 
rendering  the  iiniuvd  useful.  Nothing,  iiidei-d,  i.i  more  i-onimon 
than  for  broken.winded  lioi-sn-s  to  get  cun»id(-rabiy  heiu-r  after 
being  worked  for  some  lime  in  a  coach.  Thi*  improvement  is 
owing  to  the  alteration  in  their  diet:  instead  of  hay  forming  the 
principal  part  of  the  food,  it  is  given  only  in  small  quantities,  but 
m  its  place  plenty  of  sweet  com  is  allowed.  Tliis  then,  is  the 
plan  to  he  adopted ;  viz.  to  give  the  greatest  quantity  of  nourisli- 
nient  in  the  smallest  hulk,  by  which  two  objects  are  aceonipliiihi'd: 
the  condition  and  strength  of  the  animal  arc  improved,  and  he  in 
capable  of  making  greater  exertion  with  the  same  amount  of 
breathing  as  before;  and,  in  the  second  place,  (he  stomach  never 
being  so  distended  as  before,  no  longer  presses  so  mueh  against 
the  dinphriijtn),  and  respiration  is  thus  rendered  less  difficult. 

Little  or  no  Imy  shotiM  therefore  be  allowed,  except  in  the  form 
of  chaR':  but  in  the  winter  carrots  may  he  given,  and  in  t)ic  sum- 
mer vetches;  but  holh  in  moderate  quantities. 

The  digeJiive  organ*  should  be  kept  in  as  healthy  a  state  as 
postible,  and  cure  should  be  taken  lliai  the  horse  is  fed  some 
liours  before  he  is  worked.—  Kn.] 

I  have  several  times  so  far  sueceeiled  ns  to  cure  the  disease  fur 
a  time;  and  in  one  case,  a  horse  of  my  own,  the  disi«.<)i-  was  so 
completely  reinove<J,  tliat  I  kept  the  animal  in  constant  work  for 
more  than  a  year  afterwards. 

This  horse  was  as  hadly  broken  winded  as  a  horse  could  be> 
He  was  kept  on  bran  and  oats  and  a  moderate  quantity  of  good 
hay.  In  (he  s]>ring  lie  had  some  velches  and  grass  in  ilw  stable, 
which  was  c\>ol.  and  well  ventilated.  lie  was  ridden  at  first  very 
moderately ;  but  after  two  or  three  months  he  was  ridden  aia  full 
trot,  and  somclimes  galloped  without  inconvenience.  I  hare 
seen  another  case  of  complete  broken  wind  apparently  cured  by 
turning  the  animal,  in  dry  summer  weather,  into  a  field  where 
there  was  no  water.     This  mare  had  been  purchased  as  a  subject

for  some  rxpcrimeiiU  rdaitrc  to  glanders,  being  so  bad  as  (o 
be  tlmuKht  fit  for  iiollitng  e\se.  After  the  experiments  were 
itnistutl  I  thought  it  right  to  kill  Ikt,  when  I  found  the  lungs, 
kihI  all  t)>c  parts  coniiecKrd  with  them,  perfectly  sounil,  and  at 
the  time  »!»(.•  wa»  killed  not  n  nymplom  of  broken  wind  could  bo

a  similar  manner,  nrid  with  tbir  Mtme  rc«ult ;  and  I  have  eciii

A  diort  time,  but  gel  at  bad  lu  ever  n  liiue  time  after  they  had

If  the  cough  be  iroubleaome,  the  ball  advised  for  chronic 
eough  may  be  administered  occasionally.

[Tliii  disease  is  very  diflTcrent  from  broken  wind,  ahhougli  ihey 
arc  oftiii  confoinidi-^I  log<'ther.  It  is  chariicteriseil,  not  by  a 
double,  but  a  quickened  respiration,  it  Iwinjj  f«'(jiieiitly  treble 
or  mi»dni]>ie  its  natural  »Uiie,  It  is,  indeed,  more  Kenous  than 
brolceii  win<l,  inatnmch  iix  it  has  tisually  been  preceded  by  an 
infLinimatory  attack,  which  may  again  recur. 

'Die  lungs  of  thick-winded  horses  have  their  cApacily  for  air 
diminislM.'d — the  structure  of  the  lungs  is  clumged — a  piirt  be- 
comes heavy,  indurated— tiie  air  cells  and  brnnchial  passages 
become  filled  up,  so  that  the  lungs  no  longer  ailord  the  same  room 
for  tlte  reception  of  the  aimoripiierii:  air.  and,  in  consequence,  the 
liorse  is  obUged  to  breathe  double  or  treble  as  quick  as  in  a  slate 
of  health. 

This  disease  is  usually  the  effect  of  aii  inftammatioit  of  the 
lungs;  but  sometimes  thick  wind  comes  on  without  tuiy  aoiitc 
inflammatory  attack.  In  «uch  cnse<<  there  has  usuiilly  been 
chronic  bronchitis  which  luw  probably  been  mltlaken  for  a  cold, 
and  has  not  left  the  horse  until  it  has  sadly  altered  the  structure 
of  lite  lungs. 

Tli«  symptoms  of  thick  wind  are  more  obscure  lliaii  those  of 
broken  wind ;  as  the  qiiiekneKs  of  respiration  after  exercise  is  so 
much  ulfc^ied  by  the  condition  of  t)ic  animal,  a  horse  weak  and 
out  of  wn«iilion  will  often,  under  severe  exertion,  breathe  quicker 
tlian  a  thick-winded  horse  in  good  condition.  This  fact  must  be 
borne  in  mind  and  allowed  for,  when  passing  an  opinion  oa 
iIm-  cnse. 

It  is  astonishing  what  great  alteration  of  the  structure  of  tbc 
lun;^  may  exist,  and  the  horse  be  still  able  to  perform  his  aeeus- 
lumed  work.  I  remember  a  horse  that  for  some  months  woiketl 
in  •  fast  coach,  doing  a  sltt^e  of  twelve  rnilc^  daily  in  about  one 
hour  and  a  quarter.  He  wai<  Sei/ed  with  iiiflamnialion  of  the 
lungs,  anddied  in  thecourseof  sixteen  hours.   On  examining  the

ROAR I NO. 


[This  ditteaAe  receives  its  denomination  from  tlie  nature  of  tbe 
noiite  made  by  tbe  horte  ofiected  nlieii  hie  i-esni ration  is  quick- 
ened by  exercise.  It  arises  in  &ct  from  a  diminution  of  llic 
calibre  of  the  windpipe,  or  ihc  larynx,  or  Eomc  portion  of  the 
air  fKUagcK  Therr  arc  various  names  used  in  liorec  phrase-

as  ^"""'■'''t  wlii"lifr,  wlici-WT,  higbblowcr,  iruiiiiKHiT,  &c.  'the 
tint  denotes  Uit?  iwim-  made  by  a  roarer  when  xtiddenly  fright- 
ened. All  roarer*  do  nut  nmke  tliis  noise,  but  wlien  it  is  proent 
the  roarinj;  is  generally  severe  and  confumetl. 

A  lehiitier  is  a  very  bud  roarer,  inasmucli  as  tlie  shrill  noise  of 
witistlin)!  is  a  %\^n  of  there  beinj^  a  smaller  passage  tlian  wbcn 
the  |;(raver  sound  uf  r(Minn<f  U  heard.  This  was  pni  tu  ilie  proof 
by  Mr,  IVrcivall,  who  tit^l  a  ligaitire  round  the  nindpipe  of  n 
hoi-se  moderately  tight,  and  then,  trotting  the  animal,  foaixl 
that  tio  roared;  but  on  drawing  the  ligaiurc  tighter,  so  as  to  lessen 
the  calibre  of  the  windpipe  one  half,  a  whistling  noise  was  heard. 

A  wlieaer  makes  a  noise  somewhat  like  its  di?»ignAlton,  bruig 
lest  loud  than  that  nf  roaring.  It  arises  of  course  from  ob- 
structed rt^iratioM,  either  in  the  larynx  or  windpipes  or  the 
bronchial  passages ;  such  obitruction,  however,  tiol  beiugto  great 
as  in  roaring. 

Wheezing  is  frequently  present  in  thick  wind,  and  indeed  is 
generally  owing  to  olt^tructinn  in  the  lungit  tlH-mselves. 

A  Irumpeler  is  merely  a  fancied  diniinL-tion ;  but  a  highMimtr 
it  usually  no  roarer  at  all,  the  noise  he  niakeii  being  a  sort  of 
snort,  arising  from  the  peculiar  action  of  the  false  nostrils  which 
many  horses  possess.  'I'his  sound  is  frequently  mistaken  for 
roaring,  but  may  be  readily  distinguished  by  galloping  the  bones 
when  it  will  be  found  ihat  the  noise  is  grraiest  at  lirsi,  lessens  at 
he  proei^edx,  and  goes  olT  as  the  speed  increases;  an  effect  prv 
cisely  cuiiliury  to  that  attending  roaring.  A  case  of  this  kind 
lately  CHine  under  my  notic',  in  which  the  noise  made  by  the 


ROARINO.  137 

horse  somewlint  resembled  a  steam  eufii;ine  at  work,  so  coiivldfr- 
able  was  iL  litis  noise  commenceil  immediatc^l^'  tlie  horse  mm 
excited;  but  after  several  trials  1  found,  by  causing  tlie  hoi'u-  tn 
gallop  wiifaoui  exciting  him,  tio  noise  was  produced.  Various 
jiartics  learned  in  horse  matters  pronounced  him  a  roareri  but  I 
gave  a  contrary  opinion;  the  truili  of  which  was  proved  by  his 
carrying;  n  lieavy  weight  in  capital  style  through  the  following 
season,  the  noi»o  going  off  as  the  pace  improved.  It  is,  1  think, 
wry  probable  that  the  case  of  the  celebrated  Eclipse  was  one  of 
this  description. 

The  noiie  of  roaring,  and  iu  modification*,  is  produced  by 
various  diieaiied  structure*  which  morbid  anatomy  lia«  brought 
to  light.  Thickening  of  the  mi'mbrune  uf  the  larynx  is  a 
very  frequent  cause  of  roaring,  and  is  generally  produeed  by 
eore  throat  or  bronchitis.  Sometimes  bunds  are  thrown  across 
tlie  windpipe,  which  is  the  effect  likewise  of  inflammation.  It  is 
impossible  to  ascertain  when  they  exist,  or  where,  otherwise 
it  would  be  no  difGcutt  task  (o  open  the  windpipe  and  divide 
them.  This  was  once  done  with  success,  but  attempted  linndreds 
of  timcv  and  fiiik-d.  Ossification  of  the  cartilages  of  the  larynx 
u  another  cause  of  roaring,  and  is  produced  by  previous  inHam- 
mation.  Ulceration  of  the  membrane  of  the  glottis  is  likewise 
another  cause  of  roaring;  and  It  is  supposed  by  Mr.  Field  that 
when  this  is  the  ease,  the  Irritation  experienced  in  breothing 
induces  the  animal  to  partially  shut  the  glottis,  and  thus  occasion 
ifae  noUe  of  roaring. —  El).] 

I  found  two  cmo-t  of  vcn,'  b;id  roaring  occasioned  by  ulceration 
within  tlw  larynx ;  in  one  of  them  the  ulcer  was  very  small,  and 
close  to  the  chink.  One  of  these  horses  had  been  aHected  for 
Boine  time  with  the  mild  or  chronic  glanders,  and  belonged  lo 
Mr.  Ruasel's  glandered  team.  He  was  in  good  condition,  and 
breathed  freely  until  put  into  motion.  It  rendered  him,  how- 
ever, so  useleis  that  he  was  destroyed.  The  other  horse  was 
attacked  in  the  stable  with  violent  eooghing,  and  soon  after  with 
roaring,  probably  from  an  oat  or  sonte  of  his  food  getting  into 
■he  larynx.  He  was  turned  to  grass,  and  soon  became  so  dis- 
tressed, his  breathing  being  heard  at  a  considerable  distance, 
that  it  was  thought  right  to  destroy  him.  llie  only  morbid 
appearance,  found  upon  a  careful  examination,  wok  a  Kuudl  ulcer 
on  one  side  of  the  chink  of  the  glottis. 

[R(xu-ing  is  frequent  with  carriage  horses,  in  whom  it  is  gene- 
rally profhiced  by  light  reining,  so  as  to  make  the  neck  more 
arclu-<l ;  by  this  unnatural  position  the  wimlpipe  is  distorted  so  as 
to  cause  un  impediment  lo  respiriiiion,  and  thus  produce  roaring. 
In  some  can-*,  alihougli  they  nre  not  nunierou*,  the  cause  of  roar- 
ing luis  iipjHfintI  to  lie  in  the  lungs;  but  when  this  is  the  case 
thick  wind  is  also  pn-Hcnt.

Mr.  James  Turner  has  found  that  roaring  has  been  produc 
by  ttnlariteineiit  of  ihe  turbinated  bones  of  the  noslrik,  but  we 
ima^jine  it  is  not  a  frenuent  cause.

dispute  whether  in  these  caset  litis  appearance  of  ttie  inu»cle« 
is  a  cause  or  a  consequence  of  roaring.  Some  contend  tliut  the 
roaring  arises  from  an  aflecliou  of  the  nervet,  before  alluded  txt, 
by  which  the  muscles  are  thrown  out  of  action)  and  theretbre 
become  al^orbed.     To  this  opinion  1  am  disposed  to  incline. 

Such  are  the  various  diseases  which  prodtice  roai'in;;  in  the

pipe,  polypi  in  the  nostrils,  and  indeed  any  thing  either  tempo-

It  U  iin  object  of  much  importance  to  bring  iJie  horse  to  the 
liigheM  possible  condition,  so  tliai  bis  wind  shall  be  in  a  good 
state,  as  lie  will  then  be  much  less  likely  to  roar  than  if  out  of 
condition.  For  the  same  reason  the  rules  recommended  for 
broken  wind  should  also  be  oh»ervcd  in  roaring:  for  ahhouvh 
the  wind  is  not  usually  impaired,  yet  the  noise  will  be  great  m 
proportion  to  the  demand  made  on  the  lungs.  Thus  wc  often 
lind  that  a  ihoroiigh-brcd  horM.-  will  roar  in  raeinjj,  but  not  in 
hunting!  a  hunter  will  do  so  in  huntin-^,  but  not  in  liamen; 
K  harnt^M  liumo  may  roar  in  fast  work,  and  not  in  slow ;  and  y«t 
nil  tlxHe  liones  mny  linve  tlie  defect  in  the  same  degree,  tlie 
liifTiTenoe  arising  iVom  their  different  capaeities. 

Uouring  is  decidedlv  hereditary,  at  least  the  disposition  to 
become  to  is,  for  the  oflsprins;  of  roarers  have  in  a  gn-at  nuniber 
of  inelances  become  roarers  tnemsekes. 

When  tile  roaring  is  so  se^'erc  as  to  r«nder  the  horse  quite 
useless  the  operation  of  tracheotomy  is  to  l>e  recommended,  a 
tube  made  for  the  purpose  being  kq)i  in  t)>c  opening  made  in 
the  windpijie,  out  of  wliicli  the  horse  will  brnithe.  Ily  taking 
gn-iit  care  that  the  tube  remuitis  in  its  place,  the  animal  may  be 
able  to  do  moderate  work. —  En.] 

I  once  saved  a  horse's  life  that  appeared  to  have  an  oat  or 
some  of  hit  food  in  the  larynx,  by  the  operation  named  bron- 
chvtomy.  I  found  ihe  lionte  in  the  most  distressing  sitoation. 
He  was  scarcely  able  to  breathe,  and  \i\*  hrcathinz  wm  >o  loud 
as  to  t)e  heard  at  a  distance  of  many  yartln ;  and  there  was  a 
discharge  of  bloody  mucus  from  the  nostril.  Attenipi*  had  been 
made  to  wash  down  what  appeared  to  be  slicking  in  his  throat, 
and  to  force  it  down  wiih  a  prohang.  I  made  aji  opening  in  the 
front  of  the  windpipe  about  6  incliea  Iwlow  tlie  throat,  and  llien 
thrust  a  probang  upwards  through  the  larynx,  and  immediatelv 
withdrew  It  again.  The  horse  was  relieved,  and  got  quite  well- 
He  woi'ked  as  a  post-horse  for  scvei'al  yearsal\er,  and  was  named 
by  the  post-hoys  Ciil-throat. 

[If  tlw?  roaring  ts  recent,  and  produced  by  tight  reining,  we  may 
eJTvci  considerable  benelit  by  leaving  off  the  bearing  rem,  nnd 
elevating  the  head  and  muzilc  for  some  hours  daily  in  the  stable, 
in  a  contrary  position  to  that  produced  by  light  reining. — Eo.] 


DISEASES   OF   THE    DIAPHRAOM    AND    THE    HEART.  141 

CHAP.  XXX. 

DISEASES   or   THE    DIAFHRAOM    AND   THE    HEART. 

[The  diaphragm  or  muscle  which  separates  the  chest  from  the 
abdomen  is  liable  to  two  diseases,  spasm  and  rupture. 

Spasm  of  the  diaphragm,  of  which  there  are  several  cases  on 
record,  is  denoted  hy  a  Toud  thumping,  sometimee  perceptible 
Bereral  yards  off,  and  felt  at  various  parts  of  the  body,  but  parti- 
cularly at  the  region  of  the  diaphragm ;  the  heart,  at  the  same 
time,  being,  though  quick,  yet  very  weak  in  its  action,  and  the 
pulse  at  the  jaws  almost  imperceptible.  The  respiration  is  usually 
quick  and  laborious,  and  ia  sometimes  attended  by  shivering. 

The  cause  of  these  symptoms  is  over-exertion,  particularly 
on  a  full  stomach. 

The  treatmmi  which  is  generally  successful  consists  of  bleed- 
iog,  followed  by  aperient  medicine,  and  opiates. 

Rupture  of  the  diaphragm  is  to  be  attributed  to  the  same 
causes  as  the  forgoing  disease,  —  any  thing,  indeed,  which  aud- 
deoly  demands  a  powerful  respiration;  and  in  several  instances 
it  has  been  known  to  occur  to  oroken-winded  horses. 

The  exertions  used  in  parturition  have  sometimes  ruptured 
the  diaphragm,  and  so  likewise  have  the  struggles  of  colic. 

This  disease,  although  always  attended  eventually  with  a  fatal 
termination,  has  yet  been  known  to  exhibit  for  some  time  the 
symptoms  of  broken  wind.  In  such  cases  the  diaphragm  has 
been  only  moderately  ruptured,  and  a  portion  of  the  intestine 
insinuated  through  the  fissure.  —  Ed.] 

Diseases  of  the  Heart. 

[Amongst  all  the  diseases  to  which  the  horse  is  liable,  there 
are  none  more  obscure  in  their  symptoms,  or  more  fatal  in  their 
terminations,  than  affections  of  the  heart. 

They  rarely,  however,  occur,  but  as  connected  with  other  dis- 
eases, the  obscurity  and  danger  of  which  they  greatly  increase. 

Dropsy  of  the  heart,  or  water  in  the  pericardium,  often  ac- 
companies hydrothorax,  and  sometimes  occurs  in  inflammation 
of  the  lungs  and  pleura ;  the  water  being  occasionally  so  great  in 
quantity  as  absolutely  to  choke  the  action  of  the  heart.  We 
sometimes  find  lymph  floating  in  the  water,  or  streaks  of  lymph 
adhering  to  the  pericardium. 

This  disease  often  accompanies  enlargement  of  the  heart  itself, 
which  sometimes  weighs  double  what  it  ought  to  weigh.

The  lieart  is  sometimes  Ibund  not  only  gn-atly  incrctuvd  in 
size,  but  quite  altered  in  its  appearance,  presenting  an  irregular 
Tungoufi  inas«.  In  a  ease  ol*  this  sort  tttai  I  met  vriili  a  few  ypars 
since,  the  birnting  of  the  heart  was  particularly  lottd,  hollow,  and 
tliuinpliig,  though  not  greatly  tncrcftM-tl  in  number.  The  seat 
of  disease  was  iwintcd  ant  by  the  apparently  laborious  actwa  of 
the  hearL 

"  Mr.  Pritchard,  who  luu  communicated  several  interesting 
cases  of  disease  of  the  heart,  observes,  in  the  6th  vol,  of  ilw 
I'eteriMnr'uw,  on  (he  subjett  of  hvpertrophv,  or  cnlargeateni  of 
the  heart:  —  "It  lia*  always  struck  me  forcibly  that  over-exertion 
is  tile  principal  exciting  ciiiiBi-  of  hypertrophy,  and  of  dilnUilion ; 
and  I  may  add,  the  possibility  that  the  original  structure  of  the 
heart  may,  in  some  subjects,  be  tinvtiual  in  power  to  tlie  olEoe 
it  is  d«.-signed  to  perform. 

'*  This  opinion  is  strongly  tupported.  Horses,  particularly 
those  empluved  in  quick  draught,  arc  commonly  called  on  to 
perform  arduous  tasks  with  full  s^tomachs,  by  which  tJic  free 
action  of  the  lungs  is  considerably  impeded;  thus,  obstruction 
being  given  lo  ihc  circulation  through  the  pulmonary'  vessels, 
eorre»poniiing  increase  of  force  in  the  action  of  llic  Itcsrt  u  Ow 
const'ijuenct-. 

"  The  first  inconvenience  felt  by  the  animal  durinff  exertion  is 
in  tlie  respiratory  organs,  and  this  more  i-»|)eciiilly  wnen  the  »i»- 
mjich  \n  distended,  as  tlien  iho  cavity  of  the  chest  i*  dimini*lK'd : 
tlic  lungs  are  not  inflated  with  ease  to  the  extent  rwiuirt<l  for 
the  blood  to  flow  uninlcnuptedly  through  iheui, 

"  Hypertrophy  of  the  right  tide  of  the  heari  is  liable  10  be  con- 
founded with  pneumonia,  as  tlie  lunga  are  readily  oiTecied  in  lliit 
case  ;  but  there  is  ihisobvious  difference, — the  breathing,  althougli 
qaickcnod  and  laborious,  is  less  frequent  than  in  pneumonia; 
the  piilxe,  notwithtinnding  it  is  quick  and  intermittent,  is  not  *n 
much  opprc'^Ked ;  the  sub-maxiliary  artery  is  more  dilated,  lite 
flow  of  blood  through  (he  jugular  is  more  current;  the  ni«m> 
branes  of  the  eye  anil  nostnln  an.-  less  injected ;  tlic  surface  of  llie 
body  and  extremities  ia  of  a  moderate  warmth,  aiKl  these  lut 
symptoms  are  present  when  the  respiration  is  exceedingly 
diflicuU  and  laborious.  Copious  bleeding  does  not  cause  inut 
clwihge  in  the  character  of  the  pulse,  nor  afford  comparative 
relief  to  the  rvspirstion." 

There  arc  one  or  two  cases  on  record  of  ossification  of  the 
substance  of  the  heart.  OMificaiion  of  the  vulve«  is  still  more 
fivfiuent,  though   by  no  means  so  common  as   in  the  huRuin 


DISEASES    or   THE    STOMACH    AMD    BOWELS.  143 

Carditis,  or  iDflammation  oF  the  hearl,  is  exceedingly  rare  in 
the  horse,  and  is  always  connected  with  other  disease. 

The  heart,  in  a  few  instances,  has  been  ruptured ;  in  one  case 
from  severe  exertion,  and  in  another  from  previous  ulceration. 

ADeurism  of  the  aorta  and  other  arteries  has  been  discovered 
in  the  borse,  but  is  by  no  means  so  frequent  as  in  the  human 
subject. 

Little  can  be  stated  by  the  way  of  treatment  for  the  foregoing 
diseases.  They  have  K^nerally  existed  some  time  previous  to 
tlie  requisition  for  medical  assistance,  and  there  is  generally  an 
inability  for  bearing  extensive  bloodletting.  The  treatment, 
however,  must  be  altogether  adapted  to  the  symptoms  that  may 
present  themselves,  and  r^ulated  by  the  principles  before  men- 
tioned.— Ed.]

DISEASES    OF  THE    STOUACH    AND    BOWELS. 

Inflammation  of  the  Stomach,  Gastritis. 

AcDTE  inflammatiou  seldom  takes  place  in  the  stomach  but  from 
swallowing  poisons,  or  some  powerful  stimulant,  at  a  time  when 
this  important  organ  is  already  in  a  morbid  or  irritable  state- 
Mr.  James  Clarke  relates  a  case  where  a  horse  was  destroyed  by 
inflammation  of  the  stomach,  in  consequence  of  being  drenched 
with  a  pint  of  vinegar;  and  another  in  which  the  same  fatal* 
effect  was  produced  by  a  drench  which  contained  half  an  ounce 
of  spirit  of  hartshorn.  It  is  probable  that  neither  of  these 
drenches  would  Iiave  had  any  injurious  effect  had  the  stomach 
been  in  a  healthy  state.  I  have  known  a  horse  quickly  destroyed 
by  being  drenched  with  a  quart  of  beer  in  which  one  or  two 
ounces  of  tobacco  had  been  infused,  and  have  seen  other  horses 
take  much  larger  doses  without  any  ill  effect.  I  have  also  known 
a  drench  which  contained  two  ounces  of  ether  destroy  a  horse  by 
inflaming  his  stomach ;  and  in  one  instance  four  ounces  of  oil  of 
turpentine  produced  a  similar  effect,  but  this  horse  was  under 
tbe  effect  of  a  moderate  purgative  at  the  time  the  turpentine  was 

S'ven.  Whenever  a  medicine  produces  an  injurious  effect  upon 
e  stomach,  I  think  it  is  generally  indicated  by  the  shivenng, 
•baking,  or  trembling  which  immediately  follows.  I  have  seen 
a  strong  infusion  of  tobacco  produce  this  effect;  also  a  solution 
of  arsenic.  I  gave  several  doses  of  arsenical  solution  to  a  glan- 
dered  horse,  and  it  was. Invariably  followed  by  shivering;  it 
was  a  large  dose,  from  two  to  four  ounces  of  Fowler's  solution. 


DtSEASBR   OF  THE    nOBsr. 


Tlic  shivering  went  oflT  in  Bbout  an  )»our.  At  first  I  gsve  the 
liorse  a  litilo  warm  beer,  n-iih  some  ginj^r  in  it,  lo  stop  the 
fihivpring,  but  Rflcrwarcls  I  suifpred  it  lo  go  offof  iuown  aceoni. 
It  IB  worthy  of  remark,  that  altltotigh  this  horse  did  not  apjKvr

«ome  other  morbid  state,  is  bv  no  means  an  iiiirr^i|iient  oc- 
ciirren<%.  I  am  inclined  to  thinlc  that  holts  disonter  t))c  slomacli 
in  this  way  more  freouently  than  is  generally  siupecitx).  The 
symptoms  of  acute  innammation  of  the  stomach  are,  a  vf  ry  quick 
and  weak  ptilsc,  great  depression  of  spirits,  quick  breathing,  nod 
coldness  of  tliv  ears  an<)  legs.  I  have  seen  all  these  aymptotiu 
brought  on  by  giving  four  ounces  of  nitre  at  oik-  dose.  I  Imvc 
seen  It  produced  alxo  by  Urge  dotoa  of  subliinnk-,  arsenic,  and 
1)1  no  vitriol.

fatal  case  that  occurred  to  the  editor  a  few  years  sinci*,  the  symgv 
loms  presented  were,  an  exceedingly  dull  and  stupiRed  appear- 
ance— eyes  siidueed  with  tears — eyelids  swollen,  and  nearly 
closed  —  mouth  hot  —  farces  hard,  and  coated  with  tnucus — a,b- 
dometi  enlarged — pulse  65,  and  oppressed.  The  mare  luul  been 
.  ill  several  days  hetorc  I  saw  her.  On  the  second  day  the  doll 
and  heavy  appearance  was  entirely  gone,  bul  the  pulse  66. 
The  third  day  the  mare  appeared  in  the  same  dull  state  as  on 
the  6m  day,  the  iHilsc  60.  On  l\w  fourth  day  »be  appeared 
worse,  the  pulse  il4 ;  but  the  heavy  appearance  of  the  head  )»d 
again  diKnppeared.  The  mare  died  during  the  night;  and  oil 
examining  ber  the  stomach  was  found  excessively  inflajned,  and 
a  thick  deposit  of  coagiilaied  blood  between  its  coats,  aiTectiog 
more  particularly  the  ciilicular  portioD.  The  bowels  were  in- 
flamed in  a  minor  decree,  as  well  as  the  lungs  and  liver.  TIk 
mare  had  been  taken  from  grass  and  fed  with  dry  and  stimulttiii),' 
food,  without  any  phytic  or  other  p  repaint  ion.

IjOU  of  Appetite. 

Want  of  appetite  b  more  frequently  complained  of  in  horacs 
than  an  excessive  or  ctavint;  iii>|H'liic;  this,  indeed,  so  far  from 
bving  comntaincd  ol",  U  jfi-neniliy  coiwidercd  a  desirable  (jnalifi- 
calton  in  tlio  animal ;  but,  as  I  have  before  observed,  more  dia. 
Tfl£e«  arisv  from  this  caioe  than  from  want  of  appotite.  A 
distinction,  Iwwever,  mii«  be  made,  between  im  excessive  or 
Toracioiu  appetite,  and  a  hcAity  and  healthy  appetite.  The  hit- 
ler is  denoted  by  the  horM.-  being  ready  for,  or  desirous  of  food, 
as  soon  as  he  conies  in  from  a  journey,  and  eatins  his  alluwaivce 
witli  an  evident  relish.  The  former,  by  an  almosl  constant 
craving  ior  food  and  waier,  without  any  regard  to  the  quality  of 
cither.  lu  weakness  of  appetite,  a  horse  is  rattu>r  indillerent 
ftboiil  food  when  be  comes  in  from  a  journey,  and  will  only  eat 
such  as  ia  of  f;oud  quality.  He  feeds  slowly,  and  languidly, 
ewocially  if  he  has  been  ridden  at  all  hard.  In  this  case,  he 
oncn  reiuae*  his  food  for  some  time;  and  if  any  cold  water  is 
given  him  is  atuicked  with  shivering,  and  sometimes  with 
looseness  and  colic.  Delicacy,  or  wenkncss  of  appetite,  ia  often 
constitutional,  imd  the  elTecl  of  being  kept  hard  when  a  colt,  or 
of  being  kept  in  cold  wet  situations;  it  may  be  also  hereditary. 
Sometimes  it  is  brought  on  by  too  early  and  immoderate  work, 
and  inattention  in  reganl  to  fct^ding.  In  all  (hose  cases,  the 
liorse's  work,  eA]H-ciuliy  with  n-Rard  to  the  pace  he  is  riilden  at, 
the  quality  of  his  food,  the  u-mperaturc  of  his  water,  and  all  those 
attentions  which  constitute  good  grooming,  must  be  constantly 
observed.  WIten  such  a  horse  happens  to  be  worked  harder 
than  usual,  the  extra  labour  must  be  compensated  for  by  extra 
attention:  his  water  should  have  titc  chill  taken  off;  luid  if  a 
handful  of  fine  wheat  floor  were  stirred  into  it,  it  would  be  still 
bi-tliT,  especially  if  the  bowels  are  rather  loose.  A  cordial  ball 
may  bo  useful  on  stich  occauons,  or  a  moderate  dose  of  warm  ale.

ia  a  stable,  his  diet  must  be  carefully  aliendetl  (o.  Thit  should 
be  rather  opening,  and  such  as  the  horse  apjieani  to  reliiit: 
vetches,  or  other  grecii  food,  arc  perhaps  the  best.  Oood  SMeet 
bran  is  an  excellent  ihing  lo  keep  the  bowels  cool  and  open, 
and  may  ite  rendered  nutritious  in  almost  any  degree  by  the 
addition  of  good  fre<li  bruise*!  ottts,  or  mall.  A  small  quantity  af 
good  sweet  and  clciui  oah^,  thrown  into  the  manger  now  and  dies, 
will  often  induce  n  horse  to  Htxl,  wlten  there  is  want  of  appetite; 
and  a  very  fimall  <{uaiitity  of  (he  Hwcctoiil  hay,  given  occasionally, 
is  j^nerolly  tsklen  uiih  great  relish. 

Young  hor*cs  often  fall  off  in  iht-ir  apiK-tite*  during  (he  time 
of  culling  teeth.  At  this  period  chere  h  often  a  Korenoc«  of  the 
mouth,  in  which  the  mucous  membrane  of  the  ntomach  and 
boweU  secmii  to  j>ai'ticipHle.  In  such  cases  the  wiuit  ofappcliir 
U  generally  attributed  Id  the  lampns,  or  a  s<velling  or  fuhina  iu 
the  roof  of  the  mouth,  adjoining  the  front  teeth;  because  ibc 
honte  is  sometimes  observed  to  mangle  his  hay.  as  it  ia  termed, 
that  is,  he  pulls  it  out  of  the  rack,  and  after  chewing  it  a  hide 
while  throws  it  out  again.  The  common  remedy,  if  such  it  may 
be  called,  is  the  application  of  a  n-d>hot  iron  to  the  part,  aiw 
burniitg  out  tl>e  prominent  part,  or  lamuaB ;  but  this  is  never 
necessary.  Alt  young  horses  Itavc  that  fulne^  in  the  roof  of  the 
monlh  which  is  named  lampas,  and  it  never  interferes  with 
their  npixrtite,  or  the  chewing  or  gullieriug  of  their  food.  There 
may,  however,  be  &ome  (legrL-e  of  tenderness  about  the  gums  SI 
the  lime  of  teething,  when  soA  Ibod,  such  as  brnn  mashes,  should 
be  given  for  a  few  lUy*;  mid  as  the  stomach  anil  bowels  am

•nd  an  emollient  clyster  tlimwn  up.  When  there  is  costivcnca, 
or  slimy  dtuig,  a  laxative  drench  may  be  given  also,  compoMd 
of  4  03t.  Rjuom  salt;  2  drechms  of  carbotuiie  of  soda;  1  pint  of 
warm  water :  ami  4  oz.  of  castor  oil. 

If  the  mouth  appears  very  tender,  or  sore,  it  may  be  washed 
or  syrin^d  with  a  luiiuti,  composed  of  alum,  honey,  und  water. 
Keeping  a  horse  on  new  oats,  or  new  hay,  is  often  loUowed  by

be  does  not  break  wind  much,  or  stale  very  largely,  an<l  his

and  found  ilml  niiK-  horses  were  consuming  nine  Iiimdred  of  liay 
a  week,  witli  an  allowance  of  two  pecks  of  corn  a  day  each ;  that 
b,  nearljr  sixteen  pounds  a  day  for  each  liorse.  In  anoUier  coach 
concern,  wtwec  horses  1  irxaniincd,  (he  allowance  was  eeven 
liuiidrcd  of  hay  u  week  for  fight  liorset,  and  the  same  quantity 
ofroni.  In  thi.i  e^tabhvhnK-tit  a  very  usdul  rule  was  uniformly 
actoptvd,  which  WBi',  to  kt^cp  the  hoivcx  wiihout  food  two  hourt 
before  they  started.  This  tin-  owner*  Itad  been  taught  by  tlie 
loos  of  three  or  four  horses,  in  comequeiioe  of  working  tJu-m 
witli  too  much  food  in  their  stoniaehs,  aiid  loo  much  dung  in  the 
larji^e  bowolfl.  1  do  not  lliink,  however,  that  a  horse  in  regular 
mail  work,  which  eala  two  pecks  of  oata  a  day,  is  capable  of  rat- 
ing sixteen  pounds  of  hay,  and  that  there  mu&t  have  been  a  great 
deal  wiuted.  I  remarked,  when  four  of  them  were  taken  out  to 
put  to  the  coach,  tlml  there  were  some  oats  led  in  the  manger, 
perhaps  from  a  quarter  lo  half  a  peck;  so  that  it  was  eriwDt 
(hat  the  allowance  both  of  hay  and  oats  was  more  (Iian  they 
could  make  nsc  of:  and  if  wc  snppoM-  that  six  pounds  of  hay  per 
day  might  have  been  laken  from  each  horse,  fur  the  benefit 
of  hi»  ht-alth,  it  would  have  f^uv<'d  the  proprietor  three  hundred 
of  hay  a  week,  or  nearly  eight  lon»  a  year. 

A*  coach  propriecorti  purchase  horses  of  all  ages,  and.  conse- 
quently, of  various  habits  an<l  appetiti.-*,  al«o  with  slomaclis  and 
boweU  of  various  ea[»aciiies,  and  greatly  divenifxHl  «ith  regard 
to  condition,  or  nervous  uud  muscular  power,  they  would  find 
great  advantage  fi-om  altending  to  a  hor»e'.t  feeding,  until  tlicy 
are  jxTfecily  acquainted  with  the  state  of  his  ap]>clitc,  and,  coi>- 
sequently,  of  his  stomach  and  digestive  urgtms  generally.  Thii 
would  enable  them  to  keep  their  horses  in  tlie  be*l  condition,  u 
they  would  soon  discover  an  inordinate  or  depraved  a[i{H-tite,  and 
l)e  enabled  to  correct  it.  Thia,  however,  is  scarcely  ever  done. 
'Ilie  general  opinion  anioiig  persona  concerned  with  horMs  is, 
(liat  they  eannot  eat  loo  much.  Bad  feedei's,  or  horse*  with 
weak  appetites,  are  sure  to  be  found  out,  lieeause  ll>ey  soon  be- 
come unable  to  perform  the  work  ilwt  is  expected  of  them ;  but 
tlic  cflH-cts  of  over-feeding  are  almost  always  attributed  to  other 
caitu's;  and  physic,  cordials,  bleeding,  diui-etics,  in  short,  every 
thing,  except  the  most  simple,  economical,  and  effectual  remedy, 
is  employed  for  their  removal.  When  a  horse  tJierefore  is 
observed  to  eat  a  great  deal  of  hay,  and  to  devour  his  litter  if 
tltere  bo  no  hay  before  him,  and  especially  when  he  is  found  to 
be  dull  and  sluggiith,  or  thick-winded,  he  should  be  prevented 
from  eating  so  much  hay.  This  can  be  doiK-  ut  first  by  w«tglt- 
ing  out  a  certain  quantity  daily,  and  dividing  it  into  three  por- 
tions. If  aHer  eating  his  allowance  he  is  found  to  eat  his  litter, 
he  should  be  siiU  further  K-«traiiie<l  by  a  muxxle.  A  hoi-sc  bc>

in  hU  work,  was  left  in  the  stables  for  two  or  three  days'  rett. 
On  the  second  day  )>e  was  aitaeked  with  violent  colic,  which 
terniinaied  fatally  in  a  few  hours.  On  oi>ening  the  body,  the 
slomacli  was  found  loaded  with  undigested  food,  and  the  bowels 
distended  with  excrement  and  air,  and  highly  inflamed.  It  was 
evident,  then,  that  what  wa«  intended  for  ilie  horse's  bcnelit  was 
the  cause  of  his  death ;  tliat  is,  leaving  him  in  the  stable  to  eat 
and  drink  a%  much  as  he  liked.  This  horse  laboured  under 
another  disadvantarre  biJsi'U-s  that  of  an  immwleralc  appetite; 
there  were  nlmr])  edge*  on  his  grinding  tcfth,  which  rendered 
nia.>(lication  rather  painful,  and  cau.M^I  him  lu  swidlow  tonie  of 
his  com  and  beans  uiichewi-d. 

1  once  examined  a  horse  that  died  of  the  fret  or  colic,  and 
found  his  bowelsBO  enormously  loaded  (and  hia  stomach  also  pretty 
full)  that  I  was  induced  to  inquire  how  the  horse  had  been  fed. 
Tlie  man  who  had  the  care  of  him  informed  me  that  the  night 
before  the  tmrse  was  taken  ill  he  put,  as  near  as  tie  could  judge, 
thrcf  quarters  of  a  hiiiidred  of  bay  in  tlie  rack  for  two  cart 
horsirt,  and  that  he  had  given  thi»  horse,  in  mldition  to  a  shar« 
of  thin  allowance,  about  halfa  peck  of  barley  :  ihit  ap[K-ared  to  bo 
the  usual  allowance  lor  the  two  horses.  Horses  that  eat  to  much 
ae()uir«  a  permanent  enlargement  of  tilomach  and  boweli,  and  a 
constant  craving  fur  water  as  well  as  food,  generally  preferring 
dirty  or  muddy  water,  and  seldom  refusing  the  most  GItliy.  I 
know  now  a  team  of  earl  horses,  at  Wells,  that  01*6  allowed  to  eat 
as  much  hay  and  drink  as  much  water  as  thev  like.  The  pond  at 
which  (In-y  drink  is  formed  by  Uio  rain  which  Hows  from  the 
roof  of  llie  stable,  and  from  the  court,  where  there  is  a  htrge 
<lung-)>cap  constantly  kept,  the  drain  of  which  flows  into  the 
{tond.  The  water  is  always  of  a  dark  or  dung  colour,  like  an  in> 
fusion  of  horse  dung,  and  would  Ik-  found,  I  should  think,  excel- 
lent manure.  Mr.  Oarrod,  the  proprietor,  assured  me  that  his 
waggoner  had  repeatedly  tried  to  make  them  drink  at  a  running 
stream  about  a  mile  from  Wells,  when  they  were  returning  from 
a  journey  and  thirsty,  but  they  always  refused;  yet  as  soon  at 
they  got  )u>me,  and  were  p<-rmitted  to  go  lo  this  fililty  pond,  thvy 
drank  witli  the  grvatc«t  avidity.

quantity  of  food  of  an  indigcalible  nature.  It  iB&eldom  observed 
until  ilie  symptoms  are  fully  establislied,  for  the  animal  is  induced 
to  continue  feeding  as  long  as  tlie  stomach  is  capable  of  holding

October.  'Hterc  i»  mrely  any  symptom  of  acute  pain  wi  ni

degree  whatever,  nor  is  respiration  or  breathing  much  slfected, 
But  when  the  disorder  has  proceeded  to  some  len«h,  botli  the 
pulse  and  the  breathing  become  affected,  and  I  hare  knovm  it  trr*

or  upon  apoplexy. 

The  Symptomf  of  this  disorder  are.  great  heaviness  and  drow- 
siness, resting  ihe  nose  in  the  manger,  or  iitclining  the  head, and 
resting  the  cheek,  or  bearing  against  the  wall.  The  head  k 
forced  against  the  manger,  or  rack,  or  the  no«c  between  ihr 
rack  stavfs.  In  this  way  tltc  eyes  an<l  face  are  often  much 
bniiM-d  and  swollen.  'Hie  horse  staniU  with  ht*  fore  teg  much 
tinder  him,  auix-urin";  to  give  way  eveo'  now  and  then,  m  if  Iw 
would  fall.  There  m  an  appearance  of  conrulsive  twitching  of 
tlio  muscles  of  the  neck  and  chc«t.  There  it,  too,  a  great  degivo 
of  yellowness,  approaching  to  ortnge-colour,  of  the  ntembrann 
of  the  ej'es,  and  often  a  yellowness  of  the  mouth  also.  Urine 
•cnrcx-ly  any.  and  liif^h-citlonred;  Kometimex  none  is  voided,  and 
oceasiutiiitly  it  is  distharged  by  a  convulsive  effort.  Sotnetimn 
the  disorder  is  ntteniled  with  locked  jaw,  ending  in  paralysis  and 
death.  In  the  early  stage  of  the  disorder  the  horse  is  often 
suddenly  roused  by  opening  the  stable  door :  Ite  lifm  op  his  head, 
and  sometimes  neighs ;  but  this  is  only  n  momentnrv  effort. 
When  the  disease  liappena  iit  ^rajtSg  the  animal  is  generally  finind 
lorcing  his  head  ogninst  the  la-dge,  or  a  gate,  or  moving  about 
in  a  state  of  stupor  and  apparent  insensibility.  Some(ime»  be 
is  found  struggling  in  a  ditch,  and  in  that  situation  he  often 
di«-s.  In  tl)c  low  country,  in  the  neigliboiirliood  of  Glastonbury 
and  Wediooor,  the  dismrder  wait  very  prevalent  before  the  en* 
closures  were  made,  and  the  land  drained,  it  generally,  or 
always,  ended  fatally  ;  but  the  horses  lived  sometimes  a  month  or 
two  under  the  symptoms  of  the  disorder,  but  in  a  less  degree. 
It  is  pi-obahle  ihe  disease  was  thus  slow  in  its  progress,  from  ttic 
tioniacli  not  being  so  loaded  as   in  the  ca«es  which  commonly

occur.  Tlic  bor»es  generally  at  lengtli  fell  into  a  ditdi,  and 
diet).  The  disorder  was  attributed  by  tbe  proprietors  of  the 
country  lo  the  plant  namctl  ragwort,  which  cattle  iveie  observed 
to  mU  fre«-lv,  and  were  ta'id  to  die  in  con»e(juence,  in  a  Bimilor 
maniwr  lo  liunies.  'Flic  truth,  however,  appears  to  bC)  that  the 
dbordcr  wait  brought  on  by  Ok  coldness  or  the  situation,  and  the 
poor  k«p  or  rery  bad  Imy  tltai  it  goiiernlly  gircn  to  homes  and 
cattle  in  tliat  country;  for  it  wa«  ob»cr%-ed  that  sliwp  ale 
greedily  of  ragwort,  and  never  aufFored  from  it :  but  tliey  would 
eat  iliu  plant  during  itie  Uni  year  only  of  it*  growth,  when  il 

t  tender  and  succulent,  while  cattle  and  horsea  were  observed  to 
t  it  in  ilie  second  year  of  its  growth,  when  the  stalks  become 
large,  and  of  course  diflicult  ol  digestion.  II'  Iwrscs  liad  but 
UtiW  else  to  eat,  and  were  thus  compelled  lo  eat  such  indigestible 
fond,  tin-  di«ca<c  inigbt  have  been  so  produced;  but  the  buy  in 
tliat  country  is  generally  bad,  and  tlie  country  low,  open,  cold, 
and  damp,  and  llie  honc-^  and  cntlU-  ofcourw  unbenlthy. 

Since  the  liind  luvt  been  drained  tbe  grawi  anil  hay  Iwve  bci-n 
improved,  and  the  siaggen  veldoni  occur.  Some  time  Hince  I 
received  a  letter  from  a  gentleman  of  Swansea,  in  which  lie  >nj 
that  a  disease  has  many  tinies  occurred  among  the  horses  thn 
work  in  the  mines,  resembling  stomach  staggers,  but  in  a  more 
violent  form.  It  has  bpen  so  destructive  at  times,  that  one  pnn 
prictor  lost  more  than  a  hundred  horses  by  it.  It  unt 
proved  fnia! ;  and  though  it  was  carefully  investigated,  no  satis

probablr  that  it  was  either  contagious,  or  caused,  like  oth«r  epi- 
tk-mic  dl^ajK-s  by  some  peculiar  state  of  the  air  with  which  we 
arc  unacquaiiXccl. 

Gil)«on  rdatcs  a  case  of  Ktomadi  »tnggcrs  which  occurred  At 
grass.  "  Oh  opening  tlic  botly,"  he  wiys  "  1  was  greatly  sur- 
priM<<I  to  find  \m  ^tonindi  und  all  hi»  gut*,  both  larf;e  and  uniull,

for  all  tlio  alinicni  iluii  woa  in  ilw  »iotnaclii  and  (h<-  dung  in  the 
bowelii,  from  one  end  to  the  other,  wa.4  entirely  dry  and  witliout 
■noiaturc,  and,  before  ihcy  were  ojicnedt  appeared  as  hanl  and  as 
full  crammed  as  a  Bologna  sausage,  without  the  least  softness  or 

S'ielding  in  any  part.  The  matter  contained  in  ihcm  was  no 
ess  extraordinary,  the  stomach  being  filled  with  acorns,  sloes, 
oak-lcavc8,  and  such  otlier  things  as  lie  could  pick  up  about  tlic 
liedges ;  some  green  and  some  withered.  The  contents  of  the 
guts  were  chiefly  leaves,  ncitlier  well-eliewcd  nor  digested,  with  a 
mixture  of  grass.  But  tlierc  was  little  or  no  grass  in  his  stomacht 
but  chiefly  acorn  cups  and  loaves.  This  horse  had  been  turned 
into  a  very  rank  afler-ninnsh,  nnd  had  probably  acquired  a  de- 
praved apjietite,  which  ledhini  to  eat  indigestible  and  astringent 
food." 

The  horses  which  I  have  seen  in  this  complaint  have  generally 
been  larmers'  horses  that  have  been  kept  hard,  and  worked  hard, 
and  in  whom  the  stomach  has  been  gradually  weakened,  and  at 
length  brought  to  that  ultimate  degree  of  weakness  which  is  named 
pftlay.  In  K-vcral  that  1  examined,  the  vi-ssels  of  the  brain  were 
not  lofldol  inn  remarkable  degree;  tbe»lomach  only  was  affceled, 
and  evidently  paralyst-d.  The  disense  is  scarcely  ever  iiotice<l  in 
this  clasaofhor«e»,  until  iiiitabifolulely  incurable.  Many  of  those 
ne»  were  attacked  at  grat^  and  almost  always  in  low  wd 
ituattoits,  where  the  grau  was  rank  and  abundant.  It  is  not 
ilikely  tital  in  such  i<iiuatiun$  the  cold  night  air  and  fogs  con- 
ibnie  something  to  tl»e  increase,  if  not  to  tlio  production  of  the 
disorder.  In  the  neighbourhood  of  Kxeter  tht-  disease  hiis  at 
limes  been  very  common,  especially  in  low,  open,  wet  siiuationn, 
^  in  the  parish  of  Stoke,  Kxiuinsler,  and  Dawliih.  I  liave 
cured  several  cases;  but  in  these  the  disorder  was  taken  rather 
early,  and  the  horses  were  in  tolerable  condition,  and  had  been 
,ept  in  a  stable  on  ffood  food.  In  none  has  a  cure  been  eliected 
ithout  a  cousideraulo  diiicharge  from  the  bowels  of  excivment 
iiet  appeared  to  have  been  pent  up  in  them  for  some  time. 
In  establisltracnts  where  horses  are  worked  &irly  and  pro- 
perly fed,  I  liavc  scarcely  ever  known  this  disorder  happen.  Not 
a  single  case  occurtx-d  in  the  Itoyal  Dragoons  during  the  lime 
I  was  veterinary-  surgeon  to  the  regiment ;  nor  in  >Ii'.  Ituisell's 
establishment  in  Exeter,  whose  horses  I  attended  for  many  years. 


IM 


DISSUES  or  TSE    HOBftE. 


I  atn  inclined  to  think  tite  disease  is  not  so  prc^-alont  as  it  wti 
Lweiity  years  sinc« ;  and  this  may  Ik  on  ing  to  an  iini>roveuieoi 
iu  ihtf  method  of  keeping  and  feeding  horses.  Probablj,  too, 
tlie  great  progress  that  has  Ix-en  tnaoe  in  tlic  cultivation  and 
draining  oflow  marshy  land  may  haw  contributed  to  thedecrcsM 
of  the  disorder. 

As  Mion  as  stomacli  ilafEgrrs  aro  oh»crred,  the  horse  should  he 
bl«d  in  ordw  to  rHtero  the  head  in  some  degree;  but  the  prin- 
cipal object  is  to  enable  the  stomach  to  get  rid  ol'  the  losil 
vrliidi  op|>rcss»  it.  Varioux  rcim-die*  liave  br«n  propowd  far 
this  purpose.  'Ilto  beat,  1  bvliew,  are  piii^tivc*  joined  silk 
cordials  and  stimulanUi  and  small  quantities  o(  wann  water  rce> 
ijncutly,  in  order  to  torien  the  ronicnts  of  iIm;  stomach.  Clysun 
of  aall  aiid  water  are  tiierul  idiKt,  and  should  Ik-  thrown  up 
MTonl  time*  a  day.  Tlie  disease  is  often  iucurabltt,  probohly 
firom  a  want  of  early  attention. 

When  incdicinn  cannot  be  readily  procured,  two  or  three 
tablespoon fu la  of  flour  of  mustard,  and  diree  or  four  ounces  el 
comnmii  salt  may  be  tried.  On  whatever  eame  stomach  alaggen 
may  depend,  I  think  it  a  useru)  precaution,  ai;  soon  as  thv  dbeofC 
has  made  ils  up|>earatice,  to  remove  other  lioises  from  the  situ- 
ation ;  and  if  there  is  the  slightest  ground  lor  supposing  that  the 
manner  of  feeding  the  horses  has  contributed  to  it,  that  likesrise 
should  be  dianged,  I  would  advise,  also,  a  dose  of  warm  or 
Btonwchic  physic  being  given  to  the  other  borsrs,  to  iinoron 
lb«  Mate  or  condition  of  ilie  digesiirc  system.  Some  relief  may 
be  afforded  In  stomach  staggers  by  nlacing  a  cask  with  a  link 
stnw   ufton  it,  lor  tlie  Itorse  to  rest  his  liead  upon.

A  table-spoonfut  or  two  of  common  salt  may  also  be  added 
three  or  four  times  a  day.  The  horse  should  be  drenched  and 
clyatered  during  the  night  as  well  as  the  day ;  in  short,  without 
unremitting  attention  success  must  not  be  expected. 

[This  disease  has  become  considerably  less  frequent  than  when 
the  previous  account  was  written  by  the  author,  although  then 
he  states  it  was  not  bo  common  as  formerly.  The  cause  of 
this  must  be  attributed  to  the  better  system  adopted  in  feeding 
borses  at  the  present  day.  Formerly  it  was  customary  for  agri- 
cultural horses  to  go  from  six  in  the  morning  till  four  in  the  aner- 
-noon  without  either  food  or  water,  and  then  to  be  allowed  a  large 

Quantity  of  food  without  water.  Now  their  daily  work  is  either 
irided  into  two  periods,  or  otherwise  they  are  allowed  a  little 
food  in  the  middle  of  the  day.  Thus  their  stomachs  never  being 
so  empty,  ihey  no  longer  gorge  themselves  to  the  same  extent, 
and  the  disease  is  therefore  much  lees  frequent.  When  the  dis- 
ease occurs  at  grass,  and  particularly  if  a  number  are  attacked 
together,  it  is  owing,  in  my  opinion,  to  some  poisonous  vegetable. 

In  a  form  in  Hiunpshire,  about  two  years  since,  in  the  course 
of  some  months,  three  or  four  horses  died  of  a  disease,  somewhat 
■imilar  to  that  described  in  the  account  from  Swansea. 

There  was  great  drowsiness  and  lethargy  manifested,  the  horses 
were  weak  and  sta^ered  in  their  walk,  and  the  membrane  of 
the  nostrils  and  eyelids  was  pale. 

T^e  next  case  that  occurred  was  sent  to  me,  and  it  slowly 
recovered  after  a  fortni^t's  treatment,  consisting  chiefly  of  tonics 
and  stimulants  in  order  to  rouse  the  system  into  greater  action. 

This  horse  had  for  some  time  past  been  feeding  on  spring 
vetches,  which  contained  an  immense  quantity  of  weeds. 

Whetlier  this  was  the  cause,  I  cannot  say ;  but  at  any  rate  it 
appeared  highly  probable  that  the  disease  was  owing  to  some 
poisonous  substance  calculated  to  depress  the  vital  powers. 

With  regard  to  the  Treatmmt  of  stomach  staggers  when  pro- 
ceeding from  distention  with  food,  in  addition  to  that  recom- 
mended by  Mr.  White,  it  would  be  advisable  to  pour  liquids  into 
the  stomach  by  means  of  Read's  patent  syringe,  so  as  to  dilute 
its  contents,  and  if  possible  to  evacuate  a  portion  of  it  by  these 
means.  Instead  of  aloes,  it  would  be  advisable  to  administer 
croton  oil  in  doses  of  from  twenty  to  forty  drops,  not  only  be- 
cause this  medicine  is  so  much  smaller  in  bulk,  but  alao  because 
its  action  is  quicker  and  more  immediate  on  the  stomach  and  small 
intestinea. — Ed.]

DISEASES    or   THE    UOWELS. 

Infiammatiott  oftht  B»KtU,  Erderiti*,  PeritonitU,  jr. 

[THEitR  arc  thrcv  varieties  of.  iiifUinimation  of  the  bovelt: 
enteritis,  or  iiifltunmution  of  ihe  muscular  coat;  periionitu, «r 
iiiflnmniatioii  of  the  peritonea]  coat;  and  dyaeaiery,  or  iitflam- 
niati<>ii  of  (he  niiicoiis  or  internal  ooat. 

'I1ic  two  Rnt  lire  gciu'i-nlly  connected  together,  at  Iea«t  one 
coal  ii  rarely  aflvcteu  witliout  in  some  measure  involving  tbe 
oUier. 

Cases  of  Entcritit,  Itowerer,  are  far  more  IVequent  tban  those 
oi  Ptritonila.  The  inalancea  in  which  the  latter  exists  as  n  ])i> 
niarv  disease  are  cases,  rollowing  castration,  when  t)te  inflsm- 
mstion  spreads  alone  the  course  of  the  cord  to  the  peritonesl 
memhraitc  in  the  abifomen. 

Tile  si/mpioma  of  peritoiutis  are  somewhat  similar,  iliou;;li 
by  no  means  so  acute  as  in  enteritis,  and  the  treatment  should 
be  pretty  much  the  same. 

Enteritia  may  come  on  suddenly,  and  may  at  once  exhibit  ilir 
most  violent  and  intense  character;  or  It  muy  Ik*  [>rec«^ded  bv 
milder  symptoms,  which  may  exist  either  for  several  hours  or  for 
Several  daj's.  lA'heii  it  is  stow  in  coming  on,  the  &n\  symptotits 
are  dulnees,  want  of  appetite,  and  uneasiness ;  the  pulse  some- 
what quickened,  and  the  horse  occo&ionally  pawing  his  litter. 
When  relief  is  not  obtained  tn  this  stage  of  tt>e  disease,  tlir 
symptoms  become  aggravated,  the  pain  greater;  the  Iwrse  lying 
rluwn,  siretchinfT  himself  out,  and  struggling  violently,  rho 
pulse  usually  at  fintt  distinct,  altliunijh  (juick,  lK-coni»  qutckei' 
and  weaker,  nnd  almost  impercopliblo.  The  bowel*  are  con* 
atipated,  and  the  dung  coated  with  n)ucu#.  The  legs  and  ears 
are  cohl,  tlie  mouth  hot,  the  membrane  of  the  evelids  highly 
injected,  and  the  lii-eathiiig  greatly  aceelei-ated.  This  Htoge  of 
the  disease  rarely  laxt*  long:  unless  relief  be  obtained,  deaili 
usually  cIw(,-«  the  se4.*nc  in  the  course  of  six  lo  eighli^n  hours. 
When  such  in  the  cam;  the  sympionis  beeome  more  disire^inj;. 
ibe  horse  lying  dowiii  and  rniely  rising,  but  struggling  almost 
in  a  frantic  sute,  though  with  diminished  strength ;  at  length 
cold  sweats  break  out,  and  the  mouth  feels  cold,  and  death  soon 
follows.  In  some  instances  I  have  known  ilie  animal  contlimu 
his  stniggles  till  within  a  few  minutes  of  bis  death,  and  in  otliers 
the  violence  of  the  f>ymploms  has  disappt-aied  for  some  hours 
before  the  liulal  termination.     In  these  latter  cases  tbeaitendanU 


INFLAMMATION   OF  THE   BOWELS.  161 

usually  imagine  the  horse  to  be  considerably  better,  and  expect 
his  recovery;  but  the  practitioner  finds  that  the  pulse  is  imper- 
ceptible, the  extremities  obstinately  cold,  and  anticipates  what 
he  surely  finds,  dissolution  in  the  course  of  a  few  hours. 

The  tymptamt  of  enteritis  somewhat  resemble  colic,  and  indeed 
the  disease  is  termed  by  farriers  the  red  colic. 

It  is,  however,  of  great  importance  to  distinguish  the  two  di&- 
eases,  fer  the  treatment  of  colic  would  be  highly  injurious  in 
a  case  of  enteritis.  It  has  been  stated  that  a  horse  will  not  roll 
on  his  back  in  inflammation  of  the  bowels ;  hut  this  is  erroneous. 
The  chief  distinctions  are  these, — in  enteritis  the  pain  is  con- 
stant, though  not  at  all  times  equally  severe ;  whilst  in  colic  the 
pain,  thougn  more  violent  than  in  enteritis  during  the  paroxysms, 
yet  disappears,  or  nearly  so,  between  them.  There  is,  too,  an 
important  difference  in  the  pulse,  which  in  enteritis  is  constantly 
quick ;  whilst  in  colic  it  is  but  little  increased,  except  during  a 
paroxysm,  after  which  it  subsides. 

The  causes  of  enteritis  are  (in  addition  to  natural  weakness  of 
the  part  aifected  which  induces  one  horse  to  receive  the  disease 
more  readily  than  another,  though  exposed  to  the  same  exciting 
cause),  over- exertion,  exposure  to  cold,  particularly  standing 
in  water,  or  passing  tlirough  streams  in  a  state  of  perspiration, 
and  standing  still  atterwards.  To  which  may  be  added  drinking 
largely  of  cold  water  when  heated,  and  sul»isting  on  unwhole- 
some  food. 

TVeatment.  —  Having  properly  examined  the  case,  we  should 
immediately  have  recourse  to  bleeding,  and  that  as  extensively  as 
possible :  for  this  purpose  a  large  opening  should  be  made  in  the 
jugular  vein,  or  one  on  each  side,  and  trom  six  to  eight  quarts 
taken  as  quickly  as  possible,  continuing  the  bleeding  till  the 
pulse  becomes  almost  imperceptible.  The  bowels  Ijeing  costive, 
the  dung  should  be  removed  by  back-raking,  and  a  copious  in- 
jection thrown  up.  A  pint  and  a  half  of  linseed  oil  and  one 
drachm  of  powdered  opium  may  next  be  given,  and  a  half  pint 
of  the  oil,  with  half  a  drachm  of  opium,  may  be  repeated  every 
six  hours,  till  the  bowels  are  relaxed ;  the  injections  being  also 
frequently  repeated. 

The  abdomen  should  he  fomented  with  very  hot  water,  which 
should  be  continued  tor  some  time ;  and  it  will  afterwards  be  very 
useful  to  apply  hot  sheep>skins,  just  removed  from  the  dead 
animal,  to  the  abdomen,  the  woolly  side  outermost.  If  these

DISEASES    OF   THE   BOWELB.  163 

The  causes  of  diarrhoea  are,  over-exertion,  exposure  to  cold, 
drinking  very  freely  of  cold  water,  and,  still  more  frequently,  an 
over-dose  of  physic.  Horses  with  short  ribs  and  light  carcasses, 
usually  called  washy  horses,  are  predisposed  to  this  disease,  and 
ID  them  anything  which  disturbs  the  system  generally  is  almost 
sore  to  affect  the  bowels.  Some  years  since,  when  it  was  the 
custom  to  administer  eight  and  ten  drachms  of  aloes  as  a  common 
porgative,  superpurgation  was  extremely  frequent,  and  hundreds 
of  horses  died  in  physic,  as  it  was  termed. 

T^taimaU. — If  purgation  is  the  only  symptom,  and  ther«  is 
no  active  inflammation  present,  the  mischief  is  readily  stopped 
by  the  administration  of  the  following  medicine,  in  thick  gruel 
made  from  wheat  flour :  — 

Powdered  opium 1  dr. 

Powdered  catechu -2  dr. 

Prepared  chalk 1  oz. 

Even  if  inflammation  is  present,  we  had  better  administer  the 
same  medicine,  either  in  gruel  or  in  boiled  starch,  and  repeat  it 
every  four  hours  until  the  purging  ceases;  half  an  ounce  of  pow- 
dered gum  arabic  may  be  added  to  the  medicine,  or  after  a  while 
substituted  for  the  catechu.  The  body  should  be  kept  warm 
by  plenty  of  clothing,  and  the  legs  encased  in  flannel  bandages. 
The  abdomen  should  be  fomented  with  warm  water,  or  sheep- 
skins applied,  as  in  enteritis.  Gruel,  starch,  or  arrow-root  should 
be  administered  frequently ;  and  if  there  is  any  Rppetite,  a  little 
sweet  hay  should  be  given,  but  bran  avoided.  Bleeding  in  this 
disease  is  rarely  prudenL — Ed.] 

Dtfientery,  Molten  Grease. 

[The  mucous  coat  of  the  bowels  is  liable  to  another  disease, 
which,  though  more  frequently  existing  as  a  symptom  of  other 
inflammations,  such  as  that  of  the  lungs  and  the  liver,  or  of  in- 
fluenza, yet  sometimes  appears  as  an  independent  disease. 

The  Symptoms  are,  —  costiveness,  the  fseces  being  small  and 
buttony,  and  encased  in  mucus,  with  large  flakes  and  lumps  of 
this  diseased  secretion  amongst  the  dung.  There  is  no  active 
pain  present,  but  a  dull  heavy  appearance,  quick  pulse,  very  hot 
mouth,  and  other  febrile  symptoms ;  and  when  the  hand  is  passed 
up  the  rectum,  it  is  found  much  hotter  than  common. 

The  mucous  membrane  of  the  alimentary  canal  is  evidently 
affected.  In  diarrhcea  the  muscular  coat  of  the  intestines  is  af. 
lected,  as  well  aa  the  mucous,  and  there  is  consequently  increased 
peristaltic  action.  In  dysentery,  the  mucous  coat  only  is  affected, 
though  not  in  the  same  manner  as  in  diarrhoea.  It  is  in  a  highly 
febrile,  rather  than  in  an  inflammatory  stage ;  but  its  action  is

The  TreatMrnt  must  consist  in  bleeding  largely,  if  the  pulse

[Tberk  lias  been  much  difPerettce  of  opinion  as  to  the  nature  and 
euiM  of  (he  alfeciioiw  re<-ogn)sed  under  the  above  nsntes ;  some 
Cuniiidi-riiig  them  ax  one  disease,  otherd  »e|Mralii)g  them  into  nu- 
merous diviiioiiH.  Hut  without  eutei-jti^  into  (Ik-sc  diapuiN,  or 
making  more  distinctions  than  are  absolutely  necessary,  1  con- 
sider tiiere  are  three  varieties  of  ihe  disease,  which  it  is  import- 
ant to  distinguish, — spasmodic  colic,  llatuleni  colic,  and  colic 
ariting  from  the  ohsiruciion  of  the  food. 

The  Sywt/rfnwi*  of  the  first  and  second  variety  arc  very  similar. 
The  horsi-  is  very  uneasy,  paws  his  litter,  looks  round  to  his 
(tank*,  sometimes  endeavours  to  kick  his  belly,  gathers  up  Im 
hind  legs,  and  tails  down  railicr  suddenly,  rolls  upon  his  hack, 
xiiddenty  gets  up  again,  and  appears  in  extreme  [win.  The  pulse 
is  in  its  natural  stale,  and  the  inner  surface  of  lh<^  eyelids  is  not 
unusuallvrcd.  'Die  disorder  comes  on  suddenly,  t)>eatiimal  being 
prcvio»i»[y  in  good  health.  The  liorsc  is  sometimes  costive,  bin 
not  often,  and  in  Komc  caj*es  the  dung  is  rather  loose. 

In  flatulent  colic  there  is  a  considerable  distention  of  the  ab- 
domen, from  the  proiluclion  of  gas  in  the  intestines,  whicli,  in 
spasmodic  colic,  is  not  found  to  exist.     In  the  former  the  large  in- 


tpsiines  and  ll>e  stonmcli  *  are  tmtalty  the  erat  of  disease ;  in  the 
latter,  its  situniion  is  more  frequently  confined  to  llie  aniall  intes- 
tines. 

The  symptoms  of  tliese  cUseases  arc  subject  to  great  variety  as 
to  tlicir  severity,  l»eing  sometimes  so  ^iglil  as  to  dtjappcar 
witliout  any  trraiment,  and  at  other  times  so  violent  as  to  render 
the  )>orse  almost  frantic.  I  was  called  to  a  horse  some  time 
since,  that  had  been  taken  with  the  fret  during  the  night;  and 
before  I  reached  itie  stable  he  had,  in  the  violence  of  hia  sirugf^lM, 
knockt-d  out  several  of  his  front  teeth,  and  disfigured  hiiiu>t-lf 
dreadfully,  his  eyes  being  neatly  closed  from  the  clioct  of  the 
brtiiscs. 

Flatulent  colic  is  produced  by  the  distention  of  (he  intestines 
from  ga*;  it  is  accordingly  very  frequent  in  the  sammer  season 
Willi  Fiorecs  that  are  fed  on  green  food,  and  it  may  also  be  pro- 
duced by  the  indigestion  of  any  description  of  food.  It  is  pro- 
bably the  most  frequent  varietv. 

Ttte  pnin  of  spasmodic  colic  is  immediately  caused  by  tlw 
vtoleiU  contraction  of  llie  muscular  coat  of  the  intestines,  just  as 
the  i[)a«mo<)ic  contraction  of  an  external  muscle  produces  cramp. 

It  is  frequently  occasioned  by  a  draii)>ht  of  cold  water,  parti- 
cularly if  it  be  of  a  hard  quality,  having  sulphate  of  lime  in  il. 
It  may  alto  be  produced  by  univhulcsomo  food,  and  any  thing 
that  disorders  the  stomach  or  inlcslines. 

Some  Imrses  are  particularly  liable  to  colic;  and  in  tliem  it  is 
often  produced  by  causes  that  would  have  no  elTect  with  other 
Imi-kii.  'l'h\»  predisposition  generally  increase*  as  the  animals 
^t  older,  and  in  them  the  disease  usually  proves  fatal  at  last. 

'lliat  vtiriety  of  colic  produced  by  the  obrtniction  of  food  is 
chamcterited  by  symptoms  more  moderate  than  the  other 
viirietie*,  though  they  are  longer  conliiuied  and  usually  nioicob* 
ktinate.  The  horse  lii.'«  down,  but  does  not  rise  again  quickly, 
nor  struggle  90  violently ;  and  the  pain  is  more  continued  than 
iti  the  varietii^  Ix^orc  mcntionait. 

The  symptoms  are  more  like  inflummatlon  of  the  lioweK  but 
dit*rc  ia  little  or  no  increase  of  puW.  There  may  or  may  not 
be  cosliveiiess,  according  to  the  previous  nature  of  ihv  food.

commended for  this  disease,  and  most  of  tliem  are  elTecCual  in

this  disease^  and  it  b  much  better  to  conjoin  several  togcllier 
llian  to  ndminiaier  one  alone :  because  not  only  is  the  compound 
dose  likely  to  prove  more  succesiful,  but  if  it  becomes  necessary 
lo  repeat  it  several  limes,  it  is  less  likely  to  produce  inflammaiion 
than  one  kind  of  medicine  given  in  the  powerful  dose  required. 

If  the  borae  be  not  relieved  in  the  course  of  ten  minutes  after 
tlie  exhibition  of  tlie  medicine,  it  will  be  desirable  to  bleed,  not 
only  in  order  to  guard  against  inflammation,  but  because  blood- 
letting is  itself  a  powerful  antispasmodic,  and  often  oftbrds  itii- 
medlate  relief. 

In  tile  course  of  half  an  hour  lo  an  hour,  if  relief  be  not  o))- 
Liined,  it  will  be  desirable  to  rqicat  the  medicine;  nnd  again  in 
tbe  ccMirsc  of  one  or  (wo  hours  afterwards,  should  tlie  symptoms 
continue  or  return ;  and  unless  the  bowels  nro  relaxed  it  will  be 
desirable  to  administer  apcricnl  medicine  with  the  second  or 
■bird  antispasmodic  draui;hl.  Throe  ounces  of  Uarbadoes 
aloes  powdered  may  be  dissolved  in  hot  water,  and  given  with  a 
[Hnl  ot  linseed  oil ;  adding  to  or  subtracting  from  this  dose,  ac- 
cording to  tiK  strength  and  condition  of  (he  animal.  If  relief 
be  not  obtained  after  the  third  dose,  tbe  cose  becomes  very  dan- 
gerous, and  we  must  be  cautious  as  lo  the  further  ndminislratioii 
of  stimulants.  The  pulse  must  be  watched,  and  the  bleeding  re- 
[lealed  ;  and  with  regard  to  medicine,  it  will  ho  belter  lo  trust  to 
opium  alone,  a  drschin  of  which  may  bo  infused  in  wnter,  and 
giTen  every  two  hours.  By  pursuing  this  phin  of  treatnu-nt  wc 
may  often  accomplish  a  cure  in  the  most  ibuig^TOUS  and  pro- 
tracted cases.  I  met  with  a  cnMc  some  lime  since,  in  which  I 
found  it  ncccstiry  lo  administer  ihne  ilimfs  of  llie  stimulating 
aotis)jasmodic  before  ndvi»i.-d,  to  bli-eii  largely  twice,  to  give  re- 
peate«l  injections,  to  foment  the  abdomen,  and  aflerwiini*  lo  ad- 
minister (he  above  dose  of  opium  every  iwo  hours.  By  which 
peiwcring,  yet  cautious  method,  the  Mymptoiiu  were  eventually 
removed,  and  the  horse  ri-covered. 

Unless  the  horit»^  recover  from  llie  first  dose,  injections  of 
warm  water  bimI  mIi  shonlil  be  fr»-qiifnily  and  copiously  admi- 
nistered; and  if  inllammutioii  be  threatened,  tlie  iibdonien  should 
be  fomented  and  mimulnti-d,  and  indeed  tho  same  means  used 
s$  for  inflammation  of  the  bowels.

When  a  hoi-se  dies  from  the  colic,  which  ta  rarely  ilie  case

IStoitfS  in  the  Intestintf 


Are  not  unfi'e()ucnily  foimd  in  homes:  they  are  usually  dis- 
covered in  iIm;  large  guts;  but  somctimcii,  though  rarely,  in 
the  stomach.  Tliey  are  generally  found  to  consist  of  stony  and 
earthy  particles  mixed  with  the  fowl,  and  having  some  bard 
object,  such  as  a  jiebble  or  nail  licad,  in  its  centre.  These 
calculous  concretions  arc  more  fifqueiii  wlih  millers'  horses 
than  with  otlters,  which  ia  owing  to  the  fact  of  their  being  fed 
extensively  on  bran.  Numerous  uitnule  {larliclcx  of  milUldne 
adltcre  to  tlie  bran,  and  having,  perhaps,  some  accidental 
nucleus,  as  before  stated,  thcv  gradually  collect  around  it,  the 
food  assisting  in  the  formation.  The  shape  of  these  calculi 
de[>ende  ven,'  much  on  the  seat  of  their  aliode ;  one  in  my  pos- 
session, taken  from  the  stomach,  is  extremely  irregular,  and 
consists  of  stony  substance  within,  and  a  softer  spongj'  surface 
externally,  formed  chiefly  by  the  food.  'I'he  snrfiice,  thotigb 
irregular,  like  a  mulberry,  is  covertxl  by  a  black  coat  tiuoolhly 
poliabcd.

Another  calculus  in  my  posseeuon  is  as  rmind  as  a  crickft 
'  bnll*  and  weiglis  upw-ards  of  six  pounds.  It  wss  found  in  tlw 
rvolon,  nnd  had  acquired  its  globular  form  from  rollinif  about  in 
thit  liirge  intestine.  The  Itoi-so  Itad  belonged  to  n  miller,  and 
li»d  beti)  accustomed  to  live  niosllj'  on  bran  ;  he  had  fur  se^-cnl 
years  l>eeii  subject  to  tlie  fret,  but  had  generally  relieved  himwlf 
by  rollins  about.  TIicsl'  symptoms  were  no  doubt  produced  bv 
tl»e  calculus  becoming  wcdf{«l  in  the  smaller  ports  of  the  coloiii 
and  which,  bv  ilio  slru;;;!;les  of  the  animal,  a^in  became  dis> 
i>laced,  and  then  relief  wu«  iifforded.  At  lenjflh  it  was  so  firmlr 
impacted  tlint  it  could  not  l>e  moved.  A  lota!  stoppage  took 
place,  and  nothing  pushed  by  the  rectum  for«cveral  days,  during 
uhicli  the  animal  vvinn**)  much  pain,  lying  down  nnd  rolling; 
but  the  position  in  which  )h>  up|M'ared  most  reltevi'd  wok  tliat  of 
sitting  on  his  Iwuncltc*.  From  tliese  vanoiu  symptomsi  I  fell 
conrineed  that  a  stone  wiu  tlw  cauw ;  and  the  animal  being  dc 
fitroye<l,  llic  large  cntcuhis  was  found  firmly  impacted  in  (lii; 
wcond  cnrralure  of  the  colon,  whence  it  could  g«-t  nrillxT  biwk- 
wards  nor  fbrwayd«.  On  dividing  it  with  n  saw,  a  pebble  ww 
found  to  be  its  nucleuA,  and  it  consisted  of  a  vast  number  of 
rongli  and  smooth  layers  alternately  arranged,  the  external  uiie 
l>eing  rougli. 

In  9ome  instances,  a  vant  number  of  stony  substances  have 
been  found  loose  in  tlie  intestines,  their  weight,  though  not  tlieir 
sixe,  preventing  thetr  poastiig  onwards. 

Some  tiortes  haw  a  depraved  appetite,  and  take  great  (juan- 
tilies  of  earth  when  they  have  llic  opporlunity,  which  cvrtniiily 
must  conduce  greatly  to  the  formation  of  these  Goncretiotu.^£t>.J 

Slranfftilntioti  of  the  Itoirrh. 

[On  the  ititpeclion  of  tlie  bodies  of  horses  that  are  supposed  to 
die  from  colic,  we  sometimes  find  tlie  small  intealiiies  strau- 
gulaled  by  being  formed  into  a  knot,  so  as  to  produce  the  inost 
intense  pain,  and  a  complete  interruption  to  alt  passage.  Some- 
times  a  most  perfect  knot  is  formed  liv  one  portion  of  the  intcs- 
tine  l>eiiig  insinuated  between  a  sort  of  nooee  formed  by  anotlier 
[kortion.  Another  time  we  find  that  a  noose  is  formed  by  a 
slip  of  the  mesentery;  n-bich,  by  some  means,  lias  got  separated 
from  the  rest. 

Another  variety  is  called  intro-susception.  and  consists  of  one 
portion  of  the  intestine  insinuating  itself  within  die  cavity  of 
another.  Sometimes  the  stricture  is  caused  by  a  Guty  tumour 
attached  to  tlie  mesentery,  or  an  enlargement  of  the  mesenteric 
gjand ;  as  related  by  Mr,  W.  Pereivall  m  the  I'tteriitarum,  vol.  u

Anotlier  variety  is  a  strangulation  from  simple  twisting  of  the

No.  a.  is  a  case  related  by  Mr.  W.  Pcreivall.  —  Vi^erinarian, 
vol.  i.  p.  .12(i. 

We  cannot  tell  with  certainly  that 
strangulation  has  Inkcn  place;  but  wc 
may  expect  *uch  w  be  tlic  ease,  when 
we  find  thai  sympiimis  of  colic  conti- 
nue without  rculi*-^i^l[l  til  iipitc  of  all  Ko^j, 
our  trctttincnt.  TIr-  pul»e  in  tlK-sc 
/cases  ts  nut  quick  at  firtt,  nor  for 
8c^i?ral  flours  aftvruartU;  but  the  pain  continues  to  increase, 
and  at  length  inflammation  supervenes,  and  llio  horse  continues 
in  the  greatest  ngoiiy  for  ten  or  twelve  hours,  when  the  inten- 
sity of  the  pnin  beems  to  disappear,  but  iht;  animal  dies  a  few 
boars  afterwards. 

It  is  a  disputed  subjecL  whether  intervaj^nation  is  more  fre- 
quently llir  consetiucncr  of  the  spasmodic  acdon  and  comnvotion 
of  the  bowels  in  eulic,  or  otherwise  the  twisting  of  the  intestttws 
occurs  previously,  nnd  i«  ii*elf  liie  cause  of  even  tlte  esrlievt

strating  whtcti  theory  is  correct;  but  I  am  inclined  to  consider 
that  although  inter vaginat ion  may  be  sometimes  the  effect  of 
colic,  it  more  frequently  arises  from  one  gut  getting  accidentally 
entangled  in  the  other  when  in  an  empty  state,  and  producing 
for  some  time  no  inconvenience,  until  food  enters  and  distends 
it,  and  is  prevented  passing  onwards  by  the  knot.  This,  at  any 
rate,  must  be  the  case  whenever  the  noose  is  formed  by  adven- 
titious substance,  or  by  a  portion  of  the  mesentery ;  which  often 
exhibits  the  appearance  of  having  been  formed  for  a  length  of 
time. 

Intro-susception  is  more  likely  to  be  of  recent  origin,  pro- 
duced probably  by  the  spasmodic  action  of  the  bowels  in  colic ; 
and  so  likewise  when  it  is  simply  a  case  of  twisting  of  the 
mtestines.  It  appears  that  in  the  greater  number  of  instances 
on  record,  the  ileum  is  the  gut  most  frequently  entangled; 
which  may  be  accounted  for  by  the  &ct  of  this  intestine  being 
less  confined  than  any  other.  Next  to  tlie  ileum  is  the  rectum ; 
and  the  duodenum  is  most  liable  to  stricture. 

The^TVeatmmt. —  It  is  impossible  to  ascertain  positively  the 
existence  of  entanglement  of  the  bowels ;  and  if  we  could  do  so, 
in  the  majority  of  cases  our  treatment  would  be  useless.  Where, 
however,  we  have  reason  to  expect  the  existence  of  such  morbid 
formation,  the  treatment  indicated  would  be  copious  venesec- 
tion, freqiieot  injections  of  warm  water  or  tobacco  smoke,  and 
strong  doses  of  opium,  so  as  to  quiet  the  system  as  much  as  pos- 
sible; and  to  avoid  all  food  and  purgative  medicines.  By 
adopting  this  plan,  nature  may  perhaps  right  herself,  and  the 
spasms  being  quieted  the  gut  may  be  released ;  which,  in  a  case 
of  simple  twisting,  is  indeed  very  likely  to  occur. — Ed.} 

Crib-bitiTiff. 

This,  though  only  a  trick  or  habit  which  a  liorse  gets,  and 
which  he  may  teach  another  that  stands  next  him,  especially 
B  young  horse,  may  be  considered  as  a  disorder,  because  it 
renders  him  very  liable  to  indigestion  and  flatulent  colic.  There 
a  no  doubt  that  in  crib-biting  a  horse  swallows  air ;  and  I  have 
seen  a  horse  distend  his  stomach  and  bowels  with  it  in  an  enor- 
wous  degree,  and  he  would  theieby  often  get  the  flatulent  colic, 
and  sometimes  swell  himself  so  that  he  could  scarcely  move. 
The  only  convenient  method  of  preventing  crib-biting  is  to  put 
a  leather  strap  round  the  neck  close  to  the  jaws,  which  prevents 
him  from  laying  hold  of  the  manger :  it  may  impede  his  feeding, 
however,  and  this  must  be  attended  to.  A  muzzle  sometimes 
answers  the  purpose.  £There  are  now  muzzles  invented  that  ad- 
mit of  feeding,  and  yet  prevent  the  horse  opening  his  mouth 
sufficiently  to  seize  the  manger  with  his  teeth.  In  many  cases 
they  prove  very  useful,  thougn  in  some  they  altogether  fail. — Ed.]

WORMS. 

Worms  are  most  coinmonlv  fotnid  in  the  \nvfeh  and  Rtoniach: 
but  iheyare  somctimea  met  with  also  iii  almost  every  part  of  tlie 
body.  I  have  found  them  in  the  windpipe,  in  thp  mesenteric 
arter}')  in  an  nbBCcss,  in  ihc  eubsuinceof  the  abdominal  muBclea; 
and,  according  to  LafoMO,  ihev  have-  been  found  al«)  in  the  pan- 
crealic  and  snhvcirv  duel*.  The  worms  commonly  found  in  the 
stomach  arc  namiil  bolU.  They  are  f^nerally  attached  to  the 
cuticular  or  inseimble  coal  of  the  stomach;  but  sometimet 
clusters  of  them  are  found  at  lite  pylorus,  and  even  io  tbe 
beginning  of  the  fintt  inlMtine,  named  duodenum.  In  one  cnse 
they  were  w  mnntrous  in  this  last  xilnalion  »s  to  ob«lruct  tlir 
puM)!!^  completely,  aJid  cause  the  animar*  dearh.  Botts  are 
H)M>ri,  thick,  recldish  wonu»,  surrounded  witli  short  {>ricklc«, 
which  are  arranged  in  circular  bands  all  over  the  body.  'I1iey 
attach  themselves  firmly  by  two  hooks,  which  they  appear  to 
have  the  power  of  straightening  and  retracting,  of  projecting;  and 
curvating.  Tbey  are  extremely  teiincioua  ot  life,  and  difficult 
to  be  expelled  from  the  stomach,  except  almut  the  month  of  Sep- 
tember, or  when  a  horse  is  tirst  taken  up  from  grass.  At  tliis 
period  they  may  generally  Iw  got  rid  of  by  brine,  or  a  solution 
of  common  mU  and  water,  in  a  dose  of  from  four  to  five  ounce 
of  salt  10  11  quart  of  water.  Tlie  horse  should  \k  kqU  (iistlng 
the  night  l)efoiv  it  b  given;  and  alwut  five  minutes  before  die 
drench  widi  salt  is  given,  let  the  horse  lie  drenched  with  al>out 
a  pint  of  warm  milk,  sweetened  with  honey  or  treacle. 

It  has  been  siip]>ooed  lliat  botls  arc  not  only  innoceni,  but 
even  beneficial,  from  their  being  so  frequently  found  in  the 
liorsc's  stomach  aflcr  death,  when  during  tlic  annnal's  life  no  in- 
convenience was  observed  to  arise  from  them.  That  diey  axe 
sometimes  tiijuriousi  however,  and  fatidly  so,  has  been  clearly 
demons trati-d  by  several  case!  diat  liave  come  under  my  obaerv- 
atton.  Tliey  have  been  known  to  ulc^'rate  and  make  boles  in 
the  stomach.  Gibson,  a  most  respi-clabic  velcrinary  autbor, 
considen;  ihem  as  sometimes  the  cause  of  locked  jaw ;  and 
Mr.  Jnmcs  Clarke,  of  Edinburgh,  has  recorded  one  case  in 
which  they  had  made  an  opening  tlirougl)  the  hone's  stomach 
into  the  undo  men. 

Mr.  Urncey  Clark,  in  his  Treatise  on  the  Botts  of  Horse*,

municated lo  me  by  n  metlkal  ^■ntleman  of  llridport,  who  had 
S;iven  it  him^tir,  and  ha<l  known  il  employed  by  Homo  furriert  in 
m  neigliboiiilxxKl  with  the  moitl  Mrikin]^  effect.  Hii  method 
was  to  give  the  home  l)ie  day  before  about  ^  dracUnis  of  aloe«, 
in  order  to  relax  the  bowels  a  tittle.  He  waa  kept  fasting  during 
tli«  night,  and  early  in  the  morning  look  4  oz.  of  oil  of  turpen- 
tine in  a  pint  of  gruel.  Ho  was  kept  faaiing  for  two  or  three 
hours  afterwards,  and  then  fed  sparingly  with  bran  mashea  and 
warm  water  during  the  day.  This  previous  fasting  appears  to 
tne  necessarv  lo  the  success  of  the  medicines;  for,  in  tnia  case, 
il  seems  probable  that  some  part  of  the  turpentine  is  absorbed 
from  the  empty  stomach  and  bowels,  eo  llist  the  worms  are 
attacked  both  in  the  bowels  and  through  the  medium  of  the 
blood.  The  celebrated  rcmody  of  M.  Chabert  for  worms  is 
said  lo  consist  principally  of  empyreumatic  animal  oil.  A  mix- 
ture of  olive  oil.  tar,  and  oil  of  turpentine  has  been  found  ad- 
vania^^us  in  the  rot  in  sheep;  a  tiiseasc  occasioned  by  worms 
in  the  liver,  nAtaedJitikes. 

From  iIm?  experiments  of  Profi^ssors  Tlcdcmann  and  Gmelin, 
lately  published,  it  apjiears  probable  that  thi*  mixture,  whicJi  is 
to  be  given  after  a  niiiht's  fasting,  is  absorbed  from  the  emply 
stomach  and  bowels,  and  conveyed  innnediately  to  the  ducts  of 
the  liver,  where  il  quickly  destroys  the  fluk<'s.  It  is  not  un- 
likely. I  think,  that  a  similar  mixture  would  be  found  a  good 
TCfmifuge  in  horses. 

[Thv  great  error  in  the  exhibition  of  vermifuge  medicine  is 
in  not  continuing  its  use  fur  a  suflicient  length  of  lime.  When 
we  consider  the  vast  amount  of  surface  affbnUii  by  th*^  intestines, 
and  thnt  worms  may  be  attacliod  to  a  groat  portion  uf  it.  It  may 
readily  be  conci-ived  that  a  few  doses  of  medicine  must  com- 
pletely fail  in  eradicating  the  greater  portion  of  them.  Another 
error  consists  in  not  sufEciently  attending  to  the  reKtorntion  of 
the  coaU  of  the  inte»tin<-s  and  the  system  generally  to  u  healthy 
■talc;  and  thus,  though  some  worms  may  he  removed,  yet  the 
■ysieni  is  lefl  in  a  favoumblc  state  for  the  production  of  more. 

The  following  mediciiH-it  have  been  foun<l  by  the  Kditor  ex- 
ceedingly useful,  not  only  in  dcittroying  the  worms,  but  in  re- 
storing the  condition  of  the  iinimn) :  — '

DISEASES   OF   TBC    LtVER. 


I 


Tbu  omn  is  not  so  often  diseased  in  the  hors«  as  in  the  hntnan 
body.  I  have,  however,  in  examining  Itorscs  after  death,  »ee« 
it  diseased  in  a  considerable  degree.  From  ihc  contparativc 
simplicity  of  its  structure,  and  lire  abscwc  of  a  gall-bladder,  It  i» 
seldom  affected  with  jaundice.  The  Uvcr  itself|  Iwwever,  is 
Boraelime«  found  condensed,  thickened,  or  liardcned ;  but  more 
fretjuently  distended,  ten<lcr,  and  easily  broken.  So  Irnder, 
or  rotten,  as  it  is  commonly  termed,  does  it  become,  that  it 
sometimes  hursts,  or  »  niplnrc^l,  and  the  horse  dies  by  an 
efTuftion  of  blood  into  the  cavity  of  the  abdomen. 

[Diseaseft  of  the  liver  are  much  more  frequent  in  tlie  summer 
than  in  the  winter,  and  particularly  in  very  Itot  weather.  At 
thia  season,  inflammation  of  the  liver  has  oflen  been  connected 
will)  the  epidemic  inl1ii>.-n/.a,  which  it  lias  rendered  far  mort 
obttinate  and  daii^iTixis. 

The  <yuiM.-a  of  ilii-»f  diieaxe*  are,  i:i  addition  to  the  predis- 
pmiiion  of  the  itnimal  to  have  the  liver  aiTccted  in  preference  to 
other  parui,  a  ri^un<)aiicy  of  blood  in  tlie  system,  by  which  loo 
much  bluocl  is  ient  to  the  liver  ;  too  nutritious  feeding ;  want  of 
cxcrcito ;  over-4>xeriiun  when  tin-  horse  is  in  this  unfit  state ;  and 
long  eonliiuiance  of  un  unhealthy  slate  of  tlic  excretions,  and 
want  of  pro|>er  physic'. 

Tlie  di.ieascH  of  ilie  liver  in  tlio  liorw  are,  perhaps,  more 
obaeure  than  those  of  any  other  {Niru  It  is  here  tliat  we  requin;

rounded witli  difficulty  nnd  ubscurity.  Diseases  uC  tlie  livvr  not 
oiilv  exikt  M  primnrv  nnd  iiide[)eiident  atTcctiotiK,  hut  ihvy  orv 
atill  raore  frequeiilly  connected  with  other  CQinplniiits,  tlic 
symptoms  of  whieli  are  thereby  rendered  more  obscure,  and  lliu 
cases  far  more  dangerous.  The  liter  is  subject  to  inflanininiion 
of  two  kinds,  acute  and  chronic. 

The  M^mpttimt  of  the  former,  at  first,  are  mild,  us  well  as 
obscure,  and  some  days  usually  transpire  before  any  tr<^t* 
ment  is  put  in  practice.  The  symptoms,  however,  toon 
afterwards  become  iiilcnBo,  the  mouth  feels  hot,  the  extn-mitiea 
cold,  the  mtmbranc  of  the  eyelids  is  higlily  injected,  and 
often  appears  of  a  deep  orange  colour.  At  first  the  pube 
is  not  so  rapid  as  the  other  symptoms  are  severe;  but  it  gra- 
dually increases,  becoming  scvtiiiy  or  eighty  in  a  minute^  and 
is  often  soft  and  vacillating.  TIh-  tiorsc  refuses  his  food,  looks 
round  at  his  sides,  lii«  down  and  gets  up  frequently.  The 
n-KpifHiion  is  somewhat  di»turbc<l;  but  this  symptom  cannot 
be  ik-peiided  on,  for  somelinim  it  is  tranquil,  at  others  greatly 
•eccJerBtcd;  there  is  usuully  a  tenderne»  evinced  on  pressing 
tboside*,  panicularly  the  right  side,  but  can*  must  be  taken  to 
distinguish  tliis  from  tin;  usual  flinching  evinced  when  the  skin 
is  pre»«'d  agatntt  die  Ijorders  of  the  rilw.  The  fieees  are  tiard, 
evaeuaicd  in  small  quantities,  frequently  of  a  diirk  colour,  and 
sometime*  covered  with  mucus.  Occusioiuilly  they  ar<:  fa-tid, 
and  sometimes  there  is  diarrhcea.  In  son>e  cases  tliere  is  a 
stilTnesft  in  moving,  particularly  of  lite  liind  quarters. 

The  Treatment  must  not  be  so  active  as  that  in  pneumonia, 
and  bleeding,  in  particular,  must  be  cautious  and  moderate;  for 
very  severe  blooclleltings  are  prejudicial  in  this  disease.  From 
three  to  five  quarts  of  blood  may  be  taken,  according  to  the 
sixe  and  condition  of  the  animal,  and  again  when  the  pulse 
apjiean  to  indicate  its  repel  it  ion.  Mr.  Cupiss,  who  has  written 
a  very  ui«eful  es^y  on  lite  diseases  of  the  liver  *,  recommends 
the  tullowing  medicine: — Aloes  1  lo  2  drs.,  and  carbonate 
of  poiash  sJrs.,  dissolved  in  hot  water,  and  then  well  agitated 
with  1*2  ounces  of  castor  or  linsLvd  oil;  to  be  repeiited  every 
twelve  lioiirs  until  the  bowels  arc  moderiUeiy  relieved,  bock- 
raking  nnd  clyslering  Ix-iug  likewise  practiced.  This  efK-ct  ob- 
tained, he  advises  the  following  to  be  adminixlered  t.-very  twenty- 
four  hours ;  —  carbuimte  of  potash  S  drs.,  powdered  resin  G  drs., 
with  linircd  nH-al  sufficient  to  suspend  the  resin  in  wunn 
water.  'I1ie  xmIcs  and  atidoinen  should  be  extensively  bli»tei^-d, 
and  frrvhitheepMkin.i  npplied  over  the  body.  Although  the  plan 
pursued  by  Mr.  Cupids  is,  in  many  rcsjK-cls,  very  judicious,  it

whicii  medicines  will  be  fou»(f  particularly  xtaeUii  in  Pie  tblW-

of  ttvc  former,  and  one  lo  two  scrupli'«  of  ibc  latter.  Mr. 
S.  Brown,  in  an  excellent  essay  on  tlw  subject,  reconimendi, 
wlien  there  arc  ^vmptonisof  pain,  linclurc  of  opium  in  moderaic 
doM'M,  wiili  an  alkali  and  linseed  oil,  in  order  to  allay  the  irri- 
tation of  (he  mucous  coat  of  the  bowel*;  after  winch  he  »i- 
niiiii«ter<  calomel  and  opium,  two  thirds  of  the  former,  and 
one  of  the  latter ;  the  latter  to  retain  llic  former  in  tlie  system. 
When  pwrgins  is  prew-nt,  a  pn-aler  quantity  of  opium  shoaldbe 
given.  In  the  Inlter  stage*,  wlwn  jjreat  tieliilily  exi^ta,  he  giv« 
tonics  and  stimulants,  with  small  doses  of  uitre  and  tartarual 
anliniony. 

Chrvnie  infiamwatiott  of  the  Kvar  may  either  follow  or  pre- 
cede an  acute  attack,  or  it  may  exist  independent  of  it.  The 
sytiiptoms  tat;  —  pnlse  ioiinrwhat  nuickened,  loss  of  appetili% 
hid»-bound,  nnd  siaring  coat,  and  dult  and  dispirited  appearance. 
The  fieces  haid,  and  of  a  pale  colour.  The  treatment  luiul 
be  similar  in  its  nature  to  that  recommended  for  the  «^ 
attack,  the  dose,  however,  being  more  moderate.  Bleeding  ■ 
be  avoided  in  the  majority  of  cases,  unless,  indeed,  the  symptoms 
urgently  demand  it. 

Mr.  Cupiss  observes,  "  In  post-mortem  examinations,  the 
liver  is  sometimes  found  lo  l>e  atlaclH-d  10  the  stirmtinding 
parts,  and  is  generally  inierg|)erse<l  more  or  less  thickly  wila 
white  scirrhous  patches.  After  actiie  lie|>atitis,  1  have  (bund 
the  liver  quite  yellow,  and  weak  in  its  tiodurc." 

Mr.  Cupiss  (k'scribes  three  other  aflcciioiis  of  the  liver, 
which  lie  tern)s  tmnithtral  enliiry^mrnt,  <}i-caifnl  structure,  and  («- 
liriiltlii/  trcreliiiii;  and,  without  iU-kiiowlt.'dj;ing  the  entirecorrect- 
■lexs  of  his  ilivixionii,  believing  that  decayed  structure  U  very  fre- 
fjuenlly  tlie  consequence  of  an  inflammatory  action,  yet,  as  hts 
observations  are  full  of  nraciical  utility,  we  cannot  do  better 
tlian  quote  them  at  length ;  — 

"  Unnatural  enlargement  of  the  liver  sometimes  take*  place. 
It  is  Hwullcn  to  two  or  ihi-ee  limes  its  natural  siice.  It  prenentt 
an  apjK'snince  of  general  congestion  ;  it  becomes  gradually  filled 
witll  a  black  bloody  fluiil.  The  progress  of  this  variety  of  liver 
disMM  is  uncertain,  generally  slow,  and  almost  invariably  tatol." 

Tlic  symptoms  arc,  an  enlarged  and  tense  abdomen;  the 
bowels  Homct!m<.-s  constipated,  at  other  times  relaxed ;  there  is 
■omMimeM  coii:U(U^rable  thint;  the  pulse  is  accclvrati'd  to  100  or 
more,  loud  and  thumping,  and  easily  mistaken  for  a  primary 
afR-ctiou  of  tlie  hearl. 

The  most  efrcclual  treatment  will  consist  in  a  cautious 
administration    of  laxatives,   accompauicd    by   diuretics    and

also,  a  previous  altered  state  of  tlu-  \'m-r  produees  violent 
purging  from  the  admin iMratioti  of  the  smallest  doses  of  nau-

surfeit,  hidebound,  inability  to  maintain  long  and   violent  ex- 
ertion,  laintiieaa   and    the   frequent   cvaeuation   of  pultaceotu 
fjecc*,  in  whicti  fragments  of  indigested  food  are  discoverablc- 
The  surest  indication  is  a  yeilou-ncs^  about  tlie  conjunctiva  tLOd 
the  inner  coat  of  the  montit  and  the  nwtrils.     'I'his  is  an  oc- 
casional  attendant   on    tlie   llim*    foregoing   varieties    of   ibr    _ 
<liM.'a»c;  but  ibcrc  is  no  insUiiico  of  diseased  itnicturc  without    I 
it.     It  is  not  prolmble  that  in  the  home  (his  yellowness  shoDld 
mritc  from  tlie  iil»or|)tion  of  any  aeeumulntcd  or  concrete  bile, 
M  in  (he  huinnn  xubjeci,  ou  account  of  the  direct  rommunics- 
tion  betu'c<.-ii  tlie  Ivvcr  nnd  the  duockiiuni  by  mi-anii  of  the  bile 
duct;  and  althoit^h  it  in  poiisiUte  to  Iw  cauaed  by  the  enlnr<^l    I 
liver  [>rc«»ing  upon  the  duct  or  the  eontraclion  of  the  liiict    ' 
tlaeir,  yet  I  am  more  disposed  to  attribute  it  to  an  inability  to 
■ecrete  good  bile  or  effect  a  wrli^t  »e|>araiion  of  it  from  tbe 
venous  blood,  or  properly  to  di^tMHe  of  tliat  which  U  M«rete(l. 
A  mass  of  iinpcrfc-ctly  formed  biliar\'  fluid  is  therefore  corrinl 
along  tti  the  eirculntory  stream,  and  the  discoloration  ta  apm^^ 
over  every  part  of  the  svstcin.     At  the  same  time,  in  defau^^^| 
a  sufficient  portion  of  efFcciive  bite,  ihc  food  passes  along,  n^^ 
etcape*  from  the  inteittinal  canal  very  impt^ectly  digested.  1 

1  he  treatment  of  tlii«  varil^y  of  di^-ased  liver  demands  much 
caution.  Ill  no  inxtana-  havi-  I  found  a  rapid  cure  {iracticahle. 
Experience,  iherefiuv,  dictate*  the  employnn-m  of  rtlcviive  bnl 
mild  nlterativos.     The  Iniicet  it  on  no  account  to  be  used. 

The  best  nllrmtive  that  1  know,  and  which  has  always  been, 
[o  a  greater  or  IcRs  degree,  useful,  or  ]  may  say,  effective  for  a 
time,  is  composed  of  aloct  I  to  2  drachms,  calomel  I  drachm,  resin 
(>  <lrachins,  made  into  a  ball  with  treacle  or  syrup.  'Diis  should 
be  given  every  third  or  fourth  day:  and  on  eiwh  of  tbe  io- 
terveiiing  days,  the  patient  should  have  sulphate  of  poMb 
3  drachms,  carbonate  of  potash  ii  drachms,  and  ginger  1  drBchm, 
with  liiisn'd  ntral  and  syrup  sulBcient  for  a  boll  of  proper  tile 
and  consistence. 

The  exercise  should  be  regular,  the  food  good,  and  not  Ins 
stimulating  than  the  patient  has  l>ecn  aecustomeil  to.  Ground 
corn,  pollard,  gn-en  food,  am)  thick  gruel,  wilt  alVurd  a  pleasant 
and  sufficient  variety.  In  the  course  of  a  forinighl  or  three 
weeks,  the  patient  usually  becomes  convalescentf  or.  at  least, 
lias  considerably  improved.  Ionics  may  tlten  be  administered, 
and  tbe  hone  is  apparently  resiorcMl  to  liealth.  All  ihta,  liow- 
crer,  b  too  ofWn  delusive.  From  iinusiuil  exertion  or  irregw- 
larity  of  feeding,  or  some  unknown  cause,  the  horse  relapses. 
The  former  mode  of  treatment  will  again  restore  him  ;  ondi 
perhaps,  a  third  time;   but  ultimately  he  dies.

be  surpritcd  m  ihp  abscttce  of  iInkc  morbid  It-sions  wlitcli  are 
usually  round  at  the  termination  of  f:ital  affcciionB  of  the  ab- 
dominal riiocra,  (bcre  bcin<;  no  congestion,  no  BUppiiration,  no 
inortifirntion.  TiacM  of  diseaw  are  obaervablf  iii  ibe  liver 
alone,  wbich  lioe  entirely  lo§t  its  natuial  bue,  and  bas  acquired 
a  yeliow-bruwn  colonr.  Sumelimes  it  i^  diminisbcd  in  size,  ami 
tlie  vv»»eU  uppvar  as  if  diejr  bad  lioen  vmptied  of  tbcir  oonleots, 
or  become  impcrviouf.  At  otlier  ttmrs  tnc  organisation  of  tlie 
liver  »  almost  (kslroyed,  and  (bcrc  remains  noilnng  but  a  soft 
pulpy  mass  fi-oin  wbicb  tbe  peritoneum  is  easily  separated. 

Tlie  liut  viiriity  of  diseased  liver  wliieli  1  linve  to  mention 
is  an  UHhftdlht/  trarlion,  generally  protlucrtl  by  cl re iim» lances 
favourable  to  iiicreaied  action  in  tbt*  (;bu)d,  lu  tbe  )u-ac  of 
summer,  and  alio  «tiddeti  cold ;  by  meniit  uf  vbicb  tbe  blood  U 
disproportionately  tbrown  on  tlie  inteniiil  organ*.  The  drinking 
of  unusual  cold  wutcr  at  this  Keason  of  the  year  will  produce  tbe 
••me  eflfcci.  Atioilier  c«uil-  ii  tbe  venous  blood  circulated 
through  the  liver  Ix-ing  itnprcgniiti'd  with  an  excess  of  carbon, 
in  consequence  of  wbtcb  the  bile  becomes  an  acid  and  irritating 
tubstance  both  to  ibe  liver  and  the  bowels. 

This  afTeclion  considerably  resembles  tbe  Englisli  cbolern  of 
the  human  subjecl,  and  is  characterised  by  violent  purging,  the 
evacuations  being  t>oth  fn^ueni  and  copious,  of  a  dark  colour, 
and  a  fetid  odour.  Tliere  ii>  a  continual  rumbling  of  tbe  in- 
testines, tlie  breathing  is  excessively  sfiort  and  hurried,  the  dfr- 
biliiy  is  very  great,  exceeding  that  produced  by  the  severeat 
race,  ihc  pulse  100  or  more,  and  in  tbe  worst  cases,  counted 
with  difficulty:  the  nostrils  expanded,  the  countenance  anxtoiM, 
and  the  extremities  cold,  and  the  body  covered  with  a  clammy 
sweat. 

With  such  excenive  action  as  this  going  on  in  tbe  horse,  which 
under  no  circumstances  can  endure  excessive  purgation,  tbe  Ri'st 
indication  of  cure  is  to  check  the  inordinate  diHcItarge,  and  to 
KUpport  the  constitution.  1  have  been  accustomed  to  adminiaier 
Iho  following  drink  every  four  or  mix  bourn:  ttarcbjib,,  port 
wine  I  pint,  laudanum  '2  ounce*.  In  moi^t  cuiteit,  three  of  these 
will  be  *uflicieni  to  n-sist  ibo  purging. 

Having  in  some  measure  quii-U-d  lliesystem,  I  have  cautiously 
given  oil  and  aloeoi  combined  with  un  opiate,  until  the  ex- 
cretions iitHumeil  a  mure  heiiltlty  character,  after  which  I  lisve 
bad  recourse  to  tlie  treatment  recommended  under  tlie  last 
variety  of  the  diw.>«se. 

Iti  tbv  ^Nutf-morteitt  api)eai-ances  tliere  is  the  same  absence  of 
any  comiderablv  le«ion  in  the  whole  of  the  intestinal  canal.  Th«

sometimes  exceeding  ten  gallons;  the  peritoneum  and  intcctiim 
of  a  faint  yellow  colour  or  quite  blanched.  The  Iivlt  presents 
a  ttimid  appearance;  some  |>oriiontt  of  the  [X'ritoneiil  coat  appear 
opaque,  and  fotir  or  five  time*  tlie  natural  ihickn<'«s ;  elsewhere 
one  or  more  rents  in  the  part  of  the  pcritom-al  co«t,  which  if  of 
the  usual  tenuity,  are  observed,  through  which  the  extntTamted 
hlood  has  escaped  from  liie  ramilicaiions  of  ihe  vetta  poriartim. 
Beneath  (he  peritonea)  membrane,  on  each  side  of  the  (Itisurrs, 
there  is  generally  some  dark  coagulated  blood.  Tlie  eo)o»r  of 
the  liver  is  various,  being  either  fawit,  light  yellow,  or  hrowni 
its  substance  is  exceedingly  brittle,  cim  easilv  be  torn  by  tlw

pounds.     Tlw  hepatic  duct  always  contains  bile. 

"  This  increas«l  si;«e  of  tlic  liver  is  occasioned  by  the  extrava- 
sation of  blood  into  the  substance,  and  under  the  peritoneal  coal, 
not  by  an  iticreate  of  the  natural  substance  of  tlie  organ.  If  d»e

seiisibility  of  the  I'etina  to  light,  until  the  eyes  become  com- 
pletely amaurotic.  It  is  a  remarkable  fact  that,  notwithstanding 
tlie  patient  may  rally  for  a  time  fi-ora  the  disease,  regain  his 
strength  and  condition,  and  return  lo  work,  I  have  never  seen 
nor  heard  of  a  single  instanceof  the  recovery  of  sight ;  allhougb, 
in  one  case,  the  Iior^c  worked  for  twelve  montlis  afterwards.

"  If  ihe  ha;ii>orrhage  be  beneath  the  iieritoneal  investment,  or

nish; and  about  the  third  day  of  such  improvement,  the  pre- 
viously blanched  conjunctiva  and  buccal  membranes  are  tinned

days,  red  ressela  arc  seen  ramifying  on  the  bilc-coIoured  mcm-

corresponding  improvement  taktM  place  in  the  other  symploma, 
the  pulse  becomi-s  fuller,  and  les«  frequent,  the  sighing  ceases, 
the  fiiz«  of  the  belly  diminishes,  the  horse  Ix-gins  to  feed,  and  lies 
down;  he  has,  however,  undergime  a  most  extraordinary  reduc-

perhaps  some  small  blood  vessel  l>ccome5  ruptured. 

I'lie  horse  should  be  rested,  bled,  and  physicked  ;  and  if  the 
rmptonis  are  very  severe,  the  same  treatment  should  be  em-

It  sometimes  Imppens,  however,  that  the  urine  t>ecomcs  foul 
and  stimulating  from  high  or  unwholesome  feeding.  In  (his 
case  tlie  bladder  will  contract  upon  a  small  quantity  of  urine, 
and  the  urine  may  be  rather  hign-coloured  like  beer,  or  turbid 
like  whey,  and  the  horse  may  appear  to  strain  a  little  in  r()i<liiig 
it ;  but  this  is  very  diflerent  from  those  distressing  nymptoms 
which  attend  inflammation  of  the  kidneys,  nor  is  it  accompanied 
vith  lots  of  appetite,  or  any  degree  of  fever,  which  is  always 
present  in  inflammaiion  of  the  kidneys.  When  the  urine  he- 
mes thus  stimulating,  sonic  cold  mashes,  with  a  little  nitre, 
«y  be  givcji,  or  what  is  still  belter,  perliaps,  wrac  grass,  vetches, 
or  lucerne.  If  the  horse  is  at  all  costive,  a  clyster  should  be 
thrown  up.  An  infusion  of  linseed  is  a  good  drink  for  a  horse 
when  the  iirinc  is  in  this  stale.     There  are  other  diseases  of  the

independent  affection.  It  is,  I  think,  more  frequent  in  tJie 
jnare  than  the  horse,  and  it  has  been  produced  by  injecting 
acrid  substances  into  the  bladder  with  n  view  to  promote  Uie 
disposition  to  copulate.  Some  casvs  of  this  kind  were  related 
by  tbc  late  ProfcESor  Colemnn.  It  may  also  be  produced  by 
irritating  medicines,  such  as  canthuridt^f  gin.-n  in  liie  usu^ 
way. 

Dte  tytnptom*  of  this  dieejuc  arc  cnsily  recognised.  There  is 
considerable  fever  and  (juickiins  of  pulse,  and  ti  great  deal  of 
pain  exliibited,  tlic  animal  looking  round  to  bis  quarters,  and 
lying  down  and  getting  up  frrquenlly.  Attention  is  directed  to 
the  seat  of  disease  by  tbc  unremitting  attempts  at  stulitig  evinced: 
DO  sooner  do  u  tew  drops  of  urine  enter  the  bioddt-r  than  it  is 
forcibly  ejccti'd  with  a  spJismocHc  effort.  The  orgiins  of  genera-

eusc  is  more  dang(.-rou:4  (ban  inllamination  of  tlie  kidneys,  and 

^uiilew  relief  be  ubiained,  death  supervenes  in  a  few  day*. 

^K  A  i>iut-tnortem  examination  exhibits  the  mucous  inciitbraiie  of 
ine  bladder  intensely  Iiitlamed,  and  some  portion  of  It  fR-rjuently 
in  a  aliile  of  ulceration. 

The  trralvirnl  consists  of  copious  venesection,  repeated  in  six 
or  eigbl  hours  if  required.  Itackraking  and  the  frequent  ad- 
miimtration  of  injections,  imd  niuciloginuuH  (luIdK,  such  as  linseed 
lea  or  infiuiun  of  gum  antbic,  should  be  carefully  and  slowly 
injected  into  tlie  bladder;  and  it  wuuld  be  serviceable  if  B 
watery  infusion  of  opium  were  injected  at  the  snme  time,  A 
drachm  of  powdered  opium  infused  in  half  a  pint  of  hot  water, 
and  afterwards  strained,  wdl  serve  for  several  applications.  Oily 
laxatives  should  be  given  bo  as  to  I'clax  the  bowels  without 
purging  them;  and  half  a  drachm  of  opium,  with  one  drachm 
of  lariarised  antimony,  may  be  given  three  times  a  day-  I'lenty 
of  linseed  lea  should  he  given  voluntarily,  if  possible;  but  if  not,

jj^  [_Ihtention  vf  Urine 

^klore  fre<)uently  occurs  as  a  troublesome  attendant  on  other 
diseases  than  as  an  independent  affi-ction.  In  those  gencnil  and 
complicated  inflammatory  diseases,  understood  under  the  term 
diHl,  a  retention  of  urine  is  frctjucntly  present.  In  colic^  too, 
there  is  frequently  an  Inability  to  stale,  notwithstanding  frequent 
cfToris  to  do  so,  but  this  Is  owing  to  sympathy  with  the  »pa)tm 
of  the  bowels ;  for  when  the  latter  arc  relieved,  the  horse  stales 
wiihont  difRculty.  From  neeing  these  abortive  attempts  at 
staling,  grooms  almost  invariably  xay,  in  cases  of  colic,  that

up  the  ri-ctum  we  tind  (he  bladder  very  much  diatvnded  wtilt 
urine,  which  iLwures  us  of  the  nature  of  the  diseaMS  which  tlir 
mere  frequent  attempts  at  staling  would  alone  be  insufficient  to 
decide 

Trtalfund.  —  If  the  patient  be  a  mare  we  sliould,  witlioui 
liesilalion,  evacuate  the  bladder  by  means  of  a  flexible  tube, 
culled  a  cBthcIer.  The  method  of  doing  this,  however,  rcauirM 
a  little  tact.  The  instrument  slmuid  he  introduced  at  ihr  lower 
part  of  the  vuiiea,  under  the  fore-finger  of  llie  right  himd,  wjiich 
Bcrves  es  its  guide.  A  few  inches  within  the  entrance  t)ic  fold  of 
membrane  is  fell  which  covers  the  parage  to  die  bladtlvr ;  this 
membrane,  being  railed  by  the  back  of  the  foro-linger,  tlio  tube 
is  readily  puslMxl  onwards  into  the  bladder. 

If,  however,  (he  patient  be  a  male,  we  must  first  endeavour  to 
OAitUl  nature  by  boeKraking  and  rlystcrini;,  and  perhaps  foineot- 
ing  the  a)KlumL-n,  and  occasionally  pressing  the  Ikand  on  ibe 
bladder.  If,  however,  wc  do  not  succe>ed'  in  the  course  of  lialf 
an  hour,  and  the  bladder  is  very  full,  we  should  proceed  to  pass 
the  catheter,  which  is  a  hollow  flexible  tube,  about  a  yard  in 
length,  having  a  whalebone  stilet  within,  which  can  be  with- 
drawn,  as  we  please,  front  its  cavity. 

An  opportunity  should  be  enibrnci-<l  when  ttx-  penis  ia  pro- 
trudi-<l  from  the  nheuth,  otherwise  it  muy  be  excvt»lingly  difficult 
to  rciurh  and  retain  it.  It  should  be  then  firmly  gra^>ed  with 
ihe  left  hand,  drawn  out  to  its  full  extent,  and  with  the  right 
hand  the  tulie,  well  oiled,  >hoitld  be  carefully  fortx-tl  up  the 
tireihra  until  it  enten  the  hUdder.  It  may  readily  be  felt 
in  ii»  course,  at  the  perineum,  just  under  the  anus.  Having 
entered  the  bluilder,  ilie  whalebone  stilet  aliould  be  withdrawn, 
■lid  the  urine  will  tlien  flow. 

After  (he  operation  the  symnioms  usually  disajipear,  and  llu 
animal  feeds.     If  Uiere  is  much  gei>eral  irritation,  it  is  woll  to 
[  bleed  either  before  or  aftei*  the  operation ;  and  if  any  other 
syinptonts  appear,  tlie  case  must  be  treated  accordingly. 

If  I'elief  be  not  iluia  obtained,  the  urgency  of  the  symptoms 
will  increo-ie,  and  the  bladder  may  burst,  and  death,  of  course, 
ensue.

[Profewor  Ciintrd,  of  the  French  school,  htu  written  im  able 
invmuir  on  tlie  Mubject  of  vnical  calculi.  He  ndviite>  the  opera- 
tion  lo  be  perlbrmed  with  the  patient,  wlietlier  male  or  female, 
in  a  standing  posture,  and  properly  secured,  and  directs  the 
incision  in  the  male  to  be  made  in  an  oblique  direction.  "  In 
the  feinale,"  be  says,  "  the  stone  may  be  extracted  by  the  dila- 
tion of  the  urethra  by  mechanical  means,  aided  by  relaxing 
injections  and  fomentations;  cystotomy  is  only  to  be  resorted 
to  when  these  fail."  In  this  casi-,  lithotomy  consiati  simply  in 
laying  open  t)»e  urethra  itlong  its  median  line  and  from  behind 
forwards :  it  te  to  be  perfornu-d  with  a  bistoury  directed  by  one 
of  the  finger*  of  the  left  Itiiiid.  In  ihi:t  manner,  M.  Dufils, 
V.S.,  at  Kourdenux,  in  1H21,  extrncted  a  stone  from  a  mare, 
witicb  wa*  linlgud  in  {Mirt  in  the  meatus  urinarjui,  whereby  *\n; 
who  was  before  tlw  subject  of  frequent  colics,  became  at  once 
restored  to  easei  and  speedily  afterwards  to  health.  In  the 
oeiure  of  the  stone  was  found  an  almond,  forming  its  nucleus. 
At  il)e  time  it  was  shown  to  us,  M.  Dufits  assured  us  that  it 
liad  lost  much  of  its  weight  and  volume,  proving  thcrcljy  that 
these  calculi  contain  a  large  proportion  of  lluld,  tlic  evaporation 
of  which  evidently  brings  on  this  diminution.

kiiouu  in  regimeiils  of  cavalry,  where  it  is  too  common. 

During  the  time  that  horr<ii  arc  breaking,  more  particularly,

towards  the  clicst.  The  bit  iiwa  bears  on  the  under  jaw  between 
the  tush  and  t)>e  lirst  grinder.  Tlie  boue  in  Una  part  being 
thinly  covered  with  gum,  is  often  bruised  and  inflamed ;  ana 
being  neglected,  or  mther  the  pres'^ure  being  still  continued,  it 
becomes  curious,  uiid  a  troublesome  sore  or  situis  is  the  conso- 
quenoc.  and  occasionally  a  portion  of  the  bone  is  deprived  of 
nourishment  and  exfoliates.  This  sore,  in  feeding,  becomes 
filled  with  masticated  hay,  which,  being  discovered,  is  supposed 
(O  be  the  eattsc  of  the  sort';  and  as  common  hay  cannot  be  sup- 
posed to  l>e  oa|>able  of  Mich  an  effect,  it  is  attributed  to  what  (Im 
grooms  term  M)uirrel-tail  grass,  that  h,  wild  barley.  This 
severe  bitting,  thuuj^b  not  always  m-cessary,  is  llie  most  etlecttml 
method  of  subduing  the  teinp«>r  nf  a  xiiiliburii  hone  that  can  be 
B(lopt<'d.  Jl  will  more  elVectiially  cure  restivene&s  tlian  any 
punUhinent  that  can  be  devised,  and  if  properly  conducted,  will 
make  a  mouth,  or  rather  a  temper,  whatever  die  rider  wisJiea  it 
lo  be;  lor  what  is  called  softening  or  making  the  mouth  is  in 
fact  softening  or  making  the  temper.  There  is  great  danger, 
however,  of  altumpiing  to  make  the  mouth  at  the  time  of  riding, 
by  means  of  a  running  rein ;  for  if  h«  is  a  stubborn  or  runaway 
horse,  there  is  great  danger  of  throwing  him  down,  and  in  the 
most  dangerous  nuinner  that  can  be.  I'or,  if  ho  is  determined 
to  run  away,  and  the  ri<ler  endvuvotir«  lo  prevent  him  by  a

I  there  is  re«8on  to  aj^irebend  exfoliation,  the  best  plan  i«  tQ 
hasten  the  separation  of  the  bone  by  the  applicntion  of  cauitiev 
fltieh  as  diUili^)  muriatic  acid  on  a  little  tow.  After  the  s^iara- 
lion  of  the  itcad  hone,  the  part  will  soon  gel  well.  It  may 
afterwards  l>e  dressed  with  lincliire  of  myrrh. 

If  the  horse  is  u»d  during  the  iirogn'fdi  of  the  cure,  a  niaffle

I  have  known  a  similar  ulcer  form  under  the  loogne,  accoi»> 
panied  with  considerable  inflammation  and  swelling  of  tlic 
modili,  so  as  to  prevent  feeding  for  several  days.  A  portion  of 
iIh'  lower  jaw-bone  exfoliated,  after  which  the  part  soon  got  »i'1l. 

Sometimes,  during  dentition  or  teething,  the  whole  mouth 
becomes  inflamed  and  sore,  and  this  state  generally  extends  lo 
the  stomach,  causing  loss  of  appetite.  In  such  cases  the  excrfr 
tory  ducts  of  the  sublingual  glands  being  rather  swollen,  liave 
been  mistaken  for  a  disease,  and  cut  on.  'Hk*  only  tiling  ne- 
cessary in  such  cases  is  to  keep  the  horse  on  bran  muslies  a  short 
time.  No  me<iicine  is  necessary,  and  bleeding  is  Ktidered  un- 
necesiarj'  by  the  iosa  of  appetite, 

In  giving  balls  improjierly,  the  under  ]>art  of  the  tongue  is 
of^en  laeeraied,  which  renders  feeding  painful,  and  makes  the 
horse  slaver  and  froili  at  the  mouth.  'HiU  may  be  cured  by  a 
solution  of  nliini,  which  iihoutd  be  thrown  in  with  a  syriiigfb 
We  sometimes  find  the  firsit  grimier  so  une<pudly  worn,  as  tO

act^uiring  a  morbid  irritability,  which  causes  it  to  contract  upon 
the  approach  of  the  food,  and  return  it  into  iIk  noetrils,  or  uito 
the  mouth,  where  it  is  oflen  re-mast icaled,  and  at  length  thrown 
out  into  ilie  manger  like  a  quid  of  tobacco.f  Such  horses  luvo 
been  named  qitidden  by  deuers,  and  are  considered  of  little  or 
no  value:  such  cases  are  often  incurable,  and  Bometimc*  >a 
because  not  understood.  Were  the  horse,  in  the  curly  stage 
of  the  diwoae,  kept  a  few  wveks  od  gruel  and  bran-maslic^  and 
then  turned  to  grass,  the  muecles  of  deglutition  would  sometimes 
gradually  recover  llteir  lost  power. 

I  have  lately  met  with  a  case,  in  a  man?,  where  bolli  swallow 
ing  and  breathing  were  impeded  by  idccrntton  of  the  pharynx, 
or  upper  part  of  tl>e  ccsoplmgus  or  gullet,  produced  protiably  by

occasioned  caufol  rnti^bing,  and  some  of  the  food  to  be  thrown 
into  (he  noitriU,  and  some  into  tlte  larynx,  wtiere  it  produced  a 
grvsi  deal  of  pain  and  difficulty  in  breathing,  so  much  w  that 
llie^'  were  about  to  destroy  the  animal.  But  I  afforded  great 
relief  by  making  an  opening  in  the  windpipe,  and  passing  a 
surgeon's  probiing  into  the  opening,  and  up  ihrough  the  larynx, 
and  then  quickly  withdrawing  it.  1  then  passed  it  up  again, 
and  wttlidrew  it  a  second  time,  in  order  to  remove  completely,

for  balU,  when  properly  niade  and  skilfully  gifen,  will  pass  into

them  tlie  lull  waa  wrapped  in  brown  paper;  and  in  one  the  ball 
was  as  hard  as  sione,  and  had  destroyed  the  internal  membrane 
of  the  (esophagus.  These  cases  prove  the  necessity  of  giving 
bail*  when  recently  made,  and  not  too  hard  or  large.  I'o  avoid 
tliin  evil,  in  giving  a  ball  we  should  never  be  satisfied  until  we 
str  it  pass  down  the  grester  mrt  of  the  ixsophagus.

hard,  anil  covered  with  mucus ;  but  the  skin  and  legs  are  warm, 
and  the  horse  prefers  a  siatidin^^  posture,  unless  the  joints  are

le«  severity,  though  of  greater  obstinacy.  It  atfecu  the  muscular 
and  tendinous  fibres,  tTie  ligaments,  tn«  joints,  and  even  the

for  weeks  and  months,  and  sometimes  prove*  inciimble.  In 
the  joints  it  is  sometimes  attended  wiili  swelling,  hcul,  and 
tenderness;  and,  in  some  cases  of  rhcumiitic  kimnH-Hs,  tht-re  is 
no  swelling  or  other  appearance  to  indicate  its  situation;  and 
we  can  only  infer  that  it  is  rheumatic  by  its  going  olT  uder

CHAP.  XLI. 

EPIZOOTIC   OR    EPIDEMIC   DISEASES.* 

[From  time  to  time,  in  all  ages  of  the  world,  diseases  of  nn 
epidemic,  or  rather  epizootic  character,  have  appeared,  and 
destroyed  vast  numberB  of  horses  and  cattle. 

It  will  be  unnecessary  to  go  back  to  times  of  remote  an- 
tiquity, although  numerous  are  the  instances  that  might  be 
adduced  from  classical  authors  of  the  most  severe  epizootics 
having  extensively  prevailed;  and  in  all  probability,  from  the 
absence  of  draining,  and  the  marshy  and  unhealthy  situations 
of  many  parts  of  the  then  civilised  world,  these  maladies  were 
more  virulent  in  their  nature,  and  more  fatal  in  their  conse- 
quences, than  those  which  have  prevailed  in  modern  times. 

"  In  1714,"  says  Mr.  Youatt  in  his  Lectures,  "  a  malignant 
epidemic  was  imported  from  the  Continent,  and  in  the  course  of 
a  few  months  destroyed  70,000  head  of  cattle.  In  horses,  the 
disease  was  almost  uniformly  ushered  in  by  inflammation  of  the 
mucous  membrane  of  the  respiratory  passage,  but  soon  involving 
other  portions;  and  then  ensued  diarrhoea,  which  no  art  could 
arrest.  The  fever,  acute  at  first,  soon  passed  over,  and  was 
succeeded  by  great  prostration  of  strength.  The  inflammation 
now  spread  to  the  cellular  texture,  and  there  was  a  peculiar 
disposition  to  the  formation  of  phlegmonous  tumours;  some- 
times there  were  pustular  eruptions,  but  oflencr  deep-seated 
tumours,  rapidly  proceeding  to  suppuration.  Connected  with 
this  was  a  strong  tendency  to  mortification ;  and  unless  the 
animal  was  relieved  by  some  critical  flux  or  evacuation,  malig- 
nant ^phus  was  established,  and  the  horse  speedily  sunk." 

Our  next  account  refers  to  two  epidemics  related  by  Gibson, 
one  in  1 732,  the  other  two  years  subsequent ;  the  first  occurring 
towards  the  &I1  of  the  year,  the  second  towards  the  spring  or 
summer.  The  former  appears  to  have  been  precisely  similar  to 
our  epidemic  catarrh,  and  attended  with  considerable  nasal  dis- 
charge, and  unaccompanied  with  danger ;  whilst  the  latter  dis- 
ease was  more  fatal  in  its  effects,  was  accompanied  with  a  burning 
fever,  soreness  of  the  skin,  loss  of  appetite,  costive  bowels,  and 
followed  by  swelled  legs.  We  recognise  In  the  last  nearly  all  the 
symptoms  of  ittfiuenxa,  particularly  as  it  presents  itself  to  our 
notice  in  warm  weather.     Gibson  treated  both  these  diseases  by 

■  E;ndemic  literally  signiHcs  b  disease  aCtacking  numbers  of  men;  while 
cpiiootic  refers  to  cattle,  and  is  therefore  Hiorc  correct  in  this  ploce.  They 
arc  each  derived  from  tnro  Greek  wortla.

We  next  avail  oursdvn  of  Mr.  Youalt's  admirable  Lectures, 
in  quoting  an  account  of  an  epidemic  thai  prevailed  on  the

lo  hare  bad  reierence  to  a  poisonoua  and  improper  diet.  lu 
syntptoms  were  low  and  malignant,  its  progress  rapid,  and  uv- 

|jnination  usually  fatal.  In  1795,  we  find  that  a  (usraae  ra^cd 
in  Paris  and  its  vicinity,  attended,  as,  indeed,  almost  all  theK 
Continental  epizootics  appear  to  have  been,  witti  low  typltoid

IJetting  decidedly  injurious;  the  evacuations  were  livtid,  the 
debility  great,  and  death  usually  closed  the  »;ene.  In  1815, 
and  again  in   It^tiS,  we  appear  to  have  l>ad  a  fatal  epiKootic  in 

[this  country,  attended  witti  KwclUng*  aiKl  ulcerations  in  varioui 
pirts  but  we  regret  tlut  no  uutlwiitic  account  of  the**  di«eases

We  next  come  to  tite  pages  of  the  t'rtrrinarian,  and  And,  in 
the  first  volume,  a  pai>er  from  Mr.  Brown,  de«cribiiig  the  ep^ 
detnic  as  it  came  under  his  uolice  in  the  early  part  of  llie  year 
1&26.     In  some  measure  it  Aseinbled,  in  other  res]>ects  it  crntlly 

[differed  from  llie  induenza  of  1836.  It  hbs  accompanied  by 
complicated  inflammation,  diarrlraea,  and  considerable  debility. 
Mr.  Brown  found  that  an  aniiplilogislic  mode  of  treatment  ali> 
gctlier  failed,  but  a  Ionic  and  supporting  system  proved  gi-nerolly 
euccesaful. 

Mr,  GloBg  gives  an  account  of  an  epizootic  which  made  its 
appearance  in  the  rcginieiu  of  huxzars  under  his  care,  and 
proved  exceedingly  latul.  It  does  not  appear  lo  have  been 
influenza,  but  a  dueuse  of  typlwid  character,  presenting  from 

'ils  outset  tlte  greatest  debility;  forbidding  the  slightest  depiction, 
but  requiring  a  supporting  systetn  of  treatment.  Th«  latter 
cases  proved  succesitol ;  but  they  were  by  no  means  allendcd 

[  with  such  malignant  symptoms  as  characterised  the  earlier  ones- 
Id  diseases  presenting  such  analogj-  of  typhus  as  this  appears  lo

find  sitch  very  diHerent  ideas  arc  entertained  in  (he  minda  of 
Ibepublic  with  regard  to  this  disease. 

This  disease  prevailed  most  extensively  in  1836,  throughout 
all  parts  of  (he  kingdom.  NnrnerouK  nccounts  of  it  may  be 
found  ill  tile  Cfirrinarian  for  that  and  the  fnlluwing  year,  anil

11te  following  comprbea  tl»e  greater  portion  of  an  essay  written 
by  myself,  ana  reaa  before  iTie  members  of  the  Veterinary 
Medical  Aau)ciation  in  London,  [t  will  serve  to  show  ilic 
symptoms,  nature,  and  treatment  of  the  disease.

the  month  of  :Sepiember,  and  lias  continued  up  to  ()tu  pnicnt 
time.  My  fint  cases  were  f<.-w  bikI  isoIa(e<l,  but  (hey  gnidually 
become  more  numerous  and  more  accumulative,  'i'lie  symptoms 
were  very  similar  to  those  of  tlie  epizuoiie  of  1696,  at  any 
rate  suiBcieiilJy  so  to  justify  roe  in  denominating  it  the  same 
disease. 

"  Symptom*.  —  The  first  symptom  that  awakened  atteiit  ion  was 
the  sudden  Giilurc  of  the  appetite,  which  was  either  tuial  or  inr- 
tial ;  the  Iwrsfi  (K-rliaps,  niiglit  liave  ai>|K-ared  perfectly  well  in

J|uieketted,  varying,  however,  from  4'2  to  80,  lieing  suinetimcs 
uU  and  strong,  but  more  freciueiiily  soft  and  weak.  There 
was,  generally,  a  somewhat  dull  ajipearaiice  of  the  animal  at  first, 
although  nothing  to  what  afterwards  supervened ;  the  coat  woa

«iAaa  Msrinfft  and  when  bo.  the  attack  nsunlly  became  more 
wvere.  This  ^rin]>lom,  howeter,  was  (ar  from  being  )iiiivrr&»l. 
The  exiremilies  were  rarely  cold.  In  tl)c  course  of  six  or 
twelve  boiirs,  the  symptoms  became  more  ng^nivaied,  tbe  pu\st 
increased  in  frequency,  and  the  ai>[>i-titr  more  dimtni«hed,  and 
probably  tlie  legs  and  eyelids  were  contidcrably  awollra.  In 
some  casit  itic  mpiration  becamv  quickened,  and  in  othcrt 
tlieri!  wan  cougb  iind  nore  ibrnat,  but  in  the  majority  of  my 
IMtteiitit  ibere  wtu  no  broncbial  nffitiioa  whatever. 

"  In  a  few  in*taitce«,  tlie  disease  quickly  reached  its  acm£,  but, 
generally,  the  aymptoniii  iticreaued  in  severity  for  two  or  tiirrr 
davi,  when,  lu^uxwinj^  jiidic'toiis  treatment  had  been  em|ilo}'cd, 
they  gradually  (It^liiied,  and  at  length  totally  disappeared,  tlie 
animal  slowlv  regaining  his  former  health  and  spiriic. 

"  The  bowels,  generally  eiH-aking,  were  not  apparently  much 
deranged,  but  their  mucous  coat  was  particularly  susceptible  to 
the  action  of  aperient  medicines;  and  the  faeces  were  frequently 
enveh^ped  in  lliin  slimy  mucus,  and  oft<m  softer  than  tn  a  eute 
uf  health. 

"  In  Mine  cases  the  aflrciion  of  llie  eyes  was  w  violent  u  Id 
oct^on  lemjtorary  blindness ;  and  in  others  piteuinonin  was  pr^ 
aeni,  but  more  frcipii-nily  severe  bronchilii.  In  ntnny  |Mticnti 
the  a>demalous  swelling  ol'  tlu*  legs  was  enormous,  and  continued 
obstinate  when  the  other  symptoms  hod  abated;  but,  cominonlj>i 
in  propoi-tton  as  tite  legs  and  eyes  were  Hnuch  afTecicd,  the  ia- 
icrnal  viscera  were  free  from  disease,  and  vin  txrgd.  This  rale, 
however,  was  by  ito  means  universal,  for  in  several  iiatienti 
sievere  cephalic  and  tlionicic  symptoms  were  present  in  the  same 
subject,  and  at  the  same  time. 

"  When  an  animal  had  been  previously  sufTering  from  Mme 
chronic  disease,  such  oa  broken  wind  or  hepaiiicd  lungs,  the 
influenza  was  nearly  sure  to  light  up  afresh  the  embers  of 
former  fin*,  and  this  local  disease  generally  proved  Iroubli  ^ 
Hnd  olutiiiaie.  So,  likewise,  wln-n,  fnmi  the  idiosyncrasy  of  the 
niiimat,  an  organ  was  in  u  weak  an<l  susceptible  state,  itillamma- 
tion  in  that  jiart  was  <)iiickly  excited  by  the  general  fever  pre- 
sent in  the  system. 

*'  The  only  cases  that  1  have  loai  were  two,  with  previously  dis- 
eased lungs.  One  was  an  extremely  old  broken-winded  |iony 
that  sunk  rapidly  in  the  course  of  two  or  three  (hiys,  apparently 
more  from  the  weakness  induced  by  old  itge  and  broken  wind 
than  from  the  amount  of  n<'W  disease,  which  was  by  no  nimni 
great.  The  other  case  exhibited,  during  lift',  very  obtcurs 
symptoms,  which  were  in  some  measure  explaitied  by  tl>e  most 
complicated  inflammatory  appearances  after  death,  llie  Inii^ 
the  windpipe,  the  pleura,  the  pericardium,  and  tlie  heart  itselft 
as  well  as  tlie  liver,  exhibited  the  ravggea  of  the  moat  inleose 


IKFLCESZA.  209 

inflammatioii,  appnadiiiig  to  gangrene.  The  lungs,  as  &r  as 
could  be  judged,  iqipeared  to  have  been  antece^ntly  diaor- 
ganised.  This  aninial  lived  about  fifteen  days.  In  tbe  earlier 
stage  tbe  pube  was  strong  and  Aitli  and  be  was  bled  largely, 
more  so  than  any  of  my  other  patients. 

"  Tyeatmeiit.  —  Whenever  the  pulse  was  fnll  and  slrong,  I  ab- 
stracted blood,  and  always,  I  imagine,  with  tbe  best  effect.  In 
such  instances  I  observed  tbe  blood  slow  in  coagulating,  and 
invariably  presenting  a  buffy  coaL  I  took  great  care,  however, 
not  to  alntiact  too  large  a  quantity ;  and  I  found  I  could  produce 
the  desired  influence  by  half  the  quantity  which,  in  ordinary  in- 
flammatory afiectioDS,  it  would  be  necessary  to  take  away.  The 
amount  of  blood  withdrawn  was  always  determined  by  its  effect 
on  the  pulse,  taking  care,  as  soon  as  its  character  was  materially 
altered,  and  becoming  softer  and  less  perceptible,  to  pin  up  the 
orifice.  This  alteration  was  somelimes  produced  by  the  loss  of 
4  lbs.  of  blood,  oftener  by  6  lbs.,  occasionally  by  8  lbs.,  and  in  a 
few  instances  by  10  lbs.  In  two  or  three  cases  where  ibere  ap- 
peared to  be  severe  internal  inflammation,  I  repeated  the  blood- 
letting on  the  following  day,  and  in  one  case  in  the  same  day ; 
but,  as  a  general  mle,  even  in  cases  where  the  pulse  had  on  the 
following  day  r^ained  its  strength  and  fulness,  I  abstained 
from  a  second  bleeding,  trusting  to  medicine  and  the  progress 
of  the  disease  to  soften  the  pulse,  which  I  found  to  lake  place 
commonly  on  the  second  or  third  day. 

"  I  bad  recourse  to  local  venesection  still  more  frequently  than 
to  general  bleeding ;  indeed,  whenever  the  eyes  were  much  in- 
flamed, or  the  lids  swollen,  I  scarified  the  latter  with  a  lancet, 
and  opened  the  angular  veins,  which  course  of  procedure  1  found 
attended  with  the  best  results;  for  the  local  inflammation  gene- 
rally subsided  in  the  course  of  twelve  or  twenty-four  hours, 
whether  I  had  bled  generally  before  or  not. 

"  On  re&rring  to  about  6fty  cases,  I  find  that  in  twenty-three 
I  employed  general  bleeding,  in  the  remainder  I  did  not ;  but  in 
twenty-five  cases  I  bled  locally,  either  from  the  eyelids  and  veins, 
or  the  bars  of  the  mouth.  The  majority  of  these  were  cases  in 
which  I  had  not  bled  previously,  and  the  minority  belonged  to 
those  in  which  1  had  before  employed  venesection.  More  than 
one  half  of  the  horses  that  were  bled  generally  were  from  the 
same  stable,  principally  young  carthorses  that  had  been  recently 
purchased,  and  aflerwards  worked  very  hard.  They  had  also 
been  allowed  a  considerable  quantity  of  beans,  a  diet  to  which 
they  had  not  previously  been  accustomed. 

"  Among  these  horses  I  found  my  severest  cases  often  compli- 
cated with  pneumonia,  bronchitis,  and  other  visceral  derange- 
ment. In  them,  too,  the  blood  presented  a  thick  buffy  coat,  and 
the  pulse  was  strong  and  full.

'  My  uEual  treatment  in  the  way  of  medicineB  eoDBiBted  in  ai- 
ministering  the  following :  ^ 

Crotonoil 5  drops. 

Nitre 4  to  6dr. 

Tartarised  antimony 1  dr. 

Spirit  of  nitrous  ether  4  to  6  dr. 

Spirit  of  mindereruB 2  to  4  ok. 

Warm  water  sufficient  to  form  a  draught. 
"  Sometimes  4  drachma  of  bi-tartrate  of  potash  were  added  to 
the  above ;  and  wlien  tlic  head  appeared  much  aflected,  1  drBchm 
of  camphor.  This  draught  was  administered  generally  once, 
but  sometimes  twice  a  day,  the  croton  oil  being  omitted  after 
tlie  first  dose.  After  ilie  first  day,  in  by  far  the  greater  number 
of  cases,  2  drachms  of  centiau  wore  added  to  the  draught;  and 
after  the  second  or  third  day  a  ball  was  substituted  for' the 
draught,  consisting  of — 

Nitre  3  dr. 

Tartarised  antimony 1  dr. 

Gentian 2  dr. 

Pimento 1  dr. 

"  In  one  case  the  above  draught  produced  profuse  perspinuioo 
immediately  after,  and  each  time  it  was  administered.  Altbondi 
this  effect  may  be  principally  ascribed  to  the  idiosyncrasy  of  a* 
animal,  yet  it  proves  the  diaphoretic  properties  of  the  medicine^ 
although  tliis  may  not  generally  be  distinctly  perceptible. 

"  Counter  Irritation.  —  In  by  far  the  greater  number  of  caaei 
there  was  no  inflammation  of  the  air  passages;  but  whenever  it 
was  denoted,  I  blistered  the  throat,  the  course  of  the  windpipei 
and  the  breast,  or  inserted  setons  or  rowels,  as  the  particuur 
case  appeared  to  demand. 

"  Such  is  a  brief,  but  I  trust  a  succinct  account,  of  the  t^Ga^ 
nient  I  have  found  successful,  not  only  in  conquering  the  dii- 
ease,  but  in  restoring  the  health  and  strength  in  a  short  space 
of  time.  Although  the  majority  of  cases  were  not  dangerous 
yet  many  of  them  were  so ;  and  it  is  notoriously  the  fact,  that  t 
groat  number  of  horses  have  died  from  the  disease  in  varioui 
places.  Indeed,  in  the  establishment  to  wliich  I  have  referred) 
Uiroc  horses  died  from  it  under  the  care  of  another  person,  not 
a  member  of  the  College ;  and  in  several  instances  where  honei 
have  been  treated  by  the  owners,  although  the  case  was  not 
dangerous,  they  recovered  but  slowly,  and  with  great  loss  of 
condition. 

"  General  Remauks. —  I  have  found  in  the  present  ^idemic 
a  greater  disposition  to  cedematous  swelling  of  the  extremilie* 
and  sheath  than  in  that  of  1630  ;  and  so  obstinate,  occasionally, 
wore  those  enlargements,  that  they  were  reduced  with  mndi

difficulty,  and  only  after  the  frequent  and  continued  employ- 
ment of  diuretics,  and  the  insertion  of  eetons  in  the  thighs. 
There  likewise  appeared  to  be  throughout  the  attack  a  capa- 
bility  of  taking  large  and  repeated  doses  of  diuretic  agents  with- 
out exciting  the  kidneys  in  any  great  degree.  At  least  double 
the  quantity  could  be  given,  and  with  no  greater  action  than 
half  the  quantity  in  a  state  of  health. 

"  In  one  place  where  I  attended,  the  prevailing  epizootic  was 
raging  amongst  sheep,  and  at  another  place  amongst  cattle; 
but  the  owners  required  no  professional  assistance,  as  they  in- 
formed me  they  readily  cured  the  affection,  both  of  the  feet  and 
the  mouth,  by  the  application  of  salt  and  tar.  Are  these  dis- 
eaaes  to  be  attribute  to  the  same  cause  as  that  producing 
iofluenza  in  horses  ?  And  is  it  not  probable  that  the  influenza 
will  appear  amongst  mankind  during  the  approaching  winter 
or  spring,  as  it  succeeded  the  disease  in  horses  in  the  year 
1836?* 

"  As  I  lind  at  this,  the  eleventh  hour,  that  it  is  impossible  to 
be  personally  present  when  this  paper  is  submitted  to  the  con- 
sideration of  the  members  of  the  Association,  I  think  that  I  can- 
not do  better  than  atone  for  my  absence  by  instituting  a  few 
qneations  naturally  springing  out  of  the  foregoing  account;  not, 
however,  with  the  expectation  of  being  enabled  satisfactorily  to 
■olve  them,  but  in  order  to  provoke  profitable  discussion,  and 
a0brd,  as  it  were,  some  useful  pegs  which  may  serve  the  purpose 
of  suspending  many  valuable  lacta  and  observations  on.  For 
my  part,  I  shall  be  contented  to  act  as  the  humble  pioneer, 
leaving  to  you  the  mightier  task  of  clearing  away  all  impeding 
doubts  and  difficulties. 

"  1st.   To  what  came  mutt  we  attrilmte  the  iiifiuenza  f 

„  On  this  point  I  must  refer  to  the  theory  of  your  esteemed 
patron.  I  can  go  so  far  with  him  as  to  believe  that,  in  common 
with  the  epizootic  amongst  cattle,  it  is  derived  from  some  pecu- 
liar atmospheric  poison,  the  nature  and  the  source  of  which  I 
do  not  profess  to  know.  I  am  not  inclined  to  consider  that  it 
can  be  assigned  to  the  influence  or  fluctuation  of  the  weather, 
although  I  Delieve  that  these  changes  will  considerably  modify 
tbe  symptoms ;  for  it  is  a  fact  worthy  of  especial  attention,  that 
the  disease  made  its  appearance,  and  continued  to  prevail,  in 
this  neighbourhood,  during  the  prevalence  of  remarkably  fine 
and  genial  weather. 

"  2dly.  It  the  blood  the  teat  of  the  disease  ? 

**  In  my  opinion,  certainly  not ;  for  I  have  found  it  in  two  very 
oroositc  conditions,  —  one  slow  in  coagulating,  and  presentinga 
thick  and  firm  bufiFy  coat;  the  other  dark-coloured,  quick  in 

*  This  supposition  vas  verified  by  the  appearance  of  the  human  inliuenzB 
in  the  fatlowmg  spring.

from  ruminating  over  the  cud  of  reflection  during  four  years. 
My  own  opinion  is  iihown  by  my  practice.  I  cannot  say  that  it 
faaa  undergone  any  change,  or,  if  there  be  any,  it  slightly  leans 
towards  the  side  (without,  however,  entering  the  ranks)  of  the 
t^ponents  of  venesection.  I  take  it  for  granted  that  the  chief 
art  in  treating  the  diaease  is  to  know  when  to  bleed,  and  when 
to  absuin ;  being  guided  in  this  matter  chiefly  by  the  state  of 
the  pulse.  Where,  however,  I  have  not  bled  generally,  I  have 
witnessed  the  very  best  effects  from  local  bleeding.  It  has,  in  a 
few  hours,  relieved  the  tumefaction  of  the  eyelids,  and  the 
heaviness  of  the  head,  to  a  great  extent-  One  thing  is  most 
clear,  —  we  can  produce  a  very  great  effect  on  the  system  by 
moderate  bleeding. 

"  5thly.  /*  aperient  medicine  judicious  ? 

"  Tills,  too,  is  an  old  disputed  point.  I  am  myself  in  favour 
of  a  very  moderate  dose  at  the  commencement,  but  against  its 
repetition.  I  have  most  commonly  administered  Ave  drops  of 
croton  oil,  which  has  generally  produced  a  sufficiently  laxative 
efiect.  The  addition  of  a  few  drops  more  I  have  known  pro- 
dace  purgation.  I  am  inclined  to  believe  that  a  very  moderate 
action  on  the  intestines  will  hasten  the  recovery  of  the  patient. 

"  I  have  been  required  to  attend  several  cases  of  superpurga- 
tion  from  the  administration  of  full  doses  of  physic  in  this  dis- 
ease by  empirical  practitioners. 

"  In  one  instance  1  was  called  to  see  an  animal  which  one  of 
these  savans  had  previously  visited,  and  for  which  he  had  im- 
mediately put  in  practice  the  whole  list  of  his  remedies  — a  mild 
dose  of  physic,  a  rowel  in  the  brisket,  a  blister  on  the  throat 
(there  was  no  affection  of  the  air  passages),  and  he  was  just  going 
to  take  away  six  quarts  of  blood ;  but  this  the  employer  would 
not  permit  until  he  had  consulted  me.  I  attended  a  few  hours 
afterwards,  and,  from  the  pulse,  I  deemed  it  prudent  to  abstract 
about  five  or  six  pounds  of  blood,  which  proved  bufiy.  The 
next  morning  I  found  the  pulse  mucli  solder,  and  not  increased 
in  quickness,  the  fever  less,  and  the  general  symptoms  more 
favourable ;  but,  notwithstanding  this,  the  man  had  been  there 
before  roe,  and,  finding  the  physic  had  not  yet  operated,  he 
wished  to  give  another  dose,  and  to  take  away  six  quarts  more 
of  blood.  The  owner  fortunately  declined  his  further  assistance, 
or  he  would  certainly  have  destroyed  the  horse ;  for,  as  it  was, 
in  the  succeeding  night  severe  purgation  ensued,  anticipating 
which  I  hadleft  some  medicine  to  counteract  it.  The  appe- 
tite, which  a  few  hours  previously  had  been  improved,  was  now 
totally  gone,  and  the  animal  appeared  in  the  greatest  debility. 
His  recovery  was,  in  consequence,  very  much  protracted.

must  content  oureelvea  with  reaBoning  on  the  &cts  that  maj 
come  before  us,  and  be  satisfied  with  approaching  the  con- 
Hnea  of  prolMibility.  After  a  few  scattered  cases,  I  was  called  to 
attend  a  pony  at  aome  livery  stables.  A  few  days  afterwards  I 
had  another,  and,  in  all,  nine  cases  in  these  mewg.  At  this  time 
there  were  no  other  cases  in  the  neighbourhood  of  these  stabln, 
but  flix  weeks  afterwards  1  attended  a  case  at  another  mews  not 
more  than  100  yards  distant  from  the  former,  and  here  I  bad* 
one  after  another,  five  cases. 

"In  the  establishment  where  I  had  the  Rreatest  naroberof 
cases,  there  was  a  young  horse  that  indicated  the  approach  of 
strangles.  He  was  removed  to  the  hospital  stable,  in  which 
were  several  horses  with  influenza.  He  remained  there  eightor 
ten  days,  getting  on  pretty  well,  when  he  suddenly  showed  the 
symptoms  of  influenza,  in  addition  to  those  he  had  before,  and 
his  pulse  rapidly  rose  from  46  to  80.  This  certwnly  looks  like 
infection.  On  the  whole,  I  am  disposed  to  rcsard  the  disease 
as  infectious,  believing,  at  the  same  time,  that  the  greater  num- 
ber of  cases  are  produced  from  tlie  same  unknown  atmospherie 
cause."

GLANDERS    AND    FABCY. 

Ghtiidert. 


This  is  a  contagious  disorder,  and  one  that  is  generally  tliought 
incurable. 

[Its  symptoms  are  a  discharge  of  matter  from  one  or 
both  nostriU,  and  enlargement  of  one  or  botli  submaxillary 
glands.  When  one  nostril  is  affected  only,  the  corresponding 
gbiid  is  almost  invariably  found  enlarged.  The  membrane  of 
the  nostril,  called  the  Schiieiderian  membrane,  is  generally  of  a 
pale  or  leaden  hue;  and  sometimes  ulcerations  are  visible  on  iB 
surface.  The  discharge  usually  sticks  to  the  nostrils,  and  ii 
sometimes  white  and  thick,  but  oftener  of  a  greyish  aspect 
The  late  Professor  Coleman  divided  the  disease  into  two  kinds, 
which  he  termed  the  acute  and  the  chronic ;  the  former  being 
cases  in  which  ulcers  were  visible,  and  the  latter  in  which  none 
could  be  seen.  This  dofinitiou,  however,  though  sometimes 
correct,  is  too  arbilraiy  for  general  admittance;  for  there  are

eases  of  acote  glanders  occurring  without  any  ulcers  being  withio 
sight.  It  is  still,  however,  convenient  to  observe  the  terms  acute 
and  chronic,  to  denote  dilferent  varieties  of  the  disease.  A  dis- 
charge from  the  nostrils,  and  the  appearance  of  ulceration,  is  not 
alone  sufficient  to  establish  the  presence  of  the  disease ;  for  these 
ulcerations  are  sometimes  produced  by  the  acrid  nature  of  the 
discharge  from  catarrh.  If  the  discharge  is  accompanied,  from 
the  first,  by  an  oilensive  smell,  the  probability  is  that  the  case  la 
not  glanders,  but  ozena.  —  Ed.] 

The  great  number  of  horses  that  have  been  destroyed  by 
glanders,  especially  in  the  army,  and  in  establishments  where 
grest  numbers  of  horses  are  kept,  has  excited  particular  at- 
tention to  the  subject,  especially  in  France  and  Italy,  where 
many  attempts  were  made,  in  the  beginning  of  the  last 
century,  to  discover  a  remedy  for  it.  'I'he  reader  may  form 
some  idea  of  the  extent  of  such  losses,  when  informed  that 
large  innkeepers  have  been  nearly  ruined  by  them.  1  had 
occasion  to  condemn  eight  horses  at  one  time,  in  one  esta- 
blishment] which,  added  to  those  already  lost,  amounted  in  value 
to  5Q0L  In  one  regiment,  50  gtandered  horses  were  shot  in  one 
day.  The  Q3d  French  dragoons,  when  quartered  in  Italy,  in 
March,  1809,  had  76  horses  at  one  time  affected  with  glanders 
and , farcy,  or  suspected  of  being  so  affected.  Lafosse,  an  emi- 
nent French  veterinarian,  considered  it  as  a  local  disease,  and 
thought  he  had  discovered  a  successful  mode  uf  treating  ir,  which 
consisted  in  perforating  the  bones  which  cover  the  frontal  and 
nasal  sinuses,  and  injecting  through  the  openings  astringentand 
other  liquids.  After  this  opinion  had  been  published,  some 
English  farriers  made  trial  of  it,  and  by  others  detergent  lotions 
were  poured  into  the  nostrils;  the  nose  being  drawn  up  for  the 
purpose  by  means  of  a  pulley.  Attempts  were  also  made  to 
cure  it  by  arsenical  fumigations,  and  by  burning  out  the  swollen 
glands  under  the  jaws,  or  sloughing  them  out  by  caustics.  I'he 
various  preparations  of  mercury,  copper,  iron,  and  arsenic,  have 
likewise  been  tried,  and  after  all,  the  general  opinion  is  that  the 
glanders  is  incurable. 

From  the  circumstance  of  horses  having  sometimes  escaped 
the  disorder,  though  they  have  been  standing  in  the  same  stall 
or  stable,  or  drinking  out  of  the  same  bucket  or  trough  with  a 
glsndered  horse,  many  have  been  led  to  doubt  its  being  con- 
tamous ;  and  the  little  care  that  some  large  proprietors  have 
taken  to  prevent  the  spreading  of  the  disorder,  in  consequence 
of  such  opinions  having  been  held,  has  been  the  cause  of  very 
serious  losses ;  many  instances  of  which  have  come  within  my 
personal  knowledge.  That  the  glanders  is  contagious  has  been 
clearly  and  indisputably  proved  by  numerous  experiments;  and 
tl)e  manner  in  which  it  is  prop^ated  has  likewise  been  satis-

animal  is  rendered  more  su»ce])tible  of  the  coiitaf;toti  of  f^laii- 
(lers,  a*  well  iLS  of  other  di^eaies.  It  is  from  llii*  cause  that

while  among  horses  of  a  dillereni  < Inscription,  ili  progmi  U 
generally  slow,  Mr.  Uussel,  of  Kxvier,  had,  for  many  years, 
some  glandered  teams  of  horses  constantly  working  from  i^y- 
inoutli  to  Exeter.  Uitt  they  were  worked  with  moderation,  well 
fed,  and  taken  great  care  of.  I  attende<l  these  tea»»  for  several 
years;  the  horses  generally  li>oke<l  well,  and  in  excellent  con- 
dition. Many  of  them  lasted  four  or  live  years ;  some  fell  off 
I  oTier  a  few  months.  As  ilicy  droppeil  olf,  llie  teams  were  re- 
iitforcvd  by  horse*  that  liappeiu^d  to  become  glandered  on  on- 
Ollicr  lino  of  road  belonging  to  the  same  proprietor,  or  b; 
liartes  free  from  vlanders  that  did  not  luiit  other  teams,  or  were 
not  supposed  good  enough  for  tliem.  Such  Ivorsea  would  some- 
tinies  escape  the  contagion,  at  otiters  iliey  would  become  glan- 
tiered  in  a  few  weeks. 

After  some  time,  the  penon  who  bud  the  care  of  ibe  teams 
from  which  these  reinforcements  used  to  lie  drawn,  became  con- 
vinced, by  experiments,  of  the  contagious  nature  of  glandert, 
and  Uierefore  diligently  employed  every  precaution  tbiM  coultl 
be  thouglil  of  to  prevent  tlie  disorder  from  occurring.  In  con- 
1  sequence  of  this,  and  ilic  great  care  tliat  was  taken  on  the  line 
of  road  where  the  glundercd  horses  were  worked,  tlie  number 
gradually  diminisiied;  and  the  last  time  I  heard,  there  was  not 
one  left.  About  the  same  time,  I  attended  (be  horses  of  Messrs. 
Swc*l  and  Co.,  common  carriers,  of  Kxeier,  who  had  also  a 
team  of  gliiiKlercd  horses.  Here  the  woi'k  was  harder,  and 
BomewliAl  irrc};ular.  The  feeding  did  not  appear  to  be  so  care-

horses  in  any  respect  so  good  as  tliat  of  Mr.  Kussel's.     In  con- 


GLAHDSnS    AKD    FARCY.  217 

sequence  of  this,  the  horses  did  not  last  bo  long,  and  much  loss 
was  sustained,  bo  much  so,  that  the  two  concerns  aiforded  a 
striking  proof  of  the  truth  of  a  former  observation,  that  it  is  de- 
cidedly the  interest  of  all  horse  proprietors  to  work  those  useful 
animals  with  moderation,  and  feed  them  properly. 

It  has  been  said  that  glanders  has  oflen  been  produced  in  the 
cavalry  by  putting  the  horses,  immediately  after  coming  from 
camp,  where  they  are  constantly  exposed  to  the  weather,  into 
warm  stables,  and  giving  them  the  full  allowance  of  oats.  This, 
it  is  true,  has  often  brought  on  inflammatory  disorders,  which 
were  very  destructive,  and  sometimes  of  the  catarrhal  kind :  in 
which  case,  they  were  accompanied  with  a  discharge  from  the 
nostrils.  The  acrimony  of  the  matter  would  sometimes  even 
ulcerate  the  nostrils,  and  the  disease  would  tlien  be  considered  as 
a  decided  case  of  glanders.  1  have  known  the  distemper,  or 
epidemic  catarrh,  produce  this  effect. 

In  the  distemper  that  prevailed  in  the  summer  of  1799, 
several  horses  in  the  Scotch  Greys  were  said  to  have  become 
slandered  from  the  violence  of  the  distemper,  and  were  accord- 
ingly destroyed.  Such  cases  may  have  been  of  a  different 
nature  from  glanders,  though  resembling  the  disease  in  one 
mrmptom,  which  is  generally  considered  decisive  of  its  being  so, 
that  ia,  in  the  ulceration  within  the  nostrils. 

[Later  researches  have  fully  proved  that  glanders  may  be 
produced,  not  only  by  contagion  and  the  causes  before  enu- 
merated, but  also  by  catarrh,  either  in  its  common  or  epidemic 
forms,  by  strangles,  and  by  inflammation  of  the  lungs.  In  such 
cases  these  diseases  are  said  to  degenerate  into  glanders.  In  the 
last  three  cases  that  came  under  my  attention,  one  was  preceded 
hy  strangles,  anotlier  by  bronchitis,  and  the  third  by  catarrh, 
^at  form  of  the  disease  called  bastard  strangles,  in  which  the 
glandular  swelling  does  not  suppurate  kindly,  out  becomes  hard 
and  scirrhous,  is  very  apt  to  degenerate  into  glanders.  —  Ed.] 

In  1784,  a  law  was  enacted  by  the  French  government  to 
prevent  any  one  from  keeping  a  glandered  horse,  under  a 
penalty  of  500  livres.  Every  animal  suspected  of  glanders  had 
the  words  "  suspected  animal"  impressed  in  green  wax,  on  his 
forehead ;  and  the  penalty  for  selling  such  an  animal,  or  offering 
him  for  sale,  was  500  livres. 

Persons  having  suspected  animals  were  to  report  the  same 
immediately  to  the  mayor,  syndics  of  villages,  or  other  proper 
authorities,  under  a  penalty  of  500  livres.  Such  horses  were 
then  inspected  by  experienced  veterinarians,  or  other  competent 
judges,  appointed  by  the  mayor  or  other  officer,  and  if  found 
glandered  were  destroyed.  If  only  suspicious,  or  suspected, 
they  were  marked  in  the  forehead  as  before  described.  At  the 
same  time,  a  pamphlet  on  the  glanders  was  published  by  order

hortcs  have  been  known  to  get  rid  of  the  disorder  while  working 
in  thnc  teams;  and  sound  horses  thai  have  been  put  in  occa- 
siohnlly  to  fdl  up  the  toaiiui,  especially  old  horses  have  neaped

that  lias  led  rnniiy  |«  believe  that  the  glanders  is  not  contagious. 
Tlie  second  stage  of  glaiiilers  is  marked  by  ulceration  wilhhi 
the  nostrils,  or  an  appearance  in  tl>e  matter  which  indicates 
nloeration,  though  sometimes  too  high  up  (o  be  seen.  'I'he 
matter  is  in  larger  qiiantiiy,  more  glutinous,  slicking  about  ilie 
margin  of  the  nostril  and  upper  lipe,  aud  sontelimcs  obsirucliiig 
tlio  parage  of  air,  so  that  the  horse  makia  a  snuftling  noise  in 
brcMbing.  The  matter  is  sometimes  streaked  with  blood  ;  and  the 
horse  sometimes  bleeds  from  the  nostrils  in  working  Wi>en  diis

the  first  Blage,  though  an  offensive  smell  is  by  many  supposed 
to  bo  a  decisive  mark  of  glanders.  In  the  second  stage,  the 
matter  generally  runs  from  both  nostrils ;  the  glands  under  tbti

bone.  They  are  also  generally  more  tender  than  in  the  first 
sti^;  the  inner  comers  of  the  eyes  are  mattery.  The  horse 
loses  flesh  and  strength,  stales  more  than  usual,  coughs,  and  at 
length  dies  in  a  miserable  condition,  generally  farcied  as  well  as 
pandered.*     In  the  pamphlet  before  noticed,  by  Chabert  and 

■  Although  the  diseaae  u  here  divided  iato  the  ^t  and  second  stage,  it  is 
not  enentiHlthat  in  each  case  the  former  should  precede  the  latter,  for  BOme- 
times  the  acute  only  is  present,  and  the  horse  speeilily  dies  if  not  destroyed. 
Id  other  instances,  the  acute  stage  may  be  succeeded  by  the  sub-acute.     It 
may,  however,  be  obserrcd  that  the  first  stage  never  ends  in  death,  but  alirays 
in  the  aecoud  stage,  before  the  disease  proves  fataL     Besides  these  stages, 
ghuideTS  sometimet  assume  a  still  more  insidious  appearance,  in  which  the 
SiiKbarge  is  so  slight,  and  the  enlarged  gland  so  trivial,  as  not  only  to  deceive 
Ae  ignorant,  but  often  to  mislead  the  well-instructed  practitioner.    The  dis- 
charge is  thin,  and  appears  no  more  than  a  slight  increase  of  the  natural 
diacharge,  and  the  Bub-maxiUary  swelling  is  no  urgcr  than  a  bean,  though 
bard  and  indurated.     Such  cases  as  these  have  proved  of  irreparable  injury 
to  many  horse  proprietors,  from  the  symptoms  not  being  sufCiciently  urgent  as 
to  escite  alarm  ;  and  when  a  veterinary  surgeon  has  given  his  opinion  that 
nch  case  was  one  of  glanders,  there  have  not  been  wanting  plenty  of  farriers 
and  others  who  have  altogether  contemned  such  an  opinion,  and  for  a  time, 
at  least,  have  exulted  over  th^  own  superior  sagacity.     Mr.  James  Turner 
rdates  a  striking  instance  of  this,  in  which  his  advice  was  diiregarded,  and  a 
horse,  with  these  insidious  appearances,  was  allowed  to  mix  with  other  horses, 
to  several  of  wbich  he  communicated  the  disease  in  the  course  of  a  few 
months.     Several  iustsncea  of  a  similar  oature  have  occurred  in  my  own 
pvctice.     One  in  which,  ailer  atteuding  a  horse  with  a  suspicious  gleet,  I 
pronounced  hira  glandered ;  and  to  be  still  more  certain,  inoculated  a  donkey 
with  the  matter,  which  communicated  the  disease  in  a  few  days.     By  some 
noderiund  means  the  donkey  was  smu^led  away  contrary  to  the  wishes  of 
the  owner,  and  destroyed  without  affording  me  the  op|)ortunity  of  examining 
the  body.    The  horse  was  shortly  afterwards  sold  for  51.,  and  then  a  neigh- 
bouring farrier  offered  to  cure  him,  which,  according  to  the  report  which  he 
circulated,  he  accomplished  in  a  few  weeks,  etating  that  the  horse  had  never 
been  glandered.    Shortly  afterwards  the  horse  was  sold  by  the  owner,  a  low 
dealer  (rather  too  low  for  the  thafUof  the  law  to  affect  him),  for  20/.     He  was 
turned  with  other  horses,  to  whom  he  communicated  the  disease,  and  I  wei 
requested,  some  months  afterwards,  to  give  a  certificate  as  to  the  state  the 
borse  was  in  whilst  under  my  care.     Another  case  occurred  within  a  few 
months  of  the  other,  in  which  the  symptoms  were  not  so  xtrongty  marked, 
and  therefore  more  insidious.     A  young  carriage  horse  belonging  to  a  noble- 
man now  deceased,  was  ill  with  a  severe  catarrh  in  the  early  part  of  1839,  and 
wu  for  some  time  under  the  care  of  a  veterinary  surgeon  of  Bath.     He  got 
conriderably  better,  but  the  discharge  from  the  nostril  continued.     A  few 
months  afterwards  the  establishment  coming,  according  to  custom,  into  mv 
Dcighbourhood,  I  saw  ttie  horse,  and  recommended  that  he  should,  by  aU 
means,  be  seiiaraled  from  the  other  horses,  which  was  accordingly  done,  and 
he  was  placed  under  my  care.     The  symptoms,  at  this  time,  were  a  rather 
considerable  discharge  of  white  healthy  looking  matter  from  the  near  nostril, 
•ml  enlargement  of  the  corresponding  submsnillBry  gland,  which  felt  hard, 
and  was  about  the  size  of  an  ^g;  no  ulceration  could  be  perceived,  and  the 
animal  looked  in  other  respects  healthy  and  well.     The  horse  was  valuable, 
having  recently  cost  TO/.     The  treatment  was  pursued  for  severs!  weeks,  nnd 
consisted  of  blisters  and  selons  to  the  throat  and  glands,  and  vegetable  and  mine- 
ral tonics  internally.    Under  this  treatment  the  horse  got  considerably  better ;

nostril,  or  in  both  eyes,  when  the  running  is  from  both  nostrils. 
When  these  symptoms  appear  the  disease  soon  proceeds  to  a  fatal 
termination.  The  above  symptoms  are  not  all  peculiar  to 
glanders,  but  may  take  place  also  in  strangles,  bastard  strangles, 
peripneumony,  cUstemper  {morfondure)  and  pleurisy.  The  dis- 
charge of  a  glutinous  matter  from  the  nose,  the  swelling  of  the 
glands  under  the  jaw,  and  the  ulceration  within  the  nostrils  are 
symptoms  which  occur  in  the  above  diseases  as  well  as  in  glanders, 
but  with  this  essential  diifercnce.  In  ihe  latter,  the  three 
symptoms  just  noticed  generally  occur  about  the  same  time, 
which  is  not  the  case  in  glanders;  and  are,  in  the  first  instance, 
acute  and  inflammatory,  and  such  as  to  excite  apprehension  of 
immediate  danger.  1  ney  go  through  their  course  in  a  short 
time,  the  running  from  the  nose  gradually  diminishes,  the  blood 
is  depurated,  and  a  perfect  recovery  takes  place.  Glanders,  on 
the  contrary,  b  extremely  slow  in  its  progress :  the  first  degree 
often  continuing  a  considerable  time ;  and  it  is  only  towards  the 
end  of  the  second  degree,  or  the  beginning  of  the  third,  that 
the  symptoms  appear  to  indicate  an  alteration,  or  disease  of  the 
internal  organs.  This  slow  pn^ress  of  glanders,  and  especially 
its  continuing  for  some  time  without  any  apparent  injury  to  the 
animal's  health  and  condition,  the  state  and  progress  of  the 
swelling  under  the  jaws,  and  the  ulceration  within  the  nostril, 
furnish  such  clear  marks  of  distinction  between  those  diseases 
and  glanders,  that  they  cannot  well  be  mistaken  for  each 
other." 

It  is  a  remarkable  circumstance  tliat  glanders  cannot  be  com- 
municated by  applying  the  matter  which  is  discharged  from  the 
nose  of  a  glandered  horse  to  the  nostrils  of  a  sound  horse,  unless 
there  be  an  open  wound  or  sore,  everf  though  a  piece  of  lint 
•oaked  in  the  matter  be  put  up  the  nostrils,  and  kept  in  contact 
with  the  pituitary  membrane  for  a  short  time ;  or  even  if  the 
matter  be  thrown  up  the  nostrils  with  a  syringe.  But,  if  the 
smallest  quantity  of  matter  be  applied  in  the  way  of  inocula- 
tion, either  to  the  membrane  of  the  nostrils,  or  to  any  part  of 
the  body,  a  glanderous  ulcer  will  be  produced,  from  which  farcy 
buds  and  corded  lymphatics  will  proceed.  After  a  few  weeks 
the  poison  will  get  into  the  circulation,  and  the  horse  will  be 
completely  glandered.  The  circumstance  of  glanders  not  being 
communicated  by  applying  matter  to  the  nostril,  enables  us  to 
account  tor  a  horse  escaping  the  disorder,  as  he  sometimes  does, 
after  being  put  into  a  glandered  stable,  or  standing  by  the  side 
of  a  glandered  horse.     I  believe,  however,  that  gtandei's  is  fro- 

r*nt]y   communicated  by  (accidental)  inoculation ;   and  that 
re  is  only  one  other  way  in  which  it  can  be  communicated, 
that  is,  by  swallowing  the  matter  which  flows  from  the  nose  of  a

tltat,  to  commiiiiicaie  the  ginndei-s,  the  matter  must  be  applied 
to  a  scratch  or  wound  fj-e^li  made,  and  not  to  a  sore  on  whidi 
matter  has  formed.  A  eound  horse  tuis  been  inoculated  witli 
glanderous  matter  that  luid  been  mixed  with  ten  ttmea  its  weight 
of  water.  This  produced  some  degree  of  inllammation,  ana  a 
ainall  ulcer  of  a  eusptciouB  appearance;  but  after  two  or  three 
days,  it  got  cjuite  well.  This  stiowa  that  glanderous  nuiiter  may

Mccrettoii  from  the  lower  part  of  a  glutidervd  horse's  nottrili,

niunicated  in  so  violent  a  degree  that  the  animal  is  genenlly 
destroyed  by  it  in  a  few  days.  The  same  effect  is  produced 
when  glanderous  matter,  mixed  with  a  little  warm  water,  is  in- 
jected  into  the  jugular  vein  of  a  sound  horse. 

A  horse  aiFected  with  glanders  may  inoculate  himself,  and 
tliereby  produce  the  farcy.  I  liave  known  this  happen  to  a  horse 
while  at  gnus.  The  hor^e  had  an  itching  in  his  hind  leg,  whicti 
led  him  to  rub  and  bite  the  part,  and,  at  the  eame  time,  rub  on 
it  the  glanderous  matter  which  flowed  from  his  nostril,  lite 
possibility  of  this  circumstance  taking  place  may  be  easily  proved 
by  inoculating  a  glandcred  borse,  in  any  part  of  his  Ixtdy,  with 
lomc  of  his  own  matter.     There  are  many  ways  in  which  a

QLAMDERS    AND    FARCV.  2*i3 

sonnd  hone  may  be  accidentally  inoculated  with  the  matter  of 
glanders,  for  the  slightest  scratch  in  any  part  of  the  body  is 
sufficient.  Horses  that  are  cleaned  with  a  curry  comb  are  very 
liable  to  be  scratched  in  those  parts  where  the  bones  are  pro- 
minent, such  as  the  inside  of  the  hock  and  knee,  the  shank  bones 
and  the  bead.  To  such  scratches  glanderous  matter  may  be 
uiplied  by  the  hands  of  the  groom  alter  he  has  been  examining 
the  nose  of  a^landered  horse,  or  wiping  off  the  matter  from  his 
nostrils ;  or  by  the  horse  himself  transferring  glanderous  matter 
from  the  nose  of  a  diseased  horse,  or  from  the  manger,  or  other 
part  where  any  matter  has  been  deposited,  for  horses  are  very 
fond  of  rubbing  their  noses  against  the  manger  or  stall,  and  a 
glandered  horse  will  generally  try  to  rub  off  the  matter  from  his 
nose  against  the  manger,  the  rack,  the  stall,  or  against  another 
horse ;  and,  if  a  sound  horse  happened  to  stand  by  one  that  is 
glandered,  they  will  often  be  seen  nabbing  or  gently  biting  each 
other,  or  rubbing  noses.  In  short,  having  proved  that  glanders 
is  thus  communicated,  we  can  conceive  a  variety  of  ways  in  which 
a  horse  may  be  accidentally  inoculated.  When  a  horse  has  been 
twitched,  be  generally  rubs  his  nose  and  Itps  with  considerable 
force  against  the  manger,  and  may  thus  easily  inoculate  himself 
with  a  glandered  splinter.  Now,  the  parts  where  the  local  farcy 
first  appears  are  those  most  likely  to  be  accidentally  inoculated, 
that  is,  the  inside  of  the  hocks  and  knees,  the  shanks,  the  lips, 
the  under  jaw,  where  grooms  are  often  trimming  off  the  long 
hair  with  sharp-pointed  scissors,  or  singeing  them  with  a  candle, 
and  often  causing  an  itching,  which  makes  the  horse  rub  the 
part  against  the  manger.  In  this  way  the  heels  also  are  often 
wounded.  Horses  that  are  too  highly  fed  and  little  worked  are 
liable  to  itching  humours,  which  make  them  nab  or  bile  their 
skin,  and  scratch  the  hind  leg  with  the  opposite  foot ;  and  we 
may  often  see  them  bite,  rub  with  the  nose,  and  scratch  with  the 
hind  foot,  alternately,  the  other  leg. 

■  If  we  take  all  the  foregoing  circumslancos  into  consideration, 
and  recollect  that  in  M.  St.  Bel's  experiment  a  month  elapsed 
before  the  first  horse  became  glandered,  and  that,  from  nu- 
merous experiments  and  observations  made  with  regard  to  acci- 
dental and  intentional  inoculation  with  glanderous  matter,  some 
days  will  elapse  before  any  ulcer  or  chancre  is  produced,  a  week 
or  two  before  farcy  buds  or  corded  lymphatics  appear,  and, 
probably,  a  month  or  two  before  the  running  from  the  nostril 
comes  on  (except  when  an  ass  is  the  subject  of  experiment), 
■^  if  we  reflect  upon  all  these  circumstances,  there  will  be  no 
difficulty,  I  think,  in  admitting  the  following  positions,  or 
rather  inferences  or  conclusions,  with  respect  to  glanders,  viz. 
that  glanders  is  a  contagious  disorder,  which  is  communicated 
by  inocuUtion,  and  by  swallowing  the  matter,  and  not  by  effluvia

Btficlly  tho  case  with  rcganl  to  j;landci-ous  inoculation,  it  having 
been  proved  that  by  introdueing  a  considerable  ciuantiiy  of  mat- 
ter, tl)e  hori^c  is  speedily  destroyed.  The  sanie  rule  will  pro- 
bably  be  found  to  hold  good,  in  a  certain  degree,  when 
glanderous  matter  is  swallowed;  but  t)ie  horse's  stomach  pot- 
•esses  a  wonderful  power  of  misting  the  impression  of  poisonoai 
matter,  as  tias  bv  cnproved  by  tl»e  large  doees  of  arsenic,  corro- 
sive sublimate,  «iigitr  of  lead,  &c.,  that  have  at  dilTereni  linin 
been  given,  by  way  of  cxnerinicnt,  to  glaiidered  horaea.  A 
liorse,  ttirreforc,  may  possibly  swallow  one  larse  dose  of  glan- 
derous matter  wjiliotil  b<-ing  injured  by  it,  while  a  repetition  of 
smaller  doses  will  rt-udily  produce  the  di$ord«r.  M.  St.  Bel 
gave  it  <laily  for  a  week  ;  and  the  same  method  has  beeu  pur- 
sued  in  other  ex|M'riinents. 

I  (Uii  inclined  U>  bi-lievc  that  the  fli«niicr  i«  more  readily  caugbl

drinkiiig  it  with  waU'r,  as  in  the  former  ease  it  is  so  intimately 
mixed  with  the  food  by  mastication.  M.  Sl  Ilcl  placed  two 
lound  hones  by  a  gUndvi-ed  hone,  drinking  out  of  the  same 
Mil  and  eating  out  of  the  tame  manger.  One  of  the  sound 
hones  was  six  yearn  old,  and  jiut  lakvn  from  grass;  the  other 
nine  ycai's  old,  and  taken  from  i-cgular  work.  I'he  first  showed 
i-vident  »igiis  of  gliinders  at  the  expiration  of  thirty-four  davs; 
it  fully  (k'clurrd  itself  in  the  M-cond  at  the  end  of  six  we^u. 
Two  horses  in  good  health,  the  one  seven,  the  other  eleveiif 
yenra  old,  both  just  taken  from  work,  were  placed  by  a  horse 
tiutl  had  the  ^Ian<l<'r».  TIk'  former  caught  the  disease  in  6%- 
two  dayi,  iht.-  other  in  thn-e  montliK.  A  hone  thirteen  yean 
old,  very  lean,  was  made  to  <lriiik  the  *ame  water  out  of  the 
tame  pail  with  a  horse  that  Iiud  the  glander»,  and  continued  so 
to  do  for  two  months :  he  did  not  ciitch  the  ditoi-der.  A  hone 
nine  vears  old,  in  tolerable  condition,  was  placed  by  a  horse  tliAt 
had  tlie  glanders  in  the  tai>l  stage  of  ihe  diioi'dor :  hv  caught  it 
at  the  end  of  forty-din-e  dayh.  M.  St.  IJel'i  irinU  by  inoculation 
were  attended  with  a  dltlerent  result,  which  1  am  at  a  loss  to 
account  for;  as  I  have  clearly  proved,  by  immerous  exiMiimcnls, 
that  glanders  may  be  commnnicaled  almost  with  certainty  by 
iiiocuTatiofii  es]>eciany  to  young  asses.  Old  liorsea  appear  to  ofler 
the  greatest  resistance  to  it,  both  by  ihc  way  of  iitoculnlioii  and 
by  swallowing  the  matter.  M.  St.  Bel  inocul«te<l  three  old 
horses  with  glanderous  matter,  and  they  all  escaped.  He  adds, 
this  experiuicni  was  repealed  on  various  hontc*  of  all   agtt) 


QLAMDERS    AND    FARCY.  235 

without  producing  any  effect.  It  waa  also  performed  on  an  ox, 
a  sheep,  and  a  dog,  without  impairing  in  the  least  the  health  of 
these  animals.  I  have  known  a  horse,  fifteen  years  old,  stand 
by  the  side  of  a  glandered  horse,  constantly  feeding,  drinking, 
and  working  with  him  for  many  months,  without  catching  the 
disorder;  and  I  had  occasion  to  inoculate  another  old  horse 
several  times  hefore  I  could  produce  the  disease,  and  at  last  it 
waa  about  three  months  before  the  glanders  took  place  in  him. 
In  younger  horses,  and  especially  in  asses,  the  disease  is  pro- 
duced with  great  certainty  by  inoculation.  In  doubtful  cases, 
that  is,  when  there  is  much  difficulty  in  determining  whether 
the  discharge  from  a  horse's  nostril  is  glanderous  or  not,  and 
such  cases  uilen  occur,  I  have  for  some  lime  made  use  of  a 
young  aES,  which  costs  only  a  few  shillings,  in  order  to  decide 
the  point  beyond  all  possibility  of  mistake.  If  the  matter  is 
really  glanderous,  a  peculiar  kind  of  sore  or  chancre  will  be 
produced  by  inoculating  the  young  ass  with  it  in  any  part  of  the 
body.  From  this  ulcer,  corded  lymphatics  or  veins,  as  they  are 
termed,  will  proceed,  and  farcy  buds  or  small  tumours  will  take 
place.  After  a  week  or  two  the  animal  will  begin  to  run  at  the 
nose ;  and  then,  in  a  short  time,  he  will  be  completely  glandered. 
The  disease  in  this  animal  is  almost  always  quickly  fatal.  If  the 
matter  is  not  glanderous,  no  effect  whatever  will  be  produced  by 
it:  In  the  army,  and  in  establishments  where  many  horses  are 
kept,  this  will  be  found  a  valuable  test  for  determining  with 
certainty  the  nature  of  a  discharge  from  the  nostril.  However 
mild  the  glanders  may  be,  though  no  kind  of  ulceration  can  be 
•een  within  the  nostril,  and  the  quantity  of  matter  discharged  is 
bat  small,  and  the  animal  in  good  health  and  condition,  the  ass 
will  be  as  certainly  infected  by  the  matter  as  if  the  disease  were 
in  the  last  stage,  or  in  the  most  virulent  degree. 

The  following  is  the  method  of  performing  the  inoculation :  — 
Cut  off  a  little  nair  from  the  side  of  the  neck  or  any  other  part 
of  the  body,  for  about  the  space  of  half-a-crown ;  then  take  a 
lancet  and  pass  it  under  the  cuticle  or  scarf-skin,  for  about  a 
quarter  of  an  inch :  it  should  not  wound  the  skin  much,  but  be 
aofficicntly  deep  to  tinge  the  lancet  with  blood,  or  make  one  or 
two  drops  of  blood  appear.  The  matter  may  be  introduced  into 
this  opening  {first  wiping  off  the  blood)  by  means  of  a  thin  slip 
of  wood,  of  the  form  of  a  lancet.  If  the  matter  is  glanderous, 
the  part  will  become  sore  in  two  or  three  days,  and  a  scab  will 
form  on  it,  which  in  a  few  days  will  be  thrown  off,  leaving  a 
peculiar  kind  of  ulcer,  which  will  often  spread  rapidly,  causing 
a  painful  swelling  of  the  adjacent  parts,  with  corded  lymphatics 
and  farcy  buds.  In  about  a  fortnight,  sometimes  less,  the 
glanders  will  appear.  No  other  matter  will  produce  this  effect. 
There   is   only  one  kind  of  matter,  besides  that  of  glanders,

7Xe  Sainn  of  Glanders.  —  [There  is  tlill  muc)>  difft-rvnce  of 
opinion  as  to  ihe  real  nature  of  glanders.  Professor  Coleniaii 
considcrod  that  it  was  a  specific  iiiflaromalion  of  the  membrane 
of  the  nostrils  produced  by  a  poison  in  the  blood,  and  on  trans- 
fusing the  blood  of  a  glutidered  horse  into  the  veins  of  an

Iriittiae  on  the  disease,  considers  it  to  be  of  a  tuberculous  uatuitv 
iukI  tliat  it  i«  always  preceded  by  tubercles  in  the  lungs,  tbsl

into  pus  anil  occasion  ulcers  bulb  in  the  lungs  and  the  nasal 
membtane. 

Proteiwr  Howell  in  some  measure  coincide*  witlt  ibeae  viwtk 
and  has  found  ihnl  on  inoculating  a  lu-»ltby  donkey  witk 
glanderous  matter,  it  has  piwlueed  tu)>ercles  in  i)ie  luiigi  in  a 
very  short  space  of  time. 

Tlicw  views  arc  deserving  of  great  wnghl,  but  wc  cannot 
altogether  coincide  wiih  them:  for,  although  [leriinps  in  llic 
lUBJorily  of  cases  tubercles  are  found  in  the  nings  of  glandered 
liorscs,  yet  lliere  are  other  instances  in  which  (here  are  uone  to 
be  found  there  or  eUewhcre.  'I'he  particular  seat  of  glandm 
is  certainly  the  membrane  lining  tlie  nostrils  and  chambers  of 
tl>c  head,  although  in  a  great  number  of  cases  the  lungs  arc 
likewise  involved.  We  cannot  say  wlicthcr  in  all  cases  the  con- 
stitution is  affected,  or  whether  in  some  instances  the  disease  is 
entirely  local :  but  in  the  subject  chosen  bv  Professor  Coleman 
for  cxpcrimcDt,  it  wwt  clearly  proved  that  the  blood  was  infected. 
There  is  evidently  a  much  greater  predisposition  in  some  horse* 
to   receive    llie    disoate,    citlicr  from  infection   or    otherwise. 


GLANDERS  AND   7ARCr.  227 

Horses  with  narrow  chests,  long  legs,  and  light  carcasses,  are 
more  liable  to  take  the  disease  itian  others;  and  some  consider 
that  colour  has  something  to  do  with  the  matter.  Some  years 
since,  during  my  pupillage  at  the  Veterinary  College,  having  to 
read  a  paper  on  glanders  to  the  Veterinary  Society,  I  examined 
the  record  of  cases  kept  there  for  many  years,  and  I  found  that 
the  number  of  cbesnut  glandered  horses  was  greater  than  of  any 
other  colour. 

Next  to  that  of  curing  this  disease,  it  is  desirable  to  be  able  to 
decide  in  difficult  and  obscure  cases  as  to  its  actual  presence;  and 
on  this  matter  the  opinion  of  veterinary  surgeons  is  frequently  de- 
manded. Grooms  and  farriers  more  frequendy  give  a  wrong 
than  a  right  opinion,  imagining  when  the  symptoms  are  very 
mild,  that  the  disease  cannot  be  glanders,  and  oflen  pronouncing 
a  horse  to  be  glandered  when  he  has  only  the  strangles  or 
catarrh.     The  first  mistake,  however,  is  the  most  frequent 

In  examining  a  suspected  case,  if  we  find  a  discharge  of 
matter  from  one  nostril,  and  a  portion  of  it  sticking  to  the 
entrance  with  a  hard  and  fixed  enlargement  of  the  submaxillary 
gland,  ahhough  the  enlargement  may  be  slight,  and  the  dis- 
charge inconsiderable,  yet,  if  these  symptoms  have  exbted  for 
two  or  three  months  or  upwards,  we  may  safely  decide  the  case 
to  be  one  of  glanders,  even  if  there  be  no  ulceration  witliin 
sighL  When  these  symptoms  exist,  but  there  is  no  means  of 
ascertaining  the  history  of  the  case,  we  may  justly  consider 
that  the  probability  is  in  favour  of  its  being  one  of  glan- 
ders; and  this  opinion  will  be  greatly  strengthened  if  there 
are  any  mysterious  or  suspicious  circumstances  connected  with 
it,  such  as  the  horse  having  been  sold  at  a  very  low  rate.  If, 
however,  we  cannot  trace  the  history  of  the  case,  and  the  animal 
is  of  any  value,  it  will  be  desirable  either  to  keep  it  fur  some 
weeks,  or  otherwise  to  inoculate  an  ass  with  the  suspected 
matter. 

If  both  nostrils  are  affected,  and  the  symptoms  are  hut  slight, 
the  case  is  not  so  decided  as  if  one  only  is  affected. 

If  tliere  be  a  cough,  and  the  other  symptoms  are  tltght,  the 
chances  are,  that  it  is  not  a  case  of  glanders,  for  although  cough 
is  sometimes  present  in  glanders,  yet  it  denotes  some  pulmonary 
aflection,  in  which  case  tlie  symptoms  of  glanders  are  usually 
Kvere.  The  absence  of  a  cough,  therefore,  and  the  presence  of 
the  other  symptoms,  is  very  suspicious.  The  existence  of  uicera 
m  the  nostrils,  U^ether  with  a  discharge,  is  not  alone  sufficient 
prooft  of  ganders  being  present,  for  these  symptoms  are  some- 
times produced  by  catarrh,  the  previous  existence  of  which  it  is 
desirable  to  ascertain.  If  the  discharge  from  the  nose  be  very 
offensive  when  it  first  appears,  the  probability  is,  that  it  is  not  a 
case  of  glanders,  although  ulcers  may  be  seen.     Those  symptoms

communicated,  it  is  needless  to  say  any  thing  of  tho  mode  of 
prevention,  except  briefly  observing,  that  it  can  be  accomplished 
only  by  preventing  any  glanderous  matter  from  coming  near  a 
horse,  or  mixing  with  his  food  or  water;  and  that  the  only 
method  of  purifying  an  infected  stable,  is  to  remove  every  thing 
on  which  glanderous  matter  may  have  fallen,  and  to  wash  and 
scrape  the  fixtures,  such  as  the  rack  and  manger,  thoroughly. 
I  have,  in  a  former  edition,  advised  a  fumigation  with  the  gas 
which  arises  from  a  mixture  of  common  salt,  manganese,  and  oil 
of  vitriol,  because  I  have  found  that  glanderous  matter  which 
has  been  exposed  to  this  gas  is  rendered  quite  innocent,  though 
an  ass  be  inoculated  with  it ;  and  I  have  directed  the  stable  to 
be  first  thoroughly  cleansed,  because,  if  any  dry  hard  glan- 
derous matter  should  remain,  the  water  employed  in  cleansing 
the  stable  will  have  moistened  it,  and  thereby  enable  the 
fumigation  to  mix  with  it,  and  destroy  its  poisonous  quality. 

[Some  persona  fancy  that  it  is  necessary  to  pull  down  and 
remove  the  racks  and  mangers  of  a  glandered  stable.  This, 
however,  is  altogether  unnecessary.  The  following  plan  will  be 
found  at  once  efiectual,  convenient,  and  economical :  —  Let  the 
whole  of  the  stable,  or  at  least  every  part  to  which  the  diseased 
animals  could  possibly  have  had  access,  be  washed  with  a  solu- 
tion of  chloride  of  lime,  and  the  following  day  well  scrubbed 
with  soap  and  water,  and  as  soon  as  it  is  dry  again,  washed  with 
the  chloride  of  lime.  In  a  few  days  allerwari£,  it  may  be  used 
without  any  danger.  —  Ed.] 

Trfotment.  —  I  have  already  observed  that  a  glandered  horse 
has,  in  several  instances,  been  known  to  gel  entirely  free  from 
the  disorder  while  employed  in  moderate  work,  and  carefully 
led  and  attended,  without  taking  any  medicine:  I  have  also 
seen  the  disorder  cured  by  mercury,  and  have  known  instances 
of  farcy  being  so  cured.  The  general  opinion,  both  of  English 
and  French  veterinarians,  is,  that  glanders  is  incurable,  and 
that  fercy  is  curable.  According  to  my  experience,  there  is 
seldom  any  difficulty  in  curing  farcy,  when  it  is  a  local  disorder, 
merely  by  local  applications ;  but  such  cures  are  generally  fol- 
lowed by  glanders,  there  being  often  a  considerable  interval 
(from  a  few  weeks  to  a  few  months)  between  the  disappearance 
of  fercy  and  the  appearance  of  glanders.  Before  any  attempt 
is  made  to  cure  a  glandered  horse,  with  a  view  to  publishing  the 
case  if  it  prove  successful,  it  would  be  right  to  make  it  appear 
satisfactorily  that  the  horse  is  really  glandered.  This  rule  has 
been  seldom  attended  to ;  for,  in  general,  when  such  cures  have 
been  published,  or  talked  of,  it  has  been  merely  asserted  that 
the  horse  had  the  glanders.  Now,  it  is  well  known  that  there 
are  diseases  which  resemble  glanders,  and  that  the  most  ex- 
perienced practitioners  are  sometimes  unable  to  give  a  decisive

it  should  never  be  forgotten,  that  by  making  a  horse  comfortable 
and  cheerful,  we  improve  the  digestive  functions,  and  thereby 
strengthen  the  const  itution. 

The  injected  horses  that  gradually  got  well  without  medicine, 
in  Mr.  Russel's  glandered  teams,  owed  their  recovery,  I  have 
no  doubt,  in  great  measure  to  the  comfortable  state  they  were 
kept  in,  being  taken  great  care  of,  having  always  the  best  food 
aad  good  stEdoles,  and  being  always  with  their  companions,  and 
in  moderate  but  r^ular  work. 

QProfessor  Sewell  has  for  some  years  been  in  the  habit  of 
giving  the  sulphate  of  copper,  in  large  doses  of  four  and  six 
drachms,  which  being  administered  in  the  form  of  a  draught, 
and  with  plenty  of  linseed  meal,  is  not  found  to  produce  that 
erosion  of  the  stomach  which  the  same  dose  given  as  a  ball 
would  occasion.  This  medicine  is  doubtless  a  i>owerful  tonic, 
and  thus  assists  the  constitution  of  the  animal  in  throwing  off 
the  disease;  but  Mr.  Sewell,  I  believe,  considers  that  it  has  in 
addition  some  specific  action  on  the  malady.  In  addition  to 
this  Mr.  Sewell  frequently  inserts  setons  over  the  &ce.  By 
this  treatment  cures  have  unquestionably  been  effected,  and 
Mr.  Sewell  used  for  many  years  a  mare  that  he  had  cured  of 
glanders.  These  successnil  cases,  however,  are  exceedingly  few, 
compared  with  the  number  submitted  to  treatment. 

Mr.  Vines,  in  a  work  published  some  years  since  on  glanders, 
recommends  powdered  cantharides  in  doses  of  four  to  twelve 
grains,  together  with  gentian  and  ginger,  one  to  three  drachms 
each,  and  caraway  seeds  one  to  two  drachms.  A  ball  thus  com- 
posed he  has  administered  daily  to  glandered  horses,  and  in 
some  cases  with  success.  Other  practitioners  likewise  testify  to 
the  valuable  tonic  properties  of  this  medicine  thus  administered, 
and  in  numerous  instances  I  have  seen  ils  good  effects. 

Mr.  Siorry  relates  several  instances  of  glandered  horses  cured 
by  him  by  fumigating  the  nostrils  with  carbonic  acid  gas,  assisted 
l^  tonic  medicine. 

Creasote  has  been  used  with  success  in  glanders  of  the  human 
subject  as  a  topical  application  to  the  ulcers,  and  il  has  in  a  few 
instances  been  tried  on  the  horse  with  good  effecL  I  have, 
myself,  in  a  case  of  glanders,  entirely  stopped  the  nasal  dis- 
cha^e  and  healed  the  ulcers  by  its  use. 

The  combination  of  iodine  and  sulphate  of  copper,  which 
readily  unite  by  adding  a  litde  proof  spirit,  has  been  recom- 
mended by  Mr.  Norton,  and  administered  with  excellent  eflect 
in  doses  of  two  drachms  daily. 

To  sum  up  the  best  system  of  treatment  to  be  adopted  in  this 
disease,  it  should  first  be  repeated  that  there  are  but  few  coses 
in  which  the  symptoms  are  sufficiently  mild,  and  the  horse  of 
snfficient  value,  to  justify  the  expense  incurred  in  keeping  and

GLANDERS    AND    FAHCV.  233 

The  buds  are  sometimes  small,  about  the  size  of  a  shilling,  at 
other  times  as  large  as  a  hair  crown.  The  disease,  at  first,  is 
usually  confined  to  one  leg ;  but  as  it  progresses,  tlie  buds  appear 
in  various  parts  of  the  body,  and  as  they  approach  the  head  and 
throat,  the  symptoms  of  glanders  appear,  and  the  animal  soon 
sinks,  if  not  destroyed.  There  is  oilen  a  considerable  dropsical 
enlargement  of  the  leg  affected  in  farcy ;  and  sometimes  a  pecu- 
liar noise  is  heard  when  the  animal  walks,  as  if  the  joint-bones 
slipped  in  and  out  of  their  sockets.  Tliese  appearances,  par- 
ticularly the  tatter,  are  very  unfavourable,  and  the  horse  rarely 
recovers  when  it  is  present.  The  causes  of  farcy  are  similar  to 
to  those  of  glanders,  being  produced  either  by  contagion  or  other- 
wise although  it  may  be  justly  considered  that  it  is  much  less 
frequently  occasioned  by  contagion  than  glanders.  When  a 
number  of  horses  are  worked  hard,  fed  on  poor  or  unwholesome 
provender,  exposed  to  wet  and  cold,  or  closely  confined  in  an 
impure  atmosphere,  —  when  either  the  wliole  or  part  of  these 
causes  are  present,  farcy  will  very  probably  be  engendered. 
Mr.  Coleman  used  to  relate  in  his  lectures,  that  in  the  expedi- 
tion to  Quiberon,  the  horses  had  not  been  long  on  board  of  the 
transports  before  it  became  necessary  to  shut  down  the  hatch- 
ways ;  the  consequence  of  this  was,  that  the  horses  were  almost 
aufibcated  with  neat,  and  that  almost  all  of  them  disem- 
barked either  glandered  or  farcied.  When  farcy  thus  breaks 
out  in  an  establishment,  its  symptoms  are  generally  very  severe, 
and  its  course  rapid.  At  other  times  its  progress  is  slower,  but 
it  never  continues  for  years,  like  chronic  glanders. 

The  Treatment  must  be  very  similar  in  its  nature  to  that 
recommended  for  glanders,  but  with  a  much  greater  probability 
of  success.  The  system  must  be  supported  by  a  generous 
(though  not  too  stimulating)  diet,  and  the  vegetable  and  mineral 
tonics  administered  as  in  glanders;  but  if  the  sulphate  of  copper 
be  employed,  two  or  three  drachms  will  be  a  sufficiently  strong 
dose.  Carrots  or  green  food  will  form  a  useful  addition  to  the 
diet.  The  buds  should  be  opened  with  a  lancet,  and  when  the 
matter  is  evacuated  a  caustic  should  be  applied  to  the  ulcers. 
The  lunar  caustic  will  form  a  useful  application,  but  other 
caustics  may  be  em[>loyed.  An  ointment  composed  of  hydrio- 
date  of  potash  2  drachms,  lard  or  palm  oil  2  ounces,  mercurial 
ointment  2  ounces',  should  be  rubbed  daily  in  the  course  of  the 
enlarged  lymphatics.  The  horse  should  be  exercised  daily,  and 
properly  groomed,  and  the  above  treatment  continued  until  all 
symptoms  of  farcy  entirely  disappear.  It  must  be  confessed 
that  the  most  favourable  symptoms  often  prove  delusive;  for 
often  when   the  disease  appears  to  be  conquered,  it  will  break

nroid  the  troublesome  consequence  to  which  I  have  just  ail uded. 
It  must,  however,  be  materially  regul;iied  by  t)>e  state  and  con- 
dition of  the  hor^,  and  the  most  predominating  ca toe  of  the 
discos*'.  If  the  hor^e  he  in  full  condition,  we  eliouid  b)eed,  and 
that  very  freely,  {Nirlicnlarly  if  we  6nd,  as  we  usually  shall  Gnil, 
that  tlie  up]K-i'  surface  of  the  blood  ia  colouiless ;  when  this  H  the

it  sometimes  i»,  by  tliv  redundancy  of  moiKinre  in  his  food  (ibe

Jaiicel,  which  will  produce  great  relief,  particularly  if  the  leg  be

e,  we  may  insert  a  rowel  in  the  thigh.  If  abscesses  should 
a  in  the  thigh  or  leg,  we  must  take  care  to  distinguish  the 
:  from  farcy,  to  which  it  then  bears  a  resemblance ;  but  in 
latter  disease  the  abscesses  are  usually  smalier,  and  in  the 
ne  of  the  absorbents,  which  are  enlarged,  whilst  in  oedema 
f  are  larger  and  more  independent  in  their  position.  These 
eesaes  being  opened,  usually  heal  with  little  diflSculty ;  but  if 
skin  should  slough,  as  it  sometimes  does,  the  cure  is  much 
re  tedious.  There  is,  however,  a  difference  in  this  respect 
ween  the  human  and  the  equine  subject  j  for  whilst  in  the 
□er  the  cure  of  ulcers  is  tedious  and  protracted,  in  the  horse 
I  generally  accomplished  with  speed  and  safety. 

Veed. — There  is  a  disease  very  similar  to  oedema,  or  humour, 
t  ia  commonly  termed ;  but,  though  usually  confounded  with  it, 
■  yet  different  in  its  nature,  —  in  Scotland  it  is  termed  fVeed. 
e  horse  is  found  in  great  pain  in  one  of  the  hind  legs,  but  the 
lling  is  considerably  less  than  in  oedema,  and  is  situated  above 
hock  at  first,  from  whence  it  extends  downwards.  On  ex- 
ination,  we  find  a  swelling  in  the  course  of  the  tliigh  vein, 
ending  nearly  from  the  hock  to  the  groin,  very  hot,  and  ex- 
mely  tender  to  the  touch.  It  is,  in  fact,  a  local  inflammation 
the  lymphatic  vessels. 

rbe  treatment  consists  in  venesection,  purgatives,  and  diu- 
ics,  together  with  warm  fomentations  to  the  affected  part. 

'Jhapped  Heels.  —  Some  horses  are  so  predisposed  to  this  com- 
mt,  that  they  prove  a  source  of  great  annoyance  to  their 
aera  during  the  winter  months.  They  have  frequently  white 
s,  and  the  texture  of  the  skin  gives  way  from  the  least  ex- 
Dg  cause,  and  a  crack  takes  place,  which,  from  the  motion  of 
t  limb,  becomes  widened  and  deepened,  and  from  this  circum- 
Dce  is  often  exceedingly  difficult  to  heal.  It  is  usually 
iceded  and  accompanied  by  cedema  of  the  legs,  and  a  thin 
id  discharge  issues  from  the  wound,  and  from  the  irritation 
d  pain  produced  it  is  often  attended  with  considerable  lame- 
»  —  the  horse  catching  up  his  leg  in  a  peculiar  manner  on 
ng  moved. 

I^e  Treatment  should  consist  of  purgatives  and  diuretics, 
J,  if  the  system  be  plethoric,  venesection,  but  not  other- 
le.  The  heels  being  in  a  state  of  inflammation,  a  linseed 
nltice  should  be  applied  to  them  for  several  nights,  in  which 
>re  may  be  a  solution  of  alum  or  sulphate  of  zinc.  By  this 
idicaied  poultice  we  accomplish  two  purposes  at  the  same 
le  —  we  reduce  the  local  inflammation,  and  bring  about  the 
kitby  action  of  the  part,  by  the  stimulant  the  poultice  contains. 
it  scarcely  necessary  to  observe  that  the  heels  must  be  kept

with  much  liair  about  the  logs  arc  more  particularly  disposed  to

grease  is  usually  ml,  and  the  hair  appears  staring,  and  there  is 
BC  fii'st  considerable  pain  and  stifTiuft*  of  the  part.  After  a  whilf ,

the  same  time,  the  mflamnutioQ  of  the  heels  will  be  lessened. 
In  the  course  of  a  few  days  it  will  be  proper  to  discontinue  the 
poultices,  and  to  apply  the  astringent  lotion  alone.  If  the  dis- 
charge should  be  unusually  offensive,  a  little  solution  of  the 
chloride  of  lime  will  be  found  a  useful  adjunct  to  the  poultice. 

When  the  excrescences  called  grapes  have  formed,  the  only 
method  of  removing  them  is  by  casting  the  horse,  and  cutting 
them  off,  and  applying  a  caustic  to  the  sur&ce  afterwards.  This 
operation,  however,  should  not  be  practised  if  the  legs  are  con- 
siderably enlaised,  and  have  been  so  for  some  time,  nor  if  the 
grapes  are  so  thick  as  to  occupy  nearly  the  whole  of  the  surface, 
so  as  to  leave  little  or  no  sound  skin  between  them.  —  £d.] 

Bursavtee. 

[There  is  a  disease  peculiar  to  India  somewhat  resembling 
those  treated  of  in  this  chapter :  it  is  thus  described  in  the  ele- 
venth volume  of  the  Veterinarian,  by  Mr.  Armstrong :  — 

"  The  disease  *  Bursautee '  is  most  prevalent  in  July,  Au- 

Sust,  and  September,  which  are  the  wet  months;  and  thence  it 
erives  its  name,  *  a  disease  peculiar  to  the  rains.' 

"  Horses  of  every  breed,  age,  and  condition,  are  subject  to 
the  bursautee ;  but  the  second  generation  of  imported  horses 
are  most  liable  to  it  I  attribute  this  to  the  effect  which  climate 
has  in  weakening  the  constitution  of  the  horse ;  and  the  same 
thing  applies  to  all  animals  imported  into  that  country  from  a 
more  genial  temperature. 

*'  The  second  generation  is  still  worse  than  the  first. 

"  Nature  and  Causes.  —  I  trace  this  disease  to  the  change  which 
the  atmospheric  air  undergoes  at  this  season  of  the  year.  During 
the  three  previous  months  the  hot  winds  prevail. 

"  An  animal  exposed  to  the  parching  influence  of  this  air  is, 
u>  a  very  considerable  degree,  relieved  by  copious  perspiration 
from  every  part  of  his  frame;  and,  strange  as  it  may  appear,  the 
hot  season  is  remarkable  both  in  the  biped  and  quadruped  for 
the  absence  of  disease. 

"Then  comes  the  rainy,  or  wJiat  might  be  with  equal  pro- 
priety called  the  pestilential  season.  Land  storms,  hurricanes, 
soffocatiog  heat,  and  horrid  stenches  usher  in  this  awful  period. 
The  filth  of  ravines,  drains,  and  other  receptacles  of  putrid 
animal  and  vegetable  matter  becomes  saturated  with  rain,  and 
bebig  acted  upon  by  the  heat  already  in  the  soil,  generates  the 
most  noxious  gases,  which  speedily  mingle  with  the  circum- 
ambient air. 

*<  The  bursautee  is  an  eruption  all  over  the  body,  arising  from 
the  pores  of  the  skin  being  stimulated  by  the  increased  animal 
heat  to  discharge  the  perspirable  matter ;  but  this  is  prevented

I 


[Bkforc  we  proceed  to  its  diseases,  it  will  be  proper  to  notice 
briefly  the  structure  of  the  skin.  It  is  composed  of  three  sepo* 
rate  portions.  The  outer,  called  the  cuticle,  is  thin,  transpveni* 
and  insensible,  and  when  removed  is  quickly  restored  again. 
Tile  next  portion,  immediately  under  the  skin,  is  the  n-te- 
mueoaum,  being  a  sort  of  network  secreting  a  pigiurnt,  on  llic 
colour  of  which  depends  that  of  the  skin.  I1ie  internal  coat  is 
the  cutis  or  true  skin :  it  is  considerably  thicker  than  the  otbrr 
costs,  titough  its  thickness  varies  at  different  parts,  being  thiniter 
on  |be  inside  of  the  limbs  and  about  the  mouth  and  nostrils.  It 
uossesses  gri^t  tensibilily,  and  is  largely  supplied  with  ncrt'n. 
It  is  porous  in  its  siructure,  enabling  the  perspiration  to  post  out 
freely  ;  and  it  has,  by  the  sanic  nuvini',  a  ]iower  of  absorptioo, 
and  is  well  supplied  with  absorbents  as  well  as  otlwr  vessels.  It 
not  only  possess^  in  itself  a  high  degree  of  feeling,  but  abo  in-

timately  Bympatfauea  with  other  parts,  and  particularly  with  the 
stomach.  Its  sensibility  is  much  greater  than  the  parts  under- 
Death,  so  that  it  is  enabled  to  guard  tliem  from  danger.  It 
eives  support  to  the  roots  of  the  hairs,  which  are  found  towards 
it«  internal  surface;  thus  if  the  hairs  are  plucked  out  they  are 
soon  reproduced,  but  if  the  cutis  is  destroyed  the  roots  of  the 
hairs  are  so  likewise,  and  the  hair  does  not  again  appear,  as  the 
new  skin  is  incapable  of  producing  it.  The  growth  of  new  skin 
is  exceedingly  tedious,  as  it  only  grows  from  the  edges  of  the 
old.  It  is,  however,  greatly  assisted  by  the  great  extensibility 
poBsessed  by  the  old  £i»,  which  is  thus  enabled,  in  some  mea- 
sare,  to  cover  the  wound.  — ■  Ed.] 

Surfeit. 

This  is  a  disorder  of  the  skin,  consisting  of  small  tumours  or 
pimples  all  over  the  body,  which  become  small  scabs,  and  then 
gradually  get  well,  while  fresh  ones  continue  to  break  out  and 
pursue  the  same  course.  The  horse  has  generally  a  dry  un> 
healthy  coat,  and  is  hide-bound;  sometimes  there  is  swelling  of  the 
hindilegB  likewise,  and  general  debility.  Thisdisorderiscommonly 
produced  by  unwholesome  feeding  and  general  ill  treatment. 

[In  other  cases  the  affection  appears  in  horses  full  of  flesh,  in 
whom  it  is  usually  manifested  in  the  spring  or  early  summer 
months,  and  is  caused  by  plethora  or  a  redundancy  of  blood, 
which,  at  this  season  of  the  year,  is  most  likely  to  occur.  Some- 
times it  is  caused  by  a  draught  of  cold  water  in  hot  weather, 
and  is  then  often  preceded  by  shivering  and  a  staring  coat. 
The  symptoms  of  this  complaint  are  often  very  similar  to  the 
early  stages  of  mange,  and  require  much  discrimination  to  dis- 
tinguish the  difference. 

1  have  known  this  disease,  or  an  affection  similar  to  it,  appear 
periodically,  and  occasion  the  animal  to  be  denuded  of  hair,  in 
«[ute  of  every  thing  that  could  be  thought  of  to  prevent  it. 

Some  foreign  breeds  of  horses  are  much  disposed  to  cutaneous 
eruptions,  particularly  white  Turkish  horses. 

TVeoAizCTi^ -~- If  the  horse  is  in  a  plethoric  state,  or  in  full 
condition,  he  should  be  bled,  and  have  a  dose  of  physic ;  and, 
if  necessary,  the  following  alterative  may  be  al^erwtuxls  given. 
15  however,  the  animal  is  poor  and  out  of  condition,  the  blood- 
letting and  purging  should  be  abstained  from,  and  tlie  following 
alterative  given  dauy  for  several  days :  — 

Nitre 3  drs.

[Till*  disease  is  analogous  to  the  itch  in  the  buinan  subject. 
ati<)  U  one  of  lite  most  infectioua  diseases  to  which  llie  bonte  it 
liable. 

It  usually  commences  with  small  pimples  in  difTereiil  (tarts  of 
the  body,  which  burst  and  form  tcabs.  On  rubbing  off  these 
•etbs,  there  appear*  a  white  spot  coverf<l  by  a  thin  acrid  fluid, 
which  conlnins  \\iv  touive  of  inTeetion.  Tlu<«e  Mabs,  at  Grtl, 
are  conliiK'<l  to  ot»e  or  two  s|)ot!t,  but,  if  not  miiovfd,  gradually 
spread  over  the  body.  The  parts  most  fre<]ik'nily  nttacked  are 
the  withers,  the  roois  of  ihe  mane  and  tail,  and  tlw  rump  or 
butlnrk».  The  animal,  from  the  irritation  received,  rubs  off 
tlie  iicub,  and  llie  iicrid  fluid  spreads  and  forms  a  larger  soabi 
and  thus  denudes  tlic  afTfclfd  part  of  twir,  As  the  disease  pro- 
ceefb  the  greater  part  of  (lio  body  becomes  affected,  and  die

of  this  symptom  that  we  are  enabled  to  ascertain  the  progress  oF 
the  disease  towards  a  cure. 

The  nature  of  tliis  disease  has  been  found,  by  microscopic 
observation,  to  be  owing  to  ihe  presence  of  minute  insects  which 
have  been  denominated  acari.  Similar  insects  have  been  found 
in  the  itch  of  the  human  subject,  but  of  a  different  species.  It 
has  been  found  that  mange  can  be  communicated  to  the  human 
■ubject  and'  to  other  animals  from  the  horse,  although  by  no 
means  so  readily  as  between  animals  of  the  same  species.  A 
curious  experiment  was  tried  by  a  German  student,  a  few  years 
since,  by  taking  eight  horse  acari,  of  both  sexes,  and  confining 
them  to  his  arm  by  means  of  a  plaster.  In  a  few  minutes  they 
produced  a  great  itching,  which  continued  Rve  days;  but  Uie 
part  afterwards  got  well  of  its  own  accord.  Alter  the  lapse 
of  thirty-two  hours,  four  of  the  insects  had  disappeared ;  but 
there  were  found  several  eggs  and  small  passages  under  the  skin 
made  by  the  insect,  —  in  forming  which,  in  all  probability,  the 
itching  was  produced. 

This  disease  is  most  frequently  produced  by  contagion,  either 
by  direct  contact  with  a  mangy  horse,  or  by  rubbing  on  the 
root  where  a  diseased  horse  has  been  rubbing  himself  previously. 
Poverty,  also,  not  unfrequently  produces  it;  and  thus  it  is  often 
found  on  poor  commons  or  moors,  where,  however,  it  quickly 
spreads  from  one  horse  to  anotlier  by  contagion.  When  it  gets 
into  a  large  stable  of  horses,  it  is  difficult  to  eradicate  it,  in 
consequence  of  its  infectious  character,  and  the  greater  portion 
of  the  stud  will  probably  become  affected. 

The  treatment  of  this  disease  must  principally  consist  in  the 
topical  application  of  some  specific.  As  in  the  itch  of  the 
human  subject,  the  chief  remedy  should  be  sulphur,  which  is 
indeed  more  certain  than  any  other.  The  animal  should  be 
well  cleaned,  so  as  thoroughly  to  expose  the  sur&ce  of  the 
al&cted  parts,  and  the  following  liniment  rubbed  in  with  the 
hand  or^a  piece  of  flannel :  — 

Sulphur  vivum,  or  yellow  sulphur 4oz. 

Trwn,  linseed,  or  olive  oil l'2oz. 

Oil  of  turpentine 2oz. 

Mix. 

The  efScacy  of  the  above  may  be  greatly  assisted  by  substi* 
tuting  three  or  four  ounces  of  oil  of  tar  for  a  similar  quantity  of 
the  oil.  If  the  smell  of  train  oil  be  objected  to,  the  olive  oil  may 
be  substituted  in  stead ;  and,  if  necessary,  the  ointment  may  be 
coloured  according  to  that  of  the  horse.  If  black  or  brown,  a 
sufficient  quantity  of  soot  may  be  used  to  render  the  ointment 
black,  and  it  will,  at  the  same  time,  assist  its  efficacy,  for  soot 
has   been  found   of  great   assistance   in    this  disease.     If  the

Mallenders  is  a  disorder  titat  attacks  the  back  part,  or  flexurt, 
of  tbe  knee  joint,  and  depends  upon  a  combination  of  mange 
and  grease.  It  appears  as  a  scurfy  or  seabby  eruption,  and  is 
often  very  painful,  enu:'ing  some  degree  of  lameness  from  tbe 
pain  the  animal  fin-ls  in  moving  llie  joint.  Sometimes  it  is  not 
M>  contidenible  ns  to  pmdticc  lamencM,  or  any  apparent  incon- 
Tenience,  but  generally  liecomes  irouhlrtomc  and  obstinate 
unless  attended  to.  Sallenders  occurs  in  the  fore  pori,  or  flexure, 
of  the  bock  joint,  and  is  of  the  same  nature  as  mallenden. 
'Hiey  should  first  be  well  washed  with  soap  and  water,  and  all 
the  scurf  and  loose  cuticle  compleicly  removed.  They  may 
then  be  cured  by  the  following  ointments ;  —

These  are  of  the  same  nature  as  mallenders,  and  may  be  cured 
by  the  same  means.  They  generally,  however,  leave  a  blemish, 
consisting  in  a  lose  of  hair,  and  diickenlng  of  the  cuticle. 
Crown  scab  occurs  on  the  coronet,  and  rat  tails  in  lines  on  the

WARTS,  —  WENS.  —  ENCYSTED   TUMOURS. MELANOSIS. 

Warts  are  schirrous  excrescences,  which  appear  on  different  parts 
of  the  skin.  They  are  sometimes  very  large ;  at  others  small, 
but  very  numerous.  In  some  cases  the  roots  are  small,  in  others 
large,  and  involving  a  considerable  portion  of  the  skin.  Tlie 
flanks,  the  belly,  the  penis,  the  nose,  and  the  lips  are  the  most 
frequent  situations  of  warts.  If  not  too  extensive,  they  should 
be  excised  with  the  knife  or  the  hot  iron.  The  worst  situation 
for  warts  to  appear  is  the  penis,  the  extremity  of  which  is  some- 
times so  covered  with  them  as  to  produce  ^e^t  inconvenience,  and 
even  to  interrupt  the  passage  of  urine.  The  glans  penis,  in  had 
cases,  appears  quite  a  fungous  mass,  presenting  a  bleeding  and 
disgusting  appearance.  In  these  cases,  the  only  remedy  is  to 
amputate  the  penis  above  the  seat  of  disease. 

The  horse  being  cast  as  for  castration,  a  straight  staff  is  to  be 
rassed  up  the  urethra,  and  cut  down  upon  with  a  circular  incision. 
The  divided  arteries  may  be  closed  by  torsion  or  ligature. 

Mr.  Blaine  recommends  the  following  ointment  for  the  re- 
moval of  warts,  when  they  cannot  be  conveniently  removed  by 
the  knife :  — 

Muriate  of  ammonia 2  dr. 

Powdered  savin  1  oz. 

Lard 1^  oz. 

To  be  applied  once  a  day. 
The  success  of  this  ointment  is,  however,  doubtful ;  arsenic  is 
often  employed  with  greater  effect  in  the  form  of  an  ointmenL 

Wtnt  are  oval  or  round  bodies  found  in  various  parts  of  the 
body,  under  the  skin  generally,  in  a  detached  state.  They  are 
easily  removed  by  making  an  opening  with  a  knife. 

An  encysted  tumour  is  a  collection  of  fluid  within  a  mem- 
branous sac,  which  often  floats  loosely  under  the  integuments. 
It  must  be  cut  into,  and  dissected  out.

[MrlaitMU, 

Another  description  of  tumour,  appears  in  dtfTerent  psrta  of  tbe 
body.  I  lately  met  with  a  cww  in  a  while  AratMan  hone, 
belonging  to  a  di«ttn;;tiiK)M-d  nobleman,  in  whicli  the  tymptonu 
were  very  singiilnr  and  ol>s.(;«re. 

At  first  ihv  liorse  wiw  nitarkt-d  with  t|iiL<modie  pains;  Uii'D 
followed  wt'^kness  of  the  hind  quarters,  nhi<.-li,  lliouoh  slight  al 
finit,  gradually  incn^asod  until  lite  neck  of  the  bladder  was 
paralysed,  and  incapable  of  retaining  the  urine,  whicli  Howcil 
away  as  it  entered  the  bladder.  On  [ias»ing  my  hand  up  iIir 
rectum,  1  detected  a  large  tumour,  which  apfwurcd  lo  adhere  to 
the  spine,  and  which,  from  pressing  on  the  nerve*  of  tlio  hind 
extremities,  accounted  for  ihcir  partial  palsy.  'Hk'  animal  »a» 
destroyed,  and  the  tumour  was  found  of  gre«t  »\w,  not  oiilj 

tiresaing  on  the  nerves,  but  apjM-aiing  within  tlic  cavity  of  tbr 
arge  veiti,  the  vena  cava,  the  disposition  and  apitvaranoo  of 
which  it  had  completely  altered.  On  cutting  iiilo  the  tumour, 
it  was  found  to  be  melanosis,  a  disease  that  had  not  been  betbrc 
noticed  by  anv  English  vcirriuary  author. 

Melanosis  is  dorinod  by  I.acnnec  as  ''  a  patholt^ical  produc* 
tion  de|io»ited  ujion  the  KurfiKV,  or  in  tile  substaiict?  of  on 
organ,  of  a  durkiKli  or  blucki«h  colour,  having  no  analogy  with 
the  healthy  tissuvH  of  the  body."  The  disease  which  ww  de- 
scribed by  Brugnini  in  1781,  as  being  hereditarily  tramniitied 
among  the  horses  of  Chevuso,  and  whidt  lie  termed  Iietnur- 
rhoida,  was  evidently  melanosic;  it  wa«  usually  developed  around 
the  root  of  the  tail  and  the  anu«. 

Some  years  later,  in  1 7H4,  llie  same  disease  was  observed  at 
Drcsse  GoUety.  Latournelle  transmit  ted  an  account  of  it  in 
1800.  He  says,  "  there  supervened  in  a  young  kIrIUod,  on  the 
second  year  ol  his  covei-ing.  black  ^boutona,'  or  buds,  aroinul  the 
anus.  Tbey  soon  extended  to  the  scrotum  and  vliealli.  They 
were  placed  between  the  skin  and  muscles,  at  flmi  as  large  as  a 
Einiill  nut,  and  they  increased  until  ihey  attained  llie  sixe  of  a 
pullet's  egg ;  tliey  did  nut  suppurate,  and  were  insensible  in  the 


MELANOSIS.  S47 

too^  In  a  short  time  all  the  cellular  tissue  was  similarly 
a£&cted,  and  the  animal  died.  When  cut  into,  a  matter  like  the 
grease  of  a  cart  wheel  flowed  out.  All  the  progeny  of  this 
Btallion  which  had  the  same  colour  was  similarly  affected;  those 
which  were  black,  bay,  roan,  or  iron  grey,  escaped. 

In  1806,  Laennec  communicated  to  the  faculty  the  result  of 
his  observations  on  the  same  subject,  which  has  been  further 
elucidated  by  other  writers  since ;  but  much  still  remains  to  be 
done  for  iL  The  tumour  may  either  be  a  black,  opaque,  homo- 
geneous mass,  or  may  contain  a  darkish -coloured  fluid.  Crohier 
saw  a  tumour  of  the  kind  in  a  horse  weighing  thirty-six  pounds. 
The  opinions  of  most  writers  as  to  the  composition  of  the  mela- 
notic substance  agree  that  its  black  colour  is  owing  to  the 
presence  of  a  large  quantity  of  carbon.  Many  persons  are  of 
opinion  that  the  black  principle  is  an  aberration  of  the  pigment 
destined  by  nature  to  be  deposited  elsewhere,  as  the  rete  muco- 
8um,  the  choroid,  the  hair.  It  is  said  that  persons  with  light 
hair,  and  elderly  persons  whose  hair  is  white,  as  well  as  light 
grej  or  white  horses,  are  most  commonly  the  subjects  of  this 
disease.  This  opinion  is  certainly  supported  by  the  case  related 
by  me,  the  horse  being  a  white  Arabian.  He  had  one  tumour 
only  externally  perceptible,  which  was  about  the  size  of  a 
walnut,  and  had  existed  for  some  years ;  but  he  had  an  immense 
number  deeper  seated  in  various  parts  of  the  body.  It  will  be 
an  interesting  subject  for  future  observation  to  ascertain  whether, 
and  to  what  extent,  his  progeny  are  effected ;  because,  if  they 
really  become  affected  to  any  extent,  it  will  offer  a  strong 
objection  to  the  use  of  these  white  horses  as  stallions.  Lec- 
turers and  writers  have  but  little  to  say  on  the  treatment  of 
the  disease,  and  that  little  not  very  satisfactory.  It  appears  to 
me  that,  amongst  our  remedial  agents,  the  use  of  iodine  demands 
some  attention. 

Melanosis  appears  to  be  a  much  more  common  disease  in 
India  than  in  this  country.  In  April,  1840,  Mr.  Jackson,  of 
the  East  India  service,  communicated  the  following  paper  on 
the  subject  to  the  Veterinarian  .■  —  "I  was  pleased  to  find  that 
the  conclusion  I  had  come  to  in  my  own  mind  as  to  the  identity 
of  the  disease  common  among  horses  in  Ir)dia,  known  by  the 
name  of  *  diseased  tail,'  with  *  melanosis '  in  the  human  subject, 
was  confirmed  by  your  intelligent  correspondent,  Mr.  W.  C. 
Spooner.  The  disease,  as  described  at  pages  163  and  164.  of 
this  journal,  is  very  common  about  Madras,  but  in  most  cases  is 
confined  externally  to  the  tail,  which  is  occasionally  enormously 
enlai^ed.  I  have  seen  tumours  round  the  anus,  and  in  various 
parts  of  the  body.  Light  grey  horses  are  most  subject  to  it, 
and  of  that  colour  those  with  curly  manes  and  tails.  I  have 
never  had  an  opportunttv  of  making  a  post  mortem  examination;

and  secretes  u  muoous  lliit<I,  as  well  as  the  hairs,  tiamt'd  cilia,  or 
ej-elsshee.  In  the  horse  there  ia  only  one  eyelash,  iliai  is,  the 
superior,  which  serves  to  keep  out  dust  from  the  eye,  and  inodo-

any  impediment  to  the  reflected  light  which  comes  from  the 
sur&ce  of  the  earth.     Immediately  under  the  Buperior  part  of 
the  orbit,  or  socket  of  the  eye,  and  rather  towards  the  inner 
corner,  there  is  a  gtand  of  considerable  size,  which  forms  the 
fluid  named  tears.     This  fluid  is  conveyed  lo  the  under  surface 
of  the  upper  eyelid,  and  is  then  diffused  all  over  ihe  eyp,  by  the 
motion  of  the  lids,  as  well  as  by  the  motion   of  the  eye  itself. 
Id  this  action  the  upper  eyelid   is  principally  employed.     As 
the  tears  accumulate,  they  are  directed,  by  the  closing  of  the 
eyelids,  towards  the  inner  corner,  where  they  are  rix;eived  by 
the  open  extremities  of  two  ducts,  which,  soon  uniting,  form  liie 
lachrymal  duct,  a  long  membranous  tube  which  terminiites  in 
the  lower  part  of  the  nostril,  where  it  may  be  distinctly  seen, 
with  the  fluid  nimied  tears  flowing  from  it.     The  inner  surface 
of  the  eyelids  is  formed  by  the  membrane  named  conjunctiva, 
which,  passing  inward,  embraces  the  globe  of  the  eye,  and  scrvea 
to  keep  it  in  its  situation ;  at  the  same  time  it  is  sufficiently  loose 
to  admit  readily  of  all  its  various  motions.     This  membrane,  tn 
its  healthy  state,  is  nearly  white;   but  in  all  cases  of  internal 
inflammation,  or  inflammatory  fever,  becomes  very  red.     In 
staggers,  and  some  other  disorders  of  tlie  stomach,  and  organs 
subservient  to  digestion,  it  becomes  of  a  deep  yellow  or  orange 
colour.     This  membrane  is  closely  united  to  nearly  one  half  of 
the  sclerotic  coat,  or  white  of  the  eye,  and  has  been  thought  to 
be  continued  in  a  very  attenuated  and  transparent  state  over  the 
cornea  also.     In  injuries  of  the  eye,    ibis  membrane  Iiecomes 
red ;  but,  in  internal  diseases,  it  should  always  bo  examined,  as 
redness  in  that  case  indicates  general  inflammatory  action,  and 
points  out  the  necessity  of  copious  bleeding.     In    the   inner 
corner  of  the   eye   there   is  a  small   fleshy  eminence,  named 
caruncle,  which  separates  the  two  open  extremities  of  the  lachry- 
mal ducts,  named  puncta  lachrymaJia,  and  thus  allows  the  tears 
to  be  forced  into  them  by  the  contraction  of  the  orbicular  muscle. 
In  the  human  eye,  the  tears  pass  from  the  puncta  lachrymatia 
into  a  small  bladder  or  sac,  which  do<'S  not  exist  in  the  horse; 
in  him  there  is  one  continued  membranous  tube  from  the  inner 
comer  of  the  eye  to  the  lower  part  of  the  nostril.     The  termi- 
nation of  tlie  lachrymal  talte,  or  duct,  in  the  horse,  has  often 
been  mistaken  for  an  ulcer  in  horses  suspected  of  glanders;  but 
it  does  sometimes  become  ulcerated  from  the  acrimony  of  the 
tears,  or  from  the  strong  preparations  that  are  sometimes  ap- 
plied in  diseases  of  the  eye.     I  have  seen  this  happen  from  the 
application  of  powdered  sal  ammoniac  (muriate  of  ammonia)  to 
the  eye.    Sometimes  the  termination,  or  orifice,  of  the  lachrymal 
doct  becomes  closed  by  inflammation,  or  the  cicatrisation  of  an 
ulcer,  and  then  it  bursts  above,  and  the  ruptured  part  becomes 
aD    idcer.     According  to    Lafosse,   the   disease  named   fistula

lachrymalis  takes  place  in  the  horse;  but  of  tliia  1  hnTCSwn 
onl^  one  case.  In  glanders,  howpver,  ihrre  i»  often,  indtvd 
generallyi  a  slight  purulent  or  mticous  di.ichargc  from  tlie  iiiiiet 
corner  of  the  eye,  whit-h  probably  procee<i*  from  ilic  Incltrynial 
duct.  Tl>c  membmna  niclilans,  or  huw,  m  it  w  rninmoul]^ 
luuDcd,  is  citiinicHl  in  the  inner  cnnier  of  the  eye.  'I'liat  pMt 
wliicti  coiiii-:!  oviT  ihc  eye  is  a  thin  ulippery  meiiibratie,  which, 
towards  it*  1><'Mij>,  U-eonn-*  thicker,  and  cartiln^finoua.  Its  baw 
is  of  M>mc  til ick new,  mid  imbf<ldMt  in  fat;  there  are  no  muscln 
atlaclied  to  it;  but  when  ttiv  eye  iti  drawn  into  the  orbit,  and 
towards  the  inner  comer,  the  hluis  of  the  tiaw  is  prevented  from 
following  it  by  the  bone«  of  the  orbit;  the  thin  mcmbraoous 
port  of  the  ba»  is  thus  forced  over  the  eye,  ami  eerve^  to  re- 
move dust  or  dies  that  may  have  fallen  upont-hc-  corni>a. 

The  rye  is  moved  by  seven  muscles,  nliicli  urisv  from  within 
tbe  orbit,  or  socket,  and  terminate  in  thin  »))M.-ts  of  tendon, 
which,  with  tlie  sclerotic  coal  and  conjunctiva,  form  what  it 
called  the  while  of  ilic  eye.  Of  iliosc  there  are  four  s(raif>lit 
muscle*  rintnj;  from  the  bottom  of  the  orbil,  and  insertpd  into 
the  ontt-r  coat  of  the  eye.  One  of  them  it  utuatH  at  the  iipi>rr, 
one  on  the  under,  nntl  one  on  each  side.  Their  use  i.i  ftppnrcnt : 
ftciing  simultaneously  they  pull  the  eyr  within  the  ortiit;  and 
acting  M^aralcly  ihey  draw  It«  tmntiMirent  surface  to  one  tide 
or  tbe  other,  upward  or  downward,  according  to  the  situation  of 
the  acting  muscle.  Itc«!dvi  these,  there  are  two  obliqtre  musdn, 
the  superior  and  ttie  inferior;  t)M-  former  rises  from  the  back  of 
llteorbil,  gnrti  to  (hi.-  iiin<-r  »ide,  where  it  paimi<4  through  a  pullty; 
its  tendon  then  triiversi^  tn  an  oppofitc  direction,  and  is  in- 
serted into  t]ie  upper  atid  outer  piirt  of  tlie  eye.  'i1>e  inferior 
is  a  shorter  and  stronger  muscle,  but,  like  the  former,  to  which 
it  is  an  antagonist,  takes  an  oblique  course.  These  muscles 
funiish,  in  some  measure,  a  rotatory  motion  to  the  eye,  and  tliiia 
giving  expre^ion  to  these  organs,  are  exercised  particularly  ill 
viciouN  hor»o«.  11)e  seventh  muscle,  which  is  peculiar  to  brute», 
is  called  ilw  retractor,  and  is  situated  within  the  atraiglit 
muscles,  and  imini-<)iatcly  surrounds  the  optic  nerve.  Its  use  is 
to  draw  the  eye  farther  into  Oic  orbit,  and  by  pressing  on  dte 
fat,  which  formii  a  toh  cuibion  for  this  organ,  forces  the  haw  to 
protrude  itself  more  readily  over  it.  Tliis  muscle  poueeeee  con- 
nderable  jwwcr. 

Having  de.icribed  ihe  n]i[H-ndage«,  as  they  itn:  termed,  I  &hn)l 
proceed  to  a  description  of  the  eye  itselli  the  structure  and 
economy  of  which  is  most  curiou«  and  inirresting.  It  is  said  to 
be  composed  of  coats  and  hnmours,  and  thin,  perhnps,  is  tlie  bnil 
manner  of  cooBideriiig  it.  'lite  firi!t  com!  that  appears  n  tlie 
cornea,  or  glass  of  the  eye,  which  fonit;  the  inilerior  [lart,  and

of  the  eye,  beiae  that  part  of  the  caee  formed  to  admit  light.  It 
is  not  of  a  circular  form,  as  in  man,  but  of  en  irregular  oval  or 
rather  ohlong  form  when  examined  out  of  the  socket ;  but  in  its 
natural  situation  in  the  living  horse,  that  part  which  projects 
beyond  the  eyelids  is  a  regular  oval,  or  rather  of  an  oblong 
form,  and  corresponding,  in  some  degree,  with  the  form  of  the 
popil.  It  forms  a  larger  portion  of  the  globe  of  the  eye  than  in 
man,  and,  by  its  convexity,  causes  the  rays  of  light  which  pass 
through  it  to  converge  towards  the  pupil.  This  convexity  may 
be  too  great  or  too  little,  and,  in  either  case,  render  vision  some- 
what imperfect,  and  cause  starting.  The  convexity  of  the  cornea 
is  preserved  by  the  fluid  which  it  incloses,  named  aqueout 
hvanoar.  On  puncturing  the  cornea  this  fluid  escapes,  and  then 
the  cornea  becomes  flat  and  wrinkled. 

The  second  humour  of  the  eye  is  situated  immediately  behind 
the  pupil,  and  b  named  the  crystalline  humour,  or  crysiaDine 
lens.  On  taking  it  out,  it  appears  to  be  a  solid  and  beautifully 
transparent  double  convex  lens,  the  posterior  surface  of  which  is 
more  convex  than  the  anterior  one.  It  is  found  to  become 
denser  and  denser  from  the  circumference  to  the  centre;  and 
the]  slightest  pressure  so  deranges  it,  as  to  lessen  or  destroy  its 
transparency. 

The  crystalline  humour  may  be  considered  as  composed  of 
numerous  concavo-convex  lenses,  admirably  fitted  to  each  other ; 
those  of  the  largest  size  having  their  circumference  or  edge  op- 
posed to  and  nicely  joined  to  each  other,  thus  forming  altogether 
a  double  convex  lens.  The  point  of  union  between  the  two 
largest  lenses  is  embraced  by  a  band  of  muscular  fibres,  disposed 
in  a  circular  direction,  and  named  the  ciliary  ligament.  These, 
by  contracting,  assisted  probably  by  the  muscles  of  the  eye,  in- 
crease the  convexity  of  the  crystalline  lens,  or  rather  of  the 
series  of  concavo-convex  lenses  of  which  the  eye  is  composed,  in 
a  manner  so  just  and  equal,  as  to  adapt  it  to  the  distance  of  the 
object  at  which  the  animal  is  looking:  while,  by  the  relaxation 
of  these  muscular  fibres,  the  convexity  of  the  lens  is  diminished 
by  its  own  elasticity.  These  changes  take  place  with  incon- 
ceivable rapidity  and  accuracy.  There  are  other  muscular  fibres 
proceeding  from  the  band  of  circular  fibres  named  ciliary  pro- 
ceases  in  a  straight,  or  rather  radiated  direction,  towards  die 
second  coat  of  the  eye,  named  tunica  choroides;  these  are  so 
arranged  as  to  be  drawn  into  folds,  by  which  disposition  they  are 
enabled  to  perform  their  office  more  easily,  which  is  that  of 
drawing  the  lens  towards  the  optic  nerve,  and  thereby  increasing 
the  intensity  of  vision,  whereby  the  animal  is  enabled  to  see  small 
objects  distinctly.  The  crystalline  lens  is  enclosed  in  a  trans- 
parent capsule,  which  is  not  in  contact  with  it,  there  being  about 
one  drop,  as  it  is  computed,  of  a  transparent  liquid  interposed

>er\'cd  in  iIh>  circular  fibres  of  the  iris,  causing  tbc  pupil  to  be 
small,  even  in  n  nioderatv  ligbl,  while  th«  inflammation  is  going

CContinually  exposed  to  a  changing  light,  —  sometimes  to  the 
glare  of  a  summer's  sun,  at  ntliem  to  the  chastened  light  of  the 
moon  or  stars, — the  eye  would  be  of  little  use,  unless  it  [Mwscfied 
tl>e  )x>wcr  of  nhuttiiig  out  too  great  a  glare,  or  of  admitting  the 
utmost  during  the  hours  of  darkitew,  or  in  tlie  grey  twilight. 
litis  power  ia  furnislted  by  the  iris  or  curtain  of  tne  eye,  which 
commenoes  at  the  same  place  where  the  cornea  b^ins,  and 
floats  loosely  in  the  aqueous  humour,  which  it  divides  into  two 
parts,  tlie  anterior  and  tl>e  posterior  clianibcrs.  The  irb  \s

with  tlte  rvtina,  to  as  to  lessen  iIk'  pupil  from  tbo  stimulus  of 
light. 

Thi«  may  be  readily  seen  in  the  horse  by  alternately  shading

On  Vitiott. 

[Before  we  enter  on  the  dttewn  of  lite  eyo^  it  would  be  wrii 
to  notice  briefly  the  phenomena  of  vision. 

A  ray  of  li^hi,  whtru  it  iinpiriges  oti  a  both',  is  subject  nlluf 
to  reflection,  nb^orptiou,  or  transmission.  If  reflectecl,  it  recoils 
from  the  surface  of  the  object  which  it  cannot  pemicate,  in  tlte 
same  manner  as  a  ball  would  rebound  if  thrown  against  a  wall. 
Each  ray  of  light  is  composed  of  6e^■e^  colours,  wliich  n»y, 
indt-ed,  be  8ciiaraied  by  a  triangular  piece  of  f^Loss,  called  a 
prisnit  ajid  different  obji-cf  have  tlie  power  of  u^Morbing  some 
of  these  coloun  and  reflecting  othen.  The  coluim  absorbed 
are,  of  counie,  retidentl  invisible,  aitd  those  reflected  are  seen ; 
and  ihtts  it  is  oecording  to  the  colour  or  colour*  reflected  tl<al 
an  object  apjtean  j;reeti|  or  blue,  or  yellow.  When  it  appears 
white  all  the  colours  are  teftected,  aivd  when  black  they  are  all 
absorbed. 

It  is  a  taw  of  optics  tlial  the  angle  of  reflection  and  that  of 
incidence  are  equal.  I'he  former  signifies  the  dir(y;uon  in 
which  the  object  or  ray  strikes  a  mirror,  and  tlM'  latter  ihv  angle 
at  which  it  may  be  seen.  They  may  be  repr<-«etited  by  two  per- 
sons standing  at  an  ct|ual  inclination  from  a  mirror  in  whtdi 
they  may  be  "ble  to  see  each  other's  imago,  thonj^h  not  suf- 
ficiently op)MMite  as  to  discern  their  own.     It  is  found  tliat  iIk- 


THE    8TBDCTUB£    AND    FUNCTIONS   OF   THE    EYE.  257 

degree  of  reflection  depends  on  the  degree  of  obliquity  with 
which  the  ray  impinges  on  the  surface  of  the  reflecting  object, 
and  thus  the  reflected  Jight  of  the  sun  and  moon  is  greatest 
when  rising  or  setting. 

All  bodies  have  the  power  of  absorbing  rays  of  light,  but  in 
different  degrees.  Opaque  bodies  absorb  more  light  tlian  trans- 
parent ones;  and  of  these  black  substances  absorb  most,  and 
white  in  the  least  degree. 

When  a  ray  of  light  enters  a  transparent  medium  of  greater 
density  than  what  it  has  just  left,  it  becomes  refracted  or  turned 
from  the  perpendicular ;  and  when  the  density  is  less  than  before, 
it  appears  refracted  towards  the  perpendicular.  Thus,  when  a 
stick  is  plunged  into  water,  it  appears  broken  at  the  surface  of 
the  liquid,  which  is  owing  to  the  rays  of  light  being  broken  as 
they  pass  from  the  object  into  the  air.  S0|  likewise,  when  a 
ray  of  light  impinges  on  a  curved  surface  it  is  refracted;  and 
thus  a  dense  transparent  body,  of  a  convex  figure,  will  collect 
the  rays  into  one  common  point  or  focus,  whicn  may  be  shown 
by  the  common  burning-glass.  Concave  lenses  have  a  contrary 
effect,  causing  the  rays  to  diverge. 

The  axis  of  a  convex  lens  is  exactly  perpendicular  to  its  two 
surfaces,  and  this,  in  a  double  convex  lens,  passes  through  the 
centre ;  and  when  a  ray  of  light  comes  in  this  direction,  it  passes 
directly  through  without  any  refraction ;  but  an  oblique  ray  is 
turned  inwards,  so  as  to  form  a  focal  point  with  a  ray  coming  in 
a  similar  manner  from  the  other  side. 

These  being  the  principal  laws  by  which  vision  is  governed, 
we  are  enabU^  to  understand  the  distinct  offices  of  the  various 
parts  of  the  eye. 

The  tranxpmrent  cornea,  the  window  of  the  eye,  serves  to  collect 
the  rays,  and,  by  its  convexity,  to  refract  them  towards  the 
ocular  axis. 

The  aqueous  kumotir,  besides  its  office  of  preserving  the  con- 
vexity of^  the  cornea  and  allowing  the  iris  to  float  loosely  amidst 
it,  serves  likewise  to  refract  the  rays,  from  its  being  a  denser 
medium  than  the  atmosphere. 

Tlie  ayttaUine  lens,  however,  is  the  principal  refracting  glass; 
receiving  the  rays  in  some  measure  retracted  by  the  cornea  and 
aqueous  humour,  it  brings  them  to  a  focus  on  the  retina. 

When  either  the  cornea  or  the  crystalline  lens  is  too  convex, 
the  object  is  brought  to  a  focus  too  soon,  and  vision  is  indistinct, 
and  the  person  near-sighted.  This  is,  probably,  a  frequent 
defect  in  the  eyes  of  horses  that  shy,  in  which  we  often  find 
full  gt^le  eyes.  When,  however,  the  cornea  or  the  lens  is  too 
flat,  a  contrary  defect  is  produced,  and  the  object  is  not  converged 
soon  enough.     This  is  a  frequent  compUint  in  old  people,  who

This  disease  arises  from  some  external  injury,  such  as  a  blotr 
from  a  stick  or  whip,  a  bite  from  another  horse,  or  tbe  intniiiion 
of  some  foreign  binly.  It  is  inijwriant  to  distinguish  ibis  dis- 
ease front  that  we  bavR  presently  to  notice,  which  mav  be  done 
without  much  difficulty,  by  an  attention  to  the  following  symp- 
tom*. Unless  tbe  injury  i.t  very  triflinji^  there  is  iisual^  much 
swcllin)j(  and  inflammation  of  the  eyeltdi  and  its  envelopments- 
Shortly  afienrards  we  find  an  opacity  of  tin*  trani'[>arciit  cornea; 
this  opacity  rarely  spreafb  over  lite  whole  of  tlic  eyis  but  is 
much  greater  at  one  part  than  anotlier.  On  iitspeclitig  the 
eye  in  a  lateral  position,  we  find  that  the  aqueous  humour  is 
either  not  affected,  or  only  partially  »o ;  and  on  looking  into  tbe 
interior  of  tbe  rye,  wc  find  the  parts  presenting  a  hvaltlty  ap- 
pearance.

to  occasion  blindness,  or  otherwise  to  be  pennanently  fixed  in 
one  part,  so  as  to  obstruct  vision  and  defy  all  our  attempts  for  its 
removal.  When  the  inflammation  is  considenvble  we  should 
lance  the  inflamed  vessels  of  the  eyelid,  and  encourage  the  bleed- 
ing as  much  as  possible,  and  at  the  same  time  open  the  angular 
Tein  which  passes  from  the  eye  down  the  face.  In  performing 
this  operation  it  is  necessary  to  cut  in  some  measure  across  the 
vein,  in  order  to  ensure  its  bleeding  freely.  If  the  blood  should 
not  flow  &eeljS  it  will  be  better  to  bleed  from  the  neck  at  the 
same  time.  'Ilie  eye  should  be  frequently  fomented  with  warm 
water  the  first  day,  and  af^rwards  the  following  lotion  should  be 
applied  round  and  in  the  eye  six  or  eight  times  a  day :  — 

Cold  water 1  pint. 

Tincture  of  opium 1  ounce. 

A  dose  of  physic  should  be  given ;  and  if,  in  a  day  or  two, 
there  be  still  much  inflammation,  a  few  quarts  of  blood  may  be 
taken  from  the  neck  of  the  afiected  side.  When  the  inflamma- 
tion has  in  great  measure  abated,  but  a  film  or  opacity  remains 
on  the  cornea,  a  few  drops  of  the  following  stimulant  should 
be  applied  twice  a  day  with  a  camel's  hmr  brush :  — 

Distilled  water 1  ounce. 

Nitrate  of  silver 1  or  2  grains. 

Or  instead  of  this,  a  little  vinumopii,  or  tincture  of  opium  diluted 
with  an  equal  quantity  of  water. — Ed.J 

Specific  Ophthalmia,  or  Inflammatimi  of  the  Eye. 

[This  disease  used  to  be  called  by  farriers  moon  blindness, 
nnder  the  idea  that  its  periodical  attacks  were  influenced  by  the 
moon,  as  it  some^mes  occurs  about  once  a  month.  This  idea, 
however,  is  altogether  absurd,  and  its  periodical  returns  are 
rarely  so  frequent  as  once  a  month.  The  disease  consists  of  a 
specific  inflammation  of  the  various  parts  of  the  eye  occurring 
without  any  immediate  external  cause;  and  though  in  great 
measure  curable  for  the  time,  yet  occurring  again  and  agmn, 
nntil  tlie  structure  of  the  eye  is  so  changed  by  these  re- 
peated attacks,  that  blindness  follows,  or  otherwise  a  cataract 
takes  plac^  either  total  or  partial. 

The  tymptonu  generally  appear  somewhat  suddenly ;  in  the 
evening,  perhaps,  there  might  have  been  nothing  amiss,  but  on 
the  following  morning  sometimes  both  eyes,  but  usually  one  eye 
only  is  found  nearly  closed  and  suffused  with  tears ;  there  is 
great  impatience  of  light,  and  indeed  it  is  somewhat  diflScult  to 
induce  the  animal  to  open  the  lids  sufficiently  for  examination, 
and  when  be  does  so,  the  pupil  is  found  exceedingly  small,  so

inclosed  in  one  delicate  transparent  membrane,  named  tunica 
aracliiioidea.  If  the  vitreous  humour  is  cut,  by  snipping  it  with 
scissors,  a  fluid,  like  water,  drops  from  il  freely,  so  that  it  ap- 
poari  to  be  nothing  more  than  wnicr,  proliably  hultling  a  tittle

termed,  the  arachnoid  coat  may  be  inflated  with  a  small  blow- 
pijic,  and  made  to  resemble  a  circular  canal;  this  has  been 
c<dl»l,  from  the  name  of  the  person  wlio  first  ob<er\'ed  it,  llie 
ciivular  canal  of  Petit.  It  is  supposed  to  be  conncicicd  with  the 
radiated  fibres  of  the  iri*.  I  have  seen  the  whole  of  iliis  humour 
in  the  eye  ofa  !>heep  that  li-iil  an  hydatid  in  the  right  ventricle 
of  the  brain  of  the  couiistenei-  of  jelly. 

[The  retina  is  a  tine  <letieaie  triin.iparent  iiK'inbrane,  on  which 
a  picture  of  external  objects  is  painted.     It  is  ^rend  out  on  ilio

back  part  of  the  vitreous  humour,  and  has  the  choroid  coat  im- 
mediately beliind,  which  therefore  acts  like  the  quicksilver  of  a 
looking-glass  in  preventing  the  light  from  passing  through.  The 
retina  is  supposed  to  be  a  continuation  of  the  optic  nerve. 

The  choroid  coat,  whose  use  has  been  specified,  appears  to  be  a 
net-work  of  blood-vessels,  secreting  a  dark  paint  on  both  its  sur- 
&ces.  It  is  analogous  to  the  rete-uiucosum  of  the  skin,  and  in  the 
human  subject  is  quite  black,  being  that  which  gives  the  colour 
to  tlie  pupil  of  the  eye.  In  animals,  however,  we  observe  a 
great  variety  in  the  colour  of  that  portion  of  it  immediately  op- 
posite the  pupil,  or  at  the  back  of  the  eye,  being  in  the  cat  of  a 
yellow  colour,  and  in  the  horse  of  a  greenish  blue.  The  light 
colour  of  this  part  serves  to  reflect  some  portion  of  the  light  ad- 
mitted ta  the  eye,  and  thus  economises  and  renders  available  the 
partial  light  that  is  always  present  even  in  the  darkest  night 
and  thus  it  is  that  a  horse  is  enabled  to  pick  his  way  with  ease 
when  his  rider  is  unable  to  distinguish  a  single  object.  The 
portion  of  the  choroid  coat  which  accomplishes  this  effect  is 
termed  the  tapetum  iucidum,  or  luminous  carpet.  —  Ed.] 

The  last  and  most  considerable  coat  of  the  eye  is  the  sclerotic 
coat,  which  is  a  very  strong,  thick,  white,  and  opaque  membrane) 
including  all  the  other  coats  and  humours,  except  the  cornea. 
The  sclerotic  coat  forms  the  greater  portion  of  the  globe  of  the 
eye,  and  is  intimately  united,  towards  the  anterior  part,  with  the 
rornea,  which  may  be  viewed  as  bearing  the  same  relation  to  the 
iclerotic  coat  as  the  glass  of  a  watch  does  to  the  case.  By  ma- 
ceration in  water  the  cornea  separates  from  the  sclerotic  coat 
completely. 

The  optic  nerve  penetrates  the  posterior  part  of  the  eye,  not 
in  the  centre,  but  rather  inwardly:  still,  however,  it  is  central 
with  respect  to  the  axis  of  vision,  for  both  eyes  are  always  ex- 
erted in  looking  at  objects,  and,  in  doing  this,  incline  a  little 
inwardly,  so  as  to  make  the  optic  nerve  central  with  respect  to 
the  object,  or  rather  as  to  the  axis  of  vision. 

Anatomists  have  supposed  that,  were  this  the  case,  the  insertion 
of  the  optic  nerve  would  cause  a  dark  spot  to  appear  before  the 
eye,  ana  that  the  nerve,  therefore,  enters  a  little  inwardly.  But 
this  is  an  error,  as  has  been  demonstrated  by  the  experiment  of 
tbe  late  Dr.  Darwin,  in  which,  after  looking  at  a  coloured  object 
stedfastly  for  some  time,  upon  shutting  the  eyes  the  impression 
will  remain  a  considerable  time,  and  in  an  equal  degree  upon 
the  insertion  of  the  optic  nerve,  and  every  part  of  the  retina, 
without  the  appearance  of  any  dark  spot  wnatever.  This  not 
only  proves  that  that  part  of  the  optic  nerve  which  enters  the 
sclerotic  coat,  and  from  which  the  retina  proceeds,  is  susceptible 
of  the  impressions  of  light  in  the  same  degree  as  the  retina ;  but 
that  the  vitreous  humour,  or  rather  its  arachnoid  membrane,

Oh  t'ision. 

[Before  wp  enter  on  the  di«casn  of  the  eyp,  it  would  be  wt-II 
to  notice  briefly  the  phenomena  of  vision. 

A  ray  of  ii^ht,  when  ii  impinges  on  11  body,  is  Hubject  either 
to  reflection,  absorption,  or  tranMnitaion.  11  rcflecte<l,  it  recoili 
from  the  surfiiee  of  tbc  olm-ct  which  it  cannot  permittte,  in  tlie 
Munc  manner  as  a  ball  would  rcbouikd  if  thrown  sgniii»t  a  wall. 
Each  ray  of  light  is  compoitxl  of  seven  colours,  which  may. 
indeed,  be  aeparated  by  a  ti'iangular  piece  of  glass,  called  a 
prism,  and  different  objecls  have  lite  power  of  absorbing  some 
of  these  colours  and  reflecting  others.  The  colours  absorbed 
are,  of  course,  rendered  invisible,  and  tltusv  roflt-ctcd  are  seen ; 
nod  thus  it  is  according  to  llic  colour  or  colours  reflected  thai

incidence  are  equal.  The  former  aignifiee  the  direction  iu 
which  tbe  object  or  my  atrikea  a  minoi-,  and  the  Latter  the  aiiglc 
at  which  ii  may  be  seen.  Tliey  may  be  representwl  by  two  u-r* 
sons  standing  at  an  equal  inclination  from  a  mirror  in  wliicb 
they  may  be  able  to  see  each  oilur's  image,  iWngh  not  luf- 
lieiently  opposite  as  to  flisoem  their  own.     Il  ix  Ibund  that  (he

degree  of  reflection  depends  on  the  degree  of  obliquity  with 
which  the  ray  impinges  on  the  surface  of  the  reflecting  object, 
and  thus  the  reflected  light  of  the  sun  and  nu)on  is  greatest 
when  rising  or  setting. 

All  bodies  hare  the  power  of  absorbing  rays  of  light,  but  in 
different  degrees.  Opaque  bodies  absorb  more  light  than  trans- 
parent ones;  and  of  these  black  subsunces  absorb  most,  and 
white  in  the  least  degree. 

When  a  ray  of  light  enters  a  transparent  medium  of  greater 
density  than  what  it  nas  just  lef^  it  becomes  refracted  or  turned 
from  the  perpendicular,-  and  when  the  density  is  less  than  before, 
it  appears  refracted  towards  the  perpendicular.  Thus,  when  a 
stick  is  plunged  into  water,  it  appears  broken  at  the  surface  of 
the  liquid,  which  is  owing  to  the  rays  of  light  being  broken  as 
they  pass  from  the  object  into  the  air.  So,  likewise,  when  a 
ray  of  light  impinges  on  a  curved  surface  it  is  refracted ;  and 
thus  a  dense  transparent  body,  of  a  convex  figure,  will  collect 
the  rays  into  one  common  point  or  focus,  which  may  be  shown 
by  the  common  burning-glass.  Concave  lenses  have  a  contrary 
effect,  causing  the  rays  to  diverge. 

The  axis  of  a  convex  lens  is  exactly  perpendicular  to  its  two 
surfaces,  and  this,  in  a  double  convex  lens,  passes  through  the 
centre ;  and  when  a  ray  of  light  comes  in  this  direction,  it  passes 
directly  through  without  any  refraction;  but  an  oblique  ray  is 
turned  inwards,  so  as  to  form  a  focal  point  with  a  ray  coming  in 
a  similar  manner  from  the  other  side. 

These  being  the  principal  laws  by  which  vbion  is  governed, 
we  are  enabled  to  understand  the  distinct  offices  of  the  various 
parts  of  the  eye. 

The  transparent  cornea,  the  window  of  the  eye,  serves  to  collect 
the  rays,  and,  by  its  convexity,  to  refract  them  towards  the 
ocular  axis. 

The  agueoiu  humour,  besides  its  office  of  preserving  the  con- 
vexity of  the  cornea  and  allowing  the  iris  to  float  loosely  amidst 
it,  serves  likewise  to  refract  the  rays,  from  its  being  a  denser 
medium  than  the  atmosphere. 

The  crystalline  lent,  however,  is  the  principal  refracting  glass ; 
receiving  the  rays  in  some  measure  refracted  by  the  cornea  and 
aqueous  humour,  it  brings  them  to  a  focus  on  the  retina. 

When  either  the  cornea  or  the  crystalline  lens  is  too  convex, 
the  object  is  brought  to  a  focus  too  soon,  and  vision  is  indistinct, 
and  tlie  person  near-sighted.  This  is,  probably,  a  frequent 
defect  in  the  eyes  of  horses  that  shy,  in  which  we  often  find 
full  goggle  eyes.  When,  however,  the  cornea  or  the  lens  is  too 
flat,  a  contrary  defect  is  produced,  and  the  object  is  not  converged 
aoon  enough.     This  is  a  frequent  complaint  in  old  people,  who

[The  rye  of  the  horae  is  exceedingly  liable  todiscvM — qniteu 
much,  if  not  more  so,  than  the  human  eve ;  bul,  unlike  it,  thne 
diat^aaes  are  by  ii»  means  subject  to  sueJi  great  variety,  but  may 
lie  eomprehendcd  by  a  few  divisions.  We  have,  ihrn.  ninipM: 
ophtlialmia,  s]>ccific  ophthalmia,  cataract,  and  aiiuiuroaii 
paralysis  of  the  optic  nerve. 


SimjiU  Opktkatmui. 

This  disease  arises  from  some  external  injury,  sacb  as  a 
from  a  stick  or  whip,  a  bile  from  another  horse,  or  the  intrusion 
of  some  foreign  btuly.  It  n  im|>ortant  to  distinguish  this  dis- 
ease from  that  we  have  presently  to  iiotieci  winch  may  be  done 
wiiltout  much  difficulty,  by  an  attention  to  the  fulioning  symp- 
toms. Unless  the  injury  is  very  trifling,  there  is  usually  mucli 
sivelling  and  inflammation  of  tne  eyelids  aitd  its  cnvelopmeutf- 
Shortly  afterwards  we  find  an  opacify  of  tlie  transparent  comen; 
this  opacity  rarely  spreads  over  il>e  whole  of  the  rye.  but  it 
much  greater  at  one  pari  than  another.  On  inspecting  die 
eye  in  a  lateral  position,  «c  find  that  tlie  aqueous  Jiumour  it 
either  not  aifeGtodr  or  only  partially  so ;  and  on  looking  into  ik 
interior  of  tbc  eye,  wc  find  the  parts  presenting  a  hcttltliy  ap- 
pearance. 

TVeatmnt.  —  It  is  very  important  to  be  prompt  and  energetio 
in  our  treatment;  for  otherwise  there  is  great  dai^r  of  (he 
opacity  increasing  and  involving  the  whole  of  the  cornea,  so  at

to  occasion  blindness,  or  otherwise  to  be  permanently  fixed  in 
one  part,  so  as  to  obstruct  vision  and  defy  all  our  attempts  for  its 
removal.  When  the  inflammation  is  considerable  we  should 
lance  the  inflamed  vessels  of  the  eyelid,  and  encourage  the  bleed- 
ing as  much  as  possible,  and  at  the  same  time  open  the  angular 
vein  which  passes  from  the  eye  down  the  face.  In  performing 
this  operation  it  is  necessary  to  cut  in  some  measure  across  the 
Tein,  in  order  to  ensnre  its  bleeding  freely.  Ifthe  blood  should 
not  flow  freely;  it  will  be  better  to  bleed  from  the  neck  at  the 
same  time.  The  eye  should  be  frequently  fomented  with  warm 
water  the  first  day,  and  afterwards  the  following  lotion  should  be 
applied  round  and  in  the  eye  six  or  eight  times  a  day :  — 

Cold  water 1  pint. 

Tincture  of  opium 1  ounce. 

A  dose  of  physic  should  be  given;  and  if,  in  a  day  or  two, 
there  be  still  much  inflammation,  a  few  quarts  of  blood  may  be 
taken  from  the  neck  of  the  affected  side.  When  the  inflamma- 
tion has  in  great  measure  abated,  but  a  film  or  opacl^  remains 
on  the  cornea,  a  few  drops  of  the  following  stimulant  should 
be  applied  twice  a  day  with  a  camel's  hair  brush :  — 

Distilled  water 1  ounce. 

Nitrate  of  silver 1  or  S  grains. 

Or  instead  of  this,  a  litUe  vinum  opii,  or  tincture  of  opium  diluted 
with  an  equal  quantity  of  water. — £d.] 


Specific  Ophthalmia,  or  Iiifiammaiioa  of  the  Eye. 

[This  disease  used  to  be  called  by  farriers  moon  blindness, 
under  the  idea  that  its  periodical  attacks  were  influenced  by  the 
moon,  as  it  sometimes  occurs  about  once  a  month.  This  idea, 
however,  is  altogether  absurd,  and  its  periodical  returns  are 
rarely  so  frequent  as  once  a  month.  The  disease  consists  of  a 
specmc  inflammation  of  the  various  parts  of  the  eye  occurring 
without  any  immediate  external  cause;  and  though  in  great 
measure  curable  for  the  time,  yet  occurring  again  and  again, 
nntil  tlie  structure  of  the  eye  is  so  changed  by  these  re- 
peated attacks,  that  blindness  follows,  or  otherwise  a  cataract 
takes  place,  either  total  or  partial. 

The  lymptomt  generally  appear  somewhat  suddenly ;  in  the 
evening,  perhaps,  there  might  have  been  nothing  amiss,  but  on 
the  folrowing  morning  sometimes  both  eyes,  but  usually  one  eye 
only  is  found  nearly  closed  and  sufl'used  with  tears ;  there  is 
great  impatience  of  light,  and  indeed  it  is  somewhat  difficult  to 
induce  the  animal  to  open  the  lids  su£Bcienily  for  examination, 
and  when  he  does  so,  the  pupil  la  found  exceedingly  small,  so

horse  itsualty  report  that  some  hay  seeds  must  liavcf^oi  into  tlie 
eye,  or  titat  he  must  have  injured  it  in  some  way ;  but  a  proper 
examination  nill  detect  tW  diHi-reiicc,  and  tins  will  be  greatly 
assisted  if  wv  can  ascertain  tliat  tltc  horsv  luid  had  a  previous 
attack. 

The  progrcM  ol'  the  case  will  depctid  on  the  treatment  em- 
ployed, tliv  d(-|;;rec  of  inflammation,  and  the  particular  paru 
mu»t  iiHvclcd. 

I  have  known  a  <nim>  terminate  in  bltnditras  from  cataract  in

aubjeci  to  |>eriodical  attacks  tor  eight  years  witlioul  entirely 
losinfC  vision  at  last.  Sometimes  the  crystalline  lens  is  prii>- 
cijwlly  allected  ;  in  other  cases  the  iris  bi?ars  tl»c  brunt  of  ihe 
attack ;  in  some  instances  the  aqueous  humour  and  the  contca 
are  pvtncijuLlly  aflTcclcd,  and  in  others  the  viireoiu  humour  and 
the  relitui  art  chiefly  iliwnneil.  When  the  crystalline  lens  it 
principally  al!'ecie<l,  it  usually  become*  ogiatiue,  or  wlwit  is  calUtI 
ft  cataract  fornu,  wliicli,  however,  may  not  be  to  total  lu  entirHy 
to  destroy  vision.  When  tlie  iris  a  chidly  intlanted,  ilie  cast-, 
1  imagine,  does  not  terminate  so  quickly  in  blindness,  but  (lie 
attai^ks  are  of\en  frequent  and  very  troublesoine,  and  atteixted 
by  much  general  irritability. 

When  the  vitreous  humour  is  greatly  atfecti'd,  the  interior  of 
the  eye  often  becomes  of  a  yellow  muddy  colour,  and  the  eye 
•ometiines  shrinks  from  absorption  of  its  substance. 

Cnuses.  —  Tlie  causes  of  this  severe  disease,  which  so  often 
brings  the  price  ofa  horse  from  a  hundre<l  guineas  down  to  fiflcvni 
has  engaged  much  attcnilun,  and  been  the  subject  of  some  dis- 
pute. In  the  giviiU'i'  nuiuU-r  of  lioi^ses  tltat  are  thus  attacked, 
iIktc  i^  beyond  all  qtii-slion,  a  natural  prcdisjMiiilion  to  the

The  offspring  of  pai-ents  with  diseased  eyes  become  blind  tar 
more  frequently  than  the  produce  of  animals  with  healthy  eyes; 
and  to  the  circumstance  of  the  little  care  taken  in  titc  choice  of 
the  (lam  or  the  sire  may  to  a  ^reat  extent  be  attributed  the  fre- 
quency of  the  <litease.  We  find  that  sheep  and  oxen,  compared 
with  tlie  horse,  am  ranly  attacked  with  diseased  i-yca,  and  fea

domesticated,  is  taken  into  a  warm  stable,  exposed  to  the  fumes 
from  the  dung  and  urine,  fed  on  stimulating  food,  and  ot^n 
osed  with  great  severity,  either  in  the  saddle  or  harness.  Here 
we  hare  several  causes :  a  plethoric  state  of  the  system  is  induced 
by  stimulating  food,  by  which  much  blood  is  sent  to  the  head; 
this  disposition  of  the  blood  is  still  further  increased  by  exertion, 
particularly  in  harness,  from  the  pressure  of  the  collar,  retarding, 
in  some  measure,  the  return  of  the  blood.  The  eyes  are  exposed 
to  the  stimulus  of  ammoniacal  gases,  the  irritating  efiect  of  which 
on  our  own  eyes  may  be  readily  experienced ;  besides  which  the 
young  animal  is  often  kept  in  a  dark  stable,  whence  he  is  often 
suddenly  brought  into  the  fiiil  glare  of  the  noon-day  sun.  Can 
we  wonder  that  this  combination  of  causes  should  produce 
disease,  or  that  the  delicate  structure  of  the  organ  of  vision 
should  be  the  first  to  suffer?  We  have  here  both  exciting 
and  predisposing  causes.  A  weakness  of  the  structure  of  the 
eye  is  often  derived  from  the  parents,  and  the  causes  above- 
mentioned  soon  bring  on  disease. 

Specific  ophthalmia  usually  makes  its  appearance  between 
the  fourth  and  seventh  year,  but  sometimes  before,  and  occasion- 
ally in  old  horses. 

Harness  horses  are  certainly  more  liable  to  the  disease  than 
those  used  for  the  saddle  alone ;  and  horses  with  a  small  sunken 
eye  are  more  likely  to  be  affected  than  those  with  full  open  eyes. 
The  disease  is  also  more  likely  to  occur  amongst  coach  and  post 
horses,  where  a  number  are  kept  together,  than  amongst  gentle- 
men's studs. 

Treatmtni.  —  Although  different  parts  of  the  eye  may  be 
affected,  yet  the  attack  being  one  of  inflammation,  the  treat- 
ment should  be  pretty  much  the  same  in  all  cases,  and  should 
consist,  in  the  first  place,  of  local  and  general  bleeding  and 
physic,  as  advised  for  simple  ophthalmia ;  the  bleeding  should 
be  repeated  as  required ;  warm  fomentations  should  be  used  at 
firet,  and  should  be  succeeded  by  the  cold  lotion  before  advised, 
or  the  following,  which  is  more  stimulating :  — 

Sulphate  of  zinc 1  drachm. 

Superacetate  of  lead  ...  4  scruples. 
Water 1  pint. 

Mix,  and,  after  shaking  them  together,  filter  through  blotting 
paper. 

When  the  inflammation  has  in  some  measure  subsided,  a  seton 
may  be  inserted  under  the  eye,  and  kept  in  for  several  weeks. 

Some  persons  object  to  the  seton,  on  account  of  the  mark  it 
leaves  for  some  time,  and  recommend  instead  one  to  be  placed 
ander  the  jaws. 

A  few  drops  of  wine  of  opium  may  be  daily  insinuated  into

DISEASES    OF   THE    EYE. 

Total  cataract  ia  an  entire  opacity  of  the  crystalline  lens,  so 
that  it  no  longer  admits  rays  of  light  to  pass  through,  and  blind- 
ness is,  of  course,  the  result.  It  proceeds  from  inSammation  of 
the  lens,  and  it  usually  takes  many  attacks  to  produce  total 
opacity.  It  may  be  readily  detected  by  exposing  the  horse  to  a 
moderate  light,  such  as  that  at  the  stable  door,  and  carefully 
looking  into  the  interior  of  the  eye. 

Sometimes  the  opacity  is  quite  white,  at  other  times  grey,  and 
occasionally  yellow.  The  lens  undergoes  some  alterations  of 
form  when  a&cted  with  cataract,  becoming  much  more  globular 
than  before. 

In  the  human  subject,  it  is  well  known  that  the  operation  of 
couching  is  practised,  which  consists  either  in  extracting  the 
lens,  or  thrusting  it  back  into  the  vitreous  humour,  where  it 
becomes  absorbed.  In  the  horse,  however,  this  operation  is 
almost  impracticable,  and  is  otherwise  objectionable,  inasmuch 
as  partial  vision  would  alone  be  restored,  which  would  probably 
make  the  animal  shy,  as  it  is  impossible  to  adapt  spectacles  to 
bim  to  supply  the  want  of  the  lens,  as  is  done  in  the  human 
suUecL 

It  often  happens  that  when  a  cataract  has  completely  formed 
in  one  eye,  the  other,  although  it  had  been  before  attacked, 
becomes  strengthened  and  remains  sound.  This,  indeed,  is 
the  most  favourable  termination  of  specific  ophthalmia  that  can 
possibly  occur. 

Partial  caiaraet  is  when  there  are  opaque  spots  in  the  lens, 
but  not  sufficient  to  shut  out  vision  entirely.  It  is  generally  the 
consequence  of  active  infiammation,  which  may  recur  again  and 
again  until  the  transparency  of  the  lens  is  entirely  gone.  In 
other  cases,  the  inflammatory  attack  may  not  again  recur,  but 
partial  vision  remain  through  life.  In  examining  a  horse,  we 
may  expect  a  recurrence  of  the  inflammation  if  the  other  parts 
of  the  eye  are  disorganised :  but  if  the  opacity  is  entirely  con- 
fined to  the  lens,  and  the  other  parts  appear  perfectly  clear, 
and  the  iris  is  not  particularly  irritable  wlien  exposed  to  the 
light,  we  may  consider  it  probable  that  the  horse  will  preserve 
what  sight  he  possesses,  although,  of  course,  he  cannot  be  con- 
sidered as  sound. 

Sometimes  we  find  slight  specks  on  the  crystalline  lens 
occurring  without  any  previous  inflammation,  or  at  least  any 
that  obtained  notice.  The  appearance  of  these  specks  may,  by 
attention,  be  distinguished  from  partial  cataract.  Instead  of 
being  white,  yellow,  or  green,  they  are  of  a  grey  hue,  and  their 
opacity  is  not  so  great  as  in  cataract.  It  is  extremely  probable 
that  the  opaci^  is  confined  to  the  capsule  or  covering  of  the 
lens;  and,  in  several  instances,  I  have  known  them  disappear 
without  any  remedy  having  been  applied.     Other  veterinary

CHAP.  XLVHI. 

ON    LAMENESS    FROM    STRAINS. 


Lameness  is  produced  by  a  variety  of  causes,  so  numerous, 
and  often  so  obscure,  that  to  discover  its  seat  with  accuracy 
and  promptitude  is  a  mark  of  professional  acumen  to  which 
every  young  practitioner  should  aspire.  Let  him  not,  how- 
ever, be  \ea  by  this  consideration  to  give  a  hasty  opinion  in 
cases  of  lameness ;  but,  on  the  contrary,  let  him  investigate  care- 
fully, and  reflect  deliberately,  upon  all  the  circumstances  of  the 
case,  and  be  well  assured  that  he  knows  the  seat  and  nature  of 
the  lameness  before  he  gives  an  opinion.  Lameness  may  exist 
in  a  great  variety  of  degrees;  the  shades,  for  so  they  may  be 
iiame<£  between  soundness  and  positive  lameness  are  so  nume- 
rous, that  to  give  a  name  to  each  would  be  impossible ;  and  if 
possible,  unprofitable.  The  immediate  cause  of  lameness,  in 
the  majority  of  cases,  is  the  effort  of  the  animal  to  relieve  the 
lame  leg  by  throwing  his  weight  on  the  sound  one,  thus  causing 
that  unequal  action  called  lameness.  The  serious  loss  and  in- 
convenience arising  from  lamenera  have  excited  particular  atten- 
tion to  the  subject ;  and,  though  considerable  improvement  has 
been  made  within  a  few  years  in  the  art  of  shoeing,  as  well  as  in 
the  treatment  of  lameness,  it  is  a  generally  acknowledged  fiict, 
J  believe,  that  a  large  proportion  of  the  lameness  that  occur  will 
only  admit  of  palliation,  and  that  a  considerable  number  are 
absolutely  incurable,  especially  those  in  the  feet 

In  alluding  to  the  improvements  in  shoeing,  I  do  not  mean 
to  include  that  which  has  been  introduced  from  France)  except 
as  it  regards  the  nailing  of  those  shoes;  for  as  to  the  French 
shoe,  and  its  boasted  ajugture,  I  think  it  the  most  absurd  imagin- 
able. That  lameness  is  much  more  frequent  in  this  country 
than  in  France  is  a  fact  that  must  be  admitted,  and  ought  to  be 
deeply  lamented,  because  it  is  an  evil  that  may  and  ought  to  be 
prevented.  On  what,  then,  it  may  be  asked,  does  this  par- 
ticular frequency  of  lameness  in  this  country  depend  ?  The 
French  say  on  shoeing ;  but  It  is  not  really  so :  on  the  contrary, 
I  am  of  opinion  tliat  tne  English  shoeing,  speaking  generally,  is 
the  best  in  the  world.  The  frequency  of  lameness,  so  loudly 
and  justly  complained  of,  arises  wholly  from  the  immoderate

\_StraiHt  may  occur  in  muscles,  in  ligaments,  and  temlons,  and 
in  (lie  incmbraiies  l)v  which  tenclona  are  joined  togollicr,  and 
they  prove  a  very  frequent  source  of  Unu-ncM  in  the  horM*.  They 
consist  in  an  overstretching  of  the  injured  parts,  whereby  is- 
flammntion  is  prmluci-<l,  and  it  becomt>s  hot,  tender,  and  fre- 
qiii-ntly  swollen ;  »oim-timw  some  of  the  smaJI  b1ood-r««Kl*  are 
r(iptur<tl,  and  blood  is  exiruTOMiled  ;  itt  others  a  liquid  is  effused 
by  the  vessels,  and  thus  causn  the  swrelliiig.  The  lameness  U 
produced  not  so  much  by  the  pain  tlie  animal  receives  when  the 
injured  part  comes  to  the  ground,  but  rather  by  the  effort  to 
prevent  this  pain  as  much  as  possible  by  Ireading  li|jhtty  on  the 
injuiTd  limb,  and  with  grcnicr  force  on  the  other. 

Strains  of  tlte  muscles  are  generally  more  painful  than  iliose 
of  ti*n<lon*  and  ligaments,  front  the  greater  organisation  of  tlie 
part ;  but,  for  the  same  reason,  tlioy  are  generally  more  eflec- 
tually  cured,  and  in  a  shorter  space  of  time.  In  strains  of  the 
ligaments  and  tendons  what  we  have  principally  to  fear  is  the 
pernMnenl  enlargement  of  the  part,  by  the  deposition  of  new 
substance  around  it;  this  Ix'ing  one  of  nature's  methods  in  re- 
lieving intliinimutimi,  but  which  is  getK-rally  the  source  of  great 
wenknets  of  the  [inrL 

In  tlie  Irtatmatt  of  strains  our  principal  object  must  lie  to 
relieve  the  inflammation  as  quickly  as  po^ibie,  and  thus  to  )>re- 
vent  an  enlargement  from  uking  place;  witlj  this  view  we 
should  have  recourse  to  bleeding,  locally  or  generally,  warm 
fomentations,  poultices,  and  coItT  lotions,  avoiding  stimutanU 
till  tlie  Inflammation  ia  considerably  abated.  —  Ea.] 

ShoMer  Strain. 

[Some  years  since  the  practice  of  tlte  veterinary  art  was 
fined  to  farriers,  wtioie  want  of  knowledge  of  inorbkl  anatomy 
left  them  to  guess  at  the  ^at  of  lanioness  in  numerous  insiancea; 
uikI  thus  in  lite  greater  number  of  lamenesses  in  the  fore  ex- 
tri-mity,  where  no  external  signs  were  mnni tested,  the  shoulder 
was  invariably  considered  the  seat  of  disease.  Many  veterinary 
«urgM>ns  flnding  thiji  to  be  errotu-ous,  in  numerous  instances 
Itave  flown  to  tlie  opposite  extreme,  and  declared  tltat  hoisn 
were  never  lame  in  the  shoulder. 

Shoulder  lamenesses  are  certainly  rare,  but  they  OCCaoionaUy 
occtir,  and  may  nenri)'  iilwiiys  be  delected.  There  are  several 
(Nirta  of  tlte  lihouUler  liable  to  injury;  Kometinn-s  the  muscles

or  fipremling  apart.     Occasionally  the  large  triceps  muscle,  |^ws»-

ing  from  the  back  port  oftlie  scapula  to  the  elbow,  ie  tlie  seat  of 
injury. — Ed.]  More  frequently  than  this  the  lameness  depends 
on  a  strain  of  the  tendon,  (or  an  injury  of  the  synovial  cavity,  or 
bursa  mucosa,  through  which  the  tendon  passes,)  which  arises 
from  a  protaberance  on  ttie  lower  part  of  the  shoulder  blade, 
and  slides  over  the  large  grooved  process  at  the  head  of  the 
shoulder  bone.  This  large  grooved  process  is  covered  with  a 
slippery  cartilage,  as  in  other  syiiovi^  cavities,  to  prevent  any 
friction  while  the  limb  is  in  motion.  I  have  seen  shoulder 
lameness  that  appeared  to  depend  upon  a  rheumatic  affection  of 
this  part.  The  manner  of  the  horse's  going,  when  this  part  is 
the  seat  of  lameness,  is  very  remarkable.  In  endeavouring  to 
trot,  and  sometimes  even  in  walking,  the  fore  leg  suddenly  gives 
way  or  bends,  and  it  is  only  by  a  considerable  effort  that  the 
horse  can  save  himself  from  filing.  I  had  a  filly  under  my 
care  for  this  lameness  which  fell  down  several  times  in  walking, 
Tlie  remedies  I  employed  were  passing  a  seton  over  the  point  of 
the  shoulder,  and  blistering  all  around  it  pretty  freely.  This, 
and  confining  her  some  weeks  in  a  box,  effected  a  cure. 

[I  lately  met  with  a  case  of  this  description  which  arose  from 
severe  struggling  after  being  thrown  for  an  operation.  The 
use  of  the  limb  was  nearly  lost  for  several  days,  and  the  seat  of 
injui^was  evidently  in  the  triceps  muscle,  just  above  the  elbow, 
which  became  much  enlarged.  Fomentations,  bleeding,  and 
stimulants  effected  a  recovery. 

The  n/mptoms  of  shoulder  lameness  are  generally  detected 
without  much  difficulty.  The  horse  is  generally  lame  in  the 
walk  as  well  as  the  trot,  which  is  not  the  case  with  other  lame- 
nesses of  equal  severity.  The  lameness  is  particularly  notice- 
able on  going  down  hill.  Unlike  other  lamenesses  the  injured 
leg  is  not  extended  so  far  as  the  other,  and  is  often  carried 
forwards  in  a  circular  direction  ;  there  appears,  indeed,  greater 
pain  evinced  in  extending  the  limb  than  in  resting  the  weight 
of  the  body  upon  it.  On  moving  the  limb  forwards,  backwards, 
and  laterally  there  is  often  considerable  pain  evinced  by  the 
animal ;  this,  however,  depends  on  the  severity  of  the  case. 

Horses  with  thick,  upright,  and  badly  formed  shoulders  are 
more  liable  to  these  itijurles  than  others,  from  the  inability  of 
the  parts  to  respond  adequately  to  exertions  demanded,  whence 
they  become  over  exerted  and  strained.  The  injuries  are  there- 
fore produced  in  galloping  over  heavy  grounds  or  ruts,  or  going 
bat  down  hill  in  harness,  or  from  some  accidental  false  step. 

The  treatment  should  consist  of  bleeding  largely  from  the 
plate  vein  as  it  is  commonly  termed,  just  opposite  the  elbow- 
joint  ;  three  to  five  quarts  may  be  alntracted  with  advantage. 
Should  there  be  considerable  pain,  and  particularly  if  the  parts 
feel  hot  and  tender,  the  shoulder  should  be  fomented  frequently

Will  liere  be  useful,  before  tJte  injuries  of  thoeo  part«  are  coii- 
tidercd. 

'llie  JUzar  tetidani,  or  back  sinews,  are  the  appendages  or 
ropea  to  the  flexor  muscles,  which  are  situated  chiefly  on  the 
hack  part  of  the  forc-ann  of  ilie  hoi^se ;  when  these  muscles  are 
full  or  pminiiient,  lupering  downwards  in  a  sinewy  form,  it  indi- 
cates great  strength  of  the  fore-leg,  and  the  sinews  will  always 


OH    LAMENESS    FROM  STHAINS.  269 

be  found  of  correepooiliiig  strength.  The  elbow  id  such  a  fore- 
leg is  generally  standing  out  from  the  side,  and  not  turned  in 
and  concealed,  as  it  is  in  fore-arms  of  a  different  description,  in 
the  side  of  the  chest  or  sternum.  These  sinews  are  two  in 
number,  and  the  one  is  inclosed  in  the  other,  so  that  the  latter 
forms  what  is  termed  a  sheath  for  it.  The  inner  tendon,  or,  as 
it  is  named,  the  perforatu,  is  one  of  great  strength,  nearly  round, 
and  extends  down  to  the  bottom  of  the  foot,  or  coffin  bone, 
into  which  it  is  firmly  implanted.  The  other,  or  sheath,  named 
pefforabu,  is  considerably  thinner,  forming,  indeed,  a  mere 
sheet  of  tendon,  especially  at  those  parts  where  windgalls  happen ; 
these  were  formerly  supposed  to  be  enlarged  bursffi  mucoace, 
but  I  have  clearly  demonstrated  that  they  are  nothing  more 
than  the  tendinous  sheath,  distended  with  synovia. 

These,  then,  are  the  two  tendons,  which,  taken  together,  form 
the  back  sinews.  Between  these  two  tendons  there  are,  in  two 
parts,  thin  membranes,  by  which  they  are  joined  together;  these 
membranes  appear  to  serve  as  bridles,  allowing  the  perforans  ten- 
don tomovealittle  waywilhin  the  perforatus,  and  then  preventing 
any  further  motion.  The  situation  of  those  membranes  is  about 
midway  in  the  leg,  and  midway  in  the  pastern.  If  ihe  coffin 
joint  happen  to  be  extended  in  a  way  the  animal  ^as  not  pre- 
pared for,  both  these  membranes  are  ruptured.  The  conse- 
quence is,  an  effusion  of  blood  between  the  two  tendons. 

It  will  be  seen  from  the  Plate  that  there  is  a  strong  ligament, 
but  in  appearance  like  a  tendon,  coming  from  the  back  part  of  the 
knee,  passing  down  about  four  or  five  inches,  and  then  incor- 
porating with  the  perforans  tendon.  This  I  have  named  the 
great  ligament  of  the  back  sinew,  and  its  office  is  of  a  very  im- 

Krtant  nature,  being  no  less  than  that  of  supporting  the  whole 
dy ;  that  is,  supposing  the  flexor  muscles  to  be  fatigued,  and 
incapable  of  doing  it,  and  in  consequence  giving  way;  for  in 
that  case  this  great  ligament  forming  one  rope  with  the  great 
back  sinew,  and  this  sinew  being  firmly  insertra  into  the  bottom 
of  the  coffin  bone,  it  must  of  necessity  be  the  sole  support  of  the 
whole  weight.  This  ligament  may  also  be  ruptured  in  strains. 
I  have  seen  a  case  of  this  kind,  and  such  must  have  been  the 
cases  that  have  been  described  as  a  rupture  of  the  back  sinew, 
an  accident,  as  must  be  obvious  from  the  plate  *,  that  cannot 
happen. 

One  part  only  remains  to  be  described,  and  that  is  the 
suspensory  ligament.  This  ligament  passes  down  from  behind 
the  knee  close  to  the  shank  bone,  until  it  arrives  to  within 
three  inches  and  a  half  of  the  superior  and  posterior  part  of  the

OH    LAMEKESB    FROM    8TBAINS.  271 

Strain  of  the  Flexor  Tendons,  or  Back  Sinews. 

[This  injury  is  of  frequent  occurrence,  and  being  often  neg- 
lected in  its  early  stages,  an  enlargement  of  the  tendons  takes 
place,  which  greatly  depreciates  the  value  of  the  animal.  This 
being  the  case,  the  injury  whether  trivial  or  severe,  should  never 
be  thought  lightly  of,  but  always  submitted  to  treatment. 

The  Sympbmu  are  in  a  severe  case,  lameness  and  heat,  and 
swelling  of  the  affected  part ;  on  pressing  the  sinews  consider- 
able pain  is  evinced.  Sometimes  the  fetlock  almost  touches 
the  ground  from  relaxation  of  the  sinews  or  their  connections. 
Tbe  enlargement  in  some  cases  is  so  considerable,  that  the 
unews  cannot  be  discerned ;  this  oflen  arises  ironi  eBusion  of 
blood  in  the  sheath,  but  the  tendons,  themselves,  are  likewise 
ioBamed. 

The  treatment  in  a  severe  case  should  consist  of  copious 
bleeding  from  the  arm,  which  may  be  repeated  the  second  op 
third  day  if  necessary ;  a  pattai  shoe  should  be  placed  on  the  foot 
of  the  affected  1^,  so  as  to  put  the  sinews  ui  a  state  of  rest ;  and 
tbe  limb  should  oe  placed  in  a  bucket  of  warm  water,  and  fre- 
quently fomented  for  a  long  time  together.  If  this  cannot  be 
conveniently  done,  a  linseea  meal  poultice  should  be  placed  on 
the  1^  and  wetted  several  times  in  the  day  with  warm  water. 
On  the  second  or  fourth  day  the  following  lotion  may  be  sub- 
stituted for  tbe  fomentation,  a  linen  bandage  being  applied, 
and  freqaenlly  saturated  with  the  lotion :  — > 

Muriate  of  ammonia.. 1  ounce. 

Fyroligneous  acid........ S  ounces. 

Spirits  of  wine 2  ounces. 

Camphorated  spirit. 2  drachms. 

Cold  water 1^  pint  — 

Mix. 
When  the  part  is  totally  free  from  inflammation,  if  a  swelling 
remains,  it  should  be  either  blistered  or  fired,  the  latter  is  the 
most  effectual,  and  should  be  preferred  if  the  blemish  is  not 
objected  to.  —  En.j 

Strmmofthe  Fetlock  Joint. 

This  injury  may  be  confined  to  the  joint  itself  when  there  is 
lameness  and  heat  but  not  much  swelling,  but  its  seat  generally 
it  the  ligaments  surrounding  the  joint. 

The  Symptoms  are  similar  to  those  be&ire  mentioned  in  strains 
of  the  sinews,  and  the  treatment  also  should  be  very  similar.  A 
patten  shoe,  however,  is  not  so  imperatively  called  for,  and  if 
used  should  not  be  continued  so  long.

tlic  upper  and  [>o«ierior  [tart  of  the  great  metacarpal  or  cannon 

bonr.     About  three  or  four  inches  down  it  joins  tlvc  prtforani 

tendon,  and  becomes  intimately  mixed  witb  it.     If  Una  part  Ja 

examined  it  will  cicarlv  appear  lluit  a  rupture  of  tlio  auspcaaoTy 

ligament  of  the  lotlocit  jomt  would  not  bring  the  hor»e  down 

upon  his  foiloek  joint  unlc«s  this  sutpcniory  ligament  of  the 

pcrforanit  tL*ndon  were  to  give  way  alao.     I  have  met  with  two 

cacei  of  a  rupture  of  th«  ligamenta,  bj  which  the  two  pastern 

bone*  are  held  logeilior.     It  happened  to  two  nerved  norsfs, 

tliat  were  driven  in  the  subscription  coach  from  Bath  to  Exeter, 

Botli  these  horses  came  down  upon  the  fedock  joint,  and  were 

tlierclbrc  shot.     A  perpendicular  section  was  made  of  the  foot 

and  pastern,  when  this  dislocation    of  the  pastern  bones  was 

shown   very  conspicuously.     The  suspensory   ligament  of  the 

paslern  joint  embraces  the  two  Bcesmoidj  laterally,  and  when 

ruptured  it  is  probable  that  only  one  of  its  branclivs  a  broken, 

which  is  followed  by  8  dislocation  of  one  or  both  avumoids: 

this  accident  also  I  have  n-cn. 

This  breaking  down  in  most  probably  owing  to  a  nipture 
or  Ktraiu  of  tlie  ligaments  pusHing  from  tlie  sesamoid  bones  to 
the  paaierns,  which,  on  being  divided,  greatly  increases  the  ob- 
liquity of  th«  joint.  In  lh«  treatment  of  such  cases  the  patten 
shoe  most  be  early  applied,  and  the  same  means  resorted  to  a« 
for  other  strains. 

The  Sutp«tU0iy  iJtiainenU  which  pass  down  the  leg  between 
tl)C  back  sinews  and  the  bone,  are  often  the  seat  of  inflammation, 
I  enlargement,  and  lameness.  The  nature  of  this  affection  is  U-M 
'  severe,  though  often  more  obstinate,  than  tluit  of  the  tendons.

but,  there  being  less  inflammation,  firing  or  blistering  should  be 
earlier  resorted  to.  —  Ed.] 

Are  soft  puffy  swellings  of  a  similar  nature  to  bog  spavins  and 
thoroush-pins.  They  are  found  both  in  the  fore  and  hind  legs 
at  the  fetlock  joint.  There  are  two  situations  in  which  they  may 
appear;  one  on  each  side,  and  at  an  equal  distance  from  the 
front  and  back  of  the  fetlock  joint ;  the  other  on  each  side  of  the 
flexor  tendons.  The  former  communicate  with  the  fetlock  joint 
itself;  the  latter,  which  are  larger  and  more  frequent  than  the 
others,  with  the  sheath  of  the  flexor  tendons.  Thus  connected, 
there  must  he  considerable  danger  in  opening  them.  Windgalla 
are,  therefore,  neither  more  nor  less  than  a  distension  of  the 
synovial  bags  with  synovia,  and  sometimes  an  extension  of  these 
bags  by  a  rupture  of  their  connections.  The  cavities  which  are 
the  seat  of  windgalls  are  shown  in  the  frontispiece  plate, —  one 
just  behind  the  lower  part  of  the  cannon,  the  other  behind  the 
tendons.  Sometimes  we  find  these  enlargements  at  the  front  of 
the  fetlock  joint,  or  rather  on  each  side  of  the  extensor  tendon. 
In  this  case  they  do  not  conmiunicate  with  the  joint,  but  are 
merely  the  distension  of  the  mucous  capsule  just  about  the  joint. 
They  are  also  found  above  the  knee,  and  in  various  other  parts 
of  the  body. 

Blistering  these  windgalls  will  generally  cause  their  disappear- 
ance for  a  time;  but  they  are  sure  to  return  wiih  work.  Punc- 
turing them  with  a  needle  in  various  places,  so  as  to  cause  an 
adhesion  of  the  side  of  their  internal  surfaces  has  been  suggested, 
and  is  well  worth  a  trial. —  Ed.] 


Strain  of  ike  Coffin  Joint. 

[[Under  this  term,  most  obscure  lamenesses  of  the  fore  ex- 
tremity used  to  be  classed  by  those  who  were  of  opinion  that  the 
shoulders  were  not  the  seat  of  injury.  Later  research,  however, 
has  discovered  that,  in  nine  cases  out  of  ten,  the  seat  of  these 
obscure  lamenesses  is  not  in  the  coffin,  but  in  the  navicular  joint 
somewhat  posterior  to  it.  The  cofBn  joint  is  so  firmly  secured 
within  the  hoo^  and  is  so  limited  in  its  movements,  that  its 
ligaments  are  rarely  striuned.  This,  however,  is  occasionally 
the  case,  and  may  be  detected  by  heat  round  the  coronet,  in  ad- 
dition to  the  lameness. 

The  treatment  must  consist  in  bleeding  from  the  foot  and 
poultices,  and  followed  by  blistering  the  coronet. — En.]

DISLOCATION   OF   THE    PATELLA.  275 

gaished  from  lameness  of  the  hock,  or  fetlock  joint,  by  the  sudden 
catching  up  of  the  hind  leg  in  the  two  latter. 

Strain  or  Irgtiry  of  the  StiJU. 

Lameness  in  the  stifle  is  known  by  the  difficulty  the  horse 
feels  in  putting  forward  the  hind  leg;  also  by  swelling  and  ten- 
derness of  the  parL  It  is  generally  produced  by  external  vio- 
lence, though  it  may  be  caused  by  a  strain. 

The  treatment  should  consist  of  bleeding,  either  generally  or 
from  the  thigh;  warm  fomentations  to  the  part,  followed  by 
cold  lotions ;  and  if  the  lameness  continues  the  joint  should  be 
btbtered,  orsetons  inserted  over  it. 

Dislocation  ofthePateUa. 

lliere  is  another  kind  of  lameness  in  the  stifle,  which  is  some- 
times only  of  a  temporary  nature,  and  has  more  the  appearance 
of  spasm  or  cramp  of  the  muscles ;  but  is,  in  fact,  a  dislocation  of 
the  patella.  It  takes  place  wlien  a  horse  is  suddenly  moved  in 
the  stall,  or  when  first  taken  out,  or  when  first  moved  after 
having  been  ridden  and  then  standing  still  a  short  time.  Ilie 
attack  sometimes  lasU  only  a  minute  or  two,  but  is  often  re- 
curring. It  occurs  chiefly  in  colta,  or  young  horses.  When  a 
horse  is  attacked  with  this  cramp,  as  it  appears  to  be,  he  con- 
tinues with  the  hind  leg  stretched  out,  stiff,  and  apparently  in 
great  pain ;  he  then  suddenly  draws  it  up  with  a  jerk,  and  the 
knee  pan,  or  patella,  can  sometimes  be  heard  to  go  into  its  place 
again. 

[The  injury  here  spoken  of,  and  so  frequently  mistaken  for 
cramp,  is  neither  more  nor  less  than  a  dislocation  of  the  patella 
or  knee  pan,  whereby  the  motion  of  the  joint  is  altogether  pre- 
vented, and  the  leg  becomes  stiff  and  immoveable.  Sometimes, 
from  the  frequent  recurrence  of  this  affection,  and  its  often  spon- 
taneous cure,  the  articulating  surface  of  the  patella  becomes 
flattened,  and  the  animal  is  rendered  almost  useless,  being  con* 
tinudly  subject  to  the  dislocation. 

In  other  cases,  the  bane  cannot  be  restored  to  its  proper  situ- 
ation without  assistance,  which  should  be  thus  rendered.  The 
operator  should  place  himself  behind  the  animal,  and  putting 
one  arm  between  the  thighs,  clasp  his  hands  in  front  of  the  stifle. 
The  leg  now  being  drawn  forwards  by  an  assistant,  the  patella 
should,  at  the  same  time,  be  forced  in  by  the  operator. 

A  blister  or  charge  should  be  placed  over  the  part  to  prevent 
or  retard  its  motion,  and  the  animal  kept  in  a  state  of  rest  for 
some  days.  In  cases  of  frequent  recurrence,  the  part  may  be 
fired,  with  a  view  of  bracing  the  skin.  —  Ed.}

hammer  and  chisel,  but  (lie  production  of  n  Im^e  blemish  from 
the  desiruclion  of  skin  was  the  consequence  of  ibis  barbarotix

former,  was  the  application  of  corrosive  subliiikate,  or  other 
strong  caustic,  so  as  to  occasion  a  sloug));  in  this  case,  too,  the 
pcmedy  was  as  bad  as  the  disease, —  the  horse  was  disfigured  for 
life.  Belier  and  more  recent  treatment  tlian  this  was  either 
firing  or  blistering.  The  objection  to  the  former,  however,  was 
tite  marks  it  produced;  and  to  the  latter,  in  common  with  the 
former,  tiiat  though  (ho  lameness  was  removcti,  it  very  frctjucntly

and  by  drawing  it  backwards  and  forwards  on  the  splint,  pressing

when  the  lamcnesa  is  slight,  and  the  lu>rse  cannot  be  spared 
from  work  more  than  a  few  days,  it  is  well  to  apply  a  mild

"  Ringbone  is  n  deposition  of  ossific  matter  on  the  pastfTll 
bones,  which,  from  frequently  exiendin;;  round  tbem,  derives  itt 
common  appellation.  It  exists  in  various  ilcgre^  eomeiimn 
being  very  slight,  nnd  in  odicrs  surrounding  the  bones,  niid 
ftltogcthcr  obscuring  ihi-ir  reni  form.  Kingbonrs  arUe  either

they  iixually  do,  e»me  on  ilowly.  Ic  often  )Kip()ens  tbiit  u  liorse 
is  Inine,  and  it  is  aoniewiial  difficult  to  discover  tlie  seat  of  liii 
lameness;  but,  after  a  while,  a  ringbone  commonly  fbrms. 
Horses  with  short  upright  joints  arc  disposed  to  this  disease 
from  the  concu^ion  to  which  ibey  are  liable,  and  more  par- 
ticularly if  their  action  is  high :  and  1  have  also  found  rhnt 
hoi-ses  vriih  particularly  small  It-et  are  likewise,  from  the  same 
reason,  more  exjwscd  to  these  ossifKaiions  than  others  witli 
larger  feet.  Tlie  bin<t  legs  arc  subject  to  ringbones  as  well  as 
tlie  fore,  but  not  so  fri'tiuently ;  an<l  when  they  apiwar  beliind,

and,  after  that,  evaporating  applications  to  the  part,  with  the 
jmraersion  of  the  limb  frequently  in  a  bucket  of  cold  water. 
When  perfectly  cool,  but  not  before,  we  may  resort  to  counier 
irritation.  If  the  horse  is  blistered,  the  operation  should  be 
repeated  two  or  three  times,  or  the  iodine  and  mercurial  oint- 
ment may  be  substituted.  If  firing  be  employed,  it  is  necessary 
to  6re  deepl}',  and  we  may  blister  a  few  weeks  afterwards. 
Turning  out  to  grass  is  desirable,  as  it  insures  a  long  rest  j  or, 
what  is  still  better,  after  the  horse  has  rested  for  one  month, 
sending  him  to  plough  for  several  more  on  soft  ground,  sup- 
posing, of  course,  that  he  is  adapted  for  such  labour. 

"  Professor  Sewell  recommends  the  operation  of  periosteotomy 
for  cases  of  ringbones  as  well  as  for  splints. 

"  Ossification  of  Ike  lateral  cartilagex  is  commonly  known  by 
the  term  *'  &lse  ringbones."  It  is  produced  by  concussion,  and, 
consequently,  heavy  horses,  with  high  action,  are  more  liable  to 
it  than  others,  and  more  particularly  if  they  are  employed  on  the 
London  pavement.  It  generally  comes  on  slowly,  and  originates 
in  different  parts  of  the  cartilage  in  different  horses;  sometimes 
commencing  at  the  anterior  part  of  the  cartilage,  bitt  more 
frequently  at  the  posterior  and  inferior  part.  A  great  portion 
of  the  heavy  dray  horses  in  London  have  ossified  cartilages;  and 
in  the  country  nothing  is  more  common  than  for  cart  horses 
with  ossified  cartilages  to  work  on  the  road,  and  particularly  at 
plough,  entirely  free  from  lameness.  The  lateral  cartilages, 
when  ossified,  are  considerably  larger  than  before:  they  con- 
sequently press  on  the  skin,  and  the' surrounding  parts,  and  in 
this  way  assist  in  producing  lameness  and  inconvenience. 

"  Treatment,  —  We  are  rarely  called  upon  to  treat  the  disease, 
unless  it  is  attended  with  lameness,  which  may  either  be  pro- 
duced by  inflammation  going  on  in  the  part,  or  from  the  greater 
jar  the  foot  receives  from  the  loss  of  an  important  spring.  If 
the  former  be  the  case,  our  object  most  be  to  remove  the  in- 
flammatory dispositioi],  and  to  stay  the  further  deposition  of 
bone.  Should  there  be  any  appearance  of  heat  externally,  we 
may  first  bleed  from  the  coronet,  and  afterwards  proceed  to 
counter-irritation,  blistering  the  part  several  times. 

"  If  the  ossification  is  fully  formed,  and  there  are  no  signs  of 
active  inflammation  going  on,  we  can  then  do  little  more  than 
endeavour  to  diminish  the  jar  of  the  foot.  It  is  the  practice  in 
these  cases  to  fire  the  coronet,  but  no  benefit  can  be  eflected 
by  the  operation;  it  is  both  empirical  and  unmeaning.  We 
shall)  however,  find  much  benefit  from  the  use  of  leather  soles, 
taking  care  that  the  part  applied  to  the  heels  is  tlie  thickest. 
In   conjunction  with   leather,   bar  shoes  resting  lightly  on   the

frofEK  will  alTord  still  greater  relief.  If  1e«llier  soles  are  no( 
UM-d,  *  piece  ol'  leather  correspond inj;;  to  the  shoe  may  be  riveted 
to  biilh  lieels,  which  plan  will  coimiderably  obviate  cuncua&ion. 
By  thfs*'  nieaaiircs  in  the  country  we  caii  generally  relieve  the 
liotK*  sufBciciitly  to  make  him  useful;  but  in  London  it  is  often 
n«cesnry  to  destroy  the  sensation  of  the  foot  by  the  opcratiou 
of  neurotomy,  the  merits  and  demt-rila  of  which  will  be  sepa- 
rately discufised."  —  SpooHer  an  tkr  Foot,  §V.

STRUCTURE    AND    DISKASlltl   OF   TUC    HOCK   JOINT. 

This  is  a  most  importnnt  joint,  and  one  that  is  more  exercised 
than  any  other  joint  in  the  body :  lluit  is  (be  surface  of  motion 
between  its  two  larjii-  boiio«  ia  miicli  f^atcr  than  Itciwecn  any 
oilier  bones  of  iht  body.  Uuwwn  of  tin-  ItocJt  joint  have  liad 
distinct  names  applied  to  them,  by  which  thvy  are  liimiliarly 
Known,  and  il>erefore  I  will  explain  them  under  tlicM.-  tvnn*, 
which  are.  Bone  Spavin,  B<^  Spavin,  Thorouf^h  Fin,  and  Curb- 
But  previous  to  an  explanation  of  in  diaca-ie*,  n  coiKise  de- 
scription of  the  joint  may  be  useful.  'Itie  hock  ia  camjiosed  of 
six  bones,  the  pnneipal  of  which  are,  the  oa  catcis  and  tlie  astra- 
oaluB.  'I'lie  other  I'uur  bones  are  considerably  smaller,  and  have 
been  distinguished  by  names  which  need  not  liere  be  itienlioned, 
and  are  placed  in  two  rows  between  the  astragalus  and  the 
cannon,  'J'he  astragalus  is  a  very  curious  bone,  and  is  p)ace*l 
obli(|Uely  in  the  shape  of  a  pulley.  It  is  articulated  with  llw 
leg  bone,  or  tibia,  with  the  small  bones  below,  and  rather  poaM- 
rioi'ly  with  the  os  ralcis;  and  such  is  the  nature  of  these  arli- 
culations,  that  »  mod  cxtensivv  motion  is  afforded  to  ihr  »hunk. 
[The  motion  of  the  hock  is  eiitin-ly  confined  to  tlio  up))cr  urt^ 
culatton,  —  namely,  tbiil  bvlwern  tlic  astragalus  and  tftc  libia; 
the  former  bone  prftcnit  two  i-oun<l  condyles,  as  th«y  are  termed, 
with  a  deep  coiinivity  between  thcni  and  the  lower  |>art  of  the 
tibia  in  the  couniii'iwrt  of  this,  having  two  concuviijes  and  an 
cminetice  in  the  middle.  These  hones,  thus  adapted,  move  on 
each  other  in  the  manner  of  a  hinge,  having  no  lateral  motion 
btit  a  very  extensive  one  in  a  forward  direction.  'I1ie  hock 
joint  is  the  most  extensive  nnionlation  in  tlie  whole  body,  and  it 
is  protected  by  a  capsular  ligament  of  con-esponding  extent. 
This  ligament  is  favtcnvd  to  ihe  lower  end  of  the.  tibia  above, 
and  to  the  upper  row  of  small  bones  below,  and  to  the  astragalus 
on  each  side  behind  the  condyles.  At  the  upper  and  back  pari 
of  this  articulation  tiicre  is  a  moveable  cartilage,  whose  front

surface  forms  part  of  the  hock  joint,  and  hind  suifoce  the  front 
of  the  joint  capsule,  throu{(h  which  the  flexor  perforan*  t<-tidon 
poiisea  on  ihe  inside  of  the  os  calcis.  Tliia  cartilage,  which  foriiiA, 
■s  it  were,  a  part  of  the  cipsnlar  liKament  itself,  corresponds  to 
the  lower  posterior  pari  of  ilie  tibia,  and  prevents  concti^ion 
between  the  tibia  and  oa  nilcis  when  tlie  leg  is  suddenly  and 
violently  straighlencd  as  in  leapin]:;. 

The  capsular  li^mcnt,  just  itiKcnor  to  this  cartilage,  on  both 
sides,  is  the  scat  of  ihorouiili  pin,  uhiUl  i1k>  ntilcrior,  lower,  and 
internal  part  of  the  ciip»ii1ur  ii;;iimcnl  i*  the  scat  of  bog  spavin. 

T]ius  the  buck  joint,  wlwn  (he  homv  i*  ut  rrst,  may  bo  con- 
sidered to  comtist  of  two  cavities,  one  in  front  and  the  other

in  front  by  the  extensor  tendons  and  th<^  annular  ligament. 

Tlw  perforana  tendon,  we  have  seen,  enters  a  sheath  at  tlie 
upper  part  of  the  hock  on  the  inner  side  of  tW  os  calcis,  an<l 
continues  in  the  slieaih  to  ilie  lower  and  posterior  part  of  the 
hock.  This  sheath  is  sometimes  the  seat  of  inflammation  and 
lameness.  The  perforatna  tendon  expands  at  the  point  of  the 
bock,  where,  being  firmlv  bound  at  the  sides,  it  forms  a  joint 
capsule  with  the  point  of  the  hock.  This  rapsule  is  noc  the  aeat 
of  capped  hocks,  as  is  frecjiicnlly  supposed  ;  lor  cnppttl  liock  is  a 
collection  of  serous  fluid  nt  the  Ixi'k  and  outside  tlie  tendon,  and 
between  It  and  the  stronj?  incmbnviioiis  substance  undeiiicHth 
llie  skin.  The  pcrfor.itn*  tendon  below  tlie  cnpnule  becomes 
narrower  an^l  [kism-*  behind  a  Mrong  ligament,  which  extend) 
from  the  om  <'idciH  to  the  nietiic»r|>id  boiiei.  A  stmtn  of  this 
ligament  constitutes  a  curii,  altltough  the  flexor  tendons  are 
often  involved  in  the  mischief.  —  Eo.J 

Strain  of  the  Ligammlt,  tfc. 

Any  of  the  ligaments  and  leiidunt  about  tlie  hock  joint  arc 
liable  10  be  strained;  and,  if  taken  early,  ll»e  horse  rested,  and 
the  case  irrated  on  the  pviiiciplea  l)efore  laid  down,  we  »hall 
generally  ducceetl  in  eflecling  u  perfect  cure.  When  iuflamnm- 
lion  can  be  detecte<l  at  the  hock,  bleeding,  from  the  thigh  or 
aaphena  vein,  will  effect  great  relief. 

By  violent  and  long-con  tinned  exertion  of  the  Iiock  joint,  so 

f;reat  is  the  consumption  of  synovia,  in  consequence  of  its  pocu- 
iarly  extensive  motion,  that  the  synovial  membrane  becomes,  at

ing  lameness ;  the  joint,  however,  in  these  cases,  is  entirely  free 
from  inflammation,  and  the  notch,  though  denuded  of  cartilage, 
is  generaUv  covered  by  a  thin  synovial  membrane. 

These  diseased  appearances  of  both  the  upper  and  lower  arti- 
culations of  the  hock,  appearing,  as  they  often  do,  without  any 
enlargement  or  external  inflammation,  go  far  to  account  for  the 
existence  of  so  many  cases  of  obscure  lameness  of  the  hind 
extremity. 

The  only  treatment  for  theee  incurable  cases  is  the  excision 
of  the  nerve  a  few  inches  above  the  hock,  on  the  inside  only  : 
it  has  been  performed  successfully  several  times  by  Professor 
Spooner,  and  also  by  Mr.  Stanley. —  Ed.] 

Bog  Spavin, 

Bog  spavin  is  a  disease  very  common  among  young  horses, 
and  occurs  chiefly  at  the  time  of  breaking :  it  is,  of  course,  more 
likely  to  happen  when  they  are  broke  at  too  early  an  age.  The 
hock,  it  has  been  before  observed,  is  an  important  joint,  and 
designed  for  very  extensive  motion ;  but  the  motion  which  lakes 
place  in  a  state  of  nature  in  this  joint,  or  during  reasonable 
labour  of  any  kind,  is  very  different  from  that  which  is  pro- 
duced in  throwing  the  animal  upon  his  haunches,  as  it  is  called, 
in  pulling  him  up  from  a  gallop  suddenly  with  a  powerful  bit, 
or  in  taking  high  or  wide  leaps.  These  violent  motions  of  this 
joint  in  particular  are,  it  may  well  be  supposed,  likely  to  pro- 
duce this  disorder.  Bog  spavin,  then,  is  a  distension  of  the 
capsular  ligament,  by  an  accumulation  of  synovia,  formed  in 
consequence  of  the  violent  exertions  1  have  just  described,  and 
appearing  in  a  swelling  on  the  inside,  towards  the  bend  of  the 
hock. 

[When  bog  spavins  appear  suddenly,  they  are  usually  accom- 
panied by  stiffness,  and  even  lameness,  and  then  treatment  should 
be  had  recourse  to ;  but,  generally,  they  come  on  gradually,  and 
areproductivp  of  no  injury  or  inconvenience. 

There  has  been  much  difference  of  opinion  on  the  subject  of 
these  bursal  enlargements.  I'he  following  appears  to  the  editor 
to  be  their  true  nature.  The  seat  of  bog  spavin  is  the  upper 
articulation  between  the  tibia  and  astragalus,  and  it  appears  in 
that  part  of  the  joint  where  there  is  nothing  but  the  capsular 
ligament  and  the  skin  to  protect  the  joint.  The  capsular  liga- 
ment is  bound  down  by  membrane  to  the  neighbouring  parts. 
In  the  action  of  the  jomt,  when  there  is  an  abundant  supply  of 
synovia,  this  fluid  is  pressed  with  some  degree  of  force  against 
the  capsular  ligament,  and  ruptures  some  of  the  fibres  of  the 
membrane  which  confines  it.  The  consequence  of  this  is  an 
actual  enlargement  of  the  cavity  of  the  joint  itself;  it  is  capable 


of  [■ontaiiiing  more  ttian  it  did  l>erore;  and  it  is  soon  supplied 
with  Hii  udditional  quantity  of  synovia,  wliichi  pressing  against 
the  cupntiliir  ligamciii,  distends  it,  as  vre  may  perceive  in  bcw 
tpaviuK.  As  ihis  usually  takes  place  in  a  gradual  manner,  it 
•fldotn  occasions  lameness,  or,  il  ii  doe«,  it  b  of  a  temporarjF 
nature.  'I'lie  enlargemeni,  however,  continues  8s  long  as  tlit-ro 
is  sufficient  synovia  to  distend  ihe  capsule;  if  wc  blister  the  rarl 
and  keep  the  horse  on  poor  diet)  it  disappears  for  a  time,  liiere 
Ijeing  less  synovia  secreUKl :  it  reiurns,  liowcver,  with  work  and 
goodliving.  In  old  hor»es,  it  ofien  disappears  altogether,  froin 
the  diminution  of  synovia  gc«rpl<.-d. 

This  being  the  iinliirc  of  (bis  disease,  the  plan  of  opening  il

perfect  rest,  which  can  l)e8t  be  effected  by  the  application  of  a 
blister. 

Blood  spavin  is  a  fanciful  disease,  and  therefore  requires  no 
further  notice.  —  Ed.]

The  subject  was  a  race  horse  of  great  value,  and  the  thorough- 
pio  entirely  disappeared  in  about  ten  weeks.  In  some  cases,  the

Curb. 

This  is  a  swelling  in  the  back  and  lower  part  of  the  hock,  ex- 
tending from  6ve  to  eight  inches ;  the  centre  of  the  swelling 
being  about  eight  inches  from  the  point  of  the  os  calcis.  [The 
cnrb  is,  in  iis  nature,  similar  to  a  strain  in  the  back  sinews,  and 
depends  upon  a  strain  and  inflammation  of  the  strong  ligament 
that  passes  from  the  oa  calcts  down  the  back  of  the  hock  to  the 
shank  bone,  and  frequently  involving  the  flexor  sinews  at  the 
same  time.  When  the  horse  is  thrown  too  much  on  his  haunches, 
this  part  is  unduly  exerted,  and  a  strain  and  lameness  is  the 
consequence.  Some  horses  are  predisposed  to  curbs  from  the 
shape  of  their  hocks. 

If  there  be  much  inflammation,  blood  should  be  taken  from 
the  thigh  vein,  a  patten  shoe  put  on,  and  the  part  kept  wet  with 
a  cooling  lotion,  after  which  it  should  be  fired  or  blistered,  the 
former  being  by  far  the  most  effectual  plan  :  the  employment, 
however,  of  the  compound  iodine  ointment  will  be  found  of 
much  service.  —  Ed.]

WOUNDS,    BRUISES,    AND    ABSCESS. 

These  injuries  may  happen  in  various  ways,  by  kicks,  by  bttes, 
in  leaping  over  hedges  or  gates,  by  kicking  against  stalls,  and 
many  other  ways.  Various  names  have  been  applied  to  such 
injuries,  according  to  the  manner  in  which  they  are  inflicted. 
[Thus  we  have  punctured,  lacerated,  contused,  or  simple  incised 
wounds.  They  differ,-  likewise,  according  to  the  part  injured, 
whether  muscle,  sinew,  skin,  or  bone.  In  the  horse,  the  healing 
process  is  very  powerful :  the  most  extensive  injuries  heal  In  a 
abort  apace  of  time;  and  there  is  less  danger  than  in  the  human 
being  of  the  wound  becoming  unhealthy. 

Wounds  of  the  muscles  or  tlesli  heal  much  more  rapidly  than 
in  any  other  part,  whilst  those  of  the  skin  are  particularly  te- 
dious; thus,  in  many  wounds,  we  may  judge  of  the  time  that 
will  elapse  before  the  part  gets  well  by  the  quantity  of  new  skin 
required.  This  is  owing  to  the  circumstance  that  new  akin  does 
not  grow  in  the  middle  of  a  wound,  but  only  from  the  edges, 
which  thus  renders  cicatrisation  a  very  tedious  process.     New 


ekin  la  aevtr  eeftnA  witli  Ktir,  and  thus  ilir  bU-mUh  caused  by 
brokpn  kncei;  but  ihe  old  *kin  it  ufu-n,  to  a  atvat  extent, 
strrifbcd  or  drawn  over  ibe  wound  by  tlie  new  sKin,  and  thus 
llw  vxpcclicd  Uemisb  is  often  greatly  dtmtnUMI.  Injuries  of 
tmdom  or  Itgunenu  are  dower  in  healing  than  ihoecaf  muacle*^ 
from  ih«'  part  iwc  being  so  hij^hk  oi^niitMl ;  and,  for  the  same 
reason,  Utose  of  hones  are  still  more  lediofu,  ntiA  often  wilt  not 
beai  until  a  portion  exfoliates,  die^  in  faet,  and  U  otut  off. 

It  is  generally  im^^ned  ihsi,  when  an  extensive  wound  heals 
^ickly,  it  U  owin^;  to  the  virtue  of  some  particular  medicine 
employed.  This  however,  is  not  tbe  caw;  it  h  owinf^  to  iho 
powers  of  nature,  and  it  is  rarely  pcecaiary  to  do  mure  than 
assist  her  o]>crBtions. 

There  are  certain  principles  to  be  kept  in  view  in  Uio  trtal' 
mriu  of  wounds,  an  observance  of  which  will  greatly  naiuet  our 
purpose. 

In  the  first  place,  it  is  necessary  to  check  ittordioate  swelling 
and  inflammation,  altlwugh  ioAanunation,  within  certain  houndi, 
is  a  useful  process. 

Secondly,  it  is  re<|iitsile,  w)>enerer  it  be  poesibie,  lu  get  ■ 
depending  orifKi;  by  ubich  tin-  matter  can  escape  as  it  it 
formed,  otherwise  it  beconie*  arrtd  from  being  pent  up,  and, 
•ei-king  an  exit,  forms  docp-Kotcd  sinuei's,  which  greatly  pro- 
tract tlw  cure. 

lliirdly,  it  i»  CMential  tliat  tbe  external  opetiins  of  a  wound 
stx>uld  be  largi',  to  titut  it  may  not  close  uji  until  it  be  healed 
from  tbe  bottani. 

Wounds  ofcavitics.sucb  as  ibcabdomen.tbe  chest, or  the joiniA, 
must  be  treated  on  difTi-renl  principles  from  thoae  recommended ; 
xhey  must  be  closed  ax  toon  at  po«ible  ;  for  the  entry  ol'air  into 
the  abdomen  or  chest  will  be  productire  of  dangerous  inllamma- 
tion,  and  in  |)m-  latter  i>iluaii»n,  imleed,  will  prevent  the  lungs 
from  acting.  And  in  joint*  the  escape  of  synovia  will  cauw  the 
extremities  of  the  boiio*  to  rub  against  each  other,  and  thus  pro- 
duce the  nio»t  severe  and  dangerous  inflammation,  tmless  the 
wound  is  speedily  closed,  and  tlie  synovia  conline<l  to  iu  proper 
reeeplacle. 

To  carry  out  iIm^c  principles  in  (be  treatment  of  common 
wounds,  it  is  ne«-K^ry,  in  the  drtt  place,  in  nconlnxed  wound, 
to  employ  ix)uliice<,  warm  fomentation!',  or  coid  lotions,  in  order 
to  keep  intlammalioii  within  bounds.  If  any  <)irt  or  gravel,  or 
Other  loreign  subslnnce,  luu  entered  the  wound,  it  is  necessary 
to  remove  t)»cin  and  carefully  clean  (he  woniiil  with  warm  water. 
If,  however,  the  wound  Itas  been  intlicti.-d  with  a  iihnrp  iti&tru- 
iiient.  tlie  wound  itself  sWuld  not  be  fomented,  but  tbe  edgvt 
sliould  be  brought  together  and  eonliiicd  by  strong  sutures;

exit  to  the  matter  that  may  form.  If  this  can  be  obtained 
without  stitches  it  is  better  to  avoid  them.  If  the  wound  is  not 
deep,  it  U  desirable  to  hsal  it  by  the  first  intention,  as  it  is  called, 
but  it  is  rarely  the  case  that  this  can  be  done  in  the  horse.  In 
man,  sticking-plaster  assists  this  purpose;  but  the  hair,  in  horses, 
almost  precludes  its  use.  It  is,  however,  an  object  of  import- 
ance to  save  the  old  skin  as  much  as  possible ;  and,  for  this  pur- 
pose, sutures  are  often  necessary,  even  when  there  may  be  no 
chance  of  healing  by  the  first  intention.  Metallic  sutures  have 
lately  been  introduced  by  Messrs.  Simonds  and  Spooner,  with 
the  view  of  remaining  in  a  much  longer  time,  for  silk  and  thread 
usually  give  way  in  a  few  days,  leaving  a  gaping  wound. 

In  a  lacerated  wound  of  some  depth  and  extent,  it  is  fre- 
quently desirable,  if  it  penetrates  downwards,  to  insert  a  seton 
so  as  to  procure  a  depending  opening  for  the  matter  that  may 
form.  In  these  wounds,  the  lacerated  parts  may  be  removed,  as 
this  will  fecilitate  the  cure.  It  is  desirable  to  bring  on  a  healtity 
suppuration  as  soon  as  possible.  For  this  purpose,  the  applica- 
tion of  a  warm  poultice  for  one  or  two  days  will  be  useful,  if  the 
part  is  convenient  for  the  purpose,  otherwise  the  wound  may  be 
sprinkled  with  a  powder  composed  of  equal  parts  of  finely  pow- 
dered resin  and  powdered  chalk ;  inflammation  being  kept 
down  by  warm  fomentation  at  first,  and  cold  lotions  afierwards. 
When  the  wound  suppurates,  it  may  be  touched  daily  with  a 
little  tincture  of  myrrh,  and  the  following  powder  scattered  over 
it:  — 

Prepared  chalk,  powdered  ...   1  ounce. 

Armenian  bole,  powdered 2  drachms. 

Alum,  powdered  2  drachms. 

Mix. 

If  the  granulations  grow  above  the  level  of  the  surrounding 
skin,  becoming  what  is  commonly  termed  proud  JUsh,  they  must 
be  kept  down  by  the  application  of  a  little  caustic,  such  as  mu- 
riate of  antimony.  It  is  important  to  attend  to  this,  as  it  will 
materially  lessen  the  blemish.  By  this  simple  method  of  treat- 
ment, the  most  formidable  muscular  injuries  may  be  readily  cured. 

A  simple  bruise,  where  no  wound  is  inflicted,  merely  requires 
to  be  treated  with  poultices,  fomentations,  or  cooling  lotions,  in 
order  to  remove  the  infiammation  by  resolution,  as  it  is  called, 
that  is,  to  cause  its  dispersion.  This,  however,  cannot  always  be 
dooe;  suppuration  takes  place,  and  an  abtceu  is  formed.  —  Ed.] 

£  Wounds  of  llie  Salivaiy  DucU

[Wlien  a  botH- 1«  much  injured,  either  in  a  laeeraled  wound  or 
a  bruise  prochicing  an  abscess,  it  is  still  more  e9»eniial  to  make 
a  large  exU-rnal  opening,  and  to  keep  it  open  for  some  time ;  for 
Ihe  clianccs  arc  thai  a  portion  of  the  bone  will  exfoliate ;  when 
this  appi-nrs  likely  to  Uike  place,  we  may  expedite  the  process  by 
applying  a  strong  caustic  to  tlie  bone. 

I  lately  md  with  a  case  in  which  a  horse  ran  with  great 
violence  aguinit  the  corner  of  a  lamp  post,  which  caused  a  very 
deep  and  extensive  wound  in  the  breast,  and  injured  the  breast 
bone  to  such  a  degree  that  three  or  four  pieces  of  the  bone  ex- 
foliated at  different  limes  before  tlw  wound  would  heut.  'Hie 
application  of  the  caustic  proved  very  serviceable,  and  the  animal 
entirely  recovered.

Wounds  in  the  belly  may  happen  in  leaping  over  hedseSt  or 
pale  gates>  or  may  be  inflicted  by  the  bonis  of  a  cow.  Son>e- 
limes  the  strong  tendinous  covering  of  tlie  belly  is  rupiurpd, 
while  the  skin  remains  entire ;  the  gui  then  protnide*  ami  forces 
out  tlvc  skin  into  u  tumour.  This  is  a  rupture  of  the  belly,  and 
is  thought  incurable.  I  have  known  one  very  large  rupture 
cured  by  cutting  out  a  piece  of  the  sktn  which  covered  it,  and 
tbeo  sewing  up  the  wound  and  Hup|>oriing  it  with  a  bandafie. 
In  some  aecidenia  llie  »kin  also  i«  dirideiU  witb  its  pcritooeal 
covering;  the  gut  then  coinw  oui,  and  tlie  wound  is  of  a  vety 
dangerous  nature,  still  more  ao  if  the  gut  itself  is  wounded.  Tlie 
first  thing  to  be  done  is  to  put  the  gut  back,  uking  care  to  re- 
move any  dirt  or  other  matter  that  may  be  sticking  to  it;  for 
which  purpose,  should  it  be  found  necessary,  it  may  he  wasliod 
with  warm  water,  nothing  else.  If  the  gut  cannot  be  returnwl, 
from  its  being  full  of  air,  and  the  opening  in  the  belly  too  small 
to  put  it  back  again,  that  opening  may  be  cflrefully  enlarged  10 
the  iicccBiary  size.  IJut  if  the  unimul  can  Ih-  thrown  upon 
back  eonvctiit.'nily,  a  great  tleul  may  be  done  tliuc  caiiitot 
otherwise  accoiniilinlieil.  After  the  gut  is  returned,  ilie  skin 
only  should  hn  xtitchcd  up;  and  a  cushion  of  several  folds  of  okl 
hnen  and  low  being  placed  on  tlie  wound,  it  should  be  kept  in 
its  situation  by  meaiiii  ufa  wide  bandage  rolled  round  the  bodr. 
and  cJtrofully  secured.  The  animal  sliould  then  be  copiously 
bled,  an<l  have  hi*  bowels  emptied  by  clyslcr*.  'lite  only  food 
he  should  be  allowed  is  grass  or  bran  mashes,  and  tluit  only  iu 
moderate  ()uant!ty. 

IVoutidtJrom  Uwrnt  are  often  very  troublewme.  It  Is  noccntn- 
in  the  first  phwo  lo  examine  the  part  carefully,  and  extract,  with 
e  pair  of  directing  forL-t-p*  or  pliers,  every  part  of  llie  thorn  thai 
may  remain.  Whi'n  a  tendinous  part  or  a  joint  haa  been  punc- 
tured by  a  thorn,  a  very  trotdjlesome  lameness  is  sometimes  the 
consequence,  especially  when  the  thorn  lias  not  been  extracted 
immeoiately,  or  soon  after  the  accident.  Emollient  poulUcea  do 
not  always  remove  the  inflammation  produced  by  such  woundsi

been  very  lame,  and  found  that  the  two  flexor  tendons  bad

of  the  thorn,  though  probably  the  accident  had  occurred  several 
tnontlis  before.  It  U  remarkable  iliat  the  thorn  was  very  blackt

ij  be  BO  slight  as  to  occasion  little  inconvenience,  or  so 
•eriuus  as  to  render  the  animal  entirely  useless.  Between  these 
extremes  there  are  a  great  variety  of  dcgrcea. 

The  knee  con>ats  of  three  separate  articulations,  the  upper- 

of  which  i«  that  between  the  dkIIus  or  foroEirm  and  the 

row  of  bone« ;  the  next  is  that  betwet-n  the  upper  row  and 

under;  and  the  third  bittween  the  under  row  and  the  cannon 

»}uink.     Thus  there  are  three  joints  exposed   to  injury,  and 

very  near  the  suHace,  being  proteclea  only  by  the  capsular 

igamont  and  ihe  skin,  and  partially  by  the  extensor   tendons. 

r'hen   the  knei.-  Is  l>eni,  as  it  necessarily  is  when  the  animal 

fiilla,  the  joints  are  ojiened  to  the  utmost,  and  the  skin  is  drawn 

,  —  this  accounts  for  the  lact  that   in  broken  knee*  the 

ound  apiK-ars  lo  go  downwards,  and  the  internal  injury  appears 

lower  situated  than  the  extci-nal  one.     A  broken  knee  may  be 

confined  to  an  injury  to  the  skin,  or  the  tendons  may  be  lace- 

lated  and  even  divided,  or  one  of  the  joints  may  be  opened^ 

and  the  bones  greatly  injured.     Sometimes  the  ligaments  of  the 

knee  arewvercly  siniinecl  by  the  fall. 

>\^cn  the  injury  is  cunfined  tn  the  skin,  and  is  not  extensive, 
tlie  wound  may  be  covi-red  daily  with  tlie  astringent  powder  or 
paite,  l)i-fore  recommended,  and  the  knee  fretiuenily  wetted  with 
a  cooling  lotion.     A  little  work  will  not  be  iniurious. 

If  tlie  wound  be  extensive,  or  the  tenuons  injuiTd,  after 
fomenting  ll>e  part,  removing  the  dirt  or  gravel,  and  cutting  off 
^^uny  ragged  parts,  the  kuL'c  may  be  poulticed  for  a  few  days,

^Vpoulticc  may  be  prevented  from  slipping  down  by  tape  or  list 
'  passing  over  the  witbei-s.  In  a  few  days  the  knee  may  be  treated 
I  the  same  us  another  lacerated  wound,  but  sometime*  It  is  very 
desirabh-  to  insert  a  seton  through  the  lowest  part  of  the  wound,

[When  in  a  broken  knot^  iht-  joint  in  foiinil  to  be  opened, 
f^wliicb,  however,  cannot  always  be  tuC4.*rtuincd  at  first,  —  it 
becomes  a  very  serious  ufluir,  and  must  no  longer  be  treated  as 
a  common  wound.  Our  [>n)(;iKui»  in  xuch  case  will  depend  on 
tlie  cxii-nl  ol'llic  wOHiid,  |K»riii;»lurly  that  of  llic  capsular  liga- 
ment, and  on  the  circtimMiu)C«  as  to  wbeilier  infUimniation  Ivu 
been  id  «p  in  the  cavity  of  the  joint. 

In  l)ic  trfotment  of  such  eases  our  object  must  be  to  close  the 
joint  as  qni4;kly  t»  [Kissilile,  and  thus  to  pr«^-ent  the  escape  of 
synovia;  unlc^  we  succeed  in  doing  thisi  the  intlanimation  of 
the  knm*  will  {greatly  increase,  and  the  discharge  of  synovia  bo- 
come  augmented  in  quantity,  partly  ooa;;ula[ing  as  it  cscapm 
fiom  llK'knee,  and  hanging  in  large  flakes  from  ttie  wound  j 
the  iminml,  froni  the  pain  experienced,  keeps  the  knee  in  •  (wnt 
piuiiioii,  or  pawa  with  tlie  foot  continually.  A  vast  deal  of  ferer 
is  excited  in  the  system,  which  in  some  eases  wears  down  the 
animal,  and  produces  death.  In  oilwr  cases,  bony  substance  in 
thrown  out  round  the  joint,  which  at  length  clo<e«  the  wound,  but 
destroys  ibe  motion  of  the  joint,  and  renders  tlic  animal  useli^Kh, 

To  prevnit  »uch  result  we  mu»t  by  no  meiuts  keep  poulticing 
or  fom<titing  the  knw,  an  tlitK  will  only  enconmgo  tbe  diseharve 
anil  keep  up  the  irritation ;  tlte  real  soothing  niettwd  will  be  the 
application  of  styptics  or  causlica  to  the  knee.  In  many  cases,  if 
thr  o|M-ning  \*  xmall  the  application  ofllie  hot  budding-iron  will 
produce  an  eschar  ihat  will  close  the  Mvnnd;  or  if  it  be  a  punc- 
tured wound,  the  application  ofluiiar  caii^lic,  cut  to  »  point,  will 
accomplish  our  puq^se.  In  other  cose^  where  rite  injury  is 
more  extensive,  ttie  application  recommended  by  Mr.  Dawson, 
of  spirits  of  wine  saturated  with  corrosive  sublimate  several  time* 
»  day,  has  succeeded.  The  clot  of  coagulated  synovLi  sbouM 
not  be  removed  from  tlie  wound,  but  tbe  caustic  applied  round 
it.  It  may  sometimes  be  necessary  to  apply  tbe  sublimate  in 
a  solid  state,  alone  or  mixed  with  flour  or  powdered  chalk. 

It  is  very  impurtant  to  keep  the  iinimal  in  a  state  of  perfect 
qiiieiud*- ;  lie  should  be  removed  to  the  nearest  stable,  but  by  no 
means  walked  a  considerable  drxiniiev  tncr  the  accident.  Tbe 
leg  should  Im^  kept  lu  straight  as  possible,  and,  if  neceanry, 
splints  should  be  placed  at  the  back  of  ilic  knee.  Tlie  animal 
siiould  by  no  means  be  allowed  to  lie  down,  as  iliis  will  open 
the  wound  and  increase  the  irritation.  In  many  coses  it  will  be 
judicious  to  suspend  the  horse  bv  moans  of  slings.  In  sever* 
an<l  desperate  eases  it  will  be  advisable  to  adopt  tlio  [»laii

Poll  Evil. 


„  This  disease  may  be  produced  by  a  manoy  horse  rubbin;;  his 
head  under  the  manger,  and  sometimes  liJtinf!  it  up  suddenly 
when  frighlcncd,  also  by  hanj;in^  back  u|ion  liis  halter.  It  i« 
more  fre<|uvntly  produced  by  striking  the  poll  in  going  under  a 
ikarrow  doorway,  or  running  back  when  partially  got  through. 
The  part  principally  injured  is  the  sharp  ridge  of  t]ie  occiput 
and  the  neighbouring  p.irts;  and  thus  the  mischief  l>eing  so 
deep  seated,  it  is  some  time  before  the  swelling  appears  exter- 
nally, and  still  longer  liefore  the  matter  approaches  the  surface. 
The  matter  that  forms  in  consequence  being  so  completely  con- 
fined, spreads  and  renders  carious  the  under  surface  of  the 
ligtinient  of  the  neck,  as  well  as  the  posterior  part  of  the  occi- 
pital bone,  and  sometimes  of  the  ailiui  or  first  bone  of  the  ttuck 
also.  I  once  attended  the  opening  of  a  horse  that  was  never 
nuoeeied  of  having  a  disease,  but  aied  in  consequence  of  some 
accident.  On  cutting  off  the  head,  I  found  that  the  first  bone 
of  the  neck,  as  well  as  the  under  surfiice  of  the  great  cervical 
ligsuK-nt  which  passes  over  it,  were  highly  diseaKCtT.  Since  tliat 
I  have  examinm  anottier  horxc  that  died  of  an  inflammatory 
disease;  I  had  no  suspicion  of  any  disease  in  the  ligaments 
which  unite  Uie  two  firnt  vertcbru;  of  the  neck,  but  merely 
wished  to  examine  the  part.  I  found  them,  however,  in  a  state 
of  disease.  This  disorder,  then,  is  precisely  of  the  same  nature 
as  fistula  of  the  withers,  and  requires  a  similar  IrciUmenl.

not  in  the  usual  situation  of  fistula.  It  np)>enred  aa  if  about 
llie  iiftli  cvnipal  vertebra  had  been  injured.  The  wound  hsd 
been  healed  several  times  but  always  broke  out  again.  At

FRACTtHES. 


[FBACTunEa  are  much  rarer  in  the  liorse  than  in  the  human 
Gubjectf  arising,  no  doubt,  from  the  greater  uniformity  in  the 
labour  of  quaiJrupcd§,  and  from  their  being  much  less  exposed 
to  caiuahies  than  men.  Tliey  are,  however,  by  no  means  un- 
frcqucnl,  and  the  meiacarpals  and  phaliinges  are  probably  more 
expcwed  to  the  accident  tliun  tlie  other  bones,  and  ihey  likvwi^c 
admit  a  better  chance  of  euro  than  if  thi-  radius  or  the  humeniK 
in  the  fore,  or  the  tibia  or  femur  in  the  hind  extremity,  arc 
fractured  ;  from  the  powerful  muacles  attacheil  lo  thcve  bones, 
und  the  :i)ia]>e  of  the  hmb,  it  is  extremely  difficult  to  retain  tho 
partit  afterwards  in  a  proper  position  for  union,  and  in  the 
generality  of  com-h  it  i*  most  prudL-nt  to  d<-*troy  tJie  hunte.  The 
want  of  success  that  attends  the  greater  number  of  coses  of 
fractures  in  llic  hor»e,  iv  owing  to  llie  following  reasons :  —  The 
restlessness  of  ilte  animal ;  the  imjKMsibility  of  niakinfr  him 
as%ume  the  recumbent  position  as  in  a  man;  the  difficulty  of 
slinging  him  for  any  lenjjih  of  time;  the  circumstance  of  his 
linving,  in  many  instances,  used  the  limb  after  the  fracture,  thus 
displacing  the  bones  to  a  considerable  extent ;  and  the  fracture 
extetiding  into  a  joint,  or  being  very  complicated  or  SM-erc. 
7'o  ensure  a  cure,  therefore,  it  is  necessary  that  the  horse  should 
be  tractable  —  that  the  fracture  should  not  be  very  complicated 
—  that  the  home  should  not  have  walked  a  distance  on  the  leg 
aHerwards  —  and  that  the  bones  should  not  iiave  been  much 
dixplaced.  When  these  favourable  coincidences  are  present,  and 
ibe  animal  is  of  sufficient  value  to  pay  for  the  expense  of  a  few 
Booths'  keep,  we  may  then  be  justified  in  aiiempting  a  cure. 
Treatmeni.  —  There  are  many  successful  cases  of  fractures  on 
jrd,  a  full  account  of  which  may  bv  found  in  the  editor's 
ealisc  on  tlie  foot  nnd  leg  of  the  horse.  In  the  eleventh  volume

ON  THE  STHUCTUBB  ASO  ECONOMY  OF  THE  FOOT. 

It  has  been  justly  observed  that  widiout  a  sound  foot  a  hone 
is  but  of  little  value,  however  perfect  he  may  be  in  all  other 
rexpecla.  It  is  the  basis  of  the  whole  supemtrticture ;  and  when 
we  consider  what  immense  weight  is  someiinies  thrown  upon 
tliis  part  in  the  violent  exertion*  to  which  the  animal  is  expoeod, 
it  will  not  appear  strange  titat  it  should  be  so  frcqiienily,  as  we 
find  it,  alTecied  with  lameness.  It  lias  been  the  fiuliiun  for  sotne 
years  to  attribute  the  frequency  of  tlw  horse's  laineneas  to  bod 
shoeing;  but  it  is  time,  as  Mr.  Bracy  Clark  luu  observed,  (oi

all  this  idle  declamation  to  cease.  It  is  not  shocine  tiiat  causes 
the  peculiar  frefjurncy  of  lameness,  and  incurablv  laIn(^nl'ss,  in 
this  ouuntr)';  but  the  immocUratc  work  the  lionc  is  made  to  do. 
Much  has  Ix-cn  said  of  the  supL-i-iority  of  tltc  Frunch  mode  of 
■faoctflg,  and  ailiMn[iU  have  been  made  to  introduce  an  iinjirore- 
ment  on  the  French  method  into  llii«  country,  and  a  v«ry  im- 
portant imprownK-ni  it  certainly  i* ;  bill  at  to  the  French  shoe, 
oonsidt^r^l  witlioiit  the  method  of  tutilin^,  in  which  they  certainly 
excel,  I  Uiink  it  tlie  veiy  wor*t  form  I  ever  saw  in  this  country. 
As  the  diiteases  of  the  honte's  foot  form  an  esseniial  branch  of 
the  subject  upon  which  I  am  now  writing,  it  is  presumed  that 
a  brief  description  of  its  strncture  and  economy  will  not  be  un- 
acceptable lo  the  readerti  of  this  valume. 

liM're  is  not,  in  llic  whole  structure  of  tho  animal,  any  part 
so  richly  organised  as  the  foot,  althoiiglt  the  eye  ]>erha[w  may  be 
ofTcrod  as  an  exception ;  for  it  exceeds  in  the  extreme  delicacy 
of  iu  tlruclnrc  any  thing  that  can  possibly  he  imagined. 

To  a  common  observer  the  foot  may  appear  a  mass  of  in- 
•eimible  horn ;  but  it  is  compoiu^  of  an  auemblage  of  springs, 
esj>ecially  when  considered  in  n.-latioit  to  tlie  fore  leg,  which 
admirably  adapt  it,  not  only  to  the  uses  of  ilie  animal  considered 
individujiJIy,  but  to  the  uses  of  man  alto;  and  so  carefully  has 
it  been  guarded,  that  were  the  animal  cmploywl  only  to  supply 
the  neoe*.iitin  of  man,  his  feet  would  last  a»  long,  even  if  shoed, 
as  any  other  part  of  his  body.  He  tta*  t>cen  made,  howover, 
subservient  to  his  luxuries  and  that  too  in  so  high  a  degree 
tltat  he  has  materially  degenerated  from  his  original  strength 
■nd  hardihood  of  consiitution.  The  immoderate  exertion*  in 
which  he  is  now  generally  employed  arc  such  as  sufHcienily 
■ecouni  for  tlic  great  number  of  crippled  horses  iliai  are  con- 
•Uuitly  offering  themselves  to  our  notin',  especially  in  stage 
tMcbea  and  [»»(  clmises. 

In  deicribiiig  the  horse's  foot  it  may  not  be  amiss  to  take  a 
general  view  of  tlie  fore  leg,  in  which  we  sliall  find  an  assemblage 
of  large  sprinjcn,  auisting  in  the  same  purpose  however  as  those 
of  the  foot.  The  shoulder  blade  is  placed  obliquely  against  the 
•idc,  and  attached  solely  by  muscles,  by  the  elasticity  of  which 
the  body  of  the  animal,  as  well  as  the  ricUf,  is  enabled  to  bear 
thoae  violent  motions  which  must  have  otherwise  been  insup- 
portable. If  wc  look  at  the  skeleton  of  a  horse,  we  shall  be 
struck  with  the  position  of  tlie  shoulder  blade  and  the  shoulder 
bone,  each  lying  obliquely,  but  in  opposite  directions,  so  on  to 
form  an  acute  angle  at  the  joint,  and  of  course  a  considerable 
spring.  We  may  observe  the  same  admirable  contrivance  in  the 
hiod  parts,  where  the  femur,  or  thigh  bone,  forms  an  angle  with 
the  pelvis,  ami  with  the  libia  or  leg  bone,  or,  as  it  appears,  and  is 
commonly  named,  in  the  living  tior*e,  the  thigh  bone.  In  viewuig

nisF.ASES  or  the  hobse. 


the  fore  leg  of  lh«  Aniinal,  we  shall  find  in  the  oUiquilT  of  t!te 
nn.«trrn  another  powerful  spring;  and  when  we  consider  ibe 
iRMiHMise  weight  it  roust  occasionally  support,  as  in  pitching  from 
a  high  leap  on  the  ground  with  a  beaiy 
weight,  it  must  appear  asioii lulling  how 
such  a  tremendous  slwck  can  be  sup- 
ported by  so  small  a  body ;  yet  we  shall 
find  upon  examination  such  provisiooi 
M  wilt  enable  it  to  bear  any  reaeooable 
weiglii  tliHt  can  be  placed  upon  it.  If

Fig,  5.  principally  shows  the  singular  nwnner  in  which  one 
flexor  tendon  funtu  a  sheath  for  aitoilier,  thus  permitting  the 
very  f^at  extent  of  motion  these  ])arl9  possess,  without  any 
diminution  of  strength.  'I'he  sheath  thus  formed  is  lubricaieo 
wiih  synovia,  and  thus  any  penetration  or  injury  of  the  sheath 
is  a  matter  of  great  consequence,  quite  as  much,  indeed,  as  llut 
of  a  joint,  for  inflammation  of  the  most  violent  degree  is  likely 
to  follow,  and  there  is  danger  of  adhesion  of  the  tendons  taking 
place.  This  plate  also  exhibits  tlie  manner  in  which  the  tendons 
are  lied  down  at  the  back  of  the  fetlock,  also  the  expansion  of 
the  perforans  lenilon  as  it  passes  over  the  navicular  bone  and  is 
inserted  into  the  bottom  of  the  coffin  joint.  The  lateral  earli* 
lases  are  also  clearly  shown. 

Fig.  6.  exhibits  the  ligamenu  underneath  tlic  flexor  tendoni^ 
as  well  as  the  smooth  surface  al  tlie  beck  of  tlie  usainoid  bonet, 
over  which  the  tendons  pass. 

The  J^oiithpiece  is  an  iinportant  figure,  as  exhibiting,  by  a 
vertical  front  section,  the  situation  and  the  natural  colour  of  (li« 
different  parts  of  the  foot  and  leg,  and  abo  the  mainur  in  which 
the  weight  if  supported.  It  shows  the  relative  proi>ortion  sup- 
I  ported  by  the  coHin  and  ihe  navicular  bone,  nod  the  manner  in 
which  it  i*  distributed.  TIic  name*  of  tlie  different  parts  are 
given  on  the  plate  for  (Iw  convenience  of  reference.  Tiie 
various  joints  art^  di«phiyed  witli  their  capsular  ligaments,  whicli, 
in  the  nppcr  joint,  llw;  fetlock,  are  particularly  shown,  bcii^ 
&ri»ed  to  admit  the  ron.iiderahle  action  which  this  joint  pos* 
Besses.  The  coffin  joint  is  clearly  distinguished  from  the  navi* 
eular  joint  capsule,  the  former  being  m  front,  and  iIm  latter 
behind  the  navicular  bone.  The  course  of  the  back  sinews  i* 
clearly  exposed,  as  well  as  that  of  the  suspensory  ligament,  and 
the  internal  structure  of  the  bones  is  developed,  and  tJ>c  colour

plates,  difitrs  a  little  from  M.  IlonrgeUtwith  respect lo  diedegrw

Mr.  Ouutlwiti,  in  hi*  new  sj-stem  of  shoeing,  g>TM  an  explan- 
ation of  tile  advantages  anting  from  the  curved,  or  Freoch 
shoe.  "  If  we  refei',"  he  siiys  "  lo  tlw  action  of  the  fi>re  leg,  it 
will  UMid  to  explain  some  ol'  ihc  advantages  lo  be  derived  irom 
lliG  curved  shoe.  When  a  borsc  is  about  to  move,  the  (int  in- 
(Iictiiion  of  motion  is  a  bend  at  (he  knee,  which  n<.-ce«.sanly  raises 
the  heels,  and  they  become  more  and  more  elevatt-d,  till  the  toe 
(which  is  the  last  part  tliat  leaves  the  ground)  is  si»>ix,-nded  for 
the  moment  that  the  foot  is  lifted.  The  base  of  the  ftH>[.  ju«l  nt 
its  leaving  the  ground,  is  almost  perpendicular:  wIh'ii  the  knee 
is  bent  to  its  fullest  extent,  ihe  fool  is  then  In  the  same  jmsition. 
»vith  the  heels  of  the  shoe  pointin>t  upwards.  If  wo  consider 
thiii  fir^t  pint  of  ihe  motion  of  the  limb,  we  find  tin*  movement 
of  llie  toot  very  nearly  describes  a  semicircle ;  and  on  viewing 
the  form  nf  ilie  joints  connected  with  action,  ihe  necessity  for  a 
curve  at  the  toe  is  clearly  demonstrated :  again, -the  fomi  of  the 
sitoe  worn  out  a(  once  shows  that  it  must  be  moix^  stiiiable  lo 
put  on  a  new  otiu  of  that  form,  rather  than  to  suffer  the  action 
of  iIh'  leg  to  l>c  opposed  un(il  it  is  worn  to  that  form.  In  tlic 
tecond  part  of  the  action,  when  the  fool  comi-s  to  the  ground 
af^in,  the  quarters  and  hei-ls  touch  first,  and  tln-y  are  the  only 
pans  occupied  in  placing  it  on  the  ground  again.  I'bere  iiiay 
be  deviati<;iis  from  this  general  rule,  as  in  those  horses  that  have

had  action ;  also  when  Iiorsn  arc  drawin};  lieavy  woif^biH  it  niust 
iicccsianly  diflVr.  The  fore  leg*  may  be  coiiaidered  simply  as 
pillars  of  stinjwrt,  liaviiig  no  power  of  themselrm  to  propel  the 
body  forward,  progretsioii  being  entirely  [leHbrmcd  by  the  liind 

Cru.  if  it  were  noc  so,  llie  iietioii  would  be  dilfcrent,  lu  I 
ve  bi-fore  observed  it  to  be  in  those  horses  that  have  greai 
weij^his  to  draw;  and  this  may  be  more  readily  otiserved  in  any 
draught  horse  going  np  hill.  I  liave  oJteied  these  few  remarks 
Ujion  action  in  order  to  bring  the  i-eader'*  attention  to  ilie  curve 
ot  ttw  French  shoe  at  the  toe.  'i'his  form  of  &lioe  cerlainly  liar- 
moniitn  more  with  the  motion  of  the  fore  foot  than  the  EnglisJi 
does;  it  affords  a  greaier  surface  of  bearing  at  the  toe  than  the 
projecting  ridge  of  the  straight  ordinary  shoe,  and  is  much  more 
catciilated  to  allow  of  the  motion  of  the  leg  and  foot ;  the  labonr 
of  llie  muscles  is  also  dimininhed,  and  the  limb  being  in  its  na- 
tural potilion,  ihe  hgaments  have  less  imjwsed  upon  tlieni ;  they 
are  more  at  ease,  and  consequently  are  not  so  liable  to  bo 
strained.  The  sitape  of  the  coffin  hone  is  also  another  proof  of 
ihe  Fn-neii  svslem  iK-ing  more  consistent  with  the  jirinciplcs  of 
nature  than  the  straight  otdinnrv  shoe.  If  the  cottiii  bone  of  a 
fore  Rjot  bi-  placed  on  a  level  surli^ce.  the  quarters  and  hri-U  are 
Uie  only  parts  in  contact  with  it,  which  proves  thai  they  aie  in- 
tended by  nature  to  meet  the  ground  first  (quKi-e,  why  the  cur- 
vature of  the  heel  of  the  shoe  then  ?)  and  Co  bear  tlie  greater 
proiwriion  of  weight ;  but  if  the  (piarters  of  the  hoof  be  removed 
(lowen-d,  or  dimintslied)  to  admit  of  die  straight  »hoc,  ilic  por- 
tion of  weight  intended  to  be  borne  on  the  (pinrtcre  nnm  be 
thrown  upon  the  heels;  and  hence  the  t/rcat  mitc/iiff  vi\uch 
ensiles  from  the  common  (plain)  English  shoe."  I  peifi-ctly 
asrec  with  Mr,  Goodwin  as  to  the  "decided  su|teriority  "  of  the 
Irench  method  of  nailing  on  the  shoes;  but  the  curvatuiv  »f 
the  I'Vench  shoe  toward  the  heels  is  certainly  contrary  both  to 
his  own  principles  and  practice,  for  he  expressly  tclU  ns  in  the 
foregoing  quotation  that  the  quarters  and  heels  niv  intended  by 
nature  to  meet  the  ground  fnst :  and  the  plate  of  his  iinprovi-d 
Firncli  mIioc  shows  that  he  disapproves  of  the  French  curvniure 
towards  llio  heels. 

tluving  given  what  I  consider  a  sufficient  de*ciiption  of  the 
French  sJioe,  I  shall  make  a  short  remark  on  Mr,  (Goodwin's 
iinprorcmeni,  which  consists  in  making  the  qiiarters  and  heels 
on  a  le\el,  and  the  reverse  of  the  Frcncli  wlioe  with  regard  to  its 
surfncc«;  that  is,  Mr.  G.  dir«*cti!  the  foot  surliice  to  be  co»\ex, 
nnd  the  ground  surlitce  concave.  Tliis  form  of  the  fool  surface 
appear*  to  nie  to  originate  Jn  a  very  absurd  notion  with  regard 
to  the  foot :  it  wiik  thought  that,  by  making  the  surface  on  which 
the  foot  re^U  incline  or  slope  u  little  inwanls  the  outer  edge,  it 
would  promote  the  expansion  or  spreading  of  tlie  hoof,  or  at  all

1  Mievc,  U  ^llacioiis;  both  expansion  and  contraction  moM 
be  [nvvonted  by  the  nails,  as  far  as  ihey  go ;  and  if  aJiy  motion 
takes  place  in  the  horn  that  is  confinml  bv  them,  it  must  be  either 
from  a  bending  of  the  naila  or  from  their  boeomitig  loose  in  llu-ir 
■itnalions.  This  notion  of  expandinK  the  (]nBrt«rs  and  heel*,  liy 
making  tlmt  part  of  the  shoe  on  whicli  they  rest  slope  outwardt, 
is  not  only  *ery  old,  but  also  very  foolish,  in  my  opinion,  aitd 
requires  only  an  exatiiinaiion  of  the  foot,  and  a  liltiv  n-Hectinn, 
to  appear  so. 

wIk-o  the  hoof  becomes  hot  and  dry,  and  conjetpicnlly  slirink* 
or  contracts,  tliat  contraction  is  getH-rnl,  but  IhIm-s  phtLV  princi-

strongly  recommended  hy  Mr.  Osmcr,  an  eminrtit  veterinary 
practitioner  and  author,  of  this  country.  For  good  feet,  he  says 
the  xhort  shoe  is  the  best;  it  thimhl  be  made  gradually  thinner 
from  the  toe  to  the  extremities,  and  so  short  that  Imih  lite  hceU

strongly  recommend*  it  to  every  one  who  studies  tl»e  structure 
and  economy  of  the  burse's  foot ;  yet  it  has  not  been  found  to 
answer  in  general  practice.  Our  worthy  and  truly  eminent 
Professor,  Mr,  C^>lcnian,  was  strtiek  with  the  merit  of  this  shoe, 
and  tltoHght  he  had  8iiccee<ied  in  obviating  the  only  incon- 
venience tliat  belonged  to  it,  wliich  was  leaving  the  heels  up* 
covered,  and  thereby  exposing  them,  especially  in  wet  weaiber, 
to  more  wear  than  tliey  cotild  bear.     lie,  like  Lafosse,  siroiigly

pointed  out  the  necessity  of  applying  it  to  tlie  healthy  foot  only ; 
and  went  still  farther  in  showing  the  danger  of  applying  it 
suddenly,  and  without  suitable  precautions,  to  the  foot  of  a  horse 
accustomed  to  wear  thick-heeled  shoes.  He  considered  some 
degree  of  bearing  on  the  frog  necessary  to  the  health  of  the  foot, 
and  that  it  serves  also  as  a  spring,  and  as  a  stop,  to  the  animal 
in  his  various  motions.  He  found,  however,  that  by  leaving  the 
lieels  uncovered  they  were  often  worn  down  too  much,  especially 
in  wet  weather;  therefore  he  extended  the  iron  covering,  or 
shoe,  to  the  whole  of  the  crust,  that  is,  from  the  toe  to  the 
heels. 

Mr.  Coleman's  thin-heeled  sliue,  as  it  was  termed,  was  flat  on 
llie  foot  surface,  and  concave  on  the  ground  surface.  If  the 
sole  was  not  concave,  or  hollow  enough  to  admit  of  a  flat  shoe 
of  moderate  width  resting  on  it,  it  was  pared  out  sufficiently 
witli  the  drawing  knife;  and  if  the  sole  was  too  thin  to  allow  of 
this  being  done,  the  foot  surface  of  the  shoe  was  made  concave, 
and  the  ground  surfitce  flat.  The  shoe  was  made  of  the  usual, 
that  is,  of  a  moderate,  thickness  at  the  toe,  and  became  gradnally 
thinner  towards  the  heels,  and  in  such  a  degree,  that  the  toe 
was  three  times  thicker  than  the  heels.  The  principal  pre- 
caution to  be  observed  in  applying  this  shoe  was  to  pare  away 
from  the  toe  of  the  hoof  as  much  as  would  make  up  the  dif- 
ference between  the  thickness  of  the  toe  and  the  heel  of  the 
shoe,  and  thereby  prevent  too  much  pressure  upon  the  great 
tendon  of  the  foot  and  navicular  joint ;  and  if  the  heels  of  the  hoof 
were  unusually  high,  so  as  to  raise  the  frog  considerably  from 
the  ground,  ihcy  were  to  be  towered  very  gradually,  removing 
only  a  small  portion  of  the  horn  nt  each  time  of  shoeing,  until 
the  frog  had  a  bearing  on  the  ground. 

This  shoe  was  tried  in  the  army,  and  found  frequently  to 
occasion  lameness.  The  principal  trial  was  made  in  the  Royal 
Artillery,  and  I  had  an  opportimity  of  witnessing  the  effect  of  it 
at  two  different  periods.  About  twenty-three  years  since,  when 
I  was  in  the  Royal  Dragoons,  and  quartered  at  Canterbury,  I 
was  desired  by  Mr.  Coleman  to  examine  several  horses  of  the 
Royal  Artillery,  in  that  garrison,  that  wore  said  lo  lie  lame  from 
wearing  the  thin-heeled  shoe.  I  did  so,  and  was  of  opinion  that 
the  report  was  well-founded :  therefore  I  directed  the  common 
shoe  to  be  applied,  and  to  keep  the  feet  moist,  and  at  rest  for  n 
short  time,  or  until  the  lameness  was  removed.  A  few  years 
after  this,  veterinary  surgeons  were  appointed  to  the  artillery 
corps,  and  then,  I  believe,  the  thin-heeled  shoe  was  found  to 
answer  better;  for  when  I  resided  at  Exeter,  the  veterinary 
aurgeon  of  the  artillery  quartered  iii  that  district  was  transferred 
to  another  station,  and  I  was  employed  by  the  Board  of  Ord- 
nance lo  attend  the  hoi-ses  in  that  capacity;  when  I  found  that

"  Physic  and  a  bulteris,''  his  Loidship  says,  "  Jn  well-informed 
Iiuicb  would  not  be  fatal;  but  in  (he  manner  we  are  now  (1776) 
provided  with  farriers,  ihey  must  be  quite  banished.      Whoever 
leU  his  farrier,  coachman,  or  groom  ever  even  mention  anything 
more  than  water  gruel,  a  clyster,  or  a  little  bleeding,  anil  that 
too  very  seldom,  or  pretend  lo  talk  of  the  nature  of  feet,  of  The

shoe ;  for  the  crust,  instead  of  bearing  on  an  edge,  bears  on  a 
flat  surface." 

There  is  but  little  difficulty  in  adapting  a  shoe  to  a  sound 
foot ;  that  is,  a  foot  that  has  a  sound  well-formed  frog,  open 
heels,  good  bars,  strong  and  rather  concave  sole,  and  a  strong 
well-formed  crust  or  wall.     To  such  foot,  the  best  shoe  that  can 
possibly  be  applied  is  that  which  has  for  many  years  been  cm- 
ployed  in  the  Royal  Dragoons.     I  may  have  made  some  devia- 
tion from  the  form  which  was  employed,  and  so  may  others ;  but 
the  following  is  tliat  which  I  now  recommend.    The  shoe  should 
be  from  half  an  inch  to  five  eighths  of  an  inch  thick,  all  round 
from  toe  to  heel,  and  of  the  same  width,  except  at  the  heel, 
where  it  should  be  three  fourths  of  an  inch  wide.   The  nail  holes 
should  be  made  somewhat  similar  to  those  of 
the  French  shoe,   and  the  nails  driven   in   a 
similar  direction.     When  a  foot  deviates  from 
the  sound  form,  the  shoe  must  be  shaped  ac- 
cordingly.    If  the  sole  is  in  any  degree  flat 
and  thin,  the  wide  hollow  shoe  is  a&olutely 
U«"      >   necessary.* 
'Ut^nj^t'^,       if  tl'e  heels  are  tender,  and  have  corns,  the 
in   order  to  bear  bar  ahoe  IS  the  best  that  can  be  applied :  and  the 
upon  the  frog.  tender  heel,  including  part  of  the  quarter,  crust 

as  well  as  sole,  should  be  so  pared  down  as  to  be  at  tlie  dig- 

*  No  general  rule  am  be  lud  down  oi  to  either  Ihc  weight  of  the  shoe  or 
its  width,  it  must  depend  on  the  wear,  the  nature  of  the  foot,  and  that  of  the 
woric  of  the  horse.  Saddle  horses  require  narrower  shoes  than  hameiis 
horses,  and  [nrticularly  if  they  are  used  for  hunting.  The  purpose  of  wide 
■hoes  is  to  protect  the  sole  and  to  diminish  concussion ;  they  are  therefore 
necessary  toeflTect  the  former  object  in  flat  feet,  and  also  for  the  latter  pur- 
pose on  the  road. 

Tiu  Leather  Sole.  —  For  weak  feet  the  leather  sole  is  found  particularly 
■ueful.  It  is  thus  described  in  my  work  on  the  "  Foot  and  Leg  of  the 
Horse  :"  —  "It  consisti  of  a  piece  of  leather  cut  exactly  the  shape  of  the  shoe, 
covering  the  sole  and  frog,  and  applied  between  the  foot  and  shoe.  In  the 
af^icatUKi  of  the  sole  it  is  requisite,  first,  to  soak  it  in  water  a  short  time,  in 
order  to  render  it  more  elastic  and  softer,  and  to  apply  a  stopping  to  the  sole 
■o  disposed  as  to  fill  up  the  vacancies  between  the  bar  and  frog,  bo  as  to  pre- 
vent any  gravel  or  dirt  penetrating.  The  stopping  we  have  found  best  adapted 
and  most  convenient,  is  composed  of  two  parts  of  tar  and  one  of  fat 
mdted  together,  and  applied  on  tow.  Borne  little  tact  b  required  in  dis> 
posing  the  low  so  as  to  fill  up  the  vacancies  we  have  mentioned.  The  sd- 
vmntages  of  the  leather  thus  applied  are  manifold.  It  diminishes  concussion 
in  a  considerable  degree  by  its  interposition  between  the  iron  and  the  foot. 
It  preserves  the  elasticity  and  stimulates  the  growth  of  the  sole,  at  the  same 
time  that  :t  protects  it  from  the  efTcct  of  naila  and  sharp  flints.  It  preserves 
the  frog  likewise  from  injury  and  irom  undue  moisture,  the  source  of  thmaheg. 
It  strengthens  the  crust  in  weak  feet,  particularly  at  the  quarters  and  heels ; 
and  aSwds  to  the  sole  and  [rag,  when  the  surfsre  of  the  ground  is  the  least 
irregular,  that  moderate  degree  of  pressure  which  it  meets  with  in  a  stale  of 
nature."—  Ed].

may  be  removed  with  the  drawing  knife ;  the  ragged  parts  of  the 
fr<^  should  be  cut  away,  as  they  may  serve  to  narbour  dirt  or 
gravel.  If  the  toe  of  the  frog  is  very  hard  and  more  prominent 
than  the  other  parts,  it  should  be  pared  down  moderately.  Tlie 
heel  of  the  shoe  should  have  a  perfectly  flat  and  level  bearing 
upon  (he  junction  of  the  bar  and  crust,  which  should  be  rasped 
to  a  flat  surface  for  receiving  it.  The  shoe  should  never  ex- 
tend beyond  this  parL  The  wbolc  boltom  of  the  foot,  indeed, 
should  be  rasped  so  as  to  be  perfectly  flat  and  level  all  around; 
so  that  when  the  horse  stands  on  a  plane  surface,  every  part  of 
the  crust  should  bear  on  that  surface.  The  shoe  should  be  made 
level  also  on  both  surfaces,  by  the  same  crilerion,  and  then  it 
must  of  necessity  be  fitted  to  the  foot.  When  this  is  the  case, 
there  will  not  be  that  motion  in  the  shoe  in  travelling  by  which 
so  many  shining  sur&ces  are  often  worn  in  it,  and  by  which  the 
nails  are  loosened,  and  if  they  are  made  of  indifferent  iron,  or 
badly  made,  often  broken. 

The  hind  shoes  should  be  narrower  than  the  fore  ones,  and 
mode  square,  as  it  is  termed,  at  the  toe,  for  the  space  of  one  inch. 
By  making  the  shoe  aa  well  as  the  hoof  square  at  tlie  toe,  a 
steady  point  of  bearing  is  afforded  to  that  part  which  is  the  last 
to  leave  the  ground.  We  may  readily  conceive  that  as  this  is 
the  part  from  which  those  amazing  bounds  are  made,  in  gallop- 
ing and  leaping,  a  more  steady  and  Arm  point  of  bearing  will 
be  thus  afforded,  than  by  the  single  point  which  a  perfectly 
round  shoe  would  give.  They  are  less  liable  also  than  the  round 
shoe  to  interfere  with  the  fore  shoe.  The  heels  should  never  be 
turned  up  for  saddle  horses  unless  it  is  in  frosty  slippery  weather, 
and  then  it  is  an  evil  that  must  be  submitted  to. 


Fc»'  hunting  the  ihoe  must  be  narrowH  than  for  the  road,  and  an  additional 
nail  may  be  placed  on  Cbe  inaide  ;  no  evil  wilt  result  from  this,  because  in  the 
field  the  pressure  on  the  crust  is,  in  a  great  degree,  relieved  bv  the  sole  and 
frog.  There  mu^t  be  space  for  a  picker  to  pass  between  the  foot  and  inner 
fim  of  the  shoe,  but  no  more,  as  the  foot  can  then  be  withdrawn  from  heavy 
noil  with  leas  difficulty  than  when  the  usual  space  is  permitted.  To  avoid 
overreaching,  the  heels  of  the  fore  shoes  should  scarcely  project  beyond  the 
heels  of  the  crust,  and  they  should  be  rounded  off,  instead  of  being  left 
■quare,  as  is  usually  the  case.  The  hind  shoes  bhould  also,  where  there  is 
any  disposition  to  overresch,  be  square  at  the  toe,  set  a  little  within  the 
Croat;  and  the  inner  rim  at  the  toe  should  have  a  piece  cut  out,  bo  thai,  in- 
■tead  of  a  sharp  edge,  there  should  be  a  rounded  surface,  which,  of  coune,  is 
not  so  likely  to  catch  the  heels  of  the  fore  feet. —  Spooner  on  tie  Foot,^c,

-  INJURIKA   CONNRCTED  VITH   BHOEISQ,   AND   WOUNDS   OF   TOK 
W  FOOT. 

These  McWenls  moet  comniouty  arise  from  the  carelessness  of 
the  Hmilh  in  nailing  tlir  tthoe  to  ihe  lioof.  Ttte  nail  is  citluT 
driven  so  as  lo  uound  the  sensible  parlSi  or  so  near  ihem,  os  to 
occasion,  by  its  prepare,  jwin,  inflammalion,  and  in  a  fuw  daj-s, 
suppuration,  or  (tie  rDrniation  of  nmtlcr. 

When  «  »ail  is  driven  so  close  as  to  w-otnid  lite  sensible  parLs, 
ihe  animal  suddenly  draws  back  liis  fool,  from  tbe  pain  be  siif- 
fers :  and  the  smitb,  auai'e  of  w  bat  he  lias  do»e,  rrinoves  tlit- 
nail,  and  lakes  no  riiitbcr  notice  of  it;  though,  somelimos,  to 
avoid  suspicion,  he  filU  the  vncanl  bole  in  (lie  slioc  Willi  the  bead 
uf  a  nail :  and  w  lien  tlie  liorse  is  aflerwards  found  to  be  lame,  lie 
loo  oDeii  denies  having  any  knowledge  of  the  cause.  WIm'h  ihv 
lioi'M*  is  not  worked  i  in  mediately,  and  iIk'  wound  not  coi»td(>r- 
able,  it  may  not  occasion  lameness  ;  most  commonlv,  Imwi-vrr, 
it  is  of  a  moiT  serious  nature,  causing  violent  innaniinntiun, 
which  lenninale^,  in  a  few  days,  in  Miiipurntion.  'Hie  maltcr 
wliicli  is  fovmcd,  being  confined,  spreads  under  ttie  horny  soh*, 
and  cAUM-s  so  nitich  nain  that  the  Imrsc  can  scarcvly  put  big  foot 
(o  the  ground,  and  if  he  be  not  reliered,  by  giving  veiit  lo  the 
matter,  it  continues  to  spread,  and  uliimalety  oreaks  out  at  the 
coronet,  or  top  of  the  boof.  When  the  dtftt-ase  has  t>een  suffered

As  soon  as  il  n  known  lliat  a  borsc  luis  been  pricked,  as  it  is 
lermed,  in  shoeing,  if  the  smith  were  to  remove  the  horn, 
where  the  nail  entered,  with  a  small  drawing  knife,  so  as  lo 
allow  the  matter  which  may  fornt  to  escape  freely,  all  ibis  mis- 
chief might  be  avoided.  It  would  be  proper  to  let  the  horse 
stuiid  without  a  shoe  for  a  lew  days,  and  wrap  up  the  foot  in  a 
large  bmn  poultice.  Il  is  a  comtnon  practice  with  smiths,  on 
the«e  occasions,  to  pour  oil  of  turpentine  into  tlte  wound;  and, 
somtiimes,  in  order  to  increase  its  power,  ihey  set  it  on  fire;

trifling  wounds  of  the  foot,  the  horse  often  j;ets  well  under  this 
treatment,  though  more  slowly,  perhaps,  than  he  would  had 
these  remedies  been  omitted.  It  may  he  proper,  however,  to 
pour  a  little  Friar's  balsam  into  the  wound,  which  forms  a  sort 
of  coating,  and  may  serve  to  exclude  air  and  moisture  from  it, 
and  Uierehy  prevent  the  formation  of  matter:  with  the  same 
view,  the  cavity  that  has  been  made  by  reniuving  the  hum  may 
be  lightly  filled  with  tow  dipped  in  digestive  oiiilment.  But  in 
woundaufa  more  serious  nature  there  is  generally  a  high  degree 
of  inflammation,  so  considerable  sometimes  as  lo  excite  fever; 
and,  in  a  few  instances,  it  has  been  followed  even  by  locked  jaw. 
All  stimulants  should  here  be  avuidetl,  until  the  inflammation 
has  subsided,  and  matter  is  formed,  which  invariably  happens  in 
wounds  of  this  description. 

The  flrst  thing  to  tie  done  in  these  cases  is  to  enlarge  the 
opMiing  made  by  the  nail,  and  pare  away  the  hurny  sole,  on  the 
same  tfide,  until  it  yields  to  the  pressure  of  the  thumb ;  a  large 
poultice  is  then  to  be  applied.  After  two  or  three  days  matter 
will  have  been  fornied ;  and  upon  pressing  the  sole,  near  the 
wound,  a  little  dark-coloured  fluid  will  be  seen  issuing  from  it. 
On  introducing  a  probe  into  the  wound,  it  will  be  found  lo  pass 
under  the  horny  sole,  sometimes  to  a  considerable  extent;  and 
HS  far  as  the  horny  and  sensible  sole  are  separated,  so  far  is  the 
former  lo  be  removed.  A  dressing  of  tar  ointment  is  then  to  be 
applied ;  by  means  of  which  a  new  horny  sole  will  be  gradually 
produced.  Should  the  mailer  have  penetrated  lo  the  coronet, 
the  same  operation  and  treatment  are  necessary,  excepting  the 
poultice :  for,  when  the  disease  has  proceetled  thus  far,  we  may 
be  sure  ihal  there  is  matter  confined  under  the  horny  sole.  The 
sore  or  opening  on  ihe  coronet  is  to  be  dressed  with  solution  of  blue 
vitriol  or  tincture  of  myrrh.  After  being  dressed  for  three  or 
four  days  with  either  of  these  prejKirations,  Friar's  balsam  and 
B  plaster  of  digestive  ointment  may  he  used.  When  the  nail 
has  been  driven  so  near  the  sensible  parts  as  to  cause  pain  by 
its  pressure,  inflammation  comes  on  slowly  and  gradually :  and 
sometimes  the  lameness  does  not  appear  until  several  days  after 
tbcTsboe  has  been  applied.  This  may  more  properly  be  termed 
a  bruise  of  the  sensible  parts  of  the  foot,  than  a  wound ;  but  it 
produces  the  same  effects,  which  are  inflammation  and  suppura- 
tion. This  kind  of  lameness  comes  on  gradually;  and  is  often 
■o  inconsiderable  at  flrst,  that  it  is  not  observed  by  a  careless 
rider.  When  the  smith  is  consulted  on  these  occasions,  he  sel- 
dom discovers  the  seat  of  the  lameness  (unless  it  be  af^er  mailer 
has  been  formed,  when  the  cause  is  too  manifest  to  escape  his 
notice),  but  attributes  it  lo  a  strain  of  the  shoulder,  or  a  bit  of  a 
wrench  in  the  fetlock  joint.  This  is  more  likely  to  be  the  case 
when  the  smith  that  shod  the  horse  is  applied  to;  but,  if  an-

suddenly  withdrawing  his  foot  when  it  is  struck.  Tliesliofis 
then  to  be  taken  off,  and  llie  wounded  part  opened  with  t

slionid  no  tenderness  be  oliserved  in  lliu  foot,  it  would  still  bf 
advisable  to  take  oK  the  shoe,  and  apply  a  poultice  to  the  fool; 
that  is,  supposing  every  othei'  part  of  the  limb  lo  have  lieen 
careftdly  examined  also,  and  no  cause  for  (he  lameness  dis- 
covered. If  iho  lameness  shoukl  arise  from  a  wound  in  t)»e  foot, 
it  will  gradually  get  worse:  and,  when  matter  has  been  forfiied, 
the  lendeniess  is  so  considerable,  that  it  can  scarcely  fail  of  l>etng 
detected.  Sometimes  the  homy  sole,  by  which  tlie  matter  is

it  may  be  known  by  minute  specks  of  fluid  bloo4)  appearing  on

the  horn,  as  we  approach  the  sensible  sole.  This  indicates  that 
no  separation  has  taken  place  between  the  sensible  and  horny 
sole,  and  that  there  is  no  disease  in  the  part.  Supposing  this 
mistake  to  have  been  made,  whicli,  however,  is  very  unlikely  to 
be  the  case  if  the  directions  we  have  given  are  attended  to, 
the  part  is  to  be  covered  with  digestive  ointment,  and  de- 
fended from  pressure,  until  the  horn  has  grown  to  its  usual 
thickness. 


Pimctrired  Wounds. 

Tlie  horse's  foot  is  often  wounded  by  bis  stepping  on  a  nail, 
which,  in  technical  language,  is  termed  picking  up  a  nail.  The 
frog  is  the  part  generally  wounded,  and  most  commonly  on  one 
side.  When  the  nail  enters  at  the  back  or  wide  part  of  the  frog, 
that  is,  towards  the  heel,  there  is  much  less  danger  than  when 
it  enters  near  its  toe,  or  termination.  In  the  latter  situation,  the 
navicular  joint  is  exposed,  and  is  often  wounded,  causing  obsti- 
nate or  incurable  lameness ;  and,  should  the  nail  not  have  pene- 
trated so  far  as  to  enter  the  joint,  it  generally  wounds  the 
tendon  by  which  it  is  covered.  The  treatment  is  similar  to  that 
we  have  recommended  for  wounds  in  shoeing;  that  is,  opening 
the  wound,  paring  away  the  surrounding  horn,  and  poultices. 
When  the  inflammation  is  considerable,  bleeding,  bran  mashes, 
and  a  purgative,  are  useful.  After  a  few  days,  it  will  be  found 
that  the  horn  surrounding  the  wound  has  been  separated  from 
the  soisible  parts ;  when,  by  pressing  gently  on  it,  a  little  dark- 
coloured  fluid  will  be  observed  to  ooze  from  the  wound.  AH 
the  born  ttiat  has  been  thus  separated  should  be  carefully  re- 
moved, however  extensive  it  may  be.  A  dressing  of  digestive 
ointment  is  then  to  be  applied,  having  previously  poured  a  little 
Friar's  balsam  or  tincture  of  myrrh  into  the  wound.  If  the 
wound  does  not  appear  to  get  better,  but  discharges  a  thin  yellow 
fluid,  it  should  be  touched  carefully  with  the  nitrate  of  silver, 
or  lunar  caustic,  and  afterwards  dressed  with  Friar's  balsam- 
It  sometimes  happens,  however,  when  the  nail  has  penetrated 
through  the  tendon,  and  injured  the  navicular  joint,  that  the 
disease  gradually  increases,  and  at  length  becomes  so  bad,  and  so 
hopeless  a  case,  that  it  is  deemed  necessary  to  destroy  the  animal. 
I  have  seen  butiyr  of  antimony  applied  with  success  to  a  wound 
of  this  kind,  a  few  hours  af^er  it  happened,  and  am  inclined  to 
believe  that  in  all  wounds  of  tendinous  or  ligamentous  parts  a 
caustic  is  the  best  application.  J  prefer  lunar  caustic,  or  nitrate 
of  silver,  but  in  some  situations  a  fluid  caustic,  such  as  muriate 
of  antimony,  may  be  better.     If  those  wounds  are  not  immedi-

if  the  iiiioe  were  in  contact  with  it.  'n»e  method  of  detediug 
and  treating  this  kind  of  lameness  is  similar  lo  that  we  hare 
recommended  in  wounds  of  the  foot ;  that  is,  by  pressing  it,  or 
Btrikinj!  it  liglitly  with  a  hammer;  and  giving  free  vent  to  any 
matter  that  may  be  confined. 

A  horse  is  «ometimc«  ob&cr>-cd  to  be  tender  from  this  cautcv

will  acquire  its  ustml  ftrmne^ ;  but  if  t)H-  shoe  is  bearing  on  tlie 
sole,  il  must,  of  course,  be  taken  ofT  and  altered. 

1  have  known  many  cases  of  lameness  from  matter  forming 
under  the  sensible  sole,  uiiliout  any  apparent  cause.  It  is  pro- 
bable, however,  ihiil,  in  nlmost  all  these  cafic»>  it  was  occasioned

matter  was  confined,  was  completely  removed,  a  hollow  shoe 
applied,  and  the  whole  of  the  hottom  of  the  foot  covered  with 
digestive  ointment;  when  they  all  got  well  in  a  short  time. 
From  this  we  may  learn  that  when  a  horse  is  turned  to  grass 
without  shoes,  his  feet  should  be  pared  with  caution  ;  perhaps  it 
would  be  the  safest  plan,  merely  to  rasp  the  bottom  of  the  foot 
to  a  level  surface,  and  leave  the  sole  untouched.  It  must  be 
recollected,  however,  that  in  ceriain  cases  of  lameness,  thinning 
the  sole,  previously  to  the  horse's  being  turned  to  grass,  is  re- 
commended as  a  remedy. 

CoMt  2.  A  horse  that  had  been  at  grass  some  time  was  ob- 
served to  be  lame;  he  was  taken  up  and  examined  by  the  smith, 
who  could  not  find  anything  to  account  for  the  lameness,  and, 
therefore,  concluded  that  it  must  be  in  the  shoulder.  On  ex- 
amining the  foot,  J  found  a  little  moisture  oozing  from  a  small 
fissure  in  the  coronet;  and,  on  finding  the  horse  flinch,  when 
struck  on  the  bottom  of  the  foot,  towards  the  inside  heel,  1  pared 
away  the  horn  from  that  part  with  a  drawing-knife,  and  let  out 
some  dark-coloured  fluid.  A  separation  between  the  sensible 
and  horny  sole  had  taken  place  to  a  considerable  extent.  All 
the  horny  sole  that  had  been  detached  was  carefully  removed, 
and  a  dressing  applied  of  digestive  ointment.  The  fissure  in 
the  coronet  was  dressed,  at  first,  with  a  solution  of  blue  vitriol, 
afterwards  with  Friar's  balsam.  By  this  treatment  the  horse 
•oon  became  perfectly  sound. 

C€ue  3.  A  horse  had  been  fired  for  a  lameness  in  the  fetlock 
joint  of  one  hind  leg,  and  turned  loose  into  a  large  box :  about 
three  or  four  weeks  afler,  he  was  observed  to  be  lame  in  the 
other  hind  leg ;  the  smith  was  called  in  to  take  off*  the  shoe,  and 
examine  the  foot;  nothing  was  found  to  explain  the  lameness  in 
the  foot,  or  in  any  other  part  of  the  limb,  except  that  the  horse 
generally  stood  with  the  fetlock  joint  bent,  resting  chiefly  on  his 
toe.  This  was  supposed  to  arise  from  some  injury  of  the  fetlock 
joint,  as  the  position  in  which  he  stood  (ended  to  favour  the  liga- 
ments of  that  part ;  at  the  same  time  it  was  observed,  that  there 
was  neither  increased  heat,  swelling,  nor  tenderness  of  that  joint. 
It  was  supposed,  however,  that  the  lameness  was  similar  to  that 
in  the  other  leg ;  and,  as  firing  had  proved  effectual  in  that  case, 
it  was  thought  proper  to  have  recourse  to  it  in  this  also.  I  was 
sent  for  to  perform  the  operation;  and,  on  my  arrival,  being 
informed  that  the  foot,  as  well  as  every  other  part,  had  been 
already  carefully  examined,  we  proceeded  immediately  to  the 
operation.  The  horse  had  been  fired  on  the  outside  of  the  joint, 
and  turned  over,  that  the  inside  might  be  fired  also.  At  this 
lime,  a.1ittle  matter  was  observed  issuing  from  a  transverse  crack, 
or  fissure,  in  the  coronet-  This  immediately  led  me  to  suspect 
that  matter  was  confined  under  the  sole.     On  paring  it  away,

On  Lameness  frotn  Cutting. 

In  cutting,  ii  twrse  iwmdimfs  strikes  him»cir so  tovon^y, or  in 
BO  tender  a  jMirt,  (u  to  cousc  hmeona  Tor  n  *bart  Uhk-.  but 
generally  il  hooii  wctin  off,  and  Iw  goes  on  again  very  well  unui 
the  blow  is  rc|x>ated.  Wh«ii  tlw  blow  ia  inflicted  on  the  inside, 
and  lower  part  of  itio  knrr  joint,  it  is  cftlled  the  speedy  cttt, 
bpcaiiae  it  vnmnionly  bHpi>ens  whm  the  horse  is  trotting  iMt. 
'Hic  pain  this  ocvasions  is  mo  sevi^re,  that  llic  horse  often  fallH  dovn

remedied.  In  carriage:  liorM-s,  lite  l)e»l  remedy  is  to  drive  thcw 
without  u  bearing  rein,  which  enables  l)»em  to  go  with  norf 
ease,  and  without  ttiat  high  action  which  this  gagging  rein  occf 
sioni:  at  the  eame  lime  the  bitoeing  should  be  attended  to,  bjhI 
when  ihe  pflrt  of  the  fool  or  shoe  (most  freqiienltv  it  is  tilt 
former}  which  inflicts  the  injury  has  been  discovered,  it  sbonM 
be  rasped  away  as  much  aa  can  l>e  with  safety  or  proprietv. 
I  have  seen  a  severe  lameness  produced  by  a  lionie  striking  liu 
fetlock  joint,  which  continued  for  several  day*,  and  was  mistalien 
for  an  injury  of  ibe  shoulder,  because,  (hough  it  was  evident  iliu 
liorsc  bad  struck  the  fi.>t]ock  joint,  he  Iwd  not  even  knocked  ofi 
the  hair.  Upon  a  careful  examination,  1  found  he  bad  strucJ' 
tliflt  ptirt  over  which  the  nerve  passes,  and  had  left  it  so  tender 
tliat  the  horse  could  scarcely  bear  to  have  it  touched.*

eases  the  renmty  is  obvious.  The  part  most  commonly  injnml

INJURIES    CONNECTED    WITH    SHOEING,    ETC.  325 

place  it  at  a  greater  distance  from  the  striking  fooL  As  cutting, 
lioirever,  is  orten  an  eifect  of  weakness  or  fatigue,  and  not  un- 
frequently  of  awkwardness  in  going,  this  remedy  often  fails. 
Mr.  Moorecroft,  on  this  account,  was  induced  to  try  another 
method,  quite  the  reverse  of  that  I  have  just  described,  and  in 
a  few  instances  I  have  found  it  successful.  He  advises  the  outer 
branch  of  the  shoe  to  be  raised  in  the  manner  before  described, 
so  that  it  may  be  higher  than  tlie  inside.  For  lie  says,  "  When 
a  horse  is  at  rest,  he  supports  his  weight  equally  on  both  feet ; 
but  having  the  inner  heel  and  quarter  raised  wlien  one  foot  is 
elevated,  he  must  be  supported  obliquely  on  the  other,  and 
hence  have  a  tendency  to  fall  outwards ;  to  prevent  which,  he 
brings  the  moving  foot  nearer  to  the  supporting  one,  by  which 
he  strikes  it;  but  by  raising  the  outer  instead  of  the  inner 
branch  of  the  shoe,  we  necessarily  give  it  a  disposition  to  lean 
inwards,  which  will  induce  the  horse  to  throw  or  incline  the 
moving  foot  farther  from  the  supporting  foot."  • 

Mr.  Goodwin  describes  an  improvement  of  the  common  boot, 
OS  it  is  termed,  for  defending  the  fetlock  joint,  when  cutting 
canimt  otherwise  be  prevented,  which  may  be  had  at  Mr. 
Long's,  veterinary  instrument  maker,  217.  High  Holborn, 
London.f 

When  cutting  appears  to  depend  upon  weakness,  or  riding  a 
horse,  though  it  happen  to  be  a  moderate  journey,  until  lie  is 
fatigued,  the  most  effectual,  as  well  as  the  cheapest  remedy,  is 
to  turn  him  to  grass  until  he  recovers  his  strength. 

Over-reaching. 

These,  in  old  books  of  farriery,  were  termed  according  to 
their  situation  in  the  heel,  or  above  the  fetlock  joint,  the  higher 
and  the  nether  attaiid ;  from  the  French  atteiut.  These  acci- 
dents sometimes  happen  from  the  toe  of  the  hind  foot  being  too 
long  and  not  squared  off  as  1  have  advised,  but  more  frequently 
from  the  sharp  edge  afforded  by  the  inner  rim  of  the  liind  shoe 
towards  the  toe.  It  may  also  occur  from  bad  riding,  in  pulling 
up  a  horse  badly,  and  making  him  gallop  false,  as  it  is  termed. 
Whenever  the  wound  is  such  as  to  leave  a  flap  of  skin,  whether 
it  be  upwards,  downwards,  or  sidewise,  it  should  be  immediately 

*  In  the  hind  feet  there  in  no  shoe  more  likely  to  prevent  cutting  than  a 
three  quarter  shoe,  the  inside  heel  being  left  uncovered.—  Ed. 

J  The  belt  Iraot  for  cutdng  tl>c  t^  is  Torined  with  leather  fitted  to  the  teg 
laced,  the  leather  bein^  double  at  the  part  struck  by  the  other  foot. 
In  some  instances  it  is  found  that  a  boot  buckled  round  the  hoof  thnt  cuts, 
•nd  softly  stuffed,  prevents  injury  from  the  blow  when  other  methods  fail. 

For  cutting  the  fetlock,  a  piece  of  cioth  tied  round  above  the  joint  and 
doubled  down  over  it  answers  the  purpose.  — Eo,

cut  off  as  close  as  possible ;  a  reunion  o(  the  parts  can  never 
happen,  and  by  leavine  the  flap,  and  attempting  to  effect  the 
reunion  of  the  parts,  tliere  would'  be  thickening  and  a  gretter 
blemish,  and  its  removal  would  be  found  neceesary  at  last  Thk 
may  be  considered  as  a  contused  wound,  and  to  all  auch  wounds 
I  think  a  poultice  the  best  remedy.  This  probably  will  be 
doubted  by  surgeons;  but  in  horse  surgery  it  will  be  found  the 
best  practice.  WIten  the  inflammation  nas  been  completdy 
subdued  by  this  poultice,  the  astringent  paste  may  be  applieci 
and  nothing  more  done  for  two  days,  when  it  is  to  be  soaked 
and  washed  off,  and  a  similar  dressing  laid  on.  Three  or  fbor 
of  these  dressings  will  genei-ally  effect  a  cure. 

AxtringaU  Ptute. 

Finely  powdered  alum  and  pipe-clay,  in  equal  proportions; 
water  enough  to  give  it  the  consistence  of  cream.  When  tbe 
wound  is  perfectly  healed,  a  little  salad  oil  or  hog's  lard  may  be 
necessary  to  soften  the  cicatrix. 

Halter  Gut.' 

When  the  horse  entangles  his  hind  leg  in  the  halter,  he  often 
injures  himself  considerably ;  the  heel  is  the  part  that  generally 
suffers,  and  the  only  remedy  required  is  wrapping  up  the  part  in 
a  large  emollient  poultice,  until  the  inflammation  is  completely 
removed ;  if  any  sore  remains,  the  digestive  ointment,  ot 
Qoulard  ointment,  mav  be  applied  for  a  day  or  two,  and  then 
the  astringent  paste  of  pipe-clay  and  alum  mixed  with  water. 

Goulard  Ointment. 

Fresh  hog's  tard 1  lb. 

Linseed  oil 2  oz. 

Palm  oil 2  ox. 

Melt  over  a  slow  fire,  and  when  removed  and  getting  eoi^

stirring  until  it  is  perfectly  cold.

DISEASES    OF   THE    FOOT.  8S7 

CHAP.  LVI. 

DISEASES    OF   THE    FOOT. 

Corm. 

Tuia  is  a  very  common  and  a  very  troublesome  disorder,  and 
may  truly  be  said  to  be  often  occasioned  by  the  smith,  being 
eenerally  in  consequence  of  bad  shoeing.  Corns  most  commonly 
£appen  in  white  feet,  with  weak  low  heels;  but  they  are  too 
common  in  feet  of  all  colours.  They  are  occasioned  by  the 
pressure  of  the  heel  of  the  shoe,  either  by  its  bearing  directly  on 
the  sole  when  it  is  too  thin  to  bear  the  pressure,  or  by  its  forcing 
the  heel  of  the  crust  inwards.  In  this  way  the  sensible  sole  is 
bruised,  the  small  blood-vessels  ruptured,  and  the  blood  pene- 
trates into  the  pores  of  the  horn,  causing  the  dark  red  appearance 
observable  on  removing  the  shoe,  and  scraping  off  the  surface 
of  the  sole  at  the  part  marked  if  t^  fig.  I.  page  336.  This  bruised 
part  is  exceedingly  tender,  and  incapable  of  bearing  the  pressure 
of  the  shoe,  and  so  are  the  crust  and  bar  on  each  side  of  it. 

In  the  Meatmen/ of  this  complaint,  therefore,  all  the  parts  must 
be  so  cut  down,  crust,  bar,  and  sole,  situated  behind  and  on  each 
side  the  part  marked  d,  fig.  I .  page  306.,  that  when  a  bar  shoe  is 
applied,  it  may  be  full  half  an  inch  distant  from  the  heel.  In 
this  way  a  horse  will  be  able  to  do  his  work,  provided  the  shoe 
is  removed,  and  the  heel  pared  down  as  often  as  is  necessary, 
and  a  little  caustic,  such  as  buttyr  of  antimony,  applied  with  a 
feather.  As  in  this  case  the  frog  will  be  constantly  receiving 
considerable  pressure  from  the  bar  shoe,  it  is  necessary  to  take 
care  that  the  ticels  are  not  too  thick  and  inflexible,  in  which  case 
it  is  necessary  to  rasp  them  ;  and  whenever  there  is  a  morbid 
degree  of  heal  in  the  feet,  or  dryness,  they  should  be  kept  con-  . 
stantly  moist  and  cool  in  the  stable,  either  by  poultice,  or  by 
several  folds  of  old  woollen  wrapped  round  the  coronet,  and  kept 
constantly  wet.  The  common  practice  of  paring  out  the  corn, 
sad  leaving  the  bar  and  crust  to  be  in  contact  with  tlie  heel  of 
the  shoe  is  doing  no  good;  nor  would  it  afford  even  temporary 
relief,  if  the  shoe  were  not  bent  up,  or  made  to  bear  off  that 

auarter  a  little,  as  they  term  it ;  yet,  after  riding  a  few  miles, 
le  shoe  ia  sure  to  yield  to  the  horse's  weight,  and  bear  upon 
the  tender  heel.  It  is  thus  that  corns  are  made  so  troublesome 
as  we  find  them,  and  many  horses  are  rendered  nearly  unser- 
viceable, or  absolutely  ruined,  by  this  improper  treatment. 
Matter  is  often  formed  within  the  heel  from  this  sort  of  manage- 
ment, and  breaks  out  at  the  coronet,  frequently  doing  great

with  dreadful  violence  on  the  foot  that  is  sliding  innards,  gene- 
rally upon  ilic  coronet  of  the  inside  quarter.  The  injury  is  so 
considerable,  that  the  cartilage,  the  extensor  tendon,  or  ilic 
coffin  hone,  is  always  more  or  \vtt  injured.  This  is  the  enuse 
of  the  obntiniicy  of  the  disoi-dcr.  In  the  fimt  pbice,  it  is  neces- 
sary to  find  out  with  a  probe  the  direction  and  extent  of  the

^lU  is  a  disease  of  ihe  frog,  causing  a  discharge  of  matter 
from  its  division  or  cMti  not  ollen  productive  of  lameness, 
especially  in  the  hind  feet,  wliere  it  is  frequently  a  consequence 
uf  iieglij^ence  in  ihe  ^room,  in  permitting  a  hor«c  lo  stand  in  ha 
dung,  or  upon  foul  wet  litlci'.  This  sgllpns  and  rota  the  homy 
frog,  tite  putrid  and  acrid  fluids  pcnctrste  through  (he  Boakeil 
and  rotten  horn,  and  inllamc  ihv  sensible  fmg,  causing  it  lo 
discharge  a  fetid  acrimonious  matter,  instead  of  tocreting  liom 
for  its  own  defence,  as  it  does  in  the  healthy  state.

gether upon  the  cause  which  produces  it.  When  in  the  kind 
bot,  and  occasioned  by  (tlthinesa,  the  cause  must  be  removed, 
and  then  ihe  disorder  may  cea%e;  but  this  is  not  always  thecaae,

with  H  soliilioii  of  blue  vitriol,  or  osymel  of  verdigris,  Beforo 
tl)is  Is  done,  the  cleft  of  the  frog  should  be  tborougfily  cloaneed 
to  the  bottom  by  means  of  tow ;  and  if  there  is  any  ragged  bora 
covering  a  diseased  pari,  it  should  be  completely  removed.  One 
of  the^e  dressings,  when  i(  is  properly  done,  ik  tufficicnt  for  the 
cure.  Some  tar,  or  hoof  oinlmeni,  may  be  applitnl,  to  promote 
ihc  ivgeitrrution  of  horn,  mid  to  defend  it  from  moisture.  In 
canes  where  the  frog  has  In-comv  very  tender  or  rotten,  I  have 
found  it  necessary  to  npply  i>  mixture  of  tar  and  sulphuric  acid, 
which  b  made  by  adding  one  ounce,  by  weight,  of  sulphuric 
ucid  to  one  pound  of  melted  tar,  and  stirring  the  mixture  for 
some  time.  As  to  the  thrusli  in  the  fore  feel,  when  it  is  attended

fcrent :  by  attempiirig  to  stop  it  by  thoic  preparations  which  nit 
usually  employed,  the  lameness  is  ol^cn  incrraied.  The  only 
thing  to  be  done  is  to  rasp  the  licels  and  quarters,  ihin  tlic  soln,

frog  is  very  tender  and  rotten,  apply  the  mixture  of  tar  and  sul- 
phuric acid.  In  old  thrushes,  physic  may  be  useful,  and  some 
alterative  medicine.  In  bad  cases,  palliation  only  can  be  ex- 
pected,  unless  a  new  hoof  be  obtained  of  n  better  kind,  by  rasping 
the  quarters  and  thinning  the  sole,  until  spote  of  blood  appear ; 
and  then,  after  stopping  the  feet  with  tar  ointment,  turning  the 
horse  to  grass. 

Thrushes  may  happen  in  the  fore  feet  merely  from  filthiness, 
and  may  then  be  cured  as  they  are  in  the  hind  feet. 

The  third  kind  of  thrush  I  have  to  describe  is  not  so  common 
B9  the  two  former,  and  is  no  other  than  incipient  canker.  It 
may  always  be  cured  by  removing  from  the  frog  every  bit  of 
horn  that  is  detached  from  the  sensible  frog,  and  by  which  a 
diseased  part  may  be  concealed,  and  then  applying  to  the  affected 
part  a  saturated  solution  of  blue  vitriol,  or  tar  ointment,  with 
sulphuric  acid.  Cleanliness  must  be  carefully  attended  to ;  and 
when  the  disease  of  the  frog  has  been  cured,  tar  or  hoof  oint- 
ment may  be  employed  to  promote  the  regeneration  of  horn. 

Canker. 

This  is  an  obstinate,  and  often  incurable,  disorder  of  the 
foot,  generally  b^inning  in  the  frog,  and  spreading  from  thence 
to  the  other  parts,  even  to  the  coffin  bone.  It  is  often  a  con- 
sequence of  neglected  thrush,  or  grease,  but  sometimes  comes 
on  without  any  apparent  cause,  and  most  commonly  in  one  or 
two  feet,  but  sometimes  it  attacks  both  the  fore  and  hind  feet  at 
the  same  time.  I  have  now  two  cases  under  my  care-  In  one, 
the  near  fore  foot  ie  principally  affected ;  the  off  fore  and  near 
hind  foot  slightly. 

The  first  animal  is  a  fine  saddle  horse,  and  the  disorder  seems 
to  proceed  from  the  horse  standing  idle  in  the  stable  upon 
litter,  and  upon  good  keep.  The  latter  is  a  waggon  horse  uiat 
bos  been  workea  rather  hard,  and  kept  upon  oats,  chaff,  and 
beans,  with  a  small  portion  of  grains,  and  as  much  hay  as  he 
likes  to  eaL  The  saddle  horse  is  nearly  cured.  The  waggon 
horse  spears  better;  still  I  fear  that  the  disease  in  him  will 
prove  incurable.  One  thing  is  essential  in  the  cure,  and  that 
ig  to  remove  carefully  every  bit  of  horn  by  which  a  diseased  part 
may  be  concealed :  this  must  be  done  at  every  examination, 
and  the  foot  must  be  carefully  examined  and  carefully  dressed 
every  day.  The  treatment  of  canker  and  the  probability  of 
success,  depend  upon  the  length  of  time  it  has  been  standing. 
When  taken  in  hand  at  an  early  period,  and  before  it  has  ex- 
tended beyond  the  frog,  a  daily  dressing  of  a  strong  solution  of 
blue  vitriol,  and  a  stopping  of  melted  tar  ointment,  or  the 
mixture  of  tar  and  sulphuric  acid  (one  ounce  of  acid  to  oue

chalk,  has  done  good ;  also  a  solution  of  sublimate  in  tincture 
of  myrrh,  or  spirit  of  wine,'  At  every  time  of  dressing,  the 
spongy  surface  should  be  scraped  off;  and,  if  any  horn  remain 
of  the  sole  and  bars,  it  should  be  carefully  examined  in  order  to 
discover  whether  the  disease  is  creeping  under  it  or  not ;  if  there 
is  even  a  suspicion  of  its  being  so,  the  horn  must  be  completely 
removed,  and  the  diseased  part  dressed.  If,  upon  a  careful 
examination  with  a  probe,  the  coffin  bone  be  found  carious,  it 
must  be  freely  scraped  with  a  drawing  knife,  and  whatever  part 
there  may  be  in  the  way  so  as  to  impede  this  operation,  must 
be  removed.  Sometimes  the  disease  spreads  under  the  wall 
or  crust,  and  then  generally  affects  the  coffin  bone.  In  this 
direction  also  it  must  be  scrupulously  followed  with  the  drawing 
knife.  It  oflen  happens  afWr  a  great  deal  of  lime  and  labour 
has  been  bestowed  on  this  disease,  that  the  practitioner  is  un- 
expectedly  defeated  by  suffering  the  disease  to  creep  gradually 
under  the  horn  of  the  bars,  sole,  or  crust.  In  the  case  I  have 
now  under  my  care,  in  which  all  four  feet  are  cankerous,  I  have 
told  the  krrier  who  attends,  that  unless  he  dresses  the  feet  daily, 
and  observes  carefully  the  directions  I  have  given  with  regard 
to  paring  the  feet  previously  to  every  dressing,  whatever  time  it 
may  require,  his  labour  will  certainly  be  in  vain,  and  he  may  as 
well  do  DOthing.-f- 

It  is  not  unlikely  that  canker,  when  of  long  standing,  is,  in 
some  d^ree,  a  constitutional  disease ;  and,  in  this  case,  it  may 
be  useful  to  turn  the  horse  into  a  dry  field  or  paddock,  or,  at 
all  events,  to  keep  him  on  green  food. 

[It  must  be  acknowledged  that  there  are  some  cases  of  so  long 
a  standing  and  so  inveterate,  that  the  cure  is  altogether  hope- 
less, and  should  not  be  attempted  unless  the  hoi-se  is  very  va- 
luable.—Ed.] 

LaminitiS)  or  Founder 

"  Is,  as  its  name  implies,  an  inflammation  of  the  sensible  la- 
minae of  the  foot,  as  well  as  the  elastic  and  very  vascular  sub- 
Stance  that  connects  ihem  with  the  horny  laminm  and  the  coffin 
bone.  It  b  a  disease,  compared  with  other  lesions  of  the  foot,  of 
somewhat  rare  occurrence ;  but  it  most  frequently  attacks  horses 
whose  crust  and  laminae  are  weak,  and  very  obliquely  placed. 
We  meet  with  two  varieties  of  laminitis,  the  acute  and  the 
chronic  or  sub-acute. 

"  The  .SyTn^tOT/M  of  this  disease  are  a  quick  and  generally  a  full 
pulse,  accelerated  respiration,   the  feet  and  coronets  hot,  and

DISEASES   OP  THE    rOOT. 

betwMMi  this  country  and  France;  but  as  to  shooing,  it  han 
liltk'  or  nothing  at  all  to  do  wiih  it.  It  is  rntin-ly  cutiscd  by 
tho  imntoderate  work  that  horses  arc  made  to  do,  and  until 
thi«  evil  is  corrected  the  number  of  such  lamenesses  will  not 
diminish,  whatever  mode  of  shoeing;  may  he  employed. 

I  ihink  it  necessarvi  however,  to  ob3er^-e  in  this  place,  that 
a  (;reat  deal  may  be  cfone  for  the  relief  of  post  and  coaci),  aud  I 
may  add  waggon,  horses,  but  more  especially  for  the  two  former. 
They  are  generally  shod  in  the  most  slovenly  and  injurious 
manner  imaginable,  and  this  not  altc^ether  from  the  fault  of  the 
smith,  but  of  the  proprietor ;  who,  in  endeavouring  to  get  his 
work  (lone  as  cheap  as  he  can,  is  not  aware  that  lie  is  causing 
hi»  horses  to  be  crippled.  Corns  are  very  common  among  such 
horsM,  and  instead  of  being  properly  managed,  the  horse  is  com- 
pelled to  work  with  them  as  long  as  he  is  able  to  stand.  Their 
feci  arc  always  in  a  state  of  inflammation,  and  no  means  arc 
employed  for  relieving  Ibem.  The  low  price  at  which  the  smith 
works  will  not  permit  him  to  do  what  is  necessary  to  the  feet. 
He  is  sometimes  allowed,  it  Is  true,  a  eompensaiioii  in  attending 
tliem  when  ihey  break  out  at  the  coronet  from  neglected  corns, 
or  become  so  lame  from  excessive  inflammation  in  the  laminated 
substance  of  the  foot  that  they  are  unable  to  stand.  He  is  then 
permitted,  perhaps,  to  rub  in  some  strain  oils  on  the  shoulder 
or  fetlock  joint ;  or  he  may  be  paid  for  bleeding  now  and  then 
when  a  horse  is  too  full  of  corn,  or  worked  into  a  fever,  and  then 
suddenly  cooled   in  a  pond  or  river;  or  he  may  be  allowed  to 

Eve   some   cordials  wlieii   a   horse  is   exhausted  by  excessive 
bour.     But  it  is  belter  for  a  post-master  to  attend  to  a  horses' 
leet  himself,  and  pay  tl>e  smith  a  fair  price  for  his  labour. 

Clironic  lameneas  may  exist  in  various  degrees,  and  in  the 
early  stages  of  the  disorder  a  horse  may  do  considerable  work, 
by  paring  his  feet  properly,  and  keeping  them  cool  and  moist ; 
by  paring  the  soles,  putting  on  a  wide  hollow  shoe,  and  keeping 
them  stopped  with  tar  ointment.  Br  such  management,  the 
progress  of  the  disease  may  be  retarded,  and  the  norse  much 
relieved  ;  but  it  can  never  be  cured.  Most  commonly,  the  dis- 
ease gradually  gets  worse,  and  at  length  the  horse  becomes  unfit 
for  every  kind  of  work.  At  this  period  the  horse  is  generally 
blistered  or  fired,  and  turned  to  grass.  But  this  never  does  any 
good,  f^ioes  with  claws,  or  hinges  and  screws,  have  been 
proposed  and  employed  with  a  view  to  open  the  heels,  but  of 
course  they  have  never  done  any  good,  either  in  (he  way  of 
prevention  or  cure.  The  hoof  has  been  all  rasped  away,  and 
the  trarse  turned  to  grass  until  a.  new  hoof  has  grawn  down  of  a 
projier  form,  hut  ii  has  never  done  any  goo<L  That  cruel 
operation  of  tearing  off  the  sole,  teclniically  termed  drawing  the

workliiff  in  a  crippled  suite  for  «oine  iiin«>,  I  found  the  navicular 
synovial  cavity  in  a  similar  slate ;  but  Ihtc  the  coffin  joint  olio 
was  diseased.  There  was  one  part  of  tJie  articulating  surface  of 
the  coffin  bone,  where  the  cartilage  had  bc«ii  wont  away,  and 
appeared  as  an  ulcer,  and  on  the  lower  urticulatinv  ^lurbos

QIi  has  now  been  otcertainetl  tttat  lite  chronic  disease  here 
spoken  of,  which  used  ut  be  attributed  to  the  contraction  of  the

It  is  therefore  termed  the  navicular  disease.  — Eik] 

Tke  Saoiaiiar  Joint  Lamenett. 

[The  joint  above  mentioned  is  llie  seat  of  the  greater  number 
of  obscure  lamenesses  of  the  fore  extremity.  But  although  su 
frequent,  it  was  not  till  some  years  after  the  connnencement  of 
the  present  century,  that  the  nature  and  siluatioii  of  tbc  lame- 
ness was  discovered.  Before  this,  the  sliouldcrs  were  invariably 
pitched  upon  as  the  seat  of  the  disease  by  farrierw,  (and,  indevJi 
tliis  is  pretty  much  the  practice  with  tliem  at  the  present  day.) 
wliiUt  veterinary  sur;;eon»  considered  that  when  the  foot  wu 
contracted,  this  was  the  cause  of  the  lameness,  and  when  it  ms 
not,  tltBL  the  seat  of  mischief  was  llie  coffin  joint.  The  great 
merit  of  pointing  out  the  nature  and  seat  of  tlits  before  obscun

is  generally  thrust  in  a  straight  line  beyond  ihv  other,  but  some- 
times only  slightly  extended. 

Contraction  of  the  foot  is  generally  the  conseciuence  of  the 
lameuL-sa,  and  is  owing  to  the  horse  not  hearinp  llie  same  weight 
upon  it  as  before,  i^omelimea,  however,  tlie  lameness  is  pre- 
ceeded  by  coatiaction,  particularly  by  contraction  of  an  insidious 
kind. 

The  nabirt  of  this  disease  is  peculiar,  and  has  been  brought 
to  light  by  morbid  dissections.  Someiimei^  it  comes  on  sud- 
denly, and  then  llie  injury,  though  severe,  is  more  curable;  but, 
geoertilly,  it  is  gradual  and  insidious  in  its  approach,  and  is  for 
some  time  preceded  by  pointing.  In  dissecting  feet  aifected 
with  this  disease,  we  find  it  in  various  stages.  In  many,  the 
sioow  is  found  adhering  to  tlie  l>one,  in  which  cases  the  action  of 
the  joint  is  obliterated ;  but  the  case  may  remain  stationary  for  a 
long  time.  In  others  the  cartilage  is  itbradeti,  and  pariiuny  ab- 
borbed,  and  little  bony  excrescences  appenr  on  the  surface  of  the 
bone,  or  carious  holes  may  penetrate  its  substance.  In  some 
instances  of  long  continuance,  the  sinew  i«  found  excoedingly 
thin.

injured  by  a  sudden  bruiwe,  on  the  liorst.-  being  suddenly  taken 
front  this  state  of  rest  to  fast  work  on  the  hard  road.  The 
same  causes,  too,  produce  a  morbid  iliickni'^x  of  the  horny 
Bol^  with  some  contraction  of  the  hoof,  wliercby  tlie  navicular 
joint  has  a  hard  unyielding  surface  to  rest  on,  instead  of  a  soft 
cushion,  and  thus  t>eeomes  more  likely  to  have  its  synovial  mem- 
brane bruised  from  concussion. 

Tbc  trtatmfnt  of  this  disease  ia  not  generally  attended  with 
success ;  if  ulceration  has  commenced,  we  may  relieve,  but  can- 
not cure.  If  the  horse  become  suddenly  lame,  our  chances  of 
success  are  greater,  as  then  inflammation  alone  may  exist.  Tlie 
sole  should  be  pared  thin,  the  (iiiarters  rasped,  the  loe  shortened, 
and  three  to  live  quarts  of  blood  Liken  from  the  foot,  by  opening 
the  artciy  at  the  toe.  The  foot  should  then  be  immersed  in  a 
linseed  meal  poultice,  and  so  continued  for  a  week,  after  which 
a  frog  seton  may  be  inserted,  and  kept  m  for  a  month. 

If  afVer  this  treatment  the  horse  is  not  considerably  better,  wc 
may  then  despair  of  success,  unless  we  liave  recourse  to  the 
nerve  o|>eratioii,  by  which  we  may  remove  lite  lameness,  aithotigh 
we  cainiot  eradicate  the  disease. —  Ed.]

For  general  bleeding,  the  jugular,  or  occk  vein  is  most  conve- 
nient. 

The  proper  situalion  for  bleeding  is  about  four  inches  from 
tlte  part  where  the  vein  divides  into  two  brandies.  Farriers 
sometimes  tie  a  cord  round  the  neck  in  order  to  raise  tlic  vein; 
but  this  is  unnecessary,  and  may  do  mitichief. 

When  the  jiipular  vein  is  firmly  pressed  with  the  finders  of 
thu  left  hand,  the  blood  h  prevented  from  dec'ireiiding,  and  limt 
part  of  the  vein  which  is  auove  the  fingers  is  considerably  dis- 
tended, and  becomes  very  conspicuous.  In  this  Mate  it  may  be 
easily  opened  with  a  lancet  held  in  the  rigtit  hand.*  Tho  vein 
will  continue  to  bleed  so  long  as  the  pre^ure  below  is  con- 
tinued. 

Farriers  bleed  with  n  flf<tm,  which,  tlimiwh  upimrciuly  a 
clumsy  method  of  operating,  is  cerlainly  safer  than  the  1iLiici-t  in 
unskilful  hands,  f  In  topical  bU'<-ding,  a  vein  '\A  chosen  ns  near 
OS  powibic  to  the  affected  jwri,  or  the  vessels  covering  the  pjirt 
arc  Oi>cned ;  in  the  inflammation  of  the  rye,  for  eX(irTi|)le,  il  is 
doiio  by  scarifying  the  inner  surface  of  thr  eyelid,  or  by  opening 
a  small  vein,  which  is  easily  seen  going  from  the  inner  corner  of 
tlic  eye  towards  the  nose.^

When  bleeding  h  employe^l  a»  n  prrventive,  ov  in  any  tliglit 
oomplainu,  fi'oni  two  lo  tliroc  ({uarts  of  blood  niaj-  bo  (itkeit  nway, 
according  to  the  hone's  strength  and  condition;  but  in  caiii.-^  of 
internal  inflammation  or  fever,  a  more  copious  evacuation  is 
necessary. 

The  quantity  of  blood  generallv  drawn  in  inflammatory  dis- 
ordera  is  loo  smal).  It  ahould  always  be  carried  so  far  as  to 
weaken  the  pulse.  Two  gallons  may  Eometimea  be  necc-ttary 
to  produn?  this  efTecl :  and  in  mad  staggers  I  have  seeii  four 
gallons  taken  off  in  the  course  of  an  bouv  with  the  best  eflect. 

When  horses  are  taken  from  camp  or  grass,  and  put  into 
warm  stables,  they  are  very  subject  to  inflammatory  complaintx 
and  dangerous  fevers;  under  these  circumstances,  moderate 
bleeding  now  and  then  will  prevent  such  diseases.  Homes  that 
are  gelling  into  condition,  as  it  is  termed,  are  liable  lo  similar 
disorders,  unless  moderate  bleeding  be  occasionally  employed. 
J  am  inclined  to  believe,  bowever,  that  it  is  a  bad  practice  to 
bleed  ofien  upon  trifling  occasions;  it  is  liable  to  induce  p1e< 
thora  or  fuln^s  of  habit,  whereby  a  horse  is  rendered  more  siis- 
ocptible  of  disease  than  be  would  otherwise  he.  •  Moderate 
purging  and  regular  exercise,  with  a  proper  regulation  of  diet 
an<l  temperature,  are  fully  adequate  to  the  prevention  of  disease 
on  those  occasions;  but  these  are  too  often  neglected. 

It  has  been  assertt^d,  that  it  is  seldom  necessary  tn  pin  up  the 
orifice,  which  is  made  in  the  skin  by  bleeding.  1  grant  there  is 
not  ofien  any  danger  to  be  apprehended  from  its  bleeding  again  ; 
but  unless  it  be  piimed  up,  thai  is,  unless  the  lips  of  the  wound 
be  brought  into  coniaci,  and  kept  in  that  situation,  by  passing  a 
pin  through  the  edgea  of  the  skin,  and  twisting  a  little  low  round 
It,  as  is  getierally  done,  inflammation  and  swelling  will  sometimes 
take  place  in  the  wound,  and  matter  will  form  in  consequence. 

[In  pinning  up,  the  edges  of  the  skin  should  be  brought  inii- 
tnaiely  together,  and  care  should  be  taken  that  no  hair  insinuates 
between  them.  The  skin  should  be  drawn  from  ibe  vein  as  little 
as  po^^ible,  and  the  pin  should  nut  be  too  large.  For  want  of 
attending  to  these  precautions,  tliose  disfigurements  are  produced 
which  we  often  perceive  in  the  necks  of  horses  that  have  been 
bled. 

Sometimes,  after  bleeding,  the  part  swells  considerably  from 
blood  escaping  from  the  vein,  and  diffusing  itself  under  the  skin. 
The  l>est  applications,  in  these  Ciiscs,  is  cold  water,  which  should

If  J^koRtd  Vein, 

This  is  a  vciy  troublesome  complaint,  rc<|uiring  a  eondder- 
able-  (liGplay  of  lliat  patience,  of  which)  very  frequently,  tbe 
!  ovmcrhas  none  to  «paro.  It  may  commence  with  a  swelling  Jucl 
after  the  bleeding;  out  generally  (Ik  firet  appearance  is  a  little 
swelling,  and  a  few  days  aftermmls  a  M-paiation  of  the  lips  of 
tlie  wound  and  a  little  acrid  fluid  oozing  from  it.  In  slight 
cases,  matter  may  form  external  to  tlie  vein,  and  tbe  part  sooa 
gets  well,  the  vein  itself  not  being  much  aflecied.     More  fr^ 

riitly,  however,  a  considerable  swelling  takes  place,  the  vein 
vc  the  wound  feels  hanl,  end  the  parotid  gland  is  greatly  cn- 
lai^^ed.  This  denotes  a  stoppage  in  the  passage  of  the  blood, 
which  therefore  Itccomcs  stai;nutit,  and  cltukcK  up  the  roeaels 
passiii)^  through  the  gland.  When  this  occurs,  the  vein  w*ill  00- 
questionably  be  lust.  Sometimes  tliertr  is  considerable  lintnor- 
rnUK  from  (he  vein,  which  is  stop[R-d  with  some  difficulty. 

T^tatmtRt,  ^  If  (here  be  consiilerable  swelling,  and  some  healf 
the  best  plan  is  (o  foinenl  with  warm  water  the  first  day,  and  kecf 
tlie  iwellinff  vre(  witli  cold  lotion  fur  a  day  or  two  afterwards; 
by  >0  doing,  we  ge(  rid  of  a  good  di-ul  ofsu[)crficiul  enlargcnwitl, 
alihongh  the  principid  swelling  still  remains.  Wc  should  next 
blister  the  enlargement,  either  by  a  strong  application  at  ooctv 
which  may  be  washed  off  the  second  day  and  repeated,  or  bf 
freuuent  mild  blister*  in  a  liquid  form.  The  horsv  shouM  be 
tiiil  up  to  the  rack  as  much  as  possible,  so  as  lo  prevent  the  li««d 
from  being  held  in  a  de[K-nding  position.  The  diet  should  coo- 
siitt  pi'incijHilly  of  mashe)^;  hay  xliould  be  avoided,  as  it  require* 
so  niucli  mastication;  tlie  ac^llun  of  the  jaws  forcing  the  blood 
towards  thcjugular  veins,  and  Uma  incrwuing  (lie  swelling.  A 
mild  dwc  of  physic  should  be  given,  and  «  little  nitre  subwo 
quenily.  This  simpli-  mode  of  treatment  I  liave  found  effcctutl 
in  every  case  (a  vast  number)  in  wliteh  it  has  been  employed 
Tlic  vein  is  generally  lost;  but  in  llie  course  of  a  montli  (lie 
swelling  is  in  great  me-isure  abwrbed;  lite  blood  finds  olltet 
channds,  and  the  horse  in  t\t.  for  the  saddle,  and  a  few  wvekl

ii^jections,  noi  only  because  tlicy  are  uncalled  for,  but  alio  be- 
cause they  are  dangi'rous ;  they  have,  in  a  few  insiiuice*,  cnti-rrd

out  the  diseosetl  vein  or  its  contents.  In  some  instances,  there 
is  considerable  liteniorrhoge ;  when  this  is  the  casei  a  little  c-auslic 
powder  should  be  :ip|>lii<d  to  the  lips  ot'  the  wound,  such  as  suU 
phatc  of  cop[>cr ;  titui  the  horse' it  head  being  tied  up,  lit.-  sliouM 
be  kept  from  fet^ding  for  twelve  hours.  This  plan  will  g«!iieral]y 
■uccvcd  in  stopping  the  bleeding;  but  if  not,  theorilice  inu«t  be 
pinned  up,  or,  if  necessary,  two  small  pins  may  be  inserted,  and 
tow  wound  round  each. 

If  the  parotid  glund  continues  enlarged,  a  little  iodine  oint- 
ment may  lie  rubbed  in  daily  several  times.  I  have  not  found 
any  inconvenience  from  turning  horses  to  gross  subsequent  to 
the  lo««of  a  vein;  the  prindpal  evil  is  the  circumsuiice  that  wc 
cannot  bleed  on  the  aide  the  vein  is  lost. 

The  proximate  canoes  of  inflamed  vein  are  very  obscure. 
Bleeding  with  a  rusty  inscrumenl,  striking  too  hard,  cutting 
through  or  acrntss  tlie  vein,  badly  pinning  up,  neglecting  to  tic 
up  the  bead,  rubbing  the  nwk  afterward?,  have  all  been  consi- 
dered as  causes:  but  it  has  Wen  found  that,  when  thc«e supposed 
agents  have  been  puiijosely  tried,  tlicy  have  failed  tn  producing 
an  inflamed  vein ;  whilst  it  has  occurred  when  the  operation 
has  been  properly  performed,  and  every  precaution  exercised. 
It  must,  however,  be  confessed  that  it  occurs  much  more  fre- 
quently when  the  operation  is  performed  In  a  bungling  manner, 
and  proper  means  neglected  afterwards.  It  may,  however, 
depend^  m  some  measure,  on  l)>e  slate  of  the  atmosphere;  for, 
at  some  periods,  the  disease  is  much  more  frequent  than  at 
othcre;  and  tt  may  also  Iw  influitnced  by  tlie  constitution  of  the 
animal,  li  has  h<-en  a  matter  of  sur]>rise  that  the  swelling 
should  almost  invariably  exten<l  towards  the  bead  in  inflamed 
jugular  vein ;  but  this  is  produced  by  the  blood  being  rendered 
Blagiiaiit  at  tills  [urt,  and  not  below ;  ibe  inflaminalion  probably 
docs  not  extend  more  in  one  direction  tlian  the  other;  hut  as 
soon  «  it  is  sufficient  to  produce  a  stoppage  in  tlie  vein,  it  of

Cltfsterg, 

This  useful  and  innocent  mode  of  exhibiting  medicine  is  too 
much  neglected,  and  when  employed  is  frequently  done  in  a 
slovenly  and  ineflectual  manner.  The  usual  apparatus  is  a 
pewter  pipe,  about  14  inches  long,  and  an  inch  in  bore,  to  which 
a  large  pig's  or  bullock's  bladder  is  firmly  tied.  The  apparatus 
invented  by  Mr.  Read  affords,  however,  by  fiir  the  best  method 
of  administering  a  clyster.  Any  quantity  may  thus  be  given, 
and  with  a  moderate  force  only.  An  opening  clyster  is  made 
l^  mixing  a  handful  or  two  of  salt  with  four  or  five  quarts  of 
warm  water :  to  this  a  little  hog^  lard  or  sweet  oil  should  be 
added.  Linseed  tea,  or  thin  gruel,  with  a  little  treacle  or  sugar 
makes  a  good  emollient  clyster.  And  an  anodyne  or  opiate 
clyster  is  made  by  dissolving  from  one  to  three  or  four  drachms 
of  crude  opium  in  three  or  four  pints  of  warm  water.  This  last 
kindof  clyster  is  employed  in  locked-jaw,  especially  when  it  is 
found  impossible  to  give  medicine  by  the  mouth.  In  this  case, 
nourishment  must  be  given  also  in  clysters.  Nourishing  clysters 
are  made  of  broth,  milk,  rich  gruel,  and  sugar.  It  was  observed 
by  Gilnon,  that  when  nourishing  clysters  are  given  in  locked- 
jaw,  they  are  sucked  upwards  by  the  bowels,  and  absorbed  into 
the  blood.  He  sustained  a  horse  a  considerable  time  in  this 
way.  I  have  seen  clysters  sucked  as  it  were  upwards  after  the 
pipe  has  been  withdrawn,  which  is  evinced  by  the  rumbling 
noise  made  in  the  bowels  soon  after,  and  the  plentiful  discharge 
of  dung,  evidently  from  the  colon.  The  stimulus  of  a  saline 
clyster  in  flatulent  colic  seems  to  be  propagated  by  the  nerves  of 
the  bowels,  throughout  the  whole  almost  of  the  alimentary 
canal. 

Blisters. 

Before  a  blister  is  applied  the  hair  must  be  cut  off  from  the 
part  as  closely  as  possible.  The  blistering  ointment  is  then  to 
be  well  rubbed  into  the  part  with  the  hand ;  and  afler  this  has 
been  continued  about  ten  minutes  some  of  the  ointment  may 
be  smeared  on  the  part.  In  blistering  the  legs  the  tender  part 
of  the  heel,  under  tne  fetlock  joint,  is  to  be  avoided,  and  it  may 
be  better  to  rub  a  little  hog's  lard  on  it  in  order  to  defend  it 

*  If  the  purging,  however,  should  be  excewive,  we  may  treat  the  case  aa

not  twisted  tight,  but  made  6exible,  like  a  bell-rope,  and  about 
six  yards  in  fengch.  One  end  of  the  rope  is  to  be  firmly  and

and  upwarcb,  wlilcli  causes  him  lo  fall  more  quickly.  Oii«  nmn 
slioulu  sund  at  the  rump,  on  the  Icfl  side,  (o  push  him  whi-n 
ttie  legs  are  drawn  up  together ;  and  another  should  liold  hini 
Meadily  by  (lie  head,  standing  in  front  of  hitn ;  and  as  soon  ax 
the  horse  is  down  that  man  should  throw  liimself  on  the  neck,  and 
incline  the  nose  upward  by  iifiing  iht-  halter;  thus  he  can  keej> 
the  head  and  neck  down  without  difficulty, 

M.  Girard,  in  his  TraiU  dit  J'ictl,  has  proposed  an  improve- 
ment in  throwing  horses,  which  is  very  simple,  and  should  always 
be  employed.  If  t)ie  horse  is  to  be  thrown  on  the  right  side,  a 
long  piece  of  web  or  a  rope  is  to  be  liu;tcncd  round  the  right  foi'e 
arm,  close  up  to  the  elbow.  The  oilier  end  is  then  to  be  passed 
over  die  withers,  and  Ik'M  at  a  litlk-  distance  by  one  or  two 
men.  The  force  which  is  applicil  in  this  way  will  cause  the 
borse  to  fall  more  readily,  and  with  more  certainty,  and  exactly 
in  the  situation  where  he  is  required  to  be  thrown.  This  con- 
trivancr,  therefore,  is  extremely  useful  in  confined  places,  where 
tliere  is  jti«t  room  enough  to  throw  a  horse,  and  no  more.*  The 
horse  Ix-itifj  thrown  down,  and  liis  legs  closely  dinwii  together, 
the  end  of  the  hobble  rope  i*  lo  Ih-  pfiiuieil  under  the  hobble 
rings,  between  the  fori-  and  hind  leps  and  «eciired  with  a  liileh 
as  it  is  termed,  so  that  Im  cannot  separate  ibem  again  until  llie 
hobbles  are  unbuckled,  and  then  they  all  may  be  taken  away  at 
once,  and  the  horse  suffered  to  gel  up.f 

In  letting  the  horse  gel  up  again  the  hobbles  must  be  un- 
bucklvtl  caotionsly,  beginning  with  the  under  fore  and  hind  one. 
TlK-se  should  be  unbuckled  gently,  and  not  jerki-d,  m  thai 
would  caii»>  the  horse  to  struggle,  and  render  it  difficult  to 
take  them  off,  or  the  leg  might  get  loose,  and  he  may  thus  hurt 
one  of  the  a«>-istants  who  btippens  to  be  standing  incautiously 
within  the  stroke  of  his  fore  or  hind  leg.  J  I  haw  ween  hobbles 
in  which  llie  longnes  were  moveable,  so  ihm  by  drawing  them 
out  with  a  poir  ofptnceri  the  hobbles  were  all  lukect  ofl'ut  onoffx 

In  performing  ojH-r.itions  upon  tlicliurseit  is  not  only  necessary 
to  throw  him  ilown  as  I  have  described,  but  in  liring  the  out- 
side of  the  fore  leg,  for  vxainple,  in  the  pHMeni,  the  bubble  mint 
be  taken  off  and   the  leg  securi-d  by  means  of  a  web  passed

may  be  found  in  Bouigelat's  •'  Essai  sur  les  Appareils  et  sur  los

Another  method  is  commonly  employed  in  throwing  down 
cattle.  A  long  rope  is  doubled,  and  tied  in  a  bow  at  the 
doubled  end,  of  sulncicni  size  to  go  over  the  animal's  head,  and 
rest  at  (lie  bottom  of  his  neck  like  a  collar.  The  two  ends,  of 
equal  length,  arc  then  to  be  brought  down  between  the  fore  and 
bind  legs,  and  one  of  llio  end«  round  each  hind  leg.  The  ends 
of  the  rope  arc  now  drawn  forwards  on  both  sides,  by  which  the 
hind  legs  are  so  <irawn  up  under  the  belly,  that  he  is  easily 
pushed  down,  and  must  then  be  secured.*

Bt'nOICAL  OPERATIOSS. 


[thickening,  and  contraction  of  the  skin,  and  tlius  occnaiofu,  in 
•ome  defrree,  a  permanent  bandage.  It  produces  coiuiderable 
pain,  ana  leaves  a  blemisl) :  it  therefore  sliould  Dot  be  employed 
vniiecesiiarily,  but  when  had  recourse  to,  it  should  be  done 
ellii:iiinily. 

This  operation  is  sometimes  performed  standing,  but  goniTally 
the  horse  is  thrown.  For  curbs  ringbones,  and  whenwer  the 
auriace  to  be  fired  is  inconsidenihle,  and  the  animal  is  lolenbly 
steady,  we  may  fire  standing,  the  horse  being  secured  with  the 
aide  line  for  the  hind  leg,  and  one  foot  hela  up,  when  tlic  ton 
leg  is  operated  on.  A  twitch  s)>ould  alwavs  be  used.  In  other 
cases,  the  horse  may  be  cast,  which  is  (ho  safest  method,  and  the 
legs  secured  in  the  manner  belore  stated. 

The  firing  iron  should  have  a  smooth  round  edge,  nearly  ai 
thin  as  tlie  edge  of  an  old  shilling.  The  skin  shoidd  never  be 
penetrated ;  but  the  cuticle  sliould  b«  destroyed,  and  a  dark 
Drown  impression  left  on  the  skin,  from  which  there  will  be  a 
glutinous  exudation  soon  after  tlie  operation,  when  the  iron  has 
bwn  properly  applied.  'I'hf  hair  sliould  be  cut  off  from  the 
part  previously  to  the  oiH'ralioii,  as  closely  as  possible. 

Messrs.  Turners  advise  for  many  cases  to  fire  quite  through 
the  nkin,  which  they  find  far  more  cfTeclual  than  the  common 
metiiud.  'Dh'  irritation,  by  this  plan,  is  kept  up  much  longer, 
and  the  benefit  i*  greater,  an<)  it  will  no  doubt  succeed  in  rt- 
liiovinj;  liiitiencM  in  many  ca»c«  whi-n  the  iituiil  plnn  will  alto- 
gcllii'r  tikil.  It  is  liable,  however,  to  con^ideruble  objection,  on 
account  of  the  long  time  ncci'ssary  to  keep  the  horse  in  tin.' 
stable,  and  also  from  the  great  blemish  it  produces.  To  obviate 
these  objections,  and  at  tlie  same  lime  to  derive  il>c  benefit  of 
deep  firing,  I  Jiavi-  been  in  the  habit  of  penelrnting  the  skin 
with  a  small  pointed  iron  in  nitmcrotis  places,  cither  on  the  fired 
lines  or  without  them,  according  to  the  nature  of  the  case.  Thi» 
plan  I  have  found  to  create  little  or  no  blrmi^sh,  end  is  yet 
aticntk'd  with  considerable  advantage.  A  horse  may  or  may  not 
he  bliitlered  after  firing,  according  to  the  degree  of  irritation 
we  wiiih  to  pio<Uice.  There  is  much  diflcrcncc  of  opinion  as  lo 
the  bwl  direction  for  drawing  ihc  lines  in  firing,  some  pre- 
ferring a  vertical,  others  a  horizontal,  and  some  an  oblique 
direction.  The  first  plan  is  the  best  adapted  for  forming  a 
bandage,  the  second  for  leaving  little  blemish :  but  for  my  own 
part,  lor  ordinary  purposes,  I  prefer  the  third  or  feathered  form, 
conceiving  that  it  unites  the  advantage*  of  both  allowing  tt»> 
hair  to  cover  the  mark,  as  in  horizontal,  and  lorming  a  bandagi- 
As  in  vertical,  firing.  It  is  a  bad  plan  to  cross  the  line,  as  iliiti 
bolates  the  skin,  itud  is  thus  likely  to  increaae  tl>e  blemish. — En-] 


NICKINO.  057 


Niekinp. 


This  operation  is  now  seldom  performed :  it  consists  in  weak- 
ening or  destroying  the  power  of  the  flexor  muscles  of  the  tail. 
This  IS  done  by  making  two  or  three  iransverse  incisions  on  the 
nnder  part  of  the  tail,  through  the  skiti  and  muscles.  The 
lioTse  should  be  thrown  down  for  the  purpo§c,  or  put  into  what 
is  termed  a  break.  Tlic  first  ineiRion  should  be  about  two  or 
three  inches  from  the  origin  or  basis  of  the  tail,  continuing  it 
from  one  of  the  sides  where  the  hairy  part  terminates,  lo  the 
otli«r,  and  tiuito  down  to  the  bone,  except  in  tlic  centre,  where 
ihe  kkin  only  should  be  divided.  There  are  some,  however, 
who  go  deeper  than  this,  by  which  there  i»  more  bleeding.  The 
second  incision  should  be  made  in  a  siniiljir  manner,  and  three 
inches  dtxtani  from  the  first,  and  to  widi  the  tliini.  On  making 
the  second  incision,  ihe  ends  of  tht;  muscles  will  protrude 
through  the  first,  and  must  be  drawn  out  with  forceps,  and  cut 
off;  tlie  same  with  the  second.  This  being  done,  it  is  itsual  to 
place  Iwndages  round  the  incisious,  and  ilien  put  the  tail  in 
what  iB  n-rniL-d  a  pulley,  which  may  Iil-  -leen  in  the  sinhles  of 
hoi-sc-dealers,  and  need  not  be  descrilx-d.  Tlie  weight  first 
applied  to  keep  the  tail  up  should  be  moderate,  not  exceeding 
three  pounds;  and  it  is  necexmry  the  following  nioniing  to 
loosen  the  bandages,  or  cut  them  through  on  Uie  back  part  of 
the  tail.  By  negTecting  this  precaution,  a  serious  and  even  fatal 
inflammation  has  taken  place.  In  about  three  days  matter  will 
form,  and  then  the  bandages  will  fall  off.  They  must  on  no 
account  be  forced  off;  but  the  loose  ends  may  be  cut  off  with 
scissors.  A  large  gaping  wound  will  then  appear,  but  it  re- 
quires no  kind  of  dres&ing,  and  is  generally  completely  filled  up, 
and  sometimes  cicatrised  in  about  aixteen  days,  or  three  weeks. 
About  the  third  or  fourth  day  aficr  nicking,  the  weight  employed 
to  kei-p  the  lail  up  should  be  increased  to  six  or  seven  pounds; 
and  the  iransverse  line  upon  which  the  pulley  runs  may  be 
|>lac4'd  a  little  further  back,  so  as  to  bring  tlie  tail  a  little  ox-er 
llie  Ixick,  After  a  week,  the  horse  may  l»e  led  out  for  exercise, 
and  if  he  carri<^«  Ins  tail  on  one  side,  the  pulley  on  the  irans- 
vAve  line  should  be  so  conhned  as  10  draw  the  tail  in  a  contrary 
direction,  for  a  sufficient  time  to  make  him  carry  it  straight. 
The  tiuw  of  kwping  the  horse  in  die  pulh-y  i»  from  three  weeks 
to  a  month. 

^This  cruel  and  unnecessary  operation  has  now  gone  into 
genermi  disuse  in  England,  though  it  is  still  practised  in  Indand,

pastcm.  and  no  pwUcular  appearance  of  tnjuiy  about  the  fet- 
lock joint*. 

The  horse  being  thrown  down  and  secured,  according  to  the 
direction*  f^ven  under  that  head,  an  incision  is  to  he  made 
through  tlie  skin,  three  inches  above  the  most  prominent  part 
of  tlie  fetlock  joint,  when  viewed  sideways,  and  just  within  the 
Bexor  taidon,  or  hack  sinew,  as  repre§ented  in  the  plate  of  the 
nerve  operation.  The  incision  having  been  carried  quite 
through  the  skin,  the  white  cellular  membrane  will  appear; 
this  must  he  carefully  hHed  up  with  the  forceps,  and  as  carefully 
and  gradually  dissected  offi  and  then  the  nerve  will  appear 
(as  represented  in  the  figure).  As  soon  as  the  nerve  is  seen, 
a  tenaculum,  or  a  large  crooked  needle,  armed  with  a  little 
small  twine,  is  to  be  passed  under  it,  from  within,  outward, 
in  order  to  avoid  puncturing  the  artery;  and,  with  (he  same 
view,  the  point  of  the  needle  may  be  blunted  in  the  most 
trifling  degree.  A  needle  should  be  made  for  the  puqjosi-,  not 
quite  so  crooked  as  iJicy  commonly  arc,  and  curved  only  towards 
its  extremity.  The  needle  then  may  be  taken  out,  and  the 
ncrvebeinKgenllyliftcd  lip  with  the  twine,  the  cellular  membrane 
underneath  may  be  enijipcd  away  with  a  pair  of  sciMors,  or 
with  a  knife,  can-fully,  so  as  to  admit  of  a  slender  curved  bis- 
toury being  passed  under  it  without  touching  the  nerve  with  the 
e<lge;  as  soon  as  this  i?  done,  ami  the  nerve  cleared  up  to  the 
highest  part  of  the  incision,  llie  pmbe-poinlcd  curved  bi*toury 
13   to  be  puMerl  under  it  at  the  Iiiglicst  i»ari,  and  the  iii'rve 

auickly  divided  by  a  drawing  kind  of  a  stroke.  This  is  necessary 
lat  the  nerve  miiy  be  divided  with  a*  little  violence  as  possible: 
for,  when  tt  i«  done  with  scissors,  or  by  lifting  the  knife  directly 
tip,  or  with  a  knife  ihai  doeii  not  cut  writ,  a  thickening  will  re- 
main at  the  upj)er  extremity  of  the  divided  nt-rve,  with  consider- 
able lendemesa;  and  when  this  hnpjK-iis  to  In-  slriick  in  g"iiig, 
it  gives  ibe  horse  intolerable  pain,  and  makes  him  go  lame  for  a 
short  time.  The  nerve  cannot  be  divided  with  too  keen  an  in- 
strument, or  loo  gentlv.  The  division  of  the  nerve  causes  great 
but  momentary  [min,  like  that  of  an  electric  shock,  apparenily, 
and  the  horse's  struggling  at  tluit  moment  must  be  guarded 
agaitut :  but  as  soon  as  it  is  done,  the  pain  of  the  operation  may 
be  coiwidcred  B8  over :  the  inferior  portion  of  nerve  is  then  to 
be  laid  bold  of  by  the  forceps,  and  from  an  inch  to  an  inch  and 
a  half  cut  out.  Die  skin  may  be  closctl  with  one  stitch,  for  no 
bandage  or  drt-ssing  is  required.  For  the  first  four  day$,  the 
leg  should  be  sponged  several  times  a  day  with  tepid  water;  on 
the  fifth  the  stitches  will  give  way  and  the  wound  will  o]>en, 
but  thin  mui«t  not  be  attended  to.  No  kind  of  dressing  is  neces- 
»ary  ;  the  wound  will  be  completely  liealed  in  four  weeks,  and

the  operator  is  to  grasp  the  testicleii  with  hi»  hund,  ho  that  the 
skin  over  the  testicle  may  be  tense  and  eaiiily  divldt-d,  an  JnciMoii 
is  t]ien  to  be  made  through  the  skin,  about  three  inchcH  in 
ltfn$;th,  rather  more  than  leas.  He  Is  then  to  proceed  gradimlly 
with  his  knife  until  a  little  fluid  or  water  issues,  by  whicli  he 
may  be  sure  that  the  vaj,'Lnal  sac  is  opened.  Into  this  opening 
one  of  the  blades  of  a  pair  of  scia^ors  is  to  be-  introduced,  and 
when  this  is  done  the  vaginal  sac  is  laid  open  with  the  scissors 
to  the  same  extent  as  the  incision  in  the  skin.  The  testicle  now 
comes  readily  out,  and  after  a  litde  tini«,  when  the  cremaater  or 
retractor  muscle  has  relaxed  sufficiently,  the  cord  is  to  be  placed 
between  the  dam;,  so  that  the  whole  of  the  testicle,  willi  the

the  pain.  The  clams  must  be  made  very  tight,  or  the  cord  will

made  with  a  piece  ofold  rldrr  fiv«  or  «tx  iiichos  long  and  an  inch 
in  diameter;  this  must  be  split  in  two  and  a  notch  made  half  iin 
inch  frgm  each  pndsufEcicntly  deep  to  hold  ilie string.  Thepiili 
is  thrn  taken  from  the  wood,  and  itie  vacancy  filled  witi)  a 
pWtcr  composed  of  flour  and  corrogive  sublimate.  Mr.  Good- 
win coniiidtfrs  the  caustic  quite  useless,  and  thus  recommends  the 
operation  to  be  performed.  — "  The  horse  bvinjt  si-cured,  and 
tho  ncci'ssary  instrument*  itt  liund,  the  operator,  laying  hold  of 
the  near  testicle  and  drawing  it  out,  sufficiently  to  render  the 
scrotum  tense  und  secure  the  cord,  iniikcs  his  incision,  through 
the  scrotum  and  tunicu  va|rinii]i«,  if  the  operation  be  the  unco- 
vered one;  the  ttsticle  presenting  itself  is  to  be  cautiously  laid 
hold  of  by  the  omrator,  having  given  tip  die  ktiife;  »t  this 
moment  tl»c  twitcli  should  be  lightened  on  llie  nose  to  pm-eni, 
if  possible,  the  animal  struggling  during  his  efliirt;  caution 
must  l>e  used  merely  to  aupjiort  ilii.'  testicle,  and  not  to  mukc 
the  same  pull  on  it  as  nlien  the  cremaster  muscle  h  acting. 
Having  obtained  the  testicle  sufficiently  out  of  the  scrotum  to 
place  the  clam,  the  assistant  should  do  this  by  opening  and 
putting  it  on  the  anterior  part  of  the  cord.  At  this  part  of  the 
operation  the  Russians  generally  cut  through  the  vas  deferens. 
When  the  clam  has  been  placed  on  the  cord,  the  operator,  giving 
up  tlte  teiticle  to  the  care  of  the  assistant,  should  be  cuutious 
titat  no  jiarts  of  the  scrotum  are  included  in  it,  and  then  uike 
the  open  ends  of  the  clams  in  his  right  hand,  having  disengaged 
erery  thing  with  the  left ;  the  assistant  then  brings  the  einl  of 
the  clam  together  by  his  pincers,  taking  care  to  keep  iliem  chuv 
to  tlte  horse  at  the  moment  of  his  strugi^ling.  The  ends  being 
secured  by  a  double  round  of  strings  and  tied,  the  generality  of 
practitioners  take  away  the  testicle  by  cutting  through  the  cord 
at  about  the  distance  of  half  an  inch  from  the  clam.  Otherit 
allow  them  to  remain  on  till  the  clam  be  taken  off,  as  a  matter 
of  security  from  second  Imemorrhage.  The  clams  must  have  n 
sufficient  degree  of  pressure  completely  to  stop  the  circulation  in 
the  pan,  yet  not  so  great  as  to  lacer.ite  ihc  vessels.  If  pressiirv 
be  made  inefficiently,  the  animal  sutfers  severely  from  it ;  on  llie 
other  hand,  the  pressure  being  properly  mnde,  he  suffers  less 
than  in  any  other  way  of  operating. 

Mr.  Goodwin  thus  describes  the  uncovered  operation,  to  which 
be  gives  tlie  preference :  — 

**  After  opening  the  scrotum  and  dissecting  through  the 
dartos,  which  is  very  readily  done  by  passing  the  knife  ligJitly 
uver  its  fibres,  the  testicle  and  its  covering,  the  tunica  %'nginalis, 
must  be  taken  in  the  right  hand,  while  the  left  should  be  rnr- 
ployed  in  puling  back  the  scrotum  from  its  atlBchmrni*)  and, 
having  your  assistant  ready  as  before  with  the  clam,  it  must  be 
placed  wotl  above  the  epididymis,  and  greater  pressure  b,  of

infktnniadon.  He  has  also  tried  the  uncovered  roetlMKl  with 
equal  sucoees,  at>d  gives  it  the  preference,  for  the  reason  before 
BUIed. 

The  operation  hy  ligatart  is  not  frequently  practised,  bario;! 
gone  into  disrepute  for  many  years  in  consequence  of  the  opert- 
tion  having  been  pi-rformed  by  Mr.  Cline.  tlie  celebrated  surgnw. 
and  followed  by  in  Ham  mat  ion  and  deaili.  It  is.  however,  lo  be

really  il>c  caute  of  death,  for  wc  Bnd  that  tbe  li>;ature  bos  bceii 
employed  by  wrnic  veterinary  suf]g(«iiK  for  nuiny  years  with  tbe 
best  t-ITcctK.  Mr.  Kichard  Collier,  of  Dublin,  nye  that  he  boi 
adopted  it  for  thirty  year*,  and  it  lus  b»i*n  very  Nuocessful.  He 
thu*  d<-j«ribc«  hi«  nietiiod  of  operating  in  tltc  I3tb  volumeof  llie 
yelerinariaR  :  — 

After  M-curing  the  hor»e  on  hi»  b«ck,  1  open  the  itcrotum  in 
the  ujtiul  wny,  and  let  out  ll>c  ti'«ticle.  I  then  ptxce  the  iron 
clams  on  the  ord,  ami  divide  it.  This  being  done,  I  take  bold 
ofa  small  portion  of  it  with  the  forceps  (embracing  the  artery. 
of  couree),  and  apply  the  ligature.  **  I  generally  hare  oii 
lutiistant  ready  with  tlu.*  ligature  made  into  a  noose,  wbo  placet

(MTt  of  the  operation." 

Mr.  C  frequently  bleeds  afterwards,  and  gives  a  laxative. 

Mr.  Dray,  of  Leeds,  statoi,  in  dte  same  number  of  tbe  t'ftf 
rinarian,  tliat  he  employs  the  ligature  in  castration.  After 
easting  llie  hoixs  he  Miy* :  —  "I  then  procet>d  to  remove  the

bren  inlroctuced  by  Messrs.  Daws,  SJiiioiids,  aiid  Wardle,  and 
is  Uins  di^cribrd  by  Hr.  Daws :  —  "  Tho  operation  of  castration 
by  tortion  is  pcrfortm-d  as  follows :  —  An  incision  througli  the 
•crotuin  on  one  *'kU'  is  lir«l  mattv  with  \hv  scal[K-t  suffici<?iiily 
Intf^  to  admit  iho  fn-r  ncapv  of  the  twlicle;  the  vas  deferens 
is  tb<-n  divided  with  titr  tame  instrument  abntit  iiti  iiicli  above 
the  cpidydimis.  Hy  pnroiiin^  this  plan,  the  rei'istaiicc  of  the 
<;remastfr  muscle  will  bv  def«-al<.-tl ;  and  the  testicle,  with  its 
vesM-ls,  will  lie  in  a  r|uivt  ttatv  until  the  conclusion  of  the 
operation. 

A  longitudinal  incision  is  now  to  be  inndc  through  the  tun!ca 
vjiffinnli"  rdlcxa,  and  a  [mrlion  of  the  siK-rmalic  artery  laid  bare, 
and  fre«-d  from  its  adjacent  attachments.  The  torsion  forceps 
is  then  to  be  nppHed  to  the  artery,  which  should  be  divided  in 
that  portion  imnH-diatWy  below  the  grasp  of  the  instrument,  the 
thumb  and  index  finger  of  the  left  hand  pressing  back  the  blood 
in  the  vessel.  The  artery  is  then  to  he  twisted  by  the  forceps, 
held  in  the  right  hand,  nniil  the  elasticity  n  de&(royed,  and  it 
will  no  longer  recoil,  but  remain  curled  np  in  b  knot.  The 
torsion  forceps  may  then  be  removed  witu  safety,  and  the 
remaining  portion  of  the  cord  should  be  divided,  and  returned 
wrtliin  the  scrotum.  Should  the  hcemorrhage  from  the  artery  of 
the  cord  prove  at  all  troublesome,  it  may  be  arrested  in  a  similar 
manner.  The  number  of  twists  will  depend  upon  the  size  of 
the  artery,  from  four  to  six  revoJutiouB  bemg  sufficient  for  small, 
and  eight  or  ten  for  larger  vessels.  The  effect  which  torsion 
pi-oduce5  on  the  vea^l,  independent  of  destroying  its  elasticity, 
is  a  laceration  of  its  internal  tunic,  the  edges  of  which  become 
speedily  agglutinated  by  means  of  plastic  lymph:  a  clot  of  blood 
plugs  up  the  end,  so  tliat  the  obliteration  is  rendered  doubly 
secure."  This  description  is  followed  by  numerous  cases,  in 
wliicli  tills  method  of  operating  has  been  practised  by  tlie  tliree 
practitioners  before  mentioned  with  success. 

The  use  of  torsion  as  a  mode  of  slopping  the  hiemorrhage 
from  arteries  was  introduced  by  Mr.  Costello  in  iS24,  and  for 
many  operations,  particularly  ia  cutting  out  tumours,  it  has  been 
employed  with  great  advantage.  The  present  writer  has  em- 
ployed it  for  this  purpose  with  the  best  enects;  but  for  castration 
h«  does  not  consider  that  it  has  any  advantage  over  tlie  ligalure, 
iban  which  it  must  certainly  be  less  secure. — Eu.]

otlier,  when  it  tales  place  at  any  other  part  ot  tlie  abdomra. 
The  latter  is  called  ventral  hernia,  and  generally  arises  froni 
blows,  kicks,  or  falls  bjr  which  ihe  psrietes  of  the  abdomen  are 
rnptuivd,  and  thus  form  an  opening  through  wliich  the  boweli 
pflAs,  aiid  are  only  prevented  e«ea[Hng  by  ihe  skin.  The  former 
variety  has  different  names,  according  to  the  part  io  which  the 
gut  is  found  ;  tlius,  if  it  rvaclbea  the  scrotum,  it  is  called  scrotal. 
or,  in  tlie  gelding,  inguinal  hernia.  There  are  numerous  other 
■ubdi visions,  which  it  is  unnecessary  here  to  notice,  but  whidi 
may  be  found  trt-atrd  at  lengih  in  Girard's  '•  Treatise  on 
Hernia,"  translatctl  by  Mr.  Percirall,  in  the  I'etfrhiariait,  anii 
also  in  a  very  pxcelleni  paper  read  by  Mr.  Simoiids  before  llic 
V.  M.  Association,  and  reported  in  tlte  I'Jth  volume  of  the  Ft- 
itrinariem. 

Hernia  eometimefi  becomes  sfrangtilated,  in  which  case  llic 
inleetines  arc  tightly  pressed  by  the  stricture;  anfl*  if  not 
relieved  by  opetaiion,  mortihcaiion  and  death  are  sure  to 
ensue.  Scrotal  hfinia  is  more  likely  to  bccon>e  stnuigulalrd 
than  any  odier,  from  the  snialliiess  of  the  opening  ihrnngh 
whici)  llio  gut  escapes.  From  the  general  practice  of  c*Mfv 
lion  in  this  country,  it  b  comnaralivelv  rare;  but  in  Indisi 
where  it  is  common  to  use  entire  Iwrses,  the  disease  is  of  freqiNtK 
occ-iinence.  Mr.  Rogers,  who  has  pracli^cd  some  yeora  1> 
liulis,  thus  describes  the  symptoms  and  the  operation  in  tfte  IM 
volume  of  the  P'eterinaruiit :  —  "A  horse  is  brought  in  from  llw

and  others  generally  needed  in  castration.  ICvery thing  being 
in  readiness,  the  operator  places  himself  on  his  knec<  in  the  rear 
of  the  horec,  and  commence*  an  examination  externally  wid  by 
the  rectum,  by  which  means  he  i»  generally  able  to  nscennin  the 
iiaiure  of  the  hernia.  He  then  takes  the  lesiicle  of  tlie  affected 
Bide  in  both  bands,  nn<),  mnnipulnting  it  so  as  carefully  to  bring 
it  in  close  contaci  with  the  scrotum,  leaves  it  in  the  leU  band. 
Tightening  ibe  skin,  and  guided  by  llic  raplie,  he  makes  a  free 
incision  through  ttie  integuments,  and  then  tlnoiigh  ibe  tunic,

means  of  the  scissors  or  scalpel,  fir»t  inlrodueing  one  of  his 
fingers  us  a  guide.  If  the  operator  hii-i  a  knowlt^lge  of  tlie  parts, 
he  needs  not  to  bo  ulVuid  of  opening  the  nei'oluin  by  free 
incisions,  made  with  camion.  On  opening  the  «crouiiu,  n 
quantity  of  serum,  depending  on  the  length  ot  time  the  strangu- 
lation has  existed,  will  escape. 

If  the  operator  lakes  the  testicle  firm  in  his  baud,  there  will 
be  little  danger  of  wounding  the  gut. 

After  having  opened  ibe  scrotum,  by  putting  aside  the  testicle, 
he  may  generally  oblnin  a  view  of  tlic  intestine.

by  which  is  meant  tlie  return  of  the  hernial  part,  by  the  band,  inro 
the  cavity  of  the  belly.  If,  after  a  ihorouRh  examination  of  the 
parts,  reduction  bnng  considered  |>racltcable  and  profitahle,  no 
time  should  be  lost.  Sbould  the  animal  quietly  submit,  the  oper- 
ation stiould  be  performed  while  he  is  standing,  by  introducing 
one  hand  into  the  rectum,  and  drawing  up  the  protruded  gut ;  in 
cases  of  resistance  or  difficulty,  however,  it  is  beet  to  cast  our 
patient,  and  then  wc  may  work  with  both  hands  at  the  sanae 
lime,  —  one  in  the  rectum  drawing  up  the  f^t,  and  the  other  in 
the  dteath  gently  forcing  it  into  tlw  abdomen,  'llie  operator 
will  only  recollect  that  force  in  drawing  up  the  gut  is  to  be 
avoided  as  much  as  possible,  the  consequences  too  often  being 
inflammation,  gangi'i^ie,  and  nipliire.

the  administration  of  the  opiate:  her  respiration  and  other  vital 
functions  seemed  not  to  be  interfered  with.

v'nhrr  s'lAe  of  each  jaw.  and  situated  belween  the  molar  and  in- 
ci^or  tc^Ui.  In  marea,  the  tushes  are  generally  absent,  and 
sonKriimea  there  are  a  f^w  supplementary  teeth. 

The  teeth  are  placed  in  »ery  deep  soelcets  in  the  jaw-bones,  by 
wliicli,  with  the  assistance  of  the  gums,  they  are  firmly  kept  in 
llieir  situation. 

Thf  structure  of  llie  teeth  is  very  curious;  in  the  horse  we 
riml  it  composed  of  three  poriions :  first,  the  bone,  or  ralher  the 
ivory  for  it  is  similar  to  the  tusks  of  the  eleplianl,  forms  the 
bulk  of  [he  tooth :  secondly,  the  enamel,  whicli  is  exceedingly 
hiircl,  nnd  forms  the  surface  of  the  crown  mid  a  portion  of  the 
face,  mid  dips  into  the  body  of  the  tooth  ;  thirdly,  the  criista 
|K*iro«t,  soflcr  than  the  oilier  portions,  and  more  opake ;  this 
pnriimi  iippcnrs  to  be  a  sort  of  cemcnl  to  unite  the  olhci'  coii- 
»litu<'nt«  together,  but  it  is  only  found  in  herbivorous  animals. 

In  Uie  fcctus  of  three  or  four  months  old  wc  find  the  germ  of 
the  l^rst  pair  of  teeth  in  the  alveolar  cavity.  It  appears  a  soft 
pulpy  nuhstancc  secreted  by  a  membrniioo*  cajKulc,  which  in  an 
iitcisor  inotli  h  single ;  but  in  the  molar  there  arc  no  Kt*  than 
four  to  till-  under  and  five  to  the  upper,  which  accounts  for  the 
irregular  jippi-iiruricc  of  the  molar  teeth.  The  pulp  is  gradually 
changed  into  the  hard  material.  The  membrane  of  the  incisor 
teeth  that  sccrclcd  the  pulp  is  double ;  and  from  its  outer  sut^* 
face  it  afterwards  secretes  the  enamel,  and  from  its  inner  the 
tt'ory.  A  tooth  is  divided  into  the  crown  and  the  faug  ;  the  I'or- 
mer  being  that  portion  outside  the  gum,  an<l  the  latter  thnt  con- 
tained within  the  socket ;  whilst  the  part  immediately  embraced 
by  ilie  gum  is  called  tlie  neck.  The  ui)p<T  sur^e  of  the  crown 
is  called  the  face,  and  is  that  part  on  which  the  mark  is  situated 
in  tlie  inciior  teeth,  by  which  wc  judge  of  the  age. 

The  hontc  luis  two  sets  of  teeth,  the  temporary  and  the  per- 
muneiit :  the  former  are  considerably  smaller  and  whiter  than 
the  latter.  The  tushes,  however,  are  permanent,  and  do  not 
»p[>ear  till  after  four  years  old. 

The  iwrniaiient  incisor  teeth  are  too  inches  and  upwards  in 
length:  their  liue  present* a  deep  funnel-like  cavity,  which  ex- 
tvntln  some  di>tnnce  into  the  interior  of  the  tooth,  and  consti- 
tutes what  is  called  the  mark.  The  interior  of  the  tooth  is  nUo 
provided  with  a  cavity  that  communicates  with  tlie  twltom  of  Uie 
socket  by  an  opening  at  the  end  of  the  root.  (See  page371., 
fig.  12.)  The  looth,  therefore,  when  young,  is  nearly  hollow; 
but  both  cavities  diminish  with  age.  The  lower  one  is  filled 
with  a  gelatinous  substance,  which  contains  the  nerves  and 
vetsels  by  which  the  tooth  is  nourished.  The  nrrangt^nienl  of 
the  ivory  and  the  enamel  in  the  inciaor  teeth  deserves  ]iarticular 
consideration.  "  The  enamel,"  »ays  M.  Gii'ard,  "after  having 
ci«ered  the  entire  of  the  external  surface,  doubles  itself  towanis

eiiilly  un  tlie  »idc  correspojiding  to  the  anterior  ed^'o  of  the  tooth.* 

A«  tltc  animal  advances  in  age,  this  otiier  cavity  becomes  ol>> 

liieratvd,  and  the  infundibulum  ia  then  only  surrounded  by  a 

mans  of  ivory,  much  tliicker  anteriorly  than  posteriorly. f 

Defore  that  of  fire  years  old,  the  ago  of  tbc  horse  is  ascertained 
by  the  preneiice  or  disappMranee  of  the  temporary  teeth  ;  and 
iirom  live  to  eight  by  the  diaappearance  of  ine  niark  which  is 
commonly  supjiosed  to  be  filled  up ;  but  in  fact  disappears  by 
the  borders  ot  the  cavily  being  worn  down.  It  takes  about  three 
years  to  wear  the  teeth  down  to  tlie  bottom  of  these  cavities; 
thus,  the  anterior  teeth,  being  first  formed,  are  first  to  lose  their 
mark  ;  the  middle  teeili  tollowing  the  next,  and  the  corner  teeth 
the  succeeding  year.  The  French  distinguish  the  incisor  leeih 
by  calling  the  anterior  ones  tlie  nippers,  ihe  corner  tbc  corner*, 
and  those  between  ihem  the  dividers;  which  terms  will  serve  to 
disthiguish  them  in  this  place.  When  the  incisors  first  appear, 
the  anterior  Imrder  of  the  mvity  is  somewhat  higher  tliaii  the 
piiMcrior  internal  border;  but  in  the  course  of  a  year  it  ia  worn 
down  level. 

For  many  years  it  lias  been  euatotnary  to  judge  of  tlie  age  bjr 
ll>c  marks  wv  have  mentioned ;  but  at  eight  years  old,  the  ooret 
I  is  said  to  be  aged ;  and  after  this  time  it  was  considered  to  be 
in)|>0MtI)le  to  OKcerrain  the  age.  Thei'e  are,  however,  niber 
means  which  enable  u»  pretly  generally  to  judge  of  tlie  age,  if 
not  with  certainty,  »i  iiiiy  rate  a)>proBching  to  it.  If  we  take  nB

In  ihifl  couniry,  for  yi-are  pasi,  it  lias  been  customary  lo  reckon 
I  the  o^  of  horses  from  llie  first  of  May,  slthough  they  may,  in 
nuiy  imlancca,  be  foaled  several  montlis  eitlicr  before  or  after 
l))U  date.  It  has  however,  within  these  few  years,  been  Ae- 
citied  by  the  jockey  elub  that  the  ages  of  race  horses  shall  l)f 
reckoned  from  the  Ut  of  J^iniiary.  They  are  generally  foaled 
earlier  than  other  horses,  it  being  desirable  that  they  should  be 
as  early  in  the  year  as  possible,  in  consequence  of  the  pmcticeor 
running  horses  so  earlyas  two  end  three  years  old. 

A  few  months,  in  a  young  aninial,  often  makes  a  material  dif- 
ference in  its  size  and  strength;  and  as  thorough- bred  mam, 
at  this  time,  arc  kept  in  comfortable  boxes,  the  inclemency  of 
tlie  weather  is  of  little  con!ic(|i)cncc.  In  other  horses,  the  plan 
of  early  foaling  would  not  aiuwcr,  iu  consc<iucncc  oflhv  want  of 
sufficient  pasturage. 

Tlie  following  arc  the  changes  by  which  wc  judge  of  tlvc  age 
of  a  horse:  it  a  unncct-stary  to  notice  the  mohir  In-th,  as  ihry 
cannot  be  readily  cxaniincil,  nor  the  upper  inciH>rst  us  tlicir 
cliungrt  are  vciy  tiiiccrtaiii :  — 

At  biith,  the  uipiiers  only  have  made  their  appearance. 

At  oiie  year  old,  tlie  incisors  are  all  viuble,  the  comers  having 

appeared  last. 
[At  two  years  old,  ihe  nippers  have  lost  llidr  marks,  and  both 

edges  of  the  eornera  ure  level. 
[At  three  years  old,  and  several   montlis  before,  the  permaiieni 

nippers  have  made  their  appearance. 
'At    four  yoiiii  old,   the  permanent  dividers  appear,   and  tlie 

cavity  has  nearly  disappeared  in  the  temporary  corner*. 
At  five  years  old,  the  mouth  is  utid  to  be  pertect ;  and,  if  a  male^ 
the  tushes  ai-e  up ;  the  permanent  corner  teeth   have  ap- 

Iieurcd,  but  the  posterior  border  of  the  cavity  is  much 
ower  limn  the  anterior;  and  the  mark  is  much  dimininhed 
in  die  nippers. 

At  six  years  old,  the  mark  has  disappeared  from  the  nippers, 
and  considerably  diminished  in  the  dividers;  but  the  inner 
edge  of  the  corners  i^  not  yet  level. 

At  seven  years  old,  the  mark  has  disappeared  from  the  nipfien 
and  dividei-s,  and  the  corners  arc  level,  though  still  retain- 
ing the  mark. 

At  eight  years  old,  the  mark  has  disappeared  from  the  comen 
also,  and  the  horse  is  said  to  be  aged.     Tlie  face  of  the

remains  several  year*.     The  niarlcH  in  llie  upper  leetli  b? 

this  lime  have  disappetired;  Kome  uiy  at  eleven  years  old, 

but  this  is  very  iinceriaiii. 
tAt  fifteeji  years  old,  the  nippera  bave  become  triangular,  having 

l)een  f;riiduiiUy  assuming;  thU  shape  tor  the  jaxt  two  years. 

The  futtowiiif;  year  the  dividers  amume  this  shape,  and, 
kt  aeveiHeen  years  old,  the  lower  incisors  are  all  triangular,  and 

lUi-  eeniial  enamel  has  disappeared  from  tbe  up[)er  incisors. 

After  this,  the  face  of  the  teeth  lengthen  from  front  to  rear, 

and  diminish  from  side  to  Bide. 

In  judging  of  the  age  of  a  hoi-se,  wc  must  not  expect  the  fore- 
going rules  to  be  invariably  correct,  parficidarly  after  eight 
years,  but  tlicy  will  be  in  many  cases,  and  in  all  will  materially 
as«ist  the  judgment,  and  enable  us  to  make  tbe  iuiportaiu  dis- 
tinction between  one  hoi-se  of  len  and  anotlier  of  twenty  yi^rs. 

lere  are  some  horses  that  retain  tbeir  marks  several  yeai-*  after 
the  usual  time;  it  is  desirable,  therefore,  not  to  be  guided  en- 
tirely by  one  rule,  but  to  let  one  correct  or  regulate  another, 

As  the  horse  increases  in  age,  tbe  incisor  teclh  appear  longer, 
and  oi^ume  a  more  horizontal  position,  and  other  signs  of  age 
appear  manifested. — Ed.]

grouiKl  upon  which  the  horse  stands  for  examination  gives  a  de-

some  convenient  place,  where  he  may  he  ex«mii)etl  without  iii- 
terrupiion. 

'lite  first  atid  moat  iin[)orinnt  point  to  be  iniiuirec)  into  is  tha 
time  of  tlie  feet  and  timhK,  and  tv)ii-itier  tlie  tiorw  be  in  any 
(Ic^ri-e  liimt;  or  not.  And  tboii^ii  lie  appear  (K-rfectly  firm  and 
free  from  larni-iiess  in  ail  hi*  paoes,  il  will  be  neeefwiry  to  inspect 
carefully  llie  feet  and  limb:*,  lent  tliere  be  any  defect,  which  at 
some  future  period  may  nccasiori  lameness.  It  it  a  fact  pretty 
well  known  to  hor*e> dealer**,  that  a  slight  degree  of  Umeness  >s 
easily  concc«teil,  (wrticularly  in  liigh-spiriied  ImrM*',  bv  the 
BtimiiUi»  of  the  whip  mid  ipiir,  and  supj>oriin)^  ihe  head  with 
the  bridle.  To  ascertain,  therefore,  wlieilier  a  horse  Iw  lame  or 
not,  he  should  not  be  ridden,  but  a  person  ahould  be  made  to 
run  before  him,  holding  the  end  of  the  bridle,  that  the  head 
may  receive  no  supjmrt  from  it;  the  slightest  lameness  will  then 
be  readily  jierceived,  particularly  if  the  trial  be  made  on  roiigli 
ground,  and  on  a  moderate  declivity. 

Sliould  it  appear  that  the  horse  is  perfectly  free  from  lanie- 
neia,  the  feel  and  legs  are  to  be  carelully  inspected,  beginning 
with  the  former,  which  should  be  6rst  viewed  in  linonl,  as  the 
hone  stands,  to  observe  if  there  be  any  difference  in  the  fonn 
or  size  of  the  hoofs.  If  tlie  feet  are  very  small,  and  particularly 
if  one  foot  upiieant  lunalli-r  tiian  die  other,  it  affords  reasonable 
catiM  for  Hu<^picion  ihiii  there  is  some  serious  defi-ct ;  the  bottom 
of  the  foot  in  then  to  be  examined ;  and,  if  the  heels  arc  much 
contncted,  the  frog  im])erfect,  and  matter  issuing  from  its  cleft 
or  division,  it  ic  protiable  that  the  horse  will  soon  become  lame. 
1  would  not  adviM!  that  *  horse  be  rejected  merely  because  ilie 
feel  l»ave  become  rather  narrow  at  the  heels,  and  smaller  than 
llwy  were  originally.  If  no  difference  can  be  perceived  in  the 
size  of  the  feet,  if  die  frogs  appear  sound,  and  fret-  from 
thrushes,  and  particularly  if,  at  the  same  time,  the  horse  step 
boldly  and  firmly  wtien  trotted  on  rough  ground,  and  down  a 
hill,  1  think  he  may  be  safely  purchased,  if  free  from  all  oihcr 
tlefectsi.  The  next  point  to  be  attended  to  is  the  form  of  the 
M)le,  or  bottom  of  tlie  foot,  whicli  is,  in  its  natural  stale,  rather 
hollow,  or  o<»ncave;  we  sometimes,  however,  find  it  quite  Hat,  or 
even  convex :  in  either  case,  it  is  proportionally  thin,  and  unfit

Cutting  on  the  insidct  and  immediately  below  tlie  knee-joint, 
or  lite  ^>eedi/  cut,  &3  il  is  termed,  is  also  a  material  defect,  as 
it  sometimes  causes  a  horse  to  foil  suddenly  iti  trotting  or  gal-

swelling;  and  if  the  leg,  on  a  side  view,  Appear  flat,  clean,  and 
sinewy,  as  ic  is  termed ;  it  may  be  considered  as  a  sound,  well- 
formed  leg.  Bnt  if  the  leg,  on  aside  view,  appear  rather  round 
than  flat,  or  rather  bent  and  inclining  inwanis;  if  the  sinew 
and  ligament  cannot  be  distinctly  and  separately  felt ;  and  par- 
ticularly if  one  leg  IS  larger  than  the  other;  it  may  be  con- 
cluded, that  the  part  has  sustained  some  injury,  and  that  ihefe 
ia  a  probability  of  the  horse  becoming  lame,  when  put  to  hard 
work. 

If  any  mark  he  found  on  the  knees,  it  is  the  safest  olan  to  in-* 
fer  that  it  was  occasioned  by  falling,  though  the  seller  should 
affirm  iliat  it  happened  in  going  over  the  bar,  stepping  into  a 
boat,  or  by  strikuig  it  against  (he  manger. 

I'ew  horses  are  entirely  free  from  splents;  they  need  not,

tliDuld  proceed  to  Ok  eye,  which  is  an  important  part,  and  re* 
quiree  the  motit  card'ul  in*]>ection.  The  most  favounible  »iliu* 
tion  for  viewing  tlu-  eye  is  at  the  stable  door,  or  under  a  nlK^d; 
for  whcu  too  nuich  llj^ht  falls  upon  the  eye,  so  much  i*  refh-cted 
by  iu  eoriica,  or  nur&ce,  that  it  is  difficult  to  see  liie  itucnul 
part*. 

The  1^  al  wliicli  the  eyes  most  frequently  become  disoiurd  ii 
from  five  to  «ix ;  next  to  inM,  from  four  to  five ;  soinetinHt,  biii

i»tving  taken  a  geiHT«l  view  of  the  eye,  the  pu])il,  or  darii

or  if  white  specks  are  so'u  in  them,  a  dixciiM-d  state  of  the  organ

causing  any  material  impediment  to  vision.  1  should  noi, 
therefore,  reject  a  horse  simply  on  account  of  thb  delVxt ;  that

able,  however,  to  be  certain  that  the  pupils  are  alike  in  size, 
that  they  become  small  when  the  eyes  are  exposed  to  a  strong 
light,  and  enlarge  again  when  the  horse  is  brought  into  a  darker 
situation. 

When  an  imperfection  is  observed  in  the  eye,  it  is  frequently 
said  to  arise  from  a  bite,  or  blow,  or  from  hay  seeds  falling  into 
it;  but  though  the  seller  should  positively  affirm  this  to  be  the 
cause  of  the  imperfection,  I  should  always  be  inclined  to  doubt 
it,  because  experience  has  taught  me  that  the  diseases  of  the 
horse's  eye  almost  always  arise  from  internal  causes ;  that,  how- 
ever trifling  in  appearance,  they  are  really  of  a  serious  nature, 
and  most  commonly,  even  after  they  have  been  apparently  cured, 
terminate,  sooner  or  later,  in  blindness.  Too  much  caution, 
therefore,  cannot  be  observed  in  examining  this  important 
parL 

When  the  eyes  become  inflamed  from  a  blow  or  bite,  or  from 
any  dust  getting  into  them,  the  disease,  although  apparently  con- 
siderable, is  seldom  of  long  continuance;  that  is,  when  the  injury 
is  not  severe,  and  proper  means  are  employed  for  its  removal. 
But  when  the  inflammation  has  subsided,  there  often  remains  on 
the  surface  of  the  eye  an  opaque  spot,  or  film^  as  it  is  termed, 
which  in  severe  injuries  extends  over  the  whole  of  the  cornea, 
or  surface  of  the  eye.  After  a  little  time,  this  opacity  gradually 
diminishes,  and  sometimes  wholly  disappears ;  more  commonly, 
however,  a  small  film  remains,  which  does  not  in  any  material 
degree  impede  vision ;  this  defect,  therefore,  is  of  no  importance, 
and  may  safely  be  overlooked,  provided  the  purchaser  is  certain 
that  the  opacity  is  really  on  the  surface,  and  not  in  the  pupil  of 
the  eye,  and  that  the  other  parts  appear  bright,  and  free  from 
every  kind  of  imperfection.  As  a  further  security,  a  condition 
may  be  annexed  to  the  warrant}',  by  which  the  horse  may  be  re- 
turned in  three  or  four  months,  should  the  imperfection  prove 
to  be  of  a  serious  nature.  When  a  complete  cataract  takes 
place,  which  is  known  by  the  pupil  being  of  a  white  or  pearl 
colour,  the  strength  of  the  other  eye  b  generally  restored,  and 
it  rarely  becomes  diseased  afterwards,  except  from  accidents :  he 
may,  therefore,  be  safely  purchased  as  a  one-eyed  horse. 

We  have  now  to  extend  our  investigation  to  another  point; 
that  is,  the  state  of  the  wind,  or,  rather,  of  the   lungs,  and 

Earts  connected  with  them.  When  a  horse  is  absolutely 
roken- winded,  there  is  no  difficulty  in  detecting  the  disease: 
the  laborious  breathing,  or  working  of  the  flanks,  particularly 
in  going  up  a  hill,  and  the  short  asthmatic  cough,  are  symptoms 
which  cannot  escape  observation.  Between  this  state  of  the 
lungs  and  perfect  health  there  are  many  degrees,  and  it  is  the 
intermediate  defects  that  we  find  most  difficulty  in  discovering. 
The  criterion  by  which  dealers  judge  of  the  state  of  the  wind,  ia

ihow  who  have  often  occasion  to  purchase  horses,  to  make  thcin-

winded  cough:  there  will  be  no  difficulty  in  this,  as  the  CM^

importance,   and  with   care   easily  removed ;   it   often    provoi 
however,  extremely  obstinate,  and  not  unfi'equently  incurabin 
When   a   horse   is  observed  to  hare  a  cough  at  tho  time  of 
jjurchasing,   it  is  necessary  to  inquire  whetlter  it  be  a  recent 
uomplaini  or   one  of  long  standing;  and  this  ti  a  point  thsi 
cannot  be  always  easily  determined.     In   the  old,   or  chronic 
cough,  as  it  is  termed,  ibe  hor^;  generally  appears  lively,  fc«di 
Iwariily,  and  apjiears  in  every  other  respect  to  Ik-  in   perfrct 
health ;  Rometimeii  llie  sound  of  the  cough  is  husky,  or  asthmatic^ 
which  indicates  a  tendency  lo  broken  wind ;  more  commonly  it 
is  loud  an<l  clear ;  tlie  fit  of  coughing  is  gcnerully  violent,  and 
the  horse  ufteii  appears  as  if  some  eximneoit*  body  Itad  got  inU 
the  windpipi',  and  he  was  endeavouring  to  cough  it  up. 

The  chronic  cougli  is  most  considerable  whi:n  tt>e  horse  it 
first  put  in   motion ;  by  continuing   tlie  exercise  it  graduailj 
ccascii,  after  which  the  horse  may  be  rode  a  long  journey  without 
coughing.     1    have   often   oliservMl   that   Itonc*   with    chronic 
cnngh  are  very  shy  of  having  their  throats  iuuc)H<d,  often  rest- 
ing .-mil  making  cansidemble  resistance  when  any  nnc  Bltem||flH

in  many  instances  I  have  oliserve<l  iluii  they  cannot  be  made  lo

tl)i»,  probably,  as  well  as  the  sliynets  they  manili'st  on  the  occasion, 
may  arise  rruni  the  trini  having  born  made  often  upon  lliem. 

In  the  recent  cough,  the  horse  generally  appears  ratlier  dtilli 
and  looks  like  a  hor»e  lubouring  under  a  catarrh,  or  cold  :  be 
readilv  coughs  when  the  wii)dpi|>c  is  pinched  ;  in  doing  which 
there  is  no  difficulty,  as  the  horse  seldom  makes  any  considerable 
nesJataiiee.     In  the  recent  cough,  moderate  trotting  is  sufficicel 


BINTS   TO    THE    PURCHASERS    OF    HORSES.  887 

to  excite  coughing,  which  is  seldom  diminished  by  continuing 
the  exercise.  In  tlic  chronic  coucti,  the  horse  is  sometimes  re- 
lieved by  throwing  up  mucus  through  the  nostrils;  and  the 
cough  is  often  so  moderated,  by  strict  attention  to  his  diet  and 
exercise,  as  to  appear  scarcely  worth  notice.  I  have  also  known 
it  completely  suppressed  for  the  space  of  a  day,  by  means  of 
opium.  When  a  horse,  therefore,  is  observed  to  have  a  cough 
the  purchaser  may  not  always  be  able  to  determine  whether  the 
complaint  be  unimportant,  or  of  long  standing,  and  incurable. 
In  such  doubtful  cases,  it  would  perhaps  be  the  most  prudent 
plan  to  secure  himself  by  having  a  suitable  condition  added  to 
the  warranty. 

There  b  another  complaint  of  the  lungs,  or  parts  connected 
with  them,  and  an  incurable  one,  which  the  purchaser  should  be 
guarded  against  This  disease  is  named  roariiy,  from  the 
wheezing  noise  a  horse  makes  when  rode  fast,  particularly  when 
galloped  up  a  hill :  it  is  sometimes  so  considerable  as  to  be  heard 
at  a  distance  of  many  yards ;  but  in  walking,  or  moderate  exer- 
cise, it  can  seldom  be  perceived.  The  method  which  dealers 
usually  employ  to  detect  this  complaint,  at  a  repository,  where  no 
other  trial  is  allowed,  b  to  whip  the  horse  under  the  belly,  and 
make  him  turn  suddenly,  or  by  making  him  leap  over  the  bar; 
if  be  b  a  roarer,  thb  sudden  exertion  causes  him  to  grunt.  But 
tfab  criterion  should  never  be  depended  upon  when  an  opportu- 
nicy  oflers  of  galloping  the  horse. 

The  age  of  a  horse  is  known  by  certain  marks  in  the  teeth, 
as  described  in  the  preceding  chapter.  When  these  are  worn 
out,  artificial  marks  are  sometimes  made,  to  make  the  horse  ap- 
pear younger  than  he  really  is.  It  often  happens,  also,  that  some 
of  the  sucking,  or  colt's  teeth,  ate  drawn  out ;  in  which  case  they 
are  soon  replaced  by  horse's,  or  permanent  teeth ;  this  is  done 
with  a  view  to  make  a  horse  of  three  or  four  years  old  appear 
to  be  five.  As  experience  alone  can  enable  the  purchaser  to 
detect  these  deceptions,  it  is  advisable  to  have  the  age  of  the 
horse  always  expressed  on  the  warranty ;  he  can  then  avail  him- 
self of  the  first  opportunity  that  offers  of  obtaining  correct 
information  on  the  subject,  and  if  he  has  been  deceived,  wUI, 
no  doubt,  have  a  right  to  return  the  animal. 

I  have  known  persons  so  cautious  when  about  to  purchase  a 
horse,  as  to  examine  the  neck,  and  if  they  find  marks  of  his 
having  been  bled  often,  they  suspect,  sometimes  justly  perhaps, 
that  he  has  had  some  serious  complaint  They  have  also  thought 
it  necessary  to  inspect  the  chest,  belly,  thighs,  or  the  parts 
ii4iere  rowels  are  usually  placed,  and  if  they  observe  the  marks 
which  generally  remain  after  rowelling,  they  suspect  it  was  done 
for  a  complaint  of  the  eyes  when  the  mark  is  under  the  throat, 
or  between  the  branches  of  the  under  jawbone ;  and  if  in  other

HINTS   TO   THE    PURCHASERS    OF    HORSES.  389 

Perhaps  I  have  dwelt  longer  upon  this  subject  than  some  of 
my  readers  may  think  necessary ;  but  it  should  be  recollected 
that  it  is  intended  only  for  those  that  are  inexperienced  in 
horses.  It  may  be  thought,  also,  that  what  I  have  written  may 
tend  to  excite  an  unjust  prejudice  in  the  minds  of  those  to  whom 
it  is  addressed,  or  that  it  may  make  them  over- cautious,  and 
induce  them  to  reject  horses  without  sufficient  reason :  but,  if 
we  take  into  consideration  the  many  defects  or  diseases  to  which 
horses  are  liable,  the  difBculty  of  detecting  them,  the  numerous 
deceptions  that  are  practised,  and  the  shifts  and  evasions  some- 
times resorted  to,  I  trust  that  in  what  I  have  written  the  candid 
reader  will  not  accuse  me  of  having  gone  too  far,  or  that  it  will 
excite  an  undue  prejudice  against  the  horse-dealer.  I  am  aware 
that  there  are  men  in  that  trade  who  would  descend  to  the 
deceptive  practices  I  have  occasionally  hinted  at,  but  have  no 
doubt  that  there  are  also  to  be  found  among  them  men  of  in- 
t^rity  and  honour. 

I  cannot  conclude  this  subject  without  advising  those  who  are 
satisfied  witli  a  moderate  degree  of  goodness  !n  a  horse  to  put 
up  with  a  few  trifling  faults,  as  it  often  happens  that  the  rider 
is  as  much  in  fault  as  the  horse;  and  after  a  little  use  these 
trivial  faults  often  disappear. 

[There  is  no  money  better  expended,  when  purchasing  a 
valuable  horse,  than  the  payment  of  the  ten-shilling  fee  to  a 
TeapecUd>U  veterinary  surgeon,  one  whose  professimal  know- 
ledge enables  him  to  form,  and  whose  repulaiion  induces  him  to 
give,  a  correct  and  honest  opinion  as  to  the  soundness  of  a 
horse.  Through  saving  this  trifling  sum  hundreds  of  pounds 
have  often  been  subsequently  lost.  The  certificate  of  a  veterinary 
surgeon  as  to  the  soundness  of  a  horse  does  not  prevent  such 
horse  from  being  returned  should  he  afterwards  manifest  such 
symptoms  as  would  prove  him  to  be  unsound  at  the  time  of 
sale.  Cases  may  occur  in  which  disease  may  exist  in  a  latent 
form,  and  which  professional  vigilance  may  be  unable  to  detect. 
But  to  one  case  of  this  sort  tnere  are  hundreds  in  which  the 
unsoundness  would  have  been  detected  by  the  veterinary  sur- 
geon, though  not  by  the  owner  or  amateur.  There  are  two 
grounds  on  which  a  horse  can  be  returned,  and  the  value  re- 
covered. One  a  breacli  of  warranty,  the  other  on  proving  a 
fraud.  If  a  horse  be  warranted  sound,  free  from  vice,  steady 
in  harness,  and  five  years  old,  and  he  proves  either  unsound, 
vicious,  unsteady  in  harness,  or  more  or  less  than  five  years,  the 
warranty  is  broken,  and  the  horse  is  returnable.  The  war- 
ranty must  either  be  written  or  be  given  before  a  witness,  and 
must  be  at  or  after  the  time  of  sale,  not  before  iu  It  is  of  little 
use  the  dealer  saying  that  he  will  warrant  the  horse  unless  he 
actually  does,  and  any  professioiH  that  he  may  make  &T&tiMn\.  \»

not  the  cave  at  presenL 

The  other  ground  on  which  a  horse  can  be  returned,  tliat  of 
fraiid,  is  more  difficult  to  pnive.  If  a  person  sells  to  another  u 
ehnidered  Iioi'j«  at  >uc)i  a  price  as  the  animal  would  be  wortli

ainoum  us  wril  as  tlutt  of  the  damage,  should  the  infection  harr 
been  eommuniented  to  otlter  lior«o»  beloiijniig  to  him.  If  any 
gross  deceplidti  be  pmciised  to  hide  a  wilt  llie  horse  it  re- 
lurriahle  on  the  ground  of  fraud,  though  no  warranty  be  given. 
It  is  neceuary,  liowev<'r,  that  the  fault  nfterwiirds  disooverel

that  makes  him  in  any  respect  less  useful,  or  is  likely  to  make 
him  less  useful  than  he  would  be  without  such  defect.  Soundness 
has,  therefore,  strict  reference  to  utility ;  it  does  not  apply  to 
blemishes,  although  they  may  be  alterations  of  structure  and 
produced  by  disease.  Freedom  from  blemishes  must  be  specified 
in  the  warranty,  in  order  to  guard  against  them.  With  regard 
to  the  greater  number  of  points,  veterinary  surgeons  are  pretty 
welt  agreed  as  to  what  is  unsoundness  and  what  is  not ;  but  there 
are  some  cases  in  which  there  is  a  difference  of  opinion :  some 
practitioners,  perh^,  are  too  strict  in  their  opinion,  and  others 
not  strict  enough,  but  there  are  many,  it  is  to  be  hoped,  who 
preserre  the  happy  medium. 

On  the  following  diseases,  no  doubt  can  be  entertained  that 
they  constitute  unsoundness :  — 

Lameness  of  all  kinds  and  degrees ; 

Diseases  of  any  of  the  internal  viscera ; 

Cough  of  all  kinds,  as  hng  as  it  exists ; 

Colds  or  catarrhs,  while  they  last ; 

Roaring  * ;  broken  wind ;  thick  wind ; 

Grease;  mange;  farcy  and  glanders ; 

Ruptures  or  hernia  of  all  kinds ; 

M^rims,  if  manifested  both  before  and  after  the  time  of  sale; 

Founder,  and  convex  feet ;  also  contracted  feet,  unless  natu- 
rally so; 

Ravins  and  ringbones ; 

FTnlargements  of  the  sinews  or  ligaments; 

Cataracts  and  other  alterations  of  structure  in  the  eyes  that 
impede  or  are  likely  to  impede  vision. 

Crib-biting  is  now  considered  unsoundness,  as,  though  at  first 
but  a  vicious  habit,  its  ultimate  effect  is  to  injure  both  strength 
and  condition. 

The  following  diseases  either  may  or  may  not  occasion  nn- 
Boundness,   according  to  the   state   or  degree   in   which   they 

■  Some  horses  make  a  considerable  noise  either  on  first  going  oS*  or  on 
being  mucb  excited,  but  which  frequently  goes  off  after  awhile,  and  maj  be 
diattn^uished  from  roaring  \>y_  the  Utter  increasing  with  speed  and  the  former 
diminishing.  It  evidently  arises  from  soiiie  peculiar  action  of  the  nostrils, 
which  may  be  seen  to  be  greatly  inflated,  and  thus  produce  a  sort  of  Ttbrstion. 
It  is  said  that  Eclipse,  the  celebrated  race-horse,  was  a  roarer  ;  ifso  he  must 
iwTe  be«n  one  of  this  sort,  I  have  known  many  Bupcrior  hunters  make  this 
peculiar  noiac.  It  docs  not  impede  usefulness,  and,  therefore,  although  it 
may  be  disagreeable,  doea  not  constitute  unsoundness  ;  for  Lord  Ellenborough 
has  decided  that "  if  the  horse  emits  a  loud  noise  which  is  ofTensive  to  the  ear 
merely,  from  a  had  habit  which  he  has  contracted,  or  trom  any  cause  which 
does  not  interfere  witli  his  general  hculth  and  muscular  [)awers,  he  is  still  to 
be  considered  a  sound  horse :  on  the  other  hand,  if  the  roaring  proceeds  froni 
any  disease  or  organic  infirmity,  which  renders  him  incapable  of  performing 
the  usual  functions  of  a  hone,  then  it  docs  constitute  unsouodness."  —

classes  of  mediciaes,  especially  to  diuretics,  alteratives,  cordials* 
and  tonics.  The  sanction  of  such  authorities  is  sufficient,  it  is 
hoped,  to  obviate  any  objections  that  may  be  made  to  the  com- 
plexity of  some  of  the  formulie :  and  though  the  structure  of  the 
human  stomach  and  parts  connected  with  it  is  so  dif^rcnt  from 
those  of  the  hone,  as  to  render  all  analogical  reasoning  as  to  the 
effect  of  medicine  uncertain,  yet  we  have  been  too  precipitate, 
perhaps,  in  dismissing  it  almost  entirely  from  our  consideration. 
There  are  several  medicines,  such  as  sugar  of  lead,  white  vitriol, 
&c^  which  produce  scarcely  any  effect  on  the  horse,  though  of 
considerable  power  in  the  human  body;  yet  it  is  not  very  impro- 
bable that  such  medicines  when  given  daily  for  some  time  in 
small  doses  may  produce  a  salutary  effect,  or  even  prove  delete- 
rious when  largely  and  incautiously  so  employed.  Arsenic  has 
been  given  to  a  horse  in  a  dose  of  two  drachms  twice  a  day,  for 
several  days,  without  any  considerable  effect  being  produced ; 
bat  in  one  case  a  sixth  part  of  that  quantity  occasioned  a  fatal 
inflammation  of  the  stomach  and  bowels.  When  the  stomach  of 
a  horse  is  in  a  healthy  state,  it  will  bear  an  astonishing  quantity 
of  medicines  which  in  the  human  stomach  are  either  poisonous 
or  powerful  medicinal  agents ;  but  in  some  diseased  states  of  the 
horse's  stomach,  which  are  not  unfrequent,  the  same  medicines, 
or  others  commonly  deemed  innocent,  will  produce  a  powerful 
and  even  fetal  effecL  Mr.  James  Clark  relates  two  cases  of  this 
kind:— one  of  the  horses  died  from  taking  a  pint  of  vinegar, 
and  the  other  from  taking  a  drench  in  which  there  was  one 
ounce  of  nitre  and  half  an  ounce  of  spirit  of  hartshorn.  The 
experiments  that  have  been  made  with  a  view  to  ascertain  the 
effect  of  medicine  upon  the  horse  should  not  be  too  confidently 
depended  upon,  as  Uiey  have  generally  been  made  on  glandered 
bones,  or  such  as  were  incurably  lame;  in  which  case  it  may 
lairly  be  presumed  that  the  stomach  was  in  a  healthy  state.  The 
experiments  that  have  been  tried  also  to  ascertain  the  effect  of 
tobacco  on  the  horse  afford  a  striking  proof  of  the  propriety  of 
attending  to  this  circumstance.  At  the  Veterinary  Collie  an 
immense  dose  (it  has  been  stated  three  pounds,  in  infusionj  has 
been  given  without  any  perceptible  effect;  at  Exeter  a  much 
smaller  quantity,  not  exceeding,  I  believe,  two  or  three  ounces, 
was  infused  in  a  quart  of  beer  during  the  night,  and  in  the 
morning  given  to  a  horse  at  one  dose ;  immediately  after  taking 
it  the  animal  fell  down  and  died. 

From  considerations  of  this  kind,  the  Author  has  been  led  to 
believe,  that  simplicity  of  prescription  in  veterinary  as  well  as 
human  medicine,  may  be  carried  too  far;  and  that  many  useful 
medicines,  and  combinations  of  medicines,  or  receipts,  may  be 
improperly  dismissed  from  the  Veterinary  Materia  Medica  and 
Pharmacopoeia,  were  we  to  confide  too  much  in  the  experiments

that  have  been  made  on  the  healthy  stomach,  or  attempt  to  form 
general  rules  or  deductions  from  one,  two,  or  three  experiments, 
liowever  carefully  they  may  have  been  conducted.  TTiere  is  only 
one  source  from  which  any  precise  or  really  useful  knowledge  a 
this  interesting  subject  can  be  derived;  that  is,  a  car^iil andin^ 
partial  observation,  and  an  accurate  recollection  o^  the  tymptam*  t^ 
diseases,  and  the  effects  of  such  medicines,  whether  simple  or  com- 
pound,  as  are  employed  for  their  removal. 

With  respect  to  the  names  of  the  simple  and  compound  medi- 
cines, the  Author  has  for  the  most  part  employed  those  of  the 
last  London  Dispensatory,  by  Thomson,  1830;  but  he  hu 
given  also  the  older  and  more  common  names,  and  in  such  t 
manner  as  may  make  the  general  reader,  or  the  young  Veteri- 
narian, ^miliar  with  both  :  for  our  medical  nomenclature,  even 
when  founded  on  chemistry  or  botany,  will  probably  be  variable 
and  uncertain. 

[The  additions  made  by  the  Editor  of  the  present  edition  are 
by  no  means  numerous.  They  consist  principally  of  some  aew 
medicines,  whose  effects  have  been  ascertained  to  be  useful  or 
valuable  in  the  horse.  In  supplying  this,  he  has  had  free  re- 
course to  the  Veterinary  Pharmacopceia,  lately  published  t^ 
Mr.  Morton,  Lecturer  on  Chemistry  at  the  Veterinary  CoU^e,  to 
whose  valuable  work  he  begs  to  refer  for  a  more  scientific  acquaint- 
aftce  with  the  greater  portion  of  medicines  used  for  animals. 

In  former  Editions,  the  names  and  properties  of  a  number  of 
medicines  were  given  which  had  cither  never  been  tried,  or  had 
been  found  useless  for  the  horse ;  these  have  been  freely  erased, 
as  their  i-etentioii  could  have  answered  no  useful  end.  There 
are  some  medicines,  however,  whose  use  and  value  for  animsls 
have  been  disputed,  being  praised  by  some  and  condemned  by 
others ;  these  have  been  retained  in  order  to  afford  every  facility 
to  those  who  fvould  again  try  their  effects :  the  convenience  of 
parties  in  situations  where  particular  medicines  cannot  be  ol^ 
tained  has  also  been  considered  in  the  present  Edition.  The 
Editor,  in  condensing  this  portion  of  the  work,  has  endeavoured 
to  render  it  more  valuable.  —  En.j 


WEIGHTS   AKD   MEASURES. 


The  measures  employed  in  medicine  are  of  two  kinds,  one  for 
solids,  the  other  for  liquids.  But  there  are  some  fluids  much 
heavier  than  water,  such  as  sulphuric  acid  and  Goulard's  Ex- 
tract; and  there  are  others  much  lighter,  such  as  ether  and 
alcohol  or  spirit  oE  wine-,  sucVv  Vit^wvis  ate,  therefore,  sold  by

weiffht.  Formerly  a  drop  was  the  smallest  liquid  measure ;  tliis 
being  found  very  variable,  depending  upon  the  size  and  form  of 
the  vessel  from  which  tlie  liquid  was  dropped,  upon  the  density 
of  the  liquid,  and  other  circumstances,  a  more  correct  and  con- 
venient method  has  been  estabiishcd.  For  tills  purpose  a  small 
glass  measure  is  made,  in  which  the  drachm,  or  sixty  grains,  is 
divided  into  sixty  parts,  which  arc  named  minims;  it  is  therefore 
named  a  minim  glass,  and  the  term  minim  is  substituted  in  pre- 
scriptions or  receipts  for  drops.

In  reading'  French  medical  or  veterinary  books,  some  difficulty 
is  experienced  in  bringing  their  measures  to  correspond  with 
ours,  in  consequence  of  dicir  having  adopted  a  decimal  division, 
both  in  their  liquid  and  dry  measure,  and  they  also  appear  to 
feel  a  similar  inconvenience  from  the  difference  between  liie  old 
and  the  new  division  of  measure.  For  example:  in  Thomson's 
London  Dispensatory,  the  French  gramme  is  stated  to  be  equal 
to  15*444  grains,  or  about  15  grains  and  a  half.  Dr.  Nysten,  in 
his  Dietionnaire  Medicate,  makes  the  gramme  amount  to  20 
grains;  and  in  Bourgelat's  Matiere  Medicale,  by  Huzard,  it  is 
stated  to  be  equal  to  16  grains.    Tlierc  appear  to  be  some  errors

'Diere  is  an  obvious  error  in  this  table;  for  if  one  gramme  ii 
equal  to  one  scruple,  four  grammes  must  exceed  one  drachm.  I( 
therefore,  four  grammes  are  equal  to  one  drachm,  one  gramme  can 
only  be  equivalent  to  fifleen  groins,  instead  of  a  scruple  or  twmtj

In  Nysten's  last  table,  1  centilitre  is  said  to  be  equal  lo  10 
grammes,  or  half  a  drachm.  This  is  a  considerable  error  j  for  if 
the  gramme  be  taken  only  at  15  grains,  10  grammes  would  amount 
to  150  grains,  or  2^  drachms.

ABLUENTS  (from  ad/uo,  to  wash  away).  Medicinal  liquids, 
or  water  slightly  impregnated  with  mucilage,  such  as  bran  tea, 
or  white  water,  linseed  tea,  or  decoction  of  manh mallows,  wliich 
are  supposed  to  wash  away  or  carry  off  gradually  any  noxious 
matter  there  may  be  in  the  stomach  or  bowels,  the  biliary  or 
urinary  passages,  or  the  blood. 

ABSORBENTS.  Medicines  that  absorb  or  neutralise  any 
acid  matter  there  may  be  in  the  stomach  or  bowels.  Of  this 
kind  are  potash,  soda,  magnesia,  chalk,  common  clay  and  earth; 
the  two  last  owe  their  absorbent  properties  to  the  carbonate  of 
lime  they  contain.  The  formation  of  acid  in  the  stomach  de- 
pends on  some  derangement  of  that  important  organ,  which  is 
brought  on  by  the  improper  quantity  or  quality  of  the  animal's 
ibod.  It  will  be  to  little  purpose,  therefore,  to  give  medicine  to 
absorb  the  acid,  unless  the  state  of  the  stomach  be  corrected, 
which  cannot  be  done  without  avoiding  the  cause  which  dis- 
ordered it.  Thb  morbid  state  of  the  stomach,  and  consequent 
formation  of  an  acid  in  it,  is  very  common  among  horses,  and  is 
indicated  by  a  disposition  to  eat  earth  or  drink  muddy  water, 
especially  when  it  is  rendered  turbid  by  clay  or  chalk ;  and  for 
want  of  these  they  will  gnaw  or  lick  the  walls  of  the  stable,  or 
the  dirt  from  their  stalls,  or  eat  their  litter.  This  state  of  the 
stomach  appears  to  be  brought  on  by  eating  too  much  hay, 
especially  when  the  hay  is  indifferent  or  bad ;  and  this  propen- 
li^  to  eat  too  much  hay  is  acquired  gradually,  by  keeping  young 
horses  idle  in  the  stable  with  a  rack  full  of  hay  before  them,  and 
allowing  them  too  much  water;  also  by  irregular  feeding,  that 
ii^  keeping  them  tasting  too  long,  and  then  giving  them  as  much 
as  they  choose  to  eat  and  drink;  or  by  giving  them  bad  hay,  and 
an  insufficient  quantity  of  oats,  or  baa  oats  as  well  as  bad  hay; 
exposing  the  animal  to  cold  and  wet,  when  heated  and  fatigued 
by  exercise,  will  disorder  the  stomach,  and  immoderate  work 
will  do  the  same.  In  whatever  manner  this  morbid  condition  of 
tbe  stomach  is  brought  on,  it  must  be  obvious,  aflcr  what  has 
been  said,  that  absorbent  medicines  can  only  act  as  palliatives, 
and  as  such  they  are  certainly  useful.  It  is  advisable,  however, 
to  give  in  the  first  place  a  mild  dose  of  physic.  If  good  hay 
cannot  be  procured,  some  good  straw  may  be  substituted  for  it, 
and  a  mash  of  fresh  sweet  bran,  or  pollard,  by  some  named

or  some  barlcj-  that  has  been  boiled  or  stcvpcd  for  twenty  or  ihiny 
hours  in  water  may  be  given.  'Hie  farinaceous  or  saocfaariM 
root*,  such  as  potatoes,  parsnips,  mangel-wurzel,  or  carrots,  m^ 
be  found  useful,  especially  if  cooked  by  steam.  Tliough  an  im- 
provement in  diet  is  the  rcmi-dy  to  be  mainly  relied  upon  for 
reslurtng  the  stomach  to  health,  there  arc  otlier  circumstanw> 
to  be  atlrnded  (o,  which  may  hasten  or  aisist  in  the  cure.  Vun 
air,  regular  exercise,  assiduity  and  kindnns  in  the  groom,  sml 
llie  society  of  other  ltor»es,  viill  greatly  cxhilamie  the  nnimaJ'i 
spirits.  Slid  thereby  improve  the  digestire  finiction.  WIten  iht 
season  is  favourable,  a  run  at  grass  in  short  sweet  pasture  it 
perhaps  ttic  most  eHVcliuil  reiixily  of  all. 

Though  animals  are  led  by  instinct  to  eat  dirt  and  drink 
muddy  water,  in  order  lo  allay  the  iiritalion  caused  by  an  BOid 
in  the  stomach,  much  mischief  has  sometimes  nrisen  fromallowiff 
horse*  lo  indulge  such  an  appetite.  Mr.  Fcron  ■Intes  that  dmbv

ACACIA  CATECHU,  commonly,  but  improperly,  called 
Terra  Jsponica,  or  Japan  Earth,  and  Catechu,  or  more  properly 
Extract  of  Catechu,  ia  obtained  from  the  inner  dark-coloured 
wood  of  an  Acacia  tree,  which  grows  plentifully  in  the  mountains 
of  Kankaiia,  in  Ilindostaii,  and  flowers  in  June.  The  wood  is 
bolted  in  water,  and  when  .itrained  off  and  twiled  down  to  one- 
thitd  part,  is  set  in  a  place  lo  cool  for  one  day,  and  afcerwar<ls

rtrund  masses,  of  a  deep  chocolate  colour  internally,  with  the

and  for  protracted  diarrliipa  and  diabetes  in  doses  from  half  a

but  I  consider  all  ilie  preparations  of  lead  not  only  uniieceHwiry, 
but  dangerous  as  internal  lemedies,  though  one  very  large  close

ACIDIFICATION.  A  natural  or  artificial  operation,  by 
which  an  acidiRablc  substance,  becoming  saluraled  with  oxygi-n, 
acquires  the  property  of  an  acitl.  The  acidifiwi  substance  is 
called  the  batf,  and  its  nan>e  designnteit  the  particular  acid  of 
which  it  forms  a  part.  Thus,  the  haae  of  sulphuric  or  carbonic 
acid  is  sulphur  and  carbon. 

ACIDS.  All  substances  whether  solid  or  liquid,  which  have 
a  sour  taste,  are  termed  acids,  although  it  by  no  means  follows 
tliat  all  acids  arc  sour;  prtissic  acid,  for  instance,  is  not  so. 
Most  acids  are  composed  of  oxygen,  in  combination  with  n  com- 
bustible base,  and  when  several  itcids  lutvc  the  Mime  base,  united 
wtlh  different  proportions  of  oxygen,  the  name  of  that  which 
contains  the  larger  portion  terminates  in  ir,  while  (hat  of  the 
one  combined  with  the  smaller  quantity  ends  tn  ous;  thus  nitric, 
nitrous;  phosphoric,  phosphorous;  sululuiric,  sulphurous;  &c. 
Acids  possess  (he  property  of  changing  the  blue  juices  of 
vegetables  into  red,  and  of  readily  combining  with  alkalies, 
earths,  and  metallic  oxides,  forming  with  ihcm  various  kinds  of 
salts,  which  are  used  in  medicine.  Of  this  kind  are  the  pre- 
parations commonly  named  Glauber's  salt,  Epsom  salt,  blue  and 
white  vitriol,  sugar  of  lead,  Jkc. :  each  of  these  will  be  noticed 
under  its  re3]>ective  name.  Acids  arc  divided  into  three  clasaesi; 
viz,  mineral,  vegetable,  and  animal  acids.  The  mineral  acids 
used  in  veterinary  practice  are  the  sulphuric,  (he  nitric,  and  the

ACOKL'S  CALAMUS.  Sweet  Flag.  This  is  found  in 
most  parts  of  Europe,  growing  in  nmrsliea  or  sirmins  of  water. 
It  Hower^  in  May  and  June,  and  is  an  exi-diunt  stomachic.  Its 
doie  in  powder  i»  from  one  to  iwo  ounces,  misetl  with  hrun  or 
honey;  in  Infunion  from  four  to  six  ounces  may  be  given  with 
two  quant  of  wau-r. 

ADKI'S.  Hog's  Lurd.  Lard  it  emollient,  and  is  chiefly 
used  in  the  compo»iiionof  ointtnents.  If  longex{>oscd  loa  warm 
air  it  atlracls  oxygen  from  the  atniMphcre,  for  which  it  has  a 
strong  ufEnity,  and  become*  rancid. 

AlK.  As  the  iH-alth  of  horses  materially  depends  upon  the 
salubrity  of  the  air  in  which  they  are  kLi)t,  it  U  probable  that 
many  of  their  diseases  arises  from  the  little  attention  tliai  is  pnid 
to  the  ventilation  of  stables.  It  has  been  said  that  even  tlio 
fflandert,  a  fatal  and  contagious  disease,  haa  been  generated  by 
confining  horses  in  an  impure  air.  It  is  a  common  practice  with 
grooms,  particularly  those  who  fancy  themselves  profoundly 
skilled  in  tlie  art  of  farriery,  to  atop  every  crevice  tliev  can  find 
in  tl»e  stable,  so  that  pure  air  is  with  dilBciiUy  admiited;  and  tlie 
noxious  vapours  arising  from  tlte  litter,  from  perspirstlon  and 
respiration,  are  in  a  great  measure  confined.  Horses  thus 
situated  must  necessarily  suffer  in  a  greater  or  less  degree;  and 
though  the  air  may  not  lie  so  contaminated  as  to  occasion  fatal 
disease*,  it  is  tufficienlly  so  to  debilitate  tlie  constitution,  and 
l(»ereby  lay  a  foundniion  for  numerous  complaints,  as  well  as  to 
create  local  diseases,  such  as  indamed  eyes,  obstinate  coughs, 
and  pcrliaps  moon  hluuinets,  as  it  ia  termed.  Morses  that  liave 
weak  eye«  atid  lungi  are  sure  to  be  injured  by  this  treatment. 
Anotlicr  inconvenience  arising  from  it  is  that  of  rendering  a  horse 
very  KUtceptibli-  of  cold.  I'mlitalion  is,  tlierelbre,  an  object  of 
great  imjwrtancc  in  the  construction  of  stables ;  and  is  most  con- 
veniently obtained  by  making  proper  apertures  in  the  ceiling,  com- 
municatingwidi  the  external  air;  or  by  means  of  windows,  adapted 
to  tlie  form  und  »izuof  thektable.  It  is  a  bad  mediod  of  ventila- 
tion to  leave  the  iip))er  part*  of  the  racks  open,  so  as  to  commu- 
nicate with  the  roof  of  tW  building,  ns  acurrentof  air  istlum-by

temporary,  that  it  caiiwa  a  greater  flow  of  nervous  i>ower  or

pnmd  tiiicliire  ofmyrr/i. 

ALTERA'!  IVKS  are  medicines  lliat  act  very  fjruihiiillj' upon 
le  constitution,  and  tlierefore  require  to  be  coiitiniied  tor  some 
time.  The  medicines  most  commonly  used  as  alteratives  for  the 
horse  are  antimony,  nitre,  sulphur,  resin,  and  >E(hiop'»  mim-nJ ; 
these  aregenerally  given  together,  particularly  the  three  former. 
The  cases  in  wliicli  iilieratives  are  commonly  employed,  arc 
diseases  of  tlio  skin,  such  as  mange  and  other  itcliitig  humoiirx, 
hide^bound  and  dry,  sinring  coat.  They  are  given  aluo  in 
swellings,  or  humours  of  ttie  Itind  legs,  and  worms.  They  ap- 
pear to  do  good,  by  increasing  the  discharge  of  excrement iitous 
matter  from  the  body,  ihrougn  the  various  emunctories  or  outlets, 
auch  a*  the  boweln,  the  kidneys,  and  the  skin.  From  viewing 
the  subjecl  in  this  light,  1  have  been  induced  to  arrange  them 
under  three  heads;  viz.  laxative  alteratives,  diuretic  alteratives, 
and  diaphoretic  allcraiives.  Were  we  to  coniiueoiu^etves  strictly 
U>  the  common  acceptation  of  the  term  alteratives,  we  should 
describe  them  as  medicines,  which  cure  diseases  by  a  gentle, 
slow,  and  insensible  operation  upon  die  body ;  and  under  tliis 
impression,  it  would  apjiear  unnecessary  to  watch  the  effect 
which  such  preparations  produced  upon  tlie  body.  This  would 
be  a  departure  from  tlie  precept  which  1  have  before  offered; 
viz.  **  tliere  b  only  one  source  from  which  any  precise  or  really 
useful  knowledge  of  the  interesting  subject  of  Veterinary  Medi- 
cine can  be  derived;  thai  h,  a  airrfal  atul  ivtpartial  observatloBf

effects  of  ntfh  mfiiicines.  xchrtlier  simple  or  cotnjtowul,  <u  are  em- 
fiegedfrr  their  remocaL"  Hy  attending  to  this  rule,  1  have  ob- 
•et^red  that  tlu*  mediein<-«  given  as  alteratives  have  generally 
some  visible  t-fCvci  upon  the  bowels,  the  kidneys,  or  the  skin;  the 
dirtsion  of  them,  therefiire,  into  laxatives,  diuretics,  and  diupho- 
reticH  will  be  found  ui>eful  in  practice. 

Laxative  Ai-tf-Rativks  are  useful  in  many  caai:-^  and  may 
iflcn  be  KUbKtilutetl  (»v  piirffatiort  willi  grc«l  advantage. 
WIk'ii  a  horse  is  troubled  with  worms,  and  is  too  weak  to  take 
■ng  medicines,  or  when  he  cannot  be  spared  from  his  work, 
they  are  extremely  convenient,  atid  generally  beneficial.  In 
obstinate  cases  of  yrcaw,  and  in  chronic  iiiflnmnintion  of  the  eyes, 
llicy  often  do  good;  thej' are  generally  serviceable  also  in  couglis 


^iroi

BtranglM,  in  which  disonso  t)>e  throttt  is  oflrii  no  tiiiich  inflamed, 
and  so  verv  sore,  as  to  render  the  exhibition  of  inedielne  by  iW 
mouth  improper.  Clystertj  IioweTcr*  are  often  beneficial  in 
(hoi«  cases. 

In  slinrt,  tliere  are  few  meilicinei  of  more  general  nlilitv  in 
the  diseases  of  horses  than  the  laxative  alterative*,  tbe  most  cflce- 
tual  of  which  is  aloet,  in  the  doee  of  two  or  three  drachms,  with 
an  Mjual  quantity  of  Castile  ut&p. 

DitiRcnc  Alt£hativ£s  are  composed  oCnitre,  mi»faoap,mi\ 
turpentine.  'Iliey  are  employed  in  swellingsof  the  \egi  and  oilier 
parts,  or  as  a  preventive,  in  horses  titat  are  subject  to  such  swell- 
ings; and  iheyareeirenaUo  to  improve  tbecoal  and  general  con- 
dition of  the  animu. 

Though  not  so  efleciual  in  some  cases  as  tbe  preceding,  tliry 
are  certainly  very  convenient  and  innoceni,  anil  produce  so  little 
disturbance  in  iho  body,  thai  a  horse  may  continue  his  work 
while  taking  them,  witliout  l!»e  least  danger,  even  in  the  winiir 
season.  Nor  is  there  any  trouble  in  giving  them ;  as  a  bor§c 
readily  eats  tliem,  when  in  tlie  form  of  a  powder,  with  bis  com. 
Ttw  laxative  aUerative  lias  not  tliis  advant^e,  the  aJoeSr  of  which 
it  is  composed,  being  extremely  bitter,  and  therefore  requiring 
to  be  given  In  the  form  of  a  ball. 

DiAfitoitETic  Alteratives  are  composed  of  medicittes  tlial 
act  on  the  skin,  gradually  increasing  the  insensible  perspiratioRi 
and  giving  n  smoathnH»  and  glou  to  tlie  coal.  The  most  effe^ 
liud  medicineH  of  this  clasi  are  \\k  prei»rations  of  antimony  (sr 
An'timoxv);  hut  theae  may  btt  rendere<l  more  efGcacwus  by 
iH-ing  joined  wiili  Other  medicinn,  «uch  as  cordials,  cam[^ior, 
opium,  &c. 

The  complaint*  in  which  this  kind  oi  alteraiivt  i«  m6Kt  useful, 
are  those  termed  turfeit  and  htde-lound;  they  are  dxo  employed 
t»  remove  an  undue  detennimiiion  of  blood  toaiiy  internal  organ, 
or  to  diminish  genemi  plcthnni. 

Dinpkiirrtii^  alu-raliefn  wlilom  prove  effectual,  titi1c«s  assisted 
by  exercise  atid  good  grooming. 

The  altcrativt«  n-conunemled  by  writers  on  farriery  were  not 
eom]>osed  according  to  the  distinction  we  have  here  made;  but 
laxatives,  diureticK,  Sec.  were  mtx<>d  with  little  discn'niiuaiion; 
thus,  ax  we  have  before  ob«ei'ved,  unlimony,  nitre,  sulphur,  and

an  expectorant  quality,  and  is  therefore  given  in  coughs  and

expectorants.  It  b  certainly,  thougn  weak,  a  very  grateful  sti-

disposed  to  flatulency;  it  is  therefore  an  useful  ingredient  in

(See  Cordials  and  Carminatives.)  The  virtues  of  anise^eed 
are  contained  in  its  essential  oil,  the  dose  of  which  is  about  half  a

A  variety  of  vegetables  hare  been  thought  to  possess  this 
i|uality.  but  I  beliere  without  foundation :  amon^  these  are  bosi 
nu',  savin,  anil  wormwood.     /Ethiop's  mineral,  antimony,  nt-

anlhelminlic  in  dogs,  it  may  probably  be  found  useAil  in  horses. 
Of  all  the  mercurial  preparations,  ealamel  is  by  far  the  best  br 
this  purpose,  and  may  be  given  with  aloes,  soap,  and  some 
aromatic  oil,  with  a  little  ginger.  Many  prefer  giving  llie 
calomel  at  night,  and  the  purgative  tlie  foIlo>fiug  morning. 
Aloes  is  a  gooa  anthetminiie.  A  saline  sub»Ianoe  was  some  time 
ago  introduced  from  India,  as  a  remedy  for  titat  stM^iesofwona 
termed  liotfs.  It  seeina  to  be  composed  of  common  salt  am) 
liver  of  sulphur,  but  does  not  appear  to  deserve  the  high  cha- 
racier  that  was  given  of  it;  though,  like  salt  or  brine,  it  amy 
sometimes  have  Ix-en  found  nn  effectual  anthelmintic. 

Ii  has  been  supp(»ed,  ihst  worms  are  lometimes  generated  in 
consequence  of  ciebitity  in  the  digestive  orj^ns.  Tonics  hare 
tlu'n-fore  been  recommended,  particularly  the  vegetable  billersi 
such  as  bark,  wormwood,  camon)iIe,  Sic  Wbeo  wonits  are  di^

cordial  preparations,  with  a  generous  diet ;  but  whenever  this  is 
done,  there  must  be  proportionate  exercise.  One  plan  of  trealiu

lion  or  common  salt  has  been  recommended  for  this  purpose,  to 
which  may  be  ailcled  two  or  ilirec  drachms  of  aloes.  The  dose  of 
salt  is  about  four  ounces,  in  three  pints  of  water.  Oil  of  tiir* 
Dentine  has  of  late  been  recommended  as  an  anthelmintic,  and 
lias,  I  believe,  been  found  more  efficacious  than  anv  other  medi- 
cine. The  mode  of  pivinj^  It  is  to  keep  the  horse  witliout  food 
for  several  houra,  and  tlicn  to  give  four  ounces  mixed  with  a  pint 
or  more  of  oatmeal  gruel ;  the  day  before  the  horse  is  to  take 
about  ihi-ee  drachms  of  aloes,  with  an  equal  quauiity  of  soap,  in 
order  to  open  the  bowels  moderately,  and  so  that  they  may  be 
io  a  loose  state  at  the  time  the  turpentine  is  given.  .Some 
caution  is  necessary  in  adopting  this  method,  as  in  two  ca^es  that 
Ijave  come  lo  my  knowledge,  the  stomach  appeared  to  have  been 
dangerously  affected,  and  in  one  it  produced  a  degree  of  inflam- 
mation that  proved  tatal.  In  one  of  the  cases  the  turpentine  was 
given  undiluted  when  the  stomach  was  empty.  In  the  second, 
the  horse  was  kept  fasting  a  long  time,  I  believe  twelve  hours  j 
in  the  third,  which  proved  fatal,  the  purgative  given  the  day 
before  appeared  to  have  been  too  strong.  I  would  advise,  there- 
fore, when  oil  of  turpentine  is  given  as  an  aiithehninlic,  that  ihe 
hors«  he  prepared  with  bran  mashes,  as  for  physic;  that  only 
three  drachms  of  aloes,  witli  an  equal  quantity  of  Castile  fionp, 
be  given  the  day  before  ilie  tiirpentiiif,  und  that  when  the  liitter

fasting  as  it  appears  to  have  been  in  one,  if  not  nil  of  the  above 
case*.  Perhaps  a  smalt  bi-an  mash  may  be  given,  about  six  or 
scveniti  the  morning,  and  tlie  luqientine  abouteleven  or  twelve.  *

of  that  kind.  A  variety  of  useful  preparations  is  made  from 
antimony,  many  of  which  are  more  efficacious  than  the  mineral 
itaelf;  among  these  are  antimonial  poioder,  which  is  said  to  be 
the  same  as  Jame^t  powder,  emetic  tartar  (tartarised  antimony), 
hermea  mineral,  or  precipitated  gulpkuret  of  antimony,  oxide  of  an- 
timony,  S;c,  The  most  useful  preparations  are  the  tartarized 
antimony,  commonly  named  emelic  tartar  (see  Emetic  Tab- 
tar),  antimonial  powder,  and  the  sulphuret,  or  common  anti- 
mony, such  as  is  sold  under  the  name  of  antimony ;  but  this 
should  be  finely  powdered  or  levigated,  or  prepared  in  the  way 
chalk  is.  When  antimony  is  thus  brought  to  an  impalpable 
powder,  a  smaller  dose  will  be  sufficient,  and  its  effect  will  be 
much  more  certain.  To  these  may  be  added  the  precipitated 
sulphuret  of  antimony,  though  it  is  seldom  employed,  except  as 
an  alterative.  As  a  fever  medicine  tartarized  antimony  and 
antimonial  powder*  are  certainly  preferable  to  every  other  pre- 
paration, and  are  those  most  commonly  employed.  There  is 
another  fluid  preparation  which  is  ot^n  employed  as  a  caustic, 
formerly  named  butter  of  atitimony,  but  now  muriate  of  anti- 
monv.  The  dose  of  tartarized  antimony  is  from  one  to  two 
drachms ;  and,  though  a  powerful  emetic  in  the  human  stomach, 
does  not  appear  to  excite  nausea  in  the  horse ;  but  given  largely 
is  more  apt  to  affect  the  kidneys  or  bowels.  It  is  considered, 
by  veterinary  practitioners,  as  a  safe  and  effectual  fever  medi- 
cine. The  common  dose  is  about  1^  drachm  or  2  drachms. 
Some  practitioners,  however,  prefer  the  antimonial  powder,  as 
being  milder  and  more  effectual ;  but  I  believe  they  are  both 
perfectly  innocent  in  the  dose  commonly  employed ;  and  joined 
with  nitre  certainly  produce  a  good  effect  as  an  auxiliary  to  that 
important  remedy,  bleeding.  {See  Febrifuges,  or  Fever 
Medicines.)  Both  tartarized  antimony  and  antimonial  powder 
are  occasionally  Joined  with  camphor  as  a  fever  medicine,  and 
sometimes,  but  not  often,  with  opium.  (See  Sudorifics.) 
Tlie  sulphuret  of  antimony  is  inert,  unless  it  meet  with  an  acid 
in  the  stomach. 

ANTISEPTICS  are  medicines  which  prevent  putridity,  or 
remove  it  if  already  begun.  The  most  efficacious  are  bark  and 
oAer  bitters  ;  opium,  wine,  ether,  ammonia,  and  campltor. 

Horses  do  not  appear  to  be  subject  to  those  fevers  which,  in 
the  human  system,  are  termed  putrid ;  so  that  these  medicines 
ate  not  required.  However,  as  in  putrid  fever,  it  is  certain  that 
the  presence  of  very  offensive  fffices  in  the  alimentary  canal  will 
prove  a  source  of  great  irritation  to  the  system ;  and  it  may  also 
here  be  remarked,  that  the  urine,  if  retained  for  any  consider- 
able time,  will  have  a  similar  tendency  to  create  irritation  and 

•  Antimonial  powder  ia  now  rarely  used  in  the  horse,  being  considered  ineflec- 
toal.     It  is,  however,  found  useful  in  thed<^,piLrticulBi\j\adiSUmv«>— ^'n.

AKSKNIC. — Araenicum.  New  name,  Ar«cnioi»  Acid 
There  are  two  preparetioiia  of  arsenic  that  are  principallr  mtdr 
uu!  of  in  veterinary  practioe :  atid  these  are  the  wkiu  anmk,  or 
oridf  of  artenic,  and  llie  ^Uotc  arsenic,  gr  sulpburft  of  arvfm. 
Tlic  latiei-  ifl  a  combination  of  while  arsenic  and  sulphur,  eithft 
natural  or  nrtillcial,  varying  in  colour  according  to  the  propor- 
tion of  sulphur,  which,  when  couaidersble,  gives  it  an  orange  or 
red  colour ;  it  in  then  called  Rathfar^  and  u»^d  as  a  pigment  only. 

White  arsenic  is  obtained  in  the  process  of  roasting  certaia 
or*^  'I'iie  arsenic  sublitneai  and  is  collected  in  chimncT* 
ad»pie<l  to  tlie  purpose  It  is  beautifully  white,  and  very  bcary, 
but  easily  reduced  to  a  powder.  'Itie  powdered  arsenic  of  (m 
iJiop*  is  geiKnilly  adulterated,  and  ought  never  to  be  depended 
ujpon.  Tile  practitioner  tlwuld  always  buy  it  in  die  lump,  wd 
either  powder  it  himself,  or  see  it  done. 

While  arsenic  has  been  connidered  a  good  tonic  for  Itorws; 
aiKl,  thuu}j;h  a  violent  poiion  in  the  human  system,  may  begivca 
to  these  animals  with  safety-  From  ii»  tonic  quality  ii  has  sus- 
pended, or  apparently  cured  t)M>  glanders;  but  its  elTect  in  this 
vray,  1  believe,  i*  never  permanent.  It  is  prudent  to  begin  with 
a  small  dose  — from  two  to  eight  grains.  This  may  be  gradualljr 
increased,  and  conlinuod  iw  lung  its  it  does  not  occasion  irritatH^ 
of  lite  stomach  or  bowck,  or  bring  on  vertigo.  When  1^^ 
symptoms  of  these  complaints  manifest  themselves  tin;  use  of 
arsenic  should  be  immediately  discontinued.  In  experimnitt 
on  glaiidered  horses,  I  have  seen  a  dose  of  two  drachms  given 
twice  a  day,  and  continued  for  a  week  ;  at  which  period  it  pro- 
duced itiflammation  of  the  bowels.  I  have  even  kitown  two 
drachms  given  for  two  or  three  days  successively,  without  any 
violent  effect ;  it  will  sumetimcs,  however,  occasion  great  dis* 
Inrbancc  in  the  stomach  and  bowels,  in  much  smaller  doses,  and 
if  continued  without  carefully  watching  its  cAicct,  may  do  great 
mischief. 

Though  arsenic  has  been  often  given  by  way  of  experiment  to 
glandered  liorscs,  even  in  large  dorses,  wiiliout  producing  any 
violent  tfrei'l,  yet  cases  have  occurred  where  moderate  or  even 
small  doK^  have  occasioned  considerable  disturbance  in  die 
stomach  and  bowels.  In  one  case  I  have  known  it  produce  a 
dial  inflammation  of  the  stomach  in  a  moderate  dose:  the 
groom  liaving  persisted  in  the  use  of  it  af^r  the  injurious  I'ffixt

wbich  it  sometimes  produces  hod  taken  place.  When  arsenic 
disagrees  with  the  stomach  it  causes  loss  of  appetite,  shivering, 
dejection,  uneasiness  in  the  stomach  and  bowels,  which  gradually 
increase,  unless  it  be  discontinued;  in  such  cases  castor  oil,  oat- 
meal gruel,  and  infusion  of  linseed,  should  be  given.  When 
castor  oil  cannot  be  procured,  linseed  oil  may  be  substituted  for 
il^  or  olire  oil.  Perhaps  the  most  efficacious  antidote  to  the  effects 
of  arsenic  is  lime  water,  which  forms  with  the  arsenic  arseniateof 
lime,  an  insoluble,  and  consequently  an  innocuous,  substance. 
Ch^k  and  water  is  likewise  a  good  antidote  to  arsenic,  and 
where  this  cannot  be  obt^ned,  one  part  of  common  soap  may 
be  dissolved  in  four  of  water,  by  weight,  and  given  in  large 
qoantitiee. 

In  reviewing  the  experiments  that  have  been  made  with  ar- 
senic, it  does  not  appear  that  it  has  ever  done  any  good  in 
slanders,  and  that  when  it  has  proved  beneficial  in  farcy,  it  has 
been  given  in  small  doses  from  ten  to  fifteen  grains  or  even  less, 
joined  with  sublimate ;  and  then  the  latter,  that  is,  the  sublimate, 
was,  I  suspect,  the  most  useful  ingredient 

As  the  white  oxide  of  arsenic  is  found,  after  death,  to  adhere 
to  the  coat  of  the  stomach,  it  is  not  improbable  that  a  solution  of 
arsenic  would  be  a  more  advantageous  mode  of  employing  this 
medicine.  The  preparation  generally  known  W  the  name  of 
"Fowler's  Solution  "  may  be  exhibited  in  doses  of  half  a  drachm, 
twice  or  three  times  a  day,  to  begin  with,  and  gradually  in- 
creased so  long  as  no  unfavourable  symptoms  are  perceived. 
TTje  use  of  arsenic  is  contra-indicated  whenever  there  exist  any 
afiections  of  the  lungs,  or  where  febrile  action  is  going  on.  In 
short,  this  being  a  dangerous  medicine  to  trifle  with,  should 
never  be  used  without  the  sanction  of  the  veterinary  surgeon. 
As  s  tonic  *,  it  has  been  strongly  recommended  in  small  doses, 
or  in  solution,  but  it  should  be  given  with  caution,  and  not  until 
the  vegetable  tonics,  such  as  gentian,  columbo,  bark,  cordials, 
wholesome  food,  and  occasionsJly  physic,  have  proved  ineffectual. 
Yellow  arsenic,  finely  powdered  and  mixed  with  lard,  is  some- 
times used  by  ferriers  to  remove  warts;  also  in  fistula  of  the 
withers  and  poll-evil,  but  its  effect  is  sometimes  violent,  and  ex- 
tends beyond  the  diseased  parts,  f

neraliy  prorea  iocnraUe,  unless  the  animal  ts  sheltered  from  the 
weather,  and  fed  partly  or  wholly  on  wholesome  nutritious  food. 
The  astrinfi^ntB  most  usd'ul  in  the  diarrhoea  of  cattle  are  catechu, 
kino,  oak-bark,  pom^anate-bark,  with  aromatics  and  opium, 
joined  with  a  nutritious  diet.  Diuretics  have  been  pi'eecribed, 
■oeh  as  turpentine,  which  probably  may  be  advantageously  joined 
with  tonics  or  cordials.  Astringents  are  often  required  as  ex- 
ternal applications,  as  in  grease,  and  troublesome  itores  about  the 
heels  or  other  parts,  or  thrushes  of  the  frog.  For  such  purposes 
finely-powderoi  alum,  either  alone  or  mixed  with  pipe-clay,  or 
bole-armenic,  may  be  used ;  or  sulphate  of  zinc  or  copper,  finely 
powdered  and  mixed  with  pipe-clay,  chalk,  or  bole,  or  dissolved 
in  water  or  vin^ar.  These  astringents  may  be  occasionally 
mixed  with  lard,  or  wax  ointment,  in  woich  case  they  should  be  re- 
duced to  a  very  fine  powder.  Acetate  of  lead  (sugar  of  lead)  is  an 
excellent  astringent  for  external  use,  whether  dissolved  in  water, 
or  diluted  with  vin^ar  or  spirit,  and  employed  as  a  lotion,  or  with 
lard  or  other  unctuous  substances,  and  used  as  an  ointment.  (See 
Acetate  op  Lead.)  Though  the  sulphate  of  copper  (blue 
vitriol)  is  named  here  as  an  astringent,  it  may  be  rather  consi- 
dered an  etckarotie  or  mild  caustic  when  used  alone  externally; 
bat  it  maybe  so  weakened  by  dilutionas  to  become  an  astringent, 
and  when  sufficiently  weakened  with  water,  may  be  applied  even 
to  the  eyes.  (See  Copper.)  Sulphate  of  zinc  (white  vitriol  or 
copperas)  is  also  an  useful  astringent  when  rendered  mild  by 
mixture  with  water  or  unctuous  substances,  such  as  lard ;  but 
alum  is  still  milder,  and  may  be  used  as  an  astringent  in  powder. 
Sulphate  of  iron  (green  copperas  or  vitriol)  is  a  powerful  astrin- 
gent, and  b  sometimes  used  internally  as  a  tonic.  The  dose 
from  one  to  two  or  three  drachms.  It  is  seldom  employed  ex- 
ternally, and  then  in  solution  only.  From  the  for«^oing  obser- 
vations it  will  be  seen  that  the  distinction  between  tonics  and 
astringents  is  not  very  clearly  marked.  The  mode  of  operation 
of  astringents  on  the  living  body  has  been  erroneously  supposed 
to  be  similar  to  that  by  which  dead  animal  fibres  are  constnnged 
and  condensed.  That  property  of  vegetables  which  is  termed 
astringency,  as  it  relates  to  dead  animal  matter,  results  from  a 
peculiar  principle,  termed  by  chemists  tannin,  and  the  gallic  acid. 
The  former  is  remarkable  for  its  strong  attraction  for  animal 
gelatine,  and  the  latter  for  striking  a  black  colour  with  the  salts 
of  iron.  But  increased  evacuations,  or  a  discharge  of  matter  or 
other  fluid  from  the  skin  or  from  sores,  do  not  depend  merely 
upon  mechanical  laxity  of  the  solids ;  nor  does  the  process  by 
wliich  they  are  restrained  resemble  that  by  which  dead  animal 
matter  is  constringed  or  condensed,  as  in  tanning  hides.  As- 
tringency therefore,  in  a  medical  sense,  is  a  peculiar  power 
exerted  upon  living  matter,  by  which  inordinate  evacuations  or

diBcharges  are  restrained  or  suppressed,  in  a  manner  with  wbidi 
we  are  unacquatnted.  There  are  other  v^elables,  besides  those 
above  prescribed,  that  are  occasionally  nsra  as  astringents,  sncli 
as  tormentil,  bistort,  galls,  madder,  dragon's  blood,  catecho, 
logwood,  &c.,  each  of  which  will  be  noticed  under  its  reapectiTe 
name.  The  term  astringent  is  often  applied  to  those  medicines 
or  preparations  that  are  supposed  to  possess  the  power  of  puttuig 
a  stop  to  haemorrhage  or  bleeding,  either  internally  or  externally 
from  wounds;  these  will  be  noticed  under  the  head  Styptiet.

BALLS.  —  Bolt,  Medicine  is  most  commonly  given  to 
horses  in  the  form  of  a  ball  or  bolus,  the  size  of  which  should  not 
exceed  that  of  a  hen's  egg.  Though  named  a  baB,  it  is  gene> 
rally  rolled  up  in  a  cylindrical  form,  about  one  inch  in  diameter, 
and  two  and  a  half  or  three  in  length ;  but  the  form  of  an  egg, 
perhaps,  is  preferable.  There  is  somedmes  difBculty  in  giving

In  giving  a  ball,  llic  horEc's  tongue  is  drawn  out  on  tbe  off  or

essential  oils,  &c.  But  the  most  serious  inconvenienee  which 
arises  from  giving  balls  thai  hare  been  kept  until  t)>ey  become 
very  hard,  is,  lliat  they  are  liable  to  slick  in  Uie  throat  or  gullet, 
and  thereby  endanger  tite  Itorse's  lite;  indeed,  1  have  known 
Itorses  destroyed  in  this  way. 

Balls  cannot  be  eonveiiiently  given  mdcas  wrappt^l  up  in 
paper:  but  for  this  purpose  the  softest  aud  thinueat  should  be 
ehusen. 

The  balling  iron  may  be  covered  with  cloth  or  listing  to  pre- 
vent the  mouth  from  being  bruued  by  it.  In  Imlding  tlw  ton^

dient,  auch  as  aublinute  or  areenic,  flour  and  paste  may  be  em- 
ployed for  mixing  it  up,  and  a  small  bran  masn  should  be  given 
a  little  before  or  after  it.  After  giving  a  ball,  grooms  sometimes 
press  or  pinch  the  throat  for  the  purpose  of  making  the  horse 
swallow  It :  but  this  should  never  be  done,  as  it  is  apt  to  excite 
coughing,  by  which  swallowing  is  prevented.  The  only  thing 
necessary  after  the  hand  is  withdrawn  is  to  keep  the  mouth  shut, 
and  press  the  nose  downwards,  in  a  moderate  degree,  towards 
the  chest.  Pievious  to  the  composition  of  a  medicine  it  is  neces- 
sary to  consider  whether  its  operation  is  required  on  the  stomach, 
the  alimentary  part  of  the  intestinal  canal,  or  the  large  intes- 
tines. If  on  the  stomach,  a  drench  is  the  best  form ;  if  on  the 
alimentary  canal  or  small  intestines,  a  soft  ball,  containing  a  small 
quantity  of  potash  or  soda,  should  be  preferred,  unless  there  is 
Bny  ingredient  in  the  ball  which  renders  an  alkali  improper. 
There  is  a  quality  in  potash  which  may  be  considered  an  incon- 
venience, but  it  is  really  an  advantage;  a  ball  containing  potash 
continues  soft,  and,  if  kept,  becomes  too  soft  by  the  moisture 
which  the  potash  attracts ;  therefore  it  must  be  given  soon  after 
it  is  made.  In  forming  a  cathartic,  soap  is  the  best  article  that 
can  be  employed,  provided  it  be  not  incompatible  with  the  other 
iDgredients  of  the  ball.  Balls,  made  with  soap,  even  if  kept  some 
time,  may  be  given  without  that  danger  which  attends  the  ex- 
hibition of  old  or  hard  cordial  or  diuretic  balls,  which  do  not 
contain  soap  or  potash ;  therefore,  balls  which  are  intended  to  be 
kept  some  time,  such  as  diuretics,  should  always  be  formed  with 
soap.  Balls  made  with  resin  or  turpentine,  nitre,  &c.,  or  cordial 
balls  made  with  syrup,  and  kept  to  become  hard,  are  not  only 
liable  to  remain  in  the  large  intestines,  causing  the  conglu- 
tination of  the  earthy  matter  contained  in  the  excrement,  or 
serving  as  a  nucleus  for  it,  and  producing  the  large  stones  some- 
times found  there,  but  are  liable  also  to  stick  in  the  cbso- 
phagus  or  gullet,  and  so  low  down,  that  is,  within  the  cavity  of 
the  chest,  as  to  remain  undiscovered,  and  cause  the  animal's  death. 
I  have  met  with  such  cases,  and  was  not  aware  of  the  circumstance 
till  afler  the  horse's  death,  when  I  discovered  the  ball  wrapped  in 
brown  paper  and  firmly  lodged  in  the  lower  part  of  the  oesophagus. 
In  (he  three  cases  I  have  seen,  the  ball  was  of  the  cordial  kind,  and 
two  of  them  wn^ped  in  brown  paper :  in  one  of  them  sulphur  was 
an  ingredient.  One  of  them  was  lodged  about  the  pharynx,  and 
prodneed  a  fatal  inflammation  of  the  windpipe  and  lungs.  Tliis 
DOrse  was  labouring  under  a  severe  catarrhal  affection  at  the  ti  me 
the  bait  was  given,  attended  probably  with  sore  throat,  in  which 
case  no  attempt  should  ever  be  made  to  give  either  balls  or 
drenches.  In  the  other  two  cases  the  balls  were  lodged  in  the 
lower  part  of  the  oesophagus.  The  symptoms  were  those  of 
choking  terminating  in  suffocation.   In  one  instance  the  appetite

r  Mnc<*rate  for  fourteen  days  (seven  days;  Dub.),  and  filter  or 

strain  through  blotting  paper.  The  properties  of  thia  tincture 
are  stimulating  and  expectorant,  and  it  is  therefore  by  some  pre- 
scribed, in  combination  with  other  remedies,  in  caaes  of  old 
chronic  eougii  or  broken  wind.  As  it  is  decomposed  by  water, 
it  ahould  fxvsi  be  amalgamated  with  mucilage  or  yolk  of  egg,  in 
order  to  suspend  it  in  aqueous  liquids,  when  given  internally. 
However,  its  principal  use  is  that  of  a  stimulant  external  appli- 
cation to  indolent  sores  or  wounds. 

Balsam  of  Gilead  is  nearly  similar  to  the  capioy,  but  more 

Eleasaiit.  Many  virtues  liave  been  attributed  to  these  balsams 
y  medical  writers:  lliey  were  supposed  to  heal  ulceration  of  ilie 
longs,  kidneys,  or  oUier  internal  parts,  and  to  be  jjoworful  cor- 
rt^torania.  They  do  not  appear,  however,  to  possess  these  qua- 
lities, nor  do  tliey  seem  lo  differ  much  from  turpentine  in  their 
nuilical  virtues.     See  Tubpentine. 

Balsam  op  Peku.  This  is  of  a  dilTerent  kind  from  the 
funner  baliiams  being  more  stimulating. 

The  dose  is  from  one  lo  two  drachms.  {See  Expectobants 
and  Pfxtokals.)  It  is  sometimes  used  externally  as  an  appli* 
eaiion  to  irritable  ulcers. 

Balsam  of  Toi.u.  This  is  generally  in  a  solid  form,  of  n 
light  yellowi.fh  colour,  and  fraj^rant  odour:  it  is  used  for  the

to  be  relied  on.  .Some  of  the  horses  treated  by  Mr.  Percival

llie  soil  is  calcareous,  flowering  in  June,  and  ripening  its  settl-

acttvitv,  allhuugli  the  leaves  are  commonly  employed  medicinally. 
In  order  to  prc-jHire  the  extract,  these  arc  bruised  in  a  mortar,  a 
little  water  being  poured  over  lliem  ;  then  submiltcd  to  pressure, 
and  the  juice  evajwraied  unlit  it  has  acquired  a  fit  conoist-

"  Proptttits  anil  Utfs,  The  odour  of  this  exti'acl  is  peculiar, 
and  its  taste  bitter.  lis  action  is  that  of  a  narcotic  and  sedative, 
relieving  pain  and  lessening  both  the  force  of  the  pulse  and  ihu 
number  of  its  beats;  hence  its  use  is  indicated  in  all  ihoae  ditc 
eases  where  nn  undue  action  of  the  nervous  and  v,iscular  Ky»cemit

of  from  two  to  four  drachms:  in  larger  doirs  it  acts  gently  on 
the  bowels.  ENtemally  it  is  ^omrluncs  applied  to  ilie  eye,  and 
by  its  influence  on  the  radiated  fibres  of  the  iris  it  dilates  the

generally  employed  in  the  form  of  ointment,  but  on  some  occa- 
sions they  arc  preferred  of  a  thinner  consistence,  or  in  the  form 
of  liniment,  or  even  still  thinner  or  more  fluid,  and  are  then 
named  liquid  blisters.  Formula;,  or  receipts  for  each  of  these, 
arc  subjomed.  Though  a  variety  of  ingredients  are  generally 
used  in  blisters,  1  believe  thai  the  Cantharis,  or  Spanish  fly,  is 
the  best;  and  if  not  injured  by  long  keeping,  or  adulterated,  is 
the  only  blistering  ingredient  required  for  common  purposes. 
Spanish  flies  should  be  finely  powdered,  and  used  while  fiesh.

CARMINATIVES.  Medicines  that  correct  flatuleiicy  in 
the  alomadi  und  bowels.  The  rii^sorder  lor  wluch  carminatives 
are  emploved  is  numeil  JUifulcnt  or  xjjatmtHiic  colic,  also  gripet 
iUtdJ'rH.  This  disease  Iri'Cjiiently  happenn  lo  horses,  and  from 
the  nature  of  it  not  beiny  understood,  often  proves  fatal. 
Wcconsianlly  hear  of  horses  dying  of  inflammiition  of  the  boncls) 
and  this  is  really  the  esse,  but  the  inflammation  is  produced  by 
the  flatulent  colic.  When  str  or  wind  is  generated  in  the  horses 
Moniocli  it  cunnol  escape  upwards  as  in  man,  and  is  prerenleil 
from  |>BSti»g  in  die  oilier  direction  by  a  ^'<l1v(llar  structure  at  the 
part  vriterc  the  small  intestinew  terminate;  that  is,  in  the  caxiim 
or  large  intestines,  whicJi  in  the  horse  is  very  capacious.  As  ili« 
wr  accumulates  it  distends  the  stomach  and  small  intestines,  and 
if  tliey  have  not  sufficient  energy  to  overcome  by  tlieir  contrac- 
tile {wvrer  the  resislancc  made  by  this  valvular  structure,  inflam- 
mation lakes  place,  and  the  animal  dies.  Carminative  mcdiciiies 
increase  for  a  aliort  time  the  vital  power  of  the  siomacli  and  small 
intestines;  put  a  stop  to  the  process  by  wliicli  air  ia  generated ; 
excite  them  to  more  vigorous  coDiractions ;  and  enable  them  to 
overcome  the  obstacle  above  described,  and  expel  the  confined 
air.  It  is  in  this  way  that  carminatives  cure  the  llatutenc  colic. 
Sometimes,  however,  citrminalives  prove  inelTecIual,  not  ol'ion 
From  a  want  of  power  in  the  medicine,  but  from  a  circumstance 
that  IS  not  sufficientlv  attended  to,  that  is,  from  an  accumulation 
of  excrement  in  the  large  intestines.  Tlie  carminatives  usually 
employed  are  by  far  too  strong;  tliey  often  cure  the  disorder, 
but  always  increase  the  tendent^y  to  it  by  impairing  ilie  tone  of 
the  stomach.  Lnr^e  do>eji  of  turpentine  and  other  essential  oils 
are  injurious  in  ihiH  way,  also  pei)pei'  and  other  strong  Ktiniulants.

CASTOR  Oil..  —  Olfum  Hieiiii.  Castor  oil  is  obtained  by 
boiling,  or  by  expression  from  the  seeds  of  ihe  ricinus  or  palma 
Christi,  a  plant  found  in  th«  I'Jwt  and  Wot  Indies,  in  Greece, 
South  Americftt  Africa,  and  on  the  Rock  of  Gibraltar.  The 
former  method  wuk  generally  used  till  lately,  and  was  perf<irmi.-<i 
by  lying  up  the  secdii  in  a  iNig,  (having  previously  taken  otT  die 
t»rk  and  hrni«cd  liieni,]  and  i^uapt-nding  the  bag  in  boiling  water 
till  all  the  oil  was  extracted  and  ro^e  to  the  surface,  when  it  was 
skimmed  olT;  hut  it  is  now  more  generally  obtained  by  pressure 
like  that  of  almonds  or  olives.  Tlie  castor  or  ricinus  seeds  urc 
a  strong  purgative.  The  best  castor  oil  is  made  in  England  from 
cold  blanched  seeds  with  the  eye  taken  out.  It  is  said  that  the 
dark-coloured  castor  oil,  brou'-ht  from  the  West  Indies,  is 
bleached  or  rendered  colourless  bv  some  process  in  this  country, 
and  sold  as  cold-drawn  castor  od.  Castor  oil  is  an  exn'llent 
purgative,  as  it  opens  the  bowels  without  producing  griping  or 
irritation.  It  is  therefore  peculiarly  suited  to  those  disorders  of 
tlie  intestinal  tube  which  require  laxatives.  The  dose  is  from 
half  a  pint  to  a  pint,  or  a  pint  and  a  half. 

It  has  been  a^erte<l  that  cantor  vil  is  a  good  remedy  for  worms ; 
but  1  Itave  seen  it  given  for  this  complaint  without  effect.  It 
has  been  suggested  that  eittier  olive  or  linseed  oil  may  be  sub- 
stituted for  castor  oil :  pcrliaps  they  are  inferior  as  laxatives,  but 
so  macb  cheaper  that  they  ought  to  be  fiiirly  tried.  See

A  horse  should  be  olotlied  and  not  exposed  to  rain  or  cold  wind 
during  tlie  o|)eraiIon  ol'  physic;  and  when  its  o[>era[ioti  has 
ceased,  be  should  be  gradually  brought  back  lo  his  ujual  diet 
and  work. 

Gibson,  Bracken,  and  other  veterinary  authore,  have  prvscriljed 
jalap  and  cream  of  tartar  in  dieir  purging  balls,  Ii  ha^  been 
proved,  however,  that  jalap  has  but  htile  effect  on  the  horse, 
oven  in  a  large  dose  (seo  Jalap);  and  that  cream  of  tartar, 
which  was  supposed  lo  prevent  griping,  by  correcting  the  acri- 
mony of  the  aloes,  ia  absolutelv  useless.  1  ho  neutral  salts,  such 
aa  sulphate  of  soda,  and  sulplialc  of  magnesia  (Glauber's  and 
Epmni  salts),  are  sometimes  employed  by  veterinary  practitioners, 
especially  in  France ;  but  the  large  dose  required  to  nroduee  a 
purgative  edcct  (seldom  less  than  I'i  ox.  or  1  lb.)i  and  the  (llfH- 
culty  and  trouble  in  giving  iheni,  prevent  their  being  much  u>ed 
in  this  countrv.  When  a  horse  can  he  brotighl  to  drink  n  weak 
solution  of  Epsom  salts,  suppose  I  Ik  to  a  large  pail  full  of 
water,  a  diuretic  effect  is  generally  produced,  and  ilie  dung  ii 
little  softened ;  but  when  purging  is  necessary,  nothing  of  the 
sort  should  be  depended  upon.  Common  salt  is  an  excellent 
cathartic  for  catlle,  and  BometimcG  requires  to  be  strengthened 
by  three  or  four  drachms  of  aloes.  The  dose  of  common  salt  for 
calde  is  tlie  same  a£  for  the  horse,  that  is,  from  four  to  six  ounces 
in  one  quart,  or  more,  of  whey  or  water.  Catlisrtics  are  a  most 
important  class  of  medicines:  and  of  all  cathartics  Barbadoes 
aloes  is  the  beat.  They  improve  dipcslion  and  chylification,  by 
cleansing  the  intestines  and  unloading  the  liver,  and  if  the  animal 
is  afterwards  properly  fed,  will  improve  his  «trength  and  condition 
in  a  remarkable  degree.  Cathartics  arc  always  useful  when  the 
appetite  and  digestion  arc  bad,  and  ibis  is  known  by  a  voracious 
or  depraved  appetite,  both  for  food  and  for  water;  rumblmg  of 
the  bowels,  and  n  frequent  diwhai-gc  of  wind  from  iho  anus. 
This  is  the  case  in  a  remarkable  degree  with  broken-winded 
horses,  and  generally  in  such  as  have  chronic  cough,  or  are  crib- 
btters.     Cathartics  sliotdd  not  be  given  too  strong  or  too  fre- 

anently,  as  they  may  thereby  woaken  intiead  of  strengthen  the 
igestive  organs,  unil  produce  the  effect  they  were  inti-ndcd  to 
remove.  Cnihartics  may  b«-  made  with  soap,  in  tltc  following 
niuiiner,  and  then,  if  given  upon  an  empty  stomach,  they  will  be 
carried  off,  and  will  not  be  dissolved  until  tliovget  into  the  largu

tbe  cathanic.  (See  broMACHics.)  Horws  are  more  nsitjr 
purged  in  tbe  mouliing  season  than  at  other  times,  particularlT 
lo  September.  Al  ih^  times  the  bowels  are  weak,  and  a  smsD 
dow  should  be  given.  Mr.  Bracy  Clark's  method  of  mixing 
■loa  Cm*  phj-^c  is  most  eas)' :  and  if  ginger  atid  some  eveniili

be  tltc  bni;  especially  if  ll>e  physic  is  wanted  to  act  only  on  tlie 
lar^  bownU.  Soan  as  well  as  soda  and  potash  promotes  tbe  so- 
lution of  aloes,  ana  causes  it  to  act  on  tlie  small  bowels,  and

It  is  necessary  to  stir  (lie  mixture  well  after  it  has  been  in  the 
boiling  water  a  sliort  time,  and  when  perfectly  melted  and  in-

I  liave  found,  however,  that  by  pouring  l)ie  mixture  upon  a 
marble  slab  or  plate,  previously  greased  with  butter,  it  soon  ac- 
quires n  proper  consistence  to  be  formed  into  balls. 

[Th*;  following  formula  u  rccoinmendcd  by  Mr.  Morton :  — 

Aloes  in  smalt  pieces.. 8  parts. 

Olive  oil 1  part. 

Treacle 0  [mru. 

The  aloes  and  oil  to  be  melted  together  in  a  water  bath,  and 
wbm  removed  from  the  fire  the  treacle  is  to  bo  added,  and  the 
whole  Rtirre<l  together.  When  Cape  aloes  are  usod  Mr.  Morton 
withholds  half  the  oil  and  substitutes  water.  1  have  been  in  the 
habit  of  making  the  caihiirtic  mass  in  a  similar  manner,  but  sub- 
slituling  one  part  of  powdered  ginger  instead  of  an  equal  portiou 
of  oil  and  treacle,  which  I  found  to  form  a  mass  of  letter  con- 
siatcnce  and  less  likely  to  run.  I  have  also  added  a  few  drachms 
of  powdered  tartaric  acid,  the  effect  of  which  has  been  to  assist 
the  union  of  the  mass,  and  prevent  it  adhering  to  the  fingers. 
The  Barbadoes  extract  is  certainly  more  certain  in  its  cfTecta 
than  the  Cape,  but  the  latter  may  be  rcndc'red  ecjually  «>  hy  the 
'  addition  of  croton  oil,  nine  drops  of  which  added  to  nix  drachm* 
of  Cnpc  aloes,  will  render  it  of  the  »anie  strength  as  an  «qual 
quantity  of  Barbadoes  aloes.  ■ —  Ed.]

CAUSTICS  are  sulwu>nce«  that  burn  or  destroy  paru   to 
whicli  tlw-y  are  applied.     The  most  powerful  is  the  retl-not  iron, 
or  actuai  cautery,  which  is  often  employed  in  veterinary  practice 
I     to  remove  spavins,  &c.     (See  Fibing.)     Many  of  the  other 
cautlica  are  [<o^e^ed  of  great  strength,  and  speedily  destroy 
I     ttMMe  parts  to  which  they  are  applied:  such  are  the  pure  alkalies, 
'     pt>ttith,  and  toilti  ;  the  nilphurie  and  nitrous  acids,  or  a  solution  of 
'      filver,  quicAsiha;  or  co/jfier,  in  nitrous  acid.      If  a  solid  caustic  is 
wanted,  nothing  is  more  convenient  ihun  the  tmiar caustic  {nitrate 
of  nicer).     The  milder  caustics  are  more  frequently  useful  than 
those  we  have  mentioned;  such  as  blue  vitriol  (atfptmte  of  topper), 
red  precipitate   {nitrif.  oxide  of  mercury),   burnt   alum,  verdi- 
gris, &c. 

The  strong  cauiitics  are  employed  to  destroy  unhenltliy  or  dis- 
eaaed  parts,  such  as  warts  and  oiner  excrescences,  clean^ting  foul 
ulcers  and  sinuses,  so  as  to  bring  them  to  a  healthy  state,  and

CERATE.  —  Ceratum.  A  term  given  to  certain  ointmenu 
or  salves,  in  which  icax  is  an  ingredienL  It  is  necessary  that 
the  oils  or  &t  with  which  they  are  composed  be  perfectly  fresh, 
and  preserved  in  this  sute. 

CERUSE.  —  Plumbi  Suhcarhtmas.  This  is  a  carbonate,  or 
white  oxide  of  lead,  and  is  commonly  called  white  lead.  It  is 
a  very  strong  astringent,  and  is  sometimes  used  in  ulceration 
of  the  heels,  when  the  discharge  is  thin  and  acrimonious. 

It  is  generally  made  into  an  ointment  with  hog's  lard  and  oil ; 
but  perhaps  would  be  found  more  useful  if  used  in  the  form  of 
a  finepowder.     (See  Lead.) 

CETACEUM.  SpermacetL  This  is  demulcent  and  emol- 
lient, but  is  not  used  internally  in  veterinary  practice.  Its  chief 
aseis  in  the  formation  of  ointments. 

CHALK.  —  Creta.  This  is  an  antacid  and  absorbent.  It 
should  be  finely  levigated,  or  prepared,  as  it  is  termed,  before  it 
is  administered  internally.  It  may  be  given  in  diarrh(£a,  com- 
bined with  opium  and  ginger,  after  the  irritating  matter  has 
been  removed  from  the  intestines  by  purgatives.  Externally  it 
may  be  sprinkled  upon  sores  which  emit  an  excoriating  dis- 
charge, in  order  to  preserve  the  adjacent  parts  from  its  effects. 
The  dose,  internally,  is  from  two  drachms  to  several  ounces.

CLYSTER  or  CLYSTER,—  JTnffma.  This  ujieful  remedy 
is  not  employed  as  ol^en  as  it  ought  to  be,  and  seldom  pro]K*rly 
or  effectually.  In  flatulent  colic  it  is  essentially  useliil ;  and  i( 
i.t  from  this  circumstance  being  too  little  known,  or  not  attended 
to,  Uiitt  flatulent  colic  sometimes  terminates  in  inflammation  of 
tlie  boweb,  and  death.  (Sec  Cakminativks.)  In  suppression  or 
retention  of  urine,  or  in  difficulty  of  staling,  a  clyster  is  the  best 
remedy  that  can  be  employed.  In  sliort,  llierc  is  scarcely  a  dis- 
ease to  which  horses  arc  liable,  lu  which  clvsicrs  may  not  be  ad- 
vantageously used,  either  as  &  principal  remedy,  or  as  an 
auxiliary  to  others.  Tlic  clyster  pipe  and  bladder  i«  the  only 
eflectual  apparatus  I  have  seen.  The  piiic  should  be  one  inch 
in  bore,  and  fifteen  inches  in  length.*  The  ([untitity  of  liquid 
employed  should  be  live  or  six  qnnrts,  an<l  coiisixt  only  of  warm 
water  or  gruel,  with  half  a  pound  of  salt  dissolved  in  it:  or  three 
or  four  ounces  of  »cniia  leaves  may  he  put  into  Iwiling  water 
instead  of  the  »all.  Tlu-rc  i«  sometimes  difliculty  in  iiitroihicing 
tlie  pipe,  gcuc rally  from  hard  excrement  in  the  straight  gut; 
sometimes,  however,  from  the  bladder  being  distended  with 
urine.  In  such  caxes,  patience  and  care  are  necessary  to  ex- 
hibit liic  clyster  effectually,  and  it  may  almost  always  be  accom- 
plished without  raking  or  drawing  out  the  hard  excrement  with

COPPERAS.— 5«/;)A(w  Ferri.  A  term  formerly  employed,

which  has  also,  when  purified,  been  named  salt  of  steel  {sal 
martu),  and  vitriolated  iron.'  It  is  a  very  useful  tonic  in  doses 
of  Arom  two  to  six  drachms,  and  is  thus  given  with  vegetable 
tonics  to  promote  condition.  Sulphate  of  zinc  has  also  been 
named  white  copperas,  but  more  commonly  white  vitriol. 

CORDIALS.  There  are  no  medicines  more  frequently 
employed  than  cordials  and  diuretics,  and  none,  perhaps,  speak- 
ing generally,  that  do  more  harm,  though  productive  of  tem- 
porary good  when  judiciously  employed.  But  with  respect  to 
cordials,  it  is  necessary  to  inquire  what  are  the  circumstances 
which  render  them  necessary,  and  then  we  shall  soon  learn  that 
it  is  immoderate  work,  and  Imd  management  in  regard  to  feed- 
ing ;  by  the  latter  is  meant  the  bad  quality,  as  well  as  the  im- 
moderate quantity,  of  the  hay  that  is  often  given.  This  is  the 
most  prevailing  error  in  feeding.  Next  to  it  is  that  of  not 
allowing  a  sufBcient  quantity  of  (food  oats,  or  not  properly  pro- 
portioning the  allowance  to  the  horse's  labour;  and  thirdly,  by 
giving  too  much  at  a  time,  and  hindering  digestion  by  putting 
the  horse  to  work  immediately  after  feeding,  or  by  feeding  irre- 
gularly, or  not  observing  a  proper  method  of  distributing  the 
daily  allowance  of  food.  The  use  of  cordials,  on  such  occasions, 
is  to  give  temporary  energy  to  the  stomach  and  bowels,  and 
enable  them  to  discharge  their  laborious  duties.  But  how  is 
this  done  ?  by  an  unnatural  excitement  of  the  nervous  system. 
The  other  circumstance  which  renders  cordials  necessary  is 
immoderate  work,  which  is  of  a  more  serious  nature  than 
improper  feeding.  It  is  a  moral  evil ;  and,  if  duly  reflected 
upon,  will,  I  trust,  be  seen  in  that  light.  When  we  consider 
the  form  of  the  horse,  it  appears  evident  that  he  was  intended 
for  the  service  of  man ;  and  it  is  equally  clear,  in  a  moral  light,

well  suited  to  cattle  as  to  horses ;  and  though  much  stnmger 
drenches  are  often  given,  these  will  he  found,  I  think,  of  mm- 
cient  strength.     When  we  consider  tlie  immense  sixe  of  the 


AND   PHAKMACOPffilA.  461 

nimen,  or  first  stomach,  of  the  cow,  we  may  be  led  to  think  that 
these  animals  really  require  the  Herculanean  doses  often  given, 
and  prescribed  by  writers  on  cattle  medicine.  But  the  internal 
sumce  of  the  rumen  has  a  cuticular  covering,  and  consequently 
poBsessee  but  little,  if  any,  sensibility  to  medicine;  and  it  is 
evident,  from  the  structure  and  disposition  of  the  passage  by 
which  the  four  stomachs  communicate  with  each  other,  as  well 
as  from  the  structure  and  economy  of  the  stomachs  themselves, 
that  drenches  pass  quickly  into  the  Jburth  stomach,  and  that  it  is 
through  the  excitement  produced  upon  this  stomach  and  upon 
the  brain,  that  the  muscular  coat  of  the  rumen,  or  first  stomach, 
as  well  as  the  whole  muscular  system,  is  excited  to  more  vigorous 
action.

CREASOTE.  —  Creaaoton.  This  substance  is  obtained  by 
the  destructive  distillation  of  vegetable  matters ;  hence  it  is  found 
in  pyroxylic  oil,  tar,  and  wood,  smoke  giving  to  those  substances 
their  antiseptic  properties.  Its  preparation  is  exceedingly  trou- 
blesome and  tedious. 

ProperHet  and  Uses.  —  Creosote,  when  pure,  is  a  colourless 
fluid,  oily,  and  of  a  peculiar  odour,  resembling  smoked  meat :  it 
has  a  hot  pungent  taste  ;  it  acts  powerfully  on  the  animal  system, 
quickly  destroying  small  animals.  Internally  given  it  is  a  sti- 
mulant and  tonic ;  and  externally,  when  Applied  in  an  undiluted 
state,  it  is  a  caustic ;  otherwise  it  acts  as  a  general  excitant,  and 
an  antiseptic  It  has  also  been  resorted  to  as  a  styptic ;  indeed, 
its  greatest  use  is  as  a  topical  remedy,  being  employed  in  the 
form  of  a  lotion,  a  liniment,  or  an  ointment,  to  foul  ulcers,  such 
as  occur  in  farcy  and  glanders ;  to  cancerous  sores,  such  as  foot- 
rot,  canker,  and  thrushes;  and  some  cubineous  affections,  as 
herpes,  mange,  &c.,  also  for  the  checking  of  caries,  excessive 
suppuration,  and  the  repression  of  fungous  granulations.  It  is 
lik^se  occasionally  dropped  into  the  eye  in  chronic  ophthalmia, 
when  it  operates  as  a  counter  irritant;  and  has  been  found 
efiectual  in  removing  nebulee.  The  inhalation  of  its  vapour  has 
lessened  the  bronchial  secretion ;  and  as  glanders  in  the  human 
subject  has  yielded  to  it  in  the  hands  of  Dr.  EJIiotson,  and,  still 
more  recently,  this  formidable  disease  has  been  effectually  com- 
bated by  Mr.  Ions,  V.S.,  in  the  case  of  his  son,  it  seems  to  be 
worthy  of  a  trial  for  this  affection  in  the  horse,  being  both  given 
internally,  and  applied  locally.  The  dose  has  not  yet  been  as- 
certained. I  should  think  from  ^ss  to  a  drachm  maybe  diffused 
in  a  weak  mucilage  of  gum,  and  administered  twice  a  day.

CUOiON  SKKUS.  —  CrMM  TujUi  Semina.  Croton  is  •

teria  medicft.  He  employs  the  farinaceous  residue,  and  has 
found  five  grains  of  it  equivalent  in  action  to  one  drachm  of 
aloes.  Should  the  seed  be  given,  about  three  grains,  or  perhaps 
a  little  less,  may  be  considered  an  equivalenL  The  expressed 
oil  has  been  said  to  create  considerable  irritation.  Allowing  this 
to  be  the  case,  surely  some  corrective  may  be  conjoined,  and 
thus  a  valuable  agent  be  added  to  the  list  of  veterinary  thera- 
peutics. The  great  value  of  croton  ceruinly  arises  from  the 
capability  of  administering  it  when  no  other  cathartic  can  be 
^ven.  It  may  be  put  into  the  animal's  mash ;  or,  if  it  is  made 
loto  a  tincture,  as  suggested  by  Mr.  Field,  it  may  be  mixed 
vith  his  water. 

A  form  for  this  is  as  follows :  — 

Tincture  of  croton. 

Take  of  bruised  croton  seeds 1  oz. 

Rectified  spirit 16  oz. 

Digest  for  seven  days,  and  filter  for  use.  Dose  from  half  an 
ounce  to  an  ounce.  This  solution  is  also  an  active  counter-irri- 
tant. I  am  inclined  to  believe  that  croton  requires  nearly  the 
same  time  to  excite  the  bowels  that  aloes  do,  from  which  it 
differs  in  not  creating  so  much  nausea,  and  in  producing  a 
greater  liquidity  of  the  dejections.  It  is  therefore  well  suited 
for  anasarcous  swellings.  As  a  general  cathartic,  croton  will 
never  supplant  aloes,  but  a  combination  of  the  two  may  be  found 
of  advantage.* 

For  catUe,  the  union  of  croton  with  the  sulphate  of  magnesia 
in  doses  from  twenty  to  thirty  grains  of  the  seed  is  useful  in  ob- 
stinate constipation. 

The  croton  oil,  if  placed  on  the  tongue  of  a  horse,  in  quanti- 
ties from  twenty  to  forty  drops,  produces  purging ;  but  in  this  way 
it  is  apt  to  iuname  the  membrane  of  the  mouth.  —  Morton's

grated  ginger,  or  a  glass  of  gin  or  other  spirit,  will  be  found  a 
cheaper  and  a  more  effectual  remedy  than  Daffy's  Elixir ;  or, 
what  is  still  more  effectual,  a  pint  of  warm  brandy  and  water;

find  four  drop!)  of  the  oil  added  to  five  drachms  of  Cape  aloes  render  it  equi- 
valent to  five  drftchois  of  Barbadoea  aloes.  —  Ed.

in  a  sufficient  quantity  of  water ;  i.  e.  about  two  or  three  ounces 
to  a  quart  of  water.  This  decoction  is  used  as  an  anodyne  fo-

Decoction  of  Barley.  —  Decodum  Hordei, 

Barley  water  is  made  by  boiling  pearl  barley  in  water.  This 
may  be  used  in  fevers,  either  alone,  or  as  a  vehicle  for  nitre,  or 
other  medicina 

Various  other  decoctions  are  occasionally  employed,  and  some- 
times preferred  on  account  of  tlieir  cheapness,  to  more  efficacious, 
but  more  expensive,  medicines;  yet,  it  must  be  recollected,  that 
some  vegetables,  such  as  peppermint,  penny-royal,  &c.,  have 
their  useful  properties  dissipated  by  much  boiling,  and  should 
therefore  be  only  simmered  for  a  few  minutes,  or  only  infused, 
as  it  is  termed.  (See  Infusions.)  It  is  a  common  practice 
with  cattle  doctors  to  boil  their  drenches  in  ale,  by  which  the 
spirit  of  the  ale,  and  sometimes  llie  essential  parts  of  the  other 
ingredients  are,  in  some  degree,  evaporated. 

DECOMPOSITION  is  the  separation  of  bodies  which  are 
combined  by  chemical  affinity,  and  can  only  be  effected  by  the 
agency  of  some  substance  or  substances  which  have  a  stronger 
affiniw  for  one  or  more  of  ihe  constituents  of  the  compound  than 
these  have  for  each  other. 

DELIQUESCENCE.  When  any  solid  possesses  so  great 
an  attraction  for  water  as  to  absorb  from  the  atmosphere  a 
quantity  sufficient  to  dissolve  it,  it  is  said  to  deliquesce.  Those, 
again,  that  part  with  their  water  of  crystallization  until  ihey  be- 
come dry  and  fall  into  powder,  arc  said  to  effloresce.

added. 

DIAPHORETICS.  Medicines  that  increase  the  natural 
discharge  by  the  skin;  which,  when  they  act  in  so  considerable 
a  degree  as  to  occasion  sweating,  are  termed  sudorifics. 

It  is  extremely  difficult  to  produce  any  visible  effect  upon  the 
horse's  skin  by  means  of  medicine  alone ;  but  when  it  is  assisted 
by  proper  exercise  and  warm  clothing,  we  can  generally  give  a 
fiiie  glossy  appearance  to  the  coat,  though  it  is  very  difficult  to 
produce  sensible  perspiration,  unless  it  be  by  violent  exercise, 
and  immoderately  warm  clothing.  The  most  effectual  diapho- 
retics in  tile  horse,  are  medicines  of  the  hot  stimulating  kind, 
combined  with  antimonial  preparations  and  opium ;  these, 
however,  cannot  be  employed  with  propriety  in  fevers,  which 
are  generally  an  effect  of  internal  inflammation ;  they  are  useful 
only  when  horses  are  hide-bound,  have  a  rough  dry  coat,  and 
appear  in  a  state  of  debility.  The  elfects  of  this  class  of  medi- 
cines are  so  very  uncertain  in  the  horse,  and  so  rarely  succeed 
unless  assisted  by  exercise,  that  it  seems  probable  ihat  exercise, 
a  proper  diet,  and  good  grooming,  form  the  only  effectual  dia- 
phoretics. 

Emetic  tartar  and  other  preparations  of  antimony,  Minde- 
rerus's  spirit,  or  water  of  acetate  of  ammonia,  and  camphor  are 
the  diaphoretics  which  are  employed  in  febrile  complaints.  See 
Febrifuges.  • 

DIGESTIVES.  Medicines  which  promote  snppuration  in 
ulcers,  and  cause  them  to  discharge  a  white  healthy  matter. 
TTiis  term  is  commonly  applied  to  ointments  and  other  prepara- 
tions which  improve  the  slate  or  condition  of  ulcers  or  sores, 
and  cause  them  to  discharge  good  matter.  Medicines  that  pro- 
mote the  digestion  of  food  are  named  tonics,  stomachics,  and 
cordials.

DISTILLATION.  An  operation  by  which,  thVongfa  Om 
agency  of  beat,  the  fixed  and  volatile  principles  contained  in 
any  body  are  •eparately  obtained. 

DIURETICS.  Mfdieines  that  increase  the  secretion  of 
urine;  an  effect  more  readily  produced  in  the  horse  than  in  the 
human  tiody.  'Hiere  is  a  great  variety  of  medicines  that  act 
oi  diuretics :  the  principal  are,  llie  various  kinds  of  turpendii^ 
balsam,  soap,  the  fixed  alkalies,  nitre,  &c. 

Diuretics  are  much  nsecl  in  veterinary  practice,  particnlarly 
in  diffused  swellings  ofilielegsor  other  parts,  and  grease:  wbtn 
given  in  moilerate  doses,  they  may  be  continued  for  seveial 
days;  and  a  horse  may  work  without  danger  during  their  (ite- 
ration. The  diuretic  ultcrativc  in  our  Pharmacopoeia  is  an  ex- 
cellent me<]icine  for  horses  that  are  subject  to  swellings  of  the 
legs,  and  in  slight  coses  of  grease;  but  in  more  violent  cone- 
plaints  we  must  employ  more  active  remedies,  these  being 
adapted  only  to  mild  coses  which  do  not  prevent  a  horse  fnxn 
working.  However  paradoxical  it  may  appear,  there  is  truth  in 
the  assertion  that  diuretics  arc  among  the  most  useful,  and  like- 
wise the  most  mischievous  nicilicines,  that  are  given  to  horsa 
They  are  extremely  useful  in  carrying  olF  the  impurities  and 
Bimerfiuous  serum  from  the  blood,  thereby  producing  the  best 
effects  in  many  diseases. 

Horses  that  have  good  appetites  will  take  a  diuretic  in  tite 
fomi  of  powder  with  ilieir  food,  and  this  form  should  then  be 
preferred. 

DIUHETIC    POWDER. 

Powdered  resin  and  nitre,  of  each  4  dr. 

Mix  for  one  dose,  and  let  it  be  repeated  daily,  until  a  suffi- 
cient effect  is  produced. 

DIURETIC    BALL. 

Hard  soap  and  common  turpen* 
tine,  of  each    4  dr. 


AND    PHAKMAC0F(E1A.  469 

Powdered  caraway  seeds  enough  to  form  the  ball.  Mix  for 
one  dose. 

CORDIAL    DIURETIC   BALL. 

Hard  soap  and  common  turpen- 
tine, of  each    4  dr. 

Ginger    1  dr. 

Opium     ^  dr. 

Powdered  caraways  enough  to  form  the  hall. 

Diuretics  should  not  be  kept  till  they  become  hard,  as  they 
of^en  are,  but  be  given  in  rather  a  soft  state,  and  recendy  made. 
They  should  also  never  be  so  given  as  to  operate  while  a  horee  is 
in  work,  as  he  may  thereby  be  prevented  from  staling  when  he 
bas  occasion:  from  neglecting  this  precaution,  and  from  their 
frequent  and  immoderate  use,  arise  those  mischievous  effects 
before  alluded  to.  The  kidneys  are  oflen  materially  injured  by 
them,  as  well  as  the  bladder. 

DRAGON'S  BLOOD.  —  Sanffuis  Dracmis.  A  resinous 
substance  of  a  dark  red  colour,  which,  when  pure,  is  entirely 
soluble  in  spirits  of  wine.  Dragon's  blood  was  formerly  em- 
ployed as  an  astringent  and  styptic,  in  fluxes  and  inlernal  bleed- 
ings ;  but  modem  practitioners  scarcely  ever  use  it.  It  is  still 
employed  by  farriers,  in  the  complaint  of  homed  cattle,  which 
ihey  term  red-water,  or  bloody  urine,  but  without  effect;  nor  is 
there  any  disease  of  the  horse  in  which  it  is  likely  to  be  useful. 

DRASTIC.  A  term  applied  to  those  medicines  that,  by  the 
violence  of  their  action,  produce  liquid  purges.  Their  use  is 
particularly  indicated  in  dropsy,  in  which  disease,  by  determin- 
ing a  large  quantity  of  the  fluids  of  the  body,  to  the  intestinal 
canal,  and  subsequently  causing  it  to  be  voided,  the  symptoms 
of  this  complaint  are  greatly  mitigated.  Diuretics  are  chiefly 
used  in  dropsy,  but  when  the  kidneys,  either  from  disease  or 
want  of  tone,  do  not  act  with  sufficient  vigour,  drastic  cathartics 
are  of  the  greatest  utility. 

DRAUGHTS.     See  Drench. 

DRENCH.  A  medicine  in  a  liquid  form.  This  is  an  in- 
convenient method  of  giving  medicine  to  horses,  some  part  of 
the  dose  being  generally  wasted.  It  is  preferable,  however,  on 
many  occasions,  to  every  other  form,  on  account  of  the  medicine 
acting  in  much  leas  time  than  in  a  solid  form:  in  flatulent  colic, 
or  gripes,  for  example,  where  the  symptoms  are  extremely 
urgent  and  alarming,  a  proper  drench  will  soon  relieve  the  ani- 
m3,  while  a  ball,  unless  sofl  and  very  soluble,  would  not 
produce  any  effect.  Farriers  commonly  compose  tlielr  drenches 
with  ale,  whatever  the  qualities  of  the  other  medicine  may  be, 
which   is  often   improper,  since  the  properties  of  the    liquid

Bottles  are  tomctiinet  usml  on  an  emergency  to  give  drencbn; 
but  thvy  arc  attended  witlt  danger,  and  slwuld  be  bandied  cau- 
tioiKly.  In  giving  a  dreiicb,  the  Iwrse's  tongue  should  beheld 
with  the  left  hand;  and  when  the  head  is  dutticieiitly  elevatcdi 
the  nifilieiiie  ia  to  l>e  carefully  |>ourcd  into  the  throat,  imme- 
diately iKtiiig  go  the  tongue,  while  il*e  head  is  kept  up  until 
the  (Iri-iich  ia  swallowed.  Drenchei  are  vorv  addom  given  with 
dexterity,  and  great  part  of  the  medicine  is  sometimes  wasted. 
Every  groom  should  learn  to  give  them  with  facility,  and  alwsji 
keep  a  proiwr  instrument  in  ilie  stable.  In  giving  a  drench, 
the  head  should  not  be  kept  w  high  as  it  generally  is  nor  should 
the  ihroal  be  pressed  or  rubbed,  us  it  often  is,  with  a  view  to 
make  the  horse  swallow,  as  it  is  apt  to  excite  coughing.  In 
severe  colds  or  sirsnclcs,  there  is  orten  some  degree  of  soreness 
or  inflammation  of  the  throat,  by  which  swnllowmg  h  rendend 
difficult  and  painful.  In  such  cases,  no  attempt  should  be  mack 
to  give  either  a  drench  or  a  ball,  as  the  complaint  would  be  ti^ 
creaseil  by  it ;  nnd  if  ut  any  time  a  horse  happens  to  cough  or 
appear  dtntrossed,  while  taking  a  drench,  hin  head  sliould  ba 
immediately  let  down.  Hot  stimulating  mt^^Ucines,  or  such  at 
are  very  nauseous,  are  better  given  in  the  form  of  balls  than 
drenches.  Drenches  should  always  be  given  with  as  much  geiv 
tleness  aa  posfible;  the  horn  may  generally  be  introduced  with 
caw,  Tuerely  by  pressing  down  the  tongue  with  the  Angers  of 
the  left  han<l,  instead  of  dragging  it  out,  as  is  commonly  done. 
A  small  quantity  only  of  the  liquid  should  be  given  nt  once; 
about  six  or  eight  ounecfl,  or  even  less,  when  tincture  of  opitim, 
or  any  powerful  medicine  is  given;  and  it  is  of  importance  to 
be  accurate  in  tlie  dose,  and  not  give  either  more  or  less  Ihmi  a 
certain  quanUly.*

Markfaam's  drench  for  Anasarca,  or  general  dropsy,  consists 
of  a  decoction  of  wormwood  in  ale,  boiled  down  to  two  quarts,

and  into  this  mixture,  6  drachms  of  powdered  Grains  of  Paradise 
(greater  cardamom  seeds),  and  a  similar  quantity  of  long  pepper, 
are  to  bestirred.  The  whole  of  this  drench  is  to  be  given  fast-

DRESSING.  An  operation  of  some  importance  in  the 
management  of  horses ;  and  consists  in  currying,  brushing,  and 
wbping  them,  when  kept  in  the  stable.  This  is  done,  not 
merely  with  a  view  of  removing  the  dust  that  may  be  collected 
on  the  coat,  but  to  keep  up  a  healthy  degree  of  action  in  the 
perspiratory  vessels,  or  pores  of  the  skin.  When  this  is  neg- 
lected or  improperly  done,  the  perspirable  matter  hardens  or 
thickens,  and  remains  about  the  roots  of  the  hair,  and  has  the 
appearance  of  a  whitish  dust  or  small  scales,  which  of^n  cause 
an  itching,  and  make  the  skin  feel  dry,  and  the  coat  appear 
coarse  or  wiry,  instead  of  being  soft  and  shining,  as  it  is  in  a 
horse  that  is  properly  dressed  or  groomed.  Horses  that  are  not 
properly  exercised  have  the  more  occasion  for  good  dressing ; 
ana  the  operation  is  more  easily  and  more  efTectually  performed 
when  a  horse  has  been  previously  exercised  until  he  perspire 
moderately.  Notwithstanding  the  improvement  which  r^ular 
and  careful  dressing  makes  in  a  horse's  appearance,  it  is  not

rially  assisted  b^  exercise  and  moderately  warm  clothing.  I 
have  lately  successfully  employed,  as  an  alterative,  tlie  common 
Eulphuret  of  antimony,  finely  levigated,  or  brought  to  an  impal- 
pable powder  by  washing,  as  challt  u.  M.  Volpi,  an  eminent 
Italian  veterinary  author,  and  one  of  the  Professors  of  the  Ve- 
terinary School  at  Milan,  frequently  prescribes  emetic  tartar  in 
doses  of  four  or  five  drachms  for  horses,  and  much  larger  doses 
for  cattle.  To  a  sheep  he  gives  thirty-six  grains,  to  a  pig  a 
scruple,  to  b  large  dog  six  grains,  and  observes,  that  "  when  the 
nature  of  the  disorder  is  well  known,  and  the  attack  is  severe 
and  dangerous,  we  may  begin  with  much  larger  doses,  even 
four  times  the  quantity  above  prescribed." 

[These  large  doses  of  emetic  tartar  are  to  be  reprobated,  for 
instances  have  been  known  of  inflammation  of  the  stomach  and 
intestines  having  been  produced  by  the  too  large  exhibition  of 
the  medicine  medicinally.  We  are  less  surprised  at  this  when 
we  consider  the  irritating  effects  of  this  medicine,  when  applied 
externally.  In  the  form  of  an  ointment,  or  in  a  liniment,  with 
oil  and  spirit  of  turpentine,  it  has  been  found  to  produce  great 
counter^irritation,  and  to  succeed  in  doing  so  when  cantharides 
has  failed.  In  these  cases  it  is  very  useful,  particularly  as  it 
causes  less  pain.  It  does  not  raise  watery  bladders,  but  pustu- 
lar swellings ;  and  it  is  objectionable  on  account  of  its  tendency  ■ 
to  produce  extensive  sloughing  and  blemishes. ■'»  En.] 

EMOLLIENTS.  Medicines  or  applications  that  soothe 
and  allay  irritation,  by  relaxing  or  softening  the  parts  to  which 
they  are  applied.  They  consist  chiefly  of  oily  and  mucilaginous 
fluids,  which  are  used  either  internally  in  innammaliotis  of  the 
gullet,  windpipe,  intestinal  canal,  or  urinary  bladder,  or  exter- 
nally as  fomentations  or  poultices  (see  Fomentation  and 
Poultice),  at  a  temperature  that  is  most  agreeable  to  the  feel- 
ings of  the  patient,  and  best  adapted  to  the  purpose  for  which 
th^  are  employed,  that  is,  to  assuage  pain,  subdue  inflammation, 
and,  in  tumours  tending  to  suppuration,  to  hasten  or  promote 
that  process.  Emollient  fomentations  are  generally  made  with 
msrsh* mallows,  and  other  mucilaginous  plants  or  herbs;  and 
poultices  are  composed  of  bran  with  oatmeal,  linseed  powder, 
lard,  or  oil,  and  some  of  the  bulbous  roots,  such  as  the  white 
lily,  or  turnip,  with  linseed  meal,  or  bread  and  milk.  Internal 
emollients  consist  also  of  oily  and  mucilaginous  fluids,  or  decoc- 
tions of  marsh-mallow  root,  liquorice  root,  linseed,  solution  of 
gum,  emulsions,  &c.  Their  action  is  the  same  as  demulcents. 
(See  Demulcents.) 

EMULSIONS.  A  term  given  to  preparations,  in  which  oil 
is  blended  with  water,  by  means  either  of  mucilage,  the  yolk  of

potash,  and  tincture  of  opium. 

An  elegant  and  pleasant  emulsion  is  made  by  rubbing  blanched 
almonds  (that  is,  almonds  that  have  had  the  skin  taken  off  by 
steeping  them  in  hot  water)  in  a  mortar  with  sugar,  and  muci-

are  generally  mixed  with  woody  and  other  extran^ons  matter. 

Kiiphorbium  is  used  in  veterinary  practice  as  an  exteriinl  ap- 
plication. It  is  fiyncrally  employed  in  the  form  ol'  tincture; 
sometimes  it  is  mixed  into  an  ointment  with  liog's  lai'd,  iiiei'- 
curial  ointment,  oil  of  origanum,  oil  of  bay,  Dec,  beinj^  pre- 
vioiislv  reduced  to  a  fine  powder.  It  is  also  fi-eqiiei)ily  an 
ingredient  in  strong  blisters,  to  which  it  proves  a  powerful 
auxiliary.  In  whatever  form  euphorbium  is  employed,  it  pi-ovt>s 
oxirentcly  ncriinonions  and  stimulating,  and  is  therefore  em- 
ploT«-<l  lo  reduce  callous  swellings  of  the  buck  sinews,  or  other 
parlK  ;  curbs,  wimlgalls,  &c. 

Tt»c  tincture  is  made  by  digesting,  or  stt-cping,  oik-  ounce  of 
the  powtk-r  in  four  or  six  ounces  of  rccliiicd  or  proof  spirit;  fro-

Htrnim-d  off,  and  kci>i  wril  corked.  Some  add  to  this  a  little 
Stiblimaie  and  oil  of  origaniiin,  or  camplior.  There  is  another 
kind  of  tincture,  made  by  dig<'»ting  the  powder  in  a  strong 
solution  of  potash,  which  also  acts  irery  violently.  In  powdering 
eu[^inrbium,  llie  mortar  should  be  placed  where  there  is  a  cur- 
rent of  uir,  BO  ibat  the  dust  which  arises  tnay  be  blown  off, 
otherwise  it  wonld  get  into  tW  nosinis  or  throcil,  and  prove  ex-

FIKING.  A  severe  operation,  often  performed  on  the  horse, 
and  on  soum-  oeciuions  highly  useful.  It  eongixts  in  the  appliea> 
tion  of  a  red-hot  iron  to  the  skin,  »»  lu  to  burn  without  peiie-

rouM-ti  the  absorbent  vessels  into  itction,  by  which  callous  or  even 
bony  swellidgs  are  sometimes  dispeised.  Tlu>  di^eaies  in  which 
it  is  most  eliicacious  are  spavins,  ring-bones,  and  old  callous 
swelling*  about  the  back  sinews,  in  consequence  uf  trains  and 
windgalls.  Tiring  draws  blood  to  the  tiffected  part,  thickens 
and  strengthens  it,  and  makes  the  skin  act  a*  a  permanent  hand- 
age.  A  blister  is  often  applied  to  the  part,  innnediately  alier 
firing,  or  on  tlie  following  day,  to  render  it  more  elletiual.  Ic

callous  swellings  of  the  back  sinews,  the  swelling  should  bo

Tlw  emollient  fomentation  is  adapted  [o  inflamed  swetlrng«i 
from  whatever  cause  ihey  may  arise;  and  when  it  caiuiot  bp 
procured,  warm  water  alone  will  be  found  an  uwful  substitute. 
The  anodyne  fomentation,  No.  I.,  is  of  ereat  sen-ice  in  wounds 
or  swellings  which  are  accompanied  with  great  pain  and  irrita- 
bility: it  tends  to  correct  putridity  and  gangrene,  in  larger 
wounds  of  the  lacerated  kind,  where  the  matter  is  thin,  ill-co- 
loured, and  offensive;  but  in  such  cases,  the  assistance  of  inter- 
nal remedies  cannot  he  dispensed  with. 

It  is  probable  that  warm  water  U  as  good  an  emollient  fomenta- 
tion as  can  be  employed,  if  used  assiduously,  and  at  a  proper  lem- 
peratur*-,  wliich  should  be  regulated  by  the  slate  or  irritability 
of  the  part  to  which  it  is  applied.  In  inflammalion  of  the  eye,  for 
example,  it  should  not  be  above  Htl",  or  blood  heat;  in  inflamed 
and  painful  swellings,  it  should  seldom  exceed  100°.  In  strains 
of  the  back  sinews,  vinegar,  either  alone  or  diluted,  is  considei'ed 
B  good  fomentation;  and  as  the  injui-}'  U  rather  deeply  seated, 
and  not  in  the  skin,  the  fomentation  may  be  applied  rather 
'liotter  than  wheri?  the  cuticle  i»  affecied. 

When  a  fomentniion  i*  employed  tor  intlainmation  of  the 
bowels,  it  should  be  still  hotter;  indeed  so  hot  as  that  tlie  hand 
cannot  be  dipped  into  it  without  pain.  The  beat  mode  of  ap-

a  steam  fomentation,  and  will  be  found  very  beneficial.  Two 
men,  one  on  each  side  the  horse,  are  required  to  apply  this  (b-

jury is  not  extensive,  the  fomentation  may  be  applied  with  a 
large  sponge  in  others ;  by  a  thick  woollen  cloth,  such  as  an  old 
rug  or  blanket.

very  ratvly  used  for  velerinarv  purposes,  as  it*  dTvcU  are  uo-

The  dose  is  from  two  draclmis  to  half  an  ounce ;  or  two

GKNTIANj  the  Root. —  Grntiann  iMtta.  A  perennial 
phtnt,  found  in  Swiuerland,  Aneiria,  the  Pyrenees,  and  North 
America.  It  pos»-«M-K  no  particular  odour,  and  its  taste  is  ex- 
tremely bitter,  un  which  accotnit  it  is  very  generally  employed 
in  the  same  manner  as  bark  and  other  bilters,  to  give  vigour  to 
the  stomach  and  improve  digestion.  It  generally  requires  to  be 
joined  with  stimulant* ;  such  as  ginger,  esssia,  myrrh,  cascarillA, 
&c. ;  and  when  any  acidity  is  suspected  to  exist  in  the  stomach, 
a  small  quantity  ofsoila  is  an  useful  addition.  Gentian  is  tlu' 
basts  of  that  famous  liorH*  powder  termed  diapenti.  Gentian 
root  sometimes  becomes  rotten  and  uteU-ss :  the  purchaser  shoidd 
tlicrefore  examine  before  he  buys,  and  clioow  such  parts  as  are 
sound,  rather  lough,  and  cxtreiively  bitter.  It  U  to  be  leared 
that  the  powdered  gentian  of  the  shops  is  oot  so  good  na  it 
should  be;  and  it  is  to  be  lamented  that  druggists  in  general 
think  any  thins  good  enough  for  lior!«s. 

The  dose  of  pure  gentian  is  from  two  lo  four  drachms.  Ijee

the  Continent  than  in  this  country :  and  I  am  not  aware  that  it 
has  yet  been  introduced  here  into  veterinary  practice ;  but  it 
certainly  deaervet  a  triaU  especiailv  aa  it  is  an  indigenous  plant, 
and  elioiild  iberefore  be  sold  at  a  tow  price. 

GINGER;  llic  Root. —  Zingiber  officinaliM.  This  plant  '» 
originally  a  native  of  the  East  indies,  but  is  now  very  exten- 
sively grown  in  the  West  Indies  also.  TTie  root  only  is  tised  in 
medicine,  and  tlii«  is  prepared  in  two  ways,  producing  two  son* 
ofgiiiffcr,  the  white  and  tite  black.  The  former  is  generally 
employed  for  cuHnnry  purposes,  and  the  latter,  being  the 
cheapest,  is  mwtl  frctpiently  used  a«  a  horse  medicine. 

I  consider  ginger  as  the  most  useful  stimulant  in  the  veteri- 
nary materia  mrdtca ;  when  joined  with  aromatics,  such  as  alUpice, 
caraway-«eitl,  auise'Sced,  ctinimin-seed,  &c.,  or  their  essential 
oil*,  it  forma  nn  elHrjiciou*  conlini;  and  nilh  emetic  tartar  and 
o]>ium  an  excellent  dinphu relic,  for  giving  gloss  to  llie  coal,  and 
relaxing  the  sktti. 

Ginger  h  extremely  heneiicial  in  weakne«»  and  flatulency  of 
the  ttomach ;  and  aB!ii*ied  by  other  rvniedie«,  such  as  warm 
brer,  it  seldom  fails  of  curing  the  flatulent  colic  or  gripes.  (See 
Carmin'ativks.)  It  is  generally  added  to  aperients,  in  order  to 
correct  thrir  liability  to  produce  griping. 

Th*'  dose  \»  from  one  drachrn  to  three  (Irachms. 

It  should  he  recently  {Wttdered  when  used;  hut  in  a  wcll- 
Klopped  bottle  the  powder  may  be  kepi  a  considerable  lime 
witnout  losing  its  strengtii. 

Ginger  is  frequently  thrust  whole,  after  being  chewed,  np  the 
fundinnent  of  a  hone,  in  order  to  make  him  carry  his  tail  high, 
and  give  him  a  eighily  appearance.  It  is  certainly  a  very 
improper  practice,  and,  though  il  may  very  rarely  happen,  1 
can  easily  conceive  that  a  very  considerable  degree  of  irrilation 
of  the  rectum^  and  tenesmus,  may  be  produced  by  a  frequent 
repetition  of  this  operation.  Many  horses  belonging  to  dederi 
are  frequently  shown  to  customers  a  dozen  times  a  day,  or 
of^er,  and  are  invariably ^^fi/,  as  it  is  termed,  prior  to  being 
led  out  of  the  stable.  After  il  sliort  linie.  the  irritation  produced 
by  the  ginger  causes  them  to  m<ike  violent  efforts  to  dung,  and 
the  ginger  is  generally  expelled  :  but  these  very  etforts  prove  to 
wltat  a  ftlimuluB  the  poor  animals  have  been  euhjcctcd ;  and 
stimulants,  especially  strong  ones,  frequently  n>pcatcd,  may 
even  I  iially  produce  inflanimation.

the  extract  to  a  pint  of  rain  or  river  water  ;  some  add  to  tliis  a 
little  camphorated  spirit,  or  some  distilled  vinegar ;  but  when 
the  lotion  is  intended  for  the  eyes,  there  must  be  a  much  Ui]ger 

tiroportion  of  water,  not  less  than  a  quart,  and  the  lotion  dioold 
le  filtered. 

Goulard  poultice  is  made  by  mixitig  as  much  of  ilie  lotion, 
with  bran,  linseed  meal,  or  any  proper  materials  for  a  poultice^ 
as  will  give  them  a  proper  consistence.  (See  Poultices  and 
Lotions.) 

Goulard  Is  never  used  undiluted,  nor  is  it  given  internally. 

GRAINS  OF  PARADISE.  —  Car^amomum.  A  waira 
Stimulating  seed,  often  used  in  the  diseases  of  horned  cattle  as 
a  cordial;  and  where  medicines  of  that  kind  are  required,  it 
is  certainly  very  proper. 

The  dose  is  from  tliree  to  six  drachms,  or  one  our>ce. 

GRUEL  is  an  useful  drink  for  horses  on  many  occasions; 
and  when  made  carefully,  or  sweetened  with  sugar  or  treacle, 
and  eometiuies  seasoned  with  salt,  they  wilt  often  drink  it,  and 
save  the  trouble  of  drenching.  It  is  a  good  vehicle  for  such 
medicines  as  are  of  u  stimulalmg  or  acrimonious  nature,  such  as 
oil  of  turpentine.  Gruol  is  made  citl>er  with  oatmeal  or  groats, 
barley-meal  or  pearl-barley,  fine  wheat  flour  or  arrow-root;  it

gruel  made  with  it  haa  often  some  degree  of  bitterness.  Wbeit 
gniel  ia  given  as  a  cordial  restorative  after  bard  work,  a  little

ore  exbaualed  by  long  fasting  and  fatigue  are  soon  recniited  by 
taking  sucb  gruel.  Horees  are  very  nice  in  ibeir  drinking; 
therefore  the  gruel  should  be  made  in  a  clean  saucepan,  free

where  it  is  inconvenient  to  boil  the  gruel,  a  little  oat,  barley,  or

It  is  a  good  practice  to  accustom  horses  to  drink  gruel,  a*, 
after  a  hard  day,  miuiy  hunters  show  a  disinclination  to  eat,  but 
will  drink  with  avidity;  and  if  they  will  drink  gruel  instead  of 
water,  it  is  not  of  much  consequence  if  they  fast  for  some  time. 
No  horse,  it  should,  however,  be  remembered,  is  fit  for  hard 
work  if  he  be  not  a  good  feeder;  but  the  best  horse  may  refuse 
liis  food  if  forced  to  over-exertion. 

GUv\IAC. —  Guaiacmn  offkinair.  This  tree  is  a  native  of  Ja- 
maica, Ilispaniola,  and  some  parts  of  America.  Every  part  of  it 
poGsestes  medicinal  properties,  but  the  wood  and  gnm  alone  are 
uwd.  The  former  is  sometimes  employed  in  hnmnn  medicine, 
as  an  ingredient  in  aJterative  decoctions,  hut  never  in  veterinary 
practice.  Tlie  resin,  commonly  called  ffum  tfiutiaaim,  is  some- 
times used  as  an  alterative.  I-nrrier:  employ  it  also  in  what 
they  suppose  to  be  rheumatic  lameness,  but,  I  believe,  without 
any  advantage. 

The  doee  of  gum  giiaiaciim  is  from  half  an  otmce  to  six

HELLEBORE,  BLACK  AND  WHITE.  —  i/fffAiriB 
Nii/«r,  Vemtrum.  Black  hellebore  is  a  native  of  Austria,  liie 
A|)enninps,  and  Italy;  white  Itelleboreof  Greece,  Italy,  Snilier- 
lai)d>  and  Iliiuia.  TlM-y  both  net  as  drnstic  calharlica  and 
emetics  on  the  human  frante.  producing,  in  large  doses,  vertigo, 
inflanimalion  of  tlic  Ktoniach,  and  coiivulsionif,  I'he  root  of 
this  plant,  {Mtrticularly  of  white  liclicborc,  is  extremely  acrimo- 
nious; for  if  wounded  wbilc  frcsli  it  emits  a  juice  capable  of 
blUteriug  the  ^kiii. 

Powdered  while  hi-llflwn.-  in  often  eii))i]»y<<<l  as  an  ingredient 
in  blisters.  It  is  UM-d  nlito  in  oinlnieius  for  the  mange,  and 
other  cutaneous  disease*.  A  decoction  of  white  hellebore  Is 
frequently  used  for  the  tmxna  pur|>ose ;  but  other  medicines  are 
l^-iicrally  added  lo  il ;  as  ttiJphur  vivvm,  tuqienline,  white  vitriol, 
or  alum.  Hellebore  lias  been  trii-d,  ns  an  iidfrtuit  remedy,  in 
th«  small  dwe  of  halfa  drachm,  and  has  been  declared  to  be  a 
dangerous  mc<licine. 

Hourcvcr,  1  have  lately  had  an  o])portunity  of  trying  tbocHrct 
of  white  MIebore,  nnd  did  i>ot  Tind  it  to  violvni  or  so  danen^ 
ous  as  it  was  said  to  be,  after  an  exfierimont  made  lU  Uic  Ve- 
terinary College.  To  a  glandercd  horne  I  gave  half  an  ounce 
of  the  powder  of  white  helh'bore,  expecting  it  would  d»trov 
bim,  but  it  produced  no  elTect ;  an  ounce  wan  then  given,  which 
caused  an  appearance  of  sickness,  and  a  copioim  diMliargo  nf 
saliva  from  the  iiioutli.  It  was  given  afierwurdK  to  sercial 
liorscs;  nnd  was  uniformly  found  in  tlie  doae  of  half  on  ounce, 

fiven  daily,  to  produce  the  effect  above  desciibed.  In  Mime,  the 
rsl  dose  caused  un  appearance  of  sickne^  and  sidivaiiori ;  oihen 
took  several  do^es  before  any  effect  was  observed.  It  wnt  given 
duly  in  a  rase  of  farry,  in  ihc  dose  of  half  un  ounce,  nnd  the 
lioi-M.-  got  well:  no  other  remedy  was  employed  except  blisters. 
In  none  of  tlie  experiments  did  it  cause  any  dangerous  symp- 


AKD    PHJinaiACOrtEIA 


tonts,  but  it  certainly  caused  a  very  painful  seiisatioti  in  the 
stomach.  (Sec  CATitAitTics,  remarks  on.)  The  general  effect 
of  hellebore  is  nauseating,  by  which  it  lowers  the  action  of  the 
heart  very  considerably,  and  may,  therefore,  be  adraniageou-tly 
employed  in  inflnmmiitory  diseases.*  This,  however,  lias  be«a 
denied  by  some  veterinarians. 

Black  hellebore  i^  ircldom  nsed  in  horse  medicine.  Stick*  of 
black  hellebore  are  sometimes  inserted  under  the  ekin,  particu- 
larly in  cattle,  in  order  to  produce  an  issue.  [Black  hellebore

HKMLOCK.  —  Cvniiim  Maculnlum.  Tliis  is  an  indigenous 
plant,  growing  generally  in  moist  shady  places,  and  flowering 
in  .lune  and  July.  It  is  a  strong  narcotic;  but  supposed 
to  l>e,  oil  some  occasions,  an  useful  medicine,  po<ac«»iug,  like 
opium,  an  anodyne  <|ualiiy,  but  not  so  certain  in  its  cRV-ct, 
It  is  said,  however,  not  to  produce  costivenes«,  likeopium.  Tl>e 
complaint  in  which  it  has  been  chiefly  employed  in  veterinary 
practice  is  obstinate  cough,  depending  ujiou  irritability. 

The  leaves  are  to  he  carefully  dried  and  powdered.  The 
jKiwtlcr  niuM  be  kepi  in  a  well-stopped  botlle,  from  wliidi  tlie 
light  »]iould  l>e  excluded.  The  dose  is  aboni  a  drachm  ;  but  it 
may  be  gradually  increased  to  a  much  larger  quantity. 

There  is  an  extract  made  from  hemlock,  which,  wlien  ptxy 
pared,  is  a  very  convenient  form,  and  not  less  efficacious  than 
the  powder.  Tlie  dose  is  about  s  drachni ;  but  ibis  also,  may  be 
gradually  augmented  to  a  considerable  quantity. 

A  decoction  of  green  hemlock  is  said  to  be  an  useful  fo- 
mentation in  painfiil  wounds  and  tumours.  Since  writing  the 
above,  I  gave  about  half  a  pound  of  green  hemlock  to  a  young 
a»  ;  he  ate  it  readily,  but  it  did  not  proiluce  any  sensible 
effect.  It  has  been  said  that  goau  eat  hemlock,  and  are  nou- 
rished by  it. 

It  should  be  remarked  that,  as  the  powers  of  the  powder  are 
often  impaired  by  keeping,  whenever  a  fivsh  parcel  or  quantity 
of  the  lierb  is  nuf),  it  sliuuM  first  be  aduiinisleretl  in  small 
doses,  in  order  to  ti<^certaiu  Ws  strength.  Vinegar  ts  said  to  be 
the  best  antidote  for  an  over-dose  of  hemlock,  after  bleeding  and 
purging  have  been  employed.

HONEY.  —  Mel.  A  small  quantity  of  honey,  dissolved  io 
litiMwd  infusion,  is  often  used  in  those  troublesome  coughs  which 
ariM*  from  irritation,  and  serves  in  this  way  as  a  gao<l  auxiliaiy

HORSE- HADISH.  —  /irmoraeia.  The  root  of  horse-radish, 
when  fresh,  is  n  powerful  stimulant.  All  its  virtues  may  be  ex-

state  it  may  be  kept  a  long  time  without  losing  its  strength.  It 
is  said  to  possess  also  a  diuretic  and  diaphoretic  quality.  Its 
acrimony  is  destroyed  by  boiling ;  it  is  therefore  mveii  either  as 
an  infusion,  or  beaten  into  a  mass  with  flour,  asaball.  If  beaten 
into  a  mass,  and  formed  into  a  paste,  with  Hour  of  mustard  and

of  a  stimulant  to  glandular  structures,  and  the  forms  in  «i

Diniodidt  of  Copper, —  Mr.  Morton  has  formed  a  new  com-

him  snuffle  and  sneeze  fur  some  minutes ;  at  the  end  of  an  hour 
he  ap)>ears  agitated,  the  l>etly  tense,  but  the  arteries  and  flanks 
beat  with  violence  for  four  or  five  houi's :  the»e  appearances 
gradually  go  off.  Given  to  the  extent  of  three  ounces,  it  dis- 
tresses tJie  horse  greatly;  he  lies  down  and  soon  gets  up  again, 
his  flanks  lieai,  he  sighs  and  groans,  and  unless  water  be  given 
him  he  dies  convulsed.  On  these  symptoms  going  off^  his  dung 
is  a  little  softened,  but  it  does  not  purge.  I  once  gave  an  ounce 
to  a  yoimg  ass,  but  it  did  not  produce  any  perceptible  effect. 
Boui'gelat  says,  it  is  employed  in  chronic  bowel  complaints,  in 
molion  grease,  and  dysentery,  with  sucoefis,  either  as  an  infusion 
or  decoction.  He  also  observes,  that  though  it  does  not  cause 
any  sensible  evacuation  in  large  animals,  it  purges  llie  sheep;

[  is  scarcely  an  old  book  on  farriery  in  which  it  is  not  recoin- 

I  mended  for  horses  as  an  ingredient  in  purgative  balls  or  pliysic; 

I  which  practice  is  still  foDovnxl  by  farriers,  who  generally  put 

I  two  or  three  drachms  of  jalap  into  i>%'erv  dose  of  physic.     It  xm 

'  tried,  liowever,  first  at  iIh*  Veterinary  College,  and  was  found  to 

have  no  purgative  effect  on  t)io  liopfe,  though  given  in  eon- 

stderably  larger  dmes  than  even  furriers  employ;  but  I  have

JAMES'S  POWDER.  —  PaUii  Jacohi.  TIioukIi  llie  pie- 
paraiion  of  this  medicine  has  been  hitherto  kept  secret,  iliere  U 
no  reason  to  doubt  its  being  composed  chieilv  of  antimony,  and 
nearly  the  same  thing  as  that  which  ia  sold  io  the  shops  hy  the 
name  of  Antimonial  Powder,  (See  Antimony.)  1  can  venture 
Io  an^ert  that.  a»  a  horse  medicine,  this  is  as  useful  and  t-fficiiclous 
as  Jamta*  Powder.  It  is  said  to  be  an  excellent  medicine  in 
I  fevers  of  every  kind;  and,  thoufjh  usually  given  in  the  small 
tlofic  of  a  scruple,  or  half  a  drachm,  may  be  exhibited  with  per- 
I  feet  siift'ty  and  belter  effi-ct  in  a  much  larger  quantity.  I  never 
j  give  less  than  two  drachms,  and  sometimes  three ;  and  I  have 
seen  even  one  ounce  given  at  a  dose  without  the  least  incon- 
rrnionce.  It  seems  Io  act  on  the  skin  like  emetic  tartar,  and 
[)romotcs  insensible  perspiration :  hut  I  do  not  think  it  is  so  cer- 
tain in  its  effects  as  emetic  tartar;  it  is  sometimes  joined  with 
opium,  camphor,  nitre,  or  ginger,  according  to  the  nature  of 
tltc  diF^aKc:  with  ginger,  it  forms  a  good  medicine  for  horses 
tliat  arc  hide-bound ;  but  this  compound  is  not  proper  in  fevers, 
or  any  compUinl  arising  from  infhimmation,  wid  the  fevers  of 
Iwrsej  are  almost  always  inflammatory.  It  is  most  commonly 
^ven  with  nitre  or  with  nitre  and  camphor;  and  some  prac- 
I  Utionvrs  prefer  it,  as  a,  fevi.-r  medicine,  to  tartariscd  antimony 
(tartar  rmftic).  It  lias  been  asserted  that  it  is  much  improved 
w  a  diaphoreiic  In  the  human  subject,  by  (be  addition  of  one 
fiiunli  of  its  weight  of  precipitated  sulnhuret  of  antimony.  (Sec

therefore  not  be  administered  in  a  drmch.  According  to  the

oxide  is  ohlaincd  by  the  simple  action  of  heat  and  air  upon  lead. 
It  is  employed  in  making  Goulard's  extract  and  diachylon 
plaster. 

LITMUS.  This  is  a  species  of  lichen.  Litmus-pauer  is 
used  in  medicine  as  a  very  delicate  test  of  the  presence  of  ncid, 
by  which  its  blue  or  violet  colour  is  changed  to  red.  It  is 
gcnernlly  by  means  of  litmus-paper  that  the  urine  ia  tested,

LOGWOOD.  —  Hirmatiixi/li  I.iirnuni.  .\n  extract  made  from 
logwood  pos^sses  a  considerable  ujtringeni  power.  It  is  often 
employed  by  medical  practitioners  in  diarrhcea  depending  upon 
relaxation  of  the  bowels ;  an<l  tliough  it  lias  not  yet  been  intro- 
duced into  veterinary  practice,  it  would  probably  be  found  an 
useful  medicine  in  similar  complaints  of  the  horse,  and  deserves 
a  trial  in  cai-es  wliicb  have  resisted  the  common  remedies. 

It  may  be  given  in  doses  from  two  to  three  drachms.  Alum,

MALLOWS,  COMMON.  —  Malm  S^lctttri*.  This  !i  an 
annual,  indij^enous  plant,  and|  from  (he  mucilage  it  eontaiiii,  it 
useful  in  the  composition  of  emollient  drinks:  fomentation), 
clyster*,  and  poultices  may  also  be  made  with  it.  See  Emol- 
lients,  l''oMF.STATIOV9,  Bltd  Cl-ySTIlKS. 

MALT  is  very  serviceable  to  horses  that  are  recovering  from 
fever.  It  is  uselul,  also,  when  the  system  is  weakened  by  large 
absoeoses  which  discharge  copiously,  and  in  almost  every  case 
depending  on  debility. 

It  appears  to  be  easy  of  digestion,  nnd  very  nutritious,  though 
not  so  slimulaling  as  oala.  Grei.-n  mall  ha§  been  recommended 
for  improving  ihe  condition  of  horses,  and  giving  them  a  sniootb, 
glossy  coal.  Infusion  of  malt  is  soD>etimcs  given  with  advan- 
tage to  sick  liorses ;  but  they  generally  require  to  be  drenched 
with  it.  which  is  a  great  inconvenience. 

MANGANESE-  A  metallic  oxide  used  nrincipallv  in

MARJORAM. — Orii/anum,  Sweet  maijoram  is  an  annual 
ulant,  which  is  principally  cultivated  for  culinary  purposes. 
Wild  marjoram  yields  an  essential  wl  {oleKm  orifftmi),  which  it 
much  used  by  farriers  as  a  remedy  in  strains,  bruises,  S:c.,  but 
always  mixed  ivitlt  other  oils  or  spirits,  such  as  oil  of  elder, 
cuiTiphornied  spirit,  &c.  A  strong  inliision  of  marjonun 
may  be  einployerl  as  a  vehicle  lor  carminative  or  cordial  medi- 
cine. 

MARSH  MALLOW.  —  AMtea.  Tliis  plant  contains 
rather  more  mucilage  than  common  mallows,  and  is,  therefore, 
better  calcutnted  for  making  mucilaginous  or  emollient  drinks, 
clysters,  or  fomentations. 

I'he  root  is  ihc  best  part,  and,  if  carefully  dried,  may  be  kept 
a  long  time,  'riieso  mucilaginous  drinks  are  very  useful  wlien 
tlie  bowels  or  bladder  aiv  inflamed  or  irritated  by  loo  strong 
pliynie,  or  when  lliere  is  any  pain  in  the  urinary  passages.  They 
should  be  given  frequently  in  tliecourseof  the  day,and  nuty  ucca-

while  the  physic  is  operating.  In  making  mult  Riasliea,  the  water 
should  be  below  the  boiling  point,  otherwise  the  malt  will  dot 
and  be  sjwiled.  These  ore  given  for  the  purpose  of  recruiting 
strength,  when  a  horse  is  debilitate<l  from  fever,  or  any  other 
caufe.  (See  Malt  and  KKSToicATtvts.)  When  a  horse  has  been 
fed  high  for  some  time  with  oeiIs  and  beans,  a  change  to  a  diet 
of  bran  mashes  for  two  or  three  davs  will  often  do  a  great  deal 
of  good.  The  bran  should  be  fresii,  and  perfectly  free  from  any 
unpleasant  or  musty  smell.  There  is  a  liner  kind  of  bran, 
named  gurglings  or'pollard,  which,  though  much  more  nutri- 
tious, is  not  so  fit  for  medicinal  purposes. 

MEADOW  S.VFFRON. —  Co/rJ((«Hi.  Auhimitale.  This  is 
an  indigenous  perennial  plant,  generally  found  growing  in  rich

diuretic  in  the  human  system,  but  its  elTect  on  the  horse  is  not 
known.  An  account  was  published  in  the  New  Monthly  Maga-

sesses acooling  and  diuretic  property,  which  renders  it  ex tremel;~ 
useful  in  fevers,  and  all  inflammatory  complaints. 

In  fe%-prs,  it  is  often  joined  with  emetic  tartar  and  digital 
with  good  effl-ct.     In  calurrh,  or  cold,  nitre  is  a  useful  remedy; 
and  in  trotiblcsomc  coughs  it  often  gives  relief. 

The  usual  do«c  of  nitre  is  about  one  ounce,  tliou^i  farrien 
often  give  double  that  quantity,  or  more:  but  in  such  largo 
docGS  it  is  apt  to  irritate  the  stomach,  and  do  mischief;  theiv- 
fore,  in  uruent  cases,  half  an  ounce  may  bo  given  every  iburth 
liour,  in  wnieh  way  iliere  will  be  Ins  danger  of  its  producing 
tliat  elTecl,  particularly  if  it  be  given  in  a  mucilaginous  drink, 
or  in  water  gruel.*  II  nitre  be  given  in  the  form  of  »  ball,  it  ia 
adviscable  to  otFiT  some  water  immediately  before  or  a^er,  or  to

OPIUM.     The  inK[iisiiatc<l  Juice  of  the  White  Poppy. 

This  is  one  of  the  most  important  articles  of  the  Materia 
Medica. 

It  is  classed  among  the  narcotic  leciatives,  of  which  it  is  un- 
doubtedly the  most  useful. 

Opium  is  broiij;ht  to  this  country  in  chests  from  Turkey  and 
India.  Thi!  Turkey  opium  is  in  tint  pieces,  covered  with  leaves 
and  the  reddiih  cjipsult^  of  some  tiptvirs  of  dock,  whii-h  is  con- 
sidered an  indication  of  ila  goodiieits,  ns  tiie  inferior  kinds  of 
opium  hare  none  of  these  capsules  adhering  to  ilietn.  Turkey 
opium  generally  contains  about  one  fourth  |>arc  of  impurities. 
Indian  opium  is  less  pure;  is  in  round  masse*,  covered  with 
leaves  to  the  thickness  nearly  of  one  fourth  of  an  inch.  Mr. 
Kerr  relates  that,  at  Iluhur,  it  is  fre<)uently  adult<'nite(l  witli 
cow-dung,  the  extract  of  the  poppy  procured  by  boiling,  and 
various  otiier  substances.  It  is  mode  also  from  lettuces  in 
India. 

In  Malava  it  is  mixed  with  oil  of  iteHinium,  which  is  o(^v\

In  HatuleDCV  or  epasm  of  the  bowels  it  is  an  excellent  remedy, 
(narticularly  if  joined  with  aromatic  powdor,  ginger,  or  Mxnc 
other  stimulant.  In  diarrhora  it  is  an  effectual  remedy,  but 
must  be  given  cautiously.  In  diabpie»  I  have  fotind  it  very  b<y

Opium  is  Very  apt  to  pnxluc*-  c<Mlivenr««  in  horws;  but  this 
tendency  may  be  in  a  great  miiuiire  counteracted  by  excrci*e; 
when  it  does  take  place,  it  may  be  removed  by  dystvrs,  hna 
maslK-s,  or  a  laxative  ball.

effi-ci,  two  drochniH  will  nut  be  too  much. 

The  diseases  of  the  hor»e,  in  which  o]>ium  ix  most  beneficial, 
are  locked-jaw  and  flatulent  colic;  in  the  former  it  has  hern 
given  in  larije  doso,  with  tin-  be»l  effect,  generally  joined  widi 
camphor,  and  so[neiiiiH<s  with  assafcctida  and  other  antispu- 
inodics.  In  flatulent  coUc  smaller  doses  have  bet'n  found  suit*

ture, prepared  according  to  tlitr  London  Diipcn.iiilory,  is  one 
ouiKje,  and  of  nolid  opium,  purified,  a  draclim.  Half  an  ounce  of 
purified  opium,  according  to  Hoardman,  was  given  to  a  Itorse  at 
one  do^ ;  he  slept  through  the  daytime  for  eight  or  nine  houn, 
and  could  not  he  easily  roused.  In  locked-jaw,  tlie  santc  author 
nrescril>es  three  drachms  of  purified  opium  eveir  tlirev  or  four 
hours,  with  camphor  and  salt  of  hartshorn,  of  each  half  an 
ounre.  But  Mr.  Wilkinson,  who  hjis  succeeded  in  twenty-four 
ca:*es  of  locked-jaw,  gave  only  one  drachm  of  common  opium,  with 
the  same  quantity  of  camphor  and  as»afcelida :  but  he  gradually 
increased  the  dose,  and  went,  in  some  cases,  so  far  as  lo  iwo  or 
three  dnichms.*  In  the  human  body  opium  is  sonietimes  rm*

AND    PHAKMACOFCEIA.  517. 

'  tuH  opium  iu  the  form  of  a  spirituous  tincture,  as  kept  in  the 
aliopt,  in  preference  to  the  watery  soluiion  or  mixture';  tlii-rc 
ra«v  be  cases,  however,  in  which  ihc  spirit  may  be  improper, 
and  then  the  watery  mixture  should  be  preferred.  Opium  is 
decxMiipo^rcl  by  ammoniii,  potash,  and  ^oda,  and  their  »ub-oiir- 
bonntea,  morphia  being  precipitated,  uUo  by  most  metallic  i&\i» 
and  infuuon  of  gall*;  such  combinations  should  thererore  be 
avoided:  but,  in  combination  with  vinegar,  the  vegetable  acids, 
and  oil,  in  strength  or  narcvtic  power  is  said  to  be  ratlier  in- 
creaaed,  being  thoroughly  extracted. 

The  mode  of  purifying  opium,  prescribed  in  the  London  Dis- 
pensatorv,  is  to  dissolve  it  in  proof  spirit,  then  filter  the  solu- 
tion, and  evaporate  in  a  water  balli  to  the  required  convi'tience ; 
but  u  more  ready  way,  though  not  so  elfeclual,  is  to  dry  il  carc^ 
fully  by  a  moderate  heat,  powder  and  sift  it.  The  »ievf  will 
keep  back  many  of  the-  impurities,  when  this  is  carefully  dune. 
Opium  is  an  article  of  so  much  importance,  that  it  appeared 
necessary  to  notice  it  particularly,  and  at  some  length.  I'here 
is  a  vinous  tincture  of  opium  sometimes  used  in  diseases  of  the 
human  eye.  I  have  found  !t  very  useful  in  chronic  tnf1amn)a- 
(ion  of  the  horse'ti  eye,  applied  undiluted.  If,  however,  ten 
parte  of  distilled  water  be  added  to  six  parts  of  tincture  of 
opium,  the  strength  of  wine  of  opium  will  he  (ibtuined,  and  the 
mixture  will  be  appiicnble  for  the  same  purpose*  in  the  horse. 

[Opium  contains  two  peculiar  vegetable  compounds,  in  which 
its  power  resides:  one  of  these  is  an  alkaline  tiubsiance,  called 
morphia ;  the  other  does  nut  possess  similar  chemical  properties, 
and  has  received  the  name  of  narcotine.  Morphia  exists  in 
opium,  in  combination  with  a  peculiar  acid,  called  the  nieconic 
acid ;  and  the  salt  is  termed  meconate  of  inorpliia.  The  acid 
has  no  narcotic  power. 

Morphia  may  also  be  obtained  by  adding  a  solution  of  am- 
monia to  one  of  opium  in  acetic  acid;  the  acetate  of  morphia 
formed  is  decomposed,  and  the  morphia  is  immediately  precipi- 
tated of  a  brownish  colour,  which  may  be  removed  by  boiling  in 
water  with  animal  charcoaL 

Although  it  seems  sufficiently  proved  that  morphia  possesses 

the  characteristic  properties  of  opium,  yet  its  strength   is  not 

commensurate  with  its  apparent  concentration  ;  and,  when  un- 

combined,   it  exerts  but   little  action,  in   consequence   of  its 

^^ptolubility.

mineral,  vegetable,  and  animal.  Of  the  first  kind  arc  arsenic, 
corrosive  sublimate,  and  certain  preparations  of  lead.  Tlie  best 
antidotes  to  arsenic  are  oily  and  mucilagltioiis  liquids,  sulphate 
of  potash,  BOiip,  and  cafilor  oil  in  a  sohition  of  sulphate  of  mag-

tlie  yew  plant  with  twice  as  much  uati  did  not  kill  or  produce 
any  lemilile  inconvenience:  and  the  »ame  rciull  took  place  iti 
three  or  four  experinienis  of  Professor  Viborg.  A  larmcr  near 
Exeter  lost  several  cows,  by  eating  the  leaves  of  some  yew  trees 
which  grew  in  the  hedge  of  the  field  where  they  were  kept.  'I'he 
following  circumstance,  also,  was  related  in  Woolmer's  Exeter 
Paper:  •'  A  yew  tree  having  been  felled  in  a  field  at  Warley, 
Somerset,  belonging  to  Fanner  Iliscox,  in  the  course  of  the 
emuing  night,  six  out  of  seven  cow^  (hat  were  with  calf,  died  in 
conaequence  of  eating  its  branches."  We  know  of  no  antidote  to 
this  poison,  but  we  can  certainly  prevent  our  cattle  from  eating  it- 
Common  Hendock  is  said  to  be  poisonous,  but  I  have  given 
eight  ounces  to  a  young  nss,  which  he  ate  readily,  and  suffered  no 
inconvenience  from  it.  I  once  gave  two  drachms  of  Stavesacre  to 
a  glandered  horse  ;  he  died  in  great  pain  the  following  night.  * 
It  ia  probable  lh<it  more  horses  have  been  killed  by  aloes  than  by 
any  other  vegetable  prq)aration  ;  that  is  to  say,  by  strong  physic, 
or  by  neglecting  tlie  horse  during  its  operation.  The  unimal

that  the  anodyne  or  narcotic  qualities  of  opium  are  diminished 
by  long  boiling,  and  that  the  extract  of  poppies,  however  care-

POTASH.  —  J'otatsa.  (New  name,  Piiotoxide  or  Porxsr 
BiUM.)  There  is  a  great  variety  of  preparations  of  potassa  used 
in  medicine,  as  the  liijuor  pota»ta^  or  soKition  of  potassa,  whicli 
is  diuretic  and  antacid ;  the  jfotasta  /Ufa,  or  fttsed  poiassa,  a 
caustic  deliquescent  salt;  the  pobuta  cum  calee,  or  potaau  witli 
lime,  a  mildiT  c«u!'tic;  the  ptdcwas  bilartrtUf  or  bilartrate  of 
|M>tnMa.  With  xulphurie  acid  it  forms  vitriotaied  tJtrtar,  or  m1 
pulychrett  {SuJfiAate  of  Potat/t) ;  with  nitrous  scid,  tlint  very 
useful  medicine  termed  niire {Sitrate of  Poia$h),  which,  contrary 
to  what  we  have  just  observed,  is  a  diuretic  in  a  moderate  dose 
(see  Nitre);  and  with  vinegar,  or  acetous  acid,  it  makes  so- 
luble tartar  {Tartariatd  Potanh).  Th«-  pearliuih  of  commerce  is 
the  carbonoie  of  potnsb,  and  is  in  a  very  impure  state,  and  not 
applicable  to  chemical  or  medical  purposes.  When  sufficiently 
purified,  it  is  joined  with  diuretics,  purgatives,  and  tonics,  with 
advantage.  In  i)io!te  cases  which  require  tlic  use  of  tonics  iliere 
is  sometimes  an  acidity  in  the  stomach,  which  potash  corrects; 
and  it  renders  purgative  medicines  more  easy  of  solution. 
Given  alone  it  acts  as  a  diuretic.  When  neutralised  witK  acids, 
it  has  a  laxative  property,  but  requires  to  be  given  in  targe 
doses.  The  purified  potash  is  named  in  the  shops  Snh-tarioHoU 
of  Pultnli ;  formerly  called  Sail  of  Tarlnr,  or  l*re(Kired  Kali,  or 
Salt  of  Wormwood.  When  iwtash  is  deprived  of  tlw  carbonic

POULTICE,  or  CATAPLASM:  of  LINSEED;  of 
BEER-GROUNDS;  of  C.MXROT.—  Cataphsma  ;  Lim  : 
Certitisia  ;  Dauci.  Cataplasms  are  useful  applications  for  pro- 
moling  suppuration  in  inflamed  tumoiirBi  and  in  those  diseases 
of  the  horse's  heels,  named  grease,  scratches,  cracks,  &c..  con- 
ustin^  in  inflamed  sweUiiigtt  nf  the  heeU,  felid  discliEirgr,  painful 
and  troublesome  ulcers,  or  cracks  generally  under  the  fetlock  or 
bend  of  the  heel.  The  poultices  commonly  employed  on  those 
occiuions  are  of  the  emollient  kind. 

KMOLLIENT    POULTICE, 

No.  L  Linseed  meal ^  lb. 

Bran 2  quarts. 

Hog's  lard  , 4  ounces. 

Boiling  water  enough  to  make  a  soft  poultice.* 

No.  S.  'J'urnips,  thoroughly  boiled  ntid  mashed ;  any  quan- 
tily.     Lin«Ofd  meal  enough  to  form  llie  poultice. 

A  poultice  made  of  carrot,  grated  very  fine,  is  detergent  and 
BlJmulaling. 

Either  of  these  simple  poultices  may  be  converted  into  an 
anodyne  i>oullice  by  the  addition  of  opiiim ;  ituo  a  fermenting 
poultice,  by  the  addition  of  yeast,  <uid  by  »ub«titnting  oatmi-al 
for  linseed  meat ;  into  an  astringent  potillic<',  by  the  addition  of 
Goulard's  Extract,  sugar  of  lead,  or  jiowdered  alum ;  and  into 
a  detergent  poultice,  by  tlie  addition  of  white  or  blue  vitriol. 

In  obstinate  cases  of  virulent  grease,  where  there  is  much 
pain,  and  a  stinking  dnrk-coloured  discharge,  and  especially 
when  emollients  are  found  ineffectual,  the  detergent  poultice  has 
quickly  cured  the  disease :  and,  in  such  eases,  even  a  solution  of 
corrosive  sublimate  has  been  used  with  the  best  effect.  But 
emollients  should  always  be  first  fairly  tried,  and  eome  diuretic 
medicine  given. 

For  poulticing  the  foot,  a  leathern  boot  affords  the  most  suit- 
able method,  as  a  hag  or  a  siocking  will  be  soon  worn  through 
by  the  edge  of  the  crusl.  A  stocking,  however,  with  the  fool 
part  cut  off,  affords  a  convenient  mode  of  applying  a  poultiov 
to  the  knee  or  leg. 

POWDERS.  —  Puhvrei.  These  are  sometimes  coiirenient

ROSEMARY.  —  Rogmarintu  officinaHs.  This  plant  is  cul-

ho1«  is  made  in  tho  centie  about  halfan  inch  in  diampter;  it  is 
(hen  covered  wiih  tow  (ihe  hole  being  left  ojica),  .ind  Miwared 
with  digestive  oiniment :  when  (he  rowel  is  put  in,  the  hole  in 
the  middle  of  the  leather  ia  plugged  up  with  »  little  tow. 

In  this  situation  it  is  left  until  matter  forms,  which  generally 
happens  in  three  oi-  four  days;  the  plug  nf  mw  h  then  with- 
drawn, the  rowel  moved,  and  the  matter  suflwed  to  How  out,  in 
which  Biate  it  remaina  as  lonfj  as  is  thought  necessary.  Thus 
we  see  that  a  rowel  is  an  ariiliciat  isaiie  or  abscrM.  the  leather 
first  cansiiig  inflammation,  wbich  ends  in  suppuration  or  the 
fbrmaiion  of  mailer;  and  the  matter  continuing  lo  be  Ibrmed  so 
long  as  the  extranc-ous  body  ov  leather  remains  under  the  skin. 
The  rowel  must  be  moved  every  dav. 

Tlie  intention  of  rowclling  is  to  divert  inflammalton  from  any 
important  organ  or  part  of  the  body.  Thus,  when  the  lungs 
are  inflamed,  the  animal  certainly  dies,  unless  it  is  put  a  stop 
to;  but  the  skin  may  be  inflamed  to  a  considerable  extent  with- 
out danger  ;  wc  therefore  put  a  rowel  in  the  chest,  which,  though 
not  sufficient  of  iuelf  to  stop  the  inflammation  of  the  lungs,  con- 
tributes materially  to  this  purpose,  and,  with  the  other  necessary 
remedies,  often  effects  a  cure.  In  large  swellings  of  ihe  hintl 
]*g^  and  obstinate  cases  of  grease,  rowels  in  the  thighs  are  good 
remedies. 

In  shoulder-strains,  a  rowel  may  sometimes  be  put  in  tlte  chest 
with  good  effect.  In  short,  when  inflammation  attacks  an  easeri- 
ti»l  and  important  part  of  the  system,  much  lieiu-fit  will  often  l)e 
derived  fmm  inserting  a  rowel  in  some  contiguous  part  that  is  of 
little  importance.  When  a  rowel  is  removed,  the  part  generally 
heals  of  itself;  if  not  a  little  Friar's  balsam  may  be  applied. 

Many  practitioners  consider  blistering  the  sides  extensively  as 
a  more  effectual  means  of  diverting  inflammation  from  the  lungs 
than  rowels;  and  1  am  inclined  to  think  they  are  right.  The 
rowel  is  sometimes  smeared  with  blistering  instead  of  digestive 
oiniment :  hut  there  is  danger  of  the  cantharides  being  absorbed 
and  causing  inflammation  of  the  kidneys.  I  have  known  a 
horse  destroyed  in  this  way.  In  cases  of  very  severe  internal  in- 
flammation, very  little  can  l>e  accomplishetl  either  by  rowels 
or  blisters. 

Whenever  it  is  thought  necessary  to  make  the  oiniment  which 
is  used  in  rowelling  more  siimiiialing,  it  may  be  easily  done  by 
adding  oil  of  turpentine  to  it.

SQUILL,  or  SEA  ONION.  — ««;/«  Marilima.  This 
ii  a  native  of  Sicily,  Syria,  Barbary,  and  Spain.  The  bulb 
ii  extremely  lar^e,  and  h  in  one  variety  white,  in  anoilier 
reddish.  It  is  itwdoroua,  bitter,  and  acrid.  The  best  prepara- 
tion of  squill  for  veterinary  purposes  is  the  powder  of  the  dri«d 
root,  which,  in  tlie  dose  of  one  drachm  or  more,  n  considered  a 
good  expectorant,  and  useful  in  chronic  cough:  in  larger  doses 
it  generally  iu:t)  as  a  diuretic,  but  is  noi  a  desirable  mHliriiic 
for  that  purpose,  there  being  many  diuretic^  more  cerlain  in 
llteir  i-fiV'ct.  Gum  amnnmiaeum  is  an  elij^ible  addition  to  sipiill ; 
and  I  have  sometimes  seen  camphor  and  opium  joined  to  it  wjih 
good  effect.  One  drachm  of  ibe  dried  squill  is  equal  to  about 
five  drachms  in  its  fresh  stale.  There  aie  three  other  prepara- 
tions of  squill  made,  viz.  the  spirituous  and  acetous  tincture,  and 
the  oxyme) ;  but  these  are  not  so  well  calculated  for  veterinary 
purposes.     See  Esi'Ectouants. 

STARCH.  —  Triticiun  hubemum.  Starch  glysters  with 
opium  are  sometimes  employed  in  obstinate  dlarrlnen  or  irritation 
of  the  rectum.  In  no  other  way  is  starch  useful  in  veierinnry 
practice,  while  the  cheaper  mucilages,  such  as  linseed,  marvh- 
mallow,  &c.  can  be  procured;  but  wlien  these  arc  waiitinj^,  it 
IK  capable  of  making  a  good  mucilaginou*  drink.     See  KmoL' 

LICNTS    nnd     DtMULCENIS. 

The  preparation  named  Arratc-root  Is  a  pure  starch,  and  when 
Ic  into  gruel  is  the  best  and  safest  preparation  that  can  l>e 
employed  In  diarrhoea,  or  to  restrain  the  effect  of  purging  medi- 
cine when  it  has  been  given  too  largely.  Mixed  with  a  watery

STYPTICS  arc  medicine:!  which  constringe  the  blood-veucis 
when  woniuU*d,  *o  as  to  Kiop  an  elFusion  of  ulood.  Many  pre- 
parationA  have  bet-n  recommended  for  this  purpose:  but  when 
the  size  of  the  woniided  vessel  is  at  nil  considerable,  an  adec|UiiIe 
degree  of  pressure  by  means  of  bolsters  and  bandages  should 
rather  be  depended  upon ;  and  wlien  thai  cannot  be  done,  the 
vessel  must  be  tied  up  above  the  wound  and  1>elow,  by  which  the 
bleeding  will  be  etfectuaily  suppressed.  No  danger  is  to  be  ap- 
prehended from  slight  bleedings  in  tlie  horse,  as  they  always 
cease  spontaneously. 

The  styptics  commonly  employed  are  oil  of  turpentine^  di-

gave  an  ounce  of  sublimate  in  a  mucilaginous  decoction,  to  a  colt 
of  one  y^iRr  old  affected  with  fan^'.  He  increased  the  dose  of 
sublimate  until  it  amounted  to  S  ounces,  3  drachms,  21  ^rainii

I  have  given  sulphur  in  a  vjiriety  of  doses;  but  the  otdy  effect  [ 
coidd  perceive  nas  that  of  a  mild  laxative,  and  tliat  did  not  take 
place  until  four  ounces  were  given  al  a  dose.  From  (he  observ- 
ations 1  made  on  this  occasion,  1  do  not  conceive  thai  svl/i/mr 
IB  of  much  use  as  an  internal  remedy  in  the  horse,  nor  that  it 
possetees  any  diaphoretic  power.  As  a  topical  application  in

other  remedies.     See  article  Manoe.

vV  few  years  ago,  M.  Collaliie,  Professor  of  the  Royal  Veteri- 
nary School  of  Milan,  published  an  aceotmt  of  some  suece^ful 
experiments  he  made  on  glanders.  'I'he  medicine  he  employed 
was  sulphur,  beginning  with  a  dose  of  four  ounces,  and  increasing 
it  gradually  until  he  gave  two  pounds  daily,  mixed  into  an  elec- 
tuary with  honey  ;  he  also  took  away  about  two  quarts  of  blood 
once  In  two  or  ihiTe  davs.  A  dose  of  si\  ounces  caused  purging; 
ten  or  twelve  ounces  griping  pains  and  purging.  Six  ounces  of 
suipliHr  oiritm  were  then  given,  wlilch  produc-il  a  i^imllar  eflecti 
and  some  of  ilie  hoi'ses  became  so  exceedingly  vivnk  that  they 
lay  down,  and  were  unable  to  rise  for  ilirrc  or  four  days.  When 
diey  recovered  a  little  from  these  alarming  syinpionis,  he  found 
the  discharge  from  the  nostrils  much  U-s<ened,  afi  well  a*  tlie 
swelling  under  the  jaws.  In  some,  llie  dispase  entirely  diaap- 
pearcd,  but  after  a  lew  days  returned,  and  was  not  pcnuttnvndy 
curt^d  till  it  had  fluctuated  in  this  way  several  time*.  Af[Cr  they 
had  got  over  the  elfcct  of  the  sulphur,  on  giving  it  ngain  he 
found  that  a  dose  even  of  twelve  ounces  produced  no  effect;  he 
therefore  htcreosed  il  to  eightei-n  ounces,  and  from  that  10 
iweniy-four  ounces:  but  It  no  longer  caused  either  purging  or 

Sriping.  Having  continued  the  me  of  the  nieilicine  in  thi*  large 
see  for  some  lime,  and  Hnding  the  dliieaKe  remain  stationary  in 
some  of  the  horses,  he  discontinued  it  for  eight  or  ten  days,  in 
order  lo  restore  the  susceptibility  of  the  animal  to  the  action  of 
sulphur.  On  rt-coinmenclng  the  ireainicnt,  he  joined  to  six

While  lite  hiirKe  is  taking  tunics,  j^i-eat  iitlfiiliun  i^iould  be  paid

to  assert,  that  by  judicious  management  with  regnixl  lo  1o(k), 
Brooming,  aiid  exercise,  and  the  occasional  use  of  mild  plmid 
horses  would  seldom  require  tonic  medicine. 

Tonics  may  be  divitfed  into  minerals  and  vegetables;  the 
former  are  generally  considered  llie  most  powerful,  and,  1 
believe,  are  ai  this  lime  generally  prefen-ed,  not  only  on  account 
of  tlieir  supposed  superior  efficacy,  but  likewiw,  probably,  from 
their  being  less  ex|K>nBive,  and  the  dose  less  bulky  and  incon- 
venient. 

In  llie  foniier  editions  of  this  work,  I  have  generally  given 
ihem  a  preferenn*,  btit  lubtcquent  experience  and  reflircliun 
have  le<i  me  to  employ  lliem  with  more  caution,  and  with  letJt 
ronlidence  in  ilielr  reputed  innoxious  qualities;  for,  nutwilti- 
siAnding  the  immense  do^es  of  arsenic,  and  blue  vitriol  (aulphnii- 
of  copper),  that  have  l)een  given  without  producing  any  imme- 
diate ill  effect,  it  is  liighlv  probable  that  the  siomacn  Euners  ma- 
terially, especially  when  the  use  of  such  medicines  is  persisted  in. 
I  have  examined  a  horse's  stomach  that  had  bcvn  inking  these 
mineral  tonics,  and  thought  ihcy  liad  not  diminished  the  animal's 
appetite  or  altered  his  api>eai'ance  ;  on  the  contrary,  he  was  in 
high  condition,  and  did  hia  work  well,  yet,  bcinj{  glandered,  was 
destroyed.  The  slomacb,  however,  had  been  greatly  injui-ed, 
and  would,  no  doubt,  had  ihe  animal  lived  ntucb  longer,  liave 
produced  some  senous  disorder. 

This  question  naturally  arises: — In  what  respects  are  those

Hy  distillaiiui)  wc  obtain  t)ie  oil,  or,  as  it  is  sometimes  termed, 
thv  spirit  of  turpentine,  a  incdicilic  of  great  utility.  In  doai-s 
of  two,  ihrer,  or  fonr  ounces,  it  fretiueiitly  cures  the  flatulent 
colic,  or  ]{riprs;  and,  when  combined  with  camphor  aud  other 
Ktinuilant^  tnitkes  a  f{ood  onibrocaiion  for  indurated  swellings,

Ibrinx  an  embrocation  llinl  has  been  found  serviceable  in  coun-

Htiuate  ulcer*  with  good  eftV-ct.  It  is  an  useful  ingredient  iri 
blistering- ointment,  and  lininionlM. 

It  is  nlso  if  prujK'rly  mnnaKed,  the  moKE  efficacious  medictno 
ittat  can  be  tiniployed  for  expt-llin^^  worms  from  the  bowels.  In

bowels  arc  previously  relaxed  by  bran  ma-ities,  or  ii  sinidl  dose  of 
aloes.  In  snial)  dosea  it  iit  a  powerful  diuretic.  Mr.  Coleman 
considered  it  almost  a  speciHc  in  flatulent  colic  in  a  dose  of  four 
ounces,  mixed  with  (j;ruel.  It  has  been  given  to  the  extent  of  eight 
ounces  at  a  dose,  without  injury  ;  but  m  one  case  a  dose  of  four 
ounces  produced  a  fatal  inflammation  of  the  etomncb and  bowels: 
in  thb  case,  however,  a  dose  of  physic  had  been  giv»n  the  day 
beforehand  the  horse  had  a  considerabte  poi'ifint^  ui  the  lime  the 
turpentine  was  exhibited.  In  the  hnm;in  body  two  druchniK  of 
oil  of  lurpenlinc  may  no  excite  the  kidney*  nn  to  produce  bloody

and  purge  vriiliout  atfeciina;  the  urinan,'  organs,  or  only  in  a 
moderate  degree.  It  is  said^o  be  almost  a  specific  remedy  for

Dr.  Latham  considers  it  a  valuable  tnediciue  in  epilepsy.  A* 
a  veu-rtniiry  nu-dicine  it  is  cei-tainly  of  great  value ;  and  though 
in  H  few  ctUK-is  when  given  internally,  it  has  produced  violent 
elTects,  merely,  I  believe,  from  bad  manaxemeni,  yet  when  judi- 
ciously administered,  it  may  be  employed  in  a  dose  of  four  ounces, 
with  advantage  and  safely.

tvhi<-h  {>ror4>a  injurious  to  thr  stomach.  In  (Icc))  vi-\U  rhc-  water 
ta  gvtie-raliy  about  the  same  iciiipcrnturc,  both  in  wiiiUT  and 
summer,  that  is,  about  40^  of  Fahivnhcii'ii  tlH'rmiHncttT.  If  u 
horse,  therefore,  in  a  hot  sumnirr  day*  ofler  being  heated  hy 
exercise,  should  drink  freely  of  such  com pantli rely  cold  water,  it 
would  probably  do  him  a  serious  injury;  for  t)K>  water  of  pondi 
or  runnin};  streams  may  at  that  tinw  l)e  fifteen  degrees  wmriner. 
In  winU-r,  however,  the  wuirr  of  deep  welU  is  generally  to  be 
pi-efcrmi,  beirif;  eonxidi-rably  wnrnier  than  that  of  ponds  or 
streama.  A«  to  the  small  quantity  of  Milpliate  of  lime  tliat  hard 
wal4'r  may  contain,  ii  is  not  probable  that  il  contributea  in  any 
degree  to  the  formation  of  atones  either  in  the  bowels  or  bladder. 
It  is  certain,  however,  that  tlie  temperaiui'e  of  water,  the  qiian- 
liiy  taken  at  a  time,  ilie  stale  of  the  body  when  taken,  and 
(.■specially  the  state  of  ll>e  stomach,  arc  circumstances  that  ought 
to  Ik-  carefully  ailcndcil  to.  The  practice  of  medicating  water, 
that  i*,  of  mixiii;;  nitre,  salts,  ;kc.  with  it,  may  be  proper  when 
hones  require  only  a  mocLerale  quantity  of  water;  but  when 
dilution  is  coitsidenrd  necessary,  their  water  elioukl  be  as  free 
IVoni  ta-Hte  or  «iim'II  bx  poMiblc. 

Horses  inidcr  the  operation  of  cathartic  medicine,  or  physic, 
siiiH'limes  refuse  warm  water,  often  because  il  is  loo  warm,  or 
of  an  unpleasant  or  »moky  smell  or  taste;  in  such  cases  it  should 
Im-  offeri-d  a  little  colder,  aiKl  free  from  any  offinisive  smell. 
Horses  are  often  watered  only  twice  a  day,  and  tlion  suffered  lo 
drink  m  much  as  they  liavc  an  inclinstioi)  for;  this  is  pariicu- 
l.irly  injuriims  to  such  as  liarv  voracious  appetite*,  or  worms, 
chronic  couiich,  imperfect  or  broken  wind.  Sucli  horses  should 
liavc  a  small  or  moderate  qtiaiitily  three  or  four  time*  a  day, 
and  their  hay  and  corn  ahoidd  be  moistened ;  this  would 
rlimini«ti  their  ap|K'tile  for  water,  which  is  generally  inordinate; 
and  if  they  are  allowed  to  drink  much,  they  are  tlie  more  iu- 
cHucd  to  Mil  immorkTately  ofhay,  if  they  are  restrained  in  whieh

WINK. —  /'tMum.  In  Krencli  buoka  on  K<rriCTV,  wine  is 
generally  recommended,  not  only  alone,  but  as  a  vdiicle  for 
other  cordials.  Thiv  proI>nbly  lias  led  tome  furriers  of  ihis 
country  to  preitcribo  port  wine  in  )il>era]  doai'r*,  both  to  borseti 
and  cattle.  There  i*  a  ^reiit  diHerence,  Iiowfver,  both  in  the 
quality  or  9tren{flli,  as  well  as  in  the  price  of  pnri,  and  the 
French  winea;  and  it  iii  not  probable  that  the  best  French  wines 
arc  ever  given  to  horses  or  cattle.  The  port  wine  of  this  country 
contains  a  Uirae  proportion  of  alcohol  (see  Alcohol),  no  leu 
indeed,  according  to  Mr.  Brande,  in  some  specimens  he  ex- 
amined, than  25  per  cent.  That  is  to  sav,  taking  the  alcohol 
natiirDlly  contained  in  the  wine,  or  rather  the  {|uanilty  produced 
by  the  fermentation  of  tlie  juice  of  the  grape,  with  the  brandy 
added  to  it  previous  lo  exportation,  it  amounts  to  one-fourth 
part  of  alcohol,  or  one-half  of  proof  spirit;  Uil,  when  the  wine 
is  of  sufficient  age,  the  spirit  is  so  intimately  blended  with  the 
other  constituent  parts,  that  the  strength  of  the  liquor  is  not 
manifest  to  the  taste.  The  French  wiue  commonly  employed 
for  horses  and  eattle  is  not  stron};er,  perhaps,  lliuri  our  cider. 
Jn  M,  Voipi's  veterinary  work,  which  I  have  before  spoken  of 
(wc  Ktiiioi>*s  Minkral),  he  directs  no  l<-ss  ilian  two  or  three 
botlk«  of  generous  wine  to  be  given  at  one  dose,  in  n  disease  he 
{enH*^nvf  prrnirieujf.  With  regard  to  wine  in  this  country,  I 
know  of  no  discuse  in  which  it  is  really  necessary;  as  a  Utile 
warm  beer  and  ginger,  or  diluted  brandy,  will  effect  every  thing 
that  can  be  accomj>lij>hed  by  wine,  A  bottle  of  port  has  been 
occasionally  given  with  good  effect  after  severe  exliaustion  from 
hunting.

ZINC — Zimmx.  A  metallic  eubtunce,  or  nther  a  M>ini- 
metal,  the  oxide  of  which  is  named  Fbmieri  of  Zinc  {which  see). 
It  affords  other  medicinal  preparations,  the  most  useful  of  which 
is  sulphate  of  zinc,  or  white  vitriol.  This  is  employed  in  making 
astringent  lotions  and  eye  waters,  and  is  sometimes  siven  inter- 
nally as  a  tonic.  See  Eye-water,  Astrinoemts,  '^micb,  and
