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

To llieae we may add the writings of Vatc!, Renault, Orognier,
Moirond, Dopoy, Bernard, and Bouti-y, bi-sidea two veterinary

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.

well worthy the latter days of this veteran in literature.

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-
ruiMC, with xueli ii vlicjc, [lie Ik-vIm are comlanity wearing, while
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,"
In the year 1702, the Vtlerinary College was eslablished, and
hL Sainibe), a French veterinarian, was appointed Profe««or.
I^I« died about a year after. Saiiitbel was the person who disco-
vered that glanders may be conimuniculed thrnu}(li ttie medium
of tlie stomach. A few years after Ins iWth, a quarto volume
a|)]>esred on veterinary subjects with hU name to it, but it con-
tained nothing of importance. The Piofessorsliip of the Ojllege
was aAerwardi liUed by Mr.Coleman and Mr. Mon-crofi, jointly;
but the latter soon gave it up for a more lucrative situation, a* •
firivatc practitioner in Oxford .Stix-el, in which be acquired the
ligheet reputation. In 1807, he was Induced (o go out lo India,

Economy of the Horse's Foot and Shoeing, by ilr. Freeman, a
gentleman much celebrated for his knowledgn of horsemanEliip,
on which hi> afterwards publislMxl a large treatise. Tlie former
work contains some good platen of tlic difTcrent parts of the
horse's foot. Abonl tlw year 1800, Mr. Colomim piiblishod hi*
splendid work on llic Siriictiiro, F-conomy, and l)iM-»«rs of the
Horse's Foot, and Slioeing. 'Ilii* work contnint-d many bcnti-
tiful and accurate plntt^ of the hoiw's foot- 'rh<:r»- afterwards
appoared otie volume of Voierinarv l'raii«acti»n», and a pnin-
phiet, dtwcribing an artificial frog, by the lame author. Aliout
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
merit, and has been »inc« piiblislKtl in one octavo volume. Mr.
Blaine's work fint appeartil in IH02 atvd I6CK), in two vohinu-s
octavo. It has sino; iH-c-n publiilted, however, in one octavo
volumo. It is the only regular syMem of veterinary medicine
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.
Ciater's *' Kvery Man his own Farrier" had Ix-en published some
years before ; and about thi* jxTiod a])peare<l his vuhmic '^ on the
Disetiaos of Caltlv." A (guarto bonk on Cattle Medicine was
publi»hed soon after by Mr. Skerrvlt, which contained some
good rcpreaen tat tons of the calf in ulero, and Rome useful ob-
servations on ihesuhjeet. Itut one of the best books thai have
ever upiteared on caitle medicine was by Mr. John Lawrence.

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.

oxpeclvd that the whole will be soon rebuilt. An old herma-
phrodite hor^ is shown here in which the male form seems lo
predominale ; of nhichi Mr. Si-wdl considers it a malfoimation.
The im|)eriai stable is a fine spacious building, tlooied with
wood, well di-ained, and vcniiluic-d, and cupabiu of accommo-
dating several hundred horstts; an infinnary is attached (o it;
also a fargcinnd s good con tilviuico for MujH'iidiiig atui H-curing

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-
ation, which, with the new remedy for locked jaw, the German
method of treating lethargic complaints, and the various im-
• Had the governorB of the Veterinary Colkge known that locked jaw ia
very rarelj cured in this country, they would perhaps have desired Mr. Sewell
lo describe the succeurul mode of treating it to which he alludea. This com-

will be published at a more convenient time.

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

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

productive of <]i»rsso, ami its total lo«s fnlul to ]\to. VrntiUlion
is necessary all the y<-u>r rotiiK): iu tlu> wiiiu-r, for cupplying
port- air for tlic purpose of liri.'viitiing lit tlie place of i)i»t which
}» impure ami unlit ; <iiid in tlie autntner, noi only for tli» pur-
yxp-t: 1)111 nUo to coo) tite stable as much as possible. Stablee
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.
'lilts plan can be furlher insured, and the litter Raved, by mt-ans

borves; for horses whint a lilde accustomi-d to each other, and

stall, e^peeully when ihcy have, an it the caitn here, wpanile niiiti-
gers, and are prevented by their halieiii from iiiicH'enng with
each others corn. The sjiace fi>r two liorses is twi-lve feel. The
mangers and rack are all on a level, and about three feel fi-om
tile ground. Tlte manger should never be less than eighteen
inclies dei-(», eighleen inches from the from to the back purl,
and two fM>l in leni^ih. 'i'he rack should \x four f<fi for one

nhoitltl be i^nulualty sloped towards tl>e ffx>nt, and should tenni-
nnie nbont two fe«i down. Sudi a rack will hold more hay than
ever oiif^lit to be put before one horse. The advantages of this
rack are numerous. In ihe first place, thcr hay is nisily pntinto
it) and ivnders a hay-loft ovt-r tin- stable uiini.-ccK«ary ; luid this
Diay be an indiKement (o ihi- builder to make tlii^ iitabh^ ■« loftv

t])e Imy that m put into this matiger will be eaten ; but in the
comniot) riu:k it i» well knovn that a large portion of the hay b
ofti'ii pulk-d down upon the lilter and trodden upon, whereby a
conuoerahle ciuanliiy is ofli-n woelcd. It prevents the hay-aee<b
or dtist from tnllin); upon the horse, or into his oyc«; and what
is of considerable iinporinnce, though seldom attended tOi there
will be an inducenM*iit to the f^ronm to fiiw the hone hay in
snmll quantities at n time, and frequently, from the little trouble
which aliendH putting it into the rack. The saring in hav that
may be efrectcd by the use of thia rack ia so apparent that it
need not bo dwelt upon. >Soinc mischievous horses will throw
out the hay with their noso« : but this may be pffeclually pii'vented
by one or two crusts bars — that is, crossitij; iIh- upper part of
inn crib front ih« back to l)i« front. * A great mving, also,
may Iw made in oats by so fastening the horse's h<»d during tlie
time of feeding that he cannot throw any of them out of ilie
manger. f If a horse a allowed a peck of oats a day, and haa, as

' the stable. In one of twelve tt.'et high, it need not come down
than five feel, and will tlicn be seven feci from the ground,
ud out of the way of being broken. The frame of the window
liould be moveable upon a pivot in the centre, and opened by
ae«ns of a cord running over a pulley in iho ceiling, and fas-
tncd by means of another cord. It is a good plnn to have two

This is more espec'tally the case when two or moi'e horses am
feeding tog;ether without a separation ; each of them is eager to
finish nis allowance as quickly as poisible, in order to rob his

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

time^ when a fltomiich hii!i bt^ii injured in this way, to n-sturc it
again; but, by )>ersisiing in the mode of feeding 1 have recom-
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
stomacb, (^nxidcrcd only lut n muieitbir organ ; for digcaiion is
performed in the home, not only by a juice secreted in the
stomach, but also by iniactilar contractions. When tltc sioinach
is debilitated to a certain decree, its secretion, tite gnatric juice,
becomes unhealthy and deficient, aiid is incapable of convertbig
the food into chyme, which is essential before the diyle can bt
cjtraeteit from IL
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.
CHAP. III.
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

small field or paddock is better than a large one; and if tl»ere
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

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

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

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

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

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

Tlie motion of the limbs Is cffvctnl by mrans of the miucln

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

Mii*des are extensively Kiipplied with vcxscls of vartoii* kiiitb)

nerves, which not only furnish sensation, bulaUocommunicalv to

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,

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

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-
ing, we find thai it is rurnished wiili a miicoiu nwmbranf, which
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
numerous contenis of the bowels are so disposed, Uuti while each
has sufficient freedom for ihc proi)er perforutance of its functions,
yet tlK' whole arc jimked away wiili the inoM economical care : —
theiv is no void to be found.
From this cursory view of the matter, it will be aeen how
numerous and compjientcd are the structures which compose
tile frame of an animnj, and yet how admirably they are com-
bined together and Imrmoiiiously agree. — Ed.]

[The skeleton of antrnal bodies is fomieil of bone, a subatatice
possessing flrmncss and stability for tlie aitaehinent of muscles,

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

cartilage a M\, which is elastic, but reuln^ the ori}{inal ligurv of
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-
sent wUc precaution, it orieii occasions greater mJachief than the
most aerious fractures. * Itetween the skull and the brain are
inteqMted several membranes, which also assist materially in
preventing vibration, just as a piece of parchment would inside «

lOt more tlian a fourth the size of the other parts of the »kutl,
iIk- remaining portions being dwoted to mafticalion and smelling.
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.
'File two I'arirtal bones are iiitimted at the iip|>er and middle
IrlB of the cranium, and cover the middle lobes of the cere-
iruin, to wliich their internal part closely corresponds. These
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
which the spinal cord, ns well as some nerves and oii artery,

mutir arch, too, is much more arched in ilie carnivora, in order
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.

however, the organ of hearing, and has on )t» internal mrboe
orifices for tlie passage of the auditory nprvo, ami on theexlertwil

internal struciure of this lione is n* bi-aniiful as it is curious;
poasm.iing vt^lihult's and canals for tlie ramification of the nerve,
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
Bcparaii-4) by a bony septum from each other, and are perforated
by A va»t nimiber of small holes for the passage of the olfactory
nerves to the na-tal cavities.

thus form the roof of lite mouO), and the cvr'ixy of tho nose.
These Iwn^'s are somewhat conical in sha[>e, the base being

'Hie Suptvior MiirUliin/ bonea form iht- greater pciriinn of the
&ice, exieiHling the whole length of the molar teeth, for which
iliese bones form saiiable sockets, and tnterallv, from the molar
leelh to the nasal bones. Within ihe cavity of the mouth iliese
bonea form (he roof of the palate, being united together in the
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
the maxillary bones, wlience they «xtefHl downwiirds, connected
lo the Inner Irancs, hut reaching much beyonil them ; they then
become larger an<l «tronK«r, so as lo ailbni deep and swure
sockets for the upper incisor teeth.
The Mular boneit are situa(e<] on llie sides of the face, above
t)>e large maxillary bones ; they arc somewliat singular, and very
irregular in shape, a pan being situated within ilw orbit of lh«
eye. They form n<vii'ly half ihe border of ihe orbit; ainl ihcir
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
orbit, the latter portion being between the malar and the nasal
bone*.

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-

inferior molar tec-tli ; iiflvr which it dimintslKA in siw, and ter-
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.

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

Now if wc consider the immense welgbi of the head of the horsef

for the |>assage of tlie spinal marrow, a part a.i iniportant as the
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
iliem Dear burdens or go in bArness, they could render us but
little st-rvicc in tliis new capacity, from the want of *lrength and
stability in the xpiiinl cohinu). Rut in herbivuroux animaU,
which are required to dmw or «ii»iiiin ln-avy weights, strength is
the princi|>al object, and accordingly we find they have much
It^ flexibility than carnivorou.i aiiinialf: this liability it the
diittinguiibing feature of the whole skeleton, but niorv [larticu-
larly of the spinal column of the horse.
The A'«A of the horse is composed of seven bones, the two
first of which will more parlicuiarly demand our attention, as
they essentially differ from the others in their aspect and their
tMC. The 6r»l is called the a/ias, from the circumstance of tts
sustaining ll)c bead, as it dw-s in man, although in the horse the
bead is rather sunjjended fritm it. 'I'he second i« allied the

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

STRUCTUHR AND FCOKOMV OP THE BORBR.
no respect to niiieK a> in tlib >ha[)<>, the •Iructurp, and bony
conformiitioii nf the fore cxirHmiiy; and certainly when we
abGcrv4' llie great leiif^h of it in »omc Htiiniale. and iu ex-
trenio fthortiiesii in other*, scarcel)' projpciinp from ihc body, in
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*

[mairrijil lu it were from the centre, and accumuliiting it on tliu
Icircumrt-rence. The exireniiiks of t)ie humerus, as well m all
lc>'lindrtealbom>9, aremucli larger than the middle portion, which
» for the purpose of aiTorthnff a greater surface for the articula>
Ition of the joinli, and the msertion of muscles (o mechanical
[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

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

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
t-very irnj)»rtatit spring, to which very much of the elasticity of
rthe foot ii owing. Man is the only animal whose heel rc$i» on
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.
CHAP. VII.
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.
Toe E&ow joint is constructed on the principle of the hinge,

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.

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.

and no less than seventeen connected with the jaws, twelve of
which belong to tlie anterior and five to the posterior jaw.
And between llie jaws, die sulnnaxillary »pacc as it b cailed,
there *re twenty-four small muscles, sis of which are connected
with the OB hyoideus, the curious bone at the root of ttw tongue:
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,
arc divided into thoito of the neff<, llie thorax, and the abdonttn.
The nitiEclcs of ihc neck arc forty in number, and arc divided

The muMilcs of the 'J^orax are thirty-seven jn number, and
■re divided into seven recions, of which we have tliree muscles
connectiil with the shoulder and the back, three with the chett,
ihn-e with the rihs ihifc with tho breast bone, and three with
the back and ribs; besides which, we Imve three large tnusclo
on the back, one of which, the luiigissinius dorsi, is of great
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
of the will.
The muscles of ihe Abdomen are thirty-six in number in tbt

KThe flexor muscln of the arm are eight in number, and are di-
led into two regions, four being deei>seated, and four su]>er-

and below to tlie bone which projects behind the knee and to the
outer splint bone. Another rises from the humerus, and also
from the ulna, and is inserted, like the former, into the trape-
zium. Tbus, there are two muscles which arc inserted into
this email bone behind tlte knee, which thus formii an important
lever, and should therefore l»e prominent and well developed.
A third muscle in this region is ullaclied above to the hu-
merus, and below to the internal splint bone, and the fourth is
attached to the ulna above, and joins the pcrforaiis tendon below.

There are Uirec miacles whtch form the front p«rt of tlie

which are often considei-ed as separate muscles. Each of these
heads are inserted into the patella below, but abot-e, two are

Tlu'se powerful niiisctes although not attached to the tibia

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

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."

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

Tlie Sfrvet, arising from the brain and spinal con), are forty

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

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

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

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.

oy a joint with two vertebnr or bones of tlie back, aitd to tlio

in young animals is chiefly cnriihiginoiin, aiid may lie !ie|>amte(l
into eight jiieces ; it aflerwnnls becomes divinible into fonr only,
and, wiih ii^-, iw consolidated into one. The ribs are extemiilly
convex, niul nre divided into the true and the false ; tlie former
being sittiated anterior to the others, and iinmedintely coiincctocl
with tlie sternum; whilst the latter are implanted into esich other
at tlieir cartiluginoiis exiremilii^, and are only connected with iho
breast bone by means of the true ribs. 'I'lwir connection witli
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

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,

'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-
ffloltit.
, 'Ilic fifth cartilage is called the Kpii/iottis, so termed from !ii
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^-
'what convex, whilst that portion nearest the muuth presents a
concave surface.
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

ecralclied with impunity after the operation of tracheotomy, the

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.

CHAP. XI.
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.

pulmonary circulation, tlutt of the system being accomplished by
iie arteries alone; in the hone, tliough the heart is the principal

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.
The arteries, ii* iltey divide and subdivide in (heir counxs
become weaker to their coals in proportion lo the diminution of
their sixe, (ill at length tlii-y terniinnle in the intuute branche*
called the capillary veKtels, which do not [msse^ any pultaiiiu;

woiiudii are hcttled, and often in n remarkably short s|>aee of
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-

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-
rishes the various orpins of the I>ody ; and supplies it with beat:
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.
^teui^«rtcai> consists of unequal parts of two aeriform fluids;
viz. 79 of nitrogen or azote, and 21 of oxygen in each 100 parts;

thus remains in these low places by its gravity. A lighlinl candle
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.
We Imvc before tlwwn, that all the blood in itie body was in
its tuni carrierl from the h<iir[ to the lungs by moan* of the pul-
monary artery, which dividi-s and subdIvi(U*s into the tmatlnt
l)ranch<>«, and terminates in smalt capiltitry veins, which, coales-
cing, h«om« birger, and convey ilii^ bloo<l ixgain to ilie Jieart by

is submitted in its course to the action of the air in the nirKM.'!!*,
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 ;
this is healthy, that injurious; one will support combuKliou ami
life, the other is unfit for breathing and will extinguish a tlame^
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

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.
M
STRUCTVnC ASn eCOMOMT OF THE ROKSE.
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.]

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

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

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

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.

vtllouB or mucous, lines the larger Imlf of tttu stomacb. It it

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

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.

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
npentnff. This gut may be considered as the principal receptacle
for fluids ; Tor it hn> been Ibuud that shortlv aftLT a lionte haa had
water, it has jmusi.-*) tlie whole length of the small guts, nitd
entered the ctucuin, whilst tlie solid food has bc«n loll bi'hind.
The internal surface of this gut is formed into cells, by- which
it is coniti<lerably extended.
On examining the inxide of the cu-cum, the part where the
ileum enii-r« will be found closed up by the internal coat,
being loou> and in fohU, *oinelhiiig like tlw i»art where tlte
cnoplitu^us euters the stomach. Tins kind of structure 'serves
M ft vnlve, and prevents tli* return of the excrt-ment into the
alimentary canal. It is necessary that the reader should bear
iu his memory ihc structure of tlii* part; for in fljitulenl colic,
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
atimeiitary canal, the cfccnm is often so loaded with excrement
as to render the escape of air impn»sible without the assistance
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 takes B course round the necuni, becomes coiisidembly smaller,
then makes a sudden turn, after which it again enlarges. It &^>n
diminishes, makes another turn, and endti in the rectum. The
first part of this intestine is formed into a number of folds by
means of three longitudinal hands, which, In-ing shorter than ilu-
inle*iiiie. causes it to [iiicker up. and form internally a number of
cells, bv which the food is retarded iu its nroaress. The second

It haa no evils, and is only partially covered by pcritoneiimt

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,
ihv left, an<l the midilk^ of which the former i» the largest, and
the lalier the smulli-st; hi-sidw iIkih? there are two tmiidl lobes.
Its figure, tlH'refore, is very invguliir, and it« colour bciwtvn
ntl nnd brown. It is supplied with nrteries for H* iiourishmcni,
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
deniiind for bile, 'llie ox, on the other hand, lilU his paunch,
and then cesses to eat lor some lime ; conset^itenily, Ite refpiires
a large supply of bile at particular periods, and tliU is allbnled

bitter fluid, and its chief usci appear to be those of a ehcinic'd
agent, |>rontoiing the decomposition of the eliyme. and, aUo,

[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
notextMid so wide us the upper, but by the lateral motion of tin-
jaws a Erinding process i* etfeeied. During the time the food
is thus Being ma&licat<.><], nn abundant supply of saliva is fiimished
by the various wdivtory gliuid.*, and the mft bolus is then passed
into the gidlel by iIk- tongue. IJy the muscles of the gullet or
pharynx the fuod is pit»e^l into tbir (iMnplioguR, by tJie miiecular

fa<-t a reason innltorded hy the hiibits and pecniiaritiesof
le animal. 'I'Ik- ox. we find, lios no l(-«x thnn four stomachs : in

for having filled bin paunch, he l>ecome» moi-e aUi^LCiiib and di*ii)-
clined lor motion : lieliei down, and his food undergoes a second
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.

obsirncting the passage of liquids, besidefl the purpose of de-
taining the food longer in the siomach. li has been (bund hr
actual experiment (hat vegetables are longer digesting than
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
ofchymiRciliun, a-i it is called, going on in the stomach, its Qj^H
ficcs arc in gnttt meuttirc rtused : but after it is effected tin M^^|
is gradually forced tlimugli the pyloric opening into the doo-
deninit, where it has to undergo llial further process of digestioti,
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

many corjw of cavalry, after being wUtioiKrd a few months near

the coitiii'ction or nyinpalliy lliat exists between the digestive
organs and iIh- skin, or, in otlier words, tlic orgim of pcrspir-

[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.]

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

four or five branches, taking their eour»o towards ibc cortical
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

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

tlic former of which will diminish the icnf^tli, and tlie latter the
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
skin ; an tlw Mecretioii of the one increiu'es, that of the other

The act of staling is more simple in the mare than in the

and is moif easily removed, which is owing to tlve striii^titniw

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

coverings, besides the skin; but there is no occasion to cut

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

The Prnit, which gcrve* tlic double office of aflbrding a pas-
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

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

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

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.]

but only by the evidence of a number of practical results. 'iTie

just as the dticlilc wax receives vvhalevcr impression tlie stamp

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

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
* Straage reuoDs are Bometimes given for breeding. On asking a fnend
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.

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

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.

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
may possess, die only wav to alleviate or remove iIh-m- dofectt
in the offspring is to sefect a horse that may excel in tbove

matter of great importance, not only because it is the surest
means of imparting a good constitution to the offspring, but also
became the possession of tins smindne^^ of ronxtiiutioi) enablrs

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.
laflunDmtion nuy be eiiti«r external or internal, local or
difTuicd. 'Hm.- flcii^ or llie nui^clt^, or sinews, may be aflt-'Ctcd
unnitet»de<l will) danger; or Ihe important internal viscera, such
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-
mation is niwiiyi! looil. Oni- or more |>jirut bear the princijuil

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

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

Infliimmation, although generally regarded as a disease, and
correctly too, is yet an eflorl of nature to n-lii-ve herself from
some irritating sub^luncc, and i* a much greater bencfli than

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
particular vise us in each horse. Intlammaiion of the lungs is,
however, moie likely to occur from lhi& cause, inasmuch iw all

place in circumscribed caritics, and likewise iu extcninl wounds,

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
termination of iiiflumninlory disrase*. An intermittent pulse
it, in a few comj*, natural to some horses; it sNo attends some
disenset of llw heart, and is by no means a desirable symptom,
for it is oflen attended by a fatal result. We can oucn pro-

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

in fever in the feet, or the pari of much importance, as in

of local inflammation ; they act by relieving; the inBanvetl vcHcl*

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.]

ON FSVEB.
[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

becomes tiolent, plungi"^ about the sull, endeavours lo bite those
who approach him, or the horsra that happen to be near him. A
horse nas been known to leap out of a small window when af-

practised in preference to (be jugular or neck veins, and I have
ommendfO the practice.
Stomach stajigcrs, though not a primarr affection of the brain,
like phreiiiti«, or mad staggers, and apoplexy, not only requires
kicking, but copious bleeding, and that too as early as posaible.

Rabiei, or HydropTiobia,

in ttie liorse by ihe bite of a mbid animal, geneTslly a dog, and
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-
ment of tlie upper lips, pariicularly of the angles of the lip."

pani^ by ihe peculiar dread of water. Towards the close of
the alfair litere is generally paralysis, principally of, or generally
confined to, tlie loins and iIm- hinder exIrviDitiof, or involving
tlioao organs which derive tiiirtr m-n'out inflitnicc from ihU
portion of tin- Kpinul cont ; Itrncc llic dii«ircMing tenesmus which
is occasionally ici^n." 'lliia disease invariably proves fatal tn the
course of thre« to six days.
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
hare become nia<l. The last case was a |xiny bitten rather
ex ten si VI -ly. A child bitten by ll»es«mcd«g, but in whom proper
ln-»tT)ient was neglected by tlie surgeon, died in about two
iMonilt^ alter tlte bite.
" The posi-morltm ap|>earance!»," says Mr. Youatt, " of rabiet
in tl>e horse are, to a considerable degree, uncertain. Nothing
unusual may be found in the membranes or substance of the
brain ; the stomach may be slightly or doubtfully inflamed, the
tun^ and the heart iitay be sound, but at least in en?ry case that
1 have seen, the pharynx, the fauces, and the epiglottis have been
considerably affected." — Ei>,3
[This difeaite is, as iu name implies, a loss of power of the
nervous syiien). It is never found complete in the noi-se, tliough
partial paralysis frequendy occui's. There are two descriptions
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

aifected side, laxative and fi-hrifuge medicine, followed by Ionics.
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

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.
TIm> treatmonl in wverc cases should consist of copious vene-
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
fciimree, and ituit hi- htia mh-u the«c worms. The stnlemiiii of
Mr. Gill, however, doi-* not (wnfirin ibesi* statement*. " I have,"

■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-

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

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.

DISKASES OF THE CHEST AND AIB-FASSAGES. 115
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.

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

be described, Imt readily beard. 'Hiis souod is produced by the

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

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
DISEASES OF THE CHEST AND A I R- PASSAGES. 119
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

" In fiivoomblc cases the quickness of pulse gradually dimi-
nishes, die appetite returns, the horw lies down; and in thrt-c

[_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

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

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.

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.]

CATARRH, COLD, SORE THROAT, ETC
[Catarrh, or cold, as it is commonly called, is an inflammation

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: —

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.]
STRANGLES. IS9
CHAP. XXVII.
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

When the glands thus become iiidiiraiedr acHne ointmeDi of

TVra/wim/. — The objecl to be kept in view is to bring tlieab*
Bcess lo Kiippiiralion as quickly as possible, and to moderate lln'
fever at the same lime.
UnlcM the syniptoiiut of fever arc tnrticularly s<-vctv, and in*

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.

and the part blistered. When matter can be readily lelt, a large

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

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

[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

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.

dispute whether in these caset litis appearance of ttie inu»cle«

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

rary or not that becomes an impcdiuicnt to respiration.

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.

a dilatation or a diminution of the cavitirs of (lie heart.
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

" 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.

chicfsympiomof which, in oiie instance, wai an emaciated appear-
ance which resisted all medical treatment, as well as th«: richest
food. The animal was >n con»e()uence, deBtroyc<l; and the
coals of the stomach were found considerably tliickeni-d, aiid in a

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

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

Keeping a horse on new oats, or new hay, is often loUowed by

looseness and want of appetite; and sometimes by excessive
sbding abo. with considerable thirst, and a staring coac A

is often necessary, also, to give some tonic medicine, or a warm

Duut now be considered. A good t'cecler, as &ucii hones are
termed, does \\a work well, and with spirit. He a seldom
craving for water, if properly supplied with corn; he eats only
moderately of hay; he carries a good carcass, as it is termed,
and is not drawn up towards the flanks, or let down in the belty
like a cow; bis dung is solid, siid not slimy, soft, and stinking;
be does not break wind much, or stale very largely, an<l his
urine is not foul and stinking. But a horie witii a voracious
and depraved appetite has, frequently, all these defects: lie
doee his uork languidly, and unwillingly ; and is eager for water
whenever be sees a pond, however filthy it may be.
This disease, for such it really is, is not always curable ; yd the
state of tl>c stomach, and coiUH-r|Ucnt)y of the whole body, may
always be greatly improved, and the hone's lite and sei'vice* con-

Professor Coli^niun is of opinion timt a mail-coach horse, wliicb
is allowed (wo |>ecks of corn it day, requires only five pounds of
~ ty. I once was employed to examine some mail>coach boraes,
1. 'i

disbasks ov the borse.
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>

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.

until ilie symptoms are fully establislied, for the animal is induced

flatulent colic, or of violent delirium a> in indammatton of the
brain ; aint, what i^ ivniarkable, the pulse is seldom aliert-d in out

But when the disorder has proceeded to some len«h, botli the

it inflanH'f the stomach and boweh; b»l nio»t conin«>nty llw
fatal termiiintion di-pends ui>on the torpor of the atoniiKli iurill
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

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

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
factory account could be given of it.*

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,
fillH ami craiuDwd to utich u deirrtv thai ii would have hccii impo»-
»ibl<^ by any mewiit in the worlil, tohavo prociiixsl the Iwfl vent;
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

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.]

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.

the violence of the f>ymploms has disappt-aied for some hours
before the liulal termination. In these latter cases tbeaitendanU

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
cannot be procured, the fomentations should be repeated, or the
abdomen may be stimulated by a blistering application. * The
* Mr. HavoT has introduced some apparatus, whereby the steam from hot
water may be applied to the abdomen for en hour together, and which is
likely to prove of greet service in cases of enteritis in particular, aa well as
in inBammation of the chest. — Felerinarian, vol. xii. p. 198. ; Fel. Med. An.

A second, and even a third bleeding, should be tried, thougli

nislies, the pulse becoming more distinct and moderate, we may
then augur s favourable result, which opinion will be greatly
strengthened by the bowels becoming gradually relaxed. Jf a

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

greatly diminUhed, if not totallygone, and tliedtseaae is attended
with much danger.
The TreatMrnt must consist in bleeding largely, if the pulse
ht strong and full, and moderately if weak: back-raking 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.

colic Thus, it appears, we liave a great variety of medicines for
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.

as the otlier, throagh which a portion of the food bml escaped ;
but the greater part still remained in tlie stomacti, and con*
sisted of a prodigious mass of bay. corn, and wheat hulls.
Tbere are beveral cases on record of rupture of the inteMliiCK,
particularly of the colon. The last case thai occurred under my
own obiervslioQ was a rent of the ileum, at that portion to wliicrb
the mesentery is attached. The rupture extended about nine
inches !n length, and the mesentery was split with it for a, cnn-
etderable extent into two membranes, ko as to prevent ibc fijod
m getting inlo the abdominal cavity,
A symptom that usually attends the rupture of ttie bowels, or
the stomach, is the spasmodic action of tlie muscles of the tuil.^

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

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-

[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
p..-)96.
Anotlier variety is a strangulation from simple twisting of the

We cannot tell with certainly that

may expect *uch w be tlic ease, when

nue without rculi*-^i^l[l til iipitc of all Ko^j,

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

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

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

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-

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'.

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

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

Chrvnie infiamwatiott of the Kvar may either follow or pre-

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 («-

Tlic symptoms arc, an enlarged and tense abdomen; the

animal baa been copiously bled, and there is reason to liope
that he is doing well, the pulse becomes quickened, and feeble

exiiaustiou ensues^ and the patient dies. In the same disease^
also, a previous altered state of tlu- \'m-r produees violent
purging from the admin iMratioti of the smallest doses of nau-

the animal.* 1 have attributed som« obstinate cases of oph-

A mass of iinpcrfc-ctly formed biliar\' fluid is therefore corrinl

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

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

It sometimes Imppens, however, that the urine t>ecomcs foul

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,

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:

forcibly ejccti'd with a spJismocHc effort. The orgiins of genera-

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

^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

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
there u a stoppage i» the water. Kctculioii of urine is generally

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.

Cakitii in the BiaddeTf
Compared with the human subject, is exceedingly rare, for many
years may elapse before a case comes under the notice of a
veterifiary surgeon. From being a vegetable feeder, and luving
water as his only article of drink, there is but little dispoaitton
fco produce these urinary concretions. Then, again, when
forntM, from the horiwHital position of IJtc animal, ihcy more
frc(juently remain in the lii<hiey»i. A few year* since, on ex-
amining iIk- body of a honie timt wiw discharged on account of
being a bad roarer, a stone, weighing several ounce*, was found
in on« of l)io kidneys. 1'here had not bc«n any symptoms,
during life, to denote its pre»enoe.
'Hiere is, in the MuM-iim of the Veterituiry College, a stone,

during life, fiir sotne lengtli of time, Itad been accuxtomi-d to

was injeclcd into llic bladder. The horse got up witltout as-
sistance, was bled ihrec limes the same day, and not allowed anv
solid food. His drink was white water (bran tea) ; the boweu
were kept open by clysters. On the fourth day lie was allowed
a small bran mash and some straw. This alton-ance was gr^

suppurated, and lookixl hentthy. Durinc some days fiArt of

it was perfectly healed." A short time since I received a letter
from Mr. VV, Mogford, some years n^o my pupil and assistant)
10 inform me that Iw had cxtracleu a stone from a hom't
bladder, which weighed more than five ounces. He says, aUo,
that Iw is convinced diat a stone of eifjht ounces miglit be

[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.
Pro(c«or Sewell, a few years since, )H*rformed the ojtcration

" The horse is twelve years of age, and has been huni^'d
n-ci'l'>'''y the last seven years, up to the period of admission

colunred turbid urine, often mixed with blood, expressing great

were incrrii>*tl with a lull into a ditch, by which he was Kuppord
to have injured the kidneys, sa it was followed by more frequent

tliat state of the mouUi which generally attends teething : it

kiiouu in regimeiils of cavalry, where it is too common.

especially in tltat part where it liearx wln^n i)»ey are put ujwn
the bit, as it is termed ; that is, wheti their noM^ are reined in
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

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

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
Continent in I7t<a. Wc «carcrly know, however, whether we
' correct in styling it an epideinic) u it nrcmi rallier (o have
nJemUj having been confuted to particular localities, and
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
.symptoms Treatineiii was in general nugatOfy, and blood*
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
biu l>een furnished.
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
have done, it would be proper to cotuider it inrcctious, and to
•vail ounvlrea of tlie fumigating powers of nitric acid gas, which

were very similar to those of tlie epizuoiie of 1696, at any

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
the morning, and at noon he n'fujkxl his feed. If I was called
vn a( this Ktinge, I usually found the month hot, aiKt the pulse
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

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

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.
"6thly. Is the influenza infectious?

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."

ject of influenza in the Veterinarian, together with an interesting
debate. — Ed.]

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
. GLANDERS AND FARCY. filA
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-
p 4

fiictoril)- demonslraled. At ihe same time, it ig gcnorall)- \x-
, iieved that ihc glanders takes p\aix alw indepenui-nt of con*
f lagion ; but from wliat causvs or circuniKtanccs it U then pn>-

animal considerably, is likely to produce glanders or farcy.
Thi-rc will be no danger in oainitlinc this opinion if, at die
&aii>c tiiiH', wc ki-ep in view the contagious nature of Ihe di>-
order, in whatever maimer it may be producetl. For if Mucb
L cruel and foolisJi treatment of liorscs does nut produce glaiiden
and farcy, it produces other disorders which are often more
speedily IJilal than glanders ; and if it does not actually produce
B disorder, it weakens the constitution to such a liifgrw that the
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
glanders »])readB so rapidly among post aiKl stage coach bones,
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-
fully attcu<lcil to, nor whh tlie general inanageuu'iit of ttiose
horses in any respect so good as tliat of Mr. Kussel's. In con-

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

jaw become larger, harder, and fixed more closely to the jaw
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 ;

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
ssa

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

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

proceodinjt from a glaiulercd horse, or a stable in wliicli ■
slandered horse is, or has been kept; secondly. Uiat the degree
in which (he glanders takes place dependa on iwoeircumstancn,
chiefly on lite quantity of matter applied, and next, upon llie
sute or health of the animal that receives it. Tliie is more
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
by eating the glanderouii miiltvr mixed wlih outs orliav, thanby
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,

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

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

If tite puUe ia increaaecl, ilion^flt only eight or ten beats in a

duly ; and if there are none visible, it may be well to try the
efTccl of fumiKJiting the noatriU with carbonic acid gas: and

which are, indeed, the diseused lymphatics; and ilie buds ore
considered to occur at the situation of the valves of these
vessels.
Farcy may at first bo citl»er local or constitutional, but it
mrely remain; local long. The pobon U soon absorlied fi'oni

nix-k and ihe lips; wherever, indeed, the skin is thianoi.
^
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

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.

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

CHAP. XLIV.
THE srKl'CTt;llE AND DISCA8SS OF TliK SKIK.
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.

letting and purging should be abstained from, and tlie following

[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

When the disease has existed sonte time, iis appearances are
loo striking to be for a moment mistaken ; but in the earlier
fitages ii may, in a great measure, be detected by rubbii^ the
animal with a stick, when he immediately exprctses his pleasure
by elevQiiiig and moving quickly the iippiT lip, and fxtendinf;
the head in » peculiar manni-r. Il is likewise by t)K> dtminulini)
THE STRUCTURE AND DISEASES OP THE SKIN. 243
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

or no danger of infection af)er the ointment boi been thorouglily
a|)plied. Unless tbe animal is much warned, his best ptaice it
at Krass during! the profjrcss of the cure.
The mange is very fre<)uenlly ailcnded by the presence of a
great number of Iic4>, and sometimes these lice occur witlioal
the mange, and occasion an itching similar to it. If they caaoot
be removed by waBhiiig, the ointment for mange will destroy

MaUrndm and SailetKten.
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
back part of the leg, extending from the fetlock upwards.

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

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;

by various muscles, and bedded in fat, in onler in atTnnl fuciliiy

resembles parts of two clobei, a negnienl of a smaller one being
apparently joined to the frustum of a larger one. It oonsisti
of several humours, and of various coats or membraives;, some
being traiisparfnt and oth<-rs opaque. In describing tlie ana-
tomy kiid physiology of the eye, the moat convenient method is
10 divide the subject into two parts, that is, the eye itsell^ and
iti appendages. Under llu- latter bead is comproheiided ibe
eyelids, the mustles which move them, the eyelashes, the la-
chrymal gland, the puiielu luclirymalia, and lachrymal duct, ihv
caruncle of the eye, the haw, and the mcmbiane named con-
junciiva, atHl the muscles by wliicli l\w eye is moved.
'Hie pl(lp(-bn(^, or eyeli<li', may be oon»idere<i as the shutters
of ill* eye, their office being lo exclude light when so required.
Tikey tsonust orcnrttloainous bodies covcnkl witli soft and elastic

arc moved by two kinds or orders of muscle*. The onu, com-
posed of circular libi-es, and named orbicularis, is ■ituat^'d io>-
medlaicly under the skin, and, by contracting, cIomi the ey^
lids : ihc other, named levator, is composed of straight fibres, is
situated under the upper eyelid, and, by contracting, opens ilw
eyelids. The margin of the eyelids is smooth and thickeitnl,
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-
rate ttie light which comes diiectly from the sun, without oQeriug

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
860
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-

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

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

I» cataract, a disorder in which the crystalline lens becotnes

stale of the band of circular librcs; the same effect may be ob-
>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

contains tlic thinl or vitreous humour, with tlie clwiroid coal,

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

[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-

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

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

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

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

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
an object appears green, or blue, 01- yellow. Wlicii it ap|h<ars
whi((> nil th4> colours are reflecte'l, and when black tliey arc all
sluorlMsJ.
It in a law of optica titat i!)c angle of reflection and that of
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

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.

Mr. PeatI, in hia ob»ervattona mi tlie diseases of the horse,
relates a striking experiment which he made on a horse afircted
with ophllialmio. " I have ordered him." he mvs, " to bo r*r

much light ; and, in lite course of a few minutes, have observed

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

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
nnd cruel tntinnpr in nbicli i)i« nninuU ii workedf and the rarly
■gu At wliich he ia bioiiglit into work.
\_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

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
lltnt connect the shoulder blade aixl the humerus to tlte body
are .strained, and this genemlly ariMtt from the fore higM slipping
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

'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

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

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 —

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.

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

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.]

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.}

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

"The more nioctem, successful, ami scientiftc treatment of

" Profeaaor Sewdl has introduced, within (liete few yvtn, aii
excellent mode of performing (he operuiinti. The horse i* caxT,
(he leg properly straightened und M-cun-d, and then a small
opening is made just below tlw spliut, sullicieni to inlrmluce a
long, narrow, convex, probe-pointed knife, the edge of which is
on the convex side ; the knife is Uien passed up under the skin,

In ilie very numerous cases that occur of splints being mi-
Uiended with lameness, it is better 'to let well alone;' but
when the lamcnesa is slight, and the lu>rse cannot be spared

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

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.

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

of the joint capsule, throu{(h which the flexor perforan* t<-tidon

the lower posterior pari of ilie tibia, and prevents concti^ion
between the tibia and oa nilcis when tlie leg is suddenly and

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

ligament constitutes a curii, altltough the flexor tendons are

Strain of the Ligammlt, tfc.

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

Blood spavin is a fanciful disease, and therefore requires no
further notice. — Ed.]

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.]
CHAP. LI.
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

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.]

The treatment of serous abscess is sometimes tedious and

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

lower situated than the extci-nal one. A broken knee may be

„ 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.

[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.

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
STnUCTURE AND ECOKOMY OF TUE FOOT. M9
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

and liiat the deficiency in this circle it

shall find that every part of the ex-

this should be considered as the natnral

to cover a gi-eat dwil of the bottom of the foot.
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*

LjtfoMO, who was cotemporary with Iloiirgelat, ninl who
ereiitly distinguished himselli not only as a veterinary writeT*
util ns n practttiom-r of the art in all its briuieliett, givi-s a dp-
scripiion of the shoe he recommends for a sound foot, which is
the once celebrateil half-inoon shoe, litis shoe ■ann toon after
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
and the frog may Iwar on the gmiiml. Very liiilo covt-r or

never to be [liired, being with thii iiIkk- fX|>on'd lo the pressure
and frieiioii of the ground, which is siilhcieni to wear awev
wliatever is superfluous. Tliere is something in this ithne whicn
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

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,

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-

matter undertKWth, and that it ought to be let out, however
thick the horn may be which covers it. If there be no matter,
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-

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,

when ihe pflrt of the fool or shoe (most freqiienltv it is tilt

I have seen a severe lameness produced by a lionie striking liu

for an injury of ibe shoulder, because, (hough it was evident iliu

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

doubted by surgeons; but in horse surgery it will be found the
best practice. WIten the inflammation nas been completdy

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

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

frog, tite putrid and acrid fluids pcnctrste through (he Boakeil

discharge a fetid acrimonious matter, instead of tocreting liom
for its own defence, as it does in the healthy state.

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.

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

dry and of n yvllow colour, and ou the turr»cc of iIh> nut boae
tlwre were nuiny minute bony (fxereicenoea, about the size of
millet seeds. In tbc second, a stage-ooach hone that bad beeti

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

tilage had been worn.
QIi has now been otcertainetl tttat lite chronic disease here
spoken of, which used ut be attributed to the contraction of the
foot, is almost invariably seated in tltc navicular joint, and
that contraction alone, althou(;h it may bi- botb a cause
eiTect of ilie other disease, dot-s not, in itself, pi-oduce lac
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
diM-asc is due to Mr. James Turner, of Regent Street, LondCDi
who has written various essays on the subject.

PoiHtiatt, or resting, b an almost invariable H^ninioin ; the loot
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.
The cautis of ihis diM-tue aiv eitht-r jircdiKposiiig or exciting.
Long reil in the swbic without exerciiic, the heat of the litter,
and the confitieuwm of tlie >h»e, all pn-dl^poec the joint to he
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

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.^

\ The aitualiona most favourable fur lucul bleeding are the toe and co-
ronet in both hind and fore feet ; the inside of the arm and elbow ^oliil in the

tbe palate. A fleam i« the moit convenient inilrnmcnt in blredinK. either

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

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

lai^^ed. This denotes a stoppage in the passage of the blood,
which therefore Itccomcs stai;nutit, and cltukcK up the roeaels

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 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

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

floor moat be subttituted for it. This will almost always be
found to be effectual ; but should it prove otherwise, give a tea-

The strength and composition of physic will be found in the
Materia Medica.
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

removed from llie stall, and the liorse'a Itead sboultl be carrrully
secured, to {>revent his rubbing the blistered parUt with his

neck, and lie turned loose into a large boK, or a paddock, or an
orchard. In a lield he would be apt to take too much exercise.
About a week or ten days afiet tbc bliaier has been applied, (he
parts should be oiled with some mild oil, such a^ olive oil, or
(nth made neat's foot oil. If fites are troublesome, and make
the tiorse restless, ihcy may be kept off by the tar ointment^ or
tar and Imin oil nii\e<i.
[The formula for blisters will be found under that head in the
Materia Mtdiea. It will ihcrc be seen tliat cantharidcs forms the
principal and indispensable ingredient^ atKl thai its effect ie to pro-
duct* considerable p&in and irritation. Tlie statements put iorib
therefore by the puffers of quack blistering ointmenta to the
effect that their noglnmis produoc no irritation, and that no
precaution nwA be exerciM-il aflemards, arc allogctlier follariofle,
and calculated to do much mischief. Tlw fact is, the greater
number of hones will not rub or blemish tht'iuclTcs after any
blister; but if one in ten will do so it is desirable to use pr^
cautions with the whole number. If, however, a very slight
blister is used there will be no occasion to tie up the head, at
lite irritation will depend on (he degree of vvsication excited.

not twisted tight, but made 6exible, like a bell-rope, and about

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

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-]

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,

begin between three and four incliea above the fetlock joints
that is, (he most prominent part of the side of the joint, and
extend downwards for an inch and a half. By makinc a free in-
cision in the space that is felt between the bone and ligament,
and the tendon, the nerve may be almost immediately exposed ;
and it ii only necessary to remove a little cellular membrane,
and then it will be distinctly seen: one inch or more of the

THE NERVE (>IT.nATION'. SAB
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

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

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

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

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
it on that portion of ll»e cord which I intend it to embrace
before I apply the forceps, i then draw up lite artery, wliiUi
be xeeurcs tltc ligaturo. This I consider tlie moftt importonl
(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.]

Oh Hmia or Itu/ilmvt,
[This iliwase consistft in the escajie of tlte bowels or otlSr
viwiTa from their proper cavity. There are two priiicijul
VAfieties of hernia: onv in which liie intestine escapes thro^|{li
the abdominal rinffe, which, in the liorse, continue open ; and the
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,
which laltcr lie dilates to the extent of three or lour ineheii by
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 srntJCTirnE or the teeth, and the method nv

[The hone has, at five years old, forty leeih ; vlt, twentjsfcur

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

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

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

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

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.]

If a person, inexperienced in llie mysteries of horae-dealti^
wish to ptii'chase a horse, be woukl do well lo consult a |>rofrs-
gidual man, or some one capable of guarding him against any
deception that might be attempted, and of pointing out any di*-

It would be useless to attempt a minute eKaminaiion of m
horse while the dealer or his asiiihlants are present: the doping
grouiKl upon which the horse stands for examination gives a de-
ceptive view of his form and height, while the couRUnl fear Ite
feels of the whip, and the high-flawn panegyrics luvinhed upon
him, are so perplexing to a person unaccustomed to the busi-
ness, that be is apt to overlook the n>o5i pal[Kible d<'fec(«; nor it
it possible for the most experienced lo examine liim witb all llie
accuracy and attention iliat are necessary ; as aii unolwerved
flourish of (ho whip, or some other priTa(e bint from the seller,
ki'ejw the horse constantly in motion, partictdarly when the eye
liHppenx lo be directed to a part that he does not wish to b« in*
Epei'lcd. I do not mean to my ibat this is always ibe ewe;
there are many dealers, no doubt, of strict integrity, who affi>rd
ample opportunity to those who wish to examine their borsm;
iintl, so tiir from wishing to practise any deception ujion tlw iD*
experieuc«d, will never warrant a horse to be sound uidew they
are convinced (hat he is really so ; but that (here are men in tW

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

to deserve notice. It should lie recoUecied, however, thai Uh«
trifling cracks in tlie hoof indicate an unnatural dr^'tieu of the
horn, and, con3e(|uently, a tendency to sandcrack ; ilterefore.
when such a horse is purchased, proper means sitould be eni-

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

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

there is no difficulty, as the horse seldom makes any considerable

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

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\. \»

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

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." —

It is the duty of a veterinary surgeon to point out blemishes

doubtful points, such as curbs or specks in the eye, a specific

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

only be equivalent to fifleen groins, instead of a scruple or twmtj

In Crabb's Technological Dictionary, the French litre ii
stated to be equal to the 35tb part of an English bushel, which
contains 8 gallons or 32 quarts.
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
400
ffur^infft. When iii^- or musly oats arc tin* cati*o o( (i»c ilseaAt
ana betier cannot be liati, they sUoiil<l bi> drinl on a tnall kiln:
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

sometimes found in burses' bowels, most commonly in mtllen'
ItorsoK. I liavf seen one that weighed eiglic pounds, and I lliiok
there is one in the Museum of ihe Veterinary Cotle|^, thtt
weighs ten pounds. Cattle that are tied up during the wJntff
often acquiiv a propensity to lick upeanh; they also, m ibeir
coata become loose on the approach of spring, are frc^uendT
licking themselves, and often swnllow a great ^1 of hair, whicli

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
■he evaporation is completed by the heat of the sun. Tliere nrc
two varietiea of tliis extract; one brought from Dengiil, the
other from l)oml>ay. The latter kind is ot a pnle reddiah'brown
colour, and is generally in small square cakes; the other is in
rtrund masses, of a deep chocolate colour internally, with the
hue of rusty iron on ihe outside; it is liearier than the pale, its

ACACLi:(JUMMI, ACACIA GUM. Gum Arabic. Thii
gum is procured from the bark of a species of mimosa, which ii
very common in Egypt, and Arabia Pelreea. Several other
troe« also produce it, and it is remarkable that the bark» of those
trei» from whicii it is obt^ned are extremely bitter. Cheny
nnd plum tree* are an instance of ihis. ITwre are two prinoptl
sorts of gum Arabic, one procured from the Levant, aiiotlier
from the Easi Indict, 'llic latter is ilie darkest, ts not lo
readily soluble in water, and forms a thick(;r tnuciliigv tlian the
former. The mucilage of acAcia is fonncd by gradually adding
half n pint of boiling water to four ounces of tlw giim in powder,

ACETATE. A salt formed by combining aoeiic acid or
pure vinegar with an alkali, an earth, or a mciallic oxidf.
There are several acetates u»ed in Veterinary Medicine, coch of
which will be noticed under its reepecti\-e name.
AcxTATE op Ammoma, SoLirrioN OF. — Liquor jimmatiir
Acatatit. Formerly named Mindererns's Spirit, and is made bv
adding vinegar to carbonate of ammonia in powder, until >I
ceases to produce effervescence ; about an ounce of the carbooBK
of ammonia will be Kutficienl for two pints of vinegar. It tnsy
aUo be made, by adding spirit of hartshorn to vinegar till it
loates neither salt nor sour. Mr. illaine strongly recommends
this medicine In febrile dtsewe, and epidemic catarrh wlicn
debility is present combined with camphor and camomile. Its
action is diaphoretic, slightly diuretic and tonic, tlte dose from 4
to 6 ounces. 'I'he Editor lias given it in influenza with good
effect.

ana has been used with guoccsb as a i-emedy for quittors.
Acetate of Lead. — I'lumbi Acelas. Is made by mixing on«
pine of strong acetic acid (vinegar) iviih a pint and a half of
boiling distilled water, and tlien adding gradually one pound of
aubcarbonate of lead. The solution is llien to be filtered
ihrou^i paper and evaporated until a thin pellicle appears on its
surface, when it may be put by in order that cryalala may form.
Tliese, after pouring off the water, are to be dried upon blotting
Bper. The superacetatc of lead is commonly named Sugar of
■ad, and (be liquid subacctate, Goulard's Extract of Lead.
Mr. Morton recommends sugai' of lead for internal liGemorrlmge,
and for protracted diarrliipa and diabetes in doses from half a
tlrachm to a drachm. Sugar of lead has been given internally ;
but I consider all ilie preparations of lead not only uniieceHwiry,
but dangerous as internal lemedies, though one very large close
may be given wtdiout any perceptible effect. AnimalM have
often been jioisoned by grazing in the neighbourhood of lead
mines; tliis is well known in the parish of Wuokey, near Wells.
The disease tliu* produced is there named minderini^ ; or rather
the animals %o aflVctcd are said to be tnindemt.

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

sufficient to destroy many large animals.
" By the I'harmacopteia. it is directed to be prepared of such
strength, that (wo parts of real acid shall be contained in 100
parts of the dilute acid. Dilute hvdroevanic acid is a trans-
parent liquid, free from colour. Its action is that of a power-
ful sedative, and may be given to the liorse in doses of from
half a drachm (o a drachm and evni more ; for it is surprising

tranquillising the excitement of the motor nervi,^ and thus
olluying the general muscular spasm." — See Morltm't Mantuil.

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

seized with the fret or gripes. From 2 to 4 or fl oz. dilated
with water are the doses generally employed. If a liorte ii
unaccustomed to ihia cordial, or to beer, a small doee will
generally be sufficient. When we consider that the excitement
produced by cordials, e4i>ecially diluted spirit or beer, is only
temporary, that it caiiwa a greater flow of nervous i>ower or
animal sjiiril towards tlie stomach in particular, .and likewiBe to
all the musctilar system, it must ap{)ear evident lltat it has a
tendency lo weaken tite sensorium or brain, as is proved by ilw
excitement ii produces being alw«^-s followed by more or leK
depression in tfie stomach, and all the organs of Uie body, ac-
cording to the degree of excitement thai has been produced
From this consideration it is obvious that wc should bo cautious
in the use of spiriiuoitscordialsi, ami not give stronger doses ihna
are necessary. It is not an unusual thing to give two botlloi
(almut a pint) of Daily's Klixir, a tincture made with proof
spirit, at a dose; sometimes unrlilute<i, and even mixed witb
pepper. Haifa pint of gin, and two ounce* of pejiper, is not an
unusual doBc with siahU'-nieii lor grijx-s or fret; and as it often
cures the disease lliey think nothing of the cnnsequencrs.

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;

some visible t-fCvci upon the bowels, the kidneys, or the skin; the

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
of \ona standing, or ewn when thry arc rccvnt, if not cautnl 1^
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,

an expectorant quality, and is therefore given in coughs and
other complaints of the lungs, but is generally joined with other
expectorants. It b certainly, thougn weak, a very grateful sti-
mulant, and does much good where the stomach is weah, and
disposed to flatulency; it is therefore an useful ingredient in
eonlial medicines. The dose is about one ounce or rather more.
(See Cordials and Carminatives.) The virtues of anise^eed
are contained in its essential oil, the dose of which is about half a
drachm or more: it may be rubbed in a mortar with sugar, mu-

In the human being anise-seeds are supposed to increase the

generally considered llie most eflecinal anthelminticB.
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-
Phtir, and tin, have also been considered as a/ttftelmiafict. I
clievc tin tiaa not been fairly tried : and as it is an efScacioiu
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^

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
i» given, the stomach should not he in su i-xlmuxtet) a xttttt: by
fasting as it appears to have been in one, if not nil of the above

which is not generally, if at all, known. Since 1 have resided
near the Hill uf Mendip, I have frequently met with u kind of
worm in the bowels of horses, dogs, and cuts, which I never

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

perfectly innocent in the dose commonly employed ; and joined
with nitre certainly produce a good effect as an auxiliary to that

ANTISEPTICS are medicines which prevent putridity, or

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

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

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

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

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^
witli tbe lell hand while the ball is tnlrcxluced, great cnrc i* ri^-

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

BALSAMS. — Bahama. Balsams are generally fluid, t&
various degrees of thickness, odorous and combustible : they re-
semble resins, being soluble in spirit of wine; and when thin
dissolved, impart to water a sweetish taste, and s milky if-
pearance.
Balsam of Canada is a very pure kind of turpentine; and
though preferred on this account to Venice and common tiir-
peniinc, is imneceasarj* in veleritiary medicine, |}«ng very ex-
Eiisive; whereas Venice uirpentine is mucli flic«i)CT, and I
licve equally efficacious.
Canada Sabam 18 a strong diuretic iti tlie dose of one ounce

Morion for the preparation of tape or cotton for octons. See

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

I1.\RVTA.— jfVrro Ponderout. Barytes. This mineral ha*
not yet I)een discovered in an uneombined stale. It is usually
found united either with sulphuric acid or with carbonic acid ;
from which combinations result the sulphate of barytes or htan/
fpor, and the Ciirl>onale of barytes, or teitJierilf, so denominated
after ils discovei'er, Dr. Withering. Doth these substances are
used fur making the muriate of Iraryles, the only preparation of
thi^ niineral in gtrneral use. It is a medicine of very uncertain
jjower, and »hould l>e used with the greatest caution. M. Dupiiy
giire ti tlrachniK Qd grains to a ghuidered mare, of which dose
«he shortly after expiied. Mr. ^^'illiaIn Percival made some ex-
p«'rinic»tit with baryte* upon glandered horses, the results of
which were variouK, and yhowed that, although in some comh
poranurd of con(iderabl« efficacy, it is not altogether a medicine
to be relied on. .Some of the horses treated by Mr. Percival
were destroyed, without their having received any perceptible
benefit from tlie barytes. Olheis were completely cured by ils
■dmiiiistration ; and not a few died fi-om the effects of an over-
doisc. In genera), those horses thut were in pretty good condi-
tion at the time of their odmis^ioii into the iiiHrnniry were found

BATHING. A remedy seldom employed in the diseases of
horses. The warm bath would probably be found useful in
' tome cases, and appears to Ite used in the French veu-rinaty
collvges. I have lieeii inlbnned, lltat Mr. Maberty, of Spring
'Park, Surrey, was Ibrmerly in the habit of putting his honM
ill a warm bath wlienever they returned from hunitng. Tbi(,
although only within ilie reach of people of fortune, is a very
exoi^lent praetioe, as there is freipiently congestion of some par-
ticular organ, as ilie lieart, lungs, or liver, after excessive fatigue,
and tlie warm hath, by drawing the blood into the capillnrics of
the skin, tends to relieve the ovi-r-londed oi^iiii, nnd thcrebj' W
equally' the circtiliiiion. A tojiicnl biith, both warm and cc3A,
applied to ili<- f«-i and tegs, is often of gw-ai n-rvice in lameness-
llATII, VAPOl-'K. Though a \-ii]>our Ixilh would be veiy
servicable on many occasions, yet from ttie difficulty in eoa-
•Iructing it nnd the exponso attending it, it has not beea
generally used. Mr. Mavor has invenied some apparatus for
applying stcHiU locally ; and Mr, Head is now dei'oting his in*

BELLADONNA. Deadly Nightshade. "A powerful nar-

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

and the juice evajwraied unlit it has acquired a fit conoist-
eitce.
" 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
are present, as tetanus, carditis, and pneumonic affections gctic-

litgtily of it, as do many other practitioners. It is given in dosca
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
pupil. The same elTecl I liave witnessed from a lai^e quantity

of ttramt, hraisex, &c.
in inflomniaiion of parts remote from the surrim*, tbev are of
great service. When the internal parts of the foot are influaiMlt
relief is generally obtained by blistering the paatern, provided the
subordinate or auxiliary lemedios are not omilte<t. such as paring
the sole, soaking the horny part of the tool in wnrm waier, or
applying a poiilticf lo it, mvd giving a dose of physic. Wfvn

remedy, especially when we feel doubtful as to tlie propriety il
further bleeding.

lous swelling on tho part ; for llic removal of which blistering i*
employed. When bliBters are properly made, and free from any
cttti&lic ingredients, such as sublimale, vilriolic acidi iic, thore ii
no danger of destroying the hair ; and if tlie Krst blistering does
not prove effectual, it may be repeated until die desired effi^ct is
produced.
Before a blister is applied, [he hatr should l>c closely eut olT> or
even shaved olT if the situation of the diseased pai'I will admit of its
being done without wounding the skin ; but good scissors or shears,
ifskilfuUv used, will answer the purpose sufficiently. If the sktu
isscurvy iim;iy be washed with flannel, soap, and warm water, aud
be miidc perfectly dry before the blister is applied. Blisters are
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.

cascarillo, and other medicines which contain lannin and ibe

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
Laxatives.

Some praclilioncrs, liowcver, direct a small thin nuuJi of bnn
only to uc given about an hour after, for the purpose of diMolrii^
or mixing with the phyxk. It li a good plan to give a modcnie
quantity of mash about two houn before the physic is given, u
eoiiie hoi-sed refuM^ it altogetla^r sfliTwnr(l». If ihi» la not done
n little should be given about an Iwur after tbc physic, brfore

or improper on ilic day the physic is given : and on the foUowing
day, when the nie^licinc grncrally operates, tlioy are npt to gi«>
loo much exercise. But as loon as the purging has taken place ia
a sufficient dtigrer^ which is generally the ntsc about die KUemoon
of the day after it ts taken, exercise is unnecessary or improprri
and should the purging continue or be found to be ffoing oti lb*
following morning, that is, on the morning of the third day. in-
cluding that on which the UKdicine wus given, it shouhl bu re-
»tr<iiiic<l by grtiel made of arrow-root or Itnc wheat flour, wiih

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

It is necessary to stir (lie mixture well after it has been in the

corporated, Mr. Chirk directs it to he poured into paper moulds.
I liave found, however, that by pouring l)ie mixture upon a

quires n proper consistence to be formed into balls.

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

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.

CINNABAR, or RED SULPHURET OF QUICK-

A heavy mineral of a dark red coluiir, sotnetinu-« prepared arti-
{ 5eially. It b corapoeed of cjuicksUver and sulpliiir, called red
sulpburet of mercury, and has been employed la nn alterative
in obstinate coughs, and t)>icknea§ of vrtnd, tn dowG of half an
ounce daily. Cinnabar h the lea&t active of the mercurials.
CINNAMON. — Cimuimomuni. The cinnamon iree !b a
native of (be EaM. The bark is rolled into cylinders and ex-
ported in this state. This well-known spice is a powerful sti-
mulanl, and an excellent cordial: iu high price, howct-cr, pre-
vents its l>eing used much in cordial preparalioitx ; m> iliiit w-lien
good cassia can be piociired, it may be, on all occasions, siibsti-
tuled for it in veterinary practice (See Cassia). Oil of cinna-
mon is mndc by maccratini^ cinnamon in sea water for forty-
ei^ht hours, then distillinj; it with a gentle heat, and separating
the oil from the water with which it come* over.
CLOVES. — Cart/iip/iilli, A stimulant of con.tiderab)o
strength, but seldom employed in veterinary medicJni-, on ac-
count of its high price. The essential oil of cloves is Nonietimcs
used) in the dose of ten or twenty drops, in cordial preparntions,
or in purgative medicine, to prevent sickness or griping. It is
an excellent cordial.
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

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

plished without raking or drawing out the hard excrement with

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 •
native of India, Cliiiui, and oilier places. Kvery part of d»
ptnnt appears to possess medictiuil properties; hut tlie Mvds
alone arc employed in Europe, 'i'he t«eds are about the sin of
a Kinall colTee bean, and aliound with a fixed acrid oil, whicli is
obtained by expression, constiiiilin)^ the croton oil of comincrco.
'i'he oil lia» a bright sUaw colour, a iaint odour, and a but ocriil
taste, creating an uneasy sensation in tlie throat. It ia Mlnble
in alcohol and ctlicr.
The oil is merely a vehicle for lite acrid principle which »
called tigfiH and crolonic acul, a portion of which rcnutiu in the
farina after the oil is extracted.

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
Munuah
DAFFY'S ELIXIR. A popular quack medicine, often
given to horses as a remedy for flatulent colic, gripes, or fret,
which it sometimes cures, being composed of proof spirit, in
which senna, jalap, caraway seeds, and ginger have been in-
fused. It is by no meanfa an eligible medicine, and should never
be employed in this complaint. When the remedies prescribed
lor this disorder cannot be obtained, a pint of warm beer, witli
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;
* I am in the habit of combining croton oil with sloes with good effect. I
find four drop!) of the oil added to five drachms of Cape aloes render it equi-
valent to five drftchois of Barbadoea aloes. — Ed.

to a quart of water. This decoction is used as an anodyne fo-
mentation.
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.

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

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

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

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

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
an e^, or a small quantity of some alkali (see Alkali).
Emulsions have a milky appearance, and are a convenient vehi-

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-
lage of gum arable. When these have been well rubbed, water
is to be gradually added.

siccated sulphate of alumine (burjd alum), acetate of copper
{crystaltixed verdigris), sulphate of copper [blue vitriol). These
are applied, either separately, or two or more of them are mixed
together, and finely powdered ; sometimes they are mixed with
bole arnienic or chalk, or with lard or digestive ointment, by
which they are rendered milder.

ESSENTIAL OILS. The smell, taste, atid other qualities

KXPECTOK ANTS. Medicines that increase the dnchaiw

culty of breathing. There are many medicine* which produce
tliis elU-ct in ihehinuiin body; but in llic hone the action at
fjCjirrloranU is not so perceptible. Some of the nti-dicines, boW'
ever, termed expectorants, prove H?rviceahlc in the horse,
relieving or curing cough and difficulty in brculhint;, or what
termed thickness of wind ; among these arc squiti, and gn
ammoniacum ; both which I have often found beneficial in thocc
complaints. But the medicines 1 have found most useful in
chronic cough and asthma, or broken wind, are mild diuretics
joined with cordials. 1 have known the occasional use of oor^
Itlial diuretics, when the horse's diet is carefully attended to, not
only relicvp but apparently cure broken wind; but the hone'i
work sliould be moderate, and so coiidueteil as not to interfere
with digi-stion.

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-
tmiing thrinigh it. The violent inlluunMation this oecasiona
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
is itecessary to observe that the milder remediea should be tried
before this severe ojKTatiun is resorted to.
It has l>een assetted, that when firing is employed for old
callous swellings of the back sinews, the swelling should bo
previously reduwd by bliatering, and that firing will then pre-
vent any return of the complaint ; whereas, it" the firing be per-
form<il in the first pLice, it will tend to fix the swelling, and

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-
plying it is by means of a long piece of woollen-cloth, with the
two endfi joined, tiiat it may be wrung out of the hot fomen-
tation, by placing a stick through each end; for the liquor
make) the cloth too hot to be hnndletl and wrung out without
this contrivance. When thus applied, it may be considered as
a steam fomentation, and will be found very beneficial. Two
men, one on each side the horse, are required to apply this (b-
meniation efieetually. In some cases, where the swellmg or in-
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.
[Mr. Mavor has iniroilticccl some apparatus for the topical
application of steam, which is noticed iu a previous part of th«
present work. — Ki>.]

llieivfore, introduced into vcierinary praclicc. Tite oilier com-
plaints in which it has been chiefly employed, are chronic cough,
or imperfect wind, wid swelling of the legs.
Pox^ove is an active medicine in the horse, and cannot be

fumi^^otion, having found that when glnnderous matter is ex-
posed to it a §hort time, it is rendered perfectly harmless, The
fumes which are generated by pouring oil of vitriol, or vitriolic
ncid, on powdered nitre, are said to be very eETectual in deetroy-
ing human contagion ; how far it may be serviceable in vete-
rinary practice remains to be ascertaiued ; but, as the fevers of
|]or«« do not appear to be infeelious, there i? no great proba-
biliry of its proving useful. The term frmifi/a/ion is applied, by
French veterinary writers, to the vapour arising from boiled
licrba, or bran and hot water.

a simple or medicated fumigation may be conveniently applied

GALDANUM. — Galbnmim. This plant is a native of
Syria and some parts of Africa, and alTords a gum-rr«in, similar
in its medicinal tjualities to amnioniacum; that is to say. anti-
spasmodic, deobsiruent, and expectorant. It is, however, in-
ferior to the latter medicine in cincacv, and may be said to hold
a middle place between it and assafcclidu. The dose is about
three drachms.
GALLS. — Gallie. An excrescence firom the oak tree, pro-
duced by tiie puncture of an insect. Galls arc poiverlully
astringent, but not olien employed internally; I hey may, how-
ever, prove useful, in conjunction with othei' remedies, in sup-

violent catliartic, oHen producing nau»ea and vomiting ; but it is
very ratvly used for velerinarv purposes, as it* dTvcU are uo-
certnin, and it is liable to produce griping.
The dose is from two draclmis to half an ounce ; or two
drachms of gamboge may be combined with three ofalors.
GARLIC, — AUium. This is ol)en employed by tarriere «
a remedv for coughs and thickness of wind; and 1 brliirvc thnt
in coughs of the chronic kind it ha« sometimes iH'cn found
efficacious.
The dose is from one to two ounces.
Tlie cloves are separated and pounded in a mortar uniil t]tey
form a sort of jmsIc, which is formed into balls with liquorice
powder; sometimes ihey are boiled in milk, and given tn the
form of a drench. Gibson speaks highly of garlic.
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

GEUM rUBANUM: WflrfiV. The root of Aveiw. This
ia an indigenous perennial plani, flowering from May to August.
Its odour is fragrant and spicy, and its taste bitterish and
uttringenL lis pioperilei are astringent, tonic, and anti-
M^>tic, and it may be adTniitageoiuly employed in those ditrases
which depend on a ivlaxed slate ol the system, or of any pnt^
licularimrl ; as in dian-hceu, red-waler (where no fever exisis),
tke. This medicine has been much more extensively used o(i
AMD l>HARHACOP<£IA. 487
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.

Goulard poultice is made by mixitig as much of ilie lotion,

Goulard Is never used undiluted, nor is it given internally.
GRAINS OF PARADISE. — Car^amomum. A waira

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,

medicines as are of u stimulalmg or acrimonious nature, such as
oil of turpentine. Gruol is made citl>er with oatmeal or groats,

tbev work bard, or an a reMoralive cordial, liifiiftioii of inalt
makes a good nutritive drink for horses; but good sweet groats
make an excellent gruel. Oatmeal is sometimes niuity, and
gruel made with it haa often some degree of bitterness. Wbeit
gniel ia given as a cordial restorative after bard work, a little
beer and ginger may, on some occasions, be added. Hor»e* tbut
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
from the smell of meat, smoke, or lat. For some purpose*, or
where it is inconvenient to boil the gruel, a little oat, barley, or
wheat meid may bestirred into viarm or cold water.
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
drachms.
When guaiacum is iidultcraied with common renin, if a por-
tion of it be thrown into fire, an odour of turiK-ntiiie will int.
mediately be emtlled.

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.

HOG'S LARD. — Aii-pr Suillus. An article of some im-
portance in veterinary surgery, being the basis of almost even'
ointment.
Hog's lanl poBsesaes a laxative quality, and may be given to
the extent of half a pound, melted and mixed with warm water
or peppermint water, as a substitute for castor oil, olive oil, or
linked oil, when neither of these can be procured. Fmb
bog's lard melted, and mixed with a little salad oil, forms a
good softening ointment for horses' Iteels that are sub}eet to
cracks.
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
to more important remedies- Honey is sometimes added tO a
solution of alum, as a lotion for the tnouth, wl>en it is inflamed

Honey is nutrition* and rather laxative, and may be ocea-

HOP. — Ilumulus. A decoction of hops is a good ttomachie
bitter and anodyne, (KMstssing a weak narcotic quality. Il
forms also a jiood anodyne and discuiient fomentation.
HORSE- HADISH. — /irmoraeia. The root of horse-radish,
when fresh, is n powerful stimulant. All its virtues may be ex-
tracted by disiiiling the root wilh water or spirit; in which
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
water, it is capable of blistering the skin.
HYDHAGOGUES. This appellation is given w thos*

INFUSIONS. — JnfuM. Medicated liquidii, made by pour-
ing Ixiiling or cold water on any vegetable or medicine, whose
virtues it is enpable of extracting. When the medicinal prin-
ciplea of a vi-geiabte are of a volatile nature, and liable (o eva-
porate by boiling, they are extracted by t>eing steeped in hot or
cold water. The liquid thus obtained is termed hot or cold in-
fusion. Chamomile flowers, peppeiminl. and other aromatic
herbs, are to be infused in hot water; logwood, guaiacum, and
l>ark, require (o be boiled, the latter a short time only, the two
former much longer. (See DEcocriON.) The menstruum of

of nature in many marine plants. Its properties are Mtimulantt
and its chief action seems directed to tlic abwrbcuUt which it
excites in a very high degree.
Iodine i» now extensively employed by scientific vctcriitariaiu.
Itt* thus dettcniwd bv Mr. Morton: —

Sniend uie anionj^^t veterinarians, I have little doubt but tbat
ley soon will. Iodine is obtained from the mother- water, aflrr
tl>e procuration of carbonate of soda from kelp. Its action is
of a stimulant to glandular structures, and the forms in «i
it ia employed externally are those of a liniment and ointim
Internally it may be given in doites from five to ten grains twice
in the day. alihoiigh there are ohjeetioiis to its being adflii*

Diniodidt of Copper, — Mr. Morton has formed a new com-
pound \>y the chemical union of iodide of potassium and sul-
tihate of copper, two ounces of the former ajjd four of the
Micr, with a pint and a half of boiling distilled water; the
copper to be dissolved in two third;-, and the iodide in one third
of the water. When cold the solutions are mixed, and the
precipitate falling i« to \k separated and pulverised.
TItr action of thi« medicine is that of a tonic and a stimulant
to the aboorbcnt i>iy«tem. The <lose from I to 2 drs. daily, com-
bined with vi^etable tonics, and sonictinu-s small doses of can-
llmrides. It has been given successfully by Mr. C. Spooner and
Mr. Daws for farcy, and is to be recommended for nasal gleets
and glanders, its double action being >o desirable in these cases.
1 have employed the sulphate of conmr, rubbed down in a
mortar with iodide of potassium, witli success in cases re-
sembling glanders, giving vegetable tonics at the same time.
Mr. Morton also recommends, for the «imc purpose, the iodide
of iron, a chemical combination of iodine with iron, in doses of
one or two dnichnis. — Eo.] •
IPKC-VCUAN. — JjMritciiaTilia. Ipecaeuanha is sometimes
empioyinl as an t-xpecioraiit in chronic cough, and asthmaiie
airwiions, and I believe with good effect when joined with
squills, aminoniacum, 8tc. (See Expectorants.) According
to Vitut, from half an ounce to an ounce given to a horse, makes
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;

IRON. — Ftrrum. This is one of iiie most abundant me>
tullic nroiluciions of nature; its ores are fouttd in almost eveiy
part of tlte filnbe in the soil and of^en in t)H.> water, and as a
L ronntiiuent of vegetable and animal bodies. The only prt-
I paraiion of iron commonly used in veierinarv medicine ri
I sulnhate of iron, or salt of steel, a useful Ionic in doses of two
' or four drachms.
JALAP, (lie Root. — Ipmmra Jalapa. In the human body,
I lite root of jalap is a certain and efficacious purgative ; and dwre
[ 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
obwrvetl lltat in a very Inrge cjuanlily it occasions sickness, and
aome di^ni' of purging, though it* eRects in this way are by no
tiinns »ulficient lo induce any one to employ it as a purgative
alone.
I onoe gave eight ounces of jalap at one dose to n glander«d
horse, that was in other rrnwcts liealthy, and had not been
taking any other medicine: in about six hoiirt the horse ap-
p<iii'ed sick, and in juiin ; lie refused both food and water ;
during the night Ih- appeared to have had nunc sntall water;

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
FEiiHiruciKS.) James's powder is iiiKuIuble in water, and should
therefore not be administered in a drmch. According to the

by the College of lliystcians to the compotiud of chlorim- and
lime, long known In tiie aru by the name of chloride of limr,
or blcucliiiig powder.
" It iit a vaitmble diMufeciant. hi order to uttdertiand iti
iiclion, it is necessary to bear iii mind tliat the fcelid gases gives
off during the decomposition of vegetable and aninul subUancrs
are mostly compoundi of hydrogen with certain bases. Wieo
chlorine is brought into contact with tlie^. it decomposes tlietn,
in consequence of the great affinity it baa for hydrogen, with
wliicb it unites, and sets the bases free.
" Mr. Yoiiatt, in 18i>8, and afterwBr<lfi Mr. Simpson, Mr. Hoi-
ford, and Mr. Kerr, tn the pages of the VftrriHarian, have drawn
the attention of veterinary surgeons to this valuable compound
in fistulous affections, open joints, canker, and in eases of grewt.
But it will be found serviceable in nuiny other dismses. To
Mr. Youatt wc arc in<lel)li-d for its introduction as a remedy tn
hoven in cattle, and lymuanilis in the horse, being given in
doses of from two to four drachms suspended in water. A solu-
tion of it. in the proportion of a pound to a gallon of walfr,
is recommended as un application for mange by Mr. Lucu
of Liverpool ; and in slight. attacks it will be found of service.
"This solution may be employed as an ordinary excitant ol*
wounds, and particularly in such as have taken on unhealtliy
action. Ill fact, I feel assurc<l tliat the more tliis compouod it

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
bleucliing. It has been employed for fumigating giandered

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-

more safe and elTectual.* Mashes are a necessary diet, also,
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

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

Opium is broiij;ht to this country in chests from Turkey and

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\

mrc also u»kI. Opium it i^arded m bod, when it is either very
•oft or friable, of an iniensety black colour, or mixed witli manjr
impuriiiek.
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
neiicia], when joined wiih bark and ginger. Someltmes it ti
given with emetic tartar, and some cordial composition, with
good elTecl, and in tlits way it proves a good diaphoretic.

cess; but the ciTt-ct is not pennai>enl.
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.
The medium dose of opium ishalf a drachm, ton dmchm ; but if
given in the form of clyitcrs, which it sometimes in with tlte best
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*
cieiit, which liavf gi-nt*rnlly been joined with iwirl spirit of
nitre, and other eaniiiniiiivi--i. 'J'hc medium dun- of the tinc-
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*
ployefl exiernally, and is said to be almost as eflicacious as when
taken into [lie stomach, pmdiicing ila narcotic effects without
affecting the head, or causing nausea; but in llie liorse it is not
likely to be useful in this way. Of late years I have generally

' 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.

POISONS. These are nouc«d iu a Materia Medica for the
purpose of allowing the means we are acquainted with of coun-
teracting their baneful eflccis. Poisons are of three kinds, vis,
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-
nesia.* The same means may be employed to coimteract tlic
etfecEs of siiblimate.'f- When there is much purging, give linsL-ed
tea, tripe liquor, or thin gruel, or gruel made of arrow-root.
Such iniinenxe dosca of sugar of lead have been given by wav of

that flows down tlie hill seems to be impregnated with lend;
for at sucli times it overflows certain meadows, and on the wuu-r
retiring these meadows have poisoned horses, cuttle, and other
animals. This fact is well known in the village and its neigh-
bourhood ; and animals thus poisoned are Kiid to tie mimUretl,
or tnoimitreil. Animals very seldom recover from it, though they

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

quired, as wc cannot be accurate in respoci to quantity utien
the decoction of poppies is employed, li has been a^ert&ined
that the anodyne or narcotic qualities of opium are diminished
by long boiling, and that the extract of poppies, however care-
fully prepared, is very inferior in every re«itecl to opium. No
licwitation, thon-fore, should be felt in pnTcrrlng opium to the
extract or decoction of white poppy )>ead*, whether it be wanted
for a clyster, a drench, or a fomentation.
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.

however, a strong and very effiencious caustic, when dissolved in

the wood of the latlei" are generally employed in medicine-
Both of them are powerful biltei'6 and extremely efScacious iu

ing tlie slate of excrement when none can be found about ilie
litter: wbetlter it be soft, hard, or slimy. The only method of
knowing whether the urinary bladder is full and distended, or
empty, is by introducing the hand into the straighi-f;nl, where
the bladder can be easily tell, as it lies immediately beneath the
gut next to the belly or abdomen. The nails should be pared

IIHUBAHB ; the Root.— Rheum Palmaban. This isa native

with the same care as that imported from Turkey, which liaj a
IM-culiar aromatic odour, atKi a bitter, slightly astringent, ai»d
subacid taste; b easily pulverised, and produces a powder of a
li^dit yellow colour. Hhubarb is sloniachtc, astringent, and pur-
gative, according to the dose in which it is exhibited. It is no\,
however, emploA-ed for (lie latter purpose as a horse medicine,
but is not unlrcquenlly adininislcred as a sloniacbic, in doses
from half an ounce to an ounco, combined with aloes and
ginger.
ROSEMARY. — Rogmarintu officinaHs. This plant is cul-
tivateil in Brilaiti, but is a native of the south of Europe,
Oreec*?, and Barbary. ti flower* in April and May in this coun-
try, and tlie leaves and flowern yield nn essential oil, which appears
to contain camphor, and which is frequently uwd as an embroca-
tion for strain.1 and bruiM's, mix*.'d with rectified spirit and soap.
'I1iis tnixiure is nearly the same an the celebrated Opadeldoc ; and
by the addition of camphor it becomi-s tW- same thing.
ROWELLIKG. An operation often performitl in veterinary
practice. It comiHts in nmktng nn incision in the skin, about
an inch in length, with n pair of Mhort and strong-bladcd ecissore.
The finger is then intmduceil, in order to M-|)arate the skin
from tlie subjacent parta all round the incision, that the cavity
may contain a circular piece of leather about an inch and a lulf
or two inches tn breitdiV\. &«(or« v\\i& l«atJirr is inlroducctl, a
AND PKARHAOOPIEIA.
SQ9
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

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.

as a detergent, and, when the proportion is considerable, makes it
a iirong cauitic. A solution of sulphate of copper in vinegar, or
vinegar and water, mukc^ a good wash for the foot rot in sheep.

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
ounces of sulphur an equal quantity of antimony, which pro-

While lite hiirKe is taking tunics, j^i-eat iitlfiiliun i^iould be paid
to his diet; and it vrmild not 1m> going too far, I believe, were I
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
mineral tonics, so well known as powerful {joisons in the human
body, preferable to those oblainetl from llic vegetable kingdoni?
In tbe fii'st place they are considered iis tlic only medicines
capable of curing tbo glanders and farcy, and are llicrefore pre-
scribed for tho«c diseases. I have never seen a single case of
glanders permanently cured, either by araeiiic or blue vitriol,
notwithstanding tbc numerous trials I have witnc«4ed during a
period of more than twenty years. Farcy has certainly disap-
peared in many instances white taking itMse mi-dicim's, hut iil

colic, or ]{riprs; and, when combined with camphor aud other
Ktinuilant^ tnitkes a f{ood onibrocaiion for indurated swellings,
Htraiiis, and brui>K«.* When properly mixed with mustard, it
Ibrinx an embrocation llinl has been found serviceable in coun-
teracting tn/CT^in/ inflammnlion. I have si«n it applied to ob-
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
large <lHses it generally act» a* a purgative, c^pi.'cially when iho
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
urine, wbeiviw six or t-ight dmchina will siiniulate the bowels,
and purge vriiliout atfeciina; the urinan,' organs, or only in a
moderate degree. It is said^o be almost a specific remedy for
tape worm, iii the human Imdy, always discharginft it dead ; and
in obstHiate coiistijuition, de(>ending on afiections of the brain,
Dr. Paris says he lias several tim«s witnessed its bon<'fieiiti
cHects.
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.

WATER. — Aqua. Much has been written respecting the
diilerent qualities of water, some having been con»i<l<;red as very
injurious to hoi-ses, while olhent liave been said to promote
heultli and condition. Dr. Bracken thought hard or ptipip
water hiibic to produce the gravel or stone; and other authoi'H
'have hud xtiU more whimsical notions on this subject. It
appears probable that liuiispari'nt and sweet water, tliat is, such
as is most gratel'id to man, is most wholesome for horses, whether
it be taken from a well or from aiw other situation. The ill
vfTecis that have somelimes resulted Irom drinking certain kindii

of water may dqiend upon iu beiDg di-ai)k too Urftirly, or ul loo
eold a tvmpcrnluiT, at n lime when ihe Ktoniacti was nut in a
contlition for Receiving lo much, or upon its being so ill-tattcd
lluit iIm' Imrsc dties not lake a sufficient qitaniiiy lor the purpoMi
of iti^aiilion ; or, if he doe&, il may crcalc that (k-gror of iiauKroi
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.
