tbe Uorse, n-bicb has bcon prepared with great caro by a nuiuber of tlio 
tnost eminent meiubereof tboxotcrinary profi.'.sskm in tlie Uiiiteil States. 
The prtHluction of u wctrk of tUis clinrauu^r is a task of such masnitiuie 
ttiat it could not be anilcrtaki-D hy any one man with ft prutipect of its 
early completion. It was deemtHl heat, tlierpfure, to ilivule tlie nubject 
into sections and to plaoe the pre)>arjtion of each section in tbe liaitda 
of a veterin»ri»n wIiokc practical experieaoo and reputation would in- 
eurc a Yaliiable coutributiOD, By adopting tbis plan tbe coQt«at8 <tf 
tbe vol ii [lie Iiave been made i-cady for tbe printer witLln a year (bom 
tbe time tbe work was begnii. While, on account of tbiit mctboil of 
prcpamtiou, tbiTL- may not bt: Quito tbo satue uniformity of style and 
treatment wbtch vonid be ex))ccted io a rolame writtoo by a Biaglo 
BUttior, it ii« bopdl tliat tliis will nut be roinul olijeetionHble, and tbe 
Bi»ec4ty completion and the cu-uiK.-rntioD of aiitbors irbo bare given 
special attention to tlieir snbjcctd will prove of crcnt ad%'aiiUiK0. 

Tbe need of a work on the diseases of the boi^e, whi(;h eoubl be dis- 
thbnied to farmers as a safe and scientinc ijnide in tbe treatment of 
tlii.s Hpccirit of our dome.t licit ted niiiiuals, either wbcii afl*oeted with 
elJgbt disoixicrs or serious illness, has long beeu felt. Tbia obnous 
waiiiba«l«d totlieprepamtioaof the present ("oluiuo, which isdeslfinod 
ax the iJrst of a wrJe-s to cover the diseases of all varietii'S of farm ani- 
mals. The vf riter would not advlso the fariucr iu oi-diuary circumataiiccs 
to disjicnse irltb bis vetcntmnao, any more than be wontd adTi«e him 
to treat tbe diseases of bis own family, to miinnfaeture Iiis own fnrni- 
lore, or to l«> bi» own blac-ksmilii. There are, however, only too many 
caseA in which tbe veterinarian can not be procured in time for success, 
If at all; and, conneqacntly, the firmer wbo knowd or Iins tbo rueansof 
leiiniing tho nntnreof ibc dj.scHse and the proper treat meat will be able 
to save an animal nlien otherwise be would lose one. It is eoniiuuii for 
ititelli^'nt people to lau^'h at thoideaof attempting to make every man 
bill own doctor, his own veterinarian, or bis own cnrpentcr, and in »□ 
ideal condition of society no doubt this would be abaunl. But under 
the conditions wbicli actually obtain on onr farms, the farmer who can 
QM tools, if but ankvranlly, oflCD (Inds it ostrcmely couvcuient to 
tern iw>rar illy iiittrp the foiietions of the carpenter; and ho also finila 
that in many ciLses he must treat bis ailing animals or allow tht-iu to

better for the atocU-ow^uer to have at Uisvomraand theiuLviceofTctorl-

oftt'u barbamns metliotls of treatmcni wbluh have Ixhiu handed down 
by tradition from tb« empiriciam and i^orauce of long-past ngcst 

It is an extremely difflcalt matter to divost nioditfal HtiTatnre of taahri 
niKal ternoB iind expresRioiis more or less iiiwrniprflieiisible to the gen* 
ernl reader. This haa made acii^nCiSo medicine a seated lioolc to the 
maaaea of onr pfA^ple, and there is do subject of irliicb tliey are mort 
ignorant. An attempt lias been made in this work to present the vaa,r 
ler in hb simplo language as possible, and wliile Home of the aatbors 
liava liecn more happy than othem in this rcHpecti it is believed thai 
no {nrat dillicuUy will be met with ia any of the articUit. 

\vtiile thpsiibjcoi baa been treated in laiiguagu of a more or lc» 
popular atyle and the book is intended aa a guide to the farmer, ita in- 
trinsic acitutiflc valuoehoitid not be entirely tost sight of. In tuanf 
rcsi'cela it is a notalde contribntion to existing knowledge, and it wiU 
be j)ii2ed by the vetertnarinu not less than by the farmer. Na doubt 
tben^ are aome defects iu thia firat edition which the experience of ttia 
future wilt enable us to remedy, but aa a whole the book is one vbtch 
can not fad to be of Immease Her\-ieo in educating bora*; owncnt and in

grenier part of the Bnbjecte being aeleetcd by Dr, Cooper Curtice. In

are intended, chiefly, to net Inc.-illy npon the iiionlli mid tbront. They 
are given vitb a wooden itaddlu or strong long-baiidled spoon. 

When bulls aro to be given we should obijcrTo tbo following direc- 
tious: Insbapo they sbonbl Iw cylin<lrio4i1,of the size nbovo mentioned, 
and soft enough to bo easily compressed by the Augers. If mado round 
or egg-sba-ped, if too long or too hard, they aro liable to become fixed 
in the gnltft. find canKccboliin^. BuIIk may Xtv. given nilli the '^bnlling- 
gun" (obtainable at aoy vctcrioAry instnitueut maker's) or by the baud. 
If given by tbo band n moutb speculum or gag should be used to preveat 
the animal from biting tbo hand or rrnHhitig the ball. Always loosen 
tbe horse before attempting to give a Wllj if tied bo may breiiU liia 
baiter and iojnre bimeelf or the ooe giving tbe ball. With u littlo 
practice it is mncb easier to give a ball without the moutb-gag, as tbe 
borse always Cgbts more or less against having Iils mouth forced open. 
The tongue must be firmly graspeii with the left buml and gently pulled 
forward; the bull, slightly moistened, is then to be placed with the tips 
of tbe Angers of the right band ns far back into the mouth as poftaible; 
us Ibe tongue is leost'ued it 1.^ dniwii luu^ into the mouth and eitrries 
tbo ball backwanl with it. The month should be kept closed for a 
minute or two. Wc should always have a pail of wat«r at band to 
offer tbo borso after balling. Tliis precaution will often prevent him 
from coughing out tbo ball or its beeuniing lodgetl in tbe gullet. 

It is, very often, impossible to get balls x^")pc'''y made, or to induce 
owners or nttcmlants to attempt to give them, and for these reaaous med- 
icines by the moutb are mostly given in the form of drenehes. When 
medlciao is to be given as a drench we must becarefbl to use enough 
water or otltothonmgbly dissolve or dilute it; more than this makes the 
drench bulky and is unnecessary. Insoluble medicines, if notirritontor 
eorniKivp, may be given simply saapended in water; the bottle (o l»e 
well shaken immediately before giving the drench. Tbe bottle used for 
drenching purposes should be clean, strong, and smooth about Its 
neck; it should be without shoulders, tapering, and of a size to suit 
the amount to bo given. A borii or tin bottle may bo Ijetter, in that 
broken by tbe teeth. If the dose Is n umall one

of the face should be horizontal, or only the Ica^it particle higher. If 
the bead is dmwa too high tbo animal can not finrallonr with ease, or 
even nitb tuifety. (If this i.t doubtful, ju.it till your mouth vritb water, 
thruw back the bead aa far as possilile, and then try to sivallow]. The 
pvrsoQ giciug the drench should Kinnd on some object in onler to renoli 
the horse's tnontb, on » Icrel, or a little above it. The bottle or bom is 
ktben to be introduced nt the Hide of the mnutb, in front of tho niolar 
^Icctb, iu an upward direction. Xliia will eaase the horse to opco bis

baa t«(keD all the drench. If coughini; occurs, or if, by Auy mishap, the 
Ibottlo should bo crushed in tbe mouth, lower the head immodiatelv. 

Do not rub, pinch, or jmund the throat, nor draw out the tongae

ofiencrdobnrm. 

Dreaeka mntt nrrrr be i/iren through the wow; ibey are liable to

Cattle are easily drenched by simply holding them by the nose irjlh the 
k'ft luiud, while the medlciuu is [wuied into the muiith with the right. 
Balls are not to bo ^ren to cattle; they often become iml>edded in tbe 
freat miiss of food iu tbo Htomach and net tardily or not at nil.

by InmilBatiou, inhalation, and nasal ilourhe. Intvffiatlon consists of

as in also mc<1Icat«d 8t«an) or vapor. Of tiie gasos used w« may men* 
tioB, ati the clii«f ones, sulphurous acid gas, and occitsioually cUorine. 
Tb« aaimal or animnlB uro to be placed in a tiglitbuildiug, irherotbeM 
gases are generated, until the atmosphera is safflcicntlf impregnated 
with t!iem. Vulatilo Ditxllciiit-H, an Ibeaiia-Hilietic«, (etiier, chloroform^ 
etc.)} &re ouly to tie given by the attendtog surgeon. Medicatt'd vapors 
aro to Iw inhaled by placing a bucket containing hot water, vinegar and 
wntor, scalded hay or bran, to which carbolic acid, imline, or other 
rnvdidacH bavu becu added, iu tho bottom of a long grain tiag. The 
horae^s nose is to be inserted into the top of tbe bag, and he thus iu- 
haloa tbe "modicat«d steam." Care icnst bo taken not to have this 
hot enough to scald the auimal. Scalding bran or bay is often thu 
inhaled to favor discharges in sore throat or '• distoiuiief." 

The nasal douche is employed by the Teterinahan in treating somd 
local diseases of tho nasal cbambora. Special applianoes aud profes- 
sional knowledge are iifcessHrj- when using liquid medicines by this 
nielbod. It in not oftuii resorted to, eveu by vetenusry surgeons, sines 
the horse, as a rale, objects very strongly to this mode of medication. 

(3) By tux. Skin.— Medici ncd are often administered to our balr- 
covered animals by tJie skiti, yet care must lie taken in applying somo 
Diediciues, as tobacoo- water, carbolic acid eolations, etc, over the eutlre 
body, as poisoning aud deatb folloif in some instances from absorption 
through the akin. We must also cscrciso care, and not apply poisonous 
meiliciites over very large mw or abruded surfuecH, fur the same rea- 
sons. For domestic animals medicines are only to be applied by the 
skin for loc»l pnriKisi'tt or disciuws, as latidunum, chloroform liniment. 
etc., for neuralgia. 

(4) Undkk the Sein— Hyfodebmio Method. — Ucdiciues are fre- 
qneotly given by the bypodermic syringe, under the akin. It will not 
be safe for any but medical or veterinary practitioners to uav this form 
of medication, since tho medicines thus givcu are powerful poisons. 
There aro many precautions to be observed; a knowledge of anatomy 
is indii«{H>nKiblL'. 

(5) By tui: KbotL'H. — Medioinea may be given by tbe rectum when 
ve can not give or retain them by the mouth \ wbeu wo want a local 
action on t*ie lui^t gut; to destroy the small worms infesting tlie large 
bowvts; to sliiiHilat*) tbe peristaltic motion of tbe intestines and cause 
evocuatiou; and to nourish tho lK)dy. Medicines an^ hero given in the 
form of suppositories, or as liquid iiijcctious — enemas. 

Suppontorien are conical bodies made up of oil of theobroma and 
opium [or wtiatever me<licine is iiidicateil in special oimcs), arid are in- 
troduced into the rectnni or vagina to allay irritation and pain of thi-M 
porta. They are not much used iu veterinary practice. 

Enemati, when givi^u for ubKorjitiou, should be small in quantity, 
neutral or slightly acid in rcitctioii, and of a t«mpemturio of from 90^ 
to 100° F. These, like foods given by tbe recluuj, should only be iu- 




18 



trodaoed after tbe last bowel h&n bnea emptied hj tbo hand, or by 
oupioua enemas of t«pid vater. Bneiuaa or clyetcra are moHtljr glren 
to aid tbe actiou of pbysice, aud idiould thon bp in quantities sufficient 
to dut^ud (be bowel andcaase tbe animal toejecl tbem. Simple water, 
salt and water, or soap aud water, in quaatitiett of a gallou or more, 
may be given every half bour. It is best that tbe borse retain tbem for 
Bomo little time, ae tbe liquid norvca to moiAtcn the dnng and faror 
a paaftage. stimulating enemas (tarpentine 2 oaaccs, in linsood oil 6

empttui the laat bowel, witfa tbe purpose of still farther iucreasint; the 
natural worm-like movement of the iDt«»tinee ami aiding tbe pargiog

leavtae roany j^pa, and continually checking tho disposition to nrite 
anyiliing like a full description as to cause, preventiou, and modes of 
treatineDt of disease. 

Thest! articles are addressed entirely to fanaers aud slock-nwiietB, 
and I mnst a.sk my prorossionnl bretiiron to IxMr this in tnind, uiieo 
dtgpoj«!d to co[iiplatu of a waul of scit!iitllit.' tivatuieut of the stibji'vts. 

Water.— tt is generally held, at least in practice, that any water that 
nock uQu l>e induced to drink is sufEcicutly pure for their use. This 
practice occasions tosses that vould startle us If statistics nero at baud. 
Water that is impnrn from tlie presence of decomposing organic mat- 
trr, such as ia fuuud iu wells and punitn in cloM! proximity to uiuuuro 
heaps and cesspools, ia frequently the cause of diarrhea, dysentery, 
and many other diseases of stock, while water that is impregnated with 
diOVrcui poisons, and coniaminateil with speclllc media of contagion, 
prodacea death in very many instances. 

Coaaidoring first the quantity of water required I>y the horse, it taay 
be stated tliai ultima our animals have j>cce(>K to wiiter continually they 
neverdrink to excess. Were the bone subjected to ship-voyages, or 
•ny other circumstances where he must depend npon liis attendant for 
tbe snpply of water, it may be roughly stated that each horso requires 
a daily average of about 8 gallons of water. This will vnry some- 
wliat upon the character of his food ; if upon green food, less water 
will be needed tbuu when fed upon do* bar and grain.

The time of KiviDg vater sbontd be carefully studied. Atf««t, th« 
boree stinulil receive wut^r at leiiBl tbrve tittu-n a day ; vhen at worlc, 
mora ftcqueatl^r. The rule here alionld be to give iu Bmall quantities 
and ofteo. Xhero U a popular fallacy that If a horse ta warm be 
Khould not be allowed to drinlc, many claimiDg that the flrHt Hwallow 
of water "fouiidern^ the animal, or pniduiMu colic. This is erroueoua. 
2Io matter bow warm a horse may bo, it ia always entirely safe to allow 
liim f)x)m six to t«a Bwallowa of water. If this is gjveu ou f^oing into 
the stable, he Hlioiild be given at once a pnnnd or tn-o of hay aud 
allowed to rttat ahoiit an hour before fcediut:. If w»bT lie now offered 
liiu it will in many casee be refased, or at least he will driiik but spar- 
ingly. The danger, then, is not in tho '* flret swaJlow "ofwater, but la 
due to the f'xoKWsiv-e quantity that the animal will take whcu worm U 
not rmtrainod. 

Water should never be given to horsea when it ia ice-cold. It m^ 
not be riiM.'4'SKury to add hot wat«r, bnt we should b^ (■artful in placing 
wntertroughs aliont. our baruH to have lliem in eiich position that the 
aau may shine upon the water dnriug the wiuti-r monnngs. Water, 
evea though it be thus cold, seldom prudaces serioutt trouble if the 
horse has uot been deprived for u too great length of time. 

In reference to tho purity of wat4sr Suiitii, in his "Veterinary Hy- 
gicuo," claaiies spring, deep-well water, and uplaud surface-water aa 
wholesome; 6lore<L raiu-wator and surface-water from cattivated land 
as atupicious; river water to whieh sewage gains access and shallow- 
well wnt«r as danyerotu. The water that is uited for drinking purposes 
for stock so largely throughout some States can uot but be impure. £ 
refer to thoee sections whi-rc there ia au impervious clay snbsoil. It 
Is the custom to s<H>op or hollow out a large biusiu in tho different pas- 
tures. During rains these basins become filled with water. The cli^ 
aubsoil being almost ioipervioUH acts as a jug, and there is no escajie 
for the water except by cva)iora1iou. Such water is Htugniint, but 
would ho kept companttrvely fresh by sub»eqnent rains were it not for 
the fact that much organic matter is carried iuto (U)->»e ponds by snr* 
face drainage during each succeeding stxirm. This organic matter soon 
nudergocs decomiH>si(ioii, aud us tho result wo find disea.-scH of dtflTer- 
eot kinds much more prevalent where this water \» drunk than whcrs 
the wator-sup|)ly is wholesome. Agaiu, it must not be lost sight of 
that stagnant surraoe- water is ninch more certainly contaminated than 
is running water by one diseased animal of the herd, thus endangering 
the remainder. 

The chief impurities of water may be claaaeil asorpanicand inorgania. 
The organic impurities are either animal or vegetable substauceA. 
The salts of the mdals are the inor^tiic impurities. Ltmo causes 
hardiness of wster, and occasion will be taken to speak of this whoo 
d«»L'ribiiig tiitti-Htiuid coiicreiiuus. Halls of lead, iron, and copper are 
oIhu frequently found in water, and will be rererred to hereafter. 





About the only exainiaatioD of vaXeit that can h& miule by tho arer- 
•ge stock raiser is to ob««rre it« taste, color, smell, and clearoess.

with merely (nvinK * fo"* ^*^^ oa to tbedifii-rcnt kinds of food, prepa-

proper fe«^ditig and watering will donhtlesa account for orer ouebalf of 
the digestive diaordem met with in Uie horse, and hence the reader can 
not fail Co see bow very important it is to have some proper ideas oon- 
c^rning these subjects. 

Kindg of food. — In this country horses are fed chiefly npoii bay, grass, 
roots, oats, com, wheat, and r>-o. Many think that they could he fed on 
lti>rhiug else. Stewart, in "The Stable Book," gives CLe following ex- 
tract from I^odou's Bncycloiiedia of Agriculture, which is of interest 
at tbis point:

Sniitli's Veterinary llygiene. 

Wc caa not, however, leave aside entirely here a constdoration of tbA 
digestibility of foods; and by this we mean tlie rL'adiuess with which 
fowls undergo those changes iu the digestive canal tliat fit ttiem for 
ftbsorption and deposition as integral parts of the animal economy. 

Tho age and health of Ifan animal will, of coursi-, modify the digestl- 
btUty of foods, as will also the mauner and time of harvesting, preserv- 
ing, and preparing the foods. 

In the bonuf digi-.stion tukes place )>rinnipally in the Entestiuea, and 
ben, as iu all otlier animals aud with all foods, we lind that a certain 
part only of the provendi:r ts digested \ another portion is indigested.

with bulky, iuimti-itiouH food immt^diately before going to labor. TIis 
small stomach of the horse would seem to lead us to tbe eoncluBion 
that tliirt animal Kliiiald be fed in Kmnll quanlitirs and often, whieli, ia 
realily, should be done. Tbe disproportion between the siio of tbe

give him an alooholio stimnlant on going into tbe stable. A small 
quiuility of bay may thru be jrivrii, but his grain should bo witbbclil 
for one or two hours. Tbese same remarks will apply with equal force 
to tbe borso that for any reason fans been fastiug for n long tinio. After

will it answer lo feed bim entirely npon coneentrateil food. Bulky food 
must lio fnvcii tu tletatD Ute graius in tliclr pasnngc throniih the lutes- 
tfnnl tract; bnik also favors distention, and (bus nuHilmnlcally aids 
altsui'iilion. To liorsos that do slow work for tlui grwitor part of tho 
lime, choppetl or cut liay fed with crushed oats, i;roanil corn, etc., ia 
tbo bt-Kt manner of f^i-diuf;, as it given tliu nM)uircd bidk, saves time, 
and half tlie labor of feeding. 

Sudden ckangt* of diet are altfatfs dangerotis.— "WUeu deaironB of chang- 
ing the food, do so verv gnidii.tlly. If a horse i» accnsloiued to oatx a 
sudden ctiunge to a full meal of curu will almost always sicken liim. If 
«Q merely intend to iticteaso tbo quantity of the v«ual feed, tlii9 again 
must liodone gi'adiiaUy. Tho qiiantiCy of fnod given ninsit always be 
in proiKirtioQ to the amount of labor tu be performed. If ahorse is to 
do less work, or rest entirely from work for a few days, see that he re- 
ceives less feed. If this vhb observed oven on Saturday uj|;bt nnd 
Sunday there would befewer cHsea of '^Monday moruingsicknesH/'snoh 
as mlics and tymphaugitis. Foods slionid also bo of a more laxative 
nature when the horse la to staitd fur sonic days. Aboro all things ive 
aid nvoid feeding ninsty or moldy foods. Those are very fnxiueut 

,nsc6 of dit;ea»e of different kinds. Liuig trouble, as bronchitis and 
^heaves," often follows the nse of snch food. The digestive organs 
always suffer from moldy or musty foods. MuKty bay in grnrrully con- 
ridered to produce disorder of the kidneys; and all know of the danger 
to pr4>f;nant animals from feeding upon crgotized grasses or grains. 

Leaving thr.sft somewhat general con.sidemlions, I will refer briefly to 
tbo ditfercjiL kiudK of fiimls: 

Aay.— The best bay for horses is timothy. It should be aboat ooe 
vear old, of a greenish color, crisp, clean, fresh, nnd posseuiDgasireett 
plenKant aroma. Even this good Imy, if kept fur too great a length of 
time^ loses part of its nuuriHlinicat, and while it may Dot be positively 
injurious, it is hard, dry, and indigeslibleu ^*ew bay is dllBcult to di- 
gi>st, produces much salivntiou {slobbering) and occasiunuliy purging 
and Irritation of the skin. If fed at all it shonid be mixed with ohl hay. 

Second crop or a/icrmalh. — This isnotujoHidt^redgood buy for bonuM, 
bat it is prizetl by some faruers as a good food for milch cows, they 
claiming that it increases the flow of milk. The value of hay depen<la 
upon llie time of cutting, as well as care in caring. Hay should be 
cnt when in full dower, but before the seeds fall; if lefl Umger, it be- 
oomoa dry and woody and lacks in ontntion. Ab eiMDUal point in 
uakiDg hay is tbnt wlien the crop is cut it shtnild remain as abort a 
time as jwtutible in the field. If lefl too long In the sun tt loses cutnrf 
flavor, and dries or wastes. Smith asserts tbat one boar loore tlioti i* 
ncoeosary in the sod eaaeee « less of Ifi to liO per eeuL In the feeding 
valoe of hay. It is irapotiaible to state any flxcil time that hay must 
hare to cure, this depeoding, of oouac, opoa tlie weatlwr, UiIgIluobs at 



tbo crop, and mnny otber ciroumstaiuws ; but It in veil known that in 
ordrr tn |in.'.serve tlie color ami aroma of liay it slioiihl be ttirueil or 
tcdikt) frequently ami cuml a» quickly a« pttntible. On tlio other hantt, 
bay spoils in ttie mow if liarvestt'd Uxi green or when not sntllciently 
dritnl. How-burnt bay iinxliiL'As disorder of the kidneya and bowels 
and tuuisea the horse to fall off in condition. Mnsty or moldy liay ha-s 
often bf en eaid to proclutv that p«valiar disease known Tariouelj' M 
oerebroBpinal nicniiigitiSf pntrid sore tbront, or cbokinff distemper. 

Tbt> avuragft horHi-, gfttitig Krain, should tie Hllowe<l Trom 10 to 13 
puiiudKof good hay a day. It fa a mistake of many to thiuk that borsea 
at li(.'bb work can be kept entirely oo hay. Sucb horsea aoon become 
pot-bellied, fait off in flcsli, and do not thrive. The aamo is true of 
<io1t«; nnlf>i).i the latter are fed with some grain they gn>w up to l>e 
long, lean, gawky creatures, and never make as good borees as those 
accustomed to grain, with or in addition to their hay. 

Straw. — The straws are not eiteasivoly fed io this conntiy.ftud when 
used At all rbey should be uut and niised with hay and ground or 
crnsboil grains. Wheat, rye, and oats straw are tlie ones most nsed, 
and of these oats straw is most easily digcslefl and contains tlie most 
oonrisbniuHt. Pea iitid bran straw arc occasionally fed to horac^ tb« 
pea being preferable acconling to most writerH. 

Ckaff. — Wheat and rye chaff should never be nsed as a food for 
houses. Thp beanis frefiuently become lodgtil in the tiiouth or throat 
and are productive of more or less serious trouble. lu the stomach and 
intestines they often serve as the nucleus of the "soft conLTCilous" 
which are to be descnl>ed when treating of obstructions of the digestive 
trncL 

Oat ebaff. If fed In email quanttttea and mixed with «at bay or corn- 
fodder, ia ver7 mueh relished by horses. It la not to t>e given in large 
quuntities, h.h I have repeatf^^lly witnessed a tmnbleKoiiie and somelitnes 
fatal diarrhea to follow the practice of allowing bortsca or cattlu trtt ac- 
oeea to a pile of oat chaff. 

Oraiiu. — Oats take precedeneo of nil grains na a food for horses^ as 
the iogredieiits necei^'uir}' for the complete nutrition of the body exist 
in them in the best proportions. Oats are besides more easily digested 
and a larger proi>ortjou abrtorbod and oouverted into the various tissues 
of the body. Care iiiiiMt Iwtiikeii in selecting oats. According to Stew- 
art the be-st outs arti one year old, plump, Kbort^ bard, vleau, bright, and 
sweet Xcw oats nre indigestible. Kiln-dried oats are to be reibsed 
as a rule, for even though ongi'ially goo*! this drying process iujares 
them. Oats that Itavf^ sprouted or feritienteil arc iiyurious an<l should 
□ever be fed. Oats ari> to be given either whole or cnished ; whole in 
the minority of instances, crushed to old horsea and those having de* 
fcctive tec^Ib. liorses, alno, that bolt their feed are best fed upon 
crushed oatA and out of a mauler large enough to permit of spreading 
tbe grain in a thlu layer.

The average horse requires, in addition to tUenltowance of hay above 
spoken of, about. 13 quarts ofgoorl oatti daily. Tbo l>est onta are tbou 
oat about one K(^ek before being folly ripe. Not only is tbo grain riclier 
at this time in untrttive Diat«ria!8, bat there is algo le&s wa«te from 
"scatterinfr" tbao if left to be'Come dead ripe. Moldy oats, like hay 
and straw, oot only produce serious digestive disorders, bob have beeai 
tbe uDiloabted cniiRC of outbreaks of that dread disease in horses, 9M 
ready referre^l to, ubaracterized by inability to eat or drink, auddea 
paralysis, and death. 

Wheat and rye. — These grains are not to be used as food for horeea 
exoepC in small qiiitnliticH, liruiseilorcrualipd, and (eti mixed with other 
grainu or hay. If fed aloue, in any fousiderable quantities, they are 
almost ocrtatD to produce digestive disonlers, larainitis (founder), and 
similar troubles. They should m^ver eotitttitate more than one-fourth 
of the grain ailowanoe, and should always be ground orernshe<l. 

Bran. — The bran of wheat is the one xaoul used, aud ita value iis a 
feeding stuff is variously estimated. It is not to be depended upou if 
given alone, bnt ni:iy be fwl with other grains. It »er\'o» to keep the 
bowels ojien. Sour bran 19 not to be given. It disorders the etomoch 
and iutetitiues aud way eveu produce seriouu results. 

Mahe—Corn. — This grain is not suitable as an exolnsive food for 
yontig burses, as it is delitncnt in salts. It is foil whole or gruumL 
Com oil the 00b is commonly used as the food for horses affected with 
•> Um[>a().^ If the 00m is old aud la to be fed Id this manner it should 
besoalceil in pure, clean water for ten or twelve hoars. Corn is better 
given gruuud, aud fed in quantities of froiu 1 to 2 iiuarts ul a meal 
mixed with crashed oat« or vbeat bran. We must be very particular 
in giving com to a horse that is not accustomed to its use. it must 
be oommL-uix-d in Hmall quuiitjtii^ti aud very grailually inereaiwi]. I 
kuow of DO grain more likely to prodnoe what is called acute indigea- 
tion than coru if these directions are not olworved. 

tAn*eed. — Ground liusec4 is occostonully fed with other foods to keep 
tJie bowels 0[u^u and to improve the condition of the skin. It is of par- 
tiuolar service during couvalescuuco, wUeu the bowels are sluggish in 
Ibelr acCioD. Unseed tea is very often given io irritable or inttamed 
conditions of the digestive organs. 

fiuofjr — I'o(atoa. — These are used as au article of food for the horse 
in mauy seiitionB. If fed raw and in large qoantitioe they often produce 
indigeetiOD. Their digestibility is favored by stemming or boiling. 
They poottess, in common with othur ruutM, slight laxative pru|N*rtJes. 
BorU.— These are not much used as food for horses. 
Oiirrott. — These make a most excelleni foiwl, particularly during sick- 
iiesa. They improve the appetite aud slightly increase tbe action of the 
bowels and kidneys. They iio.ssess also certain ultenitive profKirties.

PBCrAltATIOH OP FOOWj. 



Foods are prepared for feeding for any of the following reasons: To 
reuder the food more e.isily eaten; to make it more digestible; to 
economize in aioouut; to give it some dcw property, nod to prcservo 
it. Wo have already spoken of tho preparation of drying, and need 
not revert to this again, as it only serves to preserve the diflerent foods. 
Drj'iug does, however, change some of the properties of food, ■*. &. re- 
movi-s the laxative tendency of most of them. 

Tho different grains ore more easily eaten when ground, crushed, or 
even boiled, ftye or irbeat should never be given whole, aad even of 
corn it is found that there is less waste when ground, and, in commoD 
with all grains, it is more ca.iily digested than when fed whole. 

Uiiy and fodder are eeonomize<l when cut in short pieces. Not only 
will the horse eat the Decessary amount iu a shorter lime, but it (vill bo 
found that there is less wnstc.and the mastication of the gniins (wholo 
or omahed) fed with tbem is insuretl. 

RefereQcebfls already been made to those horses that bolt tbetrfood, 
tuA we need only remark hero that the consequences of such ravenous 
eating may be prevented if the grains are fed with cut bay, straw, or 
fodder. Ixjug or uncut hay should also be fed, even though a ccrtaio 
amonnt of hay or stmw is cut and fed mixed with gn\tt. 

Oni» objection to feeilingent hay mixed withgronnd orcmnbed pniiiis, 
atid wetteil, must not be overlooked during the hot moatbs. Such food

they are slohberinf;, or where they evince pain in mastication, shown 
by holding tlu^r hend to one side while chvwing, the teeth shoald be 
carernlly txaminod. Jf, as is mostly the case, all these symptoms aro 
referable to sharp oonicra or projections of tho teeth, these ninstbe ro- 
moved by the rasp. If decayed teeth aro fouud, or other gcriuns ditB- 
cntty detected, an expert should bp called. 

7aofAocA«.— This is rare in the horse aud is mostly witneesed wh«i 
there is decay of a tooth. 1 hare observed It only in the molar teeth. 
Toothache is to l>o discovered iu tho horso by the pain expressed by 
him while feeding or drinkiug oold water, I have seen hor.ses affected 
with toothache that would suddenly stop chewing, throw the head to one 
aide, and sHglitiy open the mouth. They behave as though some sharp 
body had punctured the mouth. If upon examination there in no for- 
eign body found wo nmstthou careftilly eiamine each tooth. If this 
can not l»e done with the hand iu tho mouth wo can, in most- instances, 
discover the aching tooth by pressing each tooth from without The 
horse will flinch when the boki tooth is pressed upon, lu most oa«e« 
there is nothing to he done bnt the ext:-action of the decayed tooth, and 
this, of course, is ouly to be attempted by the veterinarian. 

There ia a deformity^ known as parrot- mouth, that interferes with pre- 
hension, mastication, and, indirecUy, with digestion. The upper ineia- 
ora project iu front of and Iteyond the lower ones. Tho teeth of both 
jaws beoomo uuusaftUy long, as they are not worn down by friction. 
Such horses expericuoo much difficulty iu grazing. Little can be done 
except to oooaslonally exumiue tho teeth, aud if those of the lower jaw 
become so long that they bruiwi the " hars^ ol the upperjaw, tbey must 
be shorteueil by the rasp or t»i»w. Horses with this deformity ehould 
never be lull eutireiy at pasture.

XnSBXSES OF THK HOUTB. 

Lampaa is the ttame ^xy^h to » B^cltiog of tbc mncaiis Tnotnbrane 
ooverio£ the hiird palaleaiul |)roJ«ctiiig in ii more or Ies8 promiuciit 
rillge immp<1iHt4>ly behind the upper incisors. Tbvre is no doubt bat 
tliiit iu Auuiu raro iii.sluncfs, iiikI purtiinilarly while teething, there is a 
eoQgestioQ and fiw«|]ing of tbi^ part of the roof of tho niouLb which 
may interfero with feeding. Id one tuatance in my practice I found the 
swi'llitig w) pxt»'n!*iv« (luit th« niiiroiiii membrane was cnnfilit lietween 
the frotit teetb wlieii the borso attempted to eat. Bboiild tliis exist the 
evollen parts nre to be eearified, beingcarefal not to oat deeply into the 
«trnctures. An nslTingent wash of nlnni water nmyaleo be IjenefiofaL 
Borniug of the Ininpaa la cruet and uiio«cc«sdr)-, and sbould nover be 
permitted, as it often cansea seriouH rcsnlts to follow. 

It ia quite a conimoo opinion among on-ncrs of horses and stablemen 
that InmjmH in n diKeave Uiat very frequently existH. In fHcrt vlienover 
a horse fails to oat, mid if be does not exhibit very marlied ttyniptonts 
of a eerere illness, tbey say at once " be has the tampas.'' Ft is almost 
Imponibte to convince them to tbo cootrory, yet in a practice extend- 
ing over fifteen years I have upver seen but two or tlinee wisea of what 
is called lampRs that gave rise to The least trouble or that called for 
any treatment whatever. It may bo pat dovu, then, as more u disease 
of the stableman's iioaginaiion than of the borse^s month. 

StotnatUis. — This is an iuDummation of the mucous luembrane lining 
ttifl moutli and is pHMlue^l by irritAting medicines, frMxls, or other 8ub> 
Stances. In cities it frequently folloirs from eating out ot asbbarrels. 
Tbe symptoms are evelling of the mouth, whlcb is also hot and pain- 
fal to the touch; there inn cnpiouH diKcdiarge of Kslivn; tliu ttiu»)na 
membrane is reddened, and in some cases there are observed vesicles 
or olcers in the month. Tlie treatment in simple, soft fcefl alone often 
being all that is necessary. In some instances it may Ite ndviKiible to 
nsea wash of chlorate of putasb, borax, or alum, about ouebalf utinve 
to a pint of water. Hay, straw, or oats shonid not bo fed unless 
steamed or boiled. 

Qlotntit, or Inflammation of tbe tongno, is very similar to tho above, 
and mostly exists witli it and is doe to the same cnuties. lujnries 
Uie tODgne may produce tbis simple indammationof its covering met 
brane, or, if severe, may prodnco lesions muc-b more oxieustve, sucl 
OS laceratioDs, abncOKKes, eto. These latter wonhl require surgical 
ti«atm«Dt, bat for tbe simpler forms of inflammation of tho tongue tba 
tKatmeot reoouimended for stomatitis shonid bo followed. 

Ptj/alitm or salivatioa consists in an abnormal and cxceju^ive Heer»- 
tion of saliva. This is often seen as a symptom of irregular teeth, in- 
flammation of the mouth or tongne, or of the ttse of sncb medicines aa 
lobelia, mercory, and many ntbrrK. Some foods produce tbis. a^ clover, 
uid putienlariy aeooud uropj forvigu bodies, as uaiJs, ubeui-chnil, and

Paraltfsin of the phtrgnx, or, as it is iMiuimonly t;a1ln1, " jiar.ilysis of 
the throat,'' is oneof tlie most stubborn di.iea.s-'-sur the horse that wu nm 
ever uilled to treat. A horse is suddenly notieed to bo unable to eat, 
Rni.1 bis Tiiang'er is foniid to cont:iin mitdi saliva mid frothy food that 
bus been ivtiirni^tl IbruuKh bis nose. Tbe $j/mptoms whivh enable u.s to 
tell that paralysisol' tbe pharynx exiuta are asfollovrs: The owner sa>'s 
hebusahonte that "can't cat.^ That Is all he knows. Wo Hud tbo 
animal witli a somewhat anxtons ecmntenance; manger, as above tie- 
Bcribed; ]tul»c, ix-s|)i ration, nud temperature, at 0rat, about tbe tuimo 
as in health; the horse will constantly tr>' to cat or drink, but is nn- 
ablolodosn; if tTat«r be offered him from 5 pail ho will npjHiiently drink 
with avidity, but, if wc notice, tbu qnantity of water in the [iHil remains 
abontthe same; ho will continue trying to drink by the honr; if ho can 
succeed ill getting any Quid in to tho back part of tbe moutU it comes 
ont at once through the noiy*. Fwjils also reliirii tlimngh the nose, or 
are dropiwd from the mouth, quiddc-d. An examination of tlie month 
by inserting the band fails to And any obstruction or any abnormal 
condition, except, prrba|>s, that tbe partji are too Oabby to tbe touch. 
These cases go on from ba^l to worse ; tbe borse constantly and rapidly 
losos in coudition, becomes very much vinaciatM, tho eyes are hollow 
and lustreless, and deatb soon occurs from inanition. 

Treatment is very unsatisraatory. Bevcro blisters sbould be applied 
behind and nnder the jaw; tbe niotitb is to be frequently swabbed out 
with alum or chlorate of [)ot:ish, 1 ounce to a pint of water, by means 
of a s|ions:c fastened to Ibn end of a stloli. Strychnia is tbo best agent 
to be usftd to overcome this paralysis, and should bo given in 1 ^'niin 
dottes tliree or four tiiuos a day. If the eerviooa of a veterinarian oan 



27 

be obtained h» should give this medicine by means of » bypodermie 
syringe, injeeting it deeply into the pharynx. In my experience the 
blister ext^nally, the iireqaeDt swabbing of the month, as above de- 
scribed, and the use of a nerve stimalant are all that can be done. This 
disease may be Diistakea at times for foreign bodies in the month or tcr 
the so called cerebra-spiual meningitis. It is to be dIstiDgnished from 
the f<Hiner by a carefinl examinatioQ of the month, the ^iseDce of any 
offendiog body, and by the flabby feel of the month ; from the latter by 
the animal i^peariDg in perfect health in ereiy particular except this 
inability to eat or drink. 

Abtamaea sometimes form in tbe pharynx and gire rise to sympttnns 
resembUng those of laryn^tis or distemper. Interference with breath- 
ing, that is of recent origin, and pcDgTession, withont any obso^'able 
swelling w soreness aboat tbe throat, will make as snspeet the forma- 
tion of an abscess in this locatioa. Bat little can be done in the way 
of treatment, save to bnrty tbe ripening of the abscess and its dis- 
charge, by steaming with bops, hay, or similar substances. If the ab- 
scess can be felt throogh the mooth it most be ojiened by the attend- 
ing veterinaiy surgeon. 

DtSKASES OP TnX CESOPHAGCS OB CriXET. 

It is raze to find disease of this organ, except as a result ot the ib' 
trodoctioa of foreign bodies too large to pass, or to tbe exhibition >jt 
irritatiDg medieiBea. Great care should be taken in theadministiatHm 
of irritant or caastie medieues that tbey be tbonmgfaly dilated. If 
this is not done erosioos and nleeratimis of tbe throat ensue, axtd this 
again is prone to be foUowed by constriction — itarr^wing — <>f the gullet, 
Ibe mechanical tnMble of choking is quite erjoimoii. It fre^jueutly 
occurs vben tbe animal is suddenly starttol wage eaung spptew or rtwts,

Supturt of tht itomach.—T\m mo«tIy occurs aa a result of engoi^d

opening of the stoiuoch into tbo iutcRtiucfi, and rorj violent pulling or 
jnmping imnieitiatcly after tbe aniuiiil ba^ eaten heartily of bulky food. 
These or similar causes may lead to this accident. ^

the horse has been fed at the lust meal. Vomiting has, pretty gen-

to prefaeo what I may ttuy conceming this with the statement tliat I 
have observed voniitiDg when tbe pottmortem e:iam{natlou revealed 
rapture; that I have found rupture of tbe stomach where vomiling 
bad not ocenrretl; that I have wilntuuted vomiting n'hen< the horse aooQ 
after made a rapid recovery* i. e.* when the stomach was not ruptured. 
Id spite of this ooatradictory evidence, I am of the opiuion that^ takea 
In eonneclion with other symptoms, this sign is of value ns pointing 
toward rupture of the stomach. This aecideut has occurred in my _ 
practice mostly in heavy draught borsea. A prominent symptom ob< ■ 
served (though 1 have also 8e«u it in diophragmatio hernia) is where 
the horse, if pas-sible, geU the f^nt feel on hight^r gnnind tbao the

relief to some extent, and it will be muintaine<l fur some minutes; ttie 
also quickly regained when tbe horse has eliangetl it for some otber. 
Colicky sym])CumH, of course, are present, and these will x'ary much, 
and present no diagnostic value. As the case progresses " tlie horse

ISDIGBSTION. 

Ittdfgeittion is a term applied to all those conditions vbcrc, from any

wltneKM in tbe borse ii.vntploiiis siniilur to those of dyspepsia in uiau. 
The diritnrbuneeji of digestion inoluded under tbi» biMtd are not so pro-

digestlTe orfjans nonld be incomplete if we failed to mention this, Ibe 
most fl:>e(iiieiiit of all digestJ%'e diAonlers. The seal and causes of iudi- 
j^estioii are found to vary in different bor^e,-^ or even iu tbe Kama bor«o 
at dift'erenl: times. Apart from the imtigcstlbility of the food itself 
there are many canses prodiiettvoof indigostioD. Tho teetb ara oricu 
at fault. Where the-'U! are sliarp, irregatar, or decayed thu fiKid is im- 
iwileclly maaticated and swHlloweil before there is a proper admixture 
with the saliva. Boiling of the food; the bile— secrctiou of the liver 
— may be defeclire in quality or quantity; there may ho lack of secre- 
tiuti of tbe iHiueroiitic juice, or there may bo mimply waul of peristaltic 
iDovenieiit of tbe sloinitcb and intestines, thereby causing an tutcrrup-

bowet'er, Is in tbe stomach or small intestinns. Whenever, from any

IKTBSflXAL WOKMS. 

Allboii[;lt there are several speetes of worms found in the intestines 
of boncest it will be suilicient, In an article liko this, to refer only to 
three or foor of the mo.'it common ones. Worms are most fruijuently 
seen in young liorAOS, ami in tho&e that are weak and debilitated. They 
(xnamonly exist iu homca that are on low^ wct^ or murshy pasturea, ttod 
la those tliat drink stagnaui- water. 




tptM 



T1j« iutestina] worm moat coiuuionly seen is known as tlic Lumbritoii 
worm. lu form it is tuucb like tho coiuiuouearib-vroroi. ItJswliitcoi 
red(li«li in color, nod tiicaiinrcs from 4 to 12 inclu's iu length, tbongh 
soiDo iiiive been Keen that w(>re Di-ar1y 30 iiicbes lung. Id tbickticss 
tlu'y vary from the size of a rye Btxuv to tbat b{ a la(l>^ little ADger, 
bein<; tbickeat at the midtHe, and tapering »t both eada. They are 
found stugly or in groiiim or masBC^, And infest uUietly tlic small iutoi 
tiiii?s. 

Atiotlier commoi) variety of intestinal worm is called tbe pfn-uwi 
ttiid is found mo);tlyintliu largo iiitcatinci). Tbc8«&ro8i:mi trauspaivii 
thrciul liko worms, nie^jsuring in length from 1 to 2 inches. 

Tliv tiiiJf-worm, onee Kiwn, is easily recoynizi'd. It is whllo, llatj' 
tbio, broad, and jointed. Tlio bend is found at the snmllrr end of Ibc 
vorni. Tupc-n-oriDS of tbc borso aomctimos meAsuro from 20 to30 feet 
in lengtli. 

Hi/mptoing o/ intestinal irormt. — Slight colicky pains are noticed at 
times, or there may only Iw switching of the tail, frequent paNsnges of 
muimre, ami eotne slight Htraioing, itching of the anus, and rubbing of 
the tnil or rump against tbe stall or fences ; tbe horse is in poor coudi 
tion ; does not shed his coat; is bide-boiiiid and pot bellied ; tbo up 
titv is depraved, licking the wallH, biting the wooilun work of tlie stall 
licking parts of his body, eating earth, and being i>articularly fund of 
sail; tbe bowola are irregular, uoustipatiuu or diarrhea beiug uotlced. 
Borne plnco mnch dependenco npon tbe symptom of itching of tbe up- 
per tip, OS shnvrn by the lioisc frcQnenlly turning it up and mbbing it 
upon tbe wall or stalls. Others again declare tliat whi-iiever we see the 
adherenco of a dried wbitisb stibstnuce about the anas worms arc pres- 
ent. The one symptom, however, that wu should always look for, and 
certainly tbe only one tbat may not deceive us, is seeing tbe borso pass 
Uie vorms iu his diiiig. 

Treatment. — Kemedies to destroy intestinal worms are much more t»f- 
flclout if given alter along fast, and then tbe worm medicine must be 
BUpptcmente<l by a physic to carry ont the worms. Among the best; 
Tormmcdtciucamay b« mentioned santouiuCf turjieDtiQc, tikrlarometio, 
iofasion of tobacco, and bitter tonics. To destroy tajie-wurms, ureon 
nut. male-fern, and pumpkin seeds are tbe best. If a horse is pass- 
ing the long rannd worms, for instance, tbe plan of treatment is to^ 
give tvice daily for three or foar days a drcncb composed of turpen-J 
tine, 1 onnee, and liuu'cd oil 'Jov^i ounces, to l>e followed on the Amrth^ 
day by a physic of Ttarbadoes aloes, I ounce. If tbe pinwoniis are 
present (the ones tbat infect the large bowrls), injections into the re 
tam of infasions of tobacco, infusions of qnassia cbi|)S, one half pouuttj 
to a gallon of water, once or twice daily for a few days, and followe<l bj 
a pfayNic, are nio.<'t heneticial. It sbnnid be borne in miiiil that intes 
iioal worms are mostly seen in horses that aro in poor condition; and 
ftD uficutiat part of oar treutuiout theu is to improve the appetite and

^paimodic or cramp cotic. — TbJa is tbe name given to that form of colic 
>i1a(«d by contmcttori, or spaam, of a (wrtion of tbe Binall iiitesliues. 
It is pPoduc!e<l by iudigestibic food} foreign bodies, as nails und stoDta

high-bred, ronnd-barreled ner^'oos horses than in coarse, lymphatic 
Dues. 

Sgmpto»t9.—Tbes& fihoald be carefully studied io order to diagnose 
this from otherformsof collerequirtngquitodiOereattroutQient. Spas> 
modiv colic nlwuj'K begins snddenly. If fei'diug, tbe borstt is seen to 
atop abi'iiptly, stamp impatit'Dtiy, and probably look baukw.ird.t. llv: 
soon evinces more acute pain, and this is shown by pacing, enddenly 
lying down, rolliug, aud gettiug up. Tliore isthcii an interval of eiisej 
be will resume feeding, and ap[)e)ir to be entirely well. Tn a little while, 
however, tbe ]>aii)H n;ttirn and an> luereaHed in severity, only to ngiitn 
pass off for a time. As the attack progresses these interrals of ease 
become shorter and shorter, and pain may be oontinuous, tboiigli oven 
now ibere an- *!i!ireib;ttinns of piiin. Animals Hiilft-riii;^ from this form 
of colic evince the most Int-emc paiu ; thoy ihrotc themselves down, roll 
over und over, jump up, whir! about, drop down again, paw, or strike, 
rather, with the front feer, steam aud sweat, make frequent attempts to 
pas!t tbcir urine, and the penix is partially erected. Only u small 
amount of water is passed ut a time» aud this is due to the bladder he- 
iog 80 nrcqacotly emptied, i, e,, there i9 but Utile tcatcr to jxug. Thcs« 
attempts to urinate are almost always regarded an svre symptoinnof 
tFuulile of the kidneys or bladder. In reality they are only one of the 
many wayrt in which the horse eipresses the pro&encti of paia. Allow 
IDC to digress slightly, and to assure tho reader that diiieases of the 
bladder ur kidneys of the horse are ejxteedintjlif rare. The stomach and 
botvels are aflected In a thousand instances where the kidneys or blad- 
der are oncft Attempts to i>as8 water and failure to do so are not 
erf>nch to warrant as in pronouncing tho case one of "trouble with Ida

loins, declunj that kidney disease exists. Try this pressure ou any

Tretttmeni.—S'mec the pain is dae to epaam or cramp of the bowela, 
iQedicines that overeoino spasmts — auti-spasmodics — nro the ones indi- 
cated. Prabably there is no meiliciiie Iwtter thau ubloRiI hydrat«, 
This i« to b« given iu a dose of 1 ounce in a half pint of water as a 
dreuub. A verycommou and good remedy is sulphuric ether and land- 
aniiui; of each ii ounceo in half pint of linseed oil. Another drcucb 
Day be comjiosed of 2 ouooes each of sulpburio other and alcohol In 8 
omiceK of water. If nothing else is at bnad we may give wbittky; ona- 
lialf pint iu bot water. If relief is not obtaint^d in one boar from any 
€f the above doaea, tbey may then be repeated. The body should be 
vnnnly clothed and perspiriition ii)duoe<l. Blankets dipped in very bot 
water ro whieh a small quantity of tuqieiitiiie ban been added should 
bo placed arouiul the belly and covered with dry blankets, or the abdo- 
men may ho rubbed with slimulating linimonta or mustard- water. Tbo 
difllenlty, however, of applying hot blankets and keeping them la place 
fureeK us, iu mo-it lustances to dispf^nse with tlieni. If the cramp is due 
to iiritanta in the bowels u cure is not compltte until we have giren a 
cathiu'tiu of 1 ounce of alues or 1 pint of linseed-oil. Iiijectious into tbO 
rectum of warm, soapy water, or salt and water, aid the cure. 

Oue wonl here about Itijuctions, or euemiii, as they are called. These, 
OS a rule, should be Inkewarm and from 3 to G guarta are to be given 
at a time. Tbey may be repeated every half hour if nccc^ary. Great 
care Is to be taikuu not to injure the rectum in giving rectal injections. 
A large syringe is tbo best means by which to give them. If this ta 
not to Ih! had, take a largo eldi^r, from which the pith baa been removed, 
or a piece of hose. A huge hog's bladder is to be fllWd witb the fluid 
to bo injeeled and tied about one end of the elder or hose. Tbo point 
to be hitro<luced into the rectum must be blunt, rounded, and smooth. 
It is to be tboroaghly oiled and then carefully poshed through the anus 
in a slightly upward direction. Pressure upon the bladder wdl force 
ita contents into the Imwel. iliicb force mvist be avoided, for the 
rectum may bo lacerated and seriouH oom plications or even death re- 
salt. Exercise will aid the action of the bowels in this and similar 
colicky troubles, but severe galloping or trotting ts to be ouudemued. 
If the horse eati b.iV4> a loose bos or juiddock it is the best, as bo wtU 
then take what exercise be wants. If the patient Imj Bztremely violeut 
it is otlen vrixfl to rvstrain him, since rupture of the stomach or dis- 
placemeucof the bowcU may result aud complicate the troublcA.

Iwptiction o/ the large i,'i?c«(i»M. — Tliis is a very (■ninmon Imwcl tronble 
and oim which, if not promptly recogiiixi.>iluud proj^erly trc>at«d, rvMilU 
iu death. It is caosed mostly by overfeeding, c8i>ecially of grain, and

with other grains; old, dry, hiird bay, or stalks nlieu largely fed ; doll-' 
cit!n4jy of secretions of tbe intestinal tract, lack of water, waut of exer- 
cise, paralysis of uervo endings, medicines, etc. 

S}imptom6. — ImpactioD of the larg« botrcls is to b« diagDosod by a 
slight nbdominiil pain, which may iti8api>enr for u day or two to reap- 
pear with more violciee. The feces is passed somewhat more frccjucutly, 
but in smaller qaautities aod more dry ; the ahiloniea is fall, but not 
distCDdcd with gas ; the horse at first is noticed to |>aw and soon begins 
to look back at his aides. Probably onu of the most characteristic 
symptoms is the position assumed when down. Ho lies flat od hiB 
side, head and legs pxlt-ndcd, occiisionally raiHint; his bead to look 
toward his dank j he remains on bis side for from five to tifteen tninutce 
ftt a time. Evidently this position in the one giving the most rrocdom 
from pain. TTorises at times, walks abont the stidi, paws, looks at bis 
sides, backs tip against the stall which he pn-sst-s with bis tail, and 
Boou lies down again, assuming his farored position. Tbe bowels bavo 
oease<l entirely to more. The pulse is bnt tittle ebangod at flrst, being 
fall aud sluggish ; later, if this condition is not orcrron>e, it l»L'Com<« 
rapid and feeble. I have known hor«e« to suD'er from impaction of tbe 
iKJwels for a week, yet ereiitnally recover, and others have reported 
cases osteuding two or even three vreeka which ended favorably. As 
a rule, how*'vor, they seldom last over fonr or flro days, many, iu fact, 
dying sooner than this. 

The treatmeut consists of efforts to prodaoe movement of tbe bowels, 
and topn'vent indammation of l he same from arising. A Inrge cathartic 
is to be given us early an passihlo; either of the following are reoom- 
meuded: Powdered Barbadoes aloes 1 ounce, calomel 3 ilrams, aud 
powdered unx vomica 1 dram; or liuseed oil 1 pint, and crotou oil 15 
drops. Some favor tlio administration of Epsom sails, 1 ponnil, with 
oue-4)narler iiound of (x>mmon salt, chiiming that this causes the horse 
to drink largely of water, and thus mechanically softening the impacted 
mass and favoring ita expulsion. Whichever physic is selected it ia

pcct the pre-.s«noe of atone ia the Htomach, if there ia a hiKlur}' of de-

those of obstruction, followed by those nf inflammation and gaiierene, 
and are not dia(;niMli>(\ Tlii'r« is, of cotiroe, no treatment that will 
prove effective. Wo can simply give remedies to move the bowels, t« 
celieve pain, and to combat inflammation. 

Inteitinal eoncretiong, calculi (atonet) in the iutestinea. — Thcsa ooncr^ 
tioDS are found mostly iu the large bowels, though they are occasiotially 
met with in the small intoetlne«. Ihey are of various sizes, weighing 
from 1 ounce to 25 ptmnds ; they may be single or multiple, aud differ 
in composition aud appearance, some being soft (composed mostly of 
animal or vej;rtablc matter), while others are iturous or bonay-oombed 
(consu<ting of animal and mineral matter], and others again that are . 
entirely bard and stone-like. The hair-balls, bo common to the stomach 
and intestinefl of (tattle, are very rare in the borw. Intirntinal calculi 
form around some foreign body oe a rule, mostly a nail, piece of wood, 
or somethiug of this description, whose shape they aasame to a certain 
extent. Layers are arranged concentrically aronnd snch nncleris until 
the sizes ab*)ve ajmkeu of ar« formed. Thcso atoue* are also often found 
In millers* horses, as well ftlaoas horses in limestone difltricta where the 
water is hard. Wlien the ualeali attain a safticient size and become 
lodged or blocked in Kome part of the iutCAtioea, they cnutie obslniclioD, 
inflammation of the bowels, colicky symptoms, and death. Some vete- 
riaRTians pretend to diaguoeo the presence of these bodies during life, 
but I know of no certain signs or symptoms that reveal them. Kecur- 
tian colics aud character of food and water may enable us to make a 
£01x1 gue--^ at times, but nothing more. 

Tbe ftfutptoms will bo those of obstruction of the bowels. Upon jk>#(-

TntuMstuception or Invagination is the slipping of a portion of the io- 
tCAtiDC into another portion imna«dtately H(UoiD)ng, like n partially

iDvagtnations occur shortly before death, and are dno to irrrgnlar con-

cular actions are, at tliia time, irregular and tumultnoas, and it is not 
snr]>risittg that intU88nM«ptlon is produced. *' I ntnsflusccptions of the 
dying'* are charact^rir^d by the fnllowing peculiarities: Thi'y art*, smnll, 
tree from any trace of congc-^tioii, iullammation, or adhesion, and cuu 
Tcry ta«ily be re<lucM by slight traction; they are apt to be mul- 
^ple, and aro most frcqnontly directed forward, fn obstruoti%'o intns-

Cntua of taraijimifi«n. — This necident is most likely to oooar in horses 
iliat are suffering from Kpaorn of the howid or in those wbern a ttmall 
portion of the gut is paralyzed, l^e natunil worm or ring-like con- 
traction of the got favors tbe passage of the contracted or paralyzed 
portion Into that in>rae<liately behind it. It may occur during tho ex- 
iBtunco of almost any abdominal trouble, as diarrhea, indammation of 
Ute bowels, or from injnr.cs, exifoeure to cohl, etc.

Voltutvt, Outtie or Ttcisting of tfu Boteels. — These aro the terms ap- 
plied to the bowels wben twisted or knotted. This accident is rathcra 
common one, and frequently rcsulta from the violent manner iu which 
a borse throws himself about when attiicked by 6](a.sp)odic colia The 
9ymp(onu arc the samn as those of iutussusccptioti and obstractions of 
the bowels; the same Uirectiuns as to treatment are therefore to ba 
observed. 

Diarrhea is duo to eating moldy or luuttty food, drinking stagnant 
water, di^ascd condition of tlio teetli, eating irritating eabstanccs, to 
being kept on low, marshy pastures, and exposure during cold uigbts, 
low, damp stables, or to some morbid or indaminatory condition of the 
intestinal canal or some of its annexed or^antt. It is more frequently 
a 8yui|)toai of functional disorder timn an organic disease. Somchorsoe 
are predispoKeil to scout and are called '^washy" by horsemen; they 
are those of long iMylies, toug legs, and narrow, flat side^ Horses of 
this build arc almost sure to ecoiirif fed or watered immediately befora 
being put to work. Fast or road work, of course, npffravates this 
trouble. Diarrhea may exist as a compliealiou of othiT diseasee, as 
pneumoaia and iufloeuza for instance, and agaia daring the diseases of 
tlie liver. 

The tymptoma are the frequent ev&ouattous of liquid stools, witb or 
vllhout pronounced abdominal pain, loss of apiielite, emaciation, ete. 

Treatment is at tixea very simple, bnt requires the utmost caro and 
judgment. If duo to faulty food or water it is sufBcicnt to change 
these. If it results from some irritant in tlte iotostjuea, this is best 
gotten rid of by the administration of an oleaginous purge, the iliurrhea 
mostly disappearing with the cessation of the operatlou of the inedicloe. 
If, however, purging continues, it may be cheeked liy giving wheat flour 
iu water, starch water, wbite-oak bark tea, chalk, opium, or half dram 
I o£ sulphuric acid la oaehalf pint of water twice or tbriue daily.

Suferjmrgation. — Thia is tbe designation of tiiat diarrhea or tluz 
from tlie bowels that, at timos, is iodaced by and follows tbe action of 
a physic It is aocomponied by mucli irritatitm or even iullamniation 
of tbe bowels, and is always of a serious character. Altboagh iu mre 
instances it follows from a usual dose of physic and where every jiro- 
cauLton bas been taken, it is most likely to result under tbe following 
circumstauoeH : Too large a dust; of phy:iie; to giving physics to horses 
enBTeriiig firom puetuuouia, infiucuza, or other dt^bilitatLngdideases; to 
ruling or driving a horse when parging ; to ex|)osare or draiight-s of 
cold air, or giving large quajitities of cold water while tbe physic is 
Oftereting. There is always danger of sniHTpnrg.ition if a physic is 
given toa horse suffering from diseases of thcrespiratory organs. Small 
and often -repeated pbysica are also to be avoided, us they produce de- 
bility and great deprension of tbe system and predisiiose to tbls dis- 
oMer. When a physic is to be given we idioold give tbo horse sloppj- 
fcod until tbe medicine begins to oiterate; we mast clothe tbe body 
■vith a warm blanket: keep out ofdranj^hts; givo only chilled water ia 
imall qiuDtitJes. Aftrra horse has purged fruin twelve to twenty-four 
lioare it can mostly be stopped or *' set," as borstmeu say, by ft^eding 
on dry oats and hay. Sboald the purging continue, howevtir, it is 
best trt^atcdby giving domulcoot drinks — tiiLoet'd tea, oatmeal or wbeat- 
flour gruel. After this tbe astrlHgeuls ivimki-ii of for diairfaca may bo 
given. Besides this tbe borse is to receive brandy in doses of from 2 
lo 4 ounces, with milk and eggs, foor or five times a diiy. 

Laaiiullis " foonder'* is a frt^^juent setjiiels; of KUperpurgation and is 
to Iw gaaided against by removing the shoes and statidiug the horse on 
moi&t sjiwdust or some similar bedding. 

i/ytcMUriy— WlUittuis defines UyseDtct^r, or bloody itux, as an iutee- 



tinal inflanimatory action of a peculiar or Rpecific cbnmct^r, attended 
witb fevm; occasiouat aMotntDal pain, aud lluid alviae dlscliargoa, 
mingled vitb blood or albnniinoiis materials ; tlio txtixim changes, vbiob

obarnct«rized by ctjffee-fiolored or bloody diitcliargtw, liquid, and very 
offensive iii odor, and passed with mach tenesmua (straiuiug). It IB 
very rare ia the horse. 

Cawfti. — Probably the moRt common canse is keeping yoniig tiorse* 
iu i»articular for a loug time ou low, wet, luandiy paetores, without 
other feed (a diai'rbea of long standing sometimes ternmiateM in dysen- 
tory) ; exjuitiurc during cold, wet weatlier; dccowiioscd foods; atagoaat 
vater that ooiitJtins large qnantiticsof deooraiKiRing vegetable matter; 
low, damp, aud daik stables, particularly If crowded ; the exiBtence of 
eotne disease, as t^iberculosis of tbe abdominal form. 

S!/mptom$. — Tbo initial symptom is a cliill, wliicb probably escapee 
notice in the majority of instancea. Tlie disoliarges are offensive and 
for the most part liquid, altbougli It is common to find lamps of solid 
fecal matter floating in tins liquid jKirtioii ; shredit of mucous membraao 
and blood aro passed, or tlic cvacuatious may bo muco-purulent ; tbora 
Js mtioh straining, and, rarely, Hymjitoms of abdomiuid pain ; the horse 
lies down a great deal; the pulse is quickened and the teinperatnre 
elcvatvd. Tbo appetite may remain fair, bnt in Mpite of thiei tbo boraa 
rapidly loaes Hesh and becomes a sorry-looking object Death rarely 
follows under two to three weeks. Tbirst is a prominent syniptom. 

7Vm(nt«nt. — This i.s most no satisfactory, and 1 am inclined to place 
more deiiendeuce upon tbo care and feed than any medication that may 
be adopted. First of all tbe borse must be placed in a dry, varm, yet 
well -ventilated stable ; the skin is to receive attention by frequent rnb- 
binga of the surface of the body, witb blankets, and bandages to tbe 
legs. The vater mast be pure and given In small quantities; tbo food, 
that which is light and easily digested. Medicinally, we mast give at 
first a light dose of castor oil, about onc-linlf pint^ to wbiob has been 
.added 2 oauoes of laadaunm. Tbe vegetable or mineral astrlugenta 
ari! also to 1h' {riven. Starcli injections containing laudanum often 
aflurd grcut relict Tbe strength must be kept up by milk puncbeo* 
eggs, beef tea, oat-meal gmel, etc. In spite of the beet caro aud treat- 
inent, however, dysentery mostly proves fatal. 

IlarmorrhoiJa — Ptleii. — These arc rare in horses, althuugb more fre- 
quently met with than most people suppose. They arc diagnosed by 
tbe appearance of brtghtred irregular tumors after defecation, which 
may remain risible at all times or be seen only when the borsu is down 
or after paHsiiig bis manun). They are mostly due to constipation, to 
irritation or injuries, or follow from the severe straining during dyaeo- 
tery. I have observed them to follow from severe labor pains in the

inragioatioQ, twisting of tbe bowels, eto. In fact, I can not remember 
ever to have Boeu hot ono cnso of enteritis apart from these or giiuilar 
canses. It in rlaimt'd, liowervr, by some that enteritis may be pro- 
dncrd by dritiktu^' -nhcu warm large quautiticM uf cold wat«r, driring 
through deop Htredms when the animal is heated, washing the entire 
surface of the iMxly at.sucb a tiuio, and by feeding moldy or musty 
foo«lB. or IcfWping the liorse in damp cellar stables. 

Symptoms. — Pobnlu Ayinptoms, from the omtct, mark all attacks of 
Idiopathic enteritis. Tbe membraoes of the nose, mouth, and eyee are 
congested and reddened, the month is hot and dry, rospiratinits are in- 
creased, the pulse is hanl and rapid, tem[H>rature is elerat4:d to 103'^ or 
105° Pab. UoUcky pains aro coutianous. Tbe horse walks abont the 
stallf paws, lies down carefulb', and mostfrc^iueotly turus biiuself upon 
bis back by the side of the tttiill and remaiuH iu this {losilion for Kume 
time. Thirst bt present. As a rale^ the bowels are sluggish or even 
<'ii;irL-.Iy inactive^ but when this disease is dae to irritant foodii or mod- 
it^uitft piirjiiuff aud tympanites may be prcseat- The inrtammatory 
pulse, high tem[ieratiire, continuous paiu, which is iuereased upon 
Itnssetirt', position of the horse when down, colduess of ears and legSf 
etc, will eunble us to dingnoRe a vamo of «mt«?rititt. Where enteritis fol- 
lows as a complication of diseases before descritxtl, the symptoms will 
dei>end u]>on the charHCter of the original intestinal disorder.* 

IVetUmeaf.— We must rely almost wholly upon opinm internally. 
Give I ur ^ drams nf powdered opium every three or four boura. 
One dram of extract of belladonna should be added to the above 
doses of opium. Onlomel in 1-dram doses twioo a day is also recom- 
mended. As a rale, purgatives and enemas are not to be given; our 
object is to beep tbe bowels as quiet an [msKiblo. IhiL hluukets applied 
to the belly, or counter- irritants to abdominal walls, ai-e ad vieable. Give 
BJucilagiDOOS drink.-*, as lin«eed tea, oatmeni gruel, and starch water. 
Avoid iili sulid foods that, are in the least hard, dry, aud indifjestible.

If, frtaen the eymptoinn of iuflauioiatioii snbside, the bowels do not act,

Treatment. — This is of bat little avail, siaoo the case has mostly uiude 
great progress before btniig seen. Probably the best douiCJttJc remedy 
is white-oak bark tea given iu large and frcqaeuUy repeated doses. 
Tauuio aoid, 1 draui, or tluid extract of ergot, 1 onnce, are preferable, 
if at baud, aud can bo given every half hour until four or Qvo doses 
have beeti taken. Hot appHcatiunx to the body— blankets wrung out 
of hot water and spriukled wilb turpciittuo — are to be applied fre- 
quently. Mnstard water should bo applied with smart friction to the 
legs. Coald we see these cases at their iueeption general blood-letting 
might [iroTe of Bcrvico. 

Hernia. — There are several different kinds of bemiac that require no- 
tice at this point, not all of which, however, produce any serious symp- 
toms or results. Abdominal beruia or raptures are divided into reduci* 
bU. irraiucibtef and strangulated, according to eondition ; and into mj/mi* 
nal, scrotal^ tmtral, umbilical and diaphragmatic, accoiding to tbcir 
Bltaation. A hernia is reducible when it cau bo easily returned iuto the 
abdomen. It cuusisUt of a ttuft swelling, without heat, pain, or any 
uueasiueas, generally larger after a full meal, aud <tecreases in size as 
the bowels Ijccomo empty. An irredttcibh hernia is one that can not be 
returned iuto the abdomen, aud yet docs not cause any pain or uneasi- 
neas. SirangHlated hernia is one where tlin content>< of the sao are 
greatly distended, or where Crom pressure u|>outheblood-vesseUof tlie 
imprtsnoed portion tbe venous circulation is checked orstopi>ed, thereby 
canaing extensive congestion, awi-lliag, inti animation, and, if not re-

and, with a hand in the rectum, endeavor to cat<!h bold of the wander*

Ventral krrnia, — In this form of hernia the ])rotni»ton in Ihroagh 
some accidental opening or raptnro of some of the abdominal coats or 
ooverlDgs. It may ue«ur at any part of the belly except at the umblli- 
ens, and is caused by kieks^ blo\rM, hf>Qks, serere jamping' or pnlliug, 
etc Ventral hernia in most (.iimnion la iiregnant mares, and is here 
dae to the weight of the fubtus or some degenerative changee taking 
placo in the abdominal coata. It ia recognized by the appearance of a 
■welling, at the Intsc of which can be felt the opening or rent in the 
abdomiual tunirx, and from the fact bhnt tie swelling containing the 
intestines can be made to disappear when the animal ia placed in a 
favorable position. 

Treatment. — In many instances there is no ocoasion for treatment, aud 
again, wheco the hernial soo ia extensive, trcutment is of no avail. If 
the hernia is small we may attempt a cure by the methods to be da- 
scribed iu treating of utnbilical henila. If we are furtiinnto enough to 
be present when the hf>n)ia occurs, and particniarly if it is not too large, 
we may, by the proper appUcatiou of a pad and broad bandage, effect 
a perfect cure. 

Umbitim! hernia is the passing of any portion of the bowel or omen- 
tum through the navel, forming a " tttmor^at tliis jwint. ThLs is often 
congenital in onr animals, and is due to the imperfoct closure of the 
anibilicas aod to the position of the l>o<^ly. Many cases of urabilic.%1 
hernia, like Inguinal and scrotal of the congenital kind, disappear 
entirely by the time the animal reaches Its second or third year. Ad. 
vancitig age favom cure in these fuise<8 from the fart that the omentum 
(swinging support of the bowels) is proportionally shorter in adults 
tbau in foals, iliua lifting the intestines out uf the hernial sue and 
allowiug the opening in the walls to close. Probably one of the most 
frequent causes of iimbilical hernia in foals is the practice of keeping 
tlicm too long from their dums. oausiug them to frrt and worry, and 
he hour. Tho contraction of the abtlomlnal muselee

lulls io the same luauneraa veutral lierois iei prodaocil, though this 
vcrj rare. 

Trtatment — Tho treatment of umbltictil hernia varies mach vith 
(liffVreut practitioners. We hIiouUI remcmlter Ihu fnct that coiigttnital 
herniae are often removed vith age, but probably congenital umfciffool 
heruiae less bwinoatly than otbcra. Among the many plans of treat*' 
mcnt am to ha uaentioned the application of a pail over the tumor, tho 
IHiil being held iu plaou by a broad, tight baiid»ge placed nrontid the 
animal's ttody. TUo chief objecliou to this is the difficulty iu keeping 
the pad in its place. BUstcN are ofleo applied over the swelling, and 
as tbe shin banlens and contracts by the fornintiou of scabs an 

rtficial baudago or presaore is prudui-ed tb»t :it limt-s is Kuctieasfb], 

Another tn^atrneiit that has gained considerable repute of late yean 
oonslftt« in first clipping off Che hair over tbe swelling. Nitric acid is 
then applied by a Rmali brush, nniiig only enough tn moisten the sktn. 
This Beta up a deep-seatod adbusivu iutlammatiuu, which, in very many 
oasea, closes the opening in the narel. 8till another plan la to h^eet » 

latioD of common salt by m^^ti» of the hypodermic s\Tinge at three 

' four points attout the base of the swclliug. This nets in the same 
manner as tbe preeetling, but in my exiierieuce is net as edectual. 

Others again, after keeping the animal fasting for n few hours, cast 
oml secure it upon its back; the bovrel in then carefully returned into 
the abdomen. . The skin over the opening is to bo pinche<l up and one 
or two skewers are to be ruu through the skin from side to side as close 
as poitdblQ to tho umbilical opening. These skewers are kept in place 
by poesiog a eord around the akin between them and the alMlomcn and 
■ecnraly tied. Oroat care must he taken not t» draw these curds too 
tij/ht, as this would cause a speedy slough of tho skin, the intestines 
WDohl extrude, aiid dtiath results If properly applied an adhesimt la 
established between the skin aud the umhiliiuis which eOectuallycloses 
the orifice. 

IHiipkragnalie hemia~ — This consists of the passage of any of the 
abdumiiial vitieeni through a riMit in the diapbraicin (midrifT) into tho 
cavity of the thorax. It is rather a rare acctdoot and onn often iuipos- 
Kible to diagnose during life. Colicky symptoms, accompanied by great 
ilifGcalty in breathing, and tbe peculiar position so often assumed 
(that, uf sitting uiMn tbe hanuche^) arc sumowbat charaeterlNtic of this 
trouble, though thnie tiyinptoms, as we hare alreaily seen, may be pree- 
ent during diseases of the stomach or anterior portion of the bowels. 
T.M-ii could wo pronount%, with oertaiaty, this form of hernia, there Is 
litili- or nothing that cau be done. Leading the horse up a very steep 
gangway or causiug hira to rear up mny possibly cause the beruial 
portloD 1o return to its natural ppsitiun- This is nut (juuugh, however i 
there.

ftomevrhatcommou froDi extcnstnoortbc ioHiiuiniatorir nction inrulviuf

lovg frequGutly from girangulnlcil bornia', iuvagioaUou, rnptnro of the 
stonincb, inteHtines, liver, or vroiiib. 

Ssmptomn. — Peritonitis i.s mostly precedt-d by a cbill ; tUe borse is not 
dis)>08e(l to move, and if compelled to do so, moveii wltb a stiO'or soro 
gait; be jtntrs witb tbe front foci, and probably suites at his belly 
witli the hind ones; lie* down very ciirefally, and as tbe t>aiti is in- 
creased wbito down, be tuaititains during moat of tbe time tbe standiog 
position ; be walks nueasily about tbe stalL CoDdtipaiioc i» usually 
present. Pressure on tbo belly causes acnte pain, ami tbe borwj will 
bite, strike, or kick at you if so di.sliubiHl; tbt' abdumeii is tucked up ; 
the extremities fine and cold. Tbo toraperatare is bigber thaa nonaal, 
rcacbiof from 103'^ to 101^ Fab. Tbo paUe ia pcrltouitia is almost, of 
itself, diagnostic; it is quickened, beating from seveuty to ninety beats 
per minule, aud is hard and iri'ry. Tbis peculiarity of tbe pubto ifl 
cbarncleristicof iuflaminatiou of tbe serous membrane, nod if oocorriog 
vitb colicky symptoms, and, in particular, if following auy iujaries, 
aecidcntnl or surgical, of tbe jierttoneuni, we may rest iisaured that 
peritonitis is present. Perltouitia iu tbe horse is moatl.i; fatal when ft 
is nt all extensive. If death does uob occur in a short time, the inflam- 
aaatioQ assumes a cbi-outc form, iu which there is au exteusivo effasioD 
of water iu tbe cavity of tbe Iwlly, coustitutiug what is ktion-u a8 
ascites, and which, as a rale, results in deatli. 

Tbe treatment of perilouitia is to hv Kouiewhitt like that of enteritis. 
Opium in powder, 1 to U drams, witb calomel, one b'alf dram, is to u« 
given every two, three, or four boors, and constitute oar main de- 
peudeuc* in this disease. Extensive counter-irritants over tbe belly, 
consiivtiucof mustard -plasters, turpentine stupes, or even mild blisters, 
arc highly recnnimeudeiL Purgatives mu^t never be given during tbid 
couiptaint. Should wo desire to move tbo bowels it csu l>o done by 
gentle enemas, though it is seldom ueccHriiiry to resort even to thin. 

Axcite»f or dropsy of tbe abdomen, is mostly seeu as a nvsult of sub- 
tcuie cr chronic peritonitis, bat may be due to diseases of the liver, 
kidneys, heart, or lungs. There will ho found, on opening tbe cavity 
of the Iwlly, a large collection of yellowish or reddish liquid; fi-om a 
few quarts to 8e%-eral gallons may Im* present, it may Iw clear in 
color, though generally it is yellowish or of a red tint, and coutttius 
Dumerons loose dalles of eoagulablo lyni[ih.

aela. 

Among tbe caatu that tejul to tliis disease \rc must mention first tbe 
ntiiuubitiat; oETiMst of overrucdiug, particularly duriut; bot weatber. 
Tbose horses that are well fed aod receive but little exei*cise — old favor- 
ites that are boiug liberally fad and bave passed the tium of servioe, 
pensioned hunies of yearn of faithful toil — these am the butt aubjecta 
for diseases of this organ. We must add to these cuasea tbe more 
mechanical ones, as injuries on the right side over tbe liver, worms in _ 
tbe Lirer, gall-stones id the biliary duct«, foreign boilies, as needier or I 
nulls ibat bave beeu swallowed and in their waiideriugs have entered 
tbe liver, and, lastly, in some instanoos, the extension of inllam (nation 
from oeigbboring parts, thus involving this organ. Acute hepatitis may 
terniinnto in chronic inllainniation, abscesses, rn[)tnru of tbe liver, or 
may disappear, leaving behind uo trace of disease whatever. 

Treatment. — This should oonsiat>, at first, of the attmiuistralion of 1 
ounce of Barbadocs aloes or other physic. A. large blister is to be ap- 
plied to the right side, letting it extend from a liLLle behind tbe gitth 
backward to the last rib and in width about 12 to^'^ iuche^ midway 
between the epiuo above and the middle of the belly below. Ueueral 
blood-letting, if bad recuarsu to early, most provu of much benefit ia 
acute iiillnmrautiOD of the liver. The vein in the neck — Jugular — moat 
be opened, and from 4 to 6 quarts of blood miiy bedrawn. Saline medi- 
oiues, to act on tbe kidneys, should follow this treatment ; L-ounoe do^ea 
of saltpeter or muriate of ammonia, repeated three or four times aday, 
are proluibly .is good as any. The horse is to bo fed sparingly on soft 
food, brau-iuasbea chiefly. If we prove suuceasful and recovery takes 
ploco, see to it that tbe horse nftcrwai'ds get<> regular exercise and that 
his food is not of a highly nutritious character, or excessive. 

It will, I thluk,be useless toattemptmuub of a description of chronic 
hepatitiiit the eymptoms of ibis trouble being so ob^touro that the veteri' 
nary snrgooo, in most cases, can scarcely bope to do more than diag- 
nose it by exclusion. True, ifa horse has had acute hepatitis and re- 
mains dull for too great a length of time, with oucasioual slight colicky _ 
ayinptoms, yellow membraneo, etc., we may not fear of being far wrong m 
in saying that this disease has pas;jcd to the chronic form ; but to diag- 
nose this form uf hepatitis, without any such previous kiiuwludge of 
the case, is, to tell the tratb, very often *' guess-work " with ua.

Ilia Is primarily a disease of tbe nerrons system or liver rather tlian 
tthe kidneys, yet, as tbe most prominentsyniptoni is the sweet urju«, 
■maybe treutt>«l itrrc. Its eatiMftnro varied, hnt rcsolvo themselves 
larp-ly into disorder of the Itx'er or di<<ordt!r of the braiu. One of the 
HQinent functions of tbe liver is the formation of glycogen, a 
le allied to grape-sngar, and pasrttng into it by fiirtbcr oxidation 
IB the blood. Tbis is aconst^iut function of tbe liver, but in beallb thu 
rrsnlUng sugar is bunie<l up in the circulation and does not ap]>ear in 
the orine. On the contrary, when the supply of oxygen is defective, aa 
iDoerlaiudiseasefi of the lungs, the whole of tbe sugar does not undergo 
«WDhnstion and tho excess Is excreted by tho kidneys. aI»o in certain 
Ihrms of enlarged liver the amoout of Kngarprodacel is more than can 
he disposed of in the natural way, and it apiwars iu tho urine. A tern- 



64 



porary swoetncsa of th« urine afteii iKSfiun after a hearty meal on 
staruhy food, but tills is due altogetber to the soperabniidaDt supply of 
the sngar-fonning fooil, lasts for n few hours only, unci hiiK uo iniIIio- 
logitiiit t^igiiillcdiice. In many cases of fatal glycosuria the liver i$ 
foniicl to he etilargtHl, or at least cougeiited, aud it tg fouiiU that the dii- 
onter cait be produced experlnicntally by agencies which protlace an 
increase*! circiiliitiou through the lirer. Thus Bernard prmluced gly^ 
caiuria by pricking the nbloDg iiicdullii at the base of the braiu closo 
to the roots of the paeuiiao gastric nerve, which faappeos to be also th& 
Derve center [vaso-uotor) which presides over the contractions of tfaa 
minute blood -vesiiieliii. The pricking and irrJlalion of thia center leads 
to congestion of tlu* liver and the ttxuesaivo production of sugar. Irri- 
tation carried to this point throngb the pneamogastrio nerve caase* 
sacchaFiue urine, ami, in keepin;; with this, dii^case of the jxincreas has 
been found in this maliuly, the irritation being conveyeU tht-nce to ths 
brain ttirougU the pneuuiogaatrio nerve and retlccted to the liver through 
tbe vasomotor nerve*. The same result follows the reflection of irrita- 
tion from other sonrces, as from dilFereni ganglia (corpora striata. optic 
thulauti,puiiK,(rerebelUin),(»4rt>brum) of the brain. Similariy it is induced 
by iDterruptiou of the nervous control along the vaflo motor traots, aa 
in dcKtrnctioii of the upper or lower cer^Hcal Kymputhetio ganglion, by 
putting the nervous branch connecting these two, in injury to the spinal 
marrow in tbe interval between the brain and the second or fourth dorsal 
vertebra, or in disease of the ocolinc plexus, which directly presides 
over the liver. Certain chemical poJsiMis al.'io c^iuso Navoharint; urino, 
notiibly woorara, strychnin, morphia, phosphoric acid, alcohol, «tber, 
chiorororm, quiniii, aDimouIa, and arRenic.

of a high di'Ufiity (1. 000 and upward). rapi«l los« of couditioii, scmfy, un- 
thrifty skin, eostiveness or irregnlarity of the bowels, indigestion, and 
the pnwence in the urine of a sweet principle, grape-sngaror inosite, or 
both. This may be mo»l. pmniptly detected by toncliing th» tip of the 
ton{;ne with a drop. Sugnr may l>e dett^cted simply by adding a tea- 
spoonful uf liquid yeast to 1 ounces of tlie oi-ine and keeping it liglitly 
stopped at a (v>mpi>ralure of 70o to 80o F., for twelve hours, when 
the sngar will be- found to havu been changed into alcohol and e;irboa 
dioxide. The Ioks of density will giveindicalion of the amount of sugar 
transformed; thus tt density of ].035in a iirino which waa formeriy 1.060 
would indicate iibuut 15 grainH of Ktigar t<i ihe llniil onncu^. 

InoKile or mnscle-sngar, frci^uently pres«ut iu the hursu's urine, and 
even replacing the glucose, is not fermentable. Its presence may ba 
indicated by its sweetness and llio ubsonci; of fcrini-ntatiou, or by tial- 
lois' te.st. Evapuratt> the susperLeil urine at a giMitttt heat almual U>

AOUTB IXPLi.MUA.riON UP TRR KIDHP.TS— 1O0T£ NKPHRITTS. 

Intlawniationsof tlie kidneys have been difterentiat«I widely, accord- ; 
ing at! they were acute or cbrouic, parcncbymutoas or tubal, sapparatiT* 
or not, with iiicreiwHl nr shrunken kidney, eta, but in a work like ibe 
present, utility will be consulted by claaaing all under acute or ekronie 
ir^flammation. 

The oauAMof intlamtnntionof the kidneys arc extremely raiicd. Coo- 
g««iioD ouuurM from the altered and irritant ptodueca paased tbrougb 
these organs during recovery fhim inHamniation8 of other organs and 
during fcvurM. ThiH may \aal only during the uxiKtcnuv of ita canties ■^ 
may persist and biKiome aggravated. Heart diseaws throwing the blood 
pressure back ou the veins and kidneys, is another cause. Diseaae at 
the ureter or bladdfr, ]>r»venting the escape of urinu from the kidney 
and causing iucreased fullncits and tension in its pelvis ami tubes, will 
deterniiDC inilammation. Decomposition of the detained unn« Id sach 
caites, and the pmdaction of nmmotna and otiier irritaitls, must also ho 
named. The advuncv of bouteria upward from the bliidder Lu tho kid- 
ney is another cause. The couaumptioii in hay or other fodder of acrid 
or irritant ]tlants, includiitg fiiugi, the absorption of uantharidine from 
a surface blisterud by HpuniMh Hies, the reckless ailmiaistratioii of din- 
relics, tho preseuce of stones in the kiduey, exposure of the surfaou to 
cold aud wet, aud the intlictiun of blows or spniins ou the loins, may 
contribute to its prwluction. Liver disonlcra which throw on tho Kid- 
neys the work of excreting Irritant products, diseuse& uf the lungs aud 
heart from which clots are curried, to he arrested in the small bloods 
TC£selH of tho kidney, and injuries and paralysis of tho spiual cord, i 
additional causes.

described under tbo lust beading, and may occur in the aume way from 
ovenlieten!»i')n in tctiinus, acute rheumatism, paraplegia, and bcini- 
plegisi,in which the niiiinid csu not stretch himself to stale, and in cys- 
titis, nfl'ectiug tbe body of the tjla<lder tmt not tbe neck. In all tbeae 
ca»e» the urine is suppressed. It also occurs as a re<sult of ditteaae of 
the posterior end of tbe spinal mnrruw and with broken back, and ia 
then associated with pjilsy of the tnil, and it may be of the hind limbs. 

The sffuiptomt are a constant dribbling uf urine when the neck is in-

application of Spanish flies or turgieotine over a too-cxteni'ivo aurfacc^,, 
euddcQ uxpoKnre of a perspiriag and tired horse to cold or wet, and tbe ' 
preseuce of acrid plants fu tbe fodder may cause cystitis, as tbey may 
nephritis. Finally, inllummation may extend from a disetuKd vugtn»

Tbe tymptoma are slight or severe colicky pains ; tbe animal moves 
bhi hind feet uneauly nr even kicks at tbe abdomen, IooWk aroand at

through a clean citbeier, and the btaddi*r thoronghly waobad ont vith 
a Holution of 1 dram of l>orax iu a quart of water. This must be ro> 
peated twice daily until the urine iio longer decomposes, becaust^ aa

Id the same way tho extreme liardtieKs of the water iu M-rhun dis- 
tricts mast be looked iipou as coiitrlbutiDg to the coQoentratiou gf tli4 
urlu« au(l vorreitpondltigly to the [irodtictioii of stODo. The carbonillfCi 
sulphates, etc., of lime and mngneaia taken in the wnter miiKt Iw hgain 
thrown out, and just in iiroportioD ai these add to tho ttolidti of Ue 
urine they dispose it to precipitate its least soluble coDStiiuents. That 
the horse is reiy obmxiouH to oalcnli on oertniii llmeetODe soils, aa otm 
the calcareous forioatioiis of central and wentern New York, Penmjl* 
Tania, and Ohio, in America.; of Norfolk, Suffolk, Derhysliire, Sbrop' 
ehire, and Gloucestershire, in England ; of Poitou aod Landes, in 
Frauco; nud Muolcb, iu Bavaria. 

But the siitiiration of the uriiio from any or all of these fsonditiosi 
can Duly be looked on uti an auxiliary cause, and uot aa iu itself u 
eOBcleat oue, except oq the rareac occasions. For a more dlnel 
and immediate cause we must look to the urRanio matter wliicli 
forma a targe proportion of all urinary calculi. This oonsititK of inacott, 
albameu, pus, hyaliue cAnta of tho uriuiferous tubes, epithelial cells, 
blood* etc., mainly ag:eitts that belouK to the doss of colloid or uod- 
crystalliue bodies. A horse may live for uioiiths and years with tho 
urine habitually of a high density, and having the mineral constitaent} 
in exccMH, without the lormatiou of stone or eravet; and again one with 
dilute Qrine of low specific gravity will have a calculus. 

Eaiuoy, Ord, and others furnish tho explanation. Tbey not only 
show that a colloid body, like mucui^, albumen^ pus, or blood, det«i- 
Diined the precipitation of the crystalUno salts in the solntiou, but tliey 
determined the precipitation in the form of globules or spht-rcs, cap** 
blc of developing by further deposits into caleuli. Heat intODSiflM 
this action of the colloids, and a colloid iu a state of dooom position is 
8I)ecially active. Tlio pn'R«nce,_lIifn!fori>, of developing fungi and 
bacteria must be looked upon as active factors iu causing calculL 

In looking, therefore, for the immediate causes of calculi we moat 
coosiderespeciiilly alt those conditions which determine the preaenoe 
of albumen, blood, and excess of mucus, pus, etc, iu tho urine. TbuA 
diHOa(ie« of distant organs leading to albumiuuna, diseases of the kid- 
neys and urinary passages causing the escapo of blood or the formation 
of uiueuB or pus, become direct causes of calculi. Foreign botlies of olt 
kinds in the bla«l<ler or kidney have long tieen known as dctermiuJn^ 
causes of calculi, and us forming the oeutml nucleus. This is now ex~ 
plained by the fact that these bodies are liable to carry bacteria intv 
the passages and thus dotormino deoomposition, and they ore furtht^r 
liable to irritate the mucous membrans aud bectime enveloped in a coat- 
ing of niucuN, pus, and jierhaps blood. 

The fact thai horses appear to suffer from calculi, cipeclally on the 
maguesiau limostouos, tlie some districts iu which they suffer from

and let tbe food l>e only sucb as t^ontaina a large proportion of titjuid, 
l^nols, mashes, turnips, beets, apples, pntnpkhis, ensilage, succalent

calculus is manifested only by the frequent passage of urine with gritty 
particles, by stlfTuess ot tbe loins aud bind limbs and by tenderness to 
preasare-, the most promising resort is a long run at pasture where the 
graMHes are fresh and succulent. The longcontiiiued secretioo of a 
watery urine will soiuetimi-s ruu.<(e the breaking down uf a cak-ulua, as 
tbe Imbibition of the less dense tluid by the orgunio spongebke frame

then it in not grasped by the contracting walln of the bladder, but way

If the Htone is too large to be estracte*! through the ur^'lhra it may 
be broken dowo with tbe lithotrite and extracted piecemeal with the

I'rtVtral cateuliut.— Stone in the urethra. — This ia less frequent tban 
in cattle and Hbcep, owing tu the larger size of the urethra iu tbe borse 
anil tlie absence of the Sehaped curve and Terinifonn a]>[>eDdix. The 
calculi arrested in the nrethra are never formed there, bnt consist of 
oystiQ calculi which have been small enough to pass through tbe ut-ck 
of the bladdiT, but too large to pass through thu wlioly bMigtU of tbe 
nrrtbra and escape. Snob calculi therefore are primarily formed either 
lu tbe bladdrr or kidney, and have the cbcniical coniii4].->ition of tbe 
otber calculi found iu those or^^niis. They may be urrctstcd at auy point ' 
of tbe urethra, from the necli of the bladder bacli to tbe bend of the 
tntte beneath tbu anus, and from that point down to the extremity of 
tbe jteuis. I have found them most fteqaenlly in the papilla on tbe 
cxtrt-uji' eud of the i>eni8, and imnailiati^ly behind this. 

The tifmptoma are violent straining to urinate, but wllbout auy dis* 
charge, or with tbe eitcnpo of water in drojis only. Exawiuatiou of tbe 
end of the pvuift will detect the hwelling of the papilla or tbe urethra 
behind it, and tbe presence uf a hard mass iu tbe center. A probo in- 
serted into tbe urethra will strike against tbe gritty calculus. If the 
atone has Ix'en arrested higher up its {tosition may l>u detected as a 
imnll, bard, Sensitive knot on the line of tlie uietbra, iu the median line 
of the loTTcr surface of tbe penis, ur on the floor of the pelvis iu the 
nie^lian line fW)m tbe ucck of th« liladder baelt to the bend of tbe urethra 
beneath tbe anus. In any eaw the urethra between (be neck of the 
bladder and the point of obstruction is likely to be filled with Duid, uud 
to foel like a dittt^ndcd tube lluctuating on prcj?8ure. 

Treatment uyiy be begun by on attempt to estrnct tbo calculi by 
manipulation of the p:ipilla ou tbe end of the [leniK. This failing, the 
calculus may be seized with a pair of fine-pointed forcejis and with- 
drawn from the urethra; or. if necessary, a prob&poiuted knife may 
be Inserted and the urethra slightly dilated, or even laid opeu, and tbe 
Btone removed. If the stone has been arrested higher up it muett be 
extracted by a direct incision througb the walla of tbe urethra and

WOUNDS ABOUT THE NOSTBII.8. 

Woonds iu tbia neighborhood are common, and are generally caused 
by |^>ltiug snagged on a uail or spliuler, or by the bito of another 
borse; or by getting *'ruu into,'' or b.v running againat somethiug. 
Occasionally tbe nostril is no badly torn and liLcerntcul tbat it is itn- 
poaalble to eHeet a cure without leaving tbo auimal blemishtil for 
IU&, bat iu the minority of instances the blemish or scar is due to tbd 
want of conacrvative treatment on tbe )>art of the owner or attendant. 
As soon as ]Ktaaible after Uie aceident the parts tihonld he brought 
together and held there by stitches. If too much time is allowed to 
elii|>se tbo sweliiDg of tbe parts wilt considerably interfere. The akin 
Id this neighborhrxid is thin and delicate, and therefore it is eaxy to iu- 
•ert sntares. Kever cut away any skiu that may be loose and hang- 
ing, or else a sear will certainly remain. Bring tbe parts in direct ap- 
position and place (he stitcbcs from a quarter to a half inch n|>ait, as 
circumstaueea may demand. It is not necesMiry to have &[ieeial snr- 
gcon»'' silk and needles for Ibis operation; good linen thread or ordi- 
nary Rilk thread will answer. The wound afterwards ont^y refjuirvs to 
be kept clean. For this purpose it should be cleansed and discbarges 
■wa«he<l away daily with a Bolutlan made of carbolic aeid I part, in 
i>ali-r40 parts. If the horse is inclined to rub the wound ngiiinst some 
olg^t **" account of the Irritability, his head should be tied by means 
of two baiter ropes to prevent hliu rubbing the wound o)K;n. The 
liesd should be so tied about too days, except when at work or eating.

bad treatment may canse it to ran into a dangerons eompIic:ition, It 
nbnold receive pn»|i«r attention. Tbe anlnial shouiit not lie wurke<l for

Tbe IwuflH di*rive(l from tbe liibalatiou of sleam can not beovei-eKll-

noses ibe Bteam to arise in greater abundance. By do means adopt 
the itemidonn metboil of sleamiug — advised by some authors and prac< 
tiee<l by many ptuplu — by pntting' tho head in » bag with but water or 
tealded bntn. CotninouHeuaewould be Huffieienttocotidemn tbe method, 
if those who practice it wonid only tbiuk. With tbe bead ao eloaely

btinv, and miicb vrornQ when tbe aniiual is ill, for then it baa a greater 
aeceiwity for pure uir. 

The borae ahould be made to inbalH HJeam four or Ave times a clay, 
about flfteea or twenty uiumtcis eiieh time.

If tbe aDioial is constipate«l, relieve this symptom by injections 
(eaenaa) of u-arm water into the rectum (laat gut) three or lour times a 
day, bnl onder no clrcumstaneea administer pnrgative medieiaea. 

For simple ca>te«i tbe foregoing in all tbat is reqnireil, but if tbe ap- 
petite is lost, and tbe Animal appears debilitated and dtill, give 3

CHBOmO OATARIte— NASAL OLEET. 



d 



Tills is a snbacut© or chrontc inflanmiarUm of some part of the mem 
braiiu atlVotvd iu comiiiun cold, the disease just described. It is uiani- 
festcd by a persistent discbarge of a thick, white, or yellowish- vbite 
matter lYoru odh or both uoslriis. Tim Bbnisesof the head are the nsaal 
seat of tho diseiise. The commoDesI cause is a neglectetl or badly 
treated oold, and it uHuatly follows those cnses wbi^re the horse bag 
Bnffered exposure, been overworked, or has not received proper food, 
and, as a consequence, bas become debililaled. 

Other but less frwiuent causes for this afTeoIion are: Practnres of 
the bones that iuvolv« the membrane of the minuses; aud even blows 
on the bead over the sinuses, of suQicient force to rupture blood-vessels 
witbin. The blood thus escaping into the sinus acts as an irritant, and 
sets up an iiilluinnialion. DJNensed teeth often involve a sinus, and 
canso a fetid discharge from the nostril. Violent eougblug is siild to 
have forced particles of food into the sinus, which acted as a cause of 
the disease. Tumors growing in the sinnsies are known to have eaased 
It. It la also attributed to matter from disease of the tnrbinateil bones. 
Absorption of the bones fonuirjg thn walla of the Kinusos bas been 
oaased by thn pressure of pus collecting in them, and by tnuioro tilling 
up th« cavity. 

Symplomi. — The long-ctnitinucd discbarge, which vnrie-s in quantity 
according to the attendant circumstances — the cause of the trouble aud 
tbe part afTcctvd — will invariably indicate the diseiisc. Great cantioa 
must be exercised when examining thcKO cases, as horses have beea 
ooudemued as glaudcred wheu really thure was nothing more aiUug

discharge is frou one nostril only, which sigiiiJloit that the siuusea on 

that side of the ben<l are affected. The discharge may be ititerniittentt 

that is, qnantities may b« <lischar£;od at times, and ngnjii little or doqa 

for a day or so. The {^Intuls inidi^r and between lh« bones of the lower

The eye on tbe side of tbu discharging nostril may have a jteculiar 
Opt'carauou and look smaller than its fellow. There may bo an eularge- 
BKnt, having tbe appeanince of a bulging out of the bone over the 
imtt affcetiHl, l>etweeJi or bi-biw tbe eyes. The breath may be ofleimive, 
vbicJi fuOicatas decomposition of tbo matter or boneS) or, especially, 
disMw of tbe teeth. A di8ea#i-d tooth is further indicated by tbe 
kana holding bis bead to one side when eating, or dropping the food 
boiu the mouth after partly cbewiug it. When you lap on the bonea 
belveen the eyes, below tbe eyes and above the back teeth of the 
ii|<p«rjav, a hollow drum like sound is omitted, but if tbo siuus is 
Ulfd tfitb pus or eitntaiiis a large tnnior the sound eaiittetl vill l>o tbe 
wdo as if a solid ttiibstauce were struck; by this means the siuua 
tfltttM] may be locjited in some JDotances. Tbe hair may lie rough

fooil and regular exeniise. Tbe fund, or box containing it, sboald be 
filBccd on the ground, us tbe de{>cudvut position of tbe head favors tbe 
(lUcbarge. 

The cases that do Dot require a surgical operation must, as a niJe,

As already stated, tbo pharynx Is cotnmoD to the fnnctions of bolli

larynx and theiioc onward to tbe lutigs. Iu the |K>stcrior jtart of ilis

which the food and water pnss to the stomach. lutlauimation of the 
])barytix is n comjdSeation of other diseases, tiz., inlluetixa, atranglM, 
etc., Mud IS probably always, more or lesa, complicated with inflamma- 
tion of the larynx. Tliat it Hiay<>xi«taa an independent Rfft-etion there 
Is no rcasou to doubt, but so closely do the symptoms resemble those 
of laryngitis, and its tbe treatment is tbe same as for tbe latter disease, 
it is unnecessary to give it further cousideratJon in a separate article. 

SOBS TaKOA.T — LARYNOITIS. 

The larynx Is situated iu the epace between tbe lowerjaw bones just 
buck uf tbe root of tbe tongue, aud is retained iu this positH>u by the 
wiudpipc, muscles, and boiie^ to which it is attached. It may be c«a- 
sidered as a box (somewhat depressed on each side], compused priuci- 
l»ally of cartilages aud Btaall muscles, and lined on the inside with a 
continuation of the respiratory mucous menibrano. i'oelrnorly it o]>eua 
iuto and is continuous with the windpipe. It is the organ of the niiue, 
the vocal cords beiug situated witbiu it; but lu the hor»e this funcUoo 
ia of tittle or no coosequencc. It dilates and contracts to a certain ex> 
tvut like the nostrils, thus nr^ulatiug tht^ vulumeof air passing through 
it. Tbo mucous membrane llulug it Interually is so highly sensitive 
that if tbe smallest particle of food hupi>eus to drop into it from lite 
pharynx the mnscle-s iiistiiutly luntracb aud violent oougbiug ensues, 
which is ountinuc-d until the sourcv of irritation is ejeotetl. This is a 
Vise prorlsioh of nature to prevent foreign sub.'ttauces gaining aoceas

and in some cases the food, i» n^turiied through the nose. The mouth 
Is hot, and saliva dribbles from it. The glauds betni-cu the lower jaw 
boues and belov the ears may be swollen. Pressure ou the larynx 
tlidac4>8 a violent fit of coughing. The oough is very eharacteristtci It 
iseasiljr seen tiiat the animal is "coughing at his thniat." The head 
Ib nnre or less "poked tmt," and has thn appearance of Viug »lifily 
carried. The membrane in the noae becomes rei>l. A ilischarge from 
the nostHls soon appears. As the disease ndvaiiccs, the breathing may 
asMiHK^a more or less nuisy eharacter; sometimes a harsh niKping ttuore 
is emitted with every respiration, the breathing becomes hurried, and 
fKcasioDally the animal seems threatened with suffocation. 

Tr^dHf'Hf. — In all cases steam tliK UfwtrilK a» ndvitwd fur euld in the

hoars, ontil relief is alTorded. Have a fresh bucketful of bolliog water 
evrry flftren or tweuty minutet*. In each huckt^tfid of water put a table-

him all tbe time; he will not driuk too much, nor will the cold water 
hurt him. Constipation (if present) must be relieved by enemas of 
warm vater, admiuistered three or four times during the twenty-fonr 
hours.

some part of tbe respiratory tract. Knsal polypi, thickening of the 
meoibraoo, pharyngeal polypi, deformed bone^, paralysis of the wtuj? 
of the uiistril, etc., are ocwiaional causes. The noisy breatbiiijiof lioraes 
After having been idle and put to Hnddeii exertion is not «lne to any dis- 
eaw, aadtsoaly teiajwrury. Very ofleua aervouH,excitablB horse will 
make a nnioo fnr a short time when startetl off, generally cansed by the 
craaipL-d puaitiou iu which tbu head and neck are fureud, in order to liiild 
him back. 

* Many other causes may occasIoo temporary, intermittanf; or penua- 
t nolMy respiriitiuii, but after all other ^an^eIl itreetiunieruted it will 
be fonnd that more than nine ont of ten cases of clironiu roaring are 
eaa»ied by piirulysis uf the mnsclea of tliu larynx j and ulmo«t invariably 
Ic i^ the mnsclea of the left side of the larynx that nre affected. 

In chroiiie rouHui; thu noisti itt niHdc whfin the air is drawn into the 
lougif; aud oidy when the disease is fur odvunccil id a Round jirodm^ 
wbvn tbe air is expelled, aud even then it Is not near so load as during 
inspiration. 

Lu a normal condilioD the moxclca dilate the a]H'rtur« of the larynx 
by moving outward the cartilage aud vocal cord, allowing a sufllcient 
Tolamo of air to rash through, iiut when tlie u)uiM:les are paralyzed, 
the eartUage aud vocal coni that are normally controlled by the af- 
fected muscles remain stationary j therefore when tbe air rushes iu it 
lairttH this obstructioui and the noise is producetl. When the air is or- 
felled from the lanffg its very force pushes the cartilage and vocal oordB 
out, and consequently noise is not always produced tu the expiratory 
act.

Tlie paralysid of tlift masclca is dop to ilcrnn^tncnfcortlionenrn tbf>t 
«up)>lt«H tliem uritU eiinrj^^y. Tbo muftcluK tif l^th Bitlest are not Hupiiiit^] 
by ibe same nerve; lliere is b right and a left nerve, each supplying its 
respective 'si lie. The r<'a-soii why llm iniiKcles on tho left airte are Ibit 
onra aaiially pnnUysed is owing to tb» (lifTT-i-ciiuo in the unntoinical 
arraDgemeat of the nervea. Tlie left ocrve Is mnch ]r>nger aud more 
•xposBd to iotorferenoo than the right nerve. This pair of nerves is 
given off frcun its parent lrmiV« (the piii-iimo^ii^ttrics) ntttr th« latter 
enter tiic chest, antl consequeiiUj they are called the rccurreuL laryngwd 
RerveAi on account of baling to recur to the larynx. 

In clironio rmirinp there is no evidenee of nny disease of the laryni, 
other limn the wastt'd w)nditioii of tbt« mtiseles In fpiestton. Tho dis- 
ease of the nerve is generally located far from the larynx. Disease of 
parts contiguons to tlio Dorve nlong any part of its conrse may interfere 
wilh itK iiroper funetion It is not reiilly necessary for tbe nerve itswlf 
to be the seat of disease ; pressure U])od it is sufficient ; tJie pressure of

vithin the ebest through which the nerve passes ou its way back to the 
larynx is the most freipient inlernipliori of nervous supply, and conse- 
quently roaring. When roaring becomes confirnied medical treatment 
fa entirely uhoIcm, as it is imixiKAiblu to restore the wsated muMie aud 
at the same time remote the cause of the interrnptinn of the nervous 
supply. Before the disease beconieH i>t'r[uaiiout it may be l>etielicetl by 
a course of iodide of potasHium, when it is caused by disease of the 
lymphatic glauds. Hleotricity has betiO oscil with indifferent succi^^a. 
BliBtm-ing or flriug over the larj'nx is of course not worthy of trial if 
the disease is due to intwrference with tlie nerve supply. Theadniiois- 
tratiou of strychnia (nux voiuicat on the ground thai it la a nerve tonic, 
with tho view of stimulating the aflocteil moBOles, is treating only tbe 
result of the discam^ without considering the caiii^e, and if* therefore use- 
leas. The operation of extirpating the collapHed cartilage and vu(«l oord 
is believed to be the only relief, and as this operation iscrtiicaJaodcaa 
only bo performed by the skitlfal vetoriuarian, it will not be described 
- here. 

From the foregoing description of the disease it will be se«u that the 
name "roarinj;," by which the disease is gi'nerally known, is only a 
symptom uml not the disease. Cbrooio roariug is also in many cons 
Bceompanied by a cough. The best way to test whether a honte is a 
*' roarer" is to either make him pull a load rapidly up a hill or over a 
sandy mad or soft ground; or tP he is a eaddle biirso gallop him up a 
hill. Tbo object is to make him exert himself. Some horses require a 
great deal more exertiou thau otber^i before the cbameterisEic sound Is 
emitted. The greater thedistaunc he is forced the more he wilt appear 
eibansted if he is a roarer; in biid cases the animal h4L-cumt!M uttt^rly 
exbauKt«d, tho breathing is rapid aud difficult, the aostriU dilate to tbe 
fullest extent, aud tbe auimal appears as if suifocuUou was imminent.

ia situated on tJie superior surface of the rings. Internally tbotutw 
is lined with a continuation of tbe niucous membrane that lioea tbe

tion Is merely called to these defects, as they require no iinrticular 
attention in tho way of treatment. However, it muy bo stated that 
any one of tbe liefore-mentiuued conditions may constitute one of the 
causes of noisy respiration described as " roariDg." 

GUTTUEAL POUCaCS. 

These t^ro sacbs are not iooluded in tbe organs of respiration, bob 
eometimes pus collects in thcui to an extent that considerably inter- 
feres with respiration. They are in close proximity to the pharynx and 
laryux, and when filled with matter the fuiictioua of the last-named or 
gans can not be properly performed. They are Kiluuted above the 
throat, and commnnicate with tbe pharynx, an well as with the cavity 
of the tympanum of the ear. They are peculiar to KoUpcds. They 
contain air, except when filled with jtus. Their function is anknowo. 

Unu or both guttural pouches may contain pus. The symptoms are: 
Swelling on the side below the ear and an intermittent discharge of 
matter fruai one or both uostrilB, e8|M*eiaIly when the head ia depnsased. 

Tbe swelling is soft, and, if pressed upon, matter will i-w:ape from 
tho nose if the head is deprc<«e<l. As before moutioued, these poaches 
oommunicate with the pharynx, and tbrongh this small opening matter 
may escape. A recovery is probable if tho animal is turned out to 
graze, or if he \n (M from tbe ground, as the de|H>-udent position of the

Treatmeat. — Generally the horse is kept at work when be is aOected 
with this form of bronchial trnnble, as the owner says " he has only a 
deep cold. " It is true that soiau authorities vxprtrtttt rh*- opinion that 
work does uo harm, but they are mistaken. Kest is necessary, if a euro 
is desired, as even under the most favorable circumstiuiees, a care is 
difllcult to effect. The animal can not stand eiertion, and slioold not 
be compelled to undergo it, Ucsldes, there is n ^reat probability of 
acute bronchitis supervening at any time. 

The animal should have much the same general care nnil medical 
treatment prescribed for the acute form ; If material benefit has out 
been derived give the following: Powdered nux voinicii, 3 ounces; 
powdered ni-seuto, 70 f^ralus; powdered sulphate of copper, 3 ounces; 
mix logetberanildivideinto thirty-four powders. Ulvea powder mlxetl 
with bran and oats every night and morning. An application of 
muKtard ajiplicd to thebreast is abeneflcial adjunct. If all other treat- 
ment fails, try the following combination, recommended hy a roqA au- 
thority: Hydrocyanic acid (Schecle's etrcngtli), 20 minims; nitrate of 
potas.<(inm,3 drams; bicarbonate of soda, 1 oance; water,lpint. Tbla 
dose should be given every morning and evening for one or two weeks, 
If necesBiiry. 

The diet should be the most uonrlshlug. Bad food Is hanufnl at 
Btiy time, but especially in this disease. Avoid bulky fixxl. Linseed 
maaUes, scalded oata, grass ami grc>en-bIndo fodder, if iu season, is tJie 
best diet.

The lungs are the esseotial organs of respiration. They oqnstat of 
two (right and left) spongy masses, ooiiimonly called the "lights," 
sitaated entirely within the thoracic cavity. On account of the space 
taken up by the heart, the lelt lung is the smaller. I'^xtenmlly, they 
are completely covered by the pleura. The structure of the lung con- 
siste of a ligbt^ soft, but very strong and remarkably elastic tlasne, 
which can only Iw torn with diflicuUy. The lung of the fcptna 
which has never respired will sink if placed iu water, but after the

Iniif; has been infliited with air it will float on vater so long as Tipnltli;. 
Thi.H fact is miule astlul fu deciding whetheror not an auiinni njislwm

ber of lobee, whtcli oroftulMlifidvd into oiiioberless lobules (little Iobe«). 
A little bntucbial tabe termiDates in ever^ ouu of tlirso Hniiitl lolmlfs.

of ati inch; tbej liare bat one opening, lh» coiumuiiiciition with the 
branches of tb« little broncliial tubes. Sumll blood-vesscid ramify 
iu tbe watitt uf th« iitr-celbt. The wuIIa of tlio aireells are pxtrpaiely 
Uiiii and consist of two layt^rs; the blood vawtels, being bcttreea the 
Irtycra, thiia ex|K)«e a surface to the air id two diflfei'cDt cells. The 
air-oells are the cimiiummation of tlie iutricate stractaree fonitiag the 
respiratory apparatus. They are of (irime importance, all the rest be- 
ing comidemvtitarx. It is witbio these cells that is accomidisheil all that 
coui^titutc:! tbe iilLiiitatcre«alt of the function (if n-.s|tirat:i*>ii. It is lirre 
IbH (exchange nf gases takes place. As before stated, the walls of the 
oells are very thin; so, also, are the walls of the blood-vessels. Tl)n>ngh 
tbe-'W walls escapes from the blood the carbonic-acid gns that bus l>een 
abAurbtnl by tbe blood in its circulation tbmngh the ditlerviit purls of 
tbe body ; and through these walls is absorbed by tbe blood, from the 
air ID the air cells, tbe orygea gas which is the life-giviog element of 
the tttniospliere. 

Thtougbout tbe substance of the lungs the bronchial tubes tennloaUj 
in tbo air-cells. Blood-vessels are iu every part; likewise lymphatlo' 
TMselK and nerves, which reqntre no more than mention in this pnprr. 

T»i give a rude ideu of tbe !irninf(*^monL of tho respiratory appiirntus 
as a wbole, we may jinf&talily compare it to a tree, for tbe want of a 
t«r illastration. Say that all the respiratory tract Ooin (he naaidll 
nprnings back to the pharynx an< the riMils in the grouiul ; the larynx 
may be com|>ared tu the large part of the trunk Just ubove the earth j 
the windpipe will represent the body or the bole of the tree ; the right 
and left liroiichi maybe consideretl the first two or liirgeHt limbN] 
tht-* brouebial tubes are then comparable to all th^ n-st of the lliiilis, 
brancbcs and twigs, gradually becoming nioallrr and liniiicldnu nut 
more freiiuently, until the smallest twigs terminate by bavintc a leaf 
apiieniled; and to complete the coinpannoii we mny as well Hay the

CONGESTION OP THE LUHOS.

flaoiniiitiou. OonjZPHtion in eHsentially an excess of bloo<l in tbe veHRels

exists as an independent affection, U generally canwd by overexertion 
when tiie animal is not in a lit oouditiou to undergo more tban BiotI«r- 
otc exercise. 

Tha methods practiced by tbe rraincrs of rnnning and trotting borses 
will give an idra of wbat is l^Tiiicd " |iuttiiig u borwe iti coiidiliMu " to

gestion of tbe lungs if be is otherwise bealthy. On the otbcr band, if 
tbe borse is kept in the stable for the pnrpo&e of laying on ful or for 
want of Kometbing to do, the muscular syBtem becomes soft, aad tbe 
borse is not in condition to stnnd thoAevere exertion of going fast or 
far, no matter bow bealtby bo may l>c id otbcr rAspects. If rach a 
borae be gi%-eu a hard ride or drire, be may start off in high spirits, 
bnt M>»ii becomes exhausted, and if he is pushed he will slacken bis 
pact:, show a deniru to stop, and may stagger or even fall. Examina-

bntugbt ahcnitf Tbe heart and muscles were not aocastomed to the 
sudden and severe stTain put upon them; the heart became anable to ■ 
I>erform its work; tbo blood accnmalnted in tbe veseels of tbe lungs, ^ 
wbieli eventually became engorged with the stagnated blood, consti- 
tuting coiigeKtiou of the lungs. 

The animal, after having nodergone severe exertion, may not exhibit 
any nlannlng symptoms until retarnod to tbe stable; then be will be 
iiutiLi>d Hlanding with bis head flown, legs Kpread out, the eyes wildly 
stilling or dull and sonkeu. The breathing is very rapid and almost 
gasping, tbe body is covered with iiersptratioa io most cases, which, 
however, niny goon evaporate, leaving the snrfitco of the body nod the 
legFt and uarM cold; the breathing in bntli utHloniinat and thonuric; ihs

If the pulso ciui be felt at all it will be found licAting very h^nently,

APOPLEXY OF THE LtrSOS. 

This is bnt nnotber term for congestion of tbo Inngs, and for practi- 
cal puqto&ea tieedH uo 8]iecial dirxirriptioti, except to rtimurk ihat when a 
hemorrha^re occurs during the congested state of the lungs the blood 
escapes froto the raptured vessels and extravitsates tuto the lung tissue. 
Such vaHes are calle<l pulmoniiry aiwplesy, and usually uocur limiag 
the course of some specific dlsenso. 

PKEI'MONIA— LUNO PKTT.n, 

Pneninonia may attack both lungs, but as a general mie nnn long 
only i» aflVctcd, aud in the great miyoritj of caws it is the right lung. 
The atrcelU are the jKirts alle<-l«d [>rincipally, but the minute branches 
of the bronchial tubes always, to a greater or less extent, are involved 
in the iniliiminalion. Iiithunruatlon of the lungs occurs in three priuci* 
pill varietit'it, but in a work of this kind there is no necessity to dis- 
critninnte, and therefurt? the disease will be described under a oomnKlD 
head, it already has been nieutioiied that pueuniuniamuy l»e compli- 
cated wilh bronchitis, and it; will licreiifter be poiuled out that it Is very 
oomuonly complicated with pleurisy. In this article the disi-unc will 
be considered luaiuly as an iude]>eudeut aflectlou, aud its complicatjoa* 
will be nmr« fully descritied under i<eparate heads. 

The iudauimatiou umially begiuH in thu lower part of tlie \ax\g and 
oxtenils upwards. The tiret singe of the disease consists of congestion 
or engorgement of the bloml-wsst-lH. and if Ihiscoudllion eon tinuea thai 
blood exudes from the vessels into the adjacent, lung tissue } if ruptore 
of small blood- voH8«<l8 occurs ilieto will bo extra vattat ions of blood in 
the contiguous parts. The fluids thus escapiug collect in the air-eells 
and in the miinite branches of the little bronchial tubes, and, bix'Oming 
coagulated there, romplflely b1oi:k up the cells and exclude the air. 

lu this condition the lung i» increased in volume and is much heavier, 
and will sink in water. The pleura covering the affected jiartsia al- 
ways more or less intlauied. A coutiunance of the foregoing phenom- 
ena Is marked by a furtlier esccnpe of the eoustitnents nf the blood, aud 
a change in the niembiaue of the cells, which become hwuIIcu. The 
cxadate that tlllH the air-cellA and minute bronchial branches undergoes 
disintegration, and is converted into ti fatty material. The waUtj of tbe 
celts almost Invariably remain unaltered. 

It must not bo imagined that (he foregoing changes take place in

be allowed. Much benelit may be deriveil from hot applications to the 
sides of the cheat if the facilities are at band to apply them. If the 
weather be not too cold, and if the animal is in a comfortable stable, the 
following method may be tried : Have a tub of hot water handy to the 
stable door ; !iouk a woolen blanket in the water, then quickly wring as 
much water as possible out of it and wrap it around the chest. See 
that it (its clotwly to the ttkiu ; do not allow it to sag down so that air

should be quickly rubbed as dry as possible, an application of MuitneuC 
rubbod over the wet part, and a dry blanket snugly fitted over the 
animal ; and especial care should be taken to cover with it the wut part 
of the skin. If tho hot applications appear to benefit, they may be 
tried on three or four consecutive days. ITtitess every facility aud cir-

not attempt it If the weather is very cold, or any of the details are

It is possible that oases ocuur that may be slightly benefited by bleed- 
ing, but the non-cxiMjrt is certainly unable to dlscrlmluate iu such io- 
atancex, and therefore bloodletting should never be practiced. Indeed^ 
many veterinary practitioners of great experience wholly condemn the 
practice of bleeding in pneumonia, as i>oftitively hnrtfa). Wbeo paea- 
monia follows another disease the system is always more or less debitt- 
tBted, and n^qnirea the careful use of stimulants from the beginutog; 
to still furllier weaken the animal by tapping him (if the expr(^ssion 
may bo used), and letting e-seajM} in a stream the very source of his 
remaining strength, is one of the most effectual methods of retarding 
recovery, ovcu if it doea not hasten a fatal termination.

If the horse becomes very much dcbilitateil, stimulants of o more pro-

There are cases where Hcdativcji are undoubtedly beneficial, bat a

Ryinptnms are studied beforebaod. The very HrKt atage Is a eonKentei) 
state of the blooil vessels in the paria affected ; the surface of the mrm- 
hrane becomes dry and ruuKliened (this fact will la.- attain referred to 
when the symptoms are described). This dry condition is followed, after 
a certain jwriod, by au effusiau of fluid, tb.it is, more Quid than usual It 
thrown off by the membrane when in a diseased condition. This fluid 
accumulates in the Hpaee betwwu Ibt! hiutrs and tbii walla of the tibt'Kt, 
constituting bydrothorai, or dropsy of the chest. Thin fluid may 
undergo certain changes; iu it float coagulated masses called llbrin.

Treatment. — TliiM varies very littk^ from Lbo treatmiiut of brouchilis 
and iMieatnooia, but as frequently stated heretofore, pleorisy ia &o lia- 
ble to l>e complicated with either of tho disoascA named, tfa« varintion 
in the treatment may b« considered a» merely a<yuiict treatment of tlie 
pli'iiTitic coiiiplicntioa. 

The iustnictioiis in regard to tb« geooral maoa^meat of broDcbitii 
and pnenroouia mnat be adhered to in the treatment of pleuriHy. Com- 
fortable qiiarterH, ])ure air, irarm clolbiui,''tu tbe body and bandages to 
tho legs, a pleutiful supply of pure cold water, the laxative food, etc., 
in thia case are equally ncceaftary and efficaciona. Tbo hot applica- 
tions applied to the cho^t o^ dirpnttnl in tlie treiitment of pneumonia 
are verj- I>eiielicial in pli-uriKy, and should bo kept up while the symp- 
toms show tbe animal to Ite in pain. 

During; the first few day», wbou [tain ia mairifcsted by restlesso 
do not npply (be liriimeut to the xides of the ebeiit, as it will not onlj^ 
irritate tbe nnimal and increase tbe resflessne^a but will beiKlitcn tli 
fever ae well. After four or fite days, wtii-u tbe symptoms show thai; 
tbe acate stage has somewhat subsided, tbe Uniment may be well 
rubbed over tbo alfeetcd iiart with boneQt, as It will greatly promote 
the absorpuon of the elTiiHion. Tbe application may be repeated on al- 
ternate days until several applications have been madek From the bo- 
ginning tbe following drench sliould be gtvcn every six boars: Sola- 
tion of tho ncetate of uninioniiL, 3 ounces; spirits of nitrous etlier, X 
outice; bicarbonate of potassiom, 3 drams; water, 1 pint. ■ 

If the patient becomes debilitated tbe «trmulaiiU as prescribed for 
pneumonia should bi3 ascd according to the same dircctioua The«amo 
attention should bo given to tbe diet. If the animal will partake of 
ibe bran mashes, scalded oats, and grass, it is the best, but if he nyj 
fkiaes the laxative diet then be sliould be tried with diHereut kiiidtt 
food, and allowed whicbovur kind be desires. 

lu tbe beginning of tbo attack, if tbo pain is Mvore, csnsiDg the aoi^ 
mal to lie down or paw, tbo following drench should be given: Tiuct 
ure of upiuui, 2 uuucuh; raw llnMH^d oil, 12 uuiicl-s. If tbo pain cot 
tiuuea, tbe tincture of opium may be re|>eated within (bur or tlve boui

aoooant of tho degeneration of the walls of the ajr>cclls, and also on 
account of tho paralysis of muscular tissue before mentioned. Tho air

but no bid effect followed the admUsion uf air iuto tho thoraclo cav-

tKaliof Toanda generally, and a speedy and perfect recorcry waa made. 
Tbenoond may oot penetrate the plctira ; in such eases no great harm

Tnnips— SPASM OP the DiApna&cu. 

"ThQmp«''i8 gcnemlly thought to be, by tbe inexperienced, a 
pitation of the tivarU While it is true that i>alpitatton of tho heart is 
Bomctime<^ called " ihumps,^ it most not becoofouadeU with tbe affe 
tion under coiiKitlfraliou. 

Iu the beginning of this article on the diseases of the organs of 
piration ihedii^phrat^n \Tas brieiiy refurrvd toaa the principal and 
sential nutsulc of respiration. SpasuKxlio or irreK"'^ contiactions of 
itinmiuiare uiauifestod by what is familiarly known as hlocouglu. 
Thumps in the horse is identical with hiccoughs iu man, alUiongb tbe 
pccniiar mimo is not made in tlio throat of tbe liorso in all eases. 

Thcro should bo no difficulty in distingaisUiug this afTectiou from pal- 
pitation of the heart. Tho Jerky lootion nlTocta the whole body, and is 
not conQned to the region of the hearts If one hand is plac^ on tbo 
body at about tlio middle of the last rib, whilo tho other hand is pli 
o\-er tbo heart behind the left elbow it will be easily demonstrated tb 
thero is uo oounectiou between the thumping or Jerking of the di 
phrngm and the beating of the hmrt. If the ear is ptacetl ag;iiuat 
body it will bo disoorered that tht) sound is made iio.ttcrior to the regioi 
of tho heart. In fact, when the animal is alTected wilb spasms of tl 
diaphragm the beating of the heart is nsnaliy much weaker and h 
pteceptible than natural. Thumps is produced by tbe same cat 
which produce congestion of the lungs, and in often sotm in connection 
with tho latter disease. If not roliored, death usually results from con- 
geutiun oftbe lungs, us Uie breatliiog is interfered with by tbe inordi- 
nate action of this tho principal muscle of inspinition so much that 
pruiwr aeration of the blood can not take place. Tift treatment should 
be precisely the same aa prescribed for congestion of tbe lungs. 

BUPTUBE OF TUB SlAPHBAGU. 

Fott mortem examinations reveal o groat many instances of rnptar« 
of tbe diaphragm. It ia the general opinion among Tctorlnariaus tli^ 
tliia takes place after death, and is due to tho generation of gases in 
tbe decomposing carcass, which distood the intestjnoe 90 that tho dia^ 
pbragm is rupturwl by tho great pre-ssuro against it. Of coarse it is 
possible for it to hapi>«u before death and by straugulatiug the knuckle 
of iutriitino that may be in the rupture cause death; but tUere are no 
symptoms by which it miiy bo diagnosed. 



DISEASES OF THE GENERATIVE ORGANS. 



By Or. JAMES LAW. P. R. C. V. 3.. 



COltOBSTION AMD ISPI.AMM ATION or IIUS TESTICLES— OKOmTie. 

Inthcprimo of life, )nin{:;oronBlieaUti, and on sliinnlAting fonil Ktnll- 
ioiLs are subject to congCKtiuii of tli(^ (estiirlas, wliieli bei^omo Bwoll«-n, 
hot, aod tender, but idtbont any active inllaniiuatiaa. A reduction of 
tlio grain in tbe feed, Uie administrntjon of 1 or 2 onnoce of GluuLer 
salts daily in tho foo*I, and tho batliiof; of tlio affected organs daily 
Willi tfpid water or alum water will usaally restore tlieni to a bealihy 
condition. 

WbcD tbe factors prodacing congestion aro extraordinarily potent, 
wben tticro baa been frequent copalation nnd hea\T grain ree^ling, 
wben ttie wealber is warm and tbe animal bas bad liLllo exorcise, and 
wben the proximity of otUerliorses or mares excite tbe generative in* 
tinct nitfaoal gnitincatinn, thi5 oon^Htinn may gniw to actnal inflaoi- 
kaiion. Among tbo other causea of orobitis aro blowtt and penetrating 
wounds iuplieating the tettticlee, abrasions of tbe ecnitnm by a cbaln 
or ro[>e passing inside the tbigb, contasions and frictions on tbe gland 
under rapid pncc^ or bravy draught, oomprusxian of tbo blood>TCSsels of 
the 6iH>ruiatic cord by tbe ingainal ring under the »anie eircumytances, 
and Bnally, aynipatJietic dUturbanco in cases of disease of tbe kidneys, 
bladder, or urethra. Stimnlants of the generative functions, like rue, 
savin, taosy, cant bar idt'ii, and dauiiaua may also be accessory causes of 
congestion and intlaDaination. Finally, certain specific diseases lilie 
mal du co'iti glanders, and tobcroalosis, localize<l in tbe testicles, vtil 
ouise inflammation. Apart from octaal wounds of tbe parts tbe symp- 
toiu of orcliitis are swelliug, beat, and tonderiio-sj of tlie tcaticlea, 
straddling with tbe hind legs alike lu standing and walking, stiffness 
and dragging of the bind limbH or of the limb on tbe affected side, 
■rcblng of the loins, Hbdouiinal paiu, manifested by glancing back at 
^be Bank, with more or less fever, elevatc<l body temperature, accder. 
sted palse and breathing, ioappotenoo, and dullness. In bad cases tbe 
■canty nrioo may be reddish and tbe swelling may extend to the sklu 
and envelopes of the testicle, wbicb may become thickened and doughy, 
piltiog on proMure. The swelling may be so mucti greater tn tlio con-

Matter (abscess) may bo recognized by tlie presence of a soft spot, 
wburo pn;.ssuro witU two lingers will detect fluctuation ttom one \a 
the otbcr. When tliere is liquid exudation into the scrotum, or sack, 
SactuatiOQ may also bo felt, but tbo liquid can be made out to be 
around the testicle and can be pressed up into tbo abdomen tbroagh 
the inguinal canal. When abscess occnrs in tlio cord the matter uij* 
escape into the scrotal sack nud cavity of the abdomen and pya^tnia 
may follow. 

Treatment consists in perfect i-estand riuietude, tbe admiuistrntionof 
a purgative (1 poaudtolj pounds Glauber's salts), and the local appU- 
cation ofnn astringent lotion (acetate of lead 3 dniuis, extract of bell> 
donn& 2 drams, and vnter 1 quart) upon sofX rags or cotton wool, kept 
la oontjict with tbe part by a fiuiipeusory baudago. TUU bandage, of 
great mine for support, may be made nearly triangnlar and tied to a 
girth around the loiiis and to the upper part of the same surcingle by 
ttro bands carried backward and upward between tbo thighs. In sovoro 
eases scariBcalioas one-fourth inch deep serve to relievo vascular ten- 
sion. "When abscess is threatened its formation may be favore<l by 
warm fumi^ntations or [wulticcs, sod on the occurrence of flactnatioQ 
tbe knife may be employed to give free escape to the pus. Tbe rcsalt- 
ing cavity may tie injected daily with a weak carbolio acid lotion, 
salol may l>e introducetl. Tbe same agents may be osed on a gland! 
threatened with gnngrcne, but its prompt removal by castration is to 
be preferred, antiseptics being applied freely to tbe resulting cavitj.

This is an enlarged and iudurated conditiOD of tbe gland resoltioi 
from chronic iullammatiou, though it is often associated with a speci 
deposit like glanders. In this oondition tbe natural stmotnre of tbe 
gland has given place to embryonal tissue (small, ronnd oelU, witli a 
few fibrons bundles), and its restoration to health is very inprobable^ 
Apart 6vm active indammation, it m.iy increase very slowly. Tbe dis- 
eased testicle is enlarged, firm, non-elastic, and comparatively inscasi-

This maybe mercljaii accoiiipaiiimeiit of dropsy of tbc abdomen, the 
cavity of wbicb is voutiuuoiu witti that of tliu scrotum in tiorses. It 
may be tbe result, however, of local disooso ia the testicle, spermatic 
conl, or ttaUh of the sack. 

Tbe Htfmptomi arc enlargement of the scrotum, and fluctuation udcIct 
the Qogerg, the testicle being recognized as floating in water. Uy press- 
ure the liquid ia forced, in a .slow stream, and witli a porcoptiblo thrill, 
into the abdomen. Sometimes the conl, or the scrotum, are thickened 
and pit on jiressnrc. 

Treatmertt may be the same as for ascites, yet ivhen the effusiou haa 
resalted from inflammatian of tlie testicle or cord, astringent applicattODB 
(ohalk and viuegar) may bo applied, to these. Then if th<> liquid is not 
re-abaorbed underdinretics and tonics, it may be drawn off ttirongb the 
Qozzio of a hypodoriuic sjTinge, which has been flrst passed throngh

and this failing castration may be resorted to. 

ABNOBSAL NUMBEll OK TESTICLES. 

Sometimes one or both testicles are wanting; in most such casea, 
however, they are merely partially developed, and retained in the in> 
gntual cnnal, or the abdomen (crj-ptorchid). In rare Ciisen there may 
boa third testicle, the imiraal becoming to this extent a donble monster. 
Teeth, hair, and other indications of a second fcetus have likewise been 
fonud Id the testicle, or scrotum. 

OEaeNEBATIOK OP THE TESTI0LE3. 

Tbe testicles may become tbe eeat of fibrous, calcircona, fatty, carti- 
IftgtuouH, or cystic dcgencnition, for all of which the appropriate trcnt- 
meut is castration. They al><o become the se.it of cancer, glanders, or 
tuberculous, and castration is requisite, though with less hope of ar- 
restiuff the disease. Finally tlicy may become infested with oystio 
taiic-vurms, or the arm«l rouud wavm {tderostomwn equinumj.

come tbe seat of effuHion of blood from one or more rnptored blood- 
ressclH. This gives rise to a mure or kwt extensive Hwclling on one or 
more sides, followed by some heat and iiiQamuiation, and on recovery a 
eerious curviug of the orgau. The trcatmeut iu the early stages may 
be tbe applioatioo of lotiona, of alum, or other astringents, to limit the

OASXBATION OF 8TALLI0KS. 

Tbis ia nsnally done at one year old, bnt may b« accompHsbed at a 
few weeks old, at tbe expense of an imperfect dovclopmeat of the fore 
parta. The Rimplidty and safety of tlio oiieratioii are greatest in tLe 
youug. Tbt; delay till two, three, or foar years old will secure a better 
derelopment and carriage of the fore parte. Tbo esseatial port o( 
casttatioo is tUo safe removal or dostraction of the testicle and the 
arrest or prevvtitiou of .blcvdiiig from tlie Hpermalic arl-ery found in 
tbe anterior pari of the cord. Into the mnoy methods of accomplish* 
Ing this, liiuited Bpacc forbids us to enter here, so that the mctliod moat 
commonly adopted, castration by clamps, will alone be noticed. Tbe 
animal having been thrown on his left side, and the right hind foot 
drawn np on the shoulder, the exposed Bcrotum, penis, and sheatb are 
vaahed with .soap aud water, auy coucrotiou of auburn being carefully 
removed from the bilocular cavity in the end of the i^enis. The left 
spermatic cord, just above the testielc, is now seized in the left hand, 
so as to render the skiu tense over tbe stone, and tbe right hand, armed 
with the knife, makes an incision from before bachwnrd, about three- 
foarths of an inch from and parallel to the median line between tbe 
thighs, deep enough to 6xx>ose the testicle aud long enough to allow 
that orgau to start out through the skin. At the moment of makiug 
this incision the left hand miist^ grasp the cord very firmly, otherwise 
the sudden rotractioD of the testicle by tbo crcmastcr masole may draw 
it out of tbe hand aud upvranls through the canal nnd even into tbe 
abdomen. In a few seconds, when the struggle aud retraction hare 
ceasc*l, the knife is inserte<l through the cord, between its anterior and 
posterior portions aud tbe latter, the ouo which the muscle rotracte, ia 
eut completely through. The testicle will now bang limp and there is 
no longer any tendency to retraction. It should bo pulled down until 
it will uo longer bang loose below tbo wound aud the dumjis applied 
aroQud the still attached portion of the cord, close up to the skin. Tbo 
Clamps, which may bo mndo of auy tough wood, are groovetl along the 
center of the surfaces opposed to each other, thereby fulftlUng two im- 
portant indtoations, (a) enabling the clamps to hold more securely and 
(6) providing for the application of an antiseptic to the cord. For tJiia 
puqiose a dram of sulphate of copper may be mixed with au ounce of 
lard nnd pressed into the groove in the fiiee of each claaip. In apply- 
ing the clamp over the cord it shoold be drawn so close with pioeersas 
to press out all blood Crom the compressed cord and destroy its vitali^f 
and the cord applied upon tbe couipressing clamps should be bo hard- 
twined that it will not stretch later aud slacken tbe hold. When tbe 
damp has been fixed tbe tejiticlu is cat ot£ ono-half to 1 lucb below it,

may bo dangeroos when due precaatlon has not been taken to prcrcnt 
it'. In such case the stump of the cord shouUl bo Koti{;ht for tind the

wonnd in the shin, whence it derives an increased supply of blood, 
and is thereby stimulated to innro ntpid swelling. The subject walks 
stiffly, wiUi straddling giiit', loses apjietitc, and has a rapid pulse and 
high ferer. Gxamiualion of the wound discloses the partial closore of 
tlie skin wound, and tho protrusion from, its lips of the end of the cordi 
re<l, tense, and varying in size from n hazvl-uut upward. If there is 

00 material awelllug and little protrusiou the wound may be enlarged 
with tho knife and the eud of the cord broken loose front auy cooaeo- 
tion Willi the skin, and pushed up inside. If tho swclliog is larger the 
mass constitutes a tumor, aud must be removed. (See below.) 

SWELLING OF TBS SSEATH, TEinS, A>'D ABDOMEK, 

This occurs in certain nnhealLhy Ktates of tho system, in anhealtby 
Bcasous, as the result of oi>eratitig without cleansiug the sheath and 
penis, or of keeping the subject iu a fdthy, impure building, as the 
result of infectiug the wound by bands or instramcuts bearing eeptic 
bacteria, or as the result of premature closure of the wound, and im- 
prisonment of matt4T. 

Pure air and cleanliness of groin uud wound are to be secured.

Formerly tlioopcratJon wii.s estou.'^ivcly practiced iu Euroiu-, the incinKiii 
being made through tUo Hank, and n, large proportion of tbo BubjecU 
pcrisbing. By oporatitig tUroiigb tlio vagiua tlie risk can be largely 
obviated, as tlio danger of oDliOiiltliy inHaniniatiotL ia the wound ii 
greatly' lessened. Tfao animal &liau]d be llxcd ia a trerls, nith each foot 
flxed to a post and a aliug placed under the body, or, better, It tea; be 
tbro^rn and put under cblorororm. The manual operation demandi 
BlKCial professioDRl knowledge and BkJU, bnt it consists essentialljr ia 
making an opening tliroagli tlteroof of the vagiiiajust above the neck 
of the nouib, then followiug vith the baud each lioru of the vomb 
nntil the ovary on that eido ia reached and grasped between the lipa of 
forceps and twisted off. It might bo torn off by an ecrasour eei>ecLall5 
conslruclcd for the purj'OSO. Tbo straining that follows the operation 
may bo chcclii-d by ounce doses of laudanani, and any risk of protra- 
siou of tbo bowels may 1>o obviated by applying the truss advised to 
prevent eversion of the womb. To further prevent the pressnro of 
the abdominal contents against the vaginal wound the marc should 
1>e tied short aud high for twenty-four or forty-eight hours, after which 
I linvo found it best to remove tlio truss ond allow tho privilege of 
lying down. Another Im]>ortant point Is to give bran mashea and 
other laxative diet only, and in moderate quantity, for a fortnight, and 
to uuload tho rectum by copious tiijccttons of \ranu water in case it 
should threaten to become impacted. 

STEKILITY. 

Sterilily may be in the male or in the female. If duo to the Ptalltuii, 
then all the mares pat to him remain barren ; if due to the mare, sho 
alone fails to conceive. 

in the Btalliou sterility may be duo to tho following causes : (a) Im- 
perfect deveh>pmeut of tlie testicles, as in canc^ in which they aro re- 
tained within the abdomen} (b) inflammatioa of tho testicles, resulting 
in iudnration; (c) fatty degeneration of tho testicles, in stallions lib- 
erally fed on starchy food and not suOicicntly exercised; (d) fatty 
degencmtiou of tho cxcrotori.' duct:^ of the testicles {rasa de/erentitt)i 
(«) inflammation or ulceration of these ducts ; (/) iuflammalloii or olcer- 
ation of tho mucous mcmbrnno covering the penis; {g) injuries to the 
penis from blowa (often cauBintj pnraly.sis); (h) wnrty growths on tho 
end of the peuie; (i) tumors of other kinds (largely pigmentary) af- 
fecting the testicles or penis; (j) nervous diseases which abolish tbb 
sexual apiietite, or thai control over tho muscles which is essential to 
the act of coition; (itj azotnria with rc-siUting weakness or paralysis 
of the muscles of the loins or the firout of tho thigh (above the stiSe); 
(I) ossiSeation (anchylosis) of the Joints of the back or loins, which 
renders tho animal unable to rear or mount; (Nt) spavins, riogboac

or other painfal aCTcclfons of tlie hind limbs, tlie i>a{n of nliich in

element (BpermatoKoa). In the other examples the secretion may bo 
perfect in kind and amouut, bnt as copulation is prcreotcd it can not 
Tvaeh nnd iuipregnalo the ovum. 

In the mnrc barreniie^s is eqiinlly iliio to a variety of eauses. Xn a 
number of breeding studs the proportion of sterile mares lias varied 
from 20 to 40 per cent. It may be duo to: (a) Imt^erfcct development 
of the ovary and non-mnturntion of ova ; {b) eyatio or other tumors of 
the ovary ; (c) fatty dege in? ration of the ovary in very obese, pampered 
marea; (d) fatty degeneration of the excretory tubes of tlio ovaries 
(rnllopiau tubes); [e) catarrh of the n-omb, '^'itb tituco-pnrulent Uia- 
charge; (/) Irritable conditiou of the womb, with profnso eccrottoD, 
Btroining, and ejertioii of the semen; [g) nervous irritability, leading 
to the name expulsion of the male clemcut; (A) bigh condition (pktiiora) 
vitb profuse itecretlon and excitement; (i) lowcoiulition with imperfect 
maturation of tlie ovn and lack of sexual desire; (j) poor feeding, over- 
work, and chronic debilitatiag diseasea, as leading to the condition just 
named; (it) closure of the neck of the womb, temporarily by spasm, or 
l>enn»nently by inflaiamation and induration; (0 closure of the entrance 
to tlie vayiiia tlirough imperfomte hymen, a. rare tUoiigh not unknown 
oontlitioii in the mare; (iii) acquired indisposition to breed, fteen in old, 
banl worked marcs, which are first put to tlie atallion when aged; (n) 
cbangf^ of climate has repeatedly been followed by barronnesn; (o) Uy- 
bridity, wbioh in male and female alike, ueuully entails sterility. 

Tbo treatment of tbo mi\jority of tUese conditions will be found dealt 
with in other parts of this work, so that it is only necessary here to 
name tbem as causes. Some, however, must bo spcuitilly rftf<*rre<l to in 
this place. Stnliions with uudescended testicles are beyond the reach 
of medicine, and ^hoold bo castrated and devoted to other uses. Id- 
dumtctl testfclcH may KOmetimcs l»e remedied iti tlie early fltageM by 
smt-nring vitb a weak iodine ointment daily for a length of time, aud 
ftt (he same time invigoratjn^ the system by liberal feeding and judl- 
cinus work. Fatty liogeneration is best met by an albnminoid diet 
(whi'at bran, cotton-seed me:d, rape cake) and L'oustanI, well regulated 
work. Sacelmrine, starchy and fatty food (potatoes, wheat, corn, etc.) 
are to bo specially avoided. In tbo tnaro one difieased and irritable 
ovnry sbnuld be removed, to do awiiy uitb the resnlting excitability of 
tbo remainder of tUo generative organa. An irritable womb, with fre- 
quent Rtraining and the ejection of a prafnse secretion, may sonietimes 
be corrected by a restricted diet and full but well regulated work. 
Even fatigue will act beut'lit^ially in some such raaea, hvuva the practice 
of the Arab riding his mare to exhnnstion just before service. The

weather. IT heat merely per-sists an uriilau Ipiigtli of time after service, 
or if it re-appcars slimtlj' after, iu warm wcaUier and in a compara- 
tively idle mare, on good reeding, it js less significant, while the per* 
^atsQt abseoM of heat auder such coaditions tnajr be asoally accepted 
•« proof of conception. 

Ad unwonted eentleuess and docility od the partofa previously irrita- 
ble or vicious mare, and snperveiiing ou service, is an excellent iudica- 
t4on of pre^nancj, llie gcucrativo instinct wlticli caus«<t the excitement 
having been satisfied. 

An iuurease of fat, with softness and flabbinesM of miisete, a loss of 
energy, iudispoaition for active work, a manifestation of Inziiieaa, in- 
dee<l, and of btigue early and easily induced, when preceded by service, 
will asnally imply couoeption. 

Bnlargemetit of lUe abdomen, es|icc]ally in its lower third, with slight 
filling in Iwoeath the loins nnd hollowness of the back nro siRniflcant 
ayoiiitom^ though they may be entirely absent'. Swclliug ami Qrmuitss 
of thojndder, with the smoothing out of its wrinkles, is a saggcstive 
^gOf even though it api>ears only at intervals (luring gestation. 

A ste:uly increase in weight (1^ pounds daily) about the fonrth or 
fifth month is a osefnl indication of pregnancy. So is a swollen and red 
or binlsh-reii appeiranae of the vaginal mucous membrane. 

From the scveii Ih or eighth month ouwai-d the foal may bo felt by tha 
liand (palm or knuckles) pressed into the abdomen in front of the left 
•tide. The sudden push displaces the foid townnl the opposite side of 
the womb, and as it Ooats back its hard body is felt to strike against 
the hand. If the pressure is maintained the movements of the li^'e foat 
are feU, and espeeiully in the morning nnd after a drink of cold water, 
or daring feeding. A drink of cold witter will often stimulate the fa-tas 
to movements that may be seen by the eye, but mi excess of iced water 
may prove injurious, even to the causing of abortion. Cold water 
i]a«fae«l on the belty has a similar effect ou the foctns and equally ea. 
dangers abortion. 

ExamioAtiou of the ntems with the oiled hand iiitrodnced into tbo 
rectum It still more satisfactory, and if caatioosly conducted no mora 
dangerous. The rectum must be Urst emptied iind then llie Imnd car- 
rinl fcirwani until it reaches the front edge of the pelvic bones below, 
■ad pressed dowuwanl to ascertain the siiso and outline of the womb. 
Iu the unimpregoaled state the vagina and womb can bo felt as a sin- 
gle roniiileO tube, dividing in front to two smiiller tubes (the bonis of 
tbtt womb). In the pregnant mare not only the body of the womb is 
-ged, but still more so one of the honi.t (right or left'), and on com* 
on the latter is found to contain a bard, uoUular body, lloatiug In 
id, whii^h in the latter half of gestation may be stimulated bygen- 
tU preasnre to manifest s|x)nt»neous movements. By this method the 
luoo of the feotus may be determined as early as the third month.

DtTEi.TION OF PREGNANCY. 

Mares usually ^ about eleven months with young, though flret pr 
nancies often Inst n year. Foals have lived when born at tho tht 
bundrvdth day, so with olherM carried till the four Imndredtli day^ 
With the longer pregnancies there is a greater probability of male off* ' 
sprinj;. 

BYOlEIfE 01' THK rBKaHAMT tlAKB.

The pregnant mare should not bo exposed to tOJisins by a yoonj; and 
ardent stallion, uor should she be overworked or fatigued, particularly 
under the saddle or on oneveo ground. Yet exercise is beneficial to 
both mother and ofTripring, and in the absenco of moderate work Ibe 
breeding mure uliotdd be kept in a lot where she can tube exorcise ftt 
will. 

Tho food should bo liberal, but not fattening, oatJ», bran, sound hay, 
and other foods rich in tbe principles which form ticsh and bone being 
especially Indicated, All aliments that tend to indigestion aro to be 
especially avoided. Thus rank, aqueous, rapidly grown grass and other— 
green fixid, partially ripe rye grass, millet^ TTDngarian grass, vetches^ 
iwase, beans, or maize aro objectionablCt as is over-ripe fibrous, innn-" 
tritious bay, or that which has been injured and rendered musty by 
vot, or that which isinfested with smut or ergot. Food that tends to cos- 
tivenes.s should be avoided. Water givrn often, and at a tcmprraluro 
considerably above freezing, will avoid thcdaugcrsof indigestions und, 
abortions which result fbom taking too much Ice-cold water at one ttmi 
Very cohl or frozen food is objectionnble in tho same sense. Severe' 
surgical operations aud medicines that act violently on the womb, bow* 
els, or kidneys aro tobearoided nsbeinglinble to canse abortion. Co[ 
stipntion should bo corrected, if possible, by bran uasbeSf carrots, oi 
beetK, seconded by cxcereise, and if a meilicinal laxative is required IE 
should be olive oil or other equally bland agent.

EXTUA-UTEEISE OESTATIOK. 

t is rare in the domestic Hiiimal» to find the Aetus developed else- 
where tbau in tbo womb. Tiie exceptional forms are thwjo in which 
the speru) of tlie male, making its way tlirough the womb and Fallopian 
tabes, impregnates the ovum prior to its esciipi-, and in which the now 
vitalised and growiu}: ovum, by reason of its gradually increajjiiig nize, 
becomes iniprisonett and fails to cscajw iuto the womb. The arrest of 
the ovum may be iu the sabstance of the ovary itself {ovarian preg- 
nancy), iu Ibo Fallopian tube (tubal pregnancy), or when by its coutiu- 
QODS eolargemeot it has ruptured its envelopes so that it escapes into' 
tbe cavity of the nbflomon, it may become attached to any part of tbo 
■eirous membrnue and draw its nourishment directly from that (abdoai- 
inal pregnancy). Iu all such cases there is an increase and enlarge- 
mcut oftbv ea]iillar3- blooJ-vpssels at the point to wliicb tbo cmbrjo 
has attached itsclfso as to furnish the needful nutriment for tbe grow- 
ing oOTitpnug. 

All appreciable symptoms are absent, unless from tbe death of 
Uio foitns, or its inlerferenco with normal functioris, general disonler 
and intlicatioQSOf parturition supervene. If these occur Inter than the 
natuml tlmu fur |}arturitiuu tbey are the more Hjgnillcaiit There may 
be genera) malaise, toss of appetite, elevated icmperatnre, acceleraterl 
palse, with or witbouL dtsUuct lubor paias. Examination with tbe

sofb stracturus becoming absorbed so as to leave ouly tbe bouea, or by

or IvHJ I'requeotlj' ttii-ougli tho vngina or rt-ctum. In the Iiittcr oases tlM 
best course is to favor tlin Qximkiion of tbe foat and to wanh out tbe re> 
suiting cavity with i\ solution of carbolic acid 1 part to water 50 parts. 
Thia may bo repeated daily. Whcro tlicrc is no spontaaeous opening 
it is injudtcons to iutcrfere, as tbo dauger from the retention of the 
fo&tus i.s less than 1h»t from Noptic fermeutations in the enormous fmtol

HOLES— A^flDIAN MONSTERS. 

These arc evidently prodacts of conception, in which tbo impregnated 
oviun haif fnile^I to develop naturally, aud presents only a ehautic masa 
of skin, hair, bones, muscles, etc., attached to the inner snrfac« of the 
wonil) by an umbilical cord, which in itself often abriveJed and wasteil. 
Thuy are usually accompauicd by a well-developed fcetos, so that thu 
mole may be looked ujton as a twin which has uudergouo arrest aud 
vitiation of development. They are expelled by tbe ordinary process 
of iiarlurittou, and u^iually, at tbe eamc time, witli the Qormally devel* 
oped offspring. 

CYSTIC DISEASE OP TITE WALLS OF THE WOMB— VEStCULAR MOLR. 

This condition nppears to be due to bypertropliy (enliirgement) of 
tbo villi ou the iuuer surface of tbo womb, which become greatly in- 
creased in number and hollowed out internally into a series of cysts or 
pouches containing liipiid. Unlike tho true luolc, lUercfore, they appear 
to be disoaKc of tbo maternal struuturu of the wuiub ratbej- than uf the 
product of cx)nception. Kodet, in a case of this bind, which had pro- 
duced active labor ]tainti, quieted tho disorder with aiiodyncH and securt^d 
a recovery. Where tbia is not available attempts may be made to re- 
move the masfi with tbe eorutieuror olbertvise, fullowiug this up wilb 
auLiscptic ii^jecUons, as advised auder tbe last beadiug. 

DBorSV OP THE WOUIl. 

This appcnrit aa a result of liomo dittcikso of the walls of tho womb, 
tut has been Ireinently observed after eesual congress, and has, there- 
fore, beou confounded witb pregnancy. Tbo symptoms are those of 
pregnancy, but without any movements of the i'oitas and without the 
detection of auy solid body tu the womb when o^camiued with tbe oiled 
band til the rectutu. At the end of lour or eight months there are 
signs of parturition or of frequent strniuing to pass urine, and after a 
time the liquid is discharged clear aud watery, or muddy, thick, and 
fetid. Tbo Laud introduced into tbe womb cau detect ucitber fLctiu

nor faptal tnembranc. If tlio neck of tlic iroinb closes llic liqiiiil may 
uccumtilate h second time, or even a Ibiril, if uo means are taken to 
correct tlie tendcQcy. Tbe best resort Is to remove any diseased product 
tliat may be fotiud attuctied to the walU of tliti wotub, and to inject it 
daily viith a wann solutioo of carbolic acid 2 drams, chloride of ziuo 
oDe lialf dram, waU'r, I qnait, A coursp of bitter touica, (jeuUim 3

OBOPSV OF THE AMltlOS. 

Tbia dilTcrs from fiiniplc dropsy of tUe ^roIub iu that tbe lliiid collecta { 
in Ibe fuuor of the tiro n'utcr bags (tbat in nliicli the foal iloats) aod 
oot in Uio otberwiHe void cavity of tlie womb. Thin uUection oau cio- 
cur only hi the prcgaaut animal, white dropsy of the wowli occurs in 
the uninipregnated. Tlie blood of tbo pregnant maro contains an ex- 
cess of water and a emallor proportion of nibuuicn and red globules, aud 
when this is still farther aggravated by ]>oor feetling, iind other unhy. 
gieoic couililioits, there is developed the tuadency to liquid transuda* 
tion from the vessels aud dropsy. As tlie watery condition of the blood 
increases with advauciuf; prcgaaocy, so dropsy of tbo amnios is a dis- 
ease of the last four or five months of gestation, 'flia abdomen is targe 
and )tendulo!is, and the swelling tluctiiatcii uiRler pre^.'siire, though tbe 
eoltil bmlyof the fnrtiis c-an still be felt to strike against tho hand 
pressed into tho Bwollinfr. If the tifttid is introduced into the vai^iua 
the womb ia found to lie tense ajid round, wHb the prtyecling nmndwl 
ueck effaced, while tho hand ia the rectum will detect tbe rounded 
swollen mans of tho womb so firm and tense that the body of tlie fu?!tn8 
can not be felt within it. The maro movoa weakly and unsteadily ou its 
Umbs, having diQicuIty iu Hujiportiug the great weight, and ia bad 
cases there may be Iosn of appetite, stocking (dropsy) of the bind limbs, 
difllcuUbreathing, aud uolicky pains. The tension may lead to abortion, 
or a slow, laborious parturition may occur at the usual time. 

Treatiuent consists ^ relieving the tension aud aecumulatiou by 
puncturing tbefo-tal tnembraue with a cnnuula and trocbar introduced 
tbroQgb the neck of tho wouib aud tho withdrawal of tbe trocbar so as 
to leave the canula ia titu. Or tbe uienibraTics may be punctured with 
the fiugfr and Ibc excess of liquid ullovrctl to escape. Tbiii may bring 
on ubortion, or the wonnd may close aud gestation continue to tbo fall 
term. A coarse of tonics (gentian root 2 drama, sulphate of iron 2 
drams, daily) will do much to fortify the system aud couuteract further 
excessive eHusiou. 



DROPHY OF THE I.T3IBS, PERIM^UM, AND IBDOMER. 

The diHiM>]tttion to dropsy often shows itself ia the hind and even in 
in the fore limbs, armind and beneath the vulva (purinu'iiui) and bu- 
auUi tbe abdomen aud chest. The affected parts are swolleu and pit

CONSTIPATtOX. 

Tills mny result from compression by tbe gravid ^omb, and is best 
corrected by a graduated allowaDco of boiled flaxseed. 

rARAI.VSIS. 

Tbe prcssnre on tbo nerve.s of tbo pelvis is liable to cause paralyfli" 
of tbc bind limbs, or in tbo mare of tbe nerve of sigbt. Tbeae arc ob- 
stinato until after parturition, wben tlioy recover spontaneously, or 
under a course of nux vomica and (locnlly) stimulating linimenU. 

PROLOKCtED ItETEKTION OP TITE raJTTO (POAL). 

Tq tbe ninro, tbongb far loss frequently Ibaa in tho cow, parturitioa 
may iiot Iw completcil at term, and tbc foal may continue to be carried 
in tbe womb for a number of montbs, to tbe serious, or even fatal in- 
jury of tbe ninre. Ilamou rcconis ooo case in nbtcb tbo mare died 
after carrying tbc fiPtas for seventeen montbs, and Oaillier a similar re- 
sult after it bad been carried In'onty-tiro inoutbs. In these cases tbe 
foDtua retained its uatnrnl form, bat in one reported by Oobicr, tlie 
Iwnes only wore left in tbo womb amid a mass of apparently pnriilenl 
tnatler. 

Tbo ca»iic iiiny be any effeotlve obstrnction to tbe act of parturition,

ABORTION. 

Abortion is, strictly speaking, the expulsion of the impregnated ovum 
at any jietiod from the date of impreguation until the foal can survive 
out of tbe womb. If tbe foal ia advanced enough to live it ia premature 
parturition, and iu the more this may occur aa early as tlio tenth month 
{three hundredth day). 

The luare may abort by reason of almost any cause that very pro- 
foiindty disturb'^ tlie system. Ueuce very violent luflamuiatious ofim* 
liurtanl internal organs (bowels, bidncys, blaildfx, InngK,) may inibtcn 
abortion. Profuse diarrhea, whether occurring from the reckless uko 
of purgatives, the consumption of irritanis Iu tbe fond, or a simple in- 
digestion ia an effeeli\'o cause. Xo less so is acute indigestion witk

evolution of gas in llio intostiiies (blunting). Tlie iircKnuw of Hlonc la 
tlio kiilnHy.K, uivtur^, bladder, or nretlira may induce eo nitieii sytojia- 
tlietiu diBonter in tlio u omh as tii imluru tvlturtiiiii. In cscoiitiutial i:usc8 
Trlicruia luarcB como iu licat duriug gestation service by tlio stallion 
may c;iHso abortion. Blowg or pressure ou tlie aluIoineD, nipid driviaf 
or riding of the iireguaut mare, esi>*rially if she is soft and out of c^q- 
ditiou from idliincas; tbo brutal uso of tkeepur ur wlilp, and thojoMing' 
und.stniiuirigof travel by rail or boat are prolific causes. Bleedi)i|rtli« 
prt'guaut maw, a painful surgical oporation, and the tbrowjug and t-on- 
Btraiat resorted to for an operation are otlier cause*. Traveliuji on 
beavy, muddy roads, slli>s and falls on ice, and jumpjug uiuitl bo lidded. 
Tlie stimulatioii of the abtlominal organs by a full drink of iced water 
may procipitato a miscarriage, us may etposare to a cold rain-siorm or 
a very cold iiigbt after a warm daj'. Irritant, poisons that act on the 
urinary or generative organs, sncb as Spanish fliea, me, savin, tansy, 
cotton-root bark, crpot of ryo or otbcr grasses, tlio smut of maize aiid 
otbcr grain, and varicuis fungi in musty fodder uro additional caUMS. 
Frosted food, Indigestible fooil, and above all greeu succnlent vegetable* 
iuafrozenwtat^bave proved effective factors, and filthy, stagnant water 
is dangerous. Low condition iu the diuii and plethora have in opposite 
v.nys caused abortion, and hot relaxing stables and lack of eserciao 
strongly condnce to it. The exhaustion of the sire liy too frequent 'serv- 
icf, entailing debility of the oflsjjriug and disease of the fu-tus or of 
its envelopes, must be recognized as a further cause. 

The symptoms varj* mainly according as the abortion is early or late 
in pregnancy. In the first month or two of pregnancy the mare may 
misfiirry without observable syiiiptoms, and the fiwit only appcirs by 
her coming in licat. If more closely observed a small clot of bluod may 
be foaud behind her, in which a careful search roveaU the ruditueuta 
of the foal. If the occurrence is soniewhat later in gestation there will 
be Bume general disturbance, iuappeleuce^ neighing, and straining, and 
the email body of the fietus is cvpelled, enveloped in its membraoee. 
Abortions during tbe later stages of pregnancy are attended with 
greater roastltutionnl disturbiiuce, and tbe process resenibliut iiormiil 
parturition, wllb the agfrravation that more eRVjrt and straining is req- 
uisite to force the foBtus through the oomparatively nudJlatable mouth 
of the womb. Tliere is the swelling of tbe vulra, with mucus or even 
bloody discharge; the abdomen droops, the fianks fall in, the udder fills, 
the mare looks at her Hanks, paws with the fore feet and kicks with 
the hind, switches tbe tail, moves around uneasily, lies down and rises, 
strains, and, as in nntumi foaling, expels first mncus aud blood, then 
the waterM, and Qnally tbe fuitiis. This may ocumpy an hour or two, or 
ft may bo prolonged for a day or more, the symptoms subsiding for a 
time, only to reappear with renewed energy. If thei-e is malpri'st-nta- 
tiouof the fuctus it will binder progress until rectified, as m ditlicult

entire abscuco of inoremeut, arc saggestive symptoms aiid should be 
duly coauteracted. 

The changes in the vulva and nddcr, vrith a soilcil and bloody condi- 
tion ofthe tail, ntay sug^^est uu abortion ah'eady accomplished, atid the 
examination with tlit? band in the vagina may detect the month of Itio 
vombsoft and dilatablo, and the interior of the organ sUtfbtly filled with 
n bloody liqnid. 

Trealmmt should be preventive if possible, and wonld embrace the 
avoidaaoe of all canscs mentioned, and particnliirly of suchns muy seeui 
to be particntarly operative in the particular case. Where abortions 
have already occurred in a stud, the especial cause, iu the matter of food, 
water, exposure to injiiriw, overivorl;, lack of exercise, etc., may often 
be idcntiHul and removed. A most important point is to avoid all 
MOMS of oouBtipation, diarrhea^ Iitdigestion, bloating, violent purga- 
tives, diuretics or other potent medictucS] painful operations, and slip- 
pery roads, unless well frasttHt. 

When abortion is imminent the mare should bo placed alone lo a 
roomy,dark,qnietKtall, and ha%'e the straining checked by some sedative. 
Lnudnonm is usually at hnnd and may be given in doses of 1 or ^ ounces, 
according to size, and relocated after two or three botirs, and even dally 
if neces!t»ry. Chloroform orchomthydrate,3drnm8, may 1>csnbstituteil 
if more convenient. These should be given in a pint or quurt of water, 
toavoid barning the mouth and throat. Or viburnum pranifolium, 1 
ounce, may be given and re])eatc<l if ucooasary to prevent atrainlug. 

When all measures fail and miscarriage proceeds, nil tbatcanhedone 
it to ii-tsist in the removal of thufrftnsitnd il.t memlinHies, as in ordinary 
parturition. As in the case of retention of the fa-Cus, it may bo neces- 
sary after delivery to employ antiseptic it^ectiona into the womb to 
counteract putrid fermoiitAtion. Tliis, however, is less requisite in the 
maruthan in the con-, in which the pnn-ak-nt c<intngiou8 alnirlion naisfe 
be counteracted by the persistent local use of antiseptics. After abor- 
acarefnl hygiene is demanded, cffpccially in the matter of pure nip 
CAsily digestible fooil. The mare Klumld not be Kt>rved again for a 
month or longer, and in no case until after all drscbarge from the vulva 
bMoeaaed.

Axintof the boofs and knees and tbo forcbcad dircctctl upwanl toward

the foal passes with much greater ease than if it were plac«d wiib its

TWISTINO OP THE NKCK OP THE WOSID. 

Tbi& eouditloD h very uncommoa in tbe marc, tbougli oceasionally 
Bceti in tlic coif, owing to the greater Inxity of tlio broad ligamentsof 
tlio tronib in that animal. It consiaU in a revolution of tbo womb on 
itH own Axi&^ fto tbat its right or left side will he tnriicd npward (qaarltf 
r<>Tol[ition),or tbo lower snrfaco may bo torned upward and tbo upper 
jturfacc downward (biilf revobition). The effect Is to tbrow tbe narrow 
Dcek of tlie womb into a series of spiral folds, turning in (bv dinrction 
in wbk'b (he womb ham revolved, dosing the lieek and rendering dis- 
tention nnd dilatation impossible. 

The period and pains of parturition arrive, but- in spite of continn«d 
efforts no progress is made, neither water-bags nor liquids appeariug. 
The oiled band iutrodaeM into tbcclosed neck of the womb will readily 
detect tbo spiral direction of the folds on its inner surface. 

Tlie method of relief wliicb I have sucwssfully adojited iu the cow may 
be equally happy in tbe mare. Tbe dam is placed (with Ler bead op 
hill) on ber right side if tbo upper folds of tbo spiral turn toward the 
right, and on her left Bide if they turn toward the left ; nnd the oiled 
band is introduced through tbo ucck of tbo womb and a limb or other 
piirt of the bodj- of tho ftfituB is seized and pressed against the wall of 
the womb, while two or three assistants turn tho nnimnl over her liaelc 
toward the other kUIo. Tbe object is to keep tbe womb statiouary while 
the auimat is rolling. If success attends tbe effort, tbe constrictioa 
around the arm is suddenly relaxed, the spiral folda aru effaced, and 
tbo water-bags and fcetas press forward into the passage. If the Srat 
attempt does not succeed it may bo reiieated again and again until sue- 
c*'ss cniwMKs the effort. Among my occasional causes of failure bare 
been tbe prior death and decomposition of tho foetus, with the extrica- 
tion of gas and overdititention of the womb, and the superveucioti of 
inflammation and inflammatory esudatloii around the neck of the womb, 
which hinders untwisting. Tho firstof these conditionsoccnrsearly iu J 
tbe horse from tho detachment of tbe ftetal uicinbrancs from tbe wall ^ 
of the womb, and as the mare ia more subject to fatal peritonitis than 
tho cow, it may l>o concluded tbat Iwth these sonreea of failure ara 
more probable in tbe cqnJno subject. 

When the case is intractable, though the baud may be Cituily tn- 
trodaccd, tbo instrameut sbowD in Plato VUI, Fig. 7, may be used.

The caueet of monstrositios appear to be very varied. Somu mou- 
Btrositles, like extra digits, ab^uco of horns or tailu, etc. ran iu fami-

of part«, the extra jmrt or tnetnber has munift'sUy developed from the 
aauiiiovutn and nutrient center with the uormal mcuibor to wtiicb it 
remainK udhereut, jutil as a new tail will grow out iu a newt n-hen the 
the lonner bus been cut off. In thcenrly embryo, witb its great powers 
of dcvulopuifut, this factor can operate to far greater jKirptist^ than iu 
tbe adult animal. Its iotlueuoe is seen in the fact itoiuleil out by &t 
Bflairc that such redundant parts aro nearly always connected with the 
corresponding portions iu th^i normal foetns. Thus supcrflnnns legs or 
digits are iittached to the normal ones, doable heads or tails are oou- 
nected to a commou ueck or rump, and double bodies aro attached to 
each other by corrcspoudiug points, nuvol to navel, breast to breast^ 
back to back. All this snggtwts the development of extra parte from 
the same primary layer of the impregnated and developing ovum. The 
cfl'eot of disturbing ooudilioos in giving snob wrong directions to tbo 
developmental forces is well shown in the expcriuicnts of St Uilaire 
and Vnletitine in varnishing, xhnking, anil otherwise breaking up the 
natural (umn pel ions in eggs, aud thereby determining the formation of 
motistroaities at wilt. So, in the mammal, blows and other injuries 
that detach the fu-tal int'iiibraiie!* from the w.-ills of the womb or that 
modii^ their circnlatiou by iniliicing tuUammalion are at times followed 
by the development of a monster. The excitement^ mental and phys- 
ical, attendant on fright occasionally acts in a sliaUar way, aoLine prob- 
ably through the same cbauuela.

If panitritiou continues to make progress the displaced foot may

aod parturition is easy. 

When both bead and ncuk aiu lient downward it may be impossible

I f tbo labor bus been long in progress and tbo foetu^i is jammed into

Tliis is rare, yet not unknown, the foal beiug bent upon itself with 
the buck, recDgri)zul>lo by its Kharp row of spines, preseiileil at the en- 
trance of the pelvis, and the head nud all four feet turned back iuto the 
womb. {Plate XI, Fig. 1.) The body of the f<ems may be extended 
across the opening transversely so that the head corresponds to one side 
(right or left), or it may bo vertical with the head above or below. 

In any such position the object should bo to pnsh the body of the 
foetus forward and upward or to one side, as may best promise to bring 
lip the fore or hind extremities, and bring the latter into tho passage so 
as to coustitule a normal anterior or posterior presentation. Thia tmu- 
iog of the foetna may be favored by a given position of the mother, by 
the free nse of oil or lard on tho snrface of tho fcDtus, and by th? nso of 
a proueller.

extra hind Iiu)t)s, or whoa the hind limbs are bent forwanl at hock or 
hip joint Iu the former condition tbe procedure resoroblos that for 
removal of u fore-limb, but requires more anatomical knowle<lge. Bar- 
ing noosetl llio pastern, a circular incision is made through tbe skin 
around the fctlook, and a longitudinal one from that up to the groin, 
and tbo skin is dissected from the limb as high ujt as can be reacbt:<t, 
over tbe croup if possible. Then cut tbnnigh the nuiKcles arouuil the 
hip joint, aud, if jHissible, the two iulerarUcnlar ligaments of the joiut

Eeriously interfere wilb the return of tlio mass. In returning tbe vooib 
tbe standing ia preferable to the rccnmb(>nt position, uh the abtlomen 
is more pendant and there is less obstruction to tlic return. It way, 
hon-crcr, bo necessary to put hobbles ou the bind limbs to prevent tbe 
Qiare from Iciclcing. A clean sheet Bbotilil be held beneatb tbe womb

beginning at its most dependent part (tbo extremity of tlic bom). This 
serves two good endti. It ^qtieezeei out into Ibe general cli*culatioD tbe 
enormous mass of blood which engorged and enlarged tbe organ, and 
it fnmtghcs a strong protective covering for tbo now delieato friable 
organ, through which it may bo safely manipulated williont danger of 
lacuralioii. Tbe next step may be tlie pressure on tbe general mass 
while those portions next the vulva are gradually pushed in witb the 
bauds; or tbe extreme lowest point (the end of tbo boru) may be Inrnud 
within ilself and pushed forward iuto tbe vagina by the closed fist, the 
relani being assisled by mauqmladous by the other hand, and even by 
thoso of assistants. By either mode the nianipnlutions may bo made 
witli almost perfect safety so loug as the organ is closely wrapped io 
the bandnge. Once a portion has been introduced into the vagina tbe 
rest will usually follow witb increasing ease, and the o]>eraUon should 
bo completed witb tbo band and arm extruded tbe full length within

DISE.-VSES OF THE NERVOUS SYSTEM. 



By U. R. TRUMBOWER, V. 3. 



TIXB ASATOUT AND mTSIOLOGY OP TUB CRAi:! AKD KSSTOVS 

BVSTE.V. 

TIio nerrons system may bo roganled aa consisting of two seta of 
Wjpltia, pcripbornl ami central, the function of one being to Mtablish a 
eommanlcatton between the centers and tbo different pnrts of the body, 
and that of tlio other to gcuersto nervous force. Tho vhole tuay be 
arranged ander taodirisions: First. The cercbro^gpinal or nervous sys- 
tem of aniraal life. Se^iond. The ai/mpaihetic, giin;:lionif, or nervona 
eystcrn of organic life. Enchispossessedof itsowncentral and periph- 
eral orgnns. 

In the Jirttf the center Is made op of two portions, one large and 
cxiKiuded- the brain — placed iu tho cniiiial cavity; tli« ntticr elon- 
gated—spinal cord — ooDtiuuous with tlie hmin, and lodged in the canal 
of the vertebral eolaiun. Tho peripheral portion of this system consiata 
of till) crnrbi-o-spiriul nerves, which leave the axis in synimetrical pairs, 
and are distributed to the skin, the voluntary moscies, and tlio organa 
of common and spinal srosatioD. 

In the second, the central organ consists of a chain of ganglia con- 
nected by nvrvo conLs, which extends fnjm tlie head to the ruuip on 
each side of the spiuo. Tlionervesof this system are distributed to the 
inrolontary muscles, mucoas membrane, viscera, and blood- vossela. 

Tho two systems have free intercommuutcatiou, ganglia being at the 
Junctions. 

Ttro substances, distingnlshablo by their color, enter Into the forma- 
tiou of nervous matter, viz, tlie white or uednllary, and the gray or 
oorlical substance. Both are Bofti fragile, and easily injured, in ooa- 
w^inenceof whirh the principal nervous centers are always well pro- 
tected by bony coverings. The ucr\'ou3 substances present two dia* 
tinct forms — neree fibers and nerva ce\l». Aa aggregation of nervo cells 
coQstitntes n non'e ganglion. 

The nerve Hlwra represent a conducting apparatus, and (ten'e to

for tlie sensory, peroeiJtive, trophic, onfl secretory lunctioDS. A ucrvo 
consists of a bundle of tubular liWrs, held together by a dense areolar 
tissue, and inclosed io a membrnnoas shcatU— tho ncnrilemraa. Nerve 
Qburs possuiis uo clusticity, but are very stroug. Divided nerreti do not 
retract. 

l^vrrea nre thrown into a state of excitement vfacn etitnatated, and. 
ore, therefore, said to possess ejccitablc or irritable propertita. The 
HtJtniili tii:i}' bo itpptitd to, or may act npon any part of the iierre. 
Ken'es maybe patalyzcd by continuous pressure being applied. "When 
the nerves divide into brandies, tbero is never any splittitig up of tbeir 
ultitiiato fibers, nor yet ia there ever any coalcsciug of them; they 
retain their individuality from their eourcd to their termination. 

Nerves vrhich convey impressloas to the centers are termed sm»ory 
or centripetal^ aiitl ttioso whlcli tranntnit .lUmulaa from the centers to 
organs of motion are termed motor or cttttri/u^L 

The Ainctton of the nervous system mayt therefore, be defined in the 
simplest terms, as follows: /( ia intmitftt io astoriatt ike differtnt part$ 
of the Ihm};/ in nitch <i mattner that KfimKltui applied to one organ may e» 
cite or deprei* the activity of another. 

The brnJn is that portion of the cerebrospinal axis vithin the cro- 
ninm, 'nliieh may \n^ divtdi^d intn four parts — the mednUA ohlnjiffata, tbe 
cerebrtlum, thojion* Vitrolii, and thocerelirumj and It is covered by tbre« 
membranes called the meninges. The first of these membranes, the 
dura mater^ tfl a thick, white, fibrous membrane which lines the cavity 
of the enintntn, forming the internal perioslenm of the bones; it is cod- 
tinuouswitb tbe spinal cord to tbecxtreiuily of the canal. The second, 
the arachvoitt, is a delicate 6«roua membrane, and loosely envelops the 
brniu and spinal cord; it forma two layers, Ipavinff between tliem the 
arnehnnid Kpace Tvhich eontains the CFrpbn>'<ipinn], tlittd, the nse of 
which Is to protect the spinal cord and brain from pressure. The tbtril, 
tbe pin mater, is closely adherent to the entire sorfncc of tbe brain, hot 
is miirh thinner and more va-scnlar ttian when it reaches tho Sfiinal cord 
whiph it also envelops, and is eontinned to form tbe sheaths of tta4 
spinal nerves. 

The medulla obhngnta is llie prolongation of the spinal cord, extend- 
iug to the pons Varolii. This portion of tlie brain is ver>- tarfce tn tho 
horse; it Is pyramidal in Bhai>e, the narrowest part joining the cord. 

Thesis Varolii {s the transverse projection on the base of thebniin, 
between the me<lnll» oblongata and the jwdnncles of the cerebrum. 

Tho cerebellum is lodged in thn [wsterior part of the cranial CBrity. 
Immediately above the medulla oblongata; it is globular or elliptic*! in 
shape, tho tmnsvprse diiimeter beiiiji fjivatest. Tbe body of the cere-

Sj^mptoms. — Acute cnci^pbalitis may be uslicred in by au increased 
seoKibility to uoiscs, vrith mora or leas ucrvou.s excitability, contraction 
of tbe pupil of tlic eye^ aud a quick, bard paUe. Id very acute attacks 
these symptoms, however, are iiot always uoted. This condilioo will 
soon be folloired by mnscular tnitcbiDg8,coiivnUive or spn^imoilic move-

Where tlio membrniies ara greatly implicated courulsions and delirium 
with violence may be expected, bat wlicre tbe brain substances in prin- 
cipally alTi-ct«d stupor and couiu will be tlic prouiiucnt symptoua. la 
tlio former condition tbe pulne will be (juick aud hard, in the Initcr soft

teroua brcathuif;. Ttie symptoms may follow oiio auotbcr iu rapid suc- 
cession, and (be disease approach afat:il tcrmiuationio Icastban twelve 
hours. In subacute attacks tlie symptoms are bettor de&ue<t, aud tbo 
animal seldom dies bofoio tbo third day. Within three or four day« 
gradual improvement may become manifest, or ccrKbral nofleaing with 
partial paralysis may occur. In all cases of cncepbalitis there is a 
marked rise iu temperature from liio very onset of tbo disease, with a 
tendency to increase until the most alnrming symptoms develop, snc- 
ceedeil by a decrease wben coma becomes m.inifested. The violence 
aud character of tbo symptoms greatly depend upon the extent and 
location of the structures involved. Thus, in some cases wo may Qud 
marlicd paralysis of certain muscles, wblle in otUers wo may bavo spas- 
modic rigidity of mu-scles in a certain region. Very rarely tbe animal 
becomes extremely violent early in the attack, aud by rearing up, strib- 
iuR with tbe fore feet, or falliug over, may do himself great injury. 
Usually, however, tbo animal maintains tbo standing position, propping 
himself iigaiiiKt tlic mang(>r or wall until be falls fmni iunbility of mus- 
cular couLrol or unconsciousness. Occasionally he may go through a

Contrary to acute enccpbalitts, this form is not cbaract«rtzc<l iu it» iui- 
Ual stages by excitability, quick and himt pulse, and btgh fuvcr. Tlie 
animal appears at flPHt stupid ; eatii slowly; die pupil of the eya does 
not re:ipoud to light quickly ; tlie animal often throws np his head or 
shakes it as if eiifforing Auddou twinges of pain. He is slow aud slug- 
gish in his movements, or tbero may bo partial paralyKis of one limb, 
one aide of the face, nect, or body. These nynipioiim, with uimib varia- 
tional may be prcscut for several days and then subside, or the disease 
may pass into the acute stage and tcrminat-e fatally. Chronic encepha- 
litis may affect an oaliual for tea days or two ^vecks without much var- 
iation Hi the symptoms before the crisis Is reached. If improvement 
oommeaces the 8ymi>toms usually disappear in the reverse order Id 
Thlclt they developed with the exception of the paralytic eflfects, whioh 
remain intractibloor permanent. Paralysis of certain sots of muscles 
is a very common result of chronic, subauitio, anil iicuto enceplmlitis,

tlie pupils of Uie eyes contracted, aud the muscles of the body quivvr>

OKREBHITIS— 1NFLA3IMATIOS OP THE n&AIN SUBSTANCE. ^ 

CdfrM. — The caases giviug rise to this disease ai-o very numerous. 
Among them may be mentioned all those named heretofore as causing 
enceplialitis and meningitis, cystic and cjitrarcous tumors, tbrombl, 
ura'iiiic poiMtiiiug, nictiustatic ubsu-s.scs, septic infccLiou, etc. 

Sj/tuptoms. — Cerebritis, when an accompanied by other disease, is sel- 
dom recognized as such dnring lire. It is aln-aj-s localized in extent, 
and the symptoms manifested depend ujion the location of the organic 
vhanjio for tlicir obnracter. The symptoms, therefore, are as varied as 
the caosi'S; tUcy are usually of slow development and persistent. Ver- 
tigo or giddiness may bo regarded as a constant symptom. The ani- 
mal may stop on tbe road, sliaki! Iiih head, or stagger, apjiarently un* 
decided in what direction to go. There may be contraction of the pu- 
pib, cramp of the muscles on the side of the neck or face, pulse emalt ' 
and hard and variable in rre4{ueiioy, oftt'n, however, slower than normal. 
The temperature is slightly increased, the respiratious may be slow and 
dce|i» the appetite capricious, bowels constipated; rapid emaciation ia>f 
a common symptom. iSnch conditions may be apparent for a week or^ 
la-o weeks; then the horse may become comatose. The pupils dihite, 
thu pulse becomes nitermitUng, swallowing difllcult, the muscles wliieii 
were previously rigid become rela-xed and paralyzeil, and tbe urine may 
either be retained or be discharged iuvolnntarily. In this way tbe ani- 
mal may survive aonlher week and then die in a paralyred nnd nncon- 
scions state. Kot iufreqiteutly, however, few of those symploiu-i are _ 
manifested, for in some eases the paralysis is sudden fhim exten.sive ■ 
lesions of tbe brain, and tbe animal may die witJiin twenty-four hours.

TreatiBent. — Id all nciito nttacks of liiflammation iiirolving thn mem- 
branca or cerelinil masses, it is tlie pressure from tbo distended and 
engorged bloodvessels, and the rapid accuoiulatimi of inflummatory 
procIuctB, that cddangors the life of tlio aoimal in even the very early 
stage of tho disease. Tlio earlier tlio treatment is eommoncod to lessen 
the danger of fatal pressuro from the engorged blood- vessels, the less 
amooDtofinflatniuiktory products nod effusion we havo to contend vHh 
later OD, The leading object then to bo ncooniplished in the treatincat 
of tlie first stages of encephalitis, meningitis, or cerebritis is to relieve 
the engorgement of tho b]ood>vcKftets before a dangerous degree of cffa- 
sioD or exndation has taken place, and thereby le&seu the irritation or 
excitability of tlic afft^ctcd fltnictnres. If wo fally succeed in this stage 
in the accoiiiplishmeiit of this object, we certainly prevent a secoud 
stage of the disease, aud it will only be required to continue a treat- 
ment which will tend to lessen irritability to prevent a second engorge- 
uent from takiug place. Batif theatteuipttorcliorcthocngorgcment 
la tho first stage has biien only partially successful, and the second 
stage with its inflnoimatory products and exudations, whether serous 
or pla.stic, has set in, then the m:un objecta in further tn-atnient are to 
keep up the strength of tho ariiiual and bastca tlic absorption of tho 
exudative produutK as tnucb as possible. To obUlu Ibese results, whoa 
the animal is found in tho initial stage of tho disease, where there ia 
nnnatural excitability or stupor with iiicre:ise of temperature and qiiick- 
eacd puisc, wo must roly uikiu the safest and quickest acting remedy 
at hand, which Is copious bleeding fh>m tho jugular vein. Especially 
in acute meningitiFt, bleeding is imperatively demanded. Tho linger 
should be kept od tho pulme, aud the blood allowed to (low until thero 
is a marked fluttering or softening of the pnlse. As aoou as tho animal 
recovers eomcwhat from tho shock of tbo bleeding, the followiog medi- 
eino should bo made into a ball or dissolved in a pint of warm water, 
and be given at one dose : Barba<loes aloes, 7 drams ; calomel, 2 drams ; 
powdered ginger, 1 dram; tincture of aconite, 20 drops. 

Tho animal should be plncctl iu a cool, dark place, as free from noiso 
as pu>t.4ible, and cloths wrung out of hot water placed on bis hetid. 
These should bo renewed frequeutly for at least twelve hours. When 
the animal becomes thirsty half an ounce of saltpeter may be dissolved 
in his dritikiug water ererj' six hours. Injections of wAnn water into 
th» rectum may faeilitcte thci action of the purgative. Norwood's tincc- 
nre of veratrum virtde, in 20 drop doses, shoald bo given every boor, 
and one dram of solid extract of belladonna every four hours, until 
tho symptoms become mo^liAvMl and tbo pulse regntar aud full. 

f this treatment falls to give relief the disease will pass into tho nd< 
d stages, or if the animal has been neglected in the early stagM

ergotiii, ia 5 gniin doses, dissotvcd in a dram of water, every sis 
bours. Ttic liaibs timy bo poulticed abo^'e the fetlocks nllh mustard. 
Cold n-ater or Ice-bngs should uow take the place of the hot-water elotha 
on tbo Lead. Warm bliiukutiiig^, to iiromotc i>crspiratiuu, is to bo ob> 
ecrred in all cases in which there is uo excessive perspiraUon. 

If the disease becomes chrouic — cncopbalitU or meoincltiii — we must 
placo our reliance npon alteratiros and tcnics, with sneh intridtMital 
treatment an special tiymptotns may demand. Iodide of potaMHtuni in 
S-dram doses should bo given twico a day, aad 1 dram of catomol 
o&ce a day, to iadacc absorption of uffuaious or thickened mcmbrUDCs. 
ToDiCS, iu the form of iodide of iron in dram doxes, to which is added 
2 drams of powdered hydraslis, may also be given every six or eight 
tionrs, as soon as the active fever has abated. In all cases, after the 
disappearance of tbo acato symptoms, blisters (cantbaridesoiotiueut) 
shnuUl bo applied behind the poll. When paralytic effects remain nftc 
the disappearance of all other symptoms, snlphate of strychnia iu 2-grain' 
doses, in combination with tho other tonics, may be ^vcu twice a day, 
and be cotitiauetl uutil it pi-odaces muscnlnr twitching. Iu some cases 
of paralysis, as of the lips or throat, bcucQC may bo derived from the 
moderate nso of tlio electric battery. Munyof the recoveries wilt, bow- 
ever, under the most active and curly ta'utmeut, be but partial, and ia 
aU cases the animals become predisposed to subsequent attacks. A 
long period of time should bo allowed to pass boforo tho naimal is ox- 
oiispil to severe work or great heat. When tho disease depends npoa 
^necLauical itijuries they have to be treated and all causes of irritatioa 
to tbo brain removed. If it is duo to stable iitinsma, urmmic ])otsoD- 
ing, pyieraia, inftitenza, rheumatism, toxic agents, etc., they should 
receive prompt attention for their txumoval or mitigation.

COSQESTION OP TDE BBAra— MKOEIMS. 



Congestion of the brain consists In an nocnmulatfon of blood in the 
Tcssels, abw called hT|H>ra;mia, or engorgement. It may bo active or 
passive — active when there is an undue determination of blood or 
diminished arterial r<-fiistance, and passive when It accuninlute^ In the 
Tes-wls of thR brain, owing to some obstacle to its return by the veins. 

CauMe9.-~-Aeiivo cerebral congestion may bo dno to hypertrophy of 
tlie left ventricle of the heart, excessive exertion, the influence of ex- 
treme heat, eiulden and great excitement, artificial Btimutanls, etc.

Ss'uptoms. — Ci)iigt-.stioii or the brain Is u»ually sudden la tia tuaui- V 
fcstatioD and of short duration. The animal may stop very suddenly 
and sbnko his head or sttod quietly braced ou his legs, then stagger, 
niiiko a plunge, and fall. The eyes are staring, brca.lhiiig hurried and 
stertorous, and the uoslriis widely dilated. This may be follovcd by 
oouia, violent conx'uUiTd movements, and death. Generally, hovrever, 
the animal gains relief in a short time, but ho may remain weak aud 
giddy fur several days. If it is due to orgnuio change of the heart or 
to disease of the blood-vessels iu tUo brain, thou the symptoms may be 
of slow development manifested by drovainess, dimness er imperfect 
vision, difilcuity in voluntary movements, diminished sensibility of the 
skin, loss of conKcioiisuess, delirium, and tieath. In milder eusfs eO'a- 
sion may take p1ac« in the arachnoid spaces and ventricles of the brain 
foIlo\ve<1 by pundyiiis and other com jdj cations. 

Vtilhologg. — In congestion of the brain the cerebral vessels arc loaded 
vitb blooil, and the venous sinuses distended to an extreme degTce, 
aud the pressure exerted npon the braiu couslitutes actual comprea- 
sion, giving rise to the symptoms just mentioned. On poat mortem ex- 
nminatioiis this engorgement is found nuivcrsul thronghout the brain 
aud its membranes, vrhich serves to diHtinguish it from iuflammations 
of these structures, in wliich the engorgements are confined more or 
less to circums4:ril>ed t>ortions. A pr»Iong<-cl rorigt-stiau may, ho»-(>ver, 
lead to active inflammation, and in that case we irill And serous aud 
plastic exudations in the cavities of the bratn. In addition to the in- 
tensely engorgwl condition of the vessels we find the gray matter of 
the brain redder iu color than natural. In cases w here several attacks i 
have occurred the bloodresscis are ofteu found permnncutly dilated. ■ 

Trtatoieni. — Prompt removal of all mechanical olMdrucUons to the 
circulation. If it is due to venous obstruction by too light a collar, tbe 
loosening of the collar will give iuimedtatc relief. If due to tumors or 
abscesses, a snrgical operation becomes necessary to afford relief. To 
Tcvive the animal if he become partially or totally uuconsdous t-fdd 
water should be dashed on the head, and if Uiis does not aflTord ready 
relief recourse must be bad to bleeding to lessen arterial tension. Tinct- 
ure of vcratrurii viride or of aconite root may be given in twenty -drt^) 
doses every hour until conscionsness relunis. If the limbs ore cold

ApopLKXT — cehehrai- nKMonnnAnn. 

Apoplexy is oCteu confounded with cerebral congestion, bat trno 
apoplexy alnays consUts in rupture of cerebral blood-vessela, with 
blood extravasation and furuiiilioii of bluod clot. 

Cautet. — Tiro causes are involved In the production of apoplexy, tha 
predispoaiiif} and tho cxciling cause, Tho predisposing cauee is degeu- 
cratiou or diaenso which weakens tho blood-vessel, the exciting cause 
is any one which tends to induce cerebral congestion. 

Sjfmptoms. — Apoplexy is cbaracterised by n sudden loss ofsensatiou 
and motion, profound Crunin, and steitorons and diltlctilt breathing. The 
actiou of tho heart is ItlMe disturbed at first, but soon becomes slower) 
then quicker and feeblur, and after a little time censes. If the rupture 
is one of a smalt artery and tho extrava»atton limited, sudden paraly- 
sis of somo part of the boily is the rcsnlt The extent and location of 
the paralysis depend upon the location within tho brain which is 
fniictionnlly deranged by the pressure of the extra vasatcd blood ; hence 
these conditions are very variable. 

In the absence of uny premonitory syniptoms or an inorensc of teni> 
peratare in the early stage of the attnck wo may be reasonably certain 
in making the distinction between this disease and congestion of tlift 
brain or sunstroke. 

Pathologg, — In apoplexy wc are generally able to find an atheromatous 
condition of the cerebral vessels with weakening aud degeueniUou of 
their walls. When a largo artery has been ruptured it is usually fol- 
lowed by immediate death, and large rents may be found in tho cere- 
brum, with great destruction of brain tissne. induced by tho forcible

6PANM OF TUB THtOK, OE GEAMP OF A IIIMl) LIMB. 

This Is frequently witoeasod in borses that stand oa Hlopiug plauk 
floors — generally in cold weather — or it may come «in soon after severe 
cxcrct'ie. It is prohably due to an irritaiion of the nerves of the thigh. 
In crHmpHof the hiud leg the limb becuuies perfectly rigid, and at- 
tempts to flex the leg are iiu successful ; the animal stands on the affected 
limb, Init is unable to niovn it; it i» unnaturally <xild ; it does not, bow- 
ever, appear to cause much suffering uulcss attompts aru niudo to 
change iKJHtliou. Thiscraiuii may be of short duration — a few minutes — 
or it may persist for several days. Thisconditiou is often taken foradis- 
lucftlioDof the nUUc-Joint. In tho latter tho foot Is extended backward, 
«Qd the horse is uuable to advance it, but drags the limb after him. An 
exaaiinalion of the Joiut also reveals a chango in form. Spa»m» may 
aff»-ct the uye-llds, by closuro or by retRiction. Spasm of tho steruo- 
mHxilluriM muitclc has biwn witiiussi^il, and tlio animal was uimblo tn 
i-loa« thejaws until the muscle became leluxed. 

Tr€atment. — An anodyne Huiment', composed of chloroform 1 part 
Mid soap liniment 4 partK, applied to crauiiwd musclox will nsuidly 
cauao rtrlaxation. This may be used where single exturuul muscles arc 
affected. In spanm of tho glottis inhalation of Bnlphunc ether will 
ipve quick relief. In spiisiu of tho diaphragm, rust and tho adminis- 
iratiou of half an ounc« of chlomform in :t ounces of whixky, with a 
pint of water ailded, will generally suffice to bring relief, or if this fails 
givu & grains of sulphatu of morphia by hyjiodcrmtc iiijccliou. If 
npasiiis result from organic disease of the nen'ous aystem, the latter 
should receive such treatiiioiil as it» character deniiirulit. In cramp of 
iho leg compidsorj' moveiiifiit usually causes relaxation vcryqnickly; 
tliontfore, tho animal Hhould 1h: led out of tlio etablo and be forceil to run 
or trot. Saddeo cervous excitement, caused by a crack of tho whip or 
•mart blow, will oftea bring about immediate relief. Should this fail, 
th« anodyne liuimfiit may be umnl along the insido of the thigh, and 
chloroform, other, or laudanum giveu interually. An ounce uf tho 
dUoraJ hydrate viU ctittaiul^' relieve the spasto whou givcu iutcrually,

PAEALTSIS— PALST. 

Paral.TslB is a weakness or cessatiou of the muscular contraction, by 
diniiuntioii of losa of tlie condncting power or ntimulation of the mo.or 
ULM'ves. I'aralytic aflVctioutf are of two kinds, tLe perl'ect and the im- 
IM-rfoet. The former includes tlioso in wbicli both motion and eenel- 
bilily aro an<>cted ; thn latter those in which only one or tbe other is 
lost or dimiui.-«lied. Paralysis may he general or partial. The latter is 
divided into bemiplegia and paraplegia. When only a small iMirttou 
of tbo body is affected, as the face, a limb, tbo tail, it is designated by 
llie term loeul imnilysis. When (he irritJition ^xtendii from the pe- 
riphery to [Im wnter it is ttrmed refli-x paralysis. 

Causes. — ^They are very varied. Most of the acntc afleetions of tbe 
brain and spinal cord may lead to paralysis. Injuries, tumors, disease 
of tbe blood veHHelK of the brain, i>te., all h:ivt< a tetiiteney to prodnoe 
susjiensiou of the couduutitig motive power to tbe muscular Ktraotures. 
rn'a»Hn5 upon, or the serering of, a nerve (;aufie» a paralysia of the 
parts to wliicb sucli a nerve is dlstribiitiil. Apoplexy umy be termed 
a general paraly»iH, and in uon-fatal attacks in a frequent cause of tbe 
various forms of palsy. 

GENERAL PABALY8I3. 

This can not lake place without producing immediate death. Tbe 
term Is, however, usually applietl to itaralyMH of tbe four extremities, 
irbetber any other portions of Mie body are involved or uot. This form 
of palsy is due to couipi^-ssiou of tbe brain by cougcetiou of its vessela, 
large clot formation in apoplexy, concussion or Rhook,or.any disease in 
which tbe whole brain structure is luvolved in fuucUonal disturbauoe. 

nEMIPLEOlA— PADALYSia OK OKE SIDE OR HALF OP THE BODY. 



Hemiplegia is frequently tbe result of a tumor in the lateral ventricles 
oftltc brain, softening of ouc hemisphere of the cerebrum, jireasure 
fb}m cxtravotiatvd bluod, fracture of tbe cranium, or it may be doe to 



SOI 

poiBOiis in tbe blood, or to reflpx origin. When hemiplegia is <!ae to or 
the result of a prior diseaso of tlie bratn, CKi)eetal1y of an intlamniatory 
cbarflclcr, it is selilom c-omiilctc; it may only nlYect one llmli and one 
Btd« of tue tiead, ucci£, or muscles aloii^ the Itaclt, and may jiass oS in 
a Tew days after tbe disappua ranee of all the oth«r evidences of tUe 
]triiunr,v aflfection. Tn the innjority of case^, hoxFeror, livmiplt>gta arises 
from enilKiti obHtruotiiig one or lunri' btnod-ressels of the brain, or the 
rupture of Bome vesael the wall ut which hud iK-conie weakened by 
d«gea«ration and the extravasation of blood. Senfiibility ju uio6t vaHee 
H not iiupairod, but in some there is a loss of seusibility aa well iia of 
motion. lu itomu cium'« the bluddt-r and ntctam are involved iu tbe 
panilysis. 

Synptotns. — Tu hemiplegia tbo attach may be very eadden, and tlio 
animal fall down |)owerU>HK to move one side of the body ; oue elde of 
the lipM vrilt be i^Uxed; the tuuguu m:iy hang out on one Hide of tlio 
mouth; tbe tail uurved around sidevays; an inability to awallow fooil 
or water may b« present, nod often tbe uriae dribbles away as fast as it 
coltpcts in tbe bladder. f^nHtbility of tbe iillected side may be en- 
tirely lost or only jiartial ; the li mils maybe cold, and Bomelimett un> 
natarally warm. In r;a«e« wliprein the attack is not so severe the aul- 
mul may be able to maintain tbc> elaudiuj; position, but will have i;rvab 
dllUeulty iu uiuviuj; the aOecled aide. Ju huuIi caHea the aufnial may 
recover from the disability. In tbe more severe^, where there is com- 
plete tofta uf tbo (Hiwer of movement, recovvricM are ruro. 



FABAPI^KOIA — TEAN3TBBBB PABALYBI8 OF THE HtND EXTHEMrTnca. 

Pua]ysl8 of the bind extremities is asually due to some injury, or 
iuflamnialioa affi-vting the spiniil oord. (See "Spinal Meningitis" aud 
"Myelitis.") It may also be due lo a rcflei irritntiou from disease of 
(K-ripbrrat ucrvc«, to Bpirnil Irritation or eungestion caused by blood 
poiHons, etc 

tSftHptomM, — When due to mechanical injury of the Hpinal conl, from 
a broken back or spinal bemorrhago, it is generally progre^ ve iu its char- 
acter, although it may \m nnddeu. When it i» causiil by agentn in the 
blood it may be intermittent or recurrent. 

Paraplegia is not difllcuU to leoogulze, for it Is charact«riKe4t by a 
weakness and im]M>rr<H:t control of the hind legH, aud powerless tail. 
The urine usually dribblea nwuy as it is formed and the manure is 
pa«bed out, ball by ball, without any voluntary effort, or the pa«sageq 
may cease entirely. When para)ilegia is complete, large and ill-con- 
ditioned sores soon form on the biji-<i and tliichs from chatlng and bruis-

SPINAL UBNINOLTIS — INPLJiMMATIOK OP TUB UEMBaANES EKTKLOF-

Causes. — This may bo inOuced by tbe irnCaut properties of blood- 
poi8ous,(*xliaustiuii,auil expUHure, spinal uuiicussioii, »1! forma of iujury 
to ttiit t«piim, tiiiuurs, caries of tbt^ verte-brie, rlieamatisiii, el«. 

8gmp{omn. — A obtll tnay 1x5 (bo pnxsursor, a rise in tutnperature, or a 
geueral weakuess aud sliirting of tho legs. Soon a painful, couvuUive 
twitchtugol' tlio ninsclea aeU In, followed by miiacular rigidity alon^ ibe 
npitie, in wbicih conilitioii the animal will move very stiffly aud evince 
great i>ain in turning. Bviduncea of panUyciis or paraplfjcia develop, 
retention or inconlincnct) of urine, and oftentimes sexual excitement is 
present. Tlio ]ire.s«nco of marked fever at the be^iniiiug of tho attack, 
ajtKOcii^ted with opinal Rympt4>iiiH,stionld lend as to sii.speetKpinal mea- 
ingitis or mycUtiH. These two condilionH usually appear together, or 
myelitis follows iiillaniination of tbe meninges so closely tbat it is almost 
impossible to separate tbe t^'o; practically it doe» not matter mucb, for 
tbe Irealment will be about tbe Kama in both caMeK. Spinal ueniugitia 
generally becomes chronic, ami Is tben marked priucipally by paralysis 
of tbat portion, or parts of it, posterior to the seat of tbn diH*.>iiK«. 

Vaihology. — In spinal racningitis we will Qud essentially the same €X>l»- 
ditton as in cerebral meningitis; there will be an etfaition of serum be- 
tween tbe memhranes, and often a plastic exudation firmly adherent to 
tlii'pm mufrr aurvrji to maintain a utate of paralyKiH for a lung time 
after the acnte symptoms have disappeared by compressing tbe cord. 
Finally, atrophy, softening, and even abseuss may develop wllhiu Cbo 
conl. Unlike in man, it 'm tisuatly found localized in h»rsi-N. 

Treatment, — Bu'^s filled with ice should be applied along tbe spine, to 
be followed Inter ou by strong blititers. Tiie fever sbonUl be controtleil 
as early as possible by givbig 20 drops of Norwood's tincture of vera* 
trumyiride everj boor, until the d^itireil rcHult is obtaineil. One drain 
of the fluid extract of belladonna, to control pain and vascular exoite- 
iDCDt of tbe spinal cord, may be given every live or six hours until the 
pupilx of th« eyen bfconu' [nvtty well dilaU'il. If lh«t pain '\» very in- 
lensu 5 grains of sulphate of uiorpbia should be iujected hypodermically. 
The animal must lie kept 9a free from excitement as poissible. If the 
urine ia retained iu the bladder it must be drawu off every four or »)& 
hours, fu Very ai!iite nttackK rbc diHeuKU genenilly proves fatal in a 
few days. If, however, the animal gf^ws butter some form of paraly- 
sis is apt to retii»in for a long time and tho trratment will bave to 
be directed ibcu toward a removal of the exudative products aud a

.V^m^ftiwix. — Tlie attacks may \w acnle or Hnbaniite. In an acute at- 
tack the auimul uxually dies witbiu four da.vR. Tbe Unst syuiploms 
whicb attract tbe attention of tbe owner is diHlvuity m chewing and 
sfrallowiug, au eiteuBiou of tbe bead and protrusion over the iiiuor 
part of the eye of ttie membrana nictitans or baw. An examination of 
the moQtb will rereat an inability to open tbe jaws to their foil extent, 
ami the endeavor to do so will prwlnce grnat n«mm« excitAbility aud 
iuereafiod spatam of the iunscle.s of the Jaw and neck. Tbe uiusclea of 
tlw n^ck nml along thu Kpiut* bveomo rigid ami thtt lt^g;« are moved in a 
Btiir muuuer. Tbe slight^^st uoise or disturhaoce throws the animal 
into lucreased «paF>m nf all tbn afri;<:ti^l miiKcleit. Tbe tall !« UKuallj 
elevAt6d ftod held immovable; the Iwwuls beeome eoiistiputed early ia 
tiMKttack. The teuii>erature and pulse are not uiuub changed. These 
■jTioptoins in the acnte type become rapidly aggravated until all the 
raiuelce are rigid — in a Htutuof tonic H]»a»iii — with a continuous tremor 
ruDuing through Lhem; ii cold perspiratiou breaka oat on tbe body; 
the bn>atbiMg beootnes painful from tbe Kimsm of tbe mtisclea used in 
iVMptraiion; the jaws are completely set, eyeballs retracted, lipadrawa 
fctgbily over tbe tevtb, noslrilis dilatfd, and tbe aoimal presents a pic^ 
ore of the most extreme agony until death relieves him. The pulse, 
wbich at Untt was not luueh affected, will lievoine i[uiek ami hard, or 
Rmall aud thready when the aiNWoi affects tbe muHcleg of tbe bcnrt. 
In the subacut« oases the jaws may never become entirely locked ; the 
nervoua excitability and rigidity of muscles are not ho great. There ia, 
bowe%'er, always sooie stiffnesH of tbe neek or spine manifest in turu-

bead nlmost exempt Id aotne cases, and have (tie body snd 1inil*s per- 
fectly rigid and incapable of movement without falling. 

TetanoH may pojisibly be confounded with ftpinal meaiDgitiR, but the 
oliarautef of the epasrnlocked jaw, retraction of the eyebatlti, the diffi- 
culty [d 8n'»llowiti;; due to spAKma of the iiiu!4cle8 of the phar.vux, anil, 
above all, the abseiioe of paralysis, should serve to make the distiiictiob. 

Treatment, — The animal Hhouhl Imj jdaoed in u box-atall withoab bed- 
ding, as fiirawny its possible from other horsoti. If in a eonntry district, 
thu aauiiul Khonid be put into an oulbiiildiiig or shed, where the noise of 
other animals will not reach hiui ; if the place is moderately dark it is 
all the better ; in lly time he should 1m; covereil Mi-jth a light nht'ct. The 
attendant must be very carefal and ijaict aboat him, to prevent alt un- 
necettsary excitement and Increase of KpuKra. 

A cathartic, composed of Barbadues aloes, 6 to 8 drams, with which 
may "be mixed 3 drains of the solid extract of belladonna, fthould bo 
given at once. This is best given in n ball form : if, however, the ani- 
mal is greatly (•xcited by the attempt or can not swallow, the ball may 
betlissolved in 3 ounces of olive oil and thrown on the back of the 
tongue with a syringe. If the jaws are set, or nejirly so, an attempt to 
ailuiintHltT in4;dicinu by the nioulh shotdd not he miule. In such cunea 
one qiiurier of a grain of alropia, with 5 grains of sulphate of mor|)hia, 
Hhcutilbedi!!)!oli*i>d in 1 dram of pure water and inj(H*tod under the skin. 
Tliix shonid be repeated fiiitni!iently often to keep the animal continually 
uuder its cffoct. This will iiRually mitigate the sererity of the spnsmotlie 
contraction of the affected muscles and le«sea sensibility to \>a\n. Good 
results may Ite obtained soinenraes by the injection per rectum of the 
fluid exicsct of bttlladoiina aud of cannalns indica, of each 1 dram, every 
four or SIX hours. This may be diluted with a quart of milk. When 
the animal is unable to swallow liquids, oatmeal grnci and milk should 
lie given liy injection \wt rt^i'tum to sustain thi» strenglh of thB animal. 
A padfnl of cool water should be constantly before him, place*! high 
enough for him to mnch it withoat ejiecinl effort; even if he can not 
drink, the lavmg of the mouth is refreshing. Bzoelleut Buooess fre* 
quLMitly may be obtaine^l by clothing the upj>er part of the bend, the 
neck, and greater part of the 1>ody in woolen blanketa kept aatamteil 
with very warm water. This treatment should be continued for six or 
eight hours at a time. It often relaxes the cramT>ed musolcfland gives 
theiD re^t. and the animal almost entire freedom from pain ; but it 
nliouhl lie used avery day until the acute K|>aMmH have permauenlly 
subsided in onter to Ite of any lasting benefit.

is rapidly excreted by the kidneys. If much muscular wrakness or 
paralysis is present, sulphate of iron in dram dofii-s, and strychuJa in 2- 
graia doses oiay be given twice a day. Iu all cases of sn8)HM?t«<l lead- 
poisoning all nteneits vhich have entered into the snjiply of feed or

Urffimic poisoning may affect the brain io nephritis, acute allmmina- 
ria, or when, from nuy cause, the functions of the kidneys becutue im- 
paired or snppreAoed and urea (a natural product) iM no lunger elimi- 
uated from these organs, causing it to accumulate in the system and give 
ntte to ura}mic poisoning. 

Symptoms. — TInemi« |Hii.'*oniiig is usually preceded by dropsy of the 
limbs or abdonieii ; a pi^culiar fetiil breath is often noticed ; tlien drow- 
siness, attacks of diarrhea, aud genemi debility ensue. Suddenly ex- 
treme stupor or coma develops ; the surfact' of the body becomes cold ; 
the pupils are intteusible to light ; the pnlse kIow and intci'mitting; the 
breathing labored, aud death supervenes. The temperature through- 
out the disease is seldom increased, unless the disease Iteoomes compli- 
i«ated with acute iutlauimatory discam of tho brain or respiratory 
'orgaus, which often ot^car a» a result of the urea in the circulation, 
Albnmen and tube castt, may frequently be found in the nrlue. Tbo 
diaeoae almost invariably provt\i fatal. 

Treatment. —This muat be directed to a removal of the cause. (See

the animal Bjvtem to a iboek from ligbtoing. Two degrees of electrio 
or lightaing shock may be observed, one prodnciag temporal? coDtrac* 
tioD of muscles and inseDSibility, from which recoreo' i^ possible, th« 
other killing directly, by prodncing a condition of nervoos and general 
iDsensibili^. In shocks which are not immediately fatal the animal is 
osoally insensible, the respiration slow, labored or gasping, the poise 
alow, feeble, and irregular, and the papils dilated and not sensitive, or 
they may be contracted and sensitive. The temperature is lowered. 
There may be a tendency to convnlsions or spasms. The predominat- 
ing symptoms are extreme cardiac and respiratory depression. 

Treatment. — Salphate of atropia sbonid be given bypodermically in 
one qnarter grain doses every hoor or two hours natil the heart beats 
Are invigorated, the number aud fullness of the respirations increased, 
and conscionsness retnms. Stimulating injections perrectom may also 
be useful in arousing the circulation; for this purpose whisky or am-

cnABAGTEBS OP TDK PUI.£BI. 

The circniation of the blood through tbe heart is constant, and ia 
maiiilaine4l by the jiropelling activity of tbis eruau. la the boree tbe 
heart beats from thirtysix to f«iriy-six times a intnute, varyingwith the 
diHpotnition, breeil, uud temperamunt of the animal. In the foul tbe 
pultitt is about three times as rapid as lu the adult, from six months to 
a year about twiiw as quick, and in the two- year old about one-t)narler 
faster. Tht> pulKe it* usually taken at the angle of the jaw, whera the 
artery crosses Ibe bone, and its fiircu or character is often indicative of 
the- nature of the disease from which an animal may Ix^MulTeriDg. The 
pulse, therefore, is named in auuonlunee with iU« character as slow, soft, 
small, fall, weak, (juick, hard, irregular, lutermitteut, venous, etc. 

Slow puhe is one where the n umber of beats are less than normal, and 
is often found in certain diseases of the brain. 

Soft or aimpreasifrle pnUie is one where the beat is ralber weak, l»nt not 
abnormally rapid. It is oftcMt found in debility due to waut of ussimi- 
lation or proper nourishment When iwoompanied with fever or loss 
of appetite it is usually indicative of derau^'uuieut uf tbe digestive 
organs.

DISEASES OP THE nEART AND DLOOD- VESSELS. 

Inonnsidering diseases of the heart we meet with many diOlcnlties, 
depending much upon the position which this organ occupies in the 
animal. Tbu shouldL-i-s cover so much of tho anterior portion of the 
cb«'.Mt, and often m very heavy murteled lior^tes the cbost walls are ho 
thl<'k,th:it a sntixfactory exainiuatiou of the heart cannot be iiiadu. 
I^isi-oMcs of this heart are not unooramon among harHe--«; the heart and its 
lut^uihraiies are frequently involveil in diseases of the respiratory oigana, 
diwasesof tho kidneys, rheiiinatisin, intluenza, etc. Somo of the dis- 
e««AH of Ibis organ are iiHver siisiwcted tty the cirdiiiJiry olwerver

which may frequently denote disease of the heart are difficult breath-

type of infliieiiKa wo may ofu^n And th« heart becoming ini'olved iu the 
disease, in cuufiequence of the morbid material conveyed throuf^h tbe 
Ue-nrt 1 u the blood-stream. In view of the fart tlmt many affections, in 
even remote portions of the body, may be traced directly to a primary 
endocardial disease, we shall feel justified iu inviting special attention 
to thi« disease. 

Biulocarditis may be acute or assume various de^ees nf severity. 
In »<;ute inflammation ire find a tlnckeiitnir and a rouKlieiied appear- 
ance of the en<loran!ium through<mt the cuvitiea of the heart. Thii 
cuiidltion la soon foltowed by a eea^^ulntion of Qbrine upon the infliimed 
RHrfitcp, which iMlheres to it>, and by attrition soon becomes vrorki'd up 
into slircddy-like j;ranular vlovatious ; thi» may lead to the fonuatioa 
of Qbriuuus clota iu the heart and ondden death early in the disease, 
the Hccnnd or third day. This acute type of tbe disonse, however, doea 
Dot alwayii affect the whole interior of the heart, but Ih of(i-n contlnt^d 
to ouo ventriele or may be in patches ; it may extentl through the ventn- 
ola into the aorta or the pulmonary vein ; it may affect the valves prtn- 
eipally, which are composed of but little else than the emIocardimD 
folded npon itself. 

In aouto endocarditis ve invariably niU find myocantitie derelop 
oorre»p<)tiding to ibo uamo npaee, which in intensity may proilnce seri- 
OQi n>Kiilt« through the destruction of funetional ability or lead 1o 
weakness, abaooiis, or rupture. Immediately upoit the swelling of this 
membrane we will Qnd an abnormal action and abnormal sounds of tbe 
heart. 

Subaente endocanlitis, which in the moot common form we meet, 
may not become appreciable for several days after its commencement 
It ii^ehanictirriKrd by Ix-ingcnn&neil to one or more anatomical divisions 
of the heart, and all the successive morbid chauj^es follow each other 
Iu a comparatively slow process. Often we would not be led to suBi)ect 
heart affection were it not for tbe distress in breathing, which it gen- 
erally occjisions when tlic tmimal is exrrciwd, esi>rciaUy if the vidvcs are 
much involved. When the disease extends into the arteries, atherom- 
atons deposits usually develop; when the inSamnintion is severe at the 
origin of the tendinous cnnis they m^y become softened and ruptuml. 
When much libriuuus cuitgula or cclluliir vcgetntiotis form upon Ihs 
tntlanied membrane, either in minute shreds or patches, or when forma- 
tion of fibrinous clots ocear^ iu the cavity affected, some of these matts- 
rials may be cjirrit-d from tbe cavity of the heart by the blooil -current 
into remote organs, consti ruling emiMdi that are liable to suddenly plug 
vessels and thereby interrupt important funcltons. In the great m;^or-

which will lessen the irritAbility of the heart without wetkkeDiDf; it; i

and hy|>ertro[)hy. So long ns there is aii innt-enso of temperature, with 
BOue ilejrree of ncauliueita or the uriue, it may b« mare to lM>lieve that 
there ia some degree of inHammatory action eziatiiig in the cardiac

however moderate in degree, there in a tendency to increase or hyper-

Tbe tinotare of diKitolia, in 20 drop dosos, rop«at«d every hour, ia 
perhapN the most reliable agent we know to eoiit.rol tbe irritflbility 
of the heart, and thio also h»s a dec'tded influence ui>ou the uri- 
nary secretion. After the desired impression npon tlie heart ieob- 
tained the doso may be repeated every two or three hours, or ae tlie 
case rnuy demiind. Fluid extraut of eonvaltaria majalit, tu 2-dnuB 
doftea, will quiet tbe tumultaous action of the heart in some cases wbers 
thedigitalift fails. Some vuterinarinns recommend bleeding, others cold 
paeka aronnd the chest or over tho heart. The former is decidedly 
objectionable, becfinso of its Ct>ndeiicy tu favor Hbriiious exudation andfl 
olot formation ; tbe latter is too risky a proceeding in the majority of V 
cases to warrant its use, for we find this disease in wet ami damp ata- 
blea in tbe moat a.i;gravated and fatal forms. Blistering and ^ttmulat- 
ing api)Iioati«iis to tho ebest should also be avoided. They nerve to 
irritate the animal and can do no possible good. Gblorato of iiotassa, 
in 2 dram do^fs, may bo given in tbe drinking water every four boars 
for the first five or six days, and then be 8U|>erceiied by the nitrate of 
potassa, in half-ounce doses, for the following week, or until tbonrlnary 
secretion becomes abnormally prolnse. Wliere the diKeiise is associated 
with rhenniatiHm 3-dram dones of salicylate of aoda may be sulwiitated 
for the chlorate of potai^sa. To guard against chronic indnralion of tbe 
valves the iodide of potossn, in one to 2-dram doses, should bo given 
early in the disease, and may bw Repeated two or thn« tiuii'H a tlay for 
several weeks. When chronic effects remain after the acute atage hat 
passed tliis drug be<.omen indispensable. 

When dropsy of tbe limbs develops, it i« due to weakened circniation 
or functional iiupairniont of tbe kidneys. Wbeu tbert- in mueb weak- 
ness in the action of the heart, or general debility is marked, the iodide 
of irou, in 1 dram doses, curabined. with hydnuttis, A drams, may bofl 
given three times a day. Arsenic, inS-graindosestwiceaday, willgive 
excellent results in some cases of weak faeart a^aoeiated with diOioult 
breathing. In all caxes ab»ulnte rest and warm stabling, with comfort- 
able clothing, beoomes necessary, and freedom from work should ba^ 
allowed lur a loag time after ail symptoDDt have disappeared.

PUNCTIOSAl, ASD OROAISIC DISEASES OF THK HKABT. 

The distinction between fuuctional and organic diseases of the bea 
is not ejiRily made. >Ve may accept as n guide that the character of' 
or|;unic diseases of the heart is to progress, and that of functional to , 
occur at regular Intervals. Active exercise almost invariably ap| 
vatcs orgiinic, but seldom increases the 8ym]>t(>riisorfuu(;riiinal dif 
and that the physic^d mgiis generally are soon developed, and reooBii 
psruiaoent in organic, vhile,they seldom exist in fnoctionaU

readily to the exciting cause, which we may be able to avoid or over- 
come in the future and thereby obviate subsequent attacks. Rest, a 
mild stimulant, or a dose or two of tincture of digitalis or opium, will 
generally give prompt relief. When it ia due to organic impairment of j

THBOHUrS ARD EMROLISU. 

By thrombosis is generally noderstood the partial or compIetectosfS*^ 
of a vessel by a morbid product developed at the site of the obetm*'' 
liou. The coagulum, wliiuh in nKuallv llbrtuoiiii, is known as a throf** 
'boB. The term embolism designates an obstrnction cansed by any botl^ 
detached anil transported from the tnterinr of the heart, nrnfnome ve^ 
wl. 'Jlironibi owur aa the resnlt of an injury to tho wiill of the 
ormay follow its compreaston or dilatation ; they may result from 
alteration of the whII of the vesisel by dlBease, or by the retardatli 
the circulation. Theue formutiuuH may occur during life, in the heart, 
arteries, veins, or in the porlal system. Whena iwrtion ofQbriucoag' 
ulatea in oue of the arteries and is carried along by the circulation, il 
will be arrested, ufcourxe, in the capillaries, if not before; when in the 
veins it may not be stopped iiutil it reiichcttthe luugs; nud when in tbo 
]K)rtal system thecapillariesof the liver will prevent ilefnrtherprogreM. 
The formalmn of thrombi may act primarily by enusiug partial or com- 
plete (ibstmet ion, and wcondarily, either by larger or xnialler frag* 
menta beconnng detacheii from their end, and by being cwrried oloae 
by the circulation of the blood to remote veuela, embolism ; or by tte

tendinons conis, the deposition has occurred more or less remote from 
tLe act of dying. Occasionalty the fibrin may iHiseen liningoneof tl^ 
caritiea of the heart, like a false enduiuirdium, or else forming an addi- 
tiuual coat to the aorta or other large \-es.sela without piwlucing mucb

The lymphatic or absorbent system is connected with the blood' 
cular HyKtcni, and <H>nsiHt4 nf a ncriuii of tubes whicli absorb and oonl 
to the blood certain Huids. These tubes lead to lymphatic elands, 
through wUieh the fluid» pass to reach the right lymphatio vein and 
thoracic duct, Iwth of which enter the venous system near the he&rk 
Throuf^h the exoussively thin walls of the ciLpillaricM the Huid part of 
the blood transudes, to nourish the tissues outside the capillaries ; at 
the same time duid parses from the tissues into the blootl. The lluitl, 
after it passes into the tissues, oonstitotes the lymph, and aeia like a 
Htrt>am irrijo^tiug the tituiuc elements. Much of the Hiirphis of (his

tbe eye of inau, bnt it server iu ttio lower animals to assist lu ntuiovlng 
forei|:n bodies from the fmnt of the eyeball. It consists, in the horse, 
of a cartilage of itrcgul.ir form, lbi<:k(;ned iiifvrioily and posteriorly 
where it Is intimately connetited wi'.b the miiM^es of the eyeball, and 
the fatty material aronnd them ; and espanded and Ihittoiied anteriorly 
wbero its uppur snrfucu In connave, and, aa it were, monldeil on tbe 
lower and Inner surface of the eyeball. Kxterually, it is covered by tbe 
mucous membrane wbieb tines the eyelids and extends over tbe front 
of Ibe eye. In the ordinary restful state of the eye tbe edge of this 
cartila^re shoald Just appi'^ar aa a tbin fohl rif membrane at thti inner 
AUgIc of tbo eye, but when the eyeball is drawn doeidy into tbe orbit 
Uic cartilage is pushed forwnni, outward, and upward over it until tbe 
entire globe may be hidden from sight. This protruNinn of the <:arti- 
luf^r, »o as to cover the eye, may bo induced in the bealtby eye by 
pressing tbe flnger and thumb on tbe upper and lower lida. so aa to cause 
rctnii'tion of the eyeball into its socket. When foreign bodies, such 
as Baud, dust, and ehafi', or other irrituntA, have falUn on tbe eyeball or

This consists, flrst, of a gloud for the secretion of the tears, and, fteu- 
ond, of a series of canals for the oouvcyauce uf the superduous teurs 
Into the cavity of tbe nose. 

Tbu iilaod is situated above the ouu^r part of the oyebaU, and tbe 
tears which have llowetl over the eye and reached the inner aagte art 
there directed by a small conical papilla (lachrjfuial earuucle) into two 
niiuule oriQces, aud thence by two ducts (lachrymal) to a small pouch 
[Inchrymal biu*.) from which a canal leads through the bones of tbe fiive 
into tbe Doee. Tbi^ opens in the lower part of the uose ou the fli>or of 
the passage, and a little oatside tholiae ofnnionof the skin which lines 
the false noRtril with the mnraus membrane of tbe nose. In tbe ass 
and tniile this o|>eniug is situated on the roof Instead of tbe floor of the 
nose, but sLitl ciosii to the external opening. 

BXAMiniTION OP TUE ETK. 

To avoid nnnpcpjigary repetition tbe following general directions are 
given for tbe exainlnalion of the eye: Tbe eye, and to a certain extent 
tlie mncoas membrane lining the eyelids, may be exposed to view by 
gently parting the eyelids with the thumb and forefiuger pTe«»ed on 
tbe middle of tbe res|iertive lids. The pressure, it is true, causes tbe 
protntsion of tbe haw over a portion of tbe lower and Inner part of the 
eye, but by gentlenesH and careful graduation of tbe pressure tbis rnnf 
be kept witbiu bounds, mid ofleiitiineMoven tin; interior of the nyc can 
be seen. As a rule it ia best to use the right hand for the left eye, and 
the left band for tbe rigbt^ tbe finger in each case being pressed on tlie 
npjM^r lid while the thumb dnprt'sncA thii lower one. In rxgps in which 
it is desirable to examine the inner side of tbe eyelid farther than is 
possible by the above means, the npper lid may tie drawn down by th« 
ej^elashes with tbe one band and theu overtetl over tbe tip uf the for*-

The eyelids often undergo extreme infiarnmiitory and droi>sical swelling

The affection will, therefore, readily diride itself into (I), inflamma'

the absence of any local vrouud. and the history of a low damp pasture, 
exiKntaro, indigestion from uawholosomc food, or the presence eUowbera 
on the limits or liody of the genenil doughy Hwellingtt of purpntft 
baemorrhagioa. The lids are swollen and thickened, it may be slightly 
or it may l>e so extremely that the eye ball can not be seen. If the lid 
can be everted tc show its mucous membrane, thut is seen to be of a 
fleep red color, especially along the branching litiesof the blood vessels. 
The piirt is hot aud paiuful, and a profuse Qow of tears and muuns 
escapes on the side of the face, causing irritation and loss of the hair. 
If improvement follows* this diwchartce becomes moro tenacious, aud 
tends to cause adhi>ttiou of the edges of the upper aud lower lids and

scabies (mango) iut^cut iuto the eye, smoke, aiuoionia risiog from tbe 
excretioiiH, irritant ematiatioua from drying marshes, etc. A very dry 
air is alleged to act injuriously by drying the eye as well as by favoring 
the production of irritant tlust ; and the undue exposure to bright »uu- 
eliiue through a vrindow in front of the dtall, or to tho redectiou frot 
gnow or water, is nudonbtedly injurious. Tho nnprotrnted expoHure i

rank, itqueous, and deficient in assimilable principles they lend to lower 
the henlth aiid open the way for the disease. 

The period of dentition and trafuing is a fertile exciting cause, for 
tbougb tho malady may appear at any time from birth to old age, yet 
tbe groat majority of victioia are from two to six yoars old, and if a 
horse escape-s the nftectioii till after Mix there is a reaKOuable boiw that 
be will contiuuH (o resist it. The irritation about the bead during Ui« 
eruption of tbe teeth, and while fretting in the unwonted bridle and 
collar, the etimalating grain diot and tbe close air of the stable all com- 
bine to rouse tbe latent tendency to disease in the eye, while direct 
tpjories by bridle, wliip, or hay-seeds are not witboat their influence. 

In the same way local irritants like dust, Hovcru rain and (tnov* 
stornia, smoke and acrid vapors are contributing causes. 

It is evident, however, that no one of iheso is sufQcieot of itaelf to 
produce the disease, and it has been alleged that the true caM.s« is a 
niicrube, or the irritant product-s of ti iuicn>bc, wbicb is harbored in llie 
marshy soil. Tbe prerateuoe of tbe disease on tbe samo damp scilft 
vhtch produce ague in man and anthrax in cattle has bt^'en qnoteil in 
support of this doctrine, as also the fact that the malady is always 
more prevalent caterin paribun in basins surrounded by hills whero 
the air is still and such products are concentratrd, and tbat a forest or 
eimt>le belt of trees will, as in ague, at times limit the area of ita prev- 
alence. Another argument for thi< same view U found in the fact that 
on certain farms irrigated by town sewage this malady has become 
extremely prevalent, tbe eewaeo being assumed to form A eaitable 
□idus for tbc growth of tbc germ. But on these sewage farms a Tnsh 
crop may be cut every fortuight, and tbe |>rodueL is precisely that aque- 
ous material which contributes to a lyniphiitic atructuro and a low tone

of hicomotion irreH[>ective of Ihe eaiiHe which pnxtueed it or the (le- J

irith the best chances of an intolligcnt decision, aud it is while moving 
with tbat gait, therefore, tliat the points should be looked for whicii 
must form tbe oleineats of tbe diagnosis.

two hi nder, tlie posterior ; the two on one side, tbe Uiliral ; and one of 
eitlier tbe frout or bind bii>ed with tbo opposite leg of the hind or front 
luped will form the d'lasotial biped.

Considcriog, as it is proper to do, tbat in a condition of bcalth cacli 
Bcpnrato biped and eaub fudirldual leg is required to perronu aa equal 
aud miiforiu function and t o carry an evni or equal port ion of tlmweiglit 
or tliu body, it will bu ntadily apiirufiatetl tbiti (bo rvsidt uf (liiii etitial 
dislhbutioB will be a i-egular, eveoly bnlauced, uud emootb displace- 
mout of tUo bwly tbiis supitortetl by the four legs, and tbat therefore, 
according to tlie rapidity of tbo motion in different gnits, encb siii^lo 
leg witt he. nHiuirud ut eertaiii Ruc;i:eii$tve momeuls to War (be weigbt 
wbicli bail rested upou its congener wbilo it irns itself iii thu nlr, iu itic 
act of inoviag ; or, ngatu, tn'O dtB'er«nt lege of a biped may l>e called 
upon to boar tbe vciglt of the two legs of tbe opposite bipetl nbile 
also Iu llie air iu the act of moving. 

To simplify tbe matter by au Illustration, tlie welgbt of an animal 
may bo placed at 1,000, of Tvbicb eacb leg, in a normal and bealtby ooa- 
dition, supports wbilo nt rest S^iO. Wlien one of tlio fore legH is in ac- 
tion, or ill 1 be air, and earr>-iiig no weight, llsSSOabaro of ibe veigbt 
will bo thrown npon Itscotigener nr partner to sustain. If Ibe two legs 
of u biped arc both in actioiiand raitH-d from the tiround, their congcuere 
atlll resting in inaction, will carry tbe total weiglit of the other two, or 
500. And as tUo succession of luovemcNtM coutinnes, and th» change 
from one leg to another or from one biped to anotlie:', as may be nv 
quired by tho gait, procrcda, tbero will result n smooth, creu, and equal 
balancing of active nioremeiits, shifting the weight from one leg or one 
biped tu another, with symmetrical precision, and no ahall be preseoted 
witb au interesting example of tbo play of vital mechanics ia a bealtby 
organization. 

Much may bo learned from tbo aocurato study of Ibo action of a 
siiiglu leg. yoriiially, its nioveiuentK will be withuul variation ur fail- 
ure. When at rest it will easily sustain the weight assigned to it, with- 
out showing hualtancy or betraying i>aiu, and wlioo it is raised front 
the ground in order to transfer tbe weight to its mate, it will iterform 
the act iu such a manner tbat when it ia again placed u(H)n the ground 
to rest it will be witb a firm tread, indicative of its ability to leceive 
again the burden to be thrown back upon it. Iu jdaiitiug it u|Kin Iho 
ground or raising it up again for the forward movement while in action, 
and again replanting It upon tbe earth, each movmnont will hn ttao 
same for eacli leg and for each biped, whether tbe act l»e that of walk- 
ing or trolling, or even of gallo|iinK. In shorty thu regular phiy of 
every part of the aiipanttus will tustify to tbe existence of tbat coodi- 
tiou of orderly sDuudnes^ aud efflcleut activity which is cloquentlysug- 
geslive of the condition of vital integrity, whicb is simply but compro- 
heuaively expressed by the terms IieaUh iind HOHndnrxa,

irTu^jular outline, and at o1hi>rs projcctiog distinctly from tlii* surface 
from wbicb it NpringK, »» so commonly prfNCiiteit in tlic riiigbouo and 
the Kpaviri. Tiiis couiiitioa of j>erioBlitia is ofleii diflicult lodeterinijie. 
The fiigus of inflammation are so obscure, tbe spelling of tho parts so 
insiguiQcnnt, any increoso of licat so impotc^ptiblv, and (Iki Korenrss so 
slight, that even the moMtacute observer may fail to locate tlio ]>oiiil of 
Ittt oxtstetice, and it is often long after tlie discovery of the disensu itself 
that its location is iiositivcly revealed by the viBibK'preaeneeof the exos- 
tosis. Yet the first question had l)«en resolved, in tiiscovering the fact 
of the lameuesa, while the second iiud third remained unanswered), and 
the identification of the aflfected limb and the iwint of origin of the 
troiiblo reinaniuil unknown until their palpable revelation to tho senses. 
Wbeo, by careful scrutiny the ailment has been tiwated, n resort to treat- 
ment must be had at once, in order to prevent, if iiossiWe, any further 
<Iepo:iit of the calcareous strncture ami increasLi of iht^eTostotic jjrow ili. 
With this view Iho application of water, either warm or cold, nindered 
astringent by the addition of alum or sugar of li^ad, will be beueflciAl. ^ 
The teudency to th» formation of the bony gmwth, and the increaseof H 
its development after its actual formation, nuiy often be checked by the 
application of a tteverii blister of Spauifih fly. Tho failuru of thi-tuj means 
and the eatablisbmeut of the diseased process in the form of chronic 
periostitis ciiuses various elianges in the Imne covere*l bythedlsordetvd 
meuiliraue. and thu rt',-*ult may be softt^ning, degcnuratimi, or necrosis, 
but more usually it is followed by the formation of the bony growths 
refeiTed to, oathe caution bone, the coronet, tho bock, etc 

We first tarn onr attention to the splint, ascertain boa; enlargcmonts 
whicharudevetopetlonlhecannnnbone, betwtrnnihe knceorthehockaud 
the lellock joint, are called. They are found on the inside of the ley, 
fromlheknee, near to which they are to be tound, downward to about the 
lower third of tho principal cannon bone. They aro of various dimen- 
siona, and are readily pen-eptible both to the eye and to tho touolL 
Tbey vary considerably in size, raugiiiB from that of a larce iitit down- 
ward to very small proportious. In searching for them tbey may be 
readily detocte<l l)y the hand if they have attained siifflcicnt develop- 
ment in their usual situation, but ninnt be distinguished from a small 
bony enlargement which may bo felt at the tower third of the cannon 
bone, and is not a splint nor a pathnloj^-ical formation of any kind, bat 
merely tlie uormal developtneut of the small cannoo boue.

Ihut ia trut! as a geueral titatouvut, but it is not invariably so, and they 
docaaiotially appear on the oatside. It is also trae that tliey appvar 
mo3t commoulyon tbo fore legs, but this is not exclusively the ca«e, and 
^hey may al timua 1h> found on both tht; insidn mid ontAido of llie hind

^>€il!/ed gplint, and c«nMtitutOB a seriouH and pennaueat deformity, iaooa- 
^Kqueuce of its interforuuco with the play of tho Bbroutt curd n-bicli 
2)aA»ies behind it, l>ecuiniug thua a Houroe ufcoutinoal irritation and cod 
•eijaently of permanent lameness. 

A. splint may thus frc-4|nciitly liccomn a caone of lameneH« tltnu^h not 

'Sieoeesarily in erery instance; bat it is a Jauieuces possessing fvaturoa 

peculiar to Itself. It Is not always continuous, but at timea nsHumeft 

An inlermitlcnteharact«r,and is more marked when the animal is warm 

than whvQ bo is ooul. If the luiDone^s is near the knee-joint, it is very 

apt to become aguravated when the animal is pat to work, and the gait 

acquires then a j>eculiar character, arisin;; from the manner in wliicb 

tho limb is carried outward from the kuee.<i downwards, which is done 

by a kind of abduction of the lower part of the log. Other nymptoma, 

liovever, than the lameness an<l the presence of the splint, which is its 

«iaae, may be lookeil for in tbe same connection as those which huva 

been roentioniHl as p«'rtainiiig to certnin evidences of perinstiliH, in the 

Increase of the temperature of Ibo part, with swelling and probably 

potoon pressure. This last symptom is of no little importance, siooe ! 

itc presence or absence Las in many cn^tos formed the determining point 

in dectdingu qucnbion of difTii^iiIt diagntisi.s. 

A splint being one of the n^ults of peri ostitis, and the latter one of 
tbeeRectsof external burls, It uatarnlly follows that the parts which 
are most exjmned to blowH and collisions will I>e those on which the 
splint will most commonly be found, and it may uot be improper, there- 
fore, to refer to hnrta from wtthoac as among tbe common causes of the 
lesion. But other <uusc8 may also be productive of the evil, and amon; 
tlieoe may bo mentioned the ovemtniiuing of an immature organism by 
tbe imposition ofexce.ssive labor upon a young animal at a too early 
period of bis life. The boacs which enter into the formatiozL of ttid 
cannon are three in number, one large and two Kmatli>r, which, during 
the youth of the animal, are more or less anleulated, with a limited 
amooot of mobility, hat which become in maturity Qrmly joined by a 
hgid anion and ossifioatiou of tbcir intiT articular surface. If the im- 
nalnre animal be coupolled, thtan, to pi^rrnrni exacting tasks beyond 
bis Ntrenglfa the ine^Htahle result will follow in tbe muscular straining,

acntc symptoms may bo followed by a new pathological activity wbicli

It ia of course the consideration of the cornpaniliro UaniilesKiiesn of 
splints that siiggestN and just ifiiw the poliry of nou-intprferenee, except 
as they become a positive cause of lamc-ucss. And a more [lositire 
nrgameut for such voa-interrerenoe consists tn tbe fact that any aclire 
and irritating treatment may so excite the purls as to bring alinttt a 
n^newedjKithu logical activity, which may result in a rednplicjttion of 
the phenomena, with a second edition if not a second and cnlnrgrd vol-

Niinplu n'»soii, a.U)Uiig many others, that they tend by the prouiplueiss 
of their acliuu to preveut by auticlpatioa the formation of tbo bony 
deposits. The lameness will often yield to the blistering action of can- 
tharidcs, iu the form of oiutiuoDt or liDimout, and to tbo alt«riktire

Tbe removal of the bony tumor can not be accomplished by aoy axuh

Tbiti auliitiuu of cuntinaity may take place in tiroprincipiit ways. In

tbe tbivkneJsx of tbe bone, nuil for t bat reason is demerit khI as ijtramj}/e(«. 
If tbe bone Is dividetl into two Kcparato portions, aud tbe soft parts

The coudition of dis]>lacemeDt id largely intlaetitial to determining; 
the qucatioD of treatmeut, nod flsnflocting the final ivsult of a c&se of 
fracture. Thio, hnwe%'«r, i.t depRiiil«iit upon ItK lociition or whotiior its

beloDuing to the intra periostval clasa. At times, also, there is only a | 
Ajtiiple tla.sure or split iu tho bone, makiug a cotiditiou of mach difflcultj 
of (lidgiioma. 

Two varieties of originating cnnse may be rooognized in eauett of frac- 
ture. They are the prediapt^sing aud the occauionai. Am Ut the Qrst, 
difl'erent spectett of iiDimais difier in the degree of their liabilily. That 
of the dog iei greater than that of the horse, and, iu horses, the variuas 
queationH of iige, the mmle of labor, the season of the year, tho portion 
of the body aiost exposed, and the exiatence of ailmentA, local and gen- 
eral, are all to be taken into account. 

Among horses, Uio.se employed in heavy drangbt work or that aro 
driven over bad roads, are more exposed than light<drangbt or aaddto 
horseti, andaiiiuiaJM of different ages are not eipially liable. Dogii and 
young hor«e«, with those which have become sulllciently aged for their 
bones to have acquired an enhanced degree of frangibility, are more lia>{ 
bio than those which have not exceeded the time of their adnlt priui& ' 
The 8eai:uu of the year is undoubtedly, though in an incidental vay, 
an Importatit factor in the problem of the etiology of these accidents, 
for Ihniigli they may be observed at all timr-A, it is during the months 
irhL-n the etippery condition of tho icy roads reudera it dilSi-uIt for both 
men and beasts to keep their feet that they occur moHt frequeully. Th4 fl 
long bones, those especially which belong to the extremities, are most ^ 
frequently tho seat of fractures, from tlio circumstance of tbeir super- 
Acial position ; their ex|>osure to contact and collision, and the violt-nt 
nmscular efforts involved both in their constant rapid movcmeui aud 
their labor in the abafta or at the pole of heavy and heavily laden car- 
riages. 

The relation between sundry idiosyncrasies and diatbesea and a 
liability to fractures is too constant and well established a pathological 
faol to need more than a passing reference. The history of rachitis, of 
melanosis, and of oKte(>-pori>.'iis, un rvlated to an abnormal fVaugibility of 
the bones, la a part of our common medical knowletlge. There are few 
persona who have not known of cases auoug their frieade of ft^qnent 
and almost siwutancons fractures, or at least of such as seem to be pru-

due to the exudation of Mie blood into the me^hos of tho siirnmuding

A<2cl usefiilnoea. Considered per se, a fracture in an animal is in fuel no 

'^•^s ntncnable to treatment tban tbe aume deiicnplion of injury in auy 

**tln>f ijring beiug. But tbe qnestiou of the proprioty and expediency 

^^ treatment its dependent upon certain speciSc points of collateral cou- 

^^ «rati«ii. 

-i^nt. The nature of the lesion itself is a point of paramonnt impor- 
'^'ttiie. A simple firaoture occurring in a bone where the ends eau t>e 
"■"tiily secured in coaptation, pr««cnLs tho most favorable conditions for 
^^«:5cessful treatment. If it be that of a long bone it viU be the lesa 
*^>*ioa8 if situated at or near the middle of its length than if it were Ln 
*^"C»M proximity to a joint, from the fact that perfect immobility pan 
'^t^ly, in the latter caMe, be secured without incurring tbe risk of 8u1>- 
**tloent rigidity of the joint, 

A simple is always less serious tlian a compound f^actnro. A corn- 
limited is always more daugerotis tlian a simple, and a tniiisventa 
^itiiik is easier to treat than one which is oblique. Tbe most ^e^io^8 are 
^ho»e trhicb are situated on parts of the body in which it is ililHculC to 
BFcnn^ I>erfe«t immobility, nnd eBpeotally those which are accompanied 
br suvore coutaMioiiM and lacerations In tbe soft parts; the protrusion of 
frjsineiitw tbroiigli tlie skin; tbe division of blood vessels by the broken 
Ri<bi of the bono; tbe existence of an articulation uear the point to 
irliiob indammation is likely to extend; the luxation of a fnigment of 
the bone; laceration of tbe periosteum; tbe presence of a large number 
of biiuy particlew, the result of llie rrushing of the bone — all these are 
Circumstances which discourage a favorable prognosis, and weigh agaioat 
tbe hope of saving the patient for fhture nsefnlnoiis. 

Fractures which may be accounted curable are tho-ne wbicb are not 
ooDspicuously visible, as those of tbe ribs/where displacements are 
either very limited or do not occur, the parts being kept in situ by the 
;re of thftir position, the shape of the bones, tbe articulations they

The mctbodfl of accompUsbtiig reduction vary with the features of 
each cniw, tbe mnnipuIntioDs being necessarily inodJIicd to mc-L-t cimug- 
lug Gi^(^um(lUl»<H;M. If tbti tlisplucuiiu-ut iti in IbetbickiiesHof tbebone, 
as iu transverse fracture, tlie uianipulntion of rvtiuvtion i»ii»i8ttf in 
applying a stcfwly pressure upon one of the fragmoutfi, while tbe other 
is kept steady tu its place, the object of the pnissuro being IUb r<xs- 
tublishment of the exact coincUlcniMi of the two bony surfaces. If the 
displacciucut bus taken place at an angle it will bo suDi(.-iL-nt iu order 
to eft'ect the reduction to press upon tbe sucnuiit or apex of the angle 
nnlil its disappenranco indicates that tho jMirts biive iMK-n brought into 
coaptation. This method in often practiced in the treatment of a frac- 
tured rib. In a longitudinal ttaoture, or when tbe ft-agmcnta are 
pressed together by tbo contraotiou of tbe mnsclcs to nliicb they give 
insertion until they so overlap as t<o correspond by certain points of 
tbefr circumference, tbe reditutiou is to be acoompUsbed by effcetiag 
llic movenientsof or/ffiMiVit, counler-extention. and coaptatiou. Exteusiou 
is accomplished by making traction upon the lower imrtioHofthe limb. 
Oountorexteusion oousists iu firmly bolditifir or couQuiDfT the upper or 
Imdy portion in such a mann<>r that it shall not be ad'ected by (he trac- 
tion applied to the lower; iu simpler laut^uage, buldiug it motionleM 
against the force exercised in tbe extension. In other words, the 
operator, grasping the limb below the fracture, draws it down or away 
fnim the trunk, while he Keekd, not to draw away, but simply to hold 
BtiW tbe up|>er portion until the broken ends of bone are brought to tbeir 
Dtttiiral relative positions when tho coaptation, which is thus atlVcted* 
has only to bo made permanent by tbe projier dressings to perfect the 
reduction. 

In treating fVacCures in small animals the strength of tbe hand is 
nsually salBcient for the required oiauipulations. In tbe fracture of 
tbe forearm of a dog, for example, vrbile the upper segment is flrtalj 
held by outi baud, tho lower may bo grasped t>y the other nnd tbo bona 
itself made to serve tbe purpose of a lever to bring abunt the deaitcd 
coiiptnlion. In such a case that is sufficient to overcome the musca- 
lar contraction and correct tbe overlapping or other malposition of tlie 
bones. If, however, the resistance can not l»e overcome iu this mode, 
the upper segment may be comu^ltted to an assistant for (bo manage- 
ment of tbe couuter extension, leaving to the operator the ft«e nse of 
both bands for the further manipulation of tb« case.

Of the cranial hone». — Frai:tiir«D of tliiH variety in Iarj;i> nnimalH are 
eoiuparatively rare, tUongh the revonls are not deKtituto of ca-^s.

U{)oii the halter bare broken it with » Jerk and been thrown backwarda, 
as lulfihl i»ct!Mr in reariug loo violently. Under thcRo comlitfona we 
have witnessed fractnre^i of the parietal, of Ihe frontal, and of the 
aphetioid boiiea. These fractures nuiy be of both the complvtc and Ui6 
incomplete kind, which indeed is usually the case with those of the Sat 
tx)ne«, and they are liable to be coniplicAted wltb laceintionB of the 
((kin, in couHequenMs of wliich they are «ra8ily hroughc under obnervfr 
tion. But when the fact is otherwise and tlie skin is int<tct, the din;;- 
□oeia bccuulis diflictilt. The incomplete variety may bv unacoompanicd 
by any special symptoms, but in the complete kind one of the Imny 
plate8 may be so far detachml a» to pre&» ujmii thu cerebral Mnbitlance 
with siiQicient force to produce eeriona nervous comptioations. WUcd 
the iojary occurs at the base of the cranium hcraorrbngemoy bo looked 
for, with paralytic symptoms, aud when these uro present the nsnal ter- 
mination in death. U may still happen, however, that the ayntptoiua 
of an apparently very severe txincussiun may disappear, with the reautl 
of an early and complete recovery, and the siirgiMin will therefore do 
well to avoid undue precipitation in venturing npon a progoosis. la 
fractures of the orbital or the Kygoniatio bnn<>s (lie danger Is le^ press- 
ing than with injuries otherwi»(e located about the head. The treatment 
of cranial ft-actun-u is simple, though iuTotving tlie bent Hkill of tha 
experienced surgeon. When incomplete, hardly any interference la 
neeiled; even plain bandaging may uKually Im! disptfn&ed with. In the 
complete variety the danger to be combated is compression of tb« 
brain, and attention to this indication mnst not bo detayetl. The meaua 
to be employed are the trephiuiug of theekull over the seat of the H-ao- 
tnrc, and the elevation of the depressed bone or the removal of the fl 
portion which is causing the trouble. Fragments of bone in oommlun- ' 
ted cases, 1>ony exfoliations, collections of flaid, or even protmding 
]Mirtiiiii;4 of the brain suhHtancc uinst he cjin-fully cleansed away, uuda

dressings. 

Fracturea of the itynat of the face. — In respect to tlielr origin — nsually ' 
trantnatic — these injuries rank with the preceding, and are commonly of

varying fumplicatioits of tUesc accidents. Tbe object of tlie treatmeut 
elioiibi be the restoration of the depressed bones as nearly aa possible 
to ibeir noriiml position, and tlicir retention in pinoe by protecting 
H]ilint.s, nliicti kIkmiUI cover tb« entire facial re;;ion. And Kpeoial pre- 
caatious abonld bo observed to prereot tbe patient from disturbing tbe 
dressing by rubbing his licad against earroiinding objcctit, snob as tbe 
Btnl), 'ha manger, Ibo rack, etc. Cluta of btoo<l in tbo uasnl pnHsages 
maat be vnslied out, colleolions of pus ninst Iw removed from tbe 
Kinases, and if tbe teeth are loosened and likely to fall ont, tbey sbouLd 
be removed. If roaring in tlirentened, tracbentomy is indicated. 

Pfttcfurei o/the prem<ixiUnry bone. — These nro mentioned by cent 
nenliil authors. They arc. usually enconiitered in eonne<.<tion with fme-"^ 
luri-8 of tbe nasal bone, and may take place either in iho width or tbe 
length of the bone. 

The deformity of the ap]>cr lip, which is drawn sidewiso in thislcsionf 
renders it easy of dfsgnosis. Tbe abnormal mobility and tbo orepito* 
tloii, with the pain manifesteil by' the patient when nndergotng ex- 
aniinittion, are concurrent symptoms. Looseness of the teeth, iihuu- 
dsDt salivation, and entire inability to grasp tbo food complete the 
symptomatology of these accidents. In tbe treatment, splints of gntta 
pprt^iia or li'atbor aru KumeliineH u»ed^ but they are of diQiuult applieo- 
tiou. Our own judgment and practice are in fapor of tbe union of the 
bonen by means of metallic sninres. 

The totefrjaic. — A fracture hero is BOt an injury of infrequent oo- 
eurrcnce. It Involres the body of tbe bone, at its KymphysiH, or baek 
of il, and inclndes one or both of its branches, either more nr less for* 
Wiird, or nt the posterior |mrt, near the temporo maxillary iiiticnlutlon, 
at Ihu coronoid process. 

Falls, blofl's, or other external violence, or iwwerful mnscutar con- 
traottous during the use of the speculum, may bu mentioned among 
tbe causes of tbtx U'^ion. The fractnre of the neck and of the bmnchei 
in front of the checks cau^cs the tower Jaw, tbe trite denlid arch, to 
drop, n-lthont tbe ability to raise It again to tbe U|iper, and tbe result 
is a peculiar and cbnracteristic physiognomy. The prehension nnd 
muoticution of food become imimssihle; there is an abEindaiiC escape ol 
fetlil and sometimes bloody saliva, es)>ociiilly if llie gums liave been 
woundcl ; there is excessive mobility of tbe loner end of the Jawbone] 
and tliere is cropiiatton, and fretjaently paralysis of the under lip. But

Tho paitictiljr sent of the injury, with its ttpcciul features, ttiII olfl

and fur thin special splints aro uoccssury. [n a frnelui-o of tho syui- 
pbysis or of the bnmuheti the adjustment of the fragmeiitH by tiecurin| 
them witli metallic sntures is the Hut step necessary, to be folloned by] 
the application of snp[inrls, aMixidtinj: of splinta of leather or sheeli 
of metal, the entire front of the head being then covered with bandages 
prepared Tritb ndhoKive mixtureii. During tho entire course of trcaC- 
uienL a special method of feeding becomes necessary. The Inability 
tlie patient to appreciate the situation of course necessitates a r«soi 
to an artificial mode of iulrodueiug the nece^ary food into his -itomau1i,1 
and il is aecoiupUslied by forcing between the comnii&surcs of the lips, j 
in u li(]uhl form, by means of a syringe, tho milk or nutritive gruelf] 
selected for Lis sustenance, uuttl thn con;itoltdation is sufficiently ad* 
vanccd to permit the ingestion of food ofa more solid consistency. Ttie 
callus will usually bo sufficiently hardened in two or three weeks to al- 
low of a eb.Tngo of diet to maahes of cut hay and scalded grain, until 
the removal of tho drcsNiug rcuttoreshini to his old habit: of musticntioQ' 

Fritctu)c/i of rtriehrar. — These arc not very commoD, but when tht.'y do 
occur the bones most frefiuently injured aro those of the back and loiua. 
Tlio ortlinary causes of fracture are responsible bere as elsewbcro, saelifl 
as heavy blows on the spinal column, severe falls while coQTejiug hca%-y^ 
loads, and especially violent ellbrts in resisting tho process of casting. 
AUbougb occurring more or less frequently under the latter circnm- 
stancca, the accident \» not always attribntablu to carele^^sness or error 
in the mnnagemeut. It may, of couriie, sometimes renult from saeb a 
cause as a badly prepareil bed, or tho accidental presence of a banlj 
body concealed in tlic straw, or to a heavy fall \rhcn tho movements i 
the patient have not been sulUeieutly contmllcd by an ufTeotiro Rppa*

the violent re-sislanec and the consequent powerful ninscnlar oootnuv 
tion by the frtghtonc<I patient. The simple fact of the overarcbing of 
the vertebral column, with excessive pressure against it from the int«s-

tile posterior jwirt of the tnink wliilo the anterior porliou continufs to

Iioirever, npoo the removal of the boVtbles, only the fore part of the 

hoily will respond to l\n* eflorl, a degreo of paraplegia being present, 

and while the head, necb, aud foro part of the body will be raised, the 

bioil quarters and hind k^gs M-ilt remain inert. Tho nnimal may pcr-

tliedigptaeemeut of tho bune will follow, couverting tbo fracture into 

one of tho complete bind, either through tho exertion of walking or by 

a rcaeved attempt to rise after another fall, before teaching bis Blall. 

Ey this timo tho i>aralysls iscinnplete, and thocxtension of tbo luealn- 

l^lis which has become established is a cousuaimatioa soon reached. 

To say that the jirognosis of fracture of the body of tlio vortcbrto !« 
always scHoos is to s;K-ak verj- mildly. It were belter perhaps to say 
that tKiHuioaaily a case way recover. Fractures uf the IraDSVurse pro

Instead of stating the indication in this claas <ri* cases, as if assumiog 
tlioui (o be mcdteable, tho quoatiuu naturally bcoomes ratbcr a tiucry ; 
"Oiin any treatment be recommended in a fraclnre of the body of a 
Tertebra f" The only indiealiou in such a case, iu our opinion, is to 
ivacb the trnc diagnosis in the shortest possiblo tiniu and to act ac- 
cordingly. If there is displacement, and the existeuce of seriona le-

tlio Buflferiug animal api>ears to snggext itself x<4 the one conclusion in

With the exception of tlic deformity of the ilium in a fracture of Ui

sues and intiitration of Mood, or excessive disptacetnent, there are uo 
very dcfluito cxtetual symptoms lu a case ofa Iractutu of the hip trane. 
Tlieru IK one, however, which, in a majority of cases, wilt not fail — il: ii 
crepilation. Tins evidence l.s ottaimible by holb external and intt-ruul 
ex;uuiiiatiou — by manipulation of the gluteal surface and by rectal 
taxis. Very often a lateral motion, orbalaueing of the hinder iKirts hy 
pressing the body from one side to tbc other, will be snfntient to ren- 
der llio crepitation more distinct — a slight scusatiuu of grating, whJc 
niay ho pcrcclrcd eveu throngh the thick coating of muscle whi 
covers the bone — and the Kensalion may not only befell, but lu the 
of the expert may even become amlible. This exterual manifeiitati' 
is, however, not always suOicieut iu itM^lf, and fihould nlvraya be 
ciatetl with the rectal taxis for corroboratiou. it ia true that this ma 
fail to add to the evidence of fractuie, but till then the siaiplcleslluion 
aOVirdud by ihe detection of eri-pitation from the surface, though n 
fitroug conQriuatory point, is scarcely suQlcieally absolute to cslablijtb 
moro than a reasomtblo probability or strong suspicion in the case. 

In addiliou to the fiiet that the rectal exniniuntion brings the explopj 
log hand of the aiirgccu iuto near proximity to the desiretl imiot o^^ 
Bearch, and to au accurate knowlcdgeof thoaituatiou of parts, both j»ro 
aud con as respects bis own views, there is another advantage attend.-

By tbid Dietliod bo can batrdly fail to n!?^-ertaia the character of tbe 
ftnctnro and Ibo coDditlon of tbo bouy ends. By tbo rectal taxis, as if 
witli eyes in tbe finger ends, be will " see ^ vtXiat iB tbo extent of tbo 
fhictilrt: of tbo ilium or of tbo neck of tbat bono; to vrhat part of (be 
MDtral portion of tbo bone (the aeetabulnoa) it reaches; wbcther this 
is free from diRcn&o or not, and in xvbat location on the Uoor of tbo

ayinptODje and an citernal exatninatiou, could only bavc been guessed at 

Tet, u'itb nil its ndvautagcs, tbe rcctnl cxnuiinntiou is not uhvnya

Qxtema] uogle of tbo isebium, wbcn by fticliou of Ibc bouy ends tbo 
flargeou may discern tbo crepitation iritbout it. 

Every \ariely of com plication, inchiding uiusculnr lacerations with 
tbe fiirnialioii of deep abscesses and injuries to tbo organs of tbo pelvic 
cavity, tbe bladder, tbe rectum, and tbo ulcnis, may bo associated 
nilli fractures of tbebip bouc. 

Ibo prognosis of tlieso lesions will UGCCssnrily vaiy considcratdy. A 
fntcture of Ibc most superlicial part of tbe bone of tbo iliiiui or of tbo 
bcbiuui, especially wbeietbcro is little displacement, will uuilo rapidly, 
leaviug a comparatively sonud auiuial often quite free from subsequent 
bimcuess. Bnt if tbero isiuucbdidplaceuiei)t,onIy&ligaDientous union 
will tate place, with much deformity and mor«j or less irregularily in 
(be gnil. Other fraclui-cs may be folloncil by complete disability of 
Ibc patient, as, for example, vben tbo cotyloid cavity is involved, or 
vben tbe reparatory process bos tefl bony deposits in tbo pelvic cavity 
at tbe lieat of tbe union, trbich may, n-ilb the female, interfere with tbo 
Btc|)s of parturition, or iiidueo sonic local paralysis by pressure niwn

Tbu treatment of all fractnres of tbe hip bono sliould, in our estimik- 
tion, be of the simplest kind. Ecnderctl comparatively immovable by 
tlie tbiekuess of tbu musoles by which the region is euvelupiil, one es- 
sential indication suggestii itself, and tbat is, to place ibo auittial iu & 
poiutiou wbicb, us fur IIS {lossible, will bo Qxcd and peruinncut. For 
tbe accomplishment of this purpose tbe best measure, as wo consider it, 
is to pUinj him iu a stall of Just suflQcient width to admit liim, and to 
apply a set of filtngssongly, but comfortably. This will fulfill tbe cs^u>

Fracture of the scapvla.—Tlih bono is seldom fractured, iia conipar4>" 
live exemption being duo to its (tec mobility and the protection it re- 
ceives from the snperimposed soft tissues. Only direct and powt-r'al 
causes nro snfncicnt to e.ll'cct the injury, and when it occurs the larg* 
rather than the ttmatlcr animals are the subjects. The canaps ure beavj 
blows or kicks, and violent collisions with nnyieUIinc objects. TboMi 
which are oocajtioncd by falls are generally at the neck of tbe boDe,^ 
of the traiisrerso and coniminntetl varieties. 

The diagnosis is not always easy. The symptoms are Innbib'ty to! 
the leg on tht^ jfroniitl and to carry weights, and tbcy ate present ll 
rorions degrees from slight to severe. Tbe leg rests upon the toe ao^ 
seems shortened, and locomotion is performed by Jumps. Moving tb« 
leg while examining it and raising the foot for inspection seem to pro- 
duce m»ub pain and cause the animal to rear. Crepitation ia readily 
felt with tho band npon the shonider when the li^g Is moved. If the 
fraetura occurs (u tho upper i»art of tbe bone, overlapping of the frag- 
ments and displacement will 1>e considerable. fl 

The fracliiru of this bone is tisually ctasiiisl among tbe more iorioarH 
nocident-s, though cases may occnr'which are fotloived by recovery wlth.- 
oul very serious idLiinate results, especially when the scat of tho injair 
is at some of the npper angles of tbe bone, or about theucromioQcreat 
But if tho neck and tho joint are the parts involved, complicatiooa ant 
apt to bo present which arc likely to disable the animal for life. 

If thero is no displacement n simple adhesive drvKsiiig, to strengthen:] 
and immobilixo the purta, will be suBicicnt. A coat of black pitch dl 
aolveil with wnic and Venice turpentine, and kept in place ori-r th«^ 
region with oakom or linen bandy, will be all tho tre»tmcut required, 
eftpc«inlly if tho animal is kept <|uipt in the slings. 

Disidacement cannot be remedied, aud reduction is next to impO«>.

tlto nuliott or the cubitus, tiio llrst being broken at times in its upper 
portlou above tbe radio-cubital aruh at tbo oletirauou. If the fraclure 
occurs at any part of tbe forearm from the radio-cnbital arch down to 
the knee, it may involve eiilicr tht; radius alone or the radius and the 
cubitus, which arc there intimately united. 

Besides having the same etiology with moat of the Oactures, those of 
th» fortfarm are, nevertheless, more commouly due to kicks from other 
auim»U, vMpei^ially when crowdeil together in large numbers in inituffi- 
lucut space. It is a matter of observation that, under these circau-

tatieous, whilH those of the complete class are cither oblique or trans- 
verse. The least comoiou are the longitudinal, iu the long axis of the 
boue. 

This variety of fracture is easily rocngnizcd by the appearance of the 
Irg and ihu diQV-renL changes it undergucs. There is iuability to use

Fracture o/ the patella. — Tbis, fortanntely, is a rare accident and cikn

and ili»«iiHe of tbe articalation. The proguosiB is nunvoidnbly adverse, 
de^iruetlou being tbe only termiiiatioo of an incurable and very paio* 
ful injury- 

Fractures 0/ tke (Mia are probably more ftequenlly eticonnto 
tlinu liny otliera among the clans of accldeota we are considering. Ag 
with iujiities of tbe forearm of a like character, tbey may bo uuinplete 
or incomplete ; tlie former wlien the bono is broken in lbt« middle or at 
tbe extrt^inilictt, and trauttverau, oblique, or longitudinal. Tbo idcuiD' 
plete kind ore more common In Ibis bone than in any otbor. 

Complete fhictures are e.nsy to recognize, either with or without dhi- 
placement. The animal is very lame, and tlin leg is either dr.igy:eil or 
held np clear from the ground by flt-xiou at tbe stiQe, while tbe lowet 
part bangs down. Carrying weight ormoving iKtckwards is impoMi- 
ble. There is exoessive mobility below the fraclure and well-marked 
crepitation. If there is much displacement, aa in au ublitjae fracture, 
tburc will be ooiiKiib>riible Hborteuing of the leg. 

While incomplete fractures can not be recognized in tbe tibia wjtfa 
any greater degree uf certainty tban in any other bone, Uiero are scmm 
facts associated with them by wlncli adin<roo8is may be jusUDed. Tbe 
byprttbetical history of a case may serve an an illnstration: 

Au animal bos received au iQjui->' by a blow or a kick uu the inside of

Iniiiiediately afterwanls, be is allowed a few days' rest. Being then

The pmsuonis of friictitre of the tihia must, as a rule, be niifavornble. 
TheditHcnlty of obtaining a nnion without shortening and coDscquctitly 
without lamoiio&a, is proof of the futility ofunliriury »t1e»i|)tH at trput- 
inent. But though this may be true iu respect to fractures of the com- 
plete kind, it its nut lu^cti^arily mi with the inuomplute variety,and with 
this class the simple treatment of the sliogs is all that is ncci-Bsnry to 
set!uro cousolklatiou. A few weelcs of this coiiQuoincut will bu suffl.

With doga and other small animaU there arc casen whtoh may be 
snccessfully treated. If the neceiuiary dressings can be sQceessrully a[>-

FtactureM of the hock. — InjiirieH of the astragalus have twen reeorded 
which had a fata] tenuiuatiou. Fractures of the dk calciNhavralso been 
Obaerred, bat never with a favorable prognosis, and attempts to induce 
recovery have, as miRbt have been anticipated, prorcd fntile. 

Frartitret of the cannon hnntg. — Whether these occur in Iho fore or 
btiul legs they appear oitUer Iu thu body or near their cxtrt-milics. If 
in the bo<ly. as a rulo the three metacarpal or metatarsal are aim af- 
fected, and the fracture is generally transverse ond obliqne, nnd oneo 
eompimnd, one of thi> sef^mcntfi protruding Kliar]ily throngh the skin. 
Elaviiig uuly the skin fur a covering tbetltagnosU is easy. There in no 
displacement, bat excessive mobility, crepitation, inability to suslnfo 
weight, and the lofr ia kept off the ground by the flexion of the upper 
joint. 

Mo region of the body affonla better faailities for the appHcatton of 
treatment, and the prognosis is, on this account, usually favorable. 
We recall acuso, however, which proved fatal, though under exceptional 
clrcuniHtanceH. The patient vim a vahialite Htallioa of higlily nervous 
org^ini nation, witb a comiiound fracture of one of the cannon hones, and 
bit uncouquerablo rcRtstancii to treatment, excited by tbeinteiiNR pain 
of the wound, precluded all chance of recovery, and ultiiualely caused 
bis ileath from nervous fever. 

The general form of treatment for these lesions wilt not differ from 
that which has been already indicated for other fntctun-s. KciliicUon, 
6ometimc«t uocc«sitating the casting of the patteutj oouptttion, com- 
paratively easy by reason of the subcutaneous situation of the l>one; 
retention, by means of spllutA and banilages — applieil on both (tides of 
the n!gi(io, and reaching to the ground as in friictnresof tliefurearni— 
these are alwa:rs iuUicatcd. We havvobtaiuctl excellent n-snllK by the

From whatever cause this lesi<;j may arise, it can hardly be coiisid* 
erod oitof atraumatic nature, no exterual violence baring any apparent 
agency in producing it, and it ta our ttclief that it is due to a pccilHilf 
dc;;i-neratiuti nr Hoftcniut; of the bonus tliemsulvea, a theory which ac- 
quires plausibility frooi tbe coastderatiou of the ai)o:}gy consisteocv of 
the scaanioida. The disease ia a peculiar one, and the suddenucKa with 
vhicli dtlTurcot feet aro successively iittjiekeil, at Hfaort intervals and 
without any ubviom aiuse, seems to prnvc the exialencoofsoiuc latent 
morbid cause which has beuD unsaspectcdly iiiuubatiD;;. It is not pe- 
enllnr to any particniar ela^ of horses, nor to any special season of the 
year, having fallen under onr observation in eiujh of the four seasora. 
Thi* (•rnci-al fact is reported iu tbe hiatory of a majurily of ciise^ that it 
uakca its api>carance without premouillou in aaimala which, after en- 
joying a considerable period of rest, arc first exorcised or put to work, 
tbonghiu puiutof fact it may manifest ilxell' while the horse is still idle 
in hia stable. A. bypotlietical cose, in illnatratioD, will exphtin our 
tbeory : 

An animal which bus been a* rest in his stable is tjikeu oa^ to work 
and it witt bo presently noti(u^d that (bare is something uunsnal in his 
moreuient. His gait is changed, and he travels with abort, mincing 
Steps, without any of hU accustomed eaae and frceilom. Tbia may coa< 
tiuue until his n^tnpii to tJie stable, and then, after being placed in his 
stall, be will bo noticed shil'ling hiit weight froiu side to sidi* and from 
ouo lug to another, continuing the movement until rupture of the bony 
etructure takes place. But it may happen that the lamcuenti lu one or 
luorc of the exLremitica, anterior or posterior, HuddtMiIy increiueH, and it 
becomes evident that tbe ruptui-e has taken place in consequence of a 
mJTt^stop or a atainble while the lior»e is at work. Then, upon coming to 
a atan<lstdl, he will be found with one or more of his toca turuwl up— ho 
iti unable to plaoo the nflVeted foot flat on the ground. The fetloi-k has 
tlroppctl tmd the leg leuts upon this part, the skin of wUicli may have

ami wo recall one case in wfaicli tlie tvo fore nut) one of the bind li-|;a,

likeljr to liappeii while the honw is »t rost in his stiill, aad lie may 
found iu the luorniug standing on his fetlocks. One of (be earlicxt

uovoral wocbrt for aii.-i[)ccted (li*!«H<! of llio fetlocks, the uatnre of wbieh 
bod not been made out, when, n))parent|y itaproTcd by tho troatmcfit 
wliiL'ti he lifid nnderjjone, the patient was luken out of the Htnltle tn Ito 
wnlUi'd a short di^ance into the conntry^bnt h;id little more than start* d 
vheu ho was called to a bait by the fnicture of the tiesauioids of both 
fore le^s. 

While there are no positive premonitory symptoms known of tbew 
frnctnres we beliere that there are signs and symptoms which come 
biib little short of beiug so, and the »pi»oaranoe of whteh will always 
justify a strons suspicion of the truth of the caso. These have bi-eD 
Indicated when referring to the soreness iu standing, the short ^ mtao. 
lug** gait, and the tenderness betrayed when pressure is made orer the 
scetamoids on the sides of the fetlock, with others lesa tangible and 
delbmble. 

These injuries can never be aeeoanted lesa tb»a serious, and in oof 
f adjfmeut will never be other than fatal. If our theory of tbetr pathol* 
ogy is the correct one, and the canso of the lesions is tnily the soften- 
ing of tho sosamoidal l>ony stracture and indeiK^ndent of uny chaogea 
in tbo ligamentous tiber», the possibility of a solid o^seaus untoa caa 
h;inlly beconsiderod admiaslble. 

Iu respect to the treataiont to be recommendal and instituted It con 
only bo employed with any rational hope of benefit during the incnltt' 
tioii, and with tho anlicipntory purpose of prevention. It mast tje tag' 
gODtiHl by a suspicion of the I'eritieH of the case, and applied Itcfore a^y

bjLudugca or spliuttt, perhaps of plaster of Paris, with a high shoe, as 
about tho only indications which science and iiatnre are able lo offt-r. 
When the fnicturo la an occurred ercut, and the toes, uiie or more, am

of nlceraiirc arthritis, one of the gravest among all the ilisorders kiw« 
to the nnimat economy. 

Rot ulcerative arthritis and suppurative synovitis may Iw developeJ 
in other connections than ihat with open joints ; the simplest and ap> 
pareiitly most hiirniless pnnettires may prove to be cause sufflcicnt. 
Por example, n liorso may be kicked, perhaps, on the inside of tbs 
bock ; there is a mark and a fen* drops of blood to indlcatu the spot; 
he is put to work, apparently free from pnin or lamenep.';, and p«- 
forms his task wiih his usual ease and facility. But on the fulloiriD; 
Dioriiiaf; the hock is foniid to lie a little swollen and there in some stiff- 
iiesin. A liltle later on he betrays a degree of uneasiness in the lo^, and 
shrinks (him resting his weight upon it, uioviu^^ it up and dunn for 
relief. The swelling has increased and isincreasing; thepain is severe, 
and, finally, there is an oozing at the spot where the kick impinged of 
an oily li(]uid mixe^I with whitish dro])s of suppuration. The mischief 
is done and a simple, harmless punctured wound has expanded into ft 
case of ulcerative urthritlH and supimrative Kyiiovitis. 

From ever so brief and succinct description of this traumatism of the 
arlieulationa, the serious and biiportaut character of these lesions, irre- 
spective of which particalar joint is affected, will be readily nndcrstood. 
Yet there will l>e inotliQcations in the prognosis In d'Hercnt cases, io 
accordance with the pecaliarities of structure in the joint specially 
involved, as for example, it is obvious that a hotter resnli mny be ex- 
pected from treatment when but a single joint, with only its plain artio* 
uhir surfaces is the place of injury, than iu one whicli is comiwsed of 
several bones, ntiitod in a compl<Jx formation, as in the ko«o or hock. 
As severe a lesion ns snppnmtivo synovitis always is, and lui frequently 
fatal as tt proves to be. still cases ariso iu which the iuUammatloa, as- 
suuiiug a modified character and at length sabaidiog, the leaioa tvrmi-

cori'rj- and diagno><i.s. 

For simple brui&es, like those wbieb appear in tho form of broken 
kiMemor of cArpitiSf 6iiii[>te remediejs, uuch as vrarm fomoiitatioiui or 
cold water applicatione and compresses of astringent mixtures, suggest 
thMuselrus at ouue. Injuries of a more compllcntcd cIiAraeler, nslacer- 
■lions of the skin or tearing of soft strnctnre-s, vrill also be benefited by 
simple dre:^sin!:.s with antiseptic iaixtiiies,ns those of tho carbolic acid 
order. The escape of synovia should suggest the prompt use of collodion 
ilressiiigs toclieek the dotr and prevent the further cscapeof the lUiid. 
But if the dischurgt; is abundant and lieiivily suppurative, tittle can be 
done more than to put iu practice the "exiiectant" method irith narm 
fomentations, repeatedly applied, and soothing mucilaginous poulticea. 
Improvement, if any is possible, nill bcbutsloiv tonniutfeJil itself. The 
most difQcuU of all things to do, in view of varying Interests and opin- 
ions—that is, ill a practical sense — is tonbstain from "doing" entirely, 
and yet «•« are firmly couviocod thai uou Jutcrfcrucc, in the ciisea we 
are considering, is the best and wisest policy. 

In cases which are carried to a successful result the discharge wH? by 
degrees dtmiuish, the extreme pain will gradually subside and iJie con- 
valewcut Till begin timidly to rest bis foot npon the ground, and pres- 
ently to bear weight uiion it, and perhaps, after n long and tetlions 
processof recnporatlou, he may bo returned to his former and normal 
condition of nsef'ubiess. When the discharge has wholly ceased and the 
vonnds arc entirely healed, a blister oovorlug tho whole of the joiot for 
the purpose of stimulating the absorption of the exudation will be of 
great service. But if, on the contrary^ iheraisno amcl ioration of symp- 
toms nud the progress of tlie disease resists every attempt to chi^ck it; 
if the discharge continues to How, not ouly without ttb.itement, bnt in 
an increased volume, and nolulnueby usinglo opening but by a number 
of flstnlous tracts which have successively formed ; if it seems evident 
tliat this drainage is rapidly nnd painfully sapping the sntTcriag animal's 
vitality, and a doQcient fir tito! fails to cooperate with the means of 
cure, oil rational hope of recovery may be Sually ubciudoucd. Any far-

DISEASES OP atUSOLES AND TENDONS. 

Sprains.-^Thls ti-rm expresses a more or less complete laceration or 
yielding of the fibers of the muscles, tendons, or the sheaths surround- 
ing and supporting them. The usual cause of a sprain is external vio- 
teoce, such as a fall or a powerful exertion of strength, with following 
syniptonis of sorcuess, heat, Hnelling, uud a Kusi>ensiou of fuuction. 
Tlieir tcruiuatiuu varies from simple resolution to suppuration, and 
commonly plastic exudation difficuli to remox'e. Nouo of the muscles 
or tendons of the bo«ly are exempt from liability to this lesion, though

tbo one without which the poNsihib'ty of relapse will iilways rotnalii tu

aprain o/ the elboic lamclet. — Tbls iojury, which fortunately fs not 
very conimou, is mostly encountered in ciliv», among heavy draught 
horses or rapidly driven auitnals which are obligeil to travel, often 
smooth shod, upon slippery, icy, or greasy pavements, where ttiey ara 
easily liable to lose their foothold. Tbe region of the strain is the pos- 
terior part of the shoulder, aud tho muscles which are affected are those 
which occupy tbo space between tlie posterior bonier of the scapcda 
aud the posterior fuco of the arm. It is tho mascles of the olecranon 
whicli give way. 

The symptoms aro easily recogniKcd, especially when tbe animal is 
iu action. 'White at rest the attitude mny be normal, or by closoacm- 
thiy a iwculiarity may perhaps be delected. The leg may seem to drop; 
tbe cllww may appear to be lower tbna its fellow, with tho knc« and 
lower part of the leg flexed and tho foot resting on the toe, wiih tho 
beet raised. Bnch an attitude, however, may be occasionally assumt-d 
by an animal witboat having any spciual sigDiGcaiice. But when it bo- 
comes more pronounced on pnitiiig bim in uiottuii the fact acq aires* 
Bymptoui-ttic value, and this is the casoui tho present tustauce. A 



id gait becomes qnite imiiossible, and tlio valk ns in some feir otiier 
di34.''UJte.i becomes suflicicDtly characteristic to narraut a dlaguoais even 
wUen observed From a distance. An entire dropping of tlie anterior 
part of tlio iruuk becomes mnnifest, and uo weight is carried on the 
disabled Ktde, iii eonscqtience of the loiss of notion ia the Hnspen»tor]' 
muscles. Tltcri> are often beat, paio, and sn-eltiog in the muscular mass 
at the elbotr, Iboiigli at times a hollow or depression may bo observed 
iMT tbo posterior border of the scapula, wbich is probably tbo scat of 
iiyur}-. 

These hurts are of various degrees of importance, varying from mere 
minor casualties of ijuick recovery to lesions which iiro of 8uflici«ut sc- 
Tcrity to rcDdcr an aoimal nsclcss and valueless for life. 

The prime elemental of treatment, which HhoiiUl be strictly observed, 
arc rest and quiets. Prcscriplioiis of »11 kinds, however, of course, have 
tliL'ir adrotuttrs. Among theni arc ether, chlorororm, camphor, iilco- 

Iholic frictions, warm fomcatatioos, blisters, sctoos, etc. Bat, unless the

The prognosis of bip lameness is at times fiaito Korlous, uul nni, 
oo account of the long duration of treatment retiuired to effect- g
