As in ‘‘Special Veterinary Therapy’’ no particular system of medicine is advocated, practical procedures only being given attention; especially, such treatments and methods of handling as the author’s experience has suggested as being successful. While every effort has been made to harmonize all procedures with the teachings of veterinary science as far as is consistent, scientific teachings have been sac- rificed where the ultimate result has demanded methods of treatment bordering on the empirical. Where such sacrifice has been made, however, an attempt is made in every instance to explain the action and effect of empirical methods on a scientific basis. MART R. STEFFEN. Brillion, Wis.

The EXCELLENCE OF EVERY) ART MUST CORSIST IW THE COMPLETE ACCOMPLISHMEWT OF 175 PURPOSE INTRODUCTION The Action of Drugs Of all the domestic animals cattle, more particularly dairy cattle, respond most satisfactorily to the action of drugs. A system of specific medication is possible in cattle if it is possible in any animal. Granted that the drug has been intelligently selected for the disease, and that it has been judiciously administered, a defi- nite action is always forthcoming. This is true whether the drug be given orally or hypodermieally, but espe- cially so when given orally. The Administration of Drugs For all practical purposes the administration of drugs can be limited to oral and hypodermic adminis- tration. Oral administration in the cow is a very simple pro- cedure, especially so when the cow is not confined in a stanchion. The thumb and forefinger of the left hand grasp the nasal septum firmly from above and just inside the nostrils. The head is then raised straight up, under the veterinarian’s left arm, and the medi- cine emptied into the mouth. Most cows will swallow liquids in this manner just as fast as they are poured in. Usually the veterinarian can do this single-handed ; now and then a head-strong cow will require that a helper give the veterinarian some assistance in keep- ing the animal’s head raised. There is an impression among farmers that the tongue must be held out of 5 6 SPECIAL CATTLE THERAPY one corner of the cow’s mouth when the animal is being drenched. This is erroneous. The tongue should not be touched by the person giving the-drench. The free use of the tongue is necessary to properly per- ’ form the act of deglutition. The mouth of the bottle used for drenching should rest against the roof of the cow’s mouth, just back of the dental pad, and should then follow the movements of the tongue, up and down. In other words, each time the cow swallows the mouth opens wider and the tongue is drawn back towards the pharynx; the bottle should follow in, keeping it against the roof of the mouth and until the shoulder of the bottle strikes the first molar. When the act of deglutition is completed the tongue comes forward again and the mouth closes; the bottle is then allowed to come forward again towards the region just back of the dental pad. This is repeated at each deglutitory act until the medicine has been entirely poured in. When eattle are drenched in this manner the danger of inhalation pneumonia from portions of the medica- ment entering the larynx are nil. To jam the bottle into the corner of the cow’s mouth when drenching and hold it there until it is empty is not the correct method and usually induces a fit of coughing immediately after the drench. The hypodermatic administration of drugs does not differ materially in cows from the same procedure in horses. It is only necessary to use a heavier needle and to select a place in the skin where it can be in- serted easily. The top of the shoulder presents a good area for the entrance of the hypodermic needle in cows. The skin is loose enough here so that a fold can be picked up, and it is not so tough here as in other parts. Another point in selecting this region lies in the fact that the veterinarian can get into such INTRODUCTION il a position here that he can avoid being kicked by the cow when the néedle is thrust in. The needle should be thrust from above downwards, and a slip needle should be used if possible. ii: needle with a screw thread is used it is frequently broken if it is thrust in while attached to the syringe. If it is not attached to the syringe, too much time 1s lost in attaching the syringe after the needle is im situ. When the cow is recumbent the injection can be eiven in the side of the neck, or in the region of the flank. Abscess formations following on hypodermatic injec- tions in cattle are almost never seen, even when no antiseptic precautions are taken, Things that Make for Success in Cattle Practice In beginning the discussion of diseases of cattle it might be in place to eall the reader’s attention to the fact that it would be a difficult matter to cite author- itative and, at the same time, practical writings on a system of therapeutics for cattle. Bovine therapy 1S a specialty of veterinary medicine which offers a con- siderable field for the development of improved and enlightened methods of treatment. The same is true of the diagnosis of diseases of cattle. Another point worthy of consideration in eattle prac- tice is the veterinarian’s personality, or his demeanor towards the patient. This can almost be summed up in two words: ‘‘Be gentle.’? Weare speaking, of course, of dairy cattle. No consideration is given to range cattle in this treatise. The diseases with which we shall concern ourselves in the following chapters include the pathologie con- ditions and accidents in cattle with which the prac- 8 SPECIAL CATTLE THERAPY titioner most frequently meets, and especially those conditions upon the proper and efficient handling of which depend the veterinarian’s popularity and his financial success in a country practice. RANULA There does not ‘seem to be much conformity of opinion among veterinarians as to just what a ranula is. For the present purpose we shall call a ranula a cyst which makes its appearance under the tongue, extending from the frenum lngue forward, towards the incisors. It is quite generally presumed, that this condition is the result of foreign particles entering into the substance of the submaxillary gland through Wharton’s duct. The symptoms in this condition usually begin with the appearance of fullness or swelling which ean be seen best by viewing the cow’s head from the side. It begins two or three inches behind the chin in the inter-maxillary space, is pouch-like and extends back- ward towards the larynx. This swelling is movable and ean be pushed upwards between the rami of the lower jaw, free from the skin. (The swelling of acti- nomyeosis affecting this region is adherent. ) After a period of time the cow does not eat nor- mally and saliva constantly drips from the mouth. Usually it is at about this time that the veterinarian is called. When, after having noted the external swelling, he examines the interior of the mouth he discovers a swelling below the free portion of the tongue. This swelling usually is circumscribed, stand- ing out from the parts to the height of an inch or two and, in the early stages, is quite firm. The fact RANULA 9 that the swelling is circumscribed sharply, differen- tiates ranula from all other abnormalities in this part of the anatomy, and it can not be mistaken for any other disease. The treatment is chiefly surgical and consists of lancing the swelling in the mouth at the point proximal to the incisors. A straight abscess knife is merely thrust into the front of the swelling and withdrawn; no extensive incision need be made. If the disease is of recent occurrence the discharge which is emitted following the lanee is quite thick and of a dark gray color; in fact, more of the appearance and consistency of necrotic tissue shreds than of pus. If the disease has existed for a considerable length of time the swell- ing, which is then not so firm, contains a rather thin, syrupy fluid. Nothing further is done to the lesion im the mouth, but the external swelling is to be treated with a mild counter-irritant or an absorbent. Relief is immediate when the cyst has been laneed and the cow begins to eat normally. The essential feature in the handling of this condition lies in lancing the swelling in the mouth. The external swelling should never be incised. Further, no time should be wasted in waiting for the internal swelling to ‘‘point’’; it should be laneed even if it is apparently ‘“‘not ready’”’ to be lanced. Whenever ranula has reached the stage in which it produces trouble in eating it is ready for opening, no matter how firm it may feel. The knife should penetrate to the center with one thrust; upon its withdrawal the contents of the cyst makes its exit. 10 SPECIAL CATTLE THERAPY DENTAL IRREGULARITIES AND OTHER SPO- RADIC DISEASED CONDITIONS IN THE MOUTH Dental Irregularities Irregularities of the teeth do not come to the atten- tion of the veterinarian frequently in a cattle practice. When such irregularities do occur they are usually so evident by their symptoms that the diagnosis is not difficult. Probably the most common dental irregularity that occurs in the cow is the split and deflected molar; such molars are, in fact more common than is generally sup- posed. Systematic examination of the mouth and the dental arches will disclose this abnormality quite fre- quently. It is, however, astonishing to what length a split and deflected molar can grow in cattle without inter- fering to any great degree with mastication or the well- being of the animal. We have seen only a very few cases of ulceration of teeth accompanied by bony en- largements and subsequent abscess formation on the maxilla. Now and then a ease is presented in which deciduous molars are capping the permanent teeth, producing a certain degree of difficulty in mastication. This con- dition is very rare also. The treatment of dental abnormalities in the cow does not differ materially from the treatment of simi- lar conditions in equine subjects. Split and elongated molars are either extracted or cut down with the molar cutter. Uleerated fangs are repulsed if they can not be grasped with the extracting forceps. DENTAL IRREGULARITIES _ 11 No manipulations of any extent should ever be at- tempted in the mouth of the cow without the use of a strong mouth speculum. Those not acquainted with the contractile power of the masseters of the cow should not chance experience to make this acquaint- ance. The power of the masseters in the cow is tre- mendous; aided by the scissor-like movements, of which the mandible is capable in this animal, it makes manipulations in the cavity without the use of a good mouth speculum far from a safe procedure. A per- fectly trustworthy speculum can be made from an or- dinary plow clevis, when no other speculum is at hand. We have used a plow clevis for this purpose a number of times and with satisfaction. Care must be observed to keep it in an upright position, in case the cow moves the head suddenly. Stomatitis From Mis-Cut Ensilage Ensilage improperly cut in length is frequently the cause of a considerable degree of stomatitis and ulcer- ations of the buccal mucosa. The condition makes itself known by profuse sali- vation, smacking of the lips, and refusal of feed. All the symptoms point to a purely local trouble in the mouth. Several cattle are usually affected simultane- ously. Examination will show the mucous membrane of the mouth quite generally inflamed, with numbers of spots in various stages of ulceration. We recall an instance during the recent epizootic of foot-and-mouth disease in which a city veterinarian diagnosed this condition, caused by mis-cut ensilage, foot-and-mouth disease. A small-town country prac- titioner promptly set him right and handled the cases to the satisfaction of all concerned by withdrawing the ensilage from the daily ration. 12 SPECIAL CATTLE THERAPY This, in fact, practically constitutes the entire treat- ment of this condition. Should a particular case pre- sent especially severe lesions a mouth wash ean be used for a few days, or the ulcerating spots can be touched up with equal parts tincture iodin and com- pound tineture of benzoin a few times. Foreign Bodies in the Tongue Hard, sharp objects such as pins, nails, pieces of wire and the like, are quite frequently found lodged in the. tongue of the cow. We dare say, that in probably ninety-five per cent of the eases absolutely no symp- toms are produced that can be observed ordinarily. When symptoms of an objective nature are produced they point very distinctly to the region involved. Objects which are not wholly embedded in the lingual tissues may be discovered without difficulty. They are to be removed and the wound given whatever atten- tion is required. Very small wounds here are best left alone. Objeets which are wholly embedded are detected by very eareful and painstaking examination, disclosing their location always as a distinetly circumseribed area of hardened tissue. When this area has been located it is still necessary to locate the object itself by in- cision, carrying the incision inward by repeated cuts until the object is disclosed. It is then to be appro- priately removed and the wound is treated along ordi- nary lines. ACUTE PAROTITIS 13 ACUTE PAROTITIS Acute inflammation of the parotid glands, commonly termed ‘‘mumps,’’ is a very common disease of cattle. It is seen under all conditions of housing and at va- riable seasons. The prognosis of parotitis in cattle, (not due to actinomyecosis), is very favorable and the course of the disease is usually typieal. Parotitis begins with a rigor in most cases. The temperature may run as high as 106° F. in the be- ginning. At the same time there is noticed a slight fullness in the region of the parotid gland, from the ear to the angle of the jaw. This fullness increases rapidly until at the end of twenty-four hours or there- about, there is a distinet, rounded swelling in the re- gion. This swelling is very tender on pressure, and the cow stands with the head extended in a line with the neck. If the trouble is unilateral the head is held to one side and partly twisted on its own axis. The cow attempts to eat but finds deglutition very pain- ful, and usually all feed is refused. In drinking water much time is consumed in the act and, after a number of swallows have been taken, the animal gives up the attempt. If the swelling in the parotid region is very extensive and reaches below the larynx and between the rami of the lower jaw there may be a degree of dyspnea. Ordinary cases yield to treatment in a week or ten days. In other cases abscess formation delays the recovery, so that in certain instances three or four weeks may elapse before the case is completely cured. The best results in the treatment of this disease are obtained from repeated injections of polyvalent bac- terins. We give a full dose hypodermically every three days until the case is under control. 14 SPECIAL CATTLE THERAPY For local applications over the swollen parotids we have found nothing better than iodin tincture. The first two or three days we paint the entire swelling Several times during the day with pure tincture of iodin. Later we make the applications only onee daily. Since we have been using the foregoing treatment we have had no case with abscess formation, and re- covery iS more prompt than with old line treatments. In addition to the above treatment we make it a rule to see to it that a tub or large pail of water is kept constantly before the animal where it can be reached without much effort. A few tablespoonfuls of dilute sulphurie acid are added to each tub of water, for its refrigerant and astringent effect. The feed should consist of thin slops and other moist feeds. If abscess formation should occur we recommend early incision. We do not pay much attention to the invasion of the parotid gland with the lance; even when the abscess is lanced directly through the gland substance. Permanent salivary fistula is rare. ACTINOMYCOSIS (‘‘Lumpy Jaw’’) Actinomycosis comes to the veterinarian’s attention only when it is localized on some exterior portion of the body. Actinomycotic processes of the internal or- evans, such as the lungs for instance, are probably never diagnosed ante-mortem. The actinomycotie lesion most frequently seen in practice is in the region of the angle of the lower jaw or in the parotid region. Next in frequency as regards location is that form which involves the tissues lying in the space between the rami of the lower jaw. ACTINOMYCOSIS 15 Not quite so frequent, but yet common enough, is actinomyeosis of the tongue. In all forms this disease shows a decided preference for young or middle-aged cattle; old cattle are only occasionally affected. While it is presumed to be infectious it is generally found in isolated instances. One cow in a herd of dairy cattle may have the disease in a well-marked form and not another animal in the herd become affected; but often more than one become affected, the number sometimes including twenty-five per cent of large herds. : When the disease makes its appearance at the angle of the jaw it is in the form of a smooth tumefaction or lump, or ‘‘bunch.’’ In the early stages this tume- faction increases in size, becomes more firm, and usually tends to become anchored or fixed to the bone. Still later the center becomes necrotic, and the typical stringy, marrow-colored pus is discharged. If the case is not checked at this time it may pro- gress until the bone itself is involved in the disease process, and the treatment then becomes difficult. When actinomyeosis involves the tissues lying be- tween the rami of the inferior maxilla we find this space completely filled with a mass of dense, appar- ently fibrous, tissue. If the disease has existed here for some time the enlargement can be seen plainly with the animal in the standing position; the under side of the jaws between the chin and throat appears curved from before backwards with a considerable belly towards the bottom. After variable periods of time this swelling breaks down in one or more places. Usually there are three or four openings, and from these escapes actinomycotic pus. The pus in this location is not so characteristic, being thin and lighter in consistency. 16 SPECTALVCAT TRE TELA y Actinomyeosis involving the tongue usually does not produce noticeable symptoms until it is quite exten- sive. When the condition does attract attention it is usually seen that the cow has difficulty in mastieating her food. The mouth is constantly held partly open and saliva is continually dripping from the opening. The tongue seems too large for the mouth and when the veterinarian examines it he finds that it feels me + or less solid or ‘‘woody.’’ When the disease has p: oressed to this stage it is only a matter of a she t time until the cow finds eating an impossibility and if the condition is not properly treated the animal dies of inanition. The treatment of actinomycosis 1s very satisfactory when the disease has confined itself to soft tissue. When it has invaded the dense tissues, bone or ¢ar- tilage, the treatment-is not so satisfactory. In that form which asserts itself in the form of a tumor or bunch at or near the angle of the jaw t.1e treatment begins with incision of the tumor. That this may be safely and thoroughly done it is necessary to east the patient. It is almost impossible to so ecn- fine a cow in the standing position that the necessa *y steps in the treatment can be satisfactorily and safely performed. Having east the patient, the veterinarian incises the tumor near the most dependent part, using an abscess knife and making the incision not more than one inch in length. The incision is carried wll into the center of the tumor and the interior is then thoroughly curetted. This is a painful operation aid is best performed under anesthetics. When this has been done a gauze or cotton wad, which has been s,t- urated in a ten per cent solution of chromium triox d, is packed firmly into the cavity and the animal is allowed to get up. ACTINOMYCOSIS dO In most eases this completes the local treatment in this form of the disease. After a week or ten days the entire mass of diseased tissue drops out and leaves but little sear. The internal treatment in this, as in all other forms of actinomycosis, eonsists of the administration of oa iodid. The result obtained from the use otf —?*">tassium iodid in this disease is frequently nothing ‘hort of marvelous. The dose is from one to two “Gams three times daily for matured cows, and it 1s to be persisted in until all symptoms of the disease have disappeared. If iodism supervenes the drug can be discontinued for a few days and then be given again. Unless the disease has already involved the inferior maxilla a complete recovery may be expected in from two to three weeks. The treatment of that form which attacks the tissue lying between the rami of the inferior maxilla varies {rom the foregoing only in the local treatment. The openings which are present, if any, are merely en- larged slightly with a sharp curette. If there are no cpenings present no attempt is made to produce any Ly surgical means. The swelling is subjected to no further local handling than a daily painting with pure tineture of iodin. In actinomycosis of the tongue the treatment is con- fined to the internal administration of the potassium iodid. The results in this form are most prompt and highly pleasing to both the client and the veterinarian. lfowever, unless the treatment 1s persisted in for a sufficient length of time relapses of this form fre- cuently occur. The treatment should be kept up until iodism has been produced at least three or four times; only then can a cure be assured. Half dram doses of ~ 18 SPECIAL CATTLE THERAPY fluid extract of phytolacea improve the action of potas- sium iodid when given with it in these eases. In summing up the treatment of actinomycosis it ean be said that even very extensive lesions ean be controlled and ultimately entirely cured with judicious use of potassium iodid. In our own practice we do not pay very much attention to the local handling even when the actinomycotic growth has assumed great proportions. The following case report is an example of the effect of potassium iodid in this disease. A Jersey cow had an actinomycotic tumor at the angle of the jaw extending to and involving the parotid region. It was of long standing when it came into our hands, having gone through various courses of treatment with home remedies. At the time we were called in the cow was barely able to breathe, the tumor having involved the trachea and larynx, probably producing the dyspnea by pressure. The dyspnea was so distressing that a tracheotomy had to be performed. Under treatment improve- ment progressed so rapidly that the tube was taken out at the end of a week, all signs of dyspnea having disappeared. The tumor itself had been reduced to the size of a lemon. Another ease, illustrating the effect of potassium iodid in actinomycosis involving the tissues in the space between the rami of the lower jaw may be cited. This case occurred in a Holstein ealf, six or eight months old. The entire space was filled up with the growth and a number of openings were discharging typical pus. Examination of the interior of the mouth showed the lingual canal pushed up and nearly filled in, making the tongue appear as though it were crowded against the roof of the mouth. The calf was emaciated and stunted in growth. The openings were curetted slightly and the calf allowed to get up. He was put on a dram of potassium iodid morning and evening, and the enlargement painted once or twice daily with tincture iodin. In two weeks there was no sign of swelling and the calf had improved remarkably in condition. To assure a permanent result the potassium iodid was con- tinued a week longer and paintings were made occasionally with iodin. The calf has developed into a fine bull, is now eighteen months old and is entirely free from any sign of the trouble. The entire treatment covered about three or four weeks’ time. It should be mentioned that actinomyecosis involving the parotid gland is for some reason more difficult to EPIZOOTIC KERATITIS 19 cure than when it involves other soft structures, even more stubborn to-treat than some of the cases where osseous tissue is extensively involved. The treatment ig the same as that for involvement of other organs and tissues. EPIZOOTIC KERATITIS This is a disease affecting the eyes of cattle which occurs from time to time in certain localities. Tf-i8 seen usually during the summer months when the cat- tle are on grass. Almost without exception it attacks every animal in a herd of cattle which it invades. In rare instances a few animals may escape the infection. The first attacked in an outbreak usually develop the disease in its most severe form; towards the latter part of the epizootic the cases become milder and may recover spontaneously. The disease affects cattle only. Horses in the same pastures with the affected cattle do not develop the disease, nor are other animals on the farm affected. We recall an instance where a man, who had a herd of cows under his eare during an outbreak of keratitis and who treated the eyes of those affected, contracted a mild conjunctivitis. In the mild or sub-acute form the symptoms are con- fined wholly to the eyes. In the severe form the ani- mal shows systemic derangement such as loss of appe- tite and a considerable interference with the lacteal secretion. The first symptom, that the farmer Sees, when the disease appears in his herd is lachrymation. When the cows are brought in from pasture at night he notices a few cows with ‘‘a running from the eyes. bine 20 SPECIAL CATTLE THERAPY eyes are only partly open and the lids appear slightly swollen. Within twenty-four to forty-eight hours nearly every animal in the herd is affected. In those that develop the disease in its severe form the lachry- mal flow becomes purulent on about the second day. The cornea becomes the seat of an uleer, or several of them. In not a few eases the ulceration continues until perforation of the cornea results, staphylomata appear and the eye is permanently injured. A deposit of pus may also be seen along the inferior margin of © the cornea in the anterior chamber. Permanent cor- neal and even lenticular opacities frequently destroy the sight. In the mild cases the symptoms consist of profuse lachrymation, and a considerable degree of photo- phobia. This disappears in three or four days under treatment, or even without treatment. In the severe form from two to three weeks may elapse before the disease runs its course, leaving one or both eyes partly or wholly blind. The treatment of this disease is entirely local, con- sisting of antiseptic and astringent solutions and. oint- ments. In the mild form we use one per cent yellow oxid of mercury ointment. A small lump of this ointment of about the size of a pea, is placed within the lower eyelid near the external canthus and the lids pressed together a few moments, until the ointment becomes warm. It is then distributed over the interior surface of the orbit by gentle massaging of the lids and the movements of the eye-ball. The animals should be kept indoors and the stable darkened for a few days. In three to five days re- covery is complete. In the severe form, in which the discharges from the eyes are purulent in character a EPIZOOTIC KERATITIS 21 solution of zine sulphate of from two to four per cent strength is to be used. It is best applied with a small olass syringe having a soft rubber tip. With the owner or an attendant holding the cow’s head, the person giving the treatment draws the lower eye-lid away from the globe, by pulling on the lashes; about a teaspoonful of the zine sulphate solution is then squirted into the cup thus formed and the lid allowed to return to position. This is repeated three times daily until the most acute symptoms have dis- appeared. The treatment is then terminated, with daily applications of the yellow oxid of mercury oint- ment. In complicated cases that develop ulcers on the cornea the ulcers should be touched up every other day with ten per cent siiver nitrate solution, by means of a cotton swab on an applicator. Staphylomata that occur in the form of sacculated protrusions of the iris following perforation of the cornea from ulcer- ation, should be snipped off with scissors and then eauterized. Before either the cauterization of an ulcer or the ablation of the staphyloma is attempted the eye should be anesthetized. The simplest and most con- venient method of anesthetizing the eye is by placing a one grain quinin-urea hydrochlorid tablet between the lids, and waiting about twenty minutes for anes- thesia to become established. Collections of pus in the lower part of the anterior chamber of the eye are best ignored. They usually become absorbed without producing particular damage. Opacities of either the cornea or the lens that remain after the inflammation are best treated with iodides ~ internally. Synechia (adhesions between the iris and cornea anteriorly, or the iris and lens posteriorly) can usually be prevented by the addition of a few drops of fluid 22 SPECIAL CATTOR THhiar ¥ extract of belladonna (or a solution of atropin) to the zine sulphate solution. This will produce mydriasis sufficiently to withdraw the iris from the active field of the disease. Darkened quarters are essential in all cases, because of the marked photophobia. The affected cattle should be kept out of bright light until recovery is assured. Light should be excluded from the stable by means of blankets or canvas hung before windows and doors. Bandages should not be used with the object of shield- ing or protecting the eye. Their use favors ulceration. CANCER OF THE EYE This condition, sometimes termed fungus hema- toids, is decidedly common in eattle. Only one eye ° is affected as a rule, and the condition comes to the attention of the veterinarian in various stages, from the benign appearing granular growth on the edge of the cornea to the immense eauliflower-like growth in- volving the entire orbit. Most of these cases begin as a small, flat mass of eranular tissue near the corneo-scleratic margin. The mass stands off from the globe quite prominently and has the appearance of what is commonly termed ‘‘proud flesh.’? This slowly spreads over the surface of the eye-ball; in most cases, at first, in a thin, flat layer. Later, there is a purulent flow of mucus from the affected eye, and the growth begins to assume the form of a ‘‘bunch,’’ layer after layer of new cells be- ing formed. This continues until the growth projects outward an inch or more. The tissue is very vascular ; sight handling or touching in any manner induces bleeding. Still later the external surface of the mass CANCER OF THE EYE 23 becomes necrotic, assumes a blackish-gray color and constantly exudes serum, pus and shreds of tissue. If the disease is not checked the growth continues to increase in size, crowding the eye-ball deep into the orbit. Nothing of the eye itself can be seen; the entire orbital cavity is filled with the new growth, the lids and orbital conjunctiva developing additional new erowths. Finally the lymphatics in the region break down, forming enlargements on the side of the head and parotid region that open and discharge purulent mat- ter. The animal becomes ecachectic and finally dies. Treatment of cancer of the eye is not very satis- factory. If the eye is to be saved the case must be submitted to treatment as soon as possible after the first layer of granular tissue forms. If the veterinarian is able to begin the treatment in this stage he can promise his client fairly good results. To handle the condition satisfactorily, even at this stage, it is usually necessary to cast the cow and pro- duce profound anesthesia, without which all attempts at worthy treatment are usually converted into bungle- some interference. We make this statement with due consideration, following personal experience. When the cow has been chloroformed the orbital cavity is to be copiously irrigated with a very mild bichlorid or chinosol solution. With an eye speculum holding the lds apart the layer of cells is very care- fully shaved off, care being taken not to injure the healthy face of the cornea. In this early stage it will be seen that the layer of eranulation tissue is underlaid with a thin band of white connective tissue. This band is apparently the foundation of the growth; it is very intimately con- nected to the surface of the cornea. When the soft ~ 24 SPECIAL CATTLE THERAPY layer of granular cells has been thoroughly shaved off, no attempt should be made to remove the band of white tissue just named. We do not disturb this with the knife, but submit it to a thorough cauterization with a solution of bichlorid of mereury, five grains to an.ounce of distilled water. This cauterization is per- formed with a very small, firmly rolled cotton swab; it is dipped into the solution until saturated, after which most of the solution is squeezed out so that the © Swab is just nicely moist. This is done to prevent any superfluous: solution from running over the healthy cornea. The swab so prepared is held and drawn over the entire band of white tissue, using moderate pres- sure and repeating the process seven or eight times, using a fresh swab each time. When the.swabbing has been completed the parts should have a dry, woolly appearance. The cow is allowed to revive from the chloroform and nothing further done for twenty-four hours, at the end of which time daily applications of a four per cent yellow oxid of mereury ointment are begun, plac- ing a small piece of the ointment between the lids only. After a week these applications are made every other day, until another week has elapsed. They may then be discontinued and the case usually considered cured. An opaque area will remain in the vicinity of the original lesion. ‘When the disease has been allowed to progress until there are several thicknesses of granulation tissue and the eye is discharging a muco-purulent fluid the above treatment is of no avail. If it is demanded that some- thine be done the surgeon should advise a complete enucleation of the eye and its adnexa. ‘The sooner this operation is undertaken the better. We do not advise enucleation unless the animal is especially valu- AMAUROSIS 20 able for some reason or other. The operation is not always followed by satisfactory results and unless there is an exceptionally good reason for resorting to this measure we recommend slaughter in the severe forms of this disease. -AMAUROSIS This is nearly always a disease of pregnancy when it occurs in cows. In one instance a case occurred in our practice as a sequel to parturient paresis. The whole symptom complex of amaurosis is blind- ness. There are no lesions in the eye or in its appendages which the examiner can detect; the organs have a per- feetly normal appearance. | When the disease occurs during the pregnant state it begins usually during the last weeks of the period. The veterinarian is informed that the cow suddenly went blind. Aside from her inability to see, she is in good health. Amaurosis occurring under these conditions is a transient disease, which disappears at parturition or very soon thereafter. The case occurring in our practice as a sequel to parturient paresis persisted for some weeks. Ulti- mately a course of potassium iodid terminated the ease satisfactorily. . It is very doubtful whether any treatment should be attempted in cases occurring in the latter weeks of gestation. Knowing that the condition is entirely ‘the result of the pregnaney and that it will correct itself spontaneously with the arrival of the calf, we can usually serve the patient and our client best by 26 SPECIAL CATTLE THERAPY advising against direct interference with the trouble by* medical means. If the condition should persist after the parturition we would advise a course of po- tassium iodid internally. EPISTAXSIS Nasal hemorrhage can occur in cattle as the result of injuries and contusions under the same cireum- stanees that it occurs in other animals. The particular form of epistaxsis which we will discuss here is that form which occurs now and then in cows during the period of gestation, and not as the result of trauma. The cows which are the subjects of a hemorrhage of this nature are generally aged cows in somewhat unthrifty condition. They are most frequently affected during the lat- ter period of pregnancy, usually when about four to six weeks before calving. The symptoms are pre- cipitated by a somewhat profuse flow of blood from one or both nostrils, amounting on occasions to sev- eral pints. The flow stops of its own accord in most eases, after a few hours. The cow is off feed for a day or two and nothing further of note follows. After five or six days, sometimes a week or ten days, the hemorrhage recurs, leaving the cow usually in a dejected, weak condition. Three or four such hemorrhages may oceur before the close of gestation, after which they do not occur again. Evidently the pregnant state is responsible for the condition in some manner, it be- ing distinetly a disease of pregnancy. If the hemorrhages are severe enough and recur at short intervals, the cow is in poor condition to sur- EPISTAXSIS 27 vive the ordeal of parturition and its probable com- plications. The milk output is decidedly curtailed and sometimes entirely lacking. If there should happen to be a considerable degree of dystocia, or an infeec- tion following on complete or partial retention of the secundines, the cow will probably succumb. It has been our experience that, where the case comes into our hands at the time of the first hemor- rhage or soon thereafter, we can carry the cow through the period of gestation to an uneventful parturition, and prevent recurrence of the hemorrhage. Our remedy is iron, and we give it in the form of the tincture of ferric chlorid once or twice a day in one ounce doses, diluted with water. No further bleeding occurs and the cow improves in condition promptly. HEMORRHAGE FOLLOWING DEHORNING Dehorning is now and then followed by persistent bleeding, the subjects as a rule being unthrifty young- sters. Fatal hemorrhage after dehorning is very rare, but we have seen alarming symptoms, a good many times, result from prolonged dripping in weakly stock. While it is not a very difficult matter to control the hemorrhage, the means employed should do as little damage as possible. We have frequently seen severe catarrhal involvement of the sinuses and nares from injudicious treatment of a hemorrhage of this kind. If the patient is quite young and tractable, the best means for checking the bleeding consists of a wad of absorbent cotton and a bandage. The cotton can first be saturated with an ordinary antiseptic solution; it 28 SPECIAL CATTLE THERAPY is then applied on the horn stump and tightly ban- daged in place. If the animal is confined in a stan- chion, a rope securely tied across the stanchion up- _rights can serve the purpose of keeping the head raised for an hour or two. The bandage may be left in place for ten or fifteen hours, after which it is cut across and allowed to come off of its own accord. In other animals, or those which will not submit to bandaging, the best effect is obtained from prolonged irrigation of the bleeding stump with a very warm solution of potassium permanganate not more than one per cent strength. Fifteen minutes:of continued irrigation with this agent by means of a fountain syringe gives good results. The syringe should be hung high enough to give considerable force to the stream. In all cases the head should be held high by means of halters and ropes. A hypodermic injection of atropin sulphate, from one-fourth to one-half grain, assists materially in checking the flow. We condemn the use of Monsell’s solution and Mon- sell’s powder in hemorrhages of this nature. When the solution is used, sinus and nasal ecatarrh result almost every time; when the powder is used, suppura- tion always occurs under the scab around the base of the stump. WIRE CUTS 29 WIRE CUTS AND OTHER LACERATED INJURIES Space is devoted in this treatise to the above con- ditions chiefly with the object of impressing on the practitioner the fact that even the most extensive cuts and tears unite beautifully with proper suturing. This is especially noteworthy when the cuts or lacera- tions are in a location where no tendons or articula- tions are involved in the trauma. Sutures should be set well back from the edges of the wound and a heavy, braided silk suture material should be used. If care is taken to provide ordinary drainage for the wound, the sutures will not tear or slough out, but remain in place until healing is com- plete. It is well to select a strong needle for the. purpose and a needle holder is almost indispensable because of the extreme toughness of the skin. A daily irrigation of the wound with an antiseptic solution is all that is necessary as after-treatment. Exuberant granulations do not occur. Wounds of this nature treated during the warm months must be protected from the activities of flies. For this purpose we find an excellent and cheap preparation in one part oil of cajuput shaken up with two parts of olive oil. This is painted around the edges of the wound with a small brush or feather several times daily. The oil of cajuput alone acts very well as a ‘‘fly-chaser,’’ but used alone repeat- edly it is slightly irritating and evaporates too quickly. The olive oil overcomes both of these objections. Another satisfactory fly repellent is composed of phenol one part; turpentine one part, and olive oil or cottonseed oil sixteen parts. 30 SPECIAL CATTOR THERAPY ACUTE ARTHRITIS Acute arthritis is seen quite frequently in cows.
