Of late tubercular disease of the udder in cows (Pl. XXXVIII) has received considerable attention from sanitarians, owing to the infection of the Page 58 8 matches of the cases tested. The relatively few failures in diagnoses are included among two classes of cattle. The first class contains those that are tuberculous, but which do not react ei Page 59 15 matches unanimity of opinion on the part of all who are best calculated to judge that such an injurious effect does not occur.

It is therefore of interest to conclude this article with a brief discussion of the disease in man and its relation to actinomycosis in cattle.

done. When the animal has fallen, apply cold water or ice to the head; rub the body and limbs with cloths or wisps of straw and continue the rubbing for a considerable time. If the power of swallowing is not lost (which may be ascertained by pouring a little cold water into the mouth), give 3 drams of stronger liquor ammonia, diluted with a quart of cold water. Be very careful in drenching the animal when lying down. Repeat the drench in a half hour and an hour after the first one has been given. Instead of the ammonia, a drench composed of 3 ounces of spirits of nitrous ether in a pint of water may be given, if more convenient, but the ammonia drench is preferable. If unconsciousness continues, so that a drench can not be administered, the same quantity of ammonia and water may be injected with a syringe into the rectum. The popular aqua ammonia, commonly called "hartshorn," will do as well as the stronger liquor ammonia, but as it is weaker than the latter the dose for a cow is about 1-1/2 ounces, which should be diluted with a quart of water before it is given to the animal, either as a drench or an enema. When ammonia can not be obtained, an ounce of tincture of digitalis may be given. As soon as the animal is able to rise it should be assisted and moved to the nearest shelter. All the cold water it will drink should be allowed. The ammonia or spirits of nitrous ether drench should be administered every three hours so long as there is much failure of strength. The diet should be limited for several days--bran slops and a little grass. When signs of returning strength are presented, 12 ounces of Epsom salt dissolved in a quart of warm water may be given in those cases which have been down and unconscious, but do not give it while much weakness remains, which may be for several days after the attack. The flesh of an animal that is suffering from heat stroke should not be prepared for use as food. On account of the fever with which the animal suffers, the flesh contains toxins that may render it poisonous to the consumer. INJURIES TO THE SPINAL CORD. The spinal cord is liable to concussion from blows and falls, and paralysis, to a greater or less extent, may be the result. Fracture, with displacement of the bones (vertebrÊ) which form the spinal column, by compressing the spinal cord, produces paralysis, which varies in its effect according to the part of the cord that is compressed. If the fracture is above the middle of the neck, death soon follows, as communication between the brain and diaphragm (the essential muscle of inspiration) is stopped. When the fracture is farther down in the neck, posterior to the origin of the phrenic nerve, the breathing continues, but there is paralysis in all parts posterior to the fracture, including the fore and hind legs. When the fracture is in the region of the loins the hind legs are paralyzed, but the fore legs are not. If the fracture is in the sacrum (the division of the spinal column between the loins and the tail), the tail alone is paralyzed. As a matter of course, when the back is broken there is no remedy; the animal should be killed at once. PARALYSIS. Paralysis, or loss of motion in a part, may be due to a lesion of the brain, of the spinal cord, or of a nerve. It may also be caused by reflex irritation. When the paralysis affects both sides of the body, posterior to a point, it is further designated by the name paraplegia. When one side of the body (a lateral half) is paralyzed, the term hemiplegia is applied to the affection. When paralysis is caused by a lesion of a nerve, the paralysis is confined to the particular part supplied by the affected nerve. As already pointed out, paralysis may be due to concussion of the spine, fracture of a bone of the spinal column with consequent compression of the spinal cord, concussion of the brain, or compression of the brain. An injury to one side of the brain may produce paralysis of the same side of the head and of the opposite side of the body (hemiplegia). Paralysis may occur in connection with parturient apoplexy, lead poisoning, ergotism, etc. CONGESTION OF THE SPINAL CORD. Paraplegia, or paralysis of the rear part of the body, is the dominant symptom in congestion or inflammation of the spinal cord. The cause is not known, but the disease is probably due to chilling. It is thought by some that some toxic influence (poison) may be responsible for its development. _Symptoms._--The symptoms usually appear suddenly and consist in inability to stand. Sometimes this is preceded by a period of excitement. The animal usually lies quietly, but sometimes it groans and tosses its head about in a way that indicates pain. Cows heavy with calf are sometimes affected with a form of paraplegia, which usually attacks them from about a month to a few days before calving. Apparently they are in good health in every respect except the inability to stand up on account of the paralysis of the hind quarters. This form is generally attributed to feeding on feeds containing insufficient protein and ash. It is most likely to occur in cows that are weak and thin. With good care and feed recovery usually occurs. _Treatment._--The animal must be given a soft, dry bed under shelter and in a quiet, airy place. It is well to apply mustard along the spine. The action of the mustard may be intensified by rubbing the skin with ammonia or turpentine. Internally give a purge of Glauber's salt. Nux vomica or strychnia (1 to 2 grain doses) may be given. Turn the cow two to four times daily and rub the legs well each time. There are instances when cows will persist in lying down (in spite of all efforts that are made to compel them to stand up), when it can not really be said that they are paralyzed. They have sensation in all parts; they can move all their feet; they can change their position; and in fact every function seems to be normally performed, but they obstinately refuse to rise or even make an effort to do so. Cases of this kind have been killed, as it was an utter impossibility to get the animal on its feet. However, there are instances when a cow, after refusing to rise when all other means had been tried, quickly jumped to her feet and showed fright upon the appearance of a dog or other terrifying object. RABIES (HYDROPHOBIA). [See discussion of this disease in chapter on "Infectious diseases," p. 358.] LIGHTNING STROKE (ASPHYXIA ELECTRICA). When an animal is struck by lightning the shock is instantaneously expended on the nervous system, and as a rule death occurs immediately; but when the shock is not fatal animation is suspended to a greater or less extent, as evidenced by prostration, unconsciousness, and paralysis. _Symptoms._--When not fatal, the symptoms vary much, according to the severity of the shock. The animal usually falls, as from an apoplectic attack, and, as a matter of course, the symptoms are such as are generally manifested in connection with concussion of the brain. The muscular system may be completely relaxed; the legs limber; the muscles flabby and soft to the touch; or there may be convulsions, spasms, and twitching of the muscles. The breathing is generally labored, irregular, or interrupted, and slower than normal. In most instances the electrical fluid leaves its mark by singeing the hair, or by inflicting wounds, burns, or blisters. _Treatment._--So long as the beating of the heart is perceptible the endeavor to resuscitate the animal should be continued. Dash cold water over the head and body; rub the body and legs; smartly whip the body with wet towels or switches. Mustard, mixed with water, should be well rubbed over the legs and back of the head on each side of the neck. Inject into the rectum 4 drams of stronger liquor ammonia, or 1-1/2 ounces of hartshorn diluted with a quart of warm water. Cautiously hold an uncorked bottle of hartshorn to the nostrils, so that some of it is inhaled, but care should be taken that too much is not suddenly inhaled. If the animal is unconscious, hypodermic injections of stimulants are indicated, such as 6 drams of camphorated oil in one dose, subcutaneously, or 20 grains of caffein or 1/2 grain of strychnin, also subcutaneously. When the animal revives sufficiently to be able to swallow, 4 drams of the stronger liquor ammonia, diluted with a quart of cold water, should be given as a drench, and the dose should be repeated in an hour. One and one-half ounces of ordinary hartshorn may be used instead of the stronger liquor ammonia, but, like the latter, it should be diluted with a quart or more of water, and even then care should be exercised in drenching. In cases where the shock has not caused complete insensibility recovery may be hastened by the ammonia and water drench, or 4 ounces of brandy diluted with a quart of water, or 8 ounces of whisky diluted with a quart of water. These doses may be given every three or four hours if necessary. After recovery from the more serious symptoms 2 drams of sulphate of quinin should be given twice a day until health is restored. If any paralysis remains 1-1/2 drams of pulverized nux vomica should be given twice a day with the quinin. The foregoing treatment is also applicable when the electrical shock is given by telephone, electric car, or electric-light wires, etc. The wounds, burns, or blisters should be treated according to the antiseptic method of treating wounds. TUMORS IN THE BRAIN, ETC. Tumors of different kinds have been found within the cranial cavity, and in many cases there have been no well-marked symptoms exhibited during the life of the animal to lead one to suspect their existence. Cases are recorded where bony tumors have been found in the brain of cattle that died suddenly, but during life no signs of disease were manifested. Post-mortem examinations have disclosed tubercles in the membranes of the brain. (See "Tuberculosis," p. 407.) Abscesses, usually the result of inflammation of the brain, have been found post-mortem. For the description of hydrocephalus, or dropsy of the brain, of calves the reader is referred to the section on parturition. (See "Water in the head," p. 179.) Chorea, constant twitching and irregular spasmodic movements of the muscles, has been noticed in connection with or as a sequel to other affections, as, for example, parturient apoplexy. Various diseases, the description of which will be found in other sections of this work, affect the nervous system to a greater or less extent--for example, ergotism, lead poisoning, uremia, parturient apoplexy, colic, and other affections associated with cramps, or spasms, etc. Disease of the ovaries or of the spinal cord, by reflex irritation, may cause estromania (see "Excess of venereal desire," p. 148, constant desire for the bull). DISEASES OF THE URINARY ORGANS. By JAMES LAW, F. R. C. V. S., _Formerly Professor of Veterinary Science, etc., in Cornell University._ Of the materials that have served their purpose in building up the animal body or in sustaining the body temperature, and that are now to be thrown out as waste, the greater part is expelled from the system through the lungs and the kidneys, but the agents that pass out by either of these two channels differ in the main from those passing by the other. Thus from the lungs in the form of dioxid of carbon--the same gas that comes from burning of coal or oil--there escapes most of the waste material resulting from the destruction in the system of fats, sugars, starch, and such other foods as are wanting in the element nitrogen, and do not form fibrous tissues, but go mainly to support animal heat or maintain functional activity. From the kidneys, on the other hand, are thrown out the waste products resulting from the destruction of the foods and tissues containing nitrogen--of, for instance, albumin, fibrin, gluten, casein, gelatin, woody tissue, etc. While much of the waste material containing nitrogen leaves the body by the bowels, this is virtually only such of the albuminoid food as has failed to be fully digested and absorbed; this has never formed a true constituent part of the body itself or of the blood, but is so much waste food, like that which has come to the table and again carried away unused. If the albuminoid food element has entered the blood, whether or not it has been built up into a constituent part of the structure of the body, its waste products, which contain nitrogen, are in the main expelled through the kidneys, so that the latter become the principal channels for the expulsion of all nitrogen-containing waste. It would be an error, however, to infer that all nitrogenous food, when once digested and absorbed into the blood, must necessarily leave the system in the urine. On the contrary, in the young and growing animal, all increase of the fibrous structures of the body is gained through the building up of those flesh-forming constituents into their substance; in the pregnant animal the growth of the offspring and its envelopes has a similar origin, and in the dairy cow the casein or curd of the milk is a means of constant elimination of these nitrogen-containing agents. Thus, in the breeding cow and, above all, in the milking cow, the womb or udder carries on a work in one sense equivalent to that otherwise performed by the kidneys. Not only are these organs alike channels for the excretion of albuminous products, but they are also related to each other structurally and by nervous sympathy, so that suffering in the one is liable to induce some measure of disorder in the other. As in the case of other mammals, this nitrogenous waste matter is mainly present in the urine of cattle in the form of urea, but also, to some extent, as hippuric acid, a derivative of vegetable food which, in the herbivora, replaces the uric acid found in the urine of man and carnivora. Uric acid is, however, found in the urine of sucking calves which have practically an animal diet, and it may also appear in the adult in case of absolute, prolonged starvation, and in diseases attended with complete loss of appetite and rapid wasting of the body. In such cases the animal lives on its own substance, and the product is that of the wasting flesh. The other products containing nitrogen are present in only small quantities and need not be specially referred to. The urine of cattle contains much less of carbonates than that of the horse, and effervesces less on the addition of an acid. As the carbonates form a large proportion of the solid deposits (gravel, stone) from the horse's urine, the ox may thus be held less liable, yet even in the ox the carbonates become abundant or scanty, according to the nature of the feed, and therefore gravel, formed by carbonate of lime, is not infrequent in cattle. When fed on beets, clover hay, or bean straw carbonates are present in large quantities, these aliments being rich in organic acids and alkaline carbonates; whereas upon oat straw, barley straw, and, above all, wheat straw, they are in small amount. In calves fed on milk alone no carbonates are found in the urine. Phosphates, usually in combination with lime, are, as a rule, present only in traces in the urine of cattle; however, on a dietary of wheat, bran, or other aliment rich in phosphates, these may be present in large amount, so that they render the liquid cloudy or are deposited in solid crystals. The liquid is rendered transparent by nitric acid. The cow's urine, on a diet of hay and potatoes, contained: Parts.
