DISEASES OF DOMESTIC AMIMALS. 189 



to induce suppuration. Give hydrocyanic acid, belladonna, etc.; treat 

 it just as a nervous fever ; give a generous diet and bromide of 

 potassium. 



Amaurosis results, and is some1;jmes due to excessive hemorrhage ; 

 and if it is, the eyes will regain their natural condition as the system 

 gains strength. But it sometimes occurs through a sympathetic 

 nervous influence, and remains during life. 



(xianders and Farcy, — When this does appear, I think the infec- 

 tion had been in the system before the operation, and it is due to con- 

 tagium in some form or other. 



Operating upon Originals. — I cannot speak from experience. 

 Prepare the animal, and make an incision as in other animals ; insert 

 the fingers, and if the testicle is in the inguinal canal, get hold of it 

 and draw it out, and take off with the ecraseur. If it is in the 

 abdominal cavity, it is more difficult, but several of our graduates 

 have performed the operation successfully. Some claim that they go 

 behind Poupart's ligament ; others pass the hand up the inguinal 

 canal and break through the peritoneum with one finger, and the 

 testicle will generally be found on the fundus of the bladder. How- 

 ever, the operation requires practice. 



THE TESTICLES. 



Inflammation of the Testicles. — This is not common in the lower 

 animals. The causes are injury of some kinder other — sometimes, in 

 a stallion, from a kick, or exposure to cold. It is caused in a bull in 

 the same manner, and occasionally from tubercular deposits, but 

 usually from direct injury. The symptoms are generally plain, and 

 your attention is usually directed to it. There is intense pain in the 

 early stage ; a slight injury to these organs sets up great pain ; and 

 when the whole organ is affected, the pain is intense, and they some- 

 times become enormously swollen in a very short time, and swelling 

 generally affords some relief; he walks with great difficulty, and it 

 increases the pain ; he will sometimes lie down and attempt to roll, 

 but generally continues standing; lying down increases the pain. 



Treatment. — If in a valuable stallion, he is generally in high con- 

 dition, in which case it is necessary to give a good dose of purgative 

 medicine, or blood-letting may be necessary ; take six, eight or ten 

 quarts of blood ; or, instead of this, give aconite ; bathe at first with 

 tepid water and increase the heat, and bathe for several hours and 

 keep heat to the parts ; you can do this by means of a bandage over 

 the loins, kept in its place by means of a surcingle ; keep cotton or 

 cloths to the parts, and keep them supplied with warm water ; give 

 belladonna or laudanum. Local blood-letting is beneficial, but it is 

 difficult to perform in the horse. During the early stage the appe- 

 tite is entirely gone, and when he is relieved and the appetite 

 returns, he should be fed sparingly. Give diuretics freely ; sweet 

 spirits of nitre, iodide of potash, etc., which increases the action of 

 the kidneys, and stimulates the absorbents. If, after the irritation 

 subsides, enlargement of the testicles remains, use iodine, both inter- 

 nally and externally, which, it is said, if used for some time, will 

 reduce the size of the testicle. The treatment of the balls is similar, 

 but it is associated with tubercular disease. You may allay the irrita- 

 tion, but the animal will generally remain impotent. 



Hydrocele Dropsy of the testicle and scrotum is most likely to take
