URETHRITIS. 



Inflammation of the lining of the urethra is called urethritis. 

 Any of the causes producing inflammation in the bladder may 

 cause urethritis. If a stallion copulates with a mare suffering 

 from leucorrhcea, urethritis is apt to follow. 



Treatment. — Mild soothing diuretics and stimulants in the 

 form of copaiba, 1 dram dose three times a day, or oil of sandal- 

 wood are good remedies. Suspend the horse's stud work. Be 

 careful about using local injection. A solution of bichloride of 

 mercury 1 to 2000 can be used and twenty-four hours after an- 

 other solution 1 to 6000. Do this twice a day for two or three 

 days. In all these cases relax the bowels with the salines. As 

 a rule the inflammation does not extend further up than three to 

 six inches, but if it does, it is due to the irritation of gravel in 

 the bladder. If the condition arises in a stallion, retire for a 

 week or two. Clean the parts with soap and water three times 

 a day and at the same time syringe mild antiseptics into the 

 urethra. Solution of sulphate of zinc two grains to an ounce 

 of water is the best. Do not manipulate the penis after injection. 



Rupture of the bladder may occur occasionally but it is very 

 rare. It is more likely to occur in the human than in the other 

 animals. It may be seen in cases of azoturia or in cases of long 

 rentention of the urine, or it may be ruptured by raising a re- 

 cumbent horse with slings without first emptying the bladder. 

 It is always fatal. 



Eversion of the bladder often occurs. The bladder protrudes 

 through the vulva, appearing like a case of prolapsus or a poly- 

 pus. Examination will tell the difference. The lining of the 

 bladder is velvety and soft and the openings of the ureters can 

 be found. Return the bladder to its proper position with a 

 probang and give anodynes and oil. 



TUMORS. 



A tumor may be defined as any prominence or growth, un- 

 natural, on the body or in any organ or gland. It may be com- 

 posed of the same tissue as where it grows, or it may be en-
