INFLAMMATION OF THE PREPUCE IN SWINE AND IN CARNIVORA. 655 



bulls injections of sublimate (1: 1,000), or zinc chloride, 5 per cent., 

 should be tried. 



When the subcutaneous tissue about the sheath is infiltrated 

 with urine, incisions are made, the parts pressed to remove the con- 

 tents, and the skin and wounds frequently cleansed. 



(3.) INFLAMMATION OF THE PREPUCE IN SWINE. 



The prepuce of the boar consists of an inversion of the skin, bnt the 

 inner surface is formed of mucous membrane containing numerous lymph 

 follicles. On the upper wall of the sheath, and close in front of its opening, 

 is the " umbilical pouch " (nabelbeutel) formed by folding of the mucous 

 membrane, which, when distended, often attains the size of a hen's egg. 

 It is lined by squamous epithelium, and contains numerous sebaceous and 

 sudoriferous glands, hence smegma not infrequently accumulates at this 

 point, and, becoming inspissated, may produce " preputial calculi." 



In swine, only the castrated animal seems to suffer from 

 inflammation of the prepuce ; the causes are similar to those in oxen. 

 They consist in accumulation of smegma in the prepuce, or in the 

 above-mentioned appendix ; if swine were not slaughtered so early 

 in life, the condition would probably be seen more frequently. 



Symptoms. The prepuce is swollen, painful, hot, its orifice 

 contracted, and not infrequently there is difficulty in urination. 

 A stinking sebaceous material escapes on pressure. This material 

 sometimes stops up the prepuce and fills the umbilical pouch causing 

 it to protrude as a round swelling above the end of the penis. 



Treatment is on the same principles as in cattle, and consists 

 in evacuation of the sheath and pouch cleansing and disinfection 

 as far as possible. The same materials may be employed as in oxen ; 

 sometimes it is necessary to lay open the sheath. 



(4.) INFLAMMATION OF THE PREPUCE IN 

 CARNIVORA 



Presents somewhat different features to the corresponding condition 

 in bulls, oxen and horses. Apart from accumulation of smegma, 

 infection or accidental injuries, preputial inflammation is rare in 

 these animals but dogs suffer frequently from chronic catarrh of 

 the inner surface of the prepuce ; indeed, most suffer from it to a 

 limited extent. 



Symptoms. The hairs clustered round the opening of the sheath 

 appear gummed together, and a purulent material discharges from 

 the prepuce. In some cases the urethra is also affected. Animals 

 are inclined to lick the affected parts, but apart from this there is
