labourers, who seem to consider this an excellent joke. 

 Some hasmorrhage will take place through the external 

 opening, and later, a discharge of a muco-purulent cha- 

 racter will appear. Manual exploration of the parts will 

 disclose the lesion. Cases of this kind do not seem to 

 be attributable to the penis of the bull. During birth 

 a foot of the foetus may be forced into the rectum and 

 protrude through the anus, or pass into the areolar tissue 

 around the vulva. The throes being powerful, more or 

 less laceration occurs, and thus in some cases the peri- 

 nseum may be entirely lacerated and the anus and vulval 

 opening become continuous with one another. This lesion 

 is seldom seen in the cow. When the foot protrudes 

 through the anus it must be returned as soon as possible, 

 and the calf removed through its normal passage. There 

 is after this great liability to Eecto-vaginal Fistula, 

 which must be avoided as much as possible by keeping 

 the contents of the rectum soft, whereby they can pass 

 easily, and by adopting dressings calculated to promote 

 speedy healing of the orifice. 



Yesico-Yaginal Fistula is not frequent. It causes in- 

 continence of urine, and the fistula can hardly be got to 

 heal because of the constant passage of the urine. A 

 rupture of the vagina may be far enough forwards to 

 admit of protrusion of the intestines and to be compli- 

 cated with peritonitis. Injuries, and especially bruises 

 during parturition, are rather liable to cause blood 

 tumours, Hamatomataj in the erectile tissue of the bulb 

 of the vagina. 



Leucorrhcea — '^ The WJiites/' — Yaginitis sometimes 

 results from injury, but generally subsides rapidly, and is 

 represented by a chronic form of inflammation of the 

 lining membrane of- the vulva and vagina, which in some 

 cases is ulcerated, in others simply thickened, and some- 

 times is the seat of scrofulous deposit. It may be more 

 or less extremely diseased. The discharge varies in 

 amount and in consistence also in constancy of flow. It 

 may be quite white and profuse, or purulent or sangui- 

 neous. Also the constitution is variably aflected; there
