large number, but have only met with it in one coloured animal — a light 

 roan heifer. The animal rarely shows any indications of the complaint 

 until it has been served ; then the symptoms are developed m a period 

 varying from 12 hours to 6 weeks, the principal portion of the cases 

 occurring in from 12 to 20 days, when the patient is noticed to erect 

 its tail, and strain and press, as if about to calve. Any faeces which 

 may be in the rectum is forcibly ejected, and in severe cases the 

 rectum is turned out, and bloody mucus is discharged from the vagina. 



762. After learning the history of the case, the operator should oil 

 his hand, and introduce it gently into the rectum. Immediately the 

 hand is passed through the anus, a tense, more or less, distended body 

 is felt beneath the floor of the bowel. By passing the hand further 

 forward, this bladdery distension is found to extend mto the cavity of 

 the belly. Understanding what is amiss, he should withdraw the hand 

 and pass the fore-finger of the left hand into the vaginal passage, 

 when, immediately m front and above the neck of the bladder, the 

 obstruction will be found, and a roughening felt, a result of the 

 penetration of the male organ in the act of serving. Treatment — 

 For relief, an operation is necessary. A trocar and canula (the latter 

 being 10 inches long and f of an inch in diameler— Plate XLIX., 

 fig. 11), is passed up along the vagina and guided by the fore-finger 

 of the left hand (the point of the trocar being withdrawn into the tube) 

 until the roughening in question is reached, when both are forced 

 through the obstruction into the bladdery tumour {Plate XL., B). 

 The trocar is then withdrawn, the fluid passing through the canula, 

 while its escape is very much assisted by passing the hand into the 

 rectum. The parts are next washed out with a gallon or two of tepid 

 water containing one ounce of tincture of iron. I have also operated 

 upon animals that have not been served ; (one case being that of a 

 white heifer, nine months old), the fluid in these cases is like dirty 

 milky-whey with a very fcetid smell, while in those who have been 

 served the fluid is of a dirty brown colour, with a " stink " resembling 

 that of a decayed cleansing.
