424 CLINICAL VETERINARY MEDICINE AND SURGERY. 



apple projected, and was at first regarded as a perineal hernia. On 

 introducing the index finger into the rectum, however, the inferior 

 surface of the latter was found to be compressed by a kind of cyst. The 

 patient was secured to the table and operated on by M. Almy. 



On dilating the vulva we discovered about half an inch from the 

 orifice a tensely stretched mucous partition, which projected backwards 

 and exhibited fluctuation. At first it was regarded as the distended 

 bladder, or a submucous cyst. On passing a rubber catheter into the 

 bladder, however, only a little normal urine was withdrawn. The 

 finger could not be introduced into the vagina, the above-mentioned 

 partition closing the entrance. The swelling was punctured with a 

 trocar, when about a pint of viscous, yellowish pus-like liquid escaped. 

 The pocket was laid open and part of the partition removed with curved 

 scissors. The vagina and uterus were washed out with boiled water 

 until the liquid returned clear. 



During the following days the vagina was irrigated with boric acid 

 solution. The symptoms noted before operation rapidly disappeared, 

 and the bitch w^as sent home cured on the 5th July. 



AMENORRHCEA DUE TO IMPERFORATE HYMEN. 



134. A " six-quarter " Ayrshire quey in fat condition, first seen 

 nth September, 1894. 



History. — Had been straining at intervals for five days, the pains 

 daily becoming worse. A dose of physic had given no relief. 



State on Examination. — Appetite lost ; head depressed, face anxious ; 

 the animal strained almost constantly and groaned loudly at intervals. 

 During the more severe pains about two inches of the rectum in a 

 bleeding state were protruded. Skin clammy ; ears and horns alter- 

 nately hot and cold. Temperature i04'5° F. ; pulse 115, rather weak. 

 Rectal examination revealed the presence of a large ovoid painful 

 swelling almost filling the pelvic cavity. On exploring the vagina the 

 hymen was found to be imperforate and impossible to rupture by 

 manual exertion. 



Treatment. — After administration of a full dose of chloral the 

 hymen was punctured with an embryotomy knife, and broken down 

 throughout by the fingers. Four pints of putrid steel-grey fluid con- 

 taining whitish and reddish flocculi were ejected. After washing out 

 the vagina with a weak tepid solution of Jeyes' fluid, the os was found 

 to be apparently normal. Stimulating liniment was applied to the 

 croup, and chlorodyne given internally to check further straining. 

 Pains entirely ceased twelve hours after operation, and on September 

 13th the quey was doing well.

EPITHELIOMA OF THE VULVA. 



135. An aged cow. 



History. — The tumour had been noticed eight months previous to 

 the photograph being taken ; it was then the size of a mandarin orange. 

 It grew rapidly and caused the animal much inconvenience, as shown
