372 CLINICAL VETERINARY MEDICINE AND SURGERY. 



When the sac contains a horn of the gravid uterus it is freely opened 

 and hgatures appHed to the pedicle of the ovary, the base of the horn, 

 and the corresponding half of the broad ligament, and drawn thoroughly 

 tight, the parts being excised four inches below the ligatures. Before 

 returning the stump of the horn the mucous membrane is scraped and 

 disinfected with strong carbolic solution. 



Wherever asepsis appears doubtful, a drainage-tube or strip of gauze 

 should be inserted and sutured to the skin to allow of discharges 

 escaping. 



8i. A two-year-old Danish dog, left in hospital 14th October, 1894. 



Three months before a hot, cedematous, painful swelling was noted 

 on the lower surface of the abdomen, immediately in front of the right 

 stifle, accompanied by lameness in the right hind leg. Swelling and 

 pain disappeared in the course of a week. The dog was suffering from 

 ventral hernia. 



Condition on Entry. — In the lower portion of the right flank, slightly 

 in front of the stifle, was an ovoid swelling, the size of an egg, painless, 

 uniformly fluctuating, and readily reducible. 



The animal having been placed on its back one could, after reduction, 

 pass the end of the index finger into the hernial opening, which was of 

 considerable size and elliptical in form. The animal was prepared as in 

 the preceding cases, and operation was performed on the 18th October 

 under chloroform. 



The skin having been disinfected, an incision about three to three 

 and a half inches in length was made over the long axis of the tumour, 

 in a slightly oblique direction, downwards and inwards, and the sac 

 enucleated. Whilst an assistant exercised slight traction on the sac, a 

 double catgut ligature was passed around it, level with the opening, 

 drawn tight, the two ligatures separately tied, and the sac resected. 

 The margins of the abdominal opening were curetted and united by 

 three silk sutures. The cutaneous lips of the wound were brought into 

 intimate contact by interrupted sutures. The wound was covered 

 with collodion, over which was applied a cotton-wool dressing and 

 bandage. 



The patient was fed on milk and a little meat. In the evening the 

 temperature was 38'8° C. 



The sequelae were very trifling, the temperature never exceeding 

 39-2° C. 



On the 22nd October the dressing was removed. The upper two 

 thirds of the wound had healed throughout ; in the lower third the lips 

 were swollen, retracted, and discharging. They were cleansed with 

 carbolic solution and a new cotton-wool dressing applied. 



On the 26th the cutaneous sutures were cut and removed. On the 

 30th dressing was discontinued. The wound had healed, and the hernia 

 was cured. 



82. A five-year-old setter bitch, left in hospital 8th February, 1895, 

 Had been ill for five days, showing symptoms of intestinal obstruc- 

 tion, loss of appetite, dulness, groaning, vomiting, constipation, and
