CLINICAL VETERINARY MEDICINE AND SURGERY. 



implicated. There were no remains of healthy skin on the tumour 

 with the exception of the external borders, where it was being raised 

 by the extension of the new growth underneath. The wall of the 

 vagina for from six inches to eight inches from the posterior extremity 

 was affected, the mucous membrane being ulcerated. The animal was 

 slaughtered. 



On post-mortem many of the lymphatic glands of the abdomen, 

 especially the pelvic and the posterior mesenteric, were found to be 

 affected with small nodules, consisting of greyish-looking material of 

 soft consistency. The lungs were tubercular, and the liver contained 

 a few tuberculous nodules. 



Microscopical examination afterwards demonstrated conclusively 

 that this tumour was epitheliomatous, and also that secondary infection 

 of the lymphatic glands had taken place. The fact that the animal w^as 

 also tubercular is of interest on account of the extreme rarity of the 

 occurrence of the two conditions in the one animal.

RUPTURE OF THE PERINEUM— OPERATION. 



136. A seven-year-old thoroughbred mare, entered hospital igth 

 October, 1897, suffering from rupture of the perinaeum, consequent on 

 difficult labour. 



The wound extended from the superior commissure of the vulva as 

 high as the anus, without, however, affecting the sphincter ani. It had 

 been allowed to heal without surgical interference. When the mare 

 came in season she was covered, but unsuccessfully, the failure being 



attributed to the rupture. The parts were 

 sutured by a veterinary surgeon. Adhesive 

 union was not obtained, and some months 

 later the mare was sent to Alfort. 



State on Examination. — General health 

 good. The perinseal rupture, which ran ob- 

 liquely upwards and towards the right, started 

 from the superior commissure of the vulva, 

 and terminated beneath the sphincter ani. 

 The margins were fibrous, irregular and con- 

 tracted, and showed a large opening, through 

 which a portion of the faeces escaped, causing 

 continual irritation of the vagina. 



Treatment. — Until the 26th October the 

 mare was prepared by injections of warm 

 boric, or one per cent, creolin solution re- 

 peated twice daily, and internal administra- 

 tion of three ounces of sodium sulphate daily 

 in the drinking-water. During the last two 

 days the animal was placed on very low diet. 

 On the 27th it was cast on the right side by 

 means of the table. After evacuating the rectum the operative wound 

 was washed with soap and water and carefully disinfected.
