SIMPLE TUMOURS. 



much hcemorrhage, or the mouth may be washed twice or thrice 

 a day with vinegar, which seems to have a wonderful effect in 

 destroying them. When on the eyelid, their removal must be 

 performed with great caution, or the animal may be damaged for 

 life. Gentle and repeated touches with an acid, so as to destroy 

 a thin pellicle at a time, is the best method for their removal 

 when so situated. 



The "grapes" of chronic grease are similar to warts, con- 

 sisting of thickened epidermis and of enlarged papillae and 

 sebaceous follicles; they are best removed with the actual 

 cautery ; shaved off, in fact, by a sharp-edged piece of iron 

 heated to a red heat. 



Another kind of epithelial tumour is found in the vagina, 

 especially of the bitch, larger than a wart, with a lobu- 

 lated surface, and much vascu- 

 larity, having a tendency to bleed. 

 Several of these vegetations by con- 

 fluence form a large tumour ; they are 

 to be removed by being enclosed in 

 j a clam, and cut off by the cautery. 

 They may be named as vascular epi- 

 thelial tumours.

 they must be removed by excision, and the sac destroyed by a 

 slight touch of the actual cautery or a caustic wash. Vaginal 

 tumours sometimes consist of fat cells. The tumour from 

 which the microscopic view is taken weighed 2 lbs. 5 oz., and 

 was removed from the vagina of a cow by Mr, Cartwright of 

 Whitchurch.

The term neuroma is applied to a fibrous tumour connected 

 with the nerves. In the human being they are of frequent 

 occurrence, several hundreds of them being found in one sub-
