 These are usually melanotic, and belong to the variety of 

 either the adenoma, fibroma, or papilloma ; they are easily 

 removed either by ligature or scalpel. The preputial tissue 

 may also be infected with carcinoma and sarcoma. 



Inside the prepuce and on the mucous surface of the penis 

 one meets with another variety, the infective venereal tumour, 

 which is indistinguishable, microscopically, from a sarcoma.^ 

 It appears to be most commonly met with in the bulldog 

 variety, and the author has also seen it in St. Bernards,
