ame asthose seen in every severe subacute or chronic catarrhal or ulcerative cys-titis, epithelia from the deepest layer of the bladder being rarely absent.Many epithelia contain endogenous new-formations, and these are not in-frequently seen in the accompanying epithelia from the ureters. Pus-corpuscles and fat-globules in varying numbers, together with mucus-threads, complete the features in these cases. CARCINOMA. The varieties of cancer developing in the bladder are principally the*)villous, the epithelial, and the medullary, the first two being more com-mon than the third. Villous or papillary cancer, the so-called cauliflowergrowth, is probably due in many cases to a secondary malignant changeof a previously benign papilloma. This can be proved in those cases inwhich a tumor, having lasted for years and having always given the char-acteristics and features of a benign papilloma, becomes changed and as-sumes the features of malignancy. Such a villous cancer is in reality only PCT

Medullarycancer, perhaps the most malignant, that is, most rapidly fatal of all can-cers, does not often develop in the bladder, and if it does, can hardly bedistinguished by an examination of the urine, unless large masses of thetumor are cast off.
