TUMORS OF THE BLADDER.
Recorded cases of sarcoma (Mauri), carcinoma (Cadeac, Hink, Friedberger), and tuberculosis can be adduced. Papilloma is perhaps as frequent as any of the above. The author has treated two cases of papilloma in mares complicated with multiple small calculi and gravel. Treatment is exclusively surgical and in the mare with the widely dilatable urethra this is sometimes possible through that channel. In the same animals diagnosis may be accomplished by introducing the finger into the urethra and bladder. In other females and males, vaginal or rectal palpation must be resorted to.
