TUMOURS ON THE SHEATH AND PENIS. 
penis generally do well, that is, the distortion or bending disappears 
along with the inflammatory symptoms, though cases have been seen 
where it persisted, and rendered the animal useless for stud purposes. 
Gallimore reports a case where the end of the penis no longer became 
erect. 
Treatment must be based on general principles. To assist circulation, 
and repair and prevent the wound becoming soiled, a suspensory bandage 
is employed, and may be made the vehicle for the application of drugs, 
cold astringent lotions, creolin, &c.; the swelling which usually remains 
will thus be most rapidly removed, and for the same purpose massage 
will be found of service. 
III.—TUMOURS ON THE SHEATH AND PENIS. 
AMPUTATION OF THE PENIS. 
Fibromata, (warts) are often seen on the horse’s sheath ; according to 
my own experience, carcinomata also occur here, and melano-sarcomata 
and melano-carcinomata have been reported. Piovesau removed a fibro¬ 
sarcoma as large as a child’s head from a stallion’s sheath. Warts occur 
on the prepuce of the dog and of other animals, not infrequently in great 
numbers. They are generally situated on the inner folds, but frequently 
on the penis also. Whether condylomata occur here, as Bayer believes, 
seems questionable. 
The simultaneous appearance of warts on the mouth does not prove 
the specific nature of the new growths, because warts are also frequent 
about the lips. Cadiot removed a large papilloma weighing 12 lbs. from 
the glans penis of a dog by amputating the penis itself with an elastic 
ligature. Francesco used the ecraseur to remove an ulcerating angioma. 
Fellenberg saw a “ knobby ” swelling on the penis of the dog; Bubinski 
found in this situation cancer in geldings ; Laurent a melanoma weighing 
about 50 lbs. in a horse; Johne and Eber primary tuberculosis in an 
ox. Schwenk removed a papilloma from the glans of a stallion; it had 
interfered with copulation. 
The significance of these conditions depends chiefly on their nature 
and extent, which require to be carefully considered in delivering a 
prognosis. Tumours on the prepuce rapidly produce stenosis and 
phimosis or paraphimosis; they may also press on the urethra, or 
attack its walls and impede urination, whilst malignant tumours lead 
to disseminated secondary growths. 
Treatment. Pedunculated warts are snipped off with scissors, any 
slight bleeding being checked with the cautery or with lunar caustic, 
which at the same time tends to prevent reproduction. Large pedun¬ 
culated tumours may be ligatured or removed with the ecraseur. The
