time opposite the posterior part of the bone of the penis, the urethra 

 laid open, and the tissues covering it removed in the shape of an 

 inverted V. To prevent further loss of blood the lips of the wound 

 were cauterised without touching the margins of the urethra. The 

 result of this second operation was good ; the urethral orifice remained 

 permanently free. 



CANCER OF THE PENIS. 



ii8. A twelve-year-old gelding, left in hospital 15th January, 1897. 



Had been in its then owner's hands since 1889. No previous 

 disease. A month before the horse was noted to have difficulty in 

 "drawing the penis'" when staling. A veterinary surgeon, who was 

 called in, discovered a tumour on the penis and recommended its 

 removal. The horse worked up to the day of entering hospital. 



At the time of examination the horse was in good condition, and 

 did not appear to suffer from the disease. The sheath was swollen, 

 and discharged a little blood-stained foetid pus. On introducing the 

 hand a hard, indolent tumour was found on the penis. When the 

 organ was withdrawn it appeared of large size, and its lower third was 

 covered with blackish, friable cauliflower vegetations. The upper part 

 of the new growth was sharply defined. Microscopic examination of a 

 fragment showed it to be ot a cancroid nature. 



r7'^a/;;z^;z/.— Amputation of the penis above the tumour. On the 

 i8th the horse was cast on the left side and secured, as for castra- 

 tion. The inguinal region having been disinfected, an elastic ligature 

 was applied to the base of the penis to check haemorrhage. Ampu- 

 tation was performed by the method described on p. 61. On the 

 horse returning to its stall some haemorrhage occurred, but only in drops. 



During the evening the animal showed signs of trifling colic. The 

 mucous membranes were slightly injected ; the pulse accelerated, 

 respiration normal, temperature 38"5° C. Haemorrhage returned 

 during the night, the blood escaping sometimes by drops, sometimes 

 in a thin stream. The sheath was washed out with warm 2 per cent, 

 creolin solution. 



The part of the penis removed was five times the normal size, and 

 covered with blackish, very friable, irregularly arranged vegetations, 

 some the size of a hazel nut, others larger than a walnut. The urethral 

 orifice was thrust towards the left side and masked by a large growth. 

 All the lower half of the penis was dotted over with little greyish 

 tumours resembling papillomata. 



On the 19th the general condition was good. There was no fever. 

 Micturition was performed easily. The sheath was washed out with 

 lukewarm antiseptic injections. 



Next day the sheath showed swelling, which increased for several 

 days. On the 26th it was less swollen and sensitive. On the 27th the 

 portion of the stump destroyed by the ligature separated. Urine was 

 easily passed ; the animal left hospital on the 29th January. There was 

 no after contraction. 



After disinfecting and scarifying the integument of the glans penis 

 in a horse retained for experiments, we attempted to inoculate the new
