224 AMPUTATION OF THE PENIS IN THE HORSE. 
■ M. Barthelemy attempte>l to enlarge the opening and introduce 
a canula, but the retractibn of the penis rendered this imprac¬ 
ticable. He then determinated to make an incision into the 
urethra from the perinaeum, but there was no possibility of in¬ 
troducing a sound. He however cut into the urethra, and emp¬ 
tied the bladder. A sound was now passed through this 
wmund, and carried to the.extremity of the urethra; a crucial 
incision was made on this newly formed skin, which had imped¬ 
ed the flow of the urine, and a canula was forced through it. 
The other end of the canula was now passed into the wound in 
the perineeum, and carried a little way up the urethra and 
• there secured, so that the urine flowed principally through the 
canula, but partly through the wound in the perinaeum. In a 
few days the animal was again sent to work. The canula ’was 
taken out every two or three days to be cleaned, and in about 
two^ months the upper wound had healed, when the canula was 
finally withdrawn .—liecueil de Med, Vet. Fev, 1828. 
Amputation of the penis has been performed several times at 
our veterinary college. No canula is introduced; but the 
sheath is turned back, the penis drawn out as far as possible, 
and then cut through with a bistoury at one or Uvo incisions. 
The remaining part of the penis is immediately retracted. Little 
hemorrhage is produced, except that for a few days in the act 
of passing urine a slight bleeding ensues. The orifice of the 
urethra is kept sufficiently open by the gush of the urine, and 
no untoward circumstai^ce has arisen. 
We much prefer this simple mode of performing the opera¬ 
tion. The separation by ligature is slow and painful. The in¬ 
troduction of a canula previous to the operation, can effect no 
good purposes. It cannot be retained; and the act of cutting 
on it, may render the incision more irregular, ^nd more likely 
to close at the orifice of the urethra, and produce partial or 
total suppression of urine. Edit.
