CASTRATION OB' CRYPTORCHIDS. 309 
___________ 
ich as possible, and must be secured in the safest manner prac- 
:able. 
The washing of the sheath is a good measure. Anaesthesia 
ght to be employed, as much to relieve the patient from pain 
to facilitate the manipulations of the surgeon. 
If the kind of cryptorchidy has not been detected while the 
imal was standing, it often becomes easier to do so when he is 
>wn and well secured. The instruments necessary are : Scis- 
rs, convex bistoury, forceps, tenaculum, clamps, ligatures or 
raseur, as the case may be. Oakum, needles and quill sutures 
ight to be always ready. 
Operation. 
Method by the perforation of the inguinal interstice. —This is 
vided into two parts. The first, which is the same in both 
nds of cryptorchidy, has for its object to expose the external 
guinal ring, and to allow the surgeon to discover whether the 
sticle has descended to the groin, or if it still remains in the 
)domen. The second contemplates the prehension and ablation 
: the testicle; the means for effecting these objects vary consid- 
•ably in the two kinds of castration. 
FIRST PART. 
This includes two steps. First, Incision of the scrotum and 
i ie dartos, and secondly , the laceration of the sub-dartoic layers. 
A. — Incision of the scrotum and dartos. —At a point corres- 
onding exactly to the scrotal cul de sac, the operator makes a 
•ansversal fold of the skin, which is raised and stretched, 
nd cut through with the scalpel perpendicularly, dividing at 
ace the scrotum and the dartos. The incision is longitudinal, 
leasuring about 15 centimeters in length, and is made a little 
lore forward than backward. If the division of the dartos has 
ot blen made by the first stroke of the knife, it is carefully en- 
irged, avoiding the large divisions of the external pudic veins, 
diicli run immediately under the skin, close to the median line. 
B. — Laceration of the Sub-Vartoic Tissue. —The cellular 
leshes under the dartos, more abundant and condensed in cryp- 
orchid animals than the others, cover the inguinal ring. They
