CASTRATION OF CRYPTORCHIDS.

>ptorchidy, the depth is only from 5 to 6 centimeters, while, 
Teasing from inward, outwardly, on account of the obliquity 
ward which has been acquired by the bottom, it easily meas- 
3S 10 and 12 centimeters at the external angle. This is a pe- 
liarity worth noticing, since from this fact arises one of the 
>st important of the indications of the operating steps, viz., the 
rforation of the inguinal interstice. The indication is this: 
The external inguinal ring forming the entrance to the ingui- 
1 interstice having been exposed by the division of the scrotum 
d dartos, and by the laceration of the conjunctive tissue be- 
ath, the hand is carried upon this ring, whose internal commis- 
e and posterior pillar are easily found. Introduced into the 
ig it is then pushed into the interstice, outward and upward 
ward the flank, in order to pass by the side of the external 
gle of this interstice without breaking the small resistance it 
ii» 
rers. 
By this mode a part much nearer the sub lumbar region is 
ached than could be otherwise without going beyond the ex- 
rnal quarter of the crural arch than when the hand is further 
om the internal angle or prepubic tendons. 
Numerous post mortem examinations of pseudo operations 
ade upon dead animals have shown that the hand pushing for¬ 
ward the fleshy portion of the small oblique muscle and lacerating 
e cellular tissue of the inguinal tract, reaches the peritoneum 
lacerate it at about 18 centimeters from the linea alba, or 
ore commonly from 12 to 15 centimeters. 
The hand then drawn, the fleshy portion of the small oblique 
treats upon itself, comes to lie against the crural arch, and 
oses the interstice. Again, when the animal is in a standing 
isture, the opening of the peritoneum being in a portion of the 
)dominal wall, the intestines have no tendency to engage into 
; a double result which will in a majority of cases prevent peri- 
>nitis and hernia. And again, through this peritoneal lacera- 
on, it will always be an easy task to bring the testicle out of the 
idomen in order to remove it. 
If, on the contrary, the bottom of the interstice has been 
icerated near the median line, the artifical peritoneal opening
