Operative Technique — The incisions are made and the scrotum 

 and inguinal invaded in the same manner as that employed in the 

 intra-abdominal variety. 



Location of the Testicle — The testicle is located by proceeding 

 carefully up the inguinal canal, at the same time making strict 

 search for the tunica vaginalis containing the spermatic cord and 

 sometimes the epidid^^nus. As soon as tunic is encountered ex- 

 amine it carefully in order that no mistake in diagnosis be made. 

 When satisfied that you are in possession of the tunica vaginalis, 

 pass hook knife up the canal sufficiently high to knick the tunic 

 and allow its contents — be they what they may — to escape into the 

 inguinal canal. You are now in possession of the spermatic cord 

 and are justified in applying a limited amount of traction in an 

 effort to bring the testicle from the abdominal cavity through the 

 internal abdominal ring into the inguinal canal. If successful,
