Pig. 50 — Intra-Inguinal Cryptorchid (Bayer). A, Testes Inside Abdominal Cavity; 

 B B, Internal Abdominal Wall; C, Spermatid Cord Inside Inguinal Canal; D, Tunica 

 Vaginalis; E E, Dotted lines indicate outlines of Spermatic Cord; P, Internal Abdominal 

 Ring; G, Inguinal Canal.

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

 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

 internal abdominal ring into the inguinal canal. If successful,
