It is of an oval form, the extremities of the oval directed upward and downward, varies in size in different subjects, and is much larger in the male than in the female.

The internal ring is bounded, abocc and externally, by the arched fibres of the Trans^?e^salis; below and internally, by the deep epigastric vessels. It transmits the spermatic cord in the male and the round ligament in the female. From its circumference a thin funnel-shaped membrane, the infundibuliform or internal spermatic fascia, is continued around the cord and testis, enclosing them in a distinct EMORAL AHTERY GIMBERNAT-S LIGAMENT LIGAMENT Fia. 328.—The relation of the femoral and internal abdominal rings, seen fn removal of the peritoneum.

The Inguinal or Spermatic Canal (canalis inguinalis) (Figs. 329 and 330).—^The inguinal or spermatic canal contains the spermatic cord (Junicuhis sperinaticus) in the male and the round ligament (ligamentum teres uteri) in the female. It is an oblique canal about an inch and a half in length, directed downward and inward, and placed parallel to and a little above Poupart's ligament. It commences above at the internal or deep abdominal ring, which is the point where the cord enters the spermatic canal, and terminates below at the external ring. It is bounded in front by the aponeurosis of the External oblique throughout its whole length, and by the Internal oblique for its outer third; behind, from with
