The obturator internus and externus nuiscles, which springfrom th(^ inner and outer surfaces of this membrane, pass toward the trochantermajor as extcn-nal rotators of the femur. The obturator canal or sulcus permitsthe passage of the obturator nerve, artery, and vein in the order named, from.

Mr. Birkett, who has especially studied the subject, writes:* After passing alongthe obturator canal, the hernial tumor emerges upon the thigh, below the horizontalramus of the pubes to the inner side of the capsule of the hip-joint, behind and a little tothe inner side of the femoral artery and vein, and to the outer side of the tendon of theadductor longus. The tumor formed by the protrusion is covered by the pectineusmuscle. It may be distinguished, therefore, from crural hernia, by observing the relativepositions of th-stock-foto
