On the right side parts of the external and internal oblique muscles together with the cremaster 

 have been taken away, so as to show the spermatic cord invested by the infundibuliform fascia lying 

 in the inguinal canal. By the removal of a part of the front of the femoral sheath the femoral vessels 

 have been exposed and the femoral canal opened. Gl., gland occupying the femoral ring. 



On the left side parts of the two oblique muscles have been removed, and also a portion of the 

 spermatic cord. Poupart's ligament has been divided, and the cut portions turned aside, thus exposing 

 the deep femoral arch. Tr. F., triangular fascia ; G. L. , Gimbernat's ligament. The conjoined tendon 

 on this side is very wide, and is prolonged outwards along the deep femoral arch as far as the internal 

 abdominal ring. 



more externally is a slight elevation, the plica epigastrica, over the epigastric vessels. 

 The depressions are accordingly three in number on each side, viz., from without 

 inwards, 1, the fovea inguinalis lateralis, on the outer side of the plica epigastrica,

 inguinalis mesialis between the plica epigastrica and the plica hypogastrica ; and 

 3, the fovea supravesicalis, between the plica hypogastrica and plica urachi, 

 immediately above and external to the apex of the bladder. Of these, the fovea 

 inguinalis mesialis is the most strongly marked, and often extends inwards for some
