Saphenous opening. — The depression corre.^^ponding to this is placed just 

 below Giiubernat".s ligament, with which its upper extremity blends. Its centre is 

 about an inch and a half (37 mm.) below and al.^o external to a line dropped ver- 

 tically from the pul)ic .spine. This and the other structures concerned in femoral 

 hernia are fully descril)ed under this section (ride .<<iij,ra, ])age 113H).

anterior superior spine and the symi)hysis pubis to the adductor tubercle will 

 correspond with the course of this vessel. The sartorius usually crosses it, three 

 to four inches (100 mm.) below Poupart's ligament. The profunda artery arises 

 an inch and a half to two inches below Poupart's ligament. Therefore the incision 

 for tying the femoral in Scarpa's triangle should be al»out three inches long, in 

 the line of the artery, and begin about three inches below Poupart's liganu-nt. and 

 run over the apex of the triangle. The vein lies, below Poujiart's ligament, imme- 

 diately to the inner side of the artery. From tliis ])oint the vein gt'ts on to a .some- 

 what deeper plane, though still very close to the artery, and gradually inclining back-
