a, the iliac cresl ; b, the great 

 sacro-sciatic ligament attached to 

 the tuberosity of the ischium ; c, 

 great trochanter ; d, the integu- 

 ment close to the anus ; c, great 

 sciatic nerve ; f, the line from this 

 letter crosses the tendons of the 

 inner hamstring muscles ; g, head 

 of the fibula ; 1, gluteal artery ; 

 2, pudic ; 3, sciatic artery, giving 

 its branches to the short external 

 rotator muscles, to the sciatic 

 nerve, and to the upper part of 

 the long flexor muscles ; 4, first 

 perforating artery; 4', its branches 

 to the flexor muscles ; 5, branches 

 of the second perforating ; 6, 

 branches of the third perforating; 

 7, popliteal artery, near this the 

 origin of the superior muscular 

 branches; 8, placed on the ten- 

 don of the adductor magnus near 

 the origin of the superior articular 

 branches ; 9, the anastomosis of 

 the external superior articular 

 with other branches ; 10,thesural 

 branches ; 11, the recurrent of 

 the anterior tibial artery. 



the femoral artery : their size 

 appears to bear an inverse 

 proportion to that of the 

 descending branches of the 

 external circumflex artery. 



IV. ANASTOMOTIC ARTERY. 

 Close to its termination 

 the femoral artery gives off 

 a branch, canstaut but of 

 moderate size, named the 

 anastomotic artery (anastomo- 

 tica magnet), which descends 

 in the same line as the femoral 

 artery itself (see fig. 298). 

 Arising from that vessel when 

 about to enter the popliteal 

 space, it descends upon the 

 tendon of the adductor mag- 

 nus to the inner coudyle of 

 the femur, giving off several 

 branches, and covered by some 

 it finally anastomoses with the
