The Iliac Artery, II., PI. 9, and fig. 3, PI. 10, arises from 

 the aorta just anterior to the posterior extremity. It runs out- 

 ward and backward along the inner surface of the body wall un- 

 til it reaches a point directly above the ischium, where it divides 

 into three main branches. The most anterior, the Epigastric 

 Artery, Epi., PI. 9, and fig. 3, PL 10, runs cephalad and anas- 

 tomoses with the cutaneous ; it gives off a small branch, Epi. R., 

 fig. 3, PI. 10, to the rectus femoris and one to the body wall, 

 Epi. B., fig. 3, PI. 10. The middle and main branch is the 

 Femoral Artery, Fi\, PI. 9, and fig. 3, PL 10, which directly 

 continues the iliac. It crosses the ventral surface of the ischium 

 and at its posterior border gives off a branch which immediately 

 divides into three small branches. The most anterior of these, 

 Er. c, fig. 3, PL 10, runs around the head of the femur and con- 

 tinues between the rectus femoris and the sartorius ; it breaks 

 up in the flexor digitorum communis and sends a branch to the 

 first digit. The second of these three branches, Fr. b., fig. 3, 

 PL 10, runs under the rectus femoris and continues beneath the 

 skin of the fore leg to the last digit. The third and most pos- 

 terior branch, Fr. a., fig. 3, PL 10, goes to the sacro-plantaris 

 muscle. 



The femoral itself continues along the postero-dorsal surface 

 of the upper half of the gracilis, crosses the femur diagonally to 

 its anterior surface and continues between the gracilis and sar- 

 torius muscles. On the inner surface of the fore leg, between 

 the tibia and fibula, it gives off several branches, one to the flexor 

 tarsi tibialis, C. a., fig. 3, PL 10, which is continued to the first 

 digit, one to the flexor tarsi fibularis, which is continued to the 

 last digit, C. b., fig. 3, PL 10, one to the flexor and one to the 

 extensor digitorum communis. The femoral then runs between 

 the cartilages of the tarsus to the dorsal side of the foot, where 

 it breaks up into three branches. The first of these goes to the 

 adjacent sides of the first and second digits, the second to the ad- 

 jacent sides of the second and third digits, and the third goes to 

 the adjacent sides of the third and fourth digits. 



The third branch of the iliac, the Vesical Artery, Vs., PL 

 9, Vsc, fig. 3, PL 10, arises just before the iliac pierces the body
