superficial pubic, to the jietedag the superficial epigastric; and the enternal 
circumflex ilu, to the skin about the crest of the ilium. 
b. The profunda. This, the largest branch of the femoral, arises about 
two inches below the crural arch, from the outer and back part of the femo- 
ral artery, and descends behind it. At the back part of the thigh it termi- 
nates in two branches for the hamstring muscles, and in its course gives off 
the two circumflex, and the three perforating arteries. The external cir- 
-cumflex arises from the outer part of the profunda, and, passing transversely 
beneath the sartorius and rectus muscles, divides into three fasciculi of 
branches. The internal circumflex arises near the preceding, sometimes from 
the femoral itself, and passes to the back part of the thigh. The /irst, or supe- 
‘rior perforating artery, passes backwards beneath the lesser trochanter to the 
adductor magnus and to the hamstring muscles. The second, or middle 
perforating artery, passes through the adductor magnus and brevis to the 
muscles on the back of the thigh. The third, or inferior perforating artery, 
‘descends behind the adductor longus to the hamstrings. . On the back part 
of the thigh the profunda ends in two branches, of which one passes to the 
biceps, the other to the semi-membranosus. 
c. After the origin of the profunda, the femoral gives off several small 
twigs, and near the opening in the triceps it gives off a third, the anastomo- 
tica magna, whiah descends in front of the adductor tendon to the knee, 
and sends several branches to the integuments, vastus externus, and to the 
patella. 
4, THE PoPLIT#AL*ARTERY descends from the inner side of the femur, 
outwards to the inferior and central part of the popliteal space. Its branches 
are: 1. Several muscular branches to the hamstrings, and to the gastrocne- 
mius; 2. Superior articular, which encircle the lower extremity of the femur, 
and communicate with the anastomotica; 3. Azygos articular, passing for- 
wards through the posterior ligament of the joint to the synovial membrane, 
and the ieee substance in its cavity ; 4. Inferior articular arteries, aitich 
encircle the lower part of the joint to its fore part, and inosculate ain the 
preceding, and with the anterior tibial recurrent. At the lower part of the 
ham the popliteal divides into the anterior and posterior tibial arteries. 
5. THe ANTERIOR TIBIAL ARTERY perforates the interosseous space close 
to the head of the fibula, descends along the interosseous membrane, and 
over the lower part of the tibia, to the first interosseous space. It gives off: 
1. The recurrent to the articulation of the knee; 2. Muscular branches to the 
muscles on the outer and anterior part of the leg; 3. Malleolar branches to 
the internal and external malleoli; 4 and 5. Zarsal and metatarsal; between 
the two first metatarsal bones it divides into, 6, the anterior pollicis to the 
integuments, and 7, communicans to the first interosseal muscles. 
6. Tue Posterior TrBIAL ARTERY descends between the superficial and 
deep layer of muscles on the back of the leg, to the space between the heel 
and inner ankle, where it divides into the external and internal plantar 
arteries. It gives off: 1. Several muscular branches; 2. The peroneal 
artery. This arises about an inch below the popliteal, and, descending to 
the ankle, divides into the anterior and posterior peroneal branches. The
