Femoral artery. As in the H<.r.- . this gives off: 1, Several muscular innomiimi- 

 ; 2, Two tjn'tif Hi'iKcular arteries, the posterior of which furnishes tho prepubic 

 tuii nj : 3, A (/>/ nl lirnwli. 



In the, Hitrli, the i j-i, run] /milic artery, emanating from the prepubic division, presents 

 some peculiarities in its distribution : it gives oft" a long branch which is placed in the 

 texture t' tin- niaiumic, and passes forward to meet and uuite with the mammary branch 

 furnished by tlie internal thoracic artery; it then runs between the two thighs in a 

 flexuous manner, and reaches the lips of the vulva, where it ends in numerous minuscules 

 that anastomose with the vnlvulnr divisions of the internal pudic artery. 



The *((/.-/</ an arti ry is as remarkable for its largo volume as for its destination. It 

 di .-<, nils on the internal face of the leg, furnishing numerous subcutaneous divisions. 

 and terminates at the hock by several slender iHnntur twiijx, which accompany the flexor 

 tendons. Among the branches given off by this vessel in its course, it is neee.-sary to 

 distinguish two: one which follows the anterior branch of the ^aphena vein to the 

 hock, where it communicates by its terminal divisions with the tarsal artery ; the other 

 arises a little lower, passes beneath the phalangeal flexor muscles, and is expended on the 

 hock in articular and malleolar branches. In the latter branch we see a trace of the 

 )nn,ml (irtinj (if Man. The saphena itself, considered as a whole, and particularly 

 towards its inferior moiety, supplements the posterior tibinl artery. 



Popliteal artery. This artery gives an important femoro-popliteal branch, and enters 

 the tibio-peroneal arcade to constitute the anterior tibial artery, after distributing on 

 its course musculnr rnmuscules rudiments of the posterior tibial artery of other animals. 



The antt-rior til>fal artery, arriving in front of the hock, detaches the tanal artery. 

 a voluminous branch divided near its origin into several superficial superior and inferior 

 branches. It continues to descend, traverses from before to behind the superior part of 

 the third intermetatarsal space, and terminates by an arterial arcade situated beneath 

 the flexor tendons; from this arcade emanate ascending divisions, which anastomose 

 with the plantar arteries, and three large descending or digital branches, which affect the 

 same disposition as three analogous principal arteries emanating from the superficial 

 palmar arcade of the anterior limb. 



COMPARISON OP THE EXTERNAL ILIAC3 OF MAN WITH THOSE OF ANIMALS. 



In Man, the external iliac forms the external branch of the bifurcation of tho 

 common iliac ; it extends to the crurnl arch, where it lakes the name of femoral art> nj. 

 It furnishes the circnmflcxa ilii and epigastric: the latter resembling, in its distribution, 

 the posterior abdominal branch given off by the prepubic artery in the Horse. 



The femoral artery has the same general disposition as in animals, and almost the 

 same collateral branches. There is no prepubic artery ; the divisions furnished by this 

 trunk in Solipeds originate separately from the femoral artery; these are: the itMomhinl 

 I'ljniH' nfiil artery (superficial epigastric), and the external pudic arteries tip ^iie n - 

 i iiir the subcutaneous abdominal artery, and the others the branches of the external 

 pudic artery of animals. 



The p<>i>liteal artery is a superficial vessel situated at the posterior face of the knee- 

 joint, in a lozenge-shaped space limited by the nni-ch s of the region, and named tho 

 ;*./,/// <// njtace. At the libio-peroneal arch it bifurcates, and constitutes the anterior 

 tib''al and the tibio-peroneal trunks. 



The h'liin-i mural trunk does not exist in animals in which the peroneal artery 



is in a rudimentary state, in consequence of the feeble development of the pcronens. 



This trunk is short, and furnishes the nutrient artery of the til.ia. th- n divides into tho 



ptron"il and j*>:t<ri<>r tiltial arteries. The first descends t<> the external malleolus, 



along the inner face of tho tibia, and terminate* in two brandies, one of which, tho 



!. communicates with the dornal artery of the tar.-ns n branch of the 



].-(i;il. Tho posterior tibial, on reaching the concavity of the calcis, constitutes tho 



./<i/ plantar arteri'*. The inlrrnul pliutnr is directed forwards, U-neath
