altogether rave in man. Bischoff and others have 

 justly maintained that the resemblance to man which 

 is found in these animals in the arrangement of the 

 heart and larger blood-vessels appears to be con-

 habits are arboreal, this very fact implies that they 

 are for the most part in an upright position. 



The division of the femoral arteries displays a 

 somewhat interesting deviation from the normal 

 human type. High up near the femoral arch an 

 artery, accompanied by veins and a large nerve, 

 diverges from the femoral artery, which extends, 

 together with its accompanying parts, as far as the 

 back of the foot. In the gorilla this branch pierces 

 the sartorius.
