 unlike anything found in typical mammals that even the location 

 in the human subject of these once important eminences, with 

 their associated patterns, is by no means a simple matter. The

best aid here comes from the comparison of the human foot 

 with that of some one of the large Anthropoids, preferably a 

 Chimpanzee (Fig. 22), where both the thenar and hypothenar 

 are still evident, although the drawing-out process has already 

 commenced. The backward extension seems here to involve 

 mainly the hypothenar region, and as this surmise is supported 

 by the relation of the underlying skeletal parts, we may look upon 

 the entire human sole, back of the " ball of the foot," i. e., the inter- 

 digital pads, as an extended hypothenar. The thenar seems to 

 take no part in the extension, but lies passively upon the medial
