Hepburn — The Papillary Ridges on the Hands and Feet of Monkeys and Men. 537 



With regard to the nature of the patterns found in the different feet under 

 consideration, I think they are fully accounted for by the shape and size of the 

 particular elevations on which they may be found. Further, the sub-division of 

 the sole of the human foot into two areas, in each of which the papillary ridges 

 possess a characteristic disposition, seems to me to be intimately associated with 

 its evolution in its transition from an organ in which the prehensile function 

 predominates, to one in wliich it principally serves the purposes of an organ of 

 support.
