DESCRIPTIONS OF THE PAPILLARY RIDGES 71 



in lateral folding of the organ. This particular feature of the 

 anthropoids does not develop so highly in man, though it is 

 present on certain parts of the palm. It is remarkably absent 

 on nearly all the sole of man's foot, as might be expected from 

 its function. Indeed, one generahsation follows from the 

 examination of this series of hands and feet, viz., that the 

 complexity of pattern in the different regions, digital, palmar 

 and plantar, is in close correspondence with the activity of 

 function of the part. Thus the palm and sole of the Baboons 

 compared with the digits, the digits of the Gibbon with the 

 palm and sole, the terminal phalanges of man compared with 

 any other region of any other species, bear out this statement 

 very fully, and many other illustrations may be gathered from 

 this series of drawings.
