There are but five pads of the border series instead of the 

 typical six, the reduction in number being apparently due to 

 fusion of Th and I. Pad H is constricted transversely, H d 

 and H p being thus separated. The pads are not markedly 

 elevated. A distinctive feature of the palm is the presence 

 of numerous patches of ridge-bearing skin, ranging in diam- 

 eter up to several millimeters, intermingled with much more 

 minute " epidermal rings" (Whipple). It is of interest to 

 note that three patches of ridged skin, larger than those 

 found in any other area, occur in the positions 2 P , 3 P and 4 P . 

 Notwithstanding the discontinuity of ridged skin, the gen- 

 eral courses of ridges follow common directions, hence admit- 

 ting tracings such as those shown in the figures.

As in the palm, pads are somewhat flattened. The same 

 series of border pads is recognizable, with a suggestion of 

 separation of H d and H p , and a distinct division of Th d and 

 Th p . 



The central area corresponds to that of the palm in pre- 

 senting a mingling of ridged patches and epidermal rings. In 

 several soles this condition extends even into the territories 

 of border pads, involving particularly H and Th.
