Takeya, '33), one digit removed from the place in the digital 

 sequence of the index finger, which presents the maximum 

 concentration of radial loops. While no studies of the correla- 

 tion have been made in the same sample, it is significant that 

 statistics on the frequencies of finger-print types indicate 

 that digits IV of the hand and III of the foot, the centers 

 of maximal representation of hair, are also the sites of greatest 

 frequency of whorls. We have translated Newman's records 

 of the percentile frequencies of pattern types into pattern 

 intensities (fig. 599A). The result shows a nearly exact agree- 

 ment of digits II through V in the hand with I through IV in 

 the foot. The thumb and little toe can not be partnered as was 

 done in other comparisons of digits, since they represent 

 respective elevation and depression of pattern intensity. 



It is emphasized above that in both palm and sole the 

 characteristic site of minimum pattern intensity in the inter- 

 digital areas of non-human primates is interdigital III, the 

 configurational field which lies in the anatomical axis in both 

 members. In man the unlike axes of hand and foot are as- 

 sociated with unlike foci of lessened pattern intensity. Inter- 

 digital II in the palm and IV in the sole possess the actual 

 minimal intensities of these members, recalling the compara- 

 ble relations of digital length and hair occurrence in marginal 

 digits. The findings suggest that factors other than axial 

 position may lessen pattern intensity. Considering the remain- 

 ing two areas in each member, III and IV in the hand and II 

 and III in the foot, the principle previously stated in reference 

 to non-human primates still holds; of these two areas in the 

 foot the lesser intensity is that of interdigital II, which is in 

 the anatomical axis, and in the hand it is likewise the area 

 in the axis, here interdigital III. 



Again in man there occur at the distal plantar margin and 

 at the distal palmar margin variations which are differently 

 localized in foot and hand. To appreciate these variations, 

 there should be noted (figs. 587-593) the characteristic digital 

 triradii, seated just proximal to the bases of digits II- V. In 

 the sole there is a tendency, most frequently expressed in rela-
