RIGHT FOOT OF A LEMUR 
In this low form of monkey the friction-skin is well developed, but the patterns which char- 
acterize the higher apes and man have not yet appeared. In the place of the well-known 
loops, arches and whorls, the lemur'’s finger-tips are seen to be marked only by longitudinal 
ridges. Photograph by Gertrude Sullender. (Fig. 14.)
