on its palin are transverse, and not oblique. There are also 



radiating grooves, commencing at the carpal end of the palm. 



d. The human hand and the hand of the ape are not only 



hands when viewed morphologically, but 



they are also hands when considered from 



the teleological point of view. 



e. The human foot and the ape's foot 

 are morphologically feet, but the human 

 foot is not only morphologically but teleo- 

 logically a foot ; and, moreover, the only 

 perfect and complete foot, whereas the 

 ape's foot is teleologically a hand. The 

 metatarso-phalangeal joints of the human 

 foot all incline outwards from the great 

 toe, due to the direction of the pressure 

 upon them. This outward inclination 

 gives breadth to the foot. In the foot of 

 the ape the metatarso-phalangeal joints 

 all incline in the 

 same direction 

 as the metacarpo- 

 phalangeal joints in its hand. The 

 foot is consequently clenched like a 

 fist. In the sole of the human foot 

 there is a great longitudinal groove, 

 commencing in front of the heel-pad, 

 which is the tegumentary indica- 

 tion of the double-columned arrange- 

 ment. In the sole of the ape there 

 is a longitudinal groove which comes Flg ' 10 ' , , ±
