170 MAN AND APES. 



by the true apes. Thus, the typical Lemurs 

 and the Inclris have a more completely 

 opposable and better developed thumb than 

 any ape. In the slender Loris we find an 

 absence of the extra interlocking processes 

 (metapophyses and anapophyses) of the back 

 bone, the spinous processes of which do not 

 converge (fore and aft) towards a central 

 point; the pisiform bone of the wrist is 

 smaller than in any ape; the proportion 

 borne by the thumb to the hand in length is 

 more human, as is the form assumed by the 

 ischium, and the relative size of the foot 

 compared with the leg. In the Indrisince 

 and in Lepilemur we find but eight carpal 

 bones (a character found in no other Primates 

 save man, the Chimpanzee and Gorilla), and 

 the most human proportional length of both 

 the thumb and the index finger compared 

 with the length of the spine. We also find 

 in the short-tailed Indris the length of the 

 femur compared with that of the haunch-bone 

 most human, as also the length of the foot
