dorso-lumbai vertebrae. There is 

 no os centrale in the carpus. They 

 live in families in the forest, and 

 feed on fruits. As regards size, 

 the gorillas are most like man. 

 The males are much larger than 

 the females. 



The Chimpanzees (Anthropo- 

 pithecus) live in Western and 

 Central Equatorial Africa. They 

 do not exceed a height of 5 ft. 

 The arms reach a little below the 

 knee. They walk on the backs 

 of their closed hands and on their 

 soles or closed toes. The skull 

 has no high crests. The supra- 

 orbital ridges are distinct. The 

 canines are smaller than in gorilla 

 or orang. There is no centrale 

 in the carpus. There are vocal 

 sacs. The chimpanzees live in 

 families in the forest, and are 

 chiefly arboreal, making nests in 

 trees. They seem to feed on 

 fruits. In the sigmoid curvature 

 of the vertebral column the chim- 

 panzees are most like man. 



In connection with the an- 

 thropoid apes may be noticed 

 Pithecanthropes erectus, a new 

 genus erected by Dubois from the 

 top of a skull, some teeth, and a 

 femur found by him (fossil) in Java, 

 and believed to represent a form 

 intermediate between man and the 

 Anthropoid apes.
