THE CHIMPANZEES. 203 



Koppenfels had affirmed he had shot such cross-bred animals. 

 It is still an undecided question to what species it belonged. 



Of the four genera of the Simiidce, " the Gibbons are ob- 

 viously most remote from Man, and nearest to the Cyitopitheci^ii 

 ( CercopithecidcB) . 



"The Orangs come nearest to Man in the number of the 

 ribs, the form of the cerebral hemispheres, the diminution of 

 the occipito-temporal sulcus [groove] of the brain, and the ossi- 

 fied styloid process; but they differ from him much more 

 widely in other respects, and especially in the limbs, than the 

 Gorilla and the Chimpanzee do. 



" The Gorilla is more Man-like in the proportions of the leg 

 to the body, and of the foot to the hand ; further, in the size 

 of the heel, the curvature of the spine, the form of the pelvis, 

 and the absolute capacity of the cranium. 



"The Chimpanzee approaches Man most closely in the 

 character of its cranium, its dentition, and the proportional size 

 of the arms." {Huxley.) 



THE HUMAN RACE. FAMILY HOMINID^. 



With this family we reach the culminating point of the 

 zoological tree. It contains but one monotypic genus. Homo, 

 with its single species. Homo sapiens. Although deriving his 

 specific designation from the unique characteristic of his mental 

 attributes, Man comes under review here alone in his physical 

 aspect as one of the mammalian animals. 



" Identical in the physical processes by which he originates 

 — identical in the early stages of his formation — iden- 

 tical in the mode of his nutrition before and after birth 

 with the animals which lie immediately below him on the
