extended from the median line, would ill support the fore-part 

 of his body ; the great indented muscle which, in quadrupeds, 

 suspends the trunk between the blade-bones as a girth, is 

 smaller in Man than in any one among them ; the head is 

 heavier, on account of the magnitude of the brain, and the 

 smallness of the sinuses or cavities of its bones ; and yet the 

 means of supporting it are weaker, for he has neither cervical 

 ligament, nor are the vertebrae so modified as to prevent their 

 flexure forward ; he could, therefore, only maintain his head in 

 the same line with the spine, and then, his eyes and mouth 

 being directed towards the ground, he could not see before 

 him." {Cuvler.) 



The breadth of the sacrum is equal to or exceeds its length, 

 and the width of the pelvis exceeds its height, the reverse of 

 what is seen in Apes. The wrist {carpus) in Man has no central 

 bone ; the ankle {tarsus) is longer than the metatarsal segment, 

 and that is again longer than the toe-bones, which are more 

 compressed than the finger-bones. In Man the teeth form a 

 continuous series — there is no diastema, which, with the excep- 

 tion of the extinct Anoplotherium^ is alone true of Man ; his 

 canine teeth are never prominent or tusk-like. 



The human brain differs from that of the Man-like Apes in 

 regard to its convolutions and their separating grooves, only in 

 minor characters ; but in weight, as in capacity, very greatly 

 The weight of a healthy full-grown human brain never descends 

 below thirty-two ounces, that of the largest Gorilla, far heavier 

 than any Man, never attains to more than twenty. Yet, " the 

 difference in weight of brain between the highest and the 

 lowest Men is far greater relatively and absolutely than between 

 the lowest Man and the highest Ape." {Huxky.) 



Notwithstanding the enormous differences presented between
