AS APPLIED TO MAN. 343 



it have been of the men whose sole weapons were 

 rudely chipped flints, and some of whom, we may 

 fairly conclude, were lower than any existing race ; 

 while the only evidence yet in our possession shows 

 them to have had brains fully as capacious as those 

 of the average of the lower savage races. 



We see, then, that whether we compare the savage 

 with the higher developments of man, or with the 

 brutes around him, we are alike driven to the con- 

 clusion that in his large and well-developed brain 

 he possesses an organ quite disproportionate to his 

 actual requirements an organ that seems prepared in 

 advance, only to be fully utilized as he progresses in 

 civilization. A brain slightly larger than that of the 

 gorilla would, according to the evidence before us, 

 fully have sufficed for the limited mental development 

 of the savage; and we must therefore admit, that the 

 large brain he actually possesses could never have 

 been solely developed by any of those laws of evolu- 

 tion, whose essence is, that they lead to a degree of 

 organization exactly proportionate to the wants of 

 each species, never beyond those wants that no pre- 

 paration can be made for the future development of 

 the race that one part of the body can never increase 

 in size or complexity, except in strict co-ordination to 

 the pressing wants of the whole. The brain of pre- 

 historic and of savage man seems to me to prove 

 the existence of some power, distinct from that which 

 has guided the development of the lower animals 

 through their ever- varying forms of being.
