The Destiny of Man. 29 



and its complexity of structure increased 

 a thousand-fold, while in other respects his

 hands to be devoted entirely to prehension 

 and thus relieving the jaws of that part of 

 their work, has cooperated in producing 

 that peculiar contour of head and face 

 which is the chief distinguishing mark of

 changes derive their importance entirely 

 from the prodigious intellectual changes 

 in connection with which they have been 

 produced ; and these intellectual changes 

 have been accumulated until the distance, 

 psychically speaking, between civilized man 

 and the ape is so great as to dwarf in com-
