MAN AND APES. 137 



rather be conceded to the regulating and co- 

 ordinating apparatus by means of which the 

 tensions are so varied and directed as to 

 produce harmonious and consentient results. 

 But this supremacy is still further manifest 

 when we consider that the very integrity of 

 these structures is maintained, and their 

 repair effected, by the agency of that very 

 same co-ordinating apparatus which is the con- 

 troller of animal life, the lord of all within its 

 own boundaries, and which says to every other 

 system of parts, " Starve thou before me." 



This supreme and dominant apparatus is 

 the nervous system. The ape, which has this 

 system — and especially the dominant part of 

 this dominant system, namely, the brain — 

 most in conformity with the same system in 

 man, must surely be held to be the most 

 materially man-like in structure. 



Now, it is not the Chimpanzee, certainly 

 not the Gorilla nor yet the Gribbons, which 

 most resemble man as regards his brain. In 

 this respect the Orang stands highest in rank.
