chimpanzee are, as Huxley well puts it, much less than 

 those between the chimpanzee and lower quadrumana, 

 as lemurs, etc. In fact, man is the type of a family, 

 Hominidae, of the order Quadrumana, as indicated by 

 the characters of the dentition, extremities, brain, etc. 

 The reader who may have any doubts on this score may 

 read the dissections of Geoffrey St. Hilaire, made in 

 1856, before the issue of Darwin's Origin of Species. 

 He informs us that the brain of man is nearer in struc- 

 ture to that of the orang than the orang's is to that of 

 the South American howler, and that the orang and 

 howler are more nearly related in this regard than are 

 the howler and the marmoset 



The modifications presented by man have, then, re- 

 sulted from an acceleration in development in some 

 respects, and retardation perhaps in others. But until 

 the combination now characteristic of the genus Homo 

 was attained the being could not properly be called man. 



And here it must be observed that as an organic type 

 is characterized by the coexistence of a number of pe- 

 culiarities which have been developed independently of 

 e-ach other, its distinctive features and striking functions 

 are not exhibited until that coexistence is attained which 

 is necessary for these ends. 



Hence, the characters of the human genus were prob- 

 ably developed successively ; but few of the indications 

 of human superiority appeared until the combination 

 was accomplished. Let the opposable thumb be first 

 perfected, but of what use would it be in human affairs 

 without a mind to direct ? And of what use a mind 

 without speech to unlock it ? And speech could not be 

 possible though all the muscles of the larynx but one 

 were developed, or but a slight abnormal convexity in 

 pne pair of cartilages remained,
