116 MAN AND THE LOWER ANIMALS. n

 ber and in form. The molars acquire, more and 

 more, a many-pointed, insectivorous character, and 

 in one Genus, the Aye- Aye (Cheiromys), the ca- 

 nines disappear, and the teeth completely simulate 

 those of a Eodent (Fig. 18). 



Hence it is obvious that, greatly as the denti- 

 tion of the highest Ape differs from that of Man, 

 it differs far more widely from that of the lower 

 and lowest Apes. 



Whatever part of the animal fabric — whatever 

 series of muscles, whatever viscera might be se- 

 lected for comparison — the result would be the 

 same — the lower Apes and the Gorilla would dif- 

 fer more than the Gorilla and the Man. I can- 

 not attempt in this place to follow out all these 

 comparisons in detail, and indeed it is unnecessary 

 I should do so. But certain real, or supposed, 

 structural distinctions between man and the apes 

 remain, upon which so much stress has been laid, 

 that they require careful consideration, in order 

 that the true value may be assigned to those which 

 are real, and the emptiness of those which are 

 fictitious may be exposed. I refer to the char- 

 acters of the hand, the foot, and the brain. 



Man has been defined as the only animal pos-

 been said that all the apes possess four hands; and
