brain of man as well as of the ape in the denial of 

 which Owen cut such a sorry figure, Huxley adds : 



' So far as cerebral structure goes, therefore, it is 

 clear that Man differs less from the Chimpanzee or 

 the Orang than these do even from the Monkeys, and 

 that the difference between the brains of the Chim- 

 panzee and of Man is almost insignificant when com- 

 pared with that between the Chimpanzee brain and 

 that of a Lemur. . . . Thus, whatever system of 

 organs be studied, the comparison of their modifi- 

 cations in the ape series leads to one and the same 

 result, that the structural differences which separate 

 Man from the Gorilla and the Chimpanzee are not so 

 great as those which separate the Gorilla from the 

 lower apes. But in enunciating this important truth 

 I must guard myself against a form of misunder- 

 standing which is very prevalent . . . that the 

 structural differences between man and even the 

 highest apes are small and insignificant. Let me 

 then distinctly assert, on the contrary, that they are 

 great and significant ; that every bone of a Gorilla 

 bears marks by which it might be distinguished from 

 the corresponding bone of a Man ; and that, in the 

 present creation, at any rate, no intermediate link 

 bridges over the gap between Homo and Troglodytes. 

 It would be no less wrong than absurd to deny the 

 existence of this chasm ; but it is at least equally 

 wrong and absurd to exaggerate its magnitude, and, 

 resting on the admitted fact of its existence, to 

 refuse to inquire whether it is wide or narrow. 

 Remember, if you will, that there is no existing link 

 between Man and the Gorilla, but do not forget that 

 there is a no less sharp line of demarcation, a
