THE MAN-LIKE APES. 55 



other species. The females of both these kinds, according 

 to Mr. Wallace, are devoid of excrescences, and resemble 

 the smaller males, but are shorter by 1^ to 3 inches, and 

 their canine teeth are comparatively small, subtruncated 

 and dilated at the base, as in the so-called Simia morio, 

 which is, in all probability, the skull of a female of the 

 same species as the smaller males. Both males and fe- 

 males of this smaller species are distinguishable, according 

 to Mr. Wallace, by the comparatively large size of the 

 middle incisors of the upper jaw. 



So far as I am aware, no one has attempted to dispute 

 the accuracy of the statements which I have just quoted 

 regarding the habits of the two Asiatic man-like Apes ; 

 and if true, they must be admitted as evidence, that such 

 an Ape — 



lstly, May readily move along the ground in the erect, 

 or semi-erect, position, and without direct support from 

 its arms. 



2ndly, That it may possess an extremely loud voice, so 

 loud as to be readily heard one or two miles. 



3rdly, That it may be capable of great viciousness and 

 violence when irritated : and this is especially true of 

 adult males. 



4thly, That it may build a nest to sleep in. 



Such being well-established facts respecting the Asiatic 

 Anthropoids, analogy alone might justify us in expecting 

 the African species to offer similar peculiarities, separately 

 or combined ; or, at any rate, would destroy the force of 

 any attempted a priori argument against such direct testi- 

 mony as might be adduced in favour of their existence. 

 And, if the organization of any of the African Apes could 

 be demonstrated to fit it better than either of its Asiatic 

 allies for the erect position and for efficient attack, there
