both these kinds, according to Mr. Wallace, are devoid of excrescences,
and resemble the smaller males, but are shorter by 1 1/2 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 females 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--

Firstly, May readily move along the ground in the erect, or
semi-erect, position, and without direct support from its arms.

Secondly, That it may possess an extremely loud voice, so loud as to
be readily heard one or two miles.

Thirdly, That it may be capable of great viciousness and violence
when irritated: and this is especially true of adult males.

Fourthly, 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 testimony as might be adduced in favour of their
