nt from any of these that he concludes them to
be specifically distinct; they were respectively 3 feet 8 1/2 inches
and 3 feet 9 1/2 inches high, and possessed no sign of the cheek
excrescences, but otherwise resembled the larger kinds. The skull has
no crest, but two bony ridges, 1 3/4 inches to 2 inches apart, as in
the 'Simia morio' of Professor Owen. The teeth, however; are immense,
equalling or surpassing those of the 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 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 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 would be still less reason for doubting
its occasional adoption of the upright attitude or of aggressive
proceedings.

From the time of Tyson and Tulpius downwards, the habits of the young
CHIMPANZEE in a state of captivity have been abundantly reported and
commented upon. But trustworthy evidence as to the
