atements 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 manners and customs
of adult anthropoids of this species, in their native woods, was almost
wanting up to the time of the publication of the paper by Dr. Savage,
to which I have already referred; containing notes of the observations
which he made, and of the information which he collected from sources
which he considered trustworthy, while resident at Cape Palmas, at the
north-western limit of the Bight of Benin.

The adult Chimpanzees measured by Dr. Savage, never exceeded, though the
males may almost attain, five feet in height.

"When at rest, the sitting posture is that generally assumed. They
are sometimes seen standing and walking, but when thus detected,
they immediately take to all fours, and flee from the presence of the
observer. Such is their organization that they cannot stand erect, but
lean forward. Hence they are seen, when standing, with the hands clasped
over the occiput, or the lumbar region, which would seem necessary to
balance or ease of posture.

"The toes of the adult are strongly flexed
