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

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

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

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
