e same excellent observer, from whom I have borrowed the preceding
account of the habits of the adult Chimpanzee, published an account of
the Gorilla, which has, in its most essential points, been confirmed
by subsequent observers, and to which so very little has really been
added, that, in justice to Dr. Savage, I give it almost in full:

"It should be borne in mind that my account is based upon the
statements of the aborigines of that region (the Gaboon). In this
connection it may also be proper for me to remark that, having been a
missionary resident for several years, studying, from habitual
intercourse, the African mind and character, I felt myself prepared to
discriminate and decide upon the probability of their statements.
Besides, being familiar with the history and habits of its interesting
congener (_Trogniger_, Geoff.), I was able to separate their accounts
of the two animals, which, having the same locality and a similarity
of habit, are confounded in the minds of the mass, especially as but
few--such as traders to the interior, and huntsmen--have ever seen the
animal in question.

"The tribe from which our knowledge of the animal is derived, and
whose territory forms its habitat, is the _Mpongwe_, occupying both
banks of the River Gaboon, from its mouth to some fifty or sixty miles
upward....

"If the word 'Pongo' be of African origin, it is probably a corruption
of the word _Mpongwe_, the name of the tribe on the banks of the
Gaboon, and hence applied to the region they inhabit. Their local name
for the Chimpanzee is _Enche-eko_, as near as it can be Anglicized,
from which the common term 'Jocko' probably conies. The _Mpongwe_
apellation for its new congener is _Enge-ena_, prolonging the sound of
the first vowel, and slightly sounding the second.

"The habitat of the _Enge-ena_ is the interior of Lower Guinea, while
that of the _Enche-eko_ is nearer the seaboard.

"Its height is about five feet; it is disproportionately broad across
the shoulders, thickly covered with coarse black hair, which is said
to be similar in its arrangement to that of the _Enche-eko_; with age
it becomes gray, which fact has given rise to the report that both
animals are seen of different colors.

"Head.--The prominent features of the head are the great width and
elongation of the face, the depth of the molar region, the branches of
the lower jaw being very deep and extending far backward, and the
comparative smallness of t
