ever, is affirmed to be hoarse,
guttural, and not very loud, somewhat like "whoo-whoo." (l. c. p. 365).

The analogy of the Chimpanzee to the Orang, in its nest-building habit
and in the mode of forming its nest, is exceedingly interesting; while,
on the other hand, the activity of this ape, and its tendency to bite,
are particulars in which it rather resembles the Gibbons. In extent of
geographical range, again, the Chimpanzees--which are found from Sierra
Leone to Congo--remind one of the Gibbons, rather than of either of the
other man-like apes; and it seems not unlikely that, as is the case with
the Gibbons, there may be several species spread over the geographical
area of the genus.

The same excellent observer, from whom I have borrowed the preceding
account of the habits of the adult Chimpanzee, published fifteen years
ago, [24] 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 ('Trog. niger',
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 comes. The Mpongwe appellation f
