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
