and Orang', in the 'Zoological Transactions'--a memoir which,
by the accuracy of its descriptions, the carefulness of its comparisons,
and the excellence of its figures, made an epoch in the history of our
knowledge of the bony framework, not only of the Chimpanzee, but of all
the anthropoid Apes.

By the investigations herein detailed, it became evident that the old
Chimpanzee acquired a size and aspect as different from those of the
young known to Tyson, to Buffon, and to Traill, as those of the old
Orang from the young Orang; and the subsequent very important researches
of Messrs. Savage and Wyman, the American missionary and anatomist, have
not only confirmed this conclusion, but have added many new details.

One of the most interesting among the many valuable discoveries made by
Dr. Thomas Savage is the fact, that the natives in the Gaboon country at
the present day, apply to the Chimpanzee a name--"Enche-eko"--which is
obviously identical with the "Engeko" of Battell; a discovery which has
been confirmed by all later inquirers. Battell's "lesser monster" being
thus proved to be a veritable existence, of course a strong presumption
arose that his "greater monster," the 'Pongo,' would sooner or later
be discovered. And, indeed, a modern traveller, Bowdich, had, in 1819,
found strong evidence, among the natives, of the existence of a second
great Ape, called the 'Ingena,' "five feet high, and four across the
shoulders," the builder of a rude house, on the outside of which it
slept.

In 1847, Dr. Savage had the good fortune to make another and most
important addition to our knowledge of the man-like Apes; for, being
unexpectedly detained at the Gaboon river, he saw in the house of the
Rev. Mr. Wilson, a missionary resident there, "a skull represented
by the natives to be a monkey-like animal, remarkable for its
size, ferocity, and habits." From the contour of the skull, and the
information derived from several intelligent natives, "I was induced,"
says Dr. Savage (using the term Orang in its old general sense) "to
believe that it belonged to a new species of Orang. I expressed this
opinion to Mr. Wilson, with a desire for further investigation; and, if
possible, to decide the point by the inspection of a specimen alive or
dead." The result of the combined exertions of Messrs. Savage and Wilson
was not only the obtaining of a very full account of the habits of
this new creature, but a still more important servi
