'Engeko,' or "Enche-eko," by which Battell knew it.

In seeking for a specific name for the "Enge-ena," however, Dr. Savage
wisely avoided the much misused 'Pongo'; but finding in the ancient
Periplus of Hanno the word "Gorilla" applied to certain hairy savage
people, discovered by the Carthaginian voyager in an island on the
African coast, he attached the specific name "Gorilla" to his new ape,
whence arises its present well-known appellation. But Dr. Savage, more
cautious than some of his successors, by no means identifies his ape
with Hanno's "wild men." He merely says that the latter were "probably
one of the species of the Orang;" and I quite agree with M. Brulle, that
there is no ground for identifying the modern 'Gorilla' with that of
the Carthaginian admiral.

Since the memoir of Savage and Wyman was published, the skeleton of the
Gorilla has been investigated by Professor Owen and by the late
Professor Duvernoy, of the Jardin des Plantes, the latter having
further supplied a valuable account of the muscular system and of many
of the other soft parts; while African missionaries and travellers have
confirmed and expanded the account originally given of the habits of
this great man-like Ape, which has had the singular fortune of being
the first to be made known to the general world and the last to be
scientifically investigated.

Two centuries and a half have passed away since Battell told his stories
about the 'greater' and the 'lesser monsters' to Purchas, and it has
taken nearly that time to arrive at the clear result that there are
four distinct kinds of Anthropoids--in Eastern Asia, the Gibbons and the
Orangs; in Western Africa, the Chimpanzees and the Gorilla.
