32 THE NATURAL HISTOEY OF 



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 veri- 

 table existence, of course a strong resumption 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 an- 

 other 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. Yv T ilson, with a desire for further investiga-
