I THE CHIMPANZEE 29

 Asiatic islands of Borneo and Sumatra. 



And while the progress of discovery thus cleared 

 up the history of the Orang, it also became

 the eastern world were the various species of 

 Gibbon Apes of smaller stature, and therefore 

 attracting less attention than the Orangs, though

 and are hence more accessible to observation. 



Although the geographical area inhabited by 

 the " Pongo " and " Engeco " of Battell is so much 

 nearer to Europe than that in which the Orang 

 and Gibbon are found, our acquaintance with the 

 African Apes has been of slower growth ; indeed, 

 it is only within the last few years that the truth- 

 ful story of the old English adventurer has been 

 rendered fully intelligible. It was not until 1835 

 that the skeleton of the adult Chimpanzee became 

 known, by the publication of Professor Owen's 

 above-mentioned very excellent memoir " On the 

 Osteology of the Chimpanzee and Orang," in the 

 Zoological Transactions a memoir which, by the

By the investigations herein detailed, it became
