68 THE NATURAL HISTORY OF 



mbouve, which builds itself a shelter, and of another rare 

 kind with a comparatively small face, large facial angle, 

 and peculiar note, resembling " Kooloo." 



As the Orang shelters itself with a rough coverlet of 

 leaves, and the common Chimpanzee, according to that 

 eminently trustworthy observer Dr. Savage, makes a sound 

 like " Whoo-whoo," the grounds of the summary repudi- 

 ation with which M. Du Chaillu's statements on these 

 matters have been met is not obvious. 



If I have abstained from quoting M. Du Chaillu's 

 work, then, it is not because I discern any inherent im- 

 probability in his assertions respecting the man-like 

 Apes ; nor from any wish to throw suspicion on his ve- 

 racity ; but because, in my opinion, so long as his narra- 

 tive remains in its present state of unexplained and appa- 

 rently inexplicable confusion, it has no claim to original 

 authority respecting any subject whatsoever. 



It may be truth, but it is not evidence.
