Dr. J. E. Gray on M. Du Chaillu's ' Adventures in Africa.' 463 



meisteri, is an interesting fact. On occasions when a pair of 

 P. Parrianiis occurred, only one individual was recorded as 

 having crepitated. When eiglit were found together, several 

 were noted as exhibiting the habit ; and two specimens, taken 

 singly, crepitated on capture.

LV. — Zoological Notes on perusing IM. Du Chaillu's ' Adventtires in 

 Equatorial Africa.' By Dr. J. E. Gray, F.R.S., V.P.Z.S. 



A SHORT time ago we were informed that there had arrived a new 

 traveller from Africa who had examined the country near the equator 

 — in fact, the tract between those examined by Livingston and Speke. 

 He read his paper before the Geographical Society ; and I suppose, 

 as I find no astronomical observations, not even any diaries of his 

 route in his 'Explorations,' and the most odd-looking ranges of 

 mountains in his maps, that they soon discovered that he had but 

 few qualifications for a scientific geographer. But some of the Fel- 

 lows of the Society seem to have been so much interested with his tales 

 of his adventures with the Gorilla and other animals, and especially 

 with his extraordinary accounts of the cannibal propensities of the 

 inhabitants, that they have assigned to him a room in their house in 

 which to show his collections, and have invited the fashionable world 

 of London to come and inspect them. 



If these gentlemen had been as conversant with zoology, and 

 especially with the zoology of Western Africa, as they are with its 

 geography, they would soon have discovered that IVI. du ChailUi 

 was as little able to extend the domains of zoological aud ethno- 

 logical science as he was to be a good geographer ; but vuifortunately 

 some persons are often most interested in that which they know least 

 about.
