OEDEE OF aUADEUMANA. 595 



of tlie English, naturalist, Professor Owen. This cranium had 

 been confided to Mr. Savage by a missionary at the Gaboon, the 

 Rev. Leighton Wilson, of New York. This same missionary at 

 a later period procured a second cranium, and part of a skeleton, 

 which he presented to the Natural History Society of Boston, Mass. 



Messrs. Savage, Jeffries, Wymann, and Owen, published the first 

 scientific dissertations on the new Monkey, and to designate it, 

 they adopted the name of Gorilla, employed by Hanno. Their 

 writings have established the distinction between the species of 

 Troglodytes gorilla and Troglodytes niger, or Gorilla and Chim- 

 panzee. 



From this period, the mu.seums of London, Boston, Paris, 

 Havre, &c., have been enriched by skeletons and entire specimens 

 of the Gorilla. And as we have alreadj^ mentioned, ]\I. du Chaillu, 

 during several excursions into the forests of these regions, has 

 observed and killed a number of these animals. 



The two works in which M. du Chaillu has published these 

 observations have appeared in English and French, the first in 

 1865, the second in 1867.* From them we take the following 

 details. 



The Gorilla attains a medium height of about five feet. Its 

 muscular power is prodigious, and is equal to the strength of a 

 Lion. It is king of the forests it inhabits, and perhaps hunts 

 the Lion. The negroes never attack it except with firearms ; to 

 kill a Gorilla is an exploit which never fails to make the reputa- 

 tion of a black. 



The natural gait of the Gorilla is not that of a biped, but that 

 of a quadruped. Nevertheless it retains the vertical position 

 more easily, and for a longer time, than any other Monkey. 

 When it stands upright its knees are turned outwards, and the 

 back is bent. When it runs on its fom" feet, the length of its 

 arms causes its head to be much elevated above the rest of the 

 body. The arm and leg of the same side move at the same time, 

 so that its pace resembles a kind of oblique gaUop. When 

 pursued, the young Gorillas do not take shelter in trees, but run 

 along the ground ; their hind legs advance between their arms, 

 which are a little inclined outwards.
