(the largest cavities of the brain) ventricle, Its existence in the 
apes, to the exclusion of all other animals except man (for this, 
so far as known, is a fact), is the more remarkable, inasmuch 
as the posterior lobes of the brain, which contain the cornua, are 
very inconsiderably developed in them. 
_In the circle of their functions, and in the phenomena of pe- 
riodicity, the apes, again, make a close approach to the human 
pecies 
The dissections which have been made of the gorilla’s carcass, 
show an identity almost, in character and relations of the soft 
parts, with those of the other species of the Troglodytes. 
The skin of the gorilla, in the young as well as in the adult, is 
of jet black color, and is very thick and firm. The skin of the 
female, is generally darker than that of the male. Black, with few 
exceptions, appears to be the skin-color of apes, though some do 
not obtain it till after the period of adolescence. The face of 
the chimpanzee, when young, is yellow, while that of the young 
nshiego-mbouvé, is astonishingly white. The skin of each is 
clothed all over with hair, which also is black or gray. The 
hair of a fully grown, but not aged gorilla, is said to be of iron- 
gray color—the black hair is intermixed with gray, and so 
Tinged, as to produce this particular shade. The longest and 
darkest hair—sometimes over two inches long—is on the ante- 
nor extremity ; from the shoulder to the elbow, it grows down- 
rds; on the forearm, upwards. The back of the hand is 
hairy to the division of the fingers, which have a more —

but his larger size, and more compact organization, deprive 
him of their agility of motion—and so, by good right, of their 
the sloth, a bungled composition of nature.” é 
The gorilla is se poked Ag ave originated in Africa—at any 
rate he makes his abode in the equatorial belt, of that continent. 
According to DuChaillu, his range of migration 1s between 
8° north, and 8° south latitude, and as far into the interior, 
as Captain Barton’s Lake Tanganyika. Over this region of
