THE CHIMPANZEE 2t

descended again to the ground to eat it, whereas the
chimpanzee would occasionally take a banana and
climb into the bush to eat it. Both of these animals,
however, and also the native, climb in much the
same manner. They hold on to the sides of the
tree with the hands, place the bottom of the foot
obliquely on the side next to them, and walk up it,
meanwhile depending in a great degree on the big
toe. This toe, however, is very much larger in the
chimpanzee than in man ; itis, indeed, like the thumb,
one of the most variable characters of this group of
animals, and in the marmosets is nearly wanting
altogether.

The chimpanzee squats on his heels, the gorilla
sits down like a man, and sticks his legs out in front
of him. The male chimpanzee is five feet high at
the most, and the female is nearly as big, whereas the
male gorilla, who may exceed six feet in height, is
always much larger than the female. But the great
difference is in the faces, that of the gorilla having
the powerful brow-ridges which make him look so
brutish and ferocious, which ridges, like the crest on
the top of the skull, are almost absent in the females
and their young, and only grow into prominence as
the males approach maturity. The chimpanzees
have their eyebrows much less marked in both sexes,
and are altogether of more graceful build and
pleasanter appearance.
