much further from the human proportions than they do in the Chim-

“Thus in one the femur is three inches longer than the humerus. 
In the Chimpanzee these bones are nearly of the same length; and in 
the enge-ena the humerus is three inches longer than the femur, 
indicating on the part of the enge-ena a less perfect adaptation to 
locomotion in the erect position than in the Chimpanzee.” 
Whether the conclusion last reached by the distinguished com- 
parative anatomist judging from these bones is altogether correct, or 
not, reports of those, who have seen the gorilla in its haunts, appear to 
establish the fact that this Ape walks more frequently upon its legs 
only, than does the Chimpanzee, but the position assumed can only 
be called erect when compared to going upon all-fours, for even Du 
Chaillu, who leans towards the opinion expressed by Prof. Owen 
states that “when standing up the knees are bent at the joints outward, 
and his back has a stoop forward” not a very erect attitude, and his 
walk is a ‘waddle’ and he “balances himself with his arms.” On the 
other hand I have seen a Chimpanzee walk as erect and without effort, 
alone and unsupported as any man. In a certain degree, no doubt, this 
was the result of instruction and practice, but it proved that this Ape 
could walk erect with ease, and it is exceedingly doubtful, considering 
the Gorilla’s huge bulk, the enormous protruding paunch, the short 
comparatively feeble legs, and the almost entire lack of neck to permit 
the head to be thrown back, that walking erect would ever be other 
than a difficult feat, and one requiring much effort. It might stand 
comparatively erect, when it rises to make an attack, but its general 
‘build’ is more favorable to going on all-fours, its usual mode of 
progression, than to the erect method. The Gorilla has thirteen pairs 
of ribs; man but twelve, but excepting the skull, the skeleton is more | 
nearly like that of man than of any anthropoid ape. The skull of the 
Gorilla with the very limited capacity for the brain, and this last having 
the cerebrum not extending beyond the cerebellum, indicates a very 
low order of intelligence, and degrades the animal to the ferocious 
beast that he is. In the young the skull has a more rounded braincase, 
but as its possessor grows older the form changes; the braincase
