208 GORILLA 



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

 panzee, as will be seen in the following measures: 



Humerus. Femur. 



Man 15.0 18.5. 



Chimpanzee 10.9 11.0. 



Enge-ena 17.0 14.0. 



"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
