MAN AND APES.

He is most nearly approached in this respect by the Spider 
Monkeys (^Ateles)^ while in the Gribhons it is even longer than 
in man. 
Comparing the length of the thigh-bone with that of the 
haunch-bone, we find the short-tailed Indris to he the most 
human, while Hylohates is more so than are the higher genera 
of Simiince. 
In man the relative length of the thigh-bone to the humerus 
is enormously greater than in any latisternal ape. The Lemurs 
approach us most nearly in this proportion, while, as regards 
the slenderness of the thigh-bone, the Gribhons agree with us 
much more than do the thick thigh-boned Orang, Chimpanzee, 
and Grorilla. 
The “ neck ” of the thigh-bone is especially long and well 
defined in man and in the latisternal apes, but the Grorilla in 
this respect is the least human of the latter. 
The lower end of the thigh-bone of man is distinguished by 
the much greater projection downwards of its inner part (inner 
condyle). It is not, however, the Simiince,, but the Spider 
Monkeys, and some Baboons, which in this character present 
the nearest resemblance to ourselves. 
The length of the shin-bone, compared with that of the back- 
bone, is greater in man than in any of the Old World apes, ex- 
cept the Gribhons, in which its relative length is even a little 
greater than in man. Some of the Spider Monkeys resemble 
him in this, more than do any other Primates. 
The length of the shin-bone compared with that of the thigh 
bone is much the same in the Grorilla and Chimpanzee as in man. 
In the Gribhons it is rather longer, relatively, and in the Orang 
considerably longer. In the Slow Lemur, however, the propor- 
tion is almost as human as in the Grorilla. 
When the length of the entire foot is compared with that of 
the back-bone, the Orang appears at much disadvantage (as to 
resemblance to man) in comparison with all the other latisternal 
apes ; the baboons, however, excel the last-named animals in 
this respect. 
When the length of the foot is compared with that of the 
entire leg without it, the Gribhons are seen to take precedence 
(as to human likeness) not only of all the other latisternal apes, 
but of all other Primates whatever, except the Nycticebince, 
If the length of the foot be compared with that of the shin- 
bone, the Gribhons come absolutely to the front rank of the 
whole order, while the Orang is seen to be, in this respect, the 
most inhuman of all Primates. The proportion as to length 
borne by the foot to the hand is more human in the short- 
tailed Indris than in any other Primate ; while, of the latisternal
