ME. ST. GEOEGE MIYAET ON THE SKELETON OE THE PEIMATES. 
The same, compared with that of the spine, is only exceeded by Tarsius, unless it 
may be sometimes also by Simia. 
Compared with that of the manus, it is less than in any except Hylobates. 
Compared with the tibia, it is longer than in any except Simia. 
The cuboid bone is longer, in proportion to the os calcis, than in any except Man, 
Hylobates, Nyctipithecus, Hapale, Lemur, and the Nycticebinse. 
The proportion of the hallux, with its metatarsal, to the spine is greater than in 
any other except Tarsius, and sometimes Hylobates. 
The proportions of the longest digit, and of the metatarsal of the hallux to the 
spine, are greater ; the first than in any genus of the order except Tarsius and Simia, 
and perhaps Ateles ; the second than in any except Tarsius and Hylobates. 
The proportion of the hallux to the pollex is less than in any others except Hylo- 
bates, Hapale, Simia, and Tarsius. 
The length of the longest digit of the pes, compared with that of the manus, is less 
than in any except Hylobates and the Chimpanzee. 
The third digit, without its metatarsal, when compared in length with the pes, I have 
only found exceeded by Loris*. 
Cheiromys differs from absolutely every other Primate in — 
1. The great length of the manus as compared with that of the rest of the pectoral 
limb. 
2. The great breadth of the two ends of the humerus compared with the length of 
the bone. 
3. The manus being more than once and a half the length of the radius. 
4. The great predominance, in length, of the third metacarpal over the others. 
5. The great excess, in length, of the first phalanx of the third digit over its meta- 
carpal. 
6. The length of the pollex as compared with that of the longest digit. 
7. The slenderness of the third as compared with the other digits of the manus. 
8. The length of the longest digit, without its metacarpal, compared with that of the 
longest metacarpal. 
Thus Man is but one of several exceptional forms of the Primates ; nor does it appear 
that the bony structure of his limbs presents more peculiarities of form and proportion 
than may be detected in that of Tarsius, if even so many. 
Again, the differences in anatomical structure between the appendicular skeleton of 
Man and that of certain Apes is certainly less than that which exists between the same 
parts in other genera which are counted by followers of Cuvier as Quadrumana, and 
therefore cannot have an ordinal value. 
As might have been anticipated, it is the os innominatum and foot which supply 
the great majority of the absolutely distinctive characters. But the pelvis of Man 
differs decidedly less from that of the Gorilla than does the latter from that of Loris ; 
-* I have not been able to compare Brachyurus, Callithrix, Nycticebus, and Perodicticus.
