much longer than the external as to give the lower part of 
the shaft an inclination outwards, as in man, the curve of the 
middle and upper portions restores its general direction nearly 
to the vertical, as in the Chimpanzée. "The femur is about 
two inches shorter than the humerus; in this respect the T. 
gorilla recedes from the human type, while he approaches it 
in the relative lengths of the ulna and humerus. 
The tibia also is considerably shorter than the human, 
and more curved both laterally and anteriorly, producing 
consequently a large interosseous space. "The upper articu- 
lating surfaces, as observed by Dr. Wyman, are on different 
planes; the internal one being the lowest and concave, the 
outer one convex ; as the lowest surface answers to the long- 
est condyle of the femur, the axes of the bones are nearly in 
the same line. The right astragalus is preserved, somewhat 
resembling the human, but flatter and longer; the articular 
surface for the tibia is less convex, and narrower posteriorly ; 
the surface for the scaphoid is more prominent, flatter, and 
with a better-marked constricted portion or neck ; the lateral 
surface for the tibia is more quadrilateral and less vertical ; 
the surface for the fibula is less triangular; the posterior por- 
tion is wider, with a less deep groove for the flexor longus 
pollicis; the surfaces for the os calcis, with the deep groove; 
are very muchas in man. There are also some carpal, meta- 
carpal, and phalangeal bones of the hand, and a few pha- 
langes of the toes ; the metacarpal bones are long and curved 
Inwards, with large lower articulating surfaces; the bones of 
ti € fingers have their edges much turned under on the ante- 
"or surface, for the protection of the vessels, nerves, and -— 
dons, as they grasp the limbs of trees in their usual idan uae 
mode of progression ; they may also serve for the insertion of 
the strong ligaments. £e gi 
Allthe bones are exceedingly solid and heavy, indicating 
Very great muscular force ; many of them bear marks of frac- 
ture and bony growths, which indicate that this was a veteran 
male, who had seen many a hard fight; the skull, the lower
