several important characters, the Chimpanzee is less human 
than is one or another of the Simiinse. Such characters are 
e.g, the number of the lumbar vertebrae, the shape of the 
blade-bone, of the sacrum, &c., &c. 
The Orang is most like man in (1) the development of the 
beard in the males; (2) in the development of the styloid pro- 
cess ; (3) in the length of the leg and foot taken together com- 
pared with that of the back-bone ; (4) in the length of the crest 
of the ilium ; (5) in the development of the spine of the 
ischium; (6) in the length of the foot compared with that of 
the hand ; (7) in the relative height of the cerebrum; (8) in 
the large proportion of its frontal lobe ; (9) in the small pro- 
portion of its occipital lobe ; (10) in the development of the 
“bridging convolutions;” (11) in the characters of the tongue ; 
(12) in the high and rounded form of the skull. 
The Orang, in addition to the characters before noted,* 
differs from man more than do any other of the broad-breast- 
boned Apes, in that (1) the breast-bone is formed of two 
series of pieces; (2) in the length of the leg, without the 
foot, compared with that of the back-bone ; ( 3) in the length 
of the shin-bone compared with that of the femur ; (4) in the 
length of the foot compared with that of the back-bone ; (5) in 
the length of the foot compared with that of the shin-bone ; (6) 
in the length of the foot compared with that of the spine ; (7 ) 
in the shortness of the tarsus compared with the length of the 
whole foot; (8) in the shortness of the hallux compared with 
the spine. 
Some or other of the Gfibbons are most like man in : — (1) 
the breadth of the breastbone ; (2) the shortness of the cervical 
spinous processes ; (3) the development of a “ chin ;” (4) in the 
length of the leg, without the foot, compared with that of the 
spine ; (5) the length of the blade- bone compared with that of 
the spine ; (6) the length of the haunch-bone compared with 
that of the spine ; (7) the breadth of the pelvis compared with 
the length of the haunch -bones ; (8) in the length of the 
femur compared with that of the spine ; (9) the length of 
the femur compared with that of the haunch-bone ; (10) the 
relative slenderness of the thigh-bone; (11) the length of the 
shin-bone compared with that of the femur; (12) the length 
of the foot compared with that of the leg; (13) in the length 
of the foot compared with that of the tibia ; (14) in the 
slenderness of the ankle ; (15) in the length of the great toe 
compared with that of the whole foot ; (16) the prominence of 
the nose ; (17) the form of the stomach ; (18) that of the liver ; 
(19) that of the vermiform appendix ; (20) the succession of the
