The Pelvic Limb. 
The entire length of the pelvic limb, measured from the summit of the femur to the 
distal end of the longest digit, is absolutely greatest in Man, and then in the Gorilla, 
Orang, and Chimpanzee successively. 
The absolute length of the leg, without the pes, is again longest in Man and the 
Gorilla ; but in the Chimpanzee it is longer than in the Orang. 
The entire length of the pelvic limb, compared with that of the spine, is greatest by 
far in Tarsius, the former being nearly twice and a half as long as the latter. Then 
follow Hylobates and A teles, in which I find the pelvic limb to be more than once and 
three fifths the length of the spine. Man and Galago follow, the proportion being in 
them a little less than one and a half to one. Cheiromys and some of the Cebidse 
and Hapale succeed, and in all, the limb is at least one-tenth longer than the spine, 
except in Lemur, Perodicticus, and Arctocebus. It is less than the spine in Lemur, 
and still less in Perodicticus, while in Arctocebus it is least of all — about 85 - 2 to 100. 
The proportion borne by the limb, without the pes, to the spine is greatest in Tarsius, 
being more than once and a half the length of the latter, then Hylobates, once and 
a quarter, or a little more. In Man the proportion is as about 117 to 100. The limb 
is a trifle longer than the spine in Ateles, and scarcely shorter than it in Galago, 
Lagothrix, and Indris ; in all the others it is above seven-tenths its length, except in 
Perodicticus and Arctocebus, in which it is as 65 to 100. 
The proportion borne by the entire pelvic limb to the entire pectoral one is far 
greatest in Galago, where the first is considerably more than once and a half the length 
of the second. In Indris it is as about 144 - 5 to 100, in Man and Nyctipithecus as about 
135. In the rest it is less, but still the pelvic limb is longer than the pectoral one, 
except in Ateles* and the Simiinse, in which it is shorterf, being sometimes only as 
75-2 to 100. 
The length of the pelvic limb minus the pes, compared with that of the pectoral one 
without the manus, is greatest in Galago and Indris, the first being in each more than 
once and a half the length of the second. Man follows (145 to 100), then Calli- 
thrix and Nyctipithecus . (about 137 to 100), and all the other forms have the pelvic 
limb the longer, except in the Chimpanzee, Ateles, the Gorilla, Hylobates, and Simia, 
the proportion in the last being only as about 73'4 to 100. 
Os INNOMINATUM. 
Throughout the order this bone consists of parts and processes homologous with 
those existing in Man ; yet in him it assumes a form and proportions strikingly different 
from those existing in any other Primate. 
* Professor Huxley notices the greater length of the pectoral limb in Ateles. See * Medical Times,’ 1864, 
vol. ii. p. 93. 
t According to Dr. Lucae (loc. cit. p. 280) the proportion decreases in the following order: — Man, the 
Chimpanzee, Hylobates, the Gorilla, the Orang.
