3.—An animal in which the erect position had become a 
settled mature character. The body generally with- 
out hair; but some on the head and forehead, and 
perhaps a little on the back. 
These steps are only an expansion of Man’s ontogeny; and 
I have shewn in discussing the changes in hairiness the reasons 
for supposing these steps. The further development of the last 
stage would seem to lead directly to the Bosjesman; and from 
such a stock it would be possible for the various races of Man to 
have branched off somewhat in this fashion. 
1.—Races with woolly hair, slight beards, and monkey- 
like faces with broad noses. They are, perhaps, a 
derivation from and improvement of the Bosjesman. 
2.—Races in which the hair became almost lost ; and these 
seem to have further developed and split up into— 
(a) Races which acquired by reversion, hair on the 
head, but little or no beard. 
(b) Races similarly advanced, but in which the nose 
has considerably developed and has become 
very prominently elongate, or as I might say, 
of the catarhine type. 
8.—Aryan race, which also acquired head-hair by rever- 
sion; and still later obtained much hair on the face. 
The nose tends to become elongate in adult age. 
4.—Native Australians, which in the matter of hairiness 
seem to be still further advanced than the Aryans. 
“Their faces so heavily bearded that scarcely the 
nose is perceptible among the mass of hair which 
covers the cheeks nearly up to their eyes. Several 
of the elder men are very remarkable for the de- 
velopment of the hair, which covers the whole of 
the breast and arms with a thick coating of pile.” * 
As I have remarked this hairiness of the breast is exactly the 
last acquired feature in Europeans, and by earlier inheritance 
it will become more pronounced in time, provided, of course, 
that vitality is sufficient to maintain it.
