SEXUAL selection: man. 
Part II. 
In regard to the general hairyness of the body, the- 
women in all races are less hairy than the men, and in 
some few Quadrnmana the under side of the body of 
the female is less hairy than that of the male.^^ Lastly, 
male monkeys, like men, are bolder and fiercer than 
the females. They lead the troop, and when there is 
danger, come to the front. We thus see how close is 
the parallelism between the sexual differences of man 
and the Quadrumana. With some few species, how- 
ever, as with certain baboons, the gorilla and orang, 
there is a considerably greater difference between the 
sexes, in the size of the canine teeth, in the develop- 
ment and colour of the hair, and especially in the 
colour of the naked parts of the skin, than in the case 
of mankind. 
The secondary sexual characters of man are all highly 
variable, even within the limits of the same race or 
sub-species ; and they differ much in the several races. 
These two rules generally hold good throughout the 
animal kingdom. In the excellent observations made 
on board the Novara , the male Australians were found 
to exceed the females by only 65 millim. in height,, 
whilst with the Javanese the average excess was 218 
millim., so that in this latter race the difference in height 
and confined Macacus cynomolgus, whose moustaches were “remarkably 
long and human-like.’’ Altogether this old monkey presented a ludicrous 
resemblance to one of the reigning monarclis of Europe, after whom he 
was universally nick-named. In certain races of man the hair on the 
head hardly ever becomes grey; thus Mr. D. Forbes has never seen, 
as he informs me, an instance with the Aymaras and Quichuas of 
S. America. 
This is the case with the females of several species of Hylobates, 
see Geoffrey St.-Hilaire and F. Cuvier, ‘ Hist. Nat. des Mamin.’ tom. i. 
See, also, on II. lar. ‘ Penny Encyclopedia,’ vol. ii. p. 149, 150. 
“ The results were deduced by Dr. Weisbach from the measure- 
ments made by Drs. K. Scherzer and Schwarz, see ‘ Eeise der Novara t 
Anthropolog. Theil/ 1867, s. 216, 231, 234, 236, 239, 269.
