320 SEXUAL selection: man. PartIL 



In regard to the general liairyness of the body, the 

 women in all races are less hairy than the men, and in 

 some few Quadrumana 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. Tliey lead the troop, and when there is 

 dano-er, 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 heiglit, 

 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." Altogrether this old monkey presented a ludicrous 

 resemblance to om; of the reigning monarchs 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. 



10 This is the case with the females of several species of Hylobates.

11 The results were deduced by Dr. Weisbach from the measure- 

 ments made by Drs. K, Scherzer and Schwarz, see ' Keise der Novara : 

 Anthropolog. Theil,' 1867, s. 216, 231, 234, 236, 239, 269.
