304 SEXUAL SELECTION: MAN. [Part II 



ilar difference between the two sexes in the Australians. 

 With monkeys, when there is any difference in the voice, 

 that of the male is more powerful. We have seen that 

 certain male monkeys have a well-developed beard, which 

 is quite deficient, or much less developed, in the female. 

 No instance is known of the beard, whiskers, or mustache 

 being larger in a female than in the male monkey. Even 

 in the color of the beard there is a curious parallelism 

 between man and the Quadrumana, for when in man the 

 beard differs in color from the hair of the head, as is often 

 the case, it is, I believe, invariably of a lighter tint, being 

 often reddish. I have observed this fact in England, and 

 Dr. Hooker, who attended to this little point for me in 

 Russia, found no exception to the rule. In Calcutta, Mr 

 J. Scott, of the Botanic Gardens, was so kind as to ob- 

 serve with care the many races of men to be seen there, as 

 well as in some other parts of India, namely, two races in 

 Sikhim, the Bhoteas, Hindoos, Burmese, and Chinese. 

 Although most of these races have'very little hair on the 

 face, yet he always found that when there was any differ- 

 ence in color between the hair of the head and the beard, 

 the latter was invariably of a lighter tint. Now with 

 monkeys, as has already been stated, the beard frequently 

 differs in a striking manner in color from the hair of the 

 head, and in such cases it is invariably of a lighter hue, 

 being often pure white, sometimes yellow or reddish. 9

9 Mr. Blyth informs me that he has never seen more than one instance 

 of the beard, whiskers, etc., in a monkey becoming white with old age, 

 as is so commonly the case with us. This, however, occurred in an aged 

 and confined Macacus cynomolgus, whose mustaches were "remarkably 

 long and human-like." Altogether this old monkey presented a ludicrous 

 resemblance to one of the reigning monarchs of Europe, after whom he 

 was universally nicknamed. In certain races of man the hair on the 

 head hardly ever becomes gray ; thus Mr. D. Forbes has never seen, as
