SECONDARY SEXUAL CHARACTERS, 637 



for with man when the beard differs in color from the hair 

 of the head, as is commonly the case, it is, I believe, almost 

 always of a lighter tint, being often reddish. I have 

 repeatedly observed this fact in England; but two gentle- 

 men have lately written to me, saying that they form an 

 exception to the rule. One of these gentlemen accounts 

 for the fact by the wide difference in color of the hair on the 

 paternal and maternal sides of his family. Both had long 

 been aware of this peculiarity (one of them having often been 

 accused of dyeing his beard), and had been thus led to observe 

 other men, and were convinced that the exceptions were 

 very rare. Dr. Hooker attended to this little point for me 

 in Russia, and found no exception to the rule. In Calcutta 

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

 observe the many races of men to be seen there, as well 

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

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

 of which races have very little hair on the face; and he 

 always found that when there was any difference in color 

 between the hair of the head and the beard, the latter was 

 invariably lighter. Xow with monkeys, as has already 

 been stated, the beard frequently diffei*s strikingly in color 

 from the hair of the head, and in such cases it is always of 

 a lighter hue, being often pure white, sometimes yellow or 

 reddish.* 



In regard to the general hairiness 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.f 

 Lastly, male monkeys, like men, are bolder and fiercer 



* Mr. Blyth informs me that he has only seen 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 Macaeu8 cynomolgus, kept in confinement, whose mustaches 

 were " remarkably long and human-like." Altogether this old 

 monkey presented a ludicrous resemblance to one of the reigning 

 monarchs of Europe, aftr whom he was universally nick-named. 

 In certain races of man the hair on the head hardly ever becomes 

 gray; thus Mr. D. Forbes has never, as he informs me, seen an 

 instance with the Aymaras and Quchuas of South America, 



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