45 REPORT OF NATIONAL MUSEUM, 1890. 



A few specimens of Aino hairs from the head were handed to Dr. 

 W. M. Gray, of the Army Medical Museum, Washington, who has also 

 been good enough to prepare a series of cross-sections with his usual 

 skill. From these he made some excellent photographs, which Mr. 

 Ohandlee has carefully traced in outline with the result shown in Fig. 

 70. The original photographs showed the hairs magnified 25 and 300 

 diameters, respectively, but the outlines have been reduced one-half in 

 the cut.

This conspicuous hairiness of the Ainos, in strong contrast to the 

 smooth bodies and faces of the Japanese, has led to the natural inquiry: 

 how is it possible that the Ainos should have so long occupied Japan 

 without having left some evidence of an admixture of this character 

 with the Japanese? In the first place, the Japanese are not all alike. 

 Not only do we clearly recognize two distinct types among them, dis- 

 tinguishing the upper or ruling and the lower or laboring classes, but 

 there is also a southern type in Kiushiu, with more or less hair on the 

 face, many having full beards. It is worthy of remark, in passing, that 

 these men have always been, and still are, among the ablest and most 

 influential men in Japan. Professor Chamberlain has observed that 

 the Japanese in northern Japan and in Yezo, where there would natu- 

 rally be found the greatest admixture of blood, are no more hairy than 

 those farther south. The explanation of this he finds in the fact that 

 the half-castes die out. Such families end with the third or fourth 

 generation, and the progeny show a marked tendency to baldness. The 

 children of Japanese and Aino parents are never vigorous and healthy. 



I have a photograph in my collection of a young man with a distinctly 

 Japanese physiognomy, whose body and face are as smooth and free 

 from hair as the Japanese, but whose lower limbs are black with hair.
