The physical characters of the Ainu and the Japanese differ profoundly. The Ainu present a peculiar and strongly marked type. On the whole they are short; Batchelor gives 5 ft. 4 in. as the average stature for men and 5 ft. 1½ in. or 5 ft. 2 in. as the average for women. It is true, however, that stature varies considerably with locality—the men of Shiraoi being relatively tall and well built, those of Piratori medium, and those of Ishikari smaller and badly developed. The Ainu skin, though dark, is white, not yellow or brown; the color appears darker than it really is because the Ainu rarely bathe. The hair is abundant both on the body and the head, and is wavy; the color is commonly black, though it may be dark-brown or even reddish; like wavy hair everywhere, it presents an elliptical, not a circular, cross-section. The beard in males is strong and abundant. The features are those of the white race rather than the yellow; the nose is prominent and well formed, the mouth is strong; the lips firm. The eyes are brown, sometimes even light brown. Mark these characters well; compare them with those of the Japanese. How profound the difference. The white skin, abundant body hair and beard, the hair wavy and of elliptical section, the horizontal eye full of expression and fire, the features combined into a strong relief—these are in strong contrast to the yellow-brown skin, hairless face and body, straight and round hair, oblique eyes and flat face of the Japanese. In all these respects in which the Ainu differs so profoundly from the Japanese, he resembles us, the whites of European race. They are often called “the hairy Ainu” and we consider the term just. It is true that their proximity to the smooth-bodied yellow Asiatics has made their hairiness conspicuous by contrast. It is true that many writers, who have spoken of “fur” and “missing links,” have overstated facts; but it is also true that notably hairy bodies are the rule among the males. Individual Russians are no doubt common, who are as hairy as the average Ainu, but we believe firmly that taken _en masse_ the Ainu are more hairy than the Russians, and probably the hairiest people on the globe. Of course, the Ghiliaks, living on the Asiatic mainland and undoubtedly related with them, present the same peculiarity. Hitchcock gives a lot of excellent data in regard to Ainu hairiness.
