沙流アイヌの舌の運動能について(<特集>沙流アイヌの共同調査報告)(金田一京介博士古稀記念)

抄録

The test of the abilities of rolling of tongue edges and vertical rounding of one tongue edge shows a significant difference between the Ainu anb the Chinese in the former ability, between the Ainu and the local Japanese, between the Ainu and the mixed Ainu-Japanese in the latter ability. The percentage of inability of the Ainu to roll the tongue is much lower than that of the American, the Chinese, and the Japanese so far as the data hitherto recorded concern. The study of the mode of heredity of tongue rounding is in progress.
