Abstract
The Oki-islands lie about in 130 degrees of east longitude, 36 degrees north latitude. Their total area is 348.75 square kilo-metres, and total population is 20, 829 males, 22, 972 females (1948). The islands are consisted of the two grouper, Dozen and Dogo. There are many reports about the Oki-islands from the view point of archaeolgy or folklore because of many old remains and because of their distantial isolation from Honshu (mainland of Japan), but we have had few records of anthropometric researches available.
This research was made in August 1949. After the statistical treatment of the data, writer has much to say about the significant differences between the inhabitants of Dozen and Dugo in the next meanvalues.
Male: foot-length, maximum head length and cephalic index. Female: forearmlength, bitrochanteric diameter, projective height from vertex to gnation, auricular height and bigonial-breadth.
