During his stay in Java from 1944 to 1945, the author made an anthro-pometric survey of the aboriginal inhabitants of Djawa and Madoera Islands. It covered 12, 825 males and 1, 682 females from six ethnic groups, the Djawanese, the Soendanese, the Madoerese, the Batavians, the Tenggers and the Badoejs. The statistical study of the data leads to the following conclusions.
(1) Stature. It differs among different ethnic groups and socio-economic classes. The Djawanese are taller than the Soendanese and the Madoerese. The difference may be due to geographical factors more than racial ones. Personnels of government offices, students, and soldiers of the volunteer army forces are tall with bodies adequately built, while inhabitants of moun-taineous regions and manual labourers are short with slight bodies possibly due to chronic malnutrition and other unbalanced living conditions. The average hight of the manual labourers is 3.5cm smaller than that of the public officials and the soldiers.
(2) Sitting Vertex Hight. In general it is very short (83-85cm). There is not any significant difference in the dimension between the ethnic groups with the exception only of the Badoejs who are extremely short.
(3) Leg Length. It was obtained by subtracting the sitting hight from the stature. Legs are longest among the students and shortest among the manual labourers. Of the six ethnic groups the Badoejs have the longest legs. Among the Badoejs the extremities are markedly long while the trunk is short.
(4) Span of Arms. The average span of arms of the Badoejs is much greater than that of all the other ethnic groups, while there is very little difference in the dimension between the latter groups (Index of span of arms 105-106).
(5) Transverse Dimensions. The dimensions are greater among the mountain inhabitants and the soldiers than those among farmers of flat countries and coulies of cities.
(6) Body Weight. It is greatly influenced by food and nutritional circum-stances. The manual labourers are unusually light in body weight.
(7) The aborigines of the islands, like the Indians and the Arabs, are characterized by a short trunk and relatively long extremities. These characters in body proportion seem related to the climatic factors in the tropics.
