In July, 1973,We measured the healthy bodies of three-hundred and eighty-two children (9〜12years old) of T elementary school in Kagoshima by means of the type II silhouetter. This time we chose the best three-hundred and sixteen examples of side-silhouettes and examined their bust angle, posterior waist angle, and hip angle respectively, taking into account the distinction of the sex and age. The general results of the examination are as follows : (1) The order of the average degrees of angle of a child (from the first to the sixth grade) is (1) bust angle, " (2) posterior waist angle, (3) hip angle. But the individual variation is great in each angle. (2) The somatotype of a boy, when he reaches the age of 12,and his shoulder blades grow, making the posterior waist angle wide, comes to be like that of an adult. (3) In the case of the somatotype of a girl, the growth of her bust and hips with the onset of her adolescence is observed plainly on the side-silhouette. (4) The side-silhouette of a nine or ten-year-old child (whether a boy or a girl) shows greater individual unevenness of trunk-level than that of an eleven or twelve-year-old child.
