Abstract

Objects of the last experiment are one hundred thirty-one women students (whose ages are from nineteen to twenty) of our Jr.College. By using the silhoetter machine we measured their form of drooping arms necessary to structure of sleeves. The results were as in the following : 1) On the length of arms Their length of arms (which is from shoulder points to ulnar styloid process points) averaged 52.27cm (±2.32), and their length of elbows (which is from shoulder points to olecranon points) averaged 28.95cm (±1.64). In the former and the latter was found a remarkable individual variation. 2) On the slant form of arms As regards the angles of inclination in ulnar styloid process points, the average was 5°25'(±2.79) in the front. The front slant form was found in ninety-seven percent of students, and the angles have a very wide distribution. As regards the angles of inclination in olecranon points, the average was 0°13'(±2.82) in the front. As regards the angles of elbow, the average was 168°31'(±4.51). 3) A high plus correlation was found in the relation of angles between ulnar styloid process points and olecranon points (Y=-3.4+0.69X), and in the relation of angles between olecranon points and elbow (Y=168.3+0.65X).
