The strength of the right hand was measured by the strain gauge dynamometer, the knob of which, placed at different positions, was pushed upwasds with the right hand by three female subjects in standing posture. The nearer the knob to the body, the greater the strength of the hand. It was greatest especially when the knob was placed at the point 10 cm in the front of the right shoulder. Such a horizontal distribution in the expression of the hand strength was the more markedly observed, the heigher or lower was the knob placed.
