摘要：Many techniques of recording of bodily movements reported, up to date, offered diffrent technical and economic advantages in their use, but their difficalties offen prevented the advancements of this field. The analysis of bodily movements by Tracergram is reported in this paper. The beams of the lamps fixed on the fingertips, ankles and waists are taken on the same photographic plates. The two female students, well trained and untrained, are subjected to our experiment. This device makes possible precise study of exactly what motions are effecient, and give valuavle clues as to how unskilled motions may be suggested to correct.
