Figures apparently devised by Wilhelm Weber and Eduard Weber and published in their book Mechanik der menschlichen Gehwerkzeuge: eine anatomisch-physiologische Untersuchung, Göttingen: In der Dieterichschen Buchhandlung, 1836; here without the letters and numbers keyed to their text on pp. 33-34, para. 14, and pp. 39-42, para,. 18 (describing the changing positions of the left and right leg in the process of walking). The authors claim that their illustrations, made from measurements of fifteen soldiers, show that the pelvis is strongly tilted not only among women but among men, and that therefore the "best illustrations of the human skeleton are erroneous in this respect" (p. ix)
