Chap. LXXXIV.—Objection to the above answered, Plate XI. and XII.
It has been objected, in regard to the first part of the above proposition, that it does not follow that a man standing still, or moving slowly, has his members always in perfect balance upon the centre of gravity; because we do not find that Nature always follows that rule, but, on the contrary, the figure will sometimes bend sideways, standing upon one foot; sometimes it will rest part of its weight upon that leg which is bent at the knee, as is seen in the figures B C. But I shall reply thus, that what is not performed by the shoulders in the figure C, is done by the hip, as is demonstrated in another place.
