[Footnote 13: a c sia. In the original text b is written instead of c—an evident slip of the pen.] Let a b c be the fold of the drapery spoken of above, a c will be the places where this folded drapery is held fast. I maintain that the part of the drapery which is farthest from the plaited ends will revert most to its natural form.
Therefore, b being farthest from a and c in the fold a b c it will be wider there than anywhere else.

Windsor Pl. XXX for farther illustration of what is here stated.]
