express any motion; because it cannot move, if some of its muscles do not relax while the others are pulling. Those which relax cease to appear in proportion as the others pull strongly and become apparent.
Chap. LVI.—Of the Muscles.
The muscles of the human body are to be more or less marked according to their degree of action. Those only which act are to be shewn, and the more forcibly they act, the stronger they should be pronounced. Those that do not act at all must remain soft and flat.
Chap. LVII.—Of the Bending of the Body.
The bodies of men diminish as much on the side which bends, as they increase on the opposite side. That diminution may at last become double, in proportion to the extension on the other side. But of this I shall make a separate treatise[1].
Chap. LVIII.—The same Subject.
The body which bends, lengthens as much on one side as it shortens on the other; but the central line between them will never lessen or increase.
- ↑ It is believed that this treatise, like many others promised by the author, was never written; and to save the necessity of frequently repeating this fact, the reader is here informed, once for all, that in the life of the author prefixed to this edition, will be found an account of the works promised or projected by him, and how far his intentions have been carried into effect.
