The anatomy of the human body : composed (on an entire new plan,) in a method very different from all anatomical writers : designed chiefly for the use of naval practitioners, and by way of supplement to a work, entitled The marine surgeon : the whole, forming a complete repository, for the surgeons of the Royal Navy : to which is subjoined some physiological tracts, and a copious index . that perpendicular line,and the force with which it acls in any fitua-tion will be, casteris paribus, as ths lengthof that perpendicular line. The motions ofthe far greater part of the mufcles are volun-tary, or dependent on our will; thofe of afew others involuntary. Thofe mufcleswhich perform the voluntary miotions, re-ceive nerves from the brain or fpinal mar-row-, thofe which perform their motions in-voluntarily, have their nerves from the cere-bellum ; and thofe whofe motion is partlyvoluntary and partly involuntary, havetheirs in part from the brain, and in partfrom the cerebellum. And as a mufcle canno longer act when its nerve is either cutafunder, or tied up, fo nearly the fame abfo-lute dependence it has on its artery; forfrom the experiments of Steno and others,en living animals, it appears, that on cut-ting, or tying up the artery, the mufcle inthe fame manner, feme hours after, lofes itsv/hole power of aclion, as if the nerve hadbeen cut or tied up.
