Third Latin edition, translated by John Leyburn. Digby's famous book on the nature of bodies and the nature of man's soul, which first appeared in English at Paris in 1644, is here printed in the third Latin edition, translated by John Leyburn (1620-1702). The first part of the work establishes the author's avid support of Harvey's doctrine in an extraordinary chapter on the motion of the heart and the actions of the nervous system.
