Paris: Fortin, Masson, 1842. Wraps. First Edition. 257-384 pp. 8vo. Brown paper wraps with chipping at edges but remarkably clean and intact given the age. Interior clean with many sheets uncut. Encased in custom cloth and leather pamphlet case. Very Good.
First published account in original wraps of Carlo Matteucci's (1811-1868) experiment in which he discovers that each heartbeat of a frog is accompanied by an electrical signal. This discovery eventually forms the basis for electrocardiography (EKG). Figures 1 & 2 of dissected frog legs on folding plate at rear help to illustrate the theory.
