Abstract
THE new number of Pflüger's Archiv. (III. i.) contains a paper by Prof. L. Hermann “On the absence of currents in uninjured inactive muscle.” Munk's views are criticised and a new experiment described, in which the gastrocnemius of a frog is prepared for investigation, in such a way that no contact between the cutaneous secretion and the surface of the muscle (a source of currents in previous observations) takes place. With a galvanometer of 1,600 windings, giving a deviation of 300 sc. for an ordinary nerve current, the muscle so prepared gave only a deviation of 10 to 20 sc. “We are hereby justified,” says the author, “in supposing that with a still more careful method of preparation, by the avoidance of yet other unknown causes of injury, we shall at last get a muscle perfectly free from currents.”
