1. adj. See Magnetism and Mesmerism.
2. n. Same as hypnotism, at one time believe to be due to a force more or less analogous to magnetism, which, it was alleged, is produced in animal tissues, and passes from one body to another with or without actual contact. The existence of such a force, and its potentiality for the cure of disease, were asserted by Mesmer in 1775. His theories and methods were afterwards called mesmerism, a name which has been popularly applied to theories and claims not put forward by Mesmer himself. See Mesmerism, Biology, Od, Hypnotism.
