In biology, galvanism is the contraction of a muscle that is stimulated by an electric current. In physics and chemistry, it is the induction of electrical current from a chemical reaction, typically between two chemicals with differing electronegativities. (wikipedia)

GAL'VANISM, n. from Galvani of Bologna, the discover.

Electrical phenomena in which the electricity is developed without the aid of friction, and in which a chemical action takes place between certain bodies.

Galvanism is heat, light, electricity and magnetism, united in combination or in simultaneous action; sometimes one and sometimes another of them predominating, and thus producing more or less all the effects of each: usual means of excitement, contact of dissimilar bodies, especially of metals and fluids. [Webster's 1828 Dictionary]
