Electricity, as well as Galvanism, produces muscular contractions in animals, a short time after death.
Facts in which Galvanism and Electricity differ from each other.
Some good conductors of electricity are not good conductors of Galvanism; as was shewn by Dr. Fowler.
The manner of exciting Galvanism is different from that of exciting electricity;—the former being collected most copiously from conductors, and the latter from non-conductors.
The electric fluid affects the sense of smelling—but no smell has ever been observed from Galvanism.
The electric shock operates on the body by a sudden and percussive effect—while the one which follows the Galvanic process seems to arise from a constant current, attended by a jarring and tremulous sensation.
In the decomposition of water by Galvanism, hydrogen gas is formed at one of the wires, and oxygen at the other. In that by electricity, both gases arise from the same wire.
