Part 421

2. To plate, as with gold, silver, etc., by means of electricity.

3. To restore to consciousness by galvanic action (as from a state of suspended animation); hence, to stimulate or excite to a factitious animation or activity.

4. To coat, as iron, with zinc. See Galvanized iron.

Galvanized iron, formerly, iron coated with zink by electrical deposition; now more commonly, iron coated with zink by plunging into a bath of melted zink, after its surface has been cleaned by friction with the aid of dilute acid.
