negative electricity

GNU Webster's 1913

1. adj. (Elec.) the kind of electricity which is developed upon resin or ebonite when rubbed, or which appears at that pole of a voltaic battery which is connected with the plate most attacked by the exciting liquid; -- formerly called resinous electricity. Opposed to positive electricity. Formerly, according to Franklin's theory of a single electric fluid, negative electricity was supposed to be electricity in a degree below saturation, or the natural amount for a given body. See Electricity.
