Iloltz. is diflicnlt to fully explain without devoting more time to thegeneral subject of electrical induction than is deemed wise. It may l)eroughly summarized, however, as follows :— Any body when electrified has the power, to a greater or lessextent, of exerting (even through an intervening substance, which inthis instance consists of a plate of glass) a peculiar effect upon theelectrical state of anot
