“The electrical matter consists of particles extremely subtile, since it can permeate common matter, even the densest metals, with such ease and freedom as not to receive any perceptible resistance. If anyone should doubt whether the electrical matter passes through the substance of bodies, or only over along their surfaces, a shock from an electrified large glass jar, taken through his own body, will probably convince him. Electrical matter differs from common matter in this, that the parts of the latter mutually attract, those of the former mutually repel each other.” — Benjamin Franklin
