One of those agents passing through the earth and all substances, without giving any outward signs of its presence, when at rest; yet when active, often producing violent and destructive effects. It is supposed to be a highly elastic fluid, capable of moving through matter. Clouds owe their form and existence, probably, to it; and it passes through all substances, but more easily through metals, water, the human body, &c., which are called conductors, than through air, glass, and silk, which are called non-conductors. When bodies are not surrounded with non-conductors, the electricity escapes quickly into the earth.
To what part of bodies is Electricity confined?
To their surfaces, as the outside may be electric, and the inside in a state of neutrality. The heat produced by an electric shock is very powerful, but is only accompanied by light when the fluid is obstructed in its passage. The production and condensation of vapor is a great source of the atmospheric electricity.
Condensation, the act of making any body dense or compact; that is, of bringing its parts into closer union.
In what other sense is the term Electricity employed?
This term is also employed to designate that important branch of knowledge which relates to the properties shown by certain bodies when rubbed against, or otherwise brought in contact with, each other, to attract substances, and emit sparks of fire.
Designate, to point out by some particular token.
Emit, to send forth, to throw out.
