Electro-thermancy noun That branch of electrical science which treats of the effect of an electric current upon the temperature of a conductor, or a part of a circuit composed of two different metals.
Electro-tint noun (Fine Arts) A style of engraving in relief by means of voltaic electricity. A picture is drawn on a metallic plate with some material which resists the fluids of a battery; so that, in electro- typing, the parts not covered by the varnish, etc., receive a deposition of metal, and produce the required copy in intaglio. A cast of this is then the plate for printing.
Electro-vital adjective Derived from, or dependent upon, vital processes; -- said of certain electric currents supposed by some physiologists to circulate in the nerves of animals.
Electro-vitalism noun (Physiol.) The theory that the functions of living organisms are dependent upon electricity or a kindred force.

. See under Balance .
Electrometry noun [ Confer French électrométrie .] (Physics) The art or process of making electrical measurements.
Electromotor noun [ Confer French électromoteur .]
1. (Physics) A mover or exciter of electricity; as apparatus for generating a current of electricity. 2. (Mech.) An apparatus or machine for producing motion and mechanical effects by the action of electricity; an electro-magnetic engine.

[ New Latin , from Greek .... See Electric
.] (Physics & Chem.) One of those particles, having about one thousandth the mass of a hydrogen atom, which are projected from the cathode of a vacuum tube as the cathode rays and from radioactive substances as the beta rays; -- called also corpuscle . The electron carries (or is) a natural unit of negative electricity, equal to 3.4 x 10 -10 electrostatic units. It has been detected only when in rapid motion; its mass, which is electromagnetic, is practically constant at the lesser speeds, but increases as the velocity approaches that of light. Electrons are all of one kind, so far as known, and probably are the ultimate constituents of all atoms. An atom from which an electron has been detached has a positive charge and is called a coelectron .
