Part 663

{ E*lec`tro-punc`tu*ra"tion (?), E*lec`tro- punc`tur*ing (?; 135) }, n. (Med.) See Electropuncture.

E*lec`tro-punc`ture (?; 135), n. (Med.) An operation that consists in inserting needless in the part affected, and connecting them with the poles of a galvanic apparatus.

E*lec"tro*scope (?), n. [Electro- + -scope: cf. F. électroscope.] (Physics) An instrument for detecting the presence of electricity, or changes in the electric state of bodies, or the species of electricity present, as by means of pith balls, and the like.

Condensing electroscope (Physics), a form of electroscope in which an increase of sensibility is obtained by the use of a condenser.

E*lec`tro*scop"ic (?), a. Relating to, or made by means of, the electroscope.

E*lec`tro*stat"ic (?), a. Pertaining to electrostatics.

E*lec`tro*stat"ics (?), n. (Physics) That branch of science which treats of statical electricity or electric force in a state of rest.

E*lec`tro-ste"re*o*type (?), n. Same as Electrotype.

E*lec`tro-tel`e*graph"ic (?), a. Pertaining to the electric telegraph, or by means of it.

E*lec`tro-te*leg"ra*phy (?), n. The art or science of constructing or using the electric telegraph; the transmission of messages by means of the electric telegraph.

E*lec`tro-ther`a*peu"tics (?), n. (Med.) The branch of medical science which treats of the applications agent.

E*lec`tro-ther"man*cy (?), n. 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.

E*lec"tro-tint` (?), n. (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.

E*lec`tro*ton"ic (?), a. 1. (Physics) Of or pertaining to electrical tension; -- said of a supposed peculiar condition of a conducting circuit during its exposure to the action of another conducting circuit traversed by a uniform electric current when both circuits remain stationary. Faraday.

2. (Physiol.) Relating to electrotonus; as, the electrotonic condition of a nerve.

E`lec*trot"o*nize (?), v. t. (Physiol.) To cause or produce electrotonus.

E`lec*trot"o*nous (?), a. Electrotonic.

||E`lec*trot"o*nus (?), n. [NL., fr. combining form electro- + Gr. &?; tension.] (Physiol.) The modified condition of a nerve, when a constant current of electricity passes through any part of it. See Anelectrotonus, and Catelectrotonus.

E*lec"tro*type (?), n. [Electro- + -type.] A facsimile plate made by electrotypy for use in printing; also, an impression or print from such plate. Also used adjectively.

The face of an electrotype consists of a shell of copper, silver, or the like, produced by the action of an electrical current upon a plate of metal and a wax mold suspended in an acid bath and connected with opposite poles of the battery. It is backed up with a solid filling of type metal.

E*lec"tro*type, v. t. [imp. & p. p. Electrotyped (?); p. pr. & vb. n. Electrotyping (?).] To make facsimile plates of by the electrotype process; as, to electrotype a page of type, a book, etc. See Electrotype, n.

E*lec"tro*ty`per (?), n. One who electrotypes.

E*lec`tro*typ"ic (?), a. Pertaining to, or effected by means of, electrotypy.

E*lec"tro*ty`ping (?), n. The act or the process of making electrotypes.

E*lec"tro*ty`py (?), n. The process of producing electrotype plates. See Note under Electrotype, n.

E*lec`tro-vi"tal (?), a. Derived from, or dependent upon, vital processes; -- said of certain electric currents supposed by some physiologists to circulate in the nerves of animals.

E*lec`tro-vi"tal*ism (?), n. (Physiol.) The theory that the functions of living organisms are dependent upon electricity or a kindred force.

E*lec"trum (?), n. [L., fr. Gr. &?;. See Electric, and cf. Electre, Electron.] 1. Amber.
