find the variation of the compass. Al-pacA. （Fabric.) a. A cloth in which the wool of the alpaca (a species of the Hama, inhabiting Peru) is combined with wool, silk, or cotton. b. A soft dress-goods, an imitation of the former; having a cotton chain and woolen filling, plain color and highly finished surface. Al′pha-bet Tel′e-graph. An apparatus which marks symbols on paper by pressure, as Morse's; or by chemical action, as Bain's; or impresses type on paper, as House's or Hughes's; in contradistinction to one whose indications are observed by the fluctuating position of a needle or needles, as Cooke and Wheatstone's, or the bell-telegraph of Bright.

keys arranged like those of a piano, and a receiving-apparatus, which included a scape-wheel, an anchor escapement, controlled by the movements of the lettered disk, and actuating a slide-valve which operated the piston of a compressed-air cylinder by which a wheel carrying type on its periphery was turned so as to present the appropriate letter indicated at the transmitting station to the paper slip which was by suitable mechanism drawn to the type-wheel to receive an impression. Professor Hughes has also invented a very ingenious printing-telegraph, depending upon the synchronous revolutions of two or more type-wheels at different stations. See printing-telegraph. Various forms of dials or pointer telegraphs have been devised by Breguet in France, Siemens and Halske and Kramer in Germany, and various improvements in the details of construction by numerous others which the limits of this article will not permit us even to refer to.

East London Water-Works, single-a the notes. The second plan was that of Branston, who punched the notes and cut the lines deeply in a plate and from this obtained a stereotype, from which he printed in the usual manner. The present plan of detached types was introduced by Hughes of London, about 1840. See pp. 310, 311, of Ringwalt's Encyclopedia of printing. Mu′sic-wire. a.

cond an eccentric draws a shaft on which the paper strip is carried forward up against the typewheel, which, by means of an interposed endless coloring band, impresses the letter then presented upon the paper. See Shaffner's Telegraph manual. Hughes's telegraph, 1856, requires but a single current for each letter; the reception and transmission of messages simultaneously over the same wire and printing from the type-wheel while in motion are provided for by appropriate devices. The mostinto two classes: those on the step-by-step principle, and those in which the type-wheel is continuously rotated by an independent motor, the circuit of the printing-hammer being closed when the letter is opposite to the printing-pad. The House, Hughes, and Phelps machines belong to the latter class, and those of Vail, Bain, and others to be cited, to the former. The most recent types of step-by-step printing-telegraphs are:— a.

with the engine, affording a more continuous record. A graduated arc and pointer are attached, to more conveniently show the pressure at the moment; and a hammer and bell or other device may also be connected to sound an alarm when the pressure exceeds a given amount. See steam-gage. Re-cord′ing-tel′e-graph. A telegraph provided with an apparatus which makes a record of the message transmitted, as the symbol telegraphs of Morse and Bain, and the type-printing telegraphs of House and Hughes, in contradistinction to the indicatortele-graph of Cooke and Wheatstone, which has a pointing needle or needles, and the audible one of Sir Charles Bright, which sounds upon bells, and the Morse as at present generally used, which is read by the sounds. See List under telegraph. Recti-fi-ca′tion. Redistillation or resublimation to free a substance from impurities or from water. Rec′ti-fier. 1. A second still for redistilling spirits, or a second chamber connected to the main
