A-eri-al car. A car adapted for traveling in the air. The name is somewhat loosely applied, and may mean one of three things: — 1. The basket or receptacle of a balloon. 2. A car whose weight is partially or entirely counterbalanced by a balloon, and which travels on wires by means of driven wheels. See next article. 3. A car on an elevated railway. A-e′ri-al Rail′way. An attempt to govern the balloon or aerostat by guiding rails or wires stretched between posts. Fontaine's aerial Railway. Fontaine's Aerial Railway, February 5, 1867, may be taken as a sample. The weight of the car is counterbalanced by an attached balloon. The cigar-shaped car is driven by steam, the deeply indented side-wheels travelling upon wires which rest upon brackets whose flanges project into the circumferential depressions in the wheels. The wire-way supported on posts has been adopted for carrying freight. See wire-way. Ae-ro-hydro-dy-nam′ic wheel. A mode of tra

When cold, the plate is reduced to an even thickness by a planing-machine. For printing, it is mounted on a wooden backing. Another mode of obtaining electrotype plates from a letter-press form is by a mold of gutta-percha, brushed with graphite and immersed in the electroplating bath. Gutta-percha is also used for obtaining intaglio molds and then cameo impressions from woodcuts, for printing. See electro-plating. E-lec′tro—typo-graph′ic ma-chine′. An apparatus invented by Fontaine, a French barrister, for printing short legal documents, etc. The letters of the alphabet—caps, lower-case, figures, etc.—are arranged around two horizontal disks, one above the other, and surmounted by a third disk which has notches corresponding to the types below. A bar in the center is caused to press upon the notch representing any particular letter, which is, by electro-magnetic action, caused to drop and leave its impression on a sheet of paper wound upon a roller beneath, a

nt degree, the metal is run off. The consumption is said to be 15 to 18 bushels of pitcoal, 2 bushels of charcoal, making a ton of refined from 22 cwt. of pig metal. The fluid iron from the blast-furnace is sometimes transferred direct to the refinery, thus saving the time and fuel required for remelting the pig-metal. Various fluxes have been patented or proposed for assisting the process. Hampton, 1856, slakes quicklime with a solution of alkali or alkaline salt. Du Motay and Fontaine use scoriae from the pudding-furnace, oxides of iron and alkaline silicates or carbonates; Sanderson, 1855, uses substances containing oxygen or other element, by which silicium, aluminium, etc., are removed. Blackwell proposed remelting in a cupola furnace alone, or with the addition of substances containing nearly pure iron oxides. Nasmyth and others have employed steam passed through or caused to impinge upon the molten metal in a state of ebullition. Bessemer, in 1855, patented a
