Supplement to Spons dictionary of engineering, civil, mechanical, military, and naval. r at its other end makes contact with the connection of asecond candle, when released by the consumption of the first. The objections to the Jablochkoif candle on the score of difiiculty in relighting, and loss of currentconsumed in the fusion of the insulating material, lead De Meritens to place between the two carbonrods, but not in contact with them, a third rod, of about half the diameter, instead of the insulatingsubstance. The electric arc plays from the outer carbons to the intermediate rod, which is con- ELECTEICAL ENGINEEEING. 577 sumed. The arc thus divided has less probability of total extinction, and requiies lower expendi-ture of power to produce, as it has less distance to leap. Eapieffs candle lamp, Fig. 1180, is a return to mechanical aid. There is no insulating materialbetween the carbon rods, and their distance apart is regulated by a screw. The holder of one of thecarbons is connected to the armature of an electro-magnet concealed in the stand. When no current 1180.
