Edwards, in 1846, introduced a lamp, Fig. 1161, in which two carbon electrodesare enclosed in small cases, meeting obliquely on a refractory and badly conducting substance. Thepoints are brought into place, as consumed, by springs. A sliding-piece and screw beneath the baseboard enable the length of the voltaic arc to be regulated.

ELECTRICAL ENGINEEEING. 567 Staite and Petrie, as well as Foucault, in 1848, devised a method by which the current regulatedthe distancing of the carbons. This was based upon the phenomena that an electric current cancause magnetization according to its strength; that the voltaic arc as part of the conductor, reactsupon the current. This lamp, however, was never introduced into practical use ; in principle it wassimilar to Archereaus lamp. Fig. 1162 is of Archereaus lamp, tlie basis of many ideas, and one of the most simple andeffective of its kind. It consists of a hollow coil of copper wire, with a vertical standard, two carbon
