Even the Serrin, about which so much has been said, is exceedingly delicate, and although it may give little trouble, if at any time it should go wrong in inexperienced hands, the result is an entire stoppage of operations, and another lamp will not in such a case be probably at hand.

He has sought to produce a steady lamp, and one that will give little trouble, that will cast no shadows, and a regulator that may be understood and worked or fed at once by any man of ordinary intelligence. Figs. 83 and 84 are views of the lamp. The same letters refer to the same parts in both figures. Fig. 83 is an end view of the lamp, and Fig. 84 a side view. A A are a pair of carbon plates, carefully made from the best materials used in the composition of rod carbons. These plates are of any suitable length, and 6 inches broad. The length may consequently be 12 inches. These plates are of different thicknesses, the positive one being the thicker because it burns away the faster. They are made to slide freely through the hollow cores of a pair of flat electro-magnets, B B, which are fastened together by a strong bridge of hard wood, C, provided with a ring for suspending the lamp.
