The book in the reader's hand is a translation of the second edition of the Comte du Moncel's "L' Eclairage Electrique" published at Paris, by the Messrs. Hachette, in 1880. While the general reader will find in the following pages all that he can possibly require to know about electric lighting, it is believed that the book may prove of more extended and important utility, by supplying serviceable guidance to the daily increasing number of persons who are called upon to consider how far this latest gift of science can be applied to their purposes.
