The following pages are intended to exhibit a summary view of the new art of procuring light, by means of carburetted hydrogen gas obtained from pit-coal, and which of late has been employed with unparalelled success, as a substitute for candles and lamps, and is known by the name of Gas-Light.
To accomplish this object, I have given, in the first part of this Essay, a concise and popular view of the chemical theory and production of artificial light—I have explained the action of candles and lamps—I have shown the methods of measuring the comparative illuminating power of artificial light of different kinds, so as to appreciate their economical value—I have stated the proportions of combustible materials requisite for producing a light of a certain strength; with such other preliminary facts and observations as were deemed necessary to enable the reader to understand fully the nature of the new art of illumination, which it is the object of this Essay to describe.
