[PREFACE.]

Until within the last few years there was scarcely any work in English, that I am aware of, on the subject of Pyrotechny, worth reading, with the exception of an Article in "Brewster's Cyclopædia," by MacCulloch; and this, besides being accessible to only a few, having been published in 1830, made no mention of colours, which form the most beautiful part of the art.
