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 Cyclopaedia, ' 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. In the first year of the present century a treatise was written by a Captain Jones, which has been copied, in whole or in part, into almost every work since published. The greater portion of it is absurd and impracticable, and shows that it was written by a person who undertook to teach what he had not learnt. The first work of any real utility that came under my notice was a series of papers by 'Practicus.' This was soon followed by another, varied by the new chemical nomenclature."
