The Author, in this fifth edition, has endeavoured to give an account of the principal discoveries which have been made within the last four years in Chemical Science, and of the various important applications, such as the gas-lights, and the miner’s-lamp, to which they have given rise. But in regard to doctrines or principles, the work has undergone no material alteration.
