    PREFACE. During the last ten years the manufacture of Aniline and its coloured derivatives has grown from nothing to propor- tions never dreamed of by their discoverers. The hitherto unattainable brilliancy of these colours dazzled the public, and their popularity increased with astonishing rapidity. Simultaneously with the progress of Aniline industry, curiosity was naturally awakened as to the manufacturing details by which such bright colours could be obtained from coal. The several steps of the Aniline manufacture have fre- quently been set forth, and the theories by which chemists account for the production of Aniline and the colours derived from it have been explained on several occasions. But none of these accounts, though many of them are trustworthy, give a clear representation of the actual state of the manu- facture as adopted on a commercial scale. Nowhere do we find a plain statement of the methods of obtaining aniline and its derivatives, nor a description of the apparatus actually in use in manufactories. The Author of the following treatise has made it his object to supply this want. He has endeavoured to give a compre- hensive and accurate account of this industry as it is carried
