Excerpt from A Text-Book of Dye Chemistry: The Chemistry of Dye-Stuffs Professor von Gborqibvics' Tsehrbuch der Farbenchemie is so well known to chemists that no further introduction is needed, and the fact that it had reached its fourth edition in 1013, under the capable editorship of Professor Grandmougin, is sufficient evidence of its popularity abroad. Although the German edition is available to English-speaking readers, the renewed interest which the war has compelled all to take in the future development of the synthetic dye industry has made it desirable that an up-to-date English translation should be prepared for those whose lack of familiarity with German may render the reading of the original a somewhat tedious business and, moreover, in carrying out the translation of the work advantage has been taken of the opportunity to bring the subject-matter up to date and to make various alterations to the original text and arrangements where it scorned desirable. Fortunately, from the reviser's point of view, the last six years have witnessed few, if any, developments of outstanding importance in the scientific and technical branches of the dye industry, though vast changes have occurred in the commercial and economic sides, which cannot, however, be discussed here. The chief additions and alterations to be noted in the present edition are: - the Tables indicating the relationships of the various derivatives of Benzene, Toluene, Naphthalene and Anthracene, the chapters on Quinoline Dyes and Coal-tar, which have been rewritten, a new section dealing with the Anthocyans, the chapter on Anthraquinone dyes and Vat colours, an account of recent work on Carminic acid and Curcumin, and, lastly, a list of all the more important books connected with the chemistry of dyes. The translation is entirely new and, wherever it has seemed desirable, references to work published during the period 1013-20 have been inserted, whilst in most cases the British Patents are referred to, as well as the German.
