Excerpt from Technical Methods of Chemical Analysis, Vol. 1: Edited by George Lunge in Collaboration With E. Adam, English Translation From the Latest German Adapted to English Conditions of Manufacture Since the publication of Volume I., the preparation of a new German edition has been undertaken by Professor Lunge and Dr E. Berl, of which the two first volumes were published in 1910, and the third volume in 1911. The sections comprised in this second volume of the English edition are included in the second and third volumes of the new German edition, which is being issued in four volumes. Advance proofs of these sections have been placed at the disposal of the Editor, so that the subject matter has been brought thoroughly up to date; this has been effected by including, in association with the additions made by the respective revisers of the English translation, all such additions as are applicable to English conditions of work that have been made in the new German edition. The section on Organic Dyes, from Volume IV. Of the German edition, has been included in this volume, as it forms a suitable sequel to the section on Coal Tar.
