Abstract
THE German edition of this standard work of reference has already been reviewed in these columns (vol. xlvi. p. 313). The translator and editor has done good service in rendering the work more available to English technologists by adding a preliminary section on the raw materials used in the industry, as well as by giving prominence in the tables to English patents. In these particulars the present edition differs from the German, and its value from the English point of view is thereby greatly enhanced. The work is also brought up to date, as all the later discoveries are tabulated. The total number of colouring matters now recorded is 454, as against 392 in the last German edition (1891). Even while Mr. Green was preparing the translation new products were being introduced, and no less than twenty-two new compounds have had to be added in an appendix. Another valuable addition to the English edition is the synoptical table for the qualitative analysis of artificial colouring matters, which was published by the translator last year in the Journal of the Society of Chemical Industry, and which is reprinted at the end of the volume.
