Book excerpt: Excerpt from The Principles of Leather Manufacture In the eighteen years which have elapsed since the publication of the first edition, not only have great advances been made in the chemical knowledge on which the manufacture is based, but new points of view have been gained, involving an acquaintance with physical and colloidal chemistry which is not yet universal among leather-trade chemists, and I have felt compelled to enter into elementary details of these branches of science which, no doubt, in a few years will be among the commonplaces of chemical knowledge. I must therefore repeat the apology of the first preface, that to some of my readers much will necessarily seem too elementary, while to others it may prove too difficult, though I have endeavoured, as much as possible, to confine mathematical treatment to notes and appendices. It may be pointed out, however, that the advance of the future will necessarily tend to exact and mathematical methods, and that many theories which seem plausible enough when stated qualitatively and in general terms will break down when submitted to the rigorous examination of mathematics. The third volume on the Methods of Leather Manufacture, which was suggested in the former preface, yet remains to be written, but advancing age renders such a work impossible to the present writer, and its execution must be left to some of the young and well-trained chemists who are now devoting themselves to the trade. It is my pleasant duty to acknowledge much indebtedness to Mr F. C. Thompson, my Assistant in the Procter International Research Laboratory, not only for re-writing the chapters on the Chemistry of Hide and on that of the Tannins, with which he has made himself specially familiar, but for much general assistance both in the preparation of the work and in the reading of proofs; to Mr W. R. Atkin for his permission to insert the paper on hydrion measurement which appears in Appendix D, and also for help in proof-reading; and to the various gentlemen who have given information and allowed me to use their blocks and drawings in illustration; and especially to Mr A. Seymour-Jones, Professor McCandlish, Mr J. T. Wood, and Mr M. C. Lamb. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
