A propos du livre

Présentation de l'éditeur

In the eighteen years which have elapsed since the pubhcation of the first edition, not onl have great advances been made in the chemical knowledge on Mhich the manufacture is based, but new points of view have been gained, involving an acquaintance with physical and colloidal chemistry which is not yet uni ersal 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, hovever, 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 Mamijacture, 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 MrF. 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. A tkin for his permission to insert the paper on hydrion measurement which appears in

Présentation de l'éditeur

This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.
