PREFACE TO SECOND EDITION. Since the passage of the "Free Alcohol Act" there has been a constantly increasing demand for information as to the manufacture of industrial alcohol. This, with the favorable reception accorded to the first edition of this book has lead the publishers to bring out a second edition. The entire volume has been carefully revised and not only has the original text been amplified but new chapters have been added explaining the most modern and approved methods and appliances both as used in Europe and in this country. Another valuable feature of the present volume is the collection of U. S. de-naturing formulas covering the special denaturants necessitated by the various arts and by the Government requirements. The chapters on modern distilling apparatus rectifiers and modern plants have been very carefully prepared in order to give the reader a clear idea of the various types of apparatus in use to-day and of their general place in a distillery system. The value of the book has been further increased by numerous additional illustrations. It would be impossible in the compass of one small volume to describe all the practical details of alcohol manufacture particularly as these details vary with every distillery, but it has been the aim of the author to give sufficient information to enable every reader to understand the theory and general practice of the art, leading him from the simple methods and apparatus used until the last ten years to the more complicated stills and processes which have been lately devised.
