Since the adoption of an entrance requirement in chemistry at theM assachusetts Institute ofT echnology the problem of the instruction becomes somewhat simplified in that a certain background of chemical experience is possessed by all the students. Major experiments consisting of the preparation of inorganic substances are still believed to be the best means of training the chemical students in the laboratory, and the present edition retains the essential features of the former edition under the same title prepared by one of the authors. It has seemed very desirable to have in a single volume a comprehensive plan of laboratory work and class room study to cover a whole years work and to this end the two authors have put together the material which they formerly published separately. Experience has taught teachers that it is unwise to count too much upon an understanding of subjects previously studied. Therefore, although this book is presumed to outline a course continuing from a previous course in high school, it was thought best to include the essential material of the high school course. This elementary material was presented in the form of minor experiments for which the directions were written as if the experiments were to be performed, but the description of the observations and the discussion of the chemical principles were added. Thus by reading the text the pupil could quickly obtain a grasp of the review work. This treatment of the minor experiments however proved to be so excellent a method of imparting a knowledge of chemistry that it was followed to a large extent throughout the whole book. The preparations present the opportunity for original study; the minor experiments carry along the systematic instruction. The minor experiments can too at all times be performed when it seems desirable. This volume is therefore considerably more than a labor

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.
