WATSON, B.Sc., Demonstrator in Physics in the Royal College of Science, London; Assistant Examiner in Physics, Science and Art Department. LONGMANS, GREEN, & CO. LONDON, NEW YORK, AND BOMBAY. THIS book has been written to meet the changes in the general methods of science teaching, which are the outcome of the development of modern views of scientific educationalists, and which find expression in the new syllabus of the Science and Art Department. Formerly students were taught chemistry in the lectureroom, the knowledge so gained being supplemented by a minimum amount of practical work, and that almost exclusively analytical. The tendency of the present day is to make the student, from the very beginning, an investigator; to train and develop his faculties for observation; to make him find out facts and discover truths for himself; in other words, to make him think instead of merely committing to memory what others have thought. I have therefore endeavoured, as far as it is possible to do so in a text-book, to fall into line with these views. In actual practice the purely inductive method of instruction breaks down.
