SINCE the amount of knowledge that is supposed to constitute an elementary scientific education increases every year, there is sufficient justification for the publication of a series of science manuals designed to meet the growing requirements of the Science and Art Department examinations, and this work is an excellent representation of such a series. Apart, however, from the value of this book as an examination manual, it possesses considerable merit. The matter contained in it is just about as much as would cover the course usually taken in a year's school work; the explanatory text is couched in the clearest language, and the experiments described are capable of being easily brought to a successful termination. Also the 235 illustrations will be of considerable assistance to the student, whilst the many exercises and examination questions interspersed throughout the book may be useful tests of his knowledge. The text-books that in their day have been eminently successful, if unrevised, must be supplanted by others which take a more extended view of the subject; hence it is that this book will compare most favourably with any written for the purpose of imparting a rudimentary knowledge of magnetic and electrical phenomena and the laws by which they are governed.
Magnetism and Electricity.
