This book presents in an exceptionally clear and direct manner the subject matter of a concise yet sufficiently comprehensive course for those beginning the study of physics whether in the college, the technical institute, or the secondary school. The principles are made clear by application to household affairs and other every-day experiences. Although adapted to the requirements of beginners, those who have previously studied physics will also welcome the concise review of principles and the many applications and illustrations. In addition to its merits as a textbook, it constitutes a most interesting and useful manual on household appliances and processes. Any one who is interested either in knowing just how the familiar appliances work, or in equipping a house according to the most modern methods, will find in Professor Lynde's book a wealth of stimulating and highly practical information.
