THIS book is intended primarily for the junior and senior engineering students of the Massachusetts Institute of Technology who are not specialising in electrical engineering. It contains an outline of lectures previously given by the author. These lectures are now discontinued, and in their place nine pages of the text are assigned each week for home study. The classroom exercises consist of three ‘recitations’ and one problem section per week. An independent laboratory course covers the same ground and follows the class exercises. The keynote of the work we are told in the preface is brevity, and since the students are nearing the end of their college studies the statements are made as rigorous as possible. Chap. xvii. is devoted exclusively to illustrations illustrating all kinds of electrical apparatus.
