Excerpt from Elements of Electromagnetic Theory I am of course indebted to many books and memoirs. My obligations are especially great, as the most cursory examination of the book will Show, to the works of Maxwell, Heaviside, and Poynting. I am also much indebted to Professor A. G. Webster for the use of a number of excellent diagrams from his treatise on electrical theory. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
