Abstract
THE professor of electrical engineering of the Johns Hopkins University has written a compact introduction to electricity and magnetism in which stress is laid on the physical and mathematical theories. The historical order is adopted, and the first six chapters are concerned with electrostatics. A single chapter on magnetism is followed by chapters on electrodynamics and electromagnetism, and the electrical units receive special attention. The chapters on alternating currents are of value and deserve mention, as they include an elementary account of modern methods of computation. Finally, a brief description is given of the theory of conduction in gases. To condense so much into little more than two hundred pages is a noteworthy feat, and the author is to be congratulated on his presentation of the subject.
