This book does not make easy reading for the ordinary physician. It is divided into four main parts, dealing respectively with the medical implications of direct current, muscular stimulation by electricity, radiation and high frequency currents. Each of the chapters within these divisions begins with a description of what it is about, goes on to tell how such electrical methods as are mentioned should be used in treatment and ends with an outline of the results that may be expected from their proper employment. Considerable space is devoted to explaining as simply as possible the basic electrophysics and physiology of the technics involved, and in connection with this there are naturally a good many mathematical computations. At the end are two helpful appendixes which describe the use of logarithms and something of trigonometry.
A book of this character cannot be expected to have any great appeal to ordinary readers of
