ABSTRACT
The subject is of immense importance; the work described is of the highest order of experimental investigation; the results attained have contributed more than any other recent results to revolutionize the view taken by the majority of scientific workers as to the nature of electromagnetic waves. Heinrich Hertz gives in his introduction an interesting account of the steps by which Maxwell's theory may be connected with the older theories. Hertz, however, seems content to look upon Maxwell's theory as the series of Maxwell's equations. Hertz's work is, however, not concerned with any theory, but with the practical study of electromagnetic propagation along conducting wires and throughout space. Hertz is so justly famous, and on account of which Hertzian oscillators, Hertzian receivers, Hertzian waves have become in the few years since 1888 the objects of universal attention. No physical experiments have produced as great an effect on science as these experiments here described by their author.
