Excerpt from Journal of the Institution of Electrical Engineers, 1889, Vol. 18The Addresses of past-presidents of the parent Societies of Telegraph Engineers, and telegraph-engineers and Electricians illustrate also the growing desire to know something of the molecular theory or the dynamical theory of electricity and magnetism. Mr. Preece, in his Address of 1880, pointed out how Maxwell had shown the velocity of light to be related to electricity in such a way that we can scarcely doubt but that the propagation of electro-magnetic disturbance through space, which we have every reason to believe does exist - which, in fact, from known laws we may say certainly does exist - is effected with a velocity equal to that of light, and that the propagation of electrical disturbance and of light may perhaps be identical. In support of these remarks, Mr. Preece alluded to the disturbances at the sun's surface and the simultaneous magnetic disturbances which had been observed in the telegraphs and in other operations of an electro - magnetic character on the surface of the earth.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
