Not illustrated. 1904 Excerpt: ...that an explanation should be sought in the hypothesis that Rontgen rays were single pulses travelling through the aether. Ordinary light is to be represented as a series of regular waves, succeeding each other at periodic intervals, many thousand waves, almost exactly similar to each other, following in order in a minute fraction of a second. According to this view, Rontgen rays must be regarded as single disturbances, propagated with the same velocity as light, but not followed by a train of waves. The thickness of the pulse, in which the whole disturbance is concentrated, is considerably smaller than the wave-length of any visible light. On Maxwell's theory, now universally accepted, light is explained as a series of electro-magnetic waves; and we must therefore imagine the Rontgen pulses to be electro-magnetic also. But, as we have said, Rontgen rays are produced when a cathode ray strikes a solid object; and, if we take the cathode rays to be streams of electrified particles, it may be shown that electro-magnetic pulses will be started by their impact. Let us examine the electric properties of these moving particles by means of the conception of tubes of force, a conception which we owe to the instinctive insight of Faraday. A small electrified body, carrying, let us suppose, a negative charge, is well known to attract other bodies in the neighbourhood when those bodies are positively electrified, and to repel them if their charges be negative. Rejecting the idea of action at a distance, Faraday regarded these electric forces as transmitted by stresses and strains in the dielectric or insulating medium, and represented the state of that medium by a series of lines, drawn everywhere so as to lie in the direction of the force on a positively electrified ...
