Abstract
ACCORDING to the theory of the Röntgen rays suggested by Sir G. Stokes,1 and recently developed by Prof J. J. Thomson,2 their origin is to be sought in impacts of the charged atoms constituting the kathodestream, whereby pulses of disturbance are generated in the ether. This theory has certainly much to recommend it; but I cannot see that it carries with it some of the consequences which have been deduced as to the distinction between Röntgen rays and ordinary luminous and non-luminous radiation. The conclusion of the authors above mentioned,3 “that the Röntgen rays are not waves of very short wave-length, but impulses,” surprises me. From the fact of their being highly condensed impulses, I should conclude on the contrary that they are waves of short wave-length. If short waves are inadmissible, longer waves are still more inadmissible. What then becomes of Fourier's theorem and its assertion that any disturbance may be analysed into regular waves?
