Abstract
THE question of the size, charges and velocities of the carriers in the kathode rays has been made the subject of investigation by Prof. J. J. Thomson, Lenard, and others. I do not know whether it has been noticed that, by taking the values which have been obtained for the ratio of charge to mass, and for the velocity of the particles, in connection with the observed fact that a shaft of rays from a plane kathode retains its cylindrical form unaltered as it passes across the tube, we can arrive at a limiting value for the mass per unit volume of the matter composing the rays.
