VI. On the motion of the lorentz electron

Motion of the Lorentz JE'lectrom49 given out in quanta, which represent the differences between the energies in two steady s~ates of motion.When, however, the numerica.1 value of the appropriate constants in the formula of Ritz is considered, it is found that the magnetic forces set up by the atom are not in themselves sufficient to account for more than a small fraction of the effect that would be necessary to give the observed distribution of lines in spectral series.University of London, King's College.
