The following paper is the continuation of the account of experiments on the moving striations in neon tubes already communicated. In the previous experiments the discharge was excited by an induction coil, but in these direct current was used and the magnitude of the current was under control. Three Geissler tubes (A, B, C) were used, diameters of the capillary arts were respectively 2⋅2 mm., 1⋅41 mm. and 1⋅27 mm., their lengths being 10⋅8 cm., 7 cm. and 8⋅5 cm. These tubes (A and B) had auxiliary platinum wire electrodes at the ends of the capillary parts of the tubes to measure the drop of potential along that part.
