Preliminary experiments on the anodic oscillation in glow discharge having no positive column are carried on, and they yield the following results. (1) Whenever the oscillation exists a faint small glow ball appears at a small part of the anode. When only one glow ball appears, one series of wave consists of the only kind of wave-form. On the contrary, in case of two balls two distinct wave-forms appear, and they are smoothly connected when the ratio of the period of each wave-form is integer. (2) It is easy to make the glow ball appear, when the anode has very small surface area compared with that of the cathode. (3) The oscillating zone is located only in the glow ball. (4) The degree of modulation of light intensity variation of the glow ball is 100%. The light intensity pulse builds up at the point where the current is minimum, and it reaches to peak preceding the maximum of the current wave. When two glow balls exist they alternately flush, and one of them corresponds to one of current wave and the other to another one. The results are discussed in comparison with a hypothesis hitherto accepted, and they lead to a conclusion in which the conventional theory seems to be not always applicable to quantitative treatment of the oscillatory phenomena.
