 note = {Using the night time waveforms observed in June 1955 the author analysed mainly the ionospheric reflection type waveforms having two series of peaks, and derived that the two reflecting layers were considered to be parallel in E layer at ahout 5 km apart. The waveforms of such type were observed every night during the period of observation and have more or less directional characteristics. In these waveforms the distance from origin can be rather easily determined than in the usual reflection type waveforms because of having two series of peaks. But it is to be noted that peaks of any series can not be reflected from both layers irregularly but from only one layer respectively. But in this paper amplitudes of the reflected peaks could not be investigated as well as the theoretical treatment of the existence of two layers.},
