 note = {It has been investigated the activity variations of the three fundamental types of atmospherics which were analysed in the preceding Part 1. of this paper. In the early stage of the development of a cumulo-nimbus the partial discharge type is  predominant over the other two. If the cloud becomes more active，the wave forms of the leader type present themselves more frequently than that of the partial discharge type. On the occasion of a thunderstorm， the two types other than the main discharge type are simultaneously observable as well as the latter type, provided the thundercloud is large and active.},
