Here the falling of the lines down-to-the-left counteracts the movement in the opposite direction which is caused by the extension of contrasting edges in that direction. A crowding together of the lines, due to the diminution of intervals toward the left, adds force to the movement in that direction.

Fig. 144

In this case a movement up is caused by convergences, a movement down by crowding. The convergences are all up, the crowding down. I think that the convergences have it. I think the movement is, on the whole, up. The intervals of the crowding down diminish arithmetically.

Fig. 145

The convergences and the crowding of attractions are, here, both up-to-the-right. The Rhythm is much stronger than it was in [Fig. 144]. The intervals are those of an arithmetical progression.
