I will conclude with another experiment :— There is a large rock lying near the landing place of our laboratory. When the tide was at the level of the dotted line (See Fig. 6.), I placed some individuals of L. exigua which were known to be negatively phototaxic at the spot A of this rock a little below the water line. The spot was about ten feet from the high bank near the landing place. The question was whether these individuals would go in the direction of the high bank or toward the higher part of the same rock which was turned away from the general mass of land. There was no ambiguity about the answer. As soon as they were placed there, they starte! in the direction of the arrow toward the higher part of the rock A. I now took some of these negative ones to a spot on a ledge of rock.
