The following experiments were tried : The aquarium used in previous experiments was placed before an open west window at three o'clock in the afternoon, in good dif- fused daylight. In fifteen minutes the majority of the medusae had retreated to the end of the aquarium away from the window (Fig. r> P- 356). Now a large mirror (M, Fig. 2) was placed vertically against one corner of the aquarium away from the window, so as to throw light across the end of

Now a large mirror (M, Fig. 2) was placed vertically against one corner of the aquarium away from the window, so as to throw light across the end of the aquarium. In fifteen minutes most of the medusae had collected in the opposite corner of the aquarium away from the window and where the light was least intense. The mirror was now placed at this corner and record again made in fifteen minutes. Many of the medusae were scat- tered about, but again there was a larger number collected in the.
