Abstract
A VISUAL illusion which I have never seen referred to may be of interest. If the gaze is steadily fixed for a few minutes on a spot in the descent of a waterfall which has a fairly long unbroken fall, and afterwards quickly transferred to the adjacent hillside, the hill itself appears to rise slowly as a whole, somewhat as though it were an elevator. The same result may be obtained by looking fixedly at the broken surface of a rapid and fairly wide stream; on directing the eyes suddenly to the opposite bank this appears to move slowly up-stream.
