We have here a remarkable instance of the power of light in retarding and hastening the revolving movement.(See ERRATA.)Convolvulus sepium (large-flowered cultivated var.) moves against the sun.Two circles, were made each in 1 hr.42 m.: difference in semicircle from and to the light 14 m.

Plumbago rosea (Plumbaginaceae) follows the sun.The shoot did not begin to revolve until nearly a yard in height; it then made a fine circle in 10 hrs.45 m.During the next few days it continued to move, but irregularly.On August 15th the shoot followed, during a period of 10 hrs.40 m., a long and deeply zigzag course and then made a broad ellipse.The figure apparently represented three ellipses, each of which averaged 3 hrs.38 m.for its completion.
