Abstract
THE article by Dr. C. F. C. Beeson in Nature of October 26, p. 572, is a welcome attempt to sort out the many conflicting references to a subject of much importance and of wide interest. Numerous factors go to the growth of a plant, and I felt many years ago that it was necessary first to find out the chemical and physical effects of moonlight under simple controlled conditions. The research was carried out chiefly under the bright moonlight of South Africa. Moonlight is partially polarized, the maximum effect being with the oblique reflexion of half-moon, or somewhat later for the waxing and earlier for the waning moon.
