[Letters to Editor]

Abstract

ALTHOUGH there can be little doubt that the explanation of the long streaks of light seen on examining a bright point through a half-closed eye, which is given in NATURE, vol. xiv. p. 350, is the right one, and may be proved to be so in other ways than those noted, yet I think the Fig. 5, which is supposed to represent the course of the rays of light, ought not to remain uncorrected. It will be seen in that figure that the eye, and particularly the front convex surface of the crystalline lens, makes the rays diverge, instead, of course, of making those that catch the watery prism converge a little less.
