-
When a lighted candle is held before the eye, the pupil of which has been dilated by belladonna, three images of it are seen-two erect, and one inverted :-the former owing to reflection from the cornea and anterior surface of the crystalline; the latter owing to reflection from the posterior layer of the crystalline inverted, and between the other two. This mode of examining the eye has been proposed as a means of diagnosis between cataract and amaurosis. In the latter, all the images are seen.
