Abstract
DISTORTION OF SUN'S DISC AT HORIZON.—Prof. W. Prinz, of the Royal Observatory of Belgium (Brussels), has obtained several large-scale photographs of the setting sun, which show most distinctly the considerable deformation of the disc when near the horizon. The instrument employed was a photo-heliograph by Steinheil. A reproduction of one of the photographs accompanies the note in Mem. della Soc. degli Spettroscopisti Italiani, vol. xxxi. pp. 36–39. In this case the ratio of the vertical diameter to the horizontal one is as 75:84 = 0.893.
