: SCORESBY describes the occurrence of a similar phenomenon in the Arctic Seas in July, 1813, the luminous circle being produced on the particles of fog which rested on the calm water. "The lower part of the circle descended beneath my feet to the side of the ship, and although it could not be a hundred feet from the eye, it was perfect, and the colours distinct. The centre of the coloured circle was distinguished by my own shadow, the head of which, enveloped by a halo, was most conspicuously pourtrayed. The halo or glory evidently impressed on the fog, but the figure appeared to be a shadow on the water; the different parts became obscure in proportion to their remoteness from the head, so that the lower extremities were not perceptible."—Account of the Arctic Regions, vol. i. ch. v. sec. vi. p. 394. A similar phenomenon occurs in the Khasia Hills, in the north-east of Bengal.—Asiat. Soc. Journ. Beng. vol. xiii. p. 616.
