AURORA BOREALIS.—Mr. Denning writes that though the moon was nearly full on the evening of January 4 there was 3 brilliant occurrence of aurora observed from widely distant stations. The Rev. W. F. A. Ellison observed it from Fethard-on-Sea, near Water-ford, and describes it as a particularly magnificent display. From Edinburgh, at about 10 p.m., there was also a fine exhibition, extending along a considerable range of the northern horizon. Rapid variations were apparent in the details, the light alternately appearing and disappearing. Clouds were very prevalent at low altitudes in the northern region, and the glowspread upwards from behind these with striking effect. At Bristol there was an auroral glow between about 8 and 9 p.m., and at 8.30 a bright streamer shot upwards to about 15° W. of the Pole star. But the appearance was rendered somewhat inconspicuous by the unusual brilliancy of the moon, due to the very clear atmosphere.
