. Narrative of a journey to the shores of the Polar Sea, in the years 1819, 20, 21, and 22 [microform]. Scientific expeditions; Expéditions scientifiques. they No. III.] Da. RICHARDSON ON THE AURORA. 611 appeared pretty dense in the bright moonHght, were yet rare enough to allow the larger stars to appear through them. By one o'clock, the whole mass of cloud had gathered together towards the south, and disappeared in the horizon; but at the same time a few long and very rare threads of cloud, which were at intervals faintly luminous, shot athwart from east to west in the deep blue of the northern part of the sky. On former cccasions, the Aurora had been observed to illuminate the face of the clouds next the earth; but the present night was remarkably favourable for the observance of that phenomenon, the brightness of the moon-light, and the clearness of the sky, rendering the clouds very visible and well defined.

At midnight the sky cleared up, a few cirro-strati were seen to the south- ward, and there was a slight bur round the moon; the rest of the sky was of a grayish blue colour. At this time a broad bank of the Aurora appeared in the north, lying horizontally, at an elevation of 25°. There were also a few long parallel streamers to the westward, flashing in the direction of their lengths, from W. d. N. to E. b. S. They disappeared suddenly, leaving in their site a faint yellowish light. December 2Cth, 1820, A very dense iniHt riiin)f from the Rapid, and a fog hovering^ over the river and in the low valley.
