72 RECORD OF AURORAL PHENOMENA. 



The electrometer was tried during the continuance of this evening's Aurora, but no effect was 

 perceptible either on that or a Kater's compass." — Ibid., p. 200. 



April 4, 1322. 



" The phenomenon frequently observed at Melville Island in the spring, of the white clouds assuming 

 the form of two continuous arches with their legs meeting near the east aud west horizons, was 

 finely displayed on the 4th ; the height of the arches in the centre, from the north aud south 

 horizons, being from 50° to 10°. " — Ibid., p. 20G. 



April 16, 1822. 



"Some hard, well-defined clouds, being nearly the first we had seen this season, appeared for a short 

 time to-day, and were welcomed as the harbingers of returning moisture in the atmosphere. 

 The Aurora Borealis was seen at night to the southward, and extending at times in a broad band 

 of light across the heavens, but at a low altitude, from east to west." — Ibid., p. 213. 



May 2, 1822. 



"After sunset on the evening of the 2d, a thin horizontal streak or band of vapor appeared along 

 the lower parts of the land. As the night advanced, it became thicker and more diffused, and 

 at length, for the first time this season, the ships were for an hour or two enveloped in fog." — 

 Ibid., p. 223. 



May 16, 1822. 



"On the evening of the 16th, something like small rain was falling for a few minutes, being the first 

 we had seen this season ; but it soon formed the less equivocal form of sleet, the thermometer 

 being at 31°."— Ibid., p. 228. 



June 2, 1822. 



"On the 2d, at 3h. p.m., a thin white cloud was observed to extend across the northern sky from 

 northeast to southwest, being then about 65° high in the centre. The whole of the heavens to 

 the southward of this was covered with a similar kind of cloud, that to the northward exhibiting 

 a clear blue sky. The edge, which was well defined, formed a very perfect arch, and here the 

 cloud was much more dense than in any other place, reminding one of a veil of gauze of which 

 there were more folds in that part than elsewhere. Though the wind was, with us, at W. by N., 

 it blew gently over to the S. S. E., still retaining its perfect and continuous arch-like form at 

 the margin. In a quarter of an hour, it had got 20° on the south side of the zenith, in forty 

 minutes was only 25° high, and in an hour and a quarter had totally disappeared beneath the 

 southern horizon, leaving the whole of the heavens perfectly cloudless. 

 This was the most striking phenomenon of the kind we had ever witnessed, and, while the arch 

 remained near the zenith, this magnificent canopy had a singularly grand and imposing appear- 

 ance." — Ibid., p. 238. 



Duekett's Cove.— Lat. G6° 12' 36" N. Long. 86° 44' 45" W. August 29, 1321. Tarry. 



"The morning was beautifully clear and tranquil, and the Aurora Borealis was faintly visible at 

 break of day in the southwest quarter of the heavens.'" — 1 Parry, 69. 



Chamisso Island.— Lat. 66° 13' 11" N. Long. 161° 41' 45" W. Sept. 28, 182T. Beecuey. 



" On the 24th and 28th, the nights were clear aud frosty, and the Aurora Borealis was seen forming 

 several arches. 

 On the 28th, the display was very brilliant aud interesting, as it had every appearance of being 

 between the clouds and the earth; and, after one of these displays, several meteors were observed 

 issuing from parts of the arch, ami fulling obliquely towards the earth.
