RECORD OF AURORAL PHENOMENA. 87 



December 16, 1830. 



"There was little to note this clay but a splendid Aurora." — Ibid., p. 494. 



January, 1831. 



"The Auroras were very inconspicuous; but the halos were of a very striking character." — Ibid., 

 p. 503. 



February, 1831. 



" 7th and 8th. There was nothing remarkable but a slight Aurora." — Ibid., p. 504. 



March, 1831. 



" 1st. There was a bright Aurora. 

 2d. There was a bright Aurora." — Ibid., p. 506. 



"As the expedition which I commanded in 1818 did not winter in the arctic regions, my observa- 

 tions during that voyage were confined to the months of September and October, daring which 

 time the ships were moving in a southerly direction from the latitude of 74° to 58° N. ; when 

 it was observed that from the latitude of 74° until 66° the phenomenon was seen to the southward, 

 particularly at midnight; but that when the ship had passed to the southward of the latitude of 

 66°, it was seen to the northward. In several instances, the Aurora was distinctly observed to be 

 between the two ships, and also between the ships and the icebergs; proving unquestionably 

 that it could not be at that time beyond the atmosphere of the earth. This, indeed, was the 

 only fact which I completely established during that voyage." — 2 Ross, Appendix, pp.- 113-14. 



Victoria Harbor (Gulf of Boothia).— Lat. 70° 09' N. Long. 91° 34' W. Jan. 8, 1832. Ross. 



"The thermometer came down to 45°, but, being calm, it was not very cold. It is certain, also, 

 that we had now resumed our winter standard of sensation on this subject. The Aurora was 

 again seen on Saturday (the 8th)." — 2 Ross, p. 624. 



On the Ice.— Lat. 70° 20' N. Long. 174° 13' E. March 21, 1823. Von Wrangell. 



"I availed myself of the unavoidable delay to take a meridian altitude, which gave our latitude 70° 

 20'; the longitude, deduced by angles from points visible on the mainland, was 174° 13', the 

 variation 21^ E. 

 We profited by the light of a beautiful Aurora in the northeast quarter to continue our march 

 until the night was far advanced, when we had accomplished twenty-four wersts since noon, 

 among old hummocks and loose snow, which afforded comparatively easy travelling." — Von 

 Wrangell, p. 332. 



"The winter of 1822-23 was generally considered a very mild one at Nijnei Kolymsk. The tem- 

 perature was only once as low as — 51° (on the 10th of January), and Auroras were rare, and 

 not so brilliant as usual." — Ibid., p. 318. 



X. B. — Winter mild. Auroras rare ; not brilliant.

Middle Ice of Baffin's Bay— Lat. 71° 20' N. Long. 62° 28' W. Sept. 21, 1852. Inglesfield. 

 " A calm, lovely night, with brilliant Aurora and starlit sky, gave symptoms of fine weather, which,
