[Being at Loch Scavig, in the Island of Skye, in a friend's yacht, in Ancnst 

 1836, the summit of the mountain which rises on the east side of the 

 harbour to the height of 2000 feet or thereabouts, was enveloped during 

 the day by a thin veil of mist, extending 3 or 400 feet below the summit, 

 and so thin as to permit the outline of the hill, as well as the rocky in- 

 equalities of the surface, to be seen through it : as night came on the 

 mist remained, but became distinctly and decidedly luminous, still continu- 

 ing so thin that the hill was seen through it : towards 8 or 9 o'clock in 

 the evening, streamers of the Aurora ascended from it for about 10 or 

 15 towards the zenith, and continued to do so for an hour or thereabouts.

 that Egypt is exempt from earthquakes (Plin. ii. 80) ; although the necessity 

 of restoring the statue of Memnon is, in some degree, evidence to the con- 

 trary (Letronne, La Statue vocale de Memnon, 1833, pp. 2526.) It is, 

 however, true that the valley of the Nile is situated outside the earthquake 

 district of Byzantium, the Archipelago, and Syria (Ideler ad Aristol. Meteor
