Arr. 111.—An account of some meteorological 
phenomena observed in Canada by Capt. Bou- 
nycastle, R. E.in the years 1826-7, 
At Kingston, in Upper-Canada, for many days previous 
to Tuesday, August 28th, 1827, the heavens had exhibited 
the Aurora very brilliantly, and more frequently than had 
been hitherto observed. On that night the scene was 
very grand, and [I inclose a description of it from the King- 
ston Herald. I did not witness this splendid scene, neither 
did I observe that of Saturday night, the 8th of September, 
which was nearly equal in magnificence. I saw it, however, 
now and then on other nights, and on Sunday vight, the 9th 
inst. 1 observed a most uncommon and interesting spectacle 
which did not appear to me to helong to the usual signs of the 
Aurora. That night, at aboyt dark or eight o’clock, I saw 
an arch forming in the sky which, as the obscurity of the 
night increased, became very luminous. It extended at first 
from about under Arcturus or the Lion to the Pleiades, with 
but a smal} convexity or elevation. 
Gradually and exceedingly slow it rose or became more 
convex, and at nine it attained, on its north-western limb, 
the altitude of the highest part of the body of Ursa Ma- 
jor, while it had increased in thickness very much, and being 
complete, formed a broad and highly magnificent arch of 
pale white light, which spanned a third part of the horizou.
