within a few feet, say eight or ten, of the earth.* It was the most 
splendid sight | ever beheld. When the sheet, in its progress westward 
passed over a mill-pond, it was greatly agitated, spread around con- 
se with an infinite number of auroral sparks, like electricity, 
though of the auroral color, illuminating quite a section of the atmo- 
fer I supposed at the time, it was the effect of the exhalations 
from the pond, which was not frozen over. ier it seemed to strike 
the western hill it condensed, and appeared so much like fog Mrs. C. 
said it was fog, but upon being reminded it was too early in the evening 
for fog, and also pointing her to stars which could be seen through it, 
she relinquished the idea.t We-now came to the woods through which 
I drove ee nearly one mile and an half, and when we came out it 
filled th € Roninere at the north with the red light which was seen 
every where. 
2. Aurora Borealis of February 19,1852; by Prof. D. Kirxwoop, 
(from a letter to the editors, dated Del laware Tollege. )—Incomparably 
the grandest auroral display | have ever seen has been observed here 
this evening. My attention was first called to the phenomena about 
20 minutes before 10 o’clock. An unusually heavy auroral cloud ex- 
tended across the northern horizon, the dark segment rising in the cen- 
ter to an elevation of about 20%. Streamers of extraordinary brilliancy 
ited. frequently almost to the zenith, and sometimes even beyond it. 
es, or rather waves of lambent light, having an almost flame-like 
appearance, incessantly succeeded each other in all the northern hem- 
isphere, from the horizon towards the zenith. t 10h. 5m. a column 
of light from 3° to 4° broad, and having a reddish tinge, shot up from 
the northwest, passed precisely over Mars, and kept its position about 
half a minute. If this was elsewhere observed it might enable us to 
determine the elevation of the meteor. Perhaps it may be worthy of 
remark that a greenish tinge was observed in mers luminous spots 
which broke out from time to time in the auroral clot 
As | write this hasty note the aurora is gradually Gadieg. The un- 
dulations, however, are still distinctly. visible, 
Friday morning.—| have just been informed that the streamers had 
not disappeared at 3 o’clock this morning.
