moved off with considerable velocity to the east and 
west. At 9 o’clock, when the moon rose, the arch 
had entirely disappeared, and the horizon, in that 
direction, wore an uncommonly dark appearance, 
except where illuminated by the pale colored pil- 
lars, which still continued to shoot up towards the 
zenith, fringed, as before, with red clouds. Borders 
of transparent red clouds were then gathered in the 
north-east and north-west, the former of which was 
particularly red and luminous, and remained sta- 
tionary for some hours, giving out light, flying 
clouds of the same color, which soon disappeared. 
As the night advanced, the light continued to grow 
dimmer and more confused in form and color, until 
the whole disappeared entirely. 
The weather, for some time previously, had been 
uncommonly pleasant for the season, except a slight 
snow on the morning of the 24th. On the day 
succeeding the aurora, the weather was fine. The 
thermometer stood at 22 degrees at sunrise, and 34 
at sunset. The barometer at 29.54 inches at sun- 
rise, and 29.10 at sunset. No rain fell until the 
7th of F ebruary, except a slight shower on the 30th. 
The weather remained fair and unusually pleasant 
and warm, with brisk winds from the S. and S. E. 
On the 3d of F ebruary, hazel bushes were in bloom, 
and doves and frogs were heard singing ; the ther- 
mometer for some days ranging from 30 to 60 
degrees.
