Abstract from the record:--
[14]_Dec._ 21st, 1852. Wind N.-E., fine
weather.
_Dec._ 22d. Thick, hazy morning, wind east, much lighter in S.-E. than
in N.-W.; 8 A.M., a clear arch in S.-E. getting more to south; noon,
very black in W. N.-W.; above, a broken layer of cir. cumulus, the sun
visible sometimes through the waves; wind round to S.-E., and fresher;
getting thicker all day; 10 P.M., wind south, strong; thunder,
lightning, and heavy rain all night, with strong squalls from south.
_Dec._ 23d. Wind S.-W., moderate, drizzly day; 10 P.M., wind west, and
getting clearer.
The next day the vortex passed the latitude of Montreal (the moon being
on the meridian about 10 P.M.)
MAGNETIC STORM, DECEMBER 23, 1852.
In the July number of Vol. XVI. of Silliman's Journal, we find certain
notices of the weather in 1852, by Charles Smallwood, of St. Martins,
nine miles east of Montreal. He mentions "two remarkable electrical
storms (which) occurred on the 23d and 31st of December, (in which)
sparks 5/40 of an inch were constantly passing from the conductor to the
discharger for several hours each day." At 10 P.M. (23d) the vortex
passed over Montreal, and again descending on the 31st North, and was
visible at Ottowa on the morning of the 1st of January, with southerly
wind setting towards it. On the 29th of December, Mr. Smallwood records
"a low auroral arch, sky clear." On the 20th, the vortex was 5° to the
northward of Montreal, and the aurora was consequently low--the
brightest auroras being when the vortex is immediately north without
storm, or one day to the northward, although we have seen it _very low_
when the vortex was three days to the north, and no other vortex near.
LIVERPOOL STORM.
On the night of the 24th of December, the same central vortex ascending
passed between Cape Clear and Liverpool.
On the 25th, at midnight, the vortex passed to the north of Liverpool:
its northerly progress being very slow, being confined for three days
between the parallel of Liverpool and its extreme northern limit in
latitude about 57°. The accompanying account of the weather will show
the result of a long-continued disturbance near the same latitude:
