154 Disturbance of the Earth’s Magnetism. 
from the western limb of the arch were slightly tinged with redness ; 
all the others were white. At Lowville, flashes of light are deseri- 
bed as arising from the north to the zenith, and thence descending 
half-way to the southern horizon. It was brilliant at Auburn, Duteh- 
ess, Erasmus Hall, Lansingburgh, Hartwick, Lewiston, North-Sa- 
lem, Plattsburgh, Rochester, St. Lawrence, Union, and Utica. An 
aurora also appeared on the 12th of the same month, and a bril- 
liant one was likewise seen in the State of New-York, at Auburn, 
Dutchess, Franklin, Fredonia, Ithaca, Lansingburgh, Lewiston, Mid- 
dlebury, North-Salem, Plattsburgh, Pompey, St. Lawrence, Utiza. 
Faint auroras are also mentioned as appearing in England on the 
13th and 14th, and another on the evening of the 25th; but no 
corresponding ones are described in the Regents’ Report. 
In 1831, the first aurora described in the Annals, is that of the 
7th of January,; ‘and of all the aurore boreales,” says the author, 
‘“‘that have been observed here (in England) the last twenty years, 
(some say forty,) this was the most extensive the most beautiful in 
colors, and the most interesting on account of the singular pheno- 
mena which it displayed, in the number of distinct luminous bows 
which were presented in the course of the night.” Several com- 
munications are given on the subject of this aurora, in the Annals of 
Philosophy, andthe Journal of the Royal Institution. It was seen 
at Paris, and at Brussels. A particular description is given of its 
appearance in Utrecht, by Prof. Moll. On inspecting the Reports 
for 1831, I find that an aurora was seen in the State of New-York, 
at places in the extreme east and west part of the State—at North- 
Salem on the east side of the Hudson river, and Fredonia near 
Lake Erie ; and intermediate to these places, at Utica, and Pom- 
pey- The Annals also mention that faint auroras were seen on the 
evening preceding and following, and also an aurora on the 11th. 
An aurora was noticed at several places in New-York on the eve- 
ning of the 6th, but none on that of the Sth or 11th. 
No auroras are mentioned in the Annals under the meteorology 
for February, but three are noticed for March ; the first, an interest- 
ing one, appeared on the 7th; the second on the 8th; and the ~ 
third, a bright one, on the 11th. By referring to the Reports of 
the Regents, it will be seen that auroras were observed on the 
same evening in several places in the State of New-York. 
The next aurora mentioned in the Annals, is that of the 19th of 
April, which has been the principal subject of this paper. An inter-
