are thus noticed, with the Regents’ Reports, the following results 
are obtained : 
The first aurora mentioned in the Annals for 1830, occurred on 
the 19th of April. A particular description is given of its appear- 
ance in England, and also a notice of its being seen in Scotland. 
In the State of New-York, a brilliant aurora was extensively seen 
on the same evening. Accounts are given of it from Auburn, Cam- 
bridge, Canajoharie, Cayuga, Franklin, Hudson, Lansingburgh, Low- 
ville, Oxford, Pompey, Rochester, Union, Cazenovia, and Utica. 
The second aurora noticed in the Annals, is that of the 20th of 
August. An aurora was also seen in the State of New-York, at 
Lowville, Pompey, Cazenovia, and is particularly described as pre- 
senting an unusual appearance at Utica. 
The next aurora which appeared worthy of a particular notice in 
the Annals, happened on the 7th of September; and the same 
evening an aurora was seen at Lewiston in Niagara county. On 
the 17th of the same month an aurora was also observed in Eng- 
land, and the same time at Pompey, St. Lawrence and Utica. 
Under the report of the meteorology for the month of October, 
in the Annals, two auroras are described as appearing, one on the 
evening of the 5th, and the other on that of the 16th. ‘These were 
both seen in the state of New-York, the first at Utica, and the se- 
cond at Lowville. 
Two auroras are particularly mentioned as appearing in England 
in November ; but no corresponding ones are noticed in the Report 
of the Regents, as having been seen in the State of New-York. 
In the meteorological reports for the month of December, in 
the Annals, there are five auroras mentioned. The most inter- 
esting of these happened on the 11th, and exhibited peculiar ap- 
pearances. At one time, from a segment of the horizon of 70 de- 
grees in extent, there emanated several flame-colored perpendicu- 
lar columns, some of which were 2 degrees wide and 30 in altitude: 
these were succeeded by others, which ultimately exhibited red and 
purple tints. _Many persons. in England saw the aurora, and des- 
cribed it as exhibiting an awful appearance from a mixture of the 
colors. ‘The most brilliant aurora which appeared in the State of 
New York during 1830, happened on the same evening. At Alba- 
ny, it extended nearly 90 degrees around the northern horizon ; and 
at one time, a row of bright columns rose from an arch, and extended 
upwards, some of them nearly to the north star. The columns
