322. Notice of several Meteors. 
The Eastern Argus, printed at Portland, state of Maine, 
says the meteor.was seen in that town at a quarter past 10 
o’clock in the evening of the 9th, in a direction nearly: west, 
its maguitude << that of the moon—its brilliancy very 
great—and when sh ete: — not unlike those 
York. The Bridgeport Courier says, “its size appeared 
to be that of a large artificial globe, and moved with great 
velocity in a direction from northeast to swipe leaving 
a trail of immense size and peculiar brightne 
It is remarked by a Boston Editor that “this meteor must 
have been very large and the sound at its separation louder 
than the loudest thunder, as its explosion was not only seen 
in many opposite places, but heard from Portland, in the 
state of Maine to 60 miles west of Albany. 
A writer in the Albany Daily Advertiser in commenting 
on Mr. Doty’s statement mentioned above, says; 
** Eight minutes was the time between its appearance and 
the report of its explosion, its distance from him must have 
been about one hundred miles, for sound travels about thir- 
teen miles in a minute. From these data we may calculate 
that the place where it was vertical must be about seventy 
miles from Albany in a northwesterly direction, and that its 
size was near a mile in diameter; but to enable us to calcu- 
late with greater accuracy its height, dimensions, and the 
tracts of country over which it passed, observations at ‘places 
to the west as well as to the east of it are necessary.”

The following communication from Professor Dean of 
the University of Vermont has been recently received, and 
we give it in connexion with the preceding communications 
to which it bears an important relation.

Sir, 
The meteor of bas March (1822) has ceased to be the 
subject of general conversation, but it is not the less inter-
