On the Meteors of 13th November. 385 
Its altitude might be seven or eight degrees. A little before five 
o’clock, Mr. P. endeavored, with a theodolite, roughly to divide the 
great circle, which passed through the radiating point and the north 
and south points, into definite spaces. Of those meteors that marked 
their path on the sky, none descended below an altitude of 37°. 
Those which fell into the space rising 20° above this, were of a red- 
dish hue, and had longer trains than any others. These trains sub- 
tend an angle of 40°, meteors of the same altitude having trains of 
uniform length. In the next space above (57°—77°) the meteors 
were of a paler hue, but more in number. In the third space of 
25°, (77° N.—12° S.) which reached to the confines of the ciréu- 
Jar space above mentioned, the meteors were white, their trains short, 
and number greatest of all. These observations were made on the 
northern arc ; no measurements were made on the southern side, but 
he judged the phenomena to be the same, except that the meteors 
were not so numerous as on the northern side. 
From these and various other d before us, we proceed to ar- 
range and classify the principal facts so far as they are ascertained ; and 
as these must form the basis of all correct reasonings on the nature and 
origin of the meteors, it is deemed advisable to make the collection 
very full, to state them, generally, in the language of the narrator, 
and to indicate the sources whence they are derived, not only as 
vouchers for their accuracy, but for the purpose of enabling readers 
who may desire it, to have recourse to the original statements. 
If. Synopsis or THE Facts. 
1. WeatHer.—Throughout the entire region where the Meteors 
were observed, there was a sudden and extraordinary change of 
weather from warm to cold, accompanied by an uncommon transpar- 
ency of the atmosphere. 
(1.) Boston.—The  . yesterday at 2 P. M. was 63°; 
this morning at 4 o’clock, it was 39°. There was litle wind, and 
is from the west. (Columbian ‘Ganwaet: ) 
(2.) Hartford, Con.—The day preceding, it rained, and the air 
was very mild, the wind at the S. E. In the evening, the wind 
changed to the N. W. and it came off bg clear and cool, 
temperature 31°. (Independent Inquirer 
“ .) Philadelphia.—The sky was clear, stars shining brilliantly, 
and wind high. (National Gazette.) 
(4.) Annapolis, Md.—The heavens exhibited an aspect to gladden 
the heart of the astronomer. ‘The winds were hushed; the whole 
firmament was absolutely cloudless; and all a starry host twinkled 
with a dazzling lustre. (Saml. B. Smith, M. D.)
