AURORA BOREALIS. 



On Monday night, December 1st, an aurora borealis was ob- 

 served here at intervals from six o'clock till after midnight. It first 

 rose in the N.W. in the form of a segment of a circle cut by that 

 part of the horizon, showed a bright flame-colour about twelve de- 

 grees high, and disappeared at half past six. At seven it again ap- 

 peared, brightest about the magnetic North, when seven or eight 

 light red coruscations or columns of light rose from it perpendicu- 

 larly, nearly due North, to an altitude of twenty degrees ; and se- 

 veral small meteors fell in that quarter. At a quarter before eight 

 it again disappeared, and reappeared at ten, when several columns 

 of light rose from its base, and it continued more or less bright till 

 after midnight. 



Its disappearing as above stated, may be attributed to the effect 

 of an upper current of wind from the S.W., as ascertained by the 

 motion of black clouds from that quarter. A very hard gale blew 

 next the earth from the N.E. through the evening and night, with 

 a sudden rise of the mercury in the barometer.
