JVotice of the Weather. 

 The morning of this day was cloudless, with tbe wind blow- 



r 



ing from N. "W ; but, during tbe phenomena, the vapor in the 

 air was condensed with unusual rapidity in the south. About 30 

 minutes after 10 o'cl. the southern part of the halo BOIN began 

 to be obscured by clouds ; and about 2 o'cl. P. M. snow began to 

 descend with the wind blowing from the S. E. The form of this 

 snow was rather uncommon ; it was that of very long and slender 



spicula or prisms. 



Two days previous to this phenomenon, rain had fallen with 

 a south wind; but the day, immediately preceding the 17th, was 

 fair with a N. W. wind, and so cold, that the maximum of heat 

 was only di". Indeed on the 17th, the thermometer rose no high- 

 er, than 31" ; and the following day was cloudy and cold with 

 the wiud from N. \V. During the nights of the 21st and 23d of 

 March, the thermometer descended a little below zero, a degree of 

 cold very uncommon at that season. From the 17th of March to 

 the 14th of April, there were eight distinct falls of snow at Bruns- 

 wick. 



13. Vaughan esq. of Hallowell, repeatedly observed, during 

 the month of March, that, in the region, where the sun was shin- 

 ing, the atmosphere exhibited an unusual aspect. The appear- 

 ance about the sun seemed to be such, as would result from 

 coveriug the sky with an extremely thin semitrausparent mist, 

 composed of black and white vapors, illuminated from within^ 

 and, at the same time, coated without by a transparent, silvery 



varnish. Tbe black tint was once or twice very conspicuous.
