[Feb. 



hurricane, or some other convulsion of nature, was followed by a 

 cloudy morning, with a strong wind from the north-west : at 

 nine o'clock the weather cleared up, and continued fine until the 

 going down of the sun, which set in a bank of dense clouds. The 

 next day the wind came round to the east with rain. On the 

 28th of December at 9'' 30', p.m. the barometer stood at 27*8 

 inches, the wind blew very fresh from the SE, and the subsequent 

 day it was light from the NW, with rain. It is remarkable that 

 in the year there has not been a calm day at Bushey Heath, and 

 in the stormy days of November and December, the wind was 

 particularly unsteady ; nearly calm at intervals, followed by 

 violent gusts — a proof that the cause of the wind was constantly 

 fluctuating. I remain, dear Sir, truly yours, 



Mark Beaufoy.

SIR, Plumstcad, near Woclwich, Dec. 17, 1821. 



The first idea of the following experiments was suggested to 

 me on reading sometime since a paper by Mr. Scoresby, pub- 

 lished in the Edinburgh Philosophical Journal, No. 8, and an
