I. 
TDear Sir , 
/«iNov. 22.Tr SEND you a brief Account of the State 
of the W eather, in this Place, on the 
nth Inftant, when the remarkable Storm happened; 
which, if you think fit, may be communicated to 
the Royal Society , when they meet; as there will 
probably be other Particulars relating to it fent in. 
The Morning at 4 had nothing remarkable: At 
2 p. m. the Heavens moftly clear, and no Indications 
of a Storm ; the Barometer having fallen but-j-l^ Inch 
fince 4 a. m. it then flood at 30, 20. the Thermome- 
ter at 877, and before 3 p. m. at 88^, which is the 
hotteft Temperature of the Air I ever knew. 
At 4 p.m. we had very diftant Thunder; loon 
after it came a little nearer, and was one continued 
Murmur, without any perceivable Intermifllon for 
great Part of an Hour: The Lightning accompany- 
ing it, not much. The Wind was nearly S. W. 
and dark Clouds pafled by on each Side of us till 
they united in the N. forming one of the blackeft 
Clouds I ever faw, over the City, as near as I could 
guefs. We had not one Drop of Rain, nor did there 
fall either Rain or Hail for near 3 Miles to the N. 
of us towards London : A few Hail-ftones, I am in- 
formed, fell in fome Parts of Clapham 5 what the
