To Mr. H. Baker F. R. S. of extraordinary 
Heat in Feb. and of the fame Earthquake. 
Dear Sir , 
Read March 8. f a \HE Temperature of the Air was 
‘749 5°* found to be warmer by mv Ther* 
mometcr (abroad) feveral Days of the laft Month 
at 2 h p. m. than I had obferved it to be fome Days 
in June laff, at the fame Hour ; but, on Thurfday 
Feb. 22. at 2 h p. m. it hood at near 63 j and loon 
after rofc to 63 full ; which is higher,- as appears 
from my Rcgifttr, than it was at the fame Timex>f 
Day, 18 Days in the Month of “June. And I find, 
by an Account fent me from Mr. Canton , of Spital- 
Square, that his Thermometer was at the fame De- 
gree at 2 h p. m. the fame Day. 
This perhaps may be thought riot unworthy to 
be regifter’d in the meteotological Accounts in the 
Thil. Tranf. but is fubmitt^d to the Judgment of 
the Royal Society , by " 
Tour and their rnofl obedient , 
Doting, March 8. 
1749-50. hrnble Servant , 
H. Miles. 
y, S. I was this Morning, at y* 40' furprifed with a 
violent Shock in my Study, which fhook the 
Doors of my Book-Prelfes exceedingly : It was 
felt all over this Town and the next. I have not 
Time for further Particulars, nor am I able to fay 
as yet, whether it was caufed by the blowing up 
of a Powder-Mill, or by an Earthquake.
