1750 JL m y Obfervations on the late hot 
Weather; which, for 12 Days part, has been here at 
Norwich the molt exceflive I ever knew. The Be- 
ginning of this Heat was on the 8th of this inftant 
July ; on which (tho’ the whole Day was cloudy) 
the Ground was fo uncommonly hot, that I could 
not bear to walk on it long together without much 
Uncafinels; and many were fenfibie of the fame 
Inconvenience as well as myfelf. 
On JVednefday the nth, which was the hottefl: 
Day of all, my Thermometer in the Sun’s Rays flood 
11 Decrees above the Heat of human Blood; and 
in the Shade, in my Houfe, only 8 Degrees below 
it. The Diflance between Freezing and the Heat of 
human Blood being divided into 100 Parts. 
An Inch of Tallow, of an Inch in D ameter, 
liquefied in the Sun in lefs than 30 Minutes. A Piece 
of Refin, of an Inch in Diameter, became fo foft 
as to be liable to take any lmprefiion in the fame 
time.
