On the Heat of the Weather at Tooling, in July and September last. [1750] 

 By the Rev. Henry Miles, F.R.S., D.D. N° 496, p. 571. 



The morning at 4, July 11, had nothing remarkable : at 2 p.m. the heavens 

 mostly clear, and no indications of a storm ; the barometer having fallen but -pf-j- 

 inch since 4 a.m. it then stood at 30, 20. the thermometer at &7-L, and before 

 .3 p.m. at 88^, which is the hottest temperature of the air he ever knew. At 4 

 p.m. was very distant thunder; soon after it came a little nearer, and was one 

 continued murmur, without any perceivable intermission for great part of an 

 hour : the lightning accompanying it, not much. The wind was nearly s.w. 

 and dark clouds passed by on each side till they united in the n. forming one of 

 the blackest clouds he ever saw, over the city, as near as he could guess. They 

 had not one drop of rain, nor did there fall either rain or hail for near 3 miles to 

 the N. of the place towards London : a few hail-stones it seems fell in some parts 

 ofClapham. 



The barometer fell little, and the thermometer no more than usual at that 

 time of the evening. Mr. Canton writes that his thermometer in Spital square 

 (of the same construction, and kept too in the open air) fell no less than 17 

 degrees. 



At 4 a.m. Sept. 2, the wind being easterly, and blowing strong, accompanied 

 with several short showers of rain, the barometer being at 29.97, the thermo- 

 meter abroad stood at 61 : a degree of heat exceeding any he had taken notice of 

 during the whole summer at that time of the morning. 



On the Hot JVeather in JulyllbO, dated Norwich July 23. By Mr. fVm. Jrderon, 



F.R.S. N°49(), p. 573. 



For 12 days past, the weather was at Norwich the most excessive ever known. 

 The beginning of this heat was on July 8th ; when, though the whole day was 

 cloudy, the ground was so uncommonly hot, that Mr. A. could not bear to walk 

 on it long together without much uneasiness ; and many others were sensible of
