blood, and in the shade of my house only 8° below it. The 
distance between freezing and the heat of human blood being 
divided into 100 parts." 
[The heat of human blood is generally estimated at 90° Fahr. : 
his sun temperature would therefore only be 904 2-° Fahr., and that 
in the shade 85Jy 0 . In the ‘Gentlemen’s Magazine’ for 1750, the 
excessive heat of this month is thus recorded. “The excessive 
heat of July 13th and of the preceding days so affected the fish in 
the Thames, that they gathered in shoals to the bank side, and 
buried themselves in the ooze and mud, and were easily taken in 
great quantities. Loads of fish perished in the fens of Cambridge- 
shire, and one person lost £300 by the death of jacks and pikes.”

showing a startling increase in the number of deaths owing to 
the excessive heat. The average number of the 1st, 2nd and 4th 
week was 345, the hot week shows an excess of 208 over the 
average. This intense heat was followed by severe thunderstorms.] 
“On June 24th and 25th, 1745, a severe storm of thunder and 
lightning happened at the city of Norwich and the places adjacent. 
At Ilorseford, a small country village about four miles N.w. of 
this city, a remarkable phenomenon appeared the next day, the 
like whereof has not been observed in this county since that com- 
municated to the Royal Society by Mr. P. Le Neve. A sudden 
lapsus or sinking down of the earth, happened at this village in the 
night above mentioned, and left a hole 12 feet deep and 12£ feet 
in diameter, in form almost exactly round, its sides nearly perpen- 
dicular, and what seems most strange, no rutiles, cracks, or chasms, 
arc to be found nigh it.”
