Degrees of Fahrenheit's Thermometer 5 and the 
greatcft Decreafes of Heat, in the fame Spaces of 
Time, in thole Seafons, were 35, 32 , 27 and 27 
Degrees refpe&ively. It frequently happens, that 
one Day is ten or more Degrees warmer than the 
preceding Day 5 but the Decreafes of Heat are al- 
ways greater and more fudden than its Increafes* 
On the 10th of January 1745. at 2 p. m. the Mer- 
cury in the Thermometer was at 70 ; next Morn- 
ing it had funk to the 26 th Degree? and on the 12 th 
Day in the Morning it was at 15, which was the 
greateft and moft fudden Change I have feen. 
In Summer, the Heat of the fhaded Air, about 2 
or 3 in the Afternoon, is frequently between 90 and 
95 Degrees? and on the 14 th , 15 th , and 16 th of 
June 1738, at 3 p. m . it was 98 ? a Heat equal to 
the greateft Heat of the human Body in Health. In 
Winter I never but once faw the Thermometer fo 
low as 15 : Therefore the Difference between the 
moft intenfe Heat and Cold of the fhaded Air, in 
this Province, is 83 Degrees j which is a much 
greater Range than could well have been expe&ed 
in this Latitude? and taking the Mean between thofe 
Extremes, 5 6 fhould be the temperate Degree of 
Heat in this Province : But the Sum of the thermo- 
metrical Altitudes, divided by the Number of Ob- 
fervations which I made for fome Years together, 
gives 66, which may therefore more juftly be rec- 
koned the temperate Heat in Carolina , which ex- 
ceeds 48, the temperate Heat in England \ more than 
that exceeds the freezing Point,
