XII. A Letter from Dr. John Lining to 
C. Mortimer M. D. Sec . R. S. concerning the 
Weather in South-Carolina ; with Ah- 
firaSis of the tables of his Meteorological 
Obfervations in Charles-Town. 
SIR , 
Read May 6. r | ^HO’ I have not the Pleafure of a 
17 4 ' JL perfonal Acquaintance with you, 
yet as you are one of the Secretaries to the Royal 
Society , I take the Liberty to fend you fome Tables 
and Obfervations deduced from a Diary of the Wea- 
ther, which I have kept for fome Years paft in this 
Town, which you may communicate to the Royal 
Society , if you think they will be acceptable. As 
an Account of the Inflruments which I have ufed, 
and their Situation, is already publifhed in the Philo- 
fophical Tranfaftions *, I fhall not trouble you with 
a Repetition of thofe Affairs. 
The Viciflltudes of the Weather, with refped to 
Heat and Cold, are perhaps no-where greater than 
in Carolina $ and our Summer’s Heat is probably 
not inferior to that under mod Places of the Equa- 
tor ; nor is our Winter’s Cold much lefs at fome 
times than that in Britain ♦ 
From near eight Years Obfcrvation, the greateft 
Increafe of the Heat of the Air, which I have dif- 
cover’d in 24 or 30 Hours, in Spring, Summer, 
Autumn, and Winter, was 19, 24, 13, and 16 
Degrees
