VI. An Account and Abjlraff of the Meteo- 
rological Diaries communicated to the Royal 
Society, for the Tears 1719 and 1730. 
By Geo. Hadley, Efq $ F. R. S. 
T HE Society having been pleas'd to refer to me, 
on the Death of Dr. j Derham, the Meteoro- 
logical Diaries tranfmitted to them from the curious 
Obfervers both at Home and in foreign Parts 5 as foon 
as they were put into my Hands, I apply'd myfelf to 
make an Abftraft of them in fuch Manner as I judg'd 
may be moft ufeful, and have nearly purfued the Me- 
thod of Dr. c Derhara y beginning at the Year 1725X, 
where he left off. [See thefe Tranfattions^ N° 43 y.] 
Before I proceed to the Tables, I think it proper to 
give fome Account of each of the Diaries of thefe 
two Years, and their Contents, that any Member of 
the Society, that may have Occafion to make farther 
Inquiries into thefe Matters, may be acquainted what 
is to be found therein, and what Pains have been be- 
llowed by the curious Obfervers. 
The Diary kept by Mr. Hauksbee , by Order of the 
Society, at their Houfe in Crane-Court , confifts of Ob- 
fervations of the Barometrical Heights twice a Day, 
i. e . Morning and Evening, in Inches, Decimals and 
Centefimals ; the Thermometer likewife, in its pro- 
per Graduations, which, I fuppofe, are already well 
known to the Curious, and the Weather, with the 
Hour of each Obfervation. The Winds are omitted. 
The Depth of Rain is fet down feveral times for the 
moft part in each Month, the Sum of which is to be 
divided.
