Line you will find, that the Mean Height of the 
Inches. 
Barometer for the whole 14 Years is 29.58; the 
Mean Quantity of Rain annually, 23 Inches; and the 
Mean Altitude of the Thermometer j 5 ^ 8 | that is, at 
the coldeft time of the Day 56, at the hotteft 48, and 
their Mean 52. In the middle Column, viz. that of 
Rain, the Commas , Semicolons , and Colons , over the 
Figures, denote, by their manner of placing, from the 
Left to the Right, what Time in the Month the Rain

made ufe of all along, is that of Mr. Hauksby , and 
kept conftantly in the fame Place, as mentioned by 
Mr .Geo. Hadley in the Tranfaffiions , N° 447. And the 
Altitudes of the Thermometer are taken but twice a 
Day, viz. at the coldeft, which is at Sun-rife, or 
fometimes a little after ; and at the hotteft, viz. 
between Two and Four in the Afternoon: By which 
Method are gained the proportional Heats for every
