All May the Range of the Barometer was be- 
tween z 3 and 29 Inches; and for the moft part above 
29.50. The Thermometer was on the ill Day at 
52.8, and continued riling to 50 on the 7th, where 
it flood to about the i4th,and then arofe to 40 for the 
following Days, being at 40.25 on the 17th in the 
Morning, Wind S\ and fair, when in the Evening of 
the fame Day it arofe to to 30.34, Wind W*. with 
Rain j it foon got down again to 40 for feveral Days; 
but from the 27th to the End it was about 30.50. 
This Month had much more Fair than any of the pre- 
ceding Months, together with fome Cloudy with 
Showers, and fome heavier Rain. 
In 'June the Range of the Barometer was (as in 
the laid Month) between 28 and 29 Inches, but more 
frequently under 29.50 than it was in that Month. 
The Thermometer was all this Month between 40 and 
and 41, only on the ift, 2d, 3d, 8th, nth, 13th, 
23d Days, it was a little above 31, but never fo 
high as 30, which is between warm Air, and Hot. 
On June 2, Rain fell with Hail. And (as I have 
obferved in fome of thefe Papers) that Cold in Sum - 
mer produces Rain , fo much Rain fell on June 5 ; 
after which,' fome Cloudy, with frequent Showers, 
and many Days fair, to June 23, on which the Ob- 
fervations end. 
Thus I have given an Abftrad of the Meteorologi- 
cal Ohfervations at Petersburg!?, and have taken 
what Care I could to note fuch Matters as may give 
the Society a juft Notion of the State of every Month 
at that Place, and that which was moft obfervable 
in it. I could with, that either the Society, or I my- 
felf could have had fome Obfervations in the more 
Southerly Parts, to have tallied with thefe.
