The morning of this day was frosty, and 
the evening wet. The electricity or the 
former was positive, and the Litter ne- 
gative. 
P.M. Balls three-quarters of an inch 
open. Strong gales of wind, with rain. 
Nine o’clock P.M. severe lightning and 
thunder at Falmouth. 
} Very fine weather. Divergency of the 
pith balls has been between null and 
near one inch open. 
Eight o’clock AM. I saw a large black 
cloud in the N and NW : soon after, a 
strong wind suddenly sprang up, and a 
little rain fell; during which, the rod 
was rather strongly electrified nega- 
tively, with small sparks. This charge 
of the rod only lasted eighteen mi- 
nutes. 
1 Fine weather, and almost a constant 
/ electricity. 
P.M. A very high wind, and a weak 
electricity, in the evening of this day, 
much lightning and thunder at Ply- 
mouth. 
P.M. from-a shower of rain. 
I Very moderate weather, and a weak 
f electricity. 
V From rain', with a strong wind. 
The weather for these twelve days hav- 
ing been moderate, the electricity of 
> the atmosphere has only been of such 
intensity as is common to serene wea- 
ther. 
P.M. from a shower of rain, of large 
drops ; the rod became electrified rather 
strongly positive, and emitted fine bright 
sparks at the brass ball N.
