A.M. and P.M. Strong gales of wind, 
with rain. 
Between eleven and twelve o’clock A.M . 
fell a shower of rain, mixed with snow, 
by which the rod became rather strongly 
electrified, positively ; which continued 
with some variation of intensity (with- 
out change of kind) near three hours. 
T he greatest divergency of the pith 
balls was four inches, when fine sparks 
were received from the brass ball N. 
Nearly all day. Divergency three-quar- 
ters of an inch. Weather serene. 
The air is extremely moist ; and some 
small rain fell several times this day, 
which was almost void of the electric 
fluid ; for I could not obtain it in quan- 
tity sufficient to ascertain the kind, un- 
til I added a lighted pitch torch to my 
hand exploring-rod. 
The pith balls half an inch open nearly 
all day. 
Five o’clock this morning, a most tre- 
mendous storm of wind, rain, light- 
ning, and thunder, visited London and 
other parts. I, being not well, and in 
bed, did not get up to make observa- 
tions. I thought I heard the bell ring : 
however, the rod was but weakly elec- 
trified the rest of the day. The high 
wind continued, without rain, all day. 
Moderate weather, and nearly a con- 
stant charge of electricity in the rod. 
P.M. A fair morning, and a wet even- 
ing. 
The rod has been electrified nearly all 
day, by a fog. 
A.M. In the evening negative, from a 
fall of rain. This evening much light- 
ning and thunder at Canterbury. 
A.M. A foggy morning. Half an hour 
after eight o’clock P.M. happened a 
sudden gale of wind and rain, by which 
the rod became rather strongly electri- 
fied, negatively.
