clouds frequently passed over the rod, 
by which it became electrified nega- 
tively. When they passed somewhat 
nearer, and dismissed some large drops 
of rain, the rod then became highly 
charged, and the bell rang briskly, and 
continued its ringing near half an hour. 
The pith balls were very much agi- 
tated, sometimes with a pendulous mo- 
tion, then started closer or wider asun- 
der several times. But the most extra- 
ordinary phasnomenon of to-day is, that 
the rod continued ten hours electrified 
negatively, without change of kind : 
during that time the pith balls never 
closed.

yesterday, when compared, appear to 
have but little resemblance. This day 
the electricity has changed four times, 
and the bell rang briskly for a minute 
or two between each change of electri- 
city.

shower of rain fell, by which the rod 
became electrified positively, but soon 
changed to negative. The bell now rang 
weakly one minute, and then stopped 
while the electricity changed to posi- 
tive, which soon changed again to ne- 
gative. The electricity and the weather 
have been much varied to-day. At New- 
Mills, in Scotland, some lightning and 
thunder. 
The weather this day has been rather 
more varied than yesterday, with a con- 
tinued succession of showers and sun- 
shine : and the atmospheric electricity 
has been considerably more intense, and 
constant. There have been five gradual 
changes of electricity ; between four of 
those changes, the bell rang briskly. 
The pith balls also exhibited some of 
their curious agitations ; one jerk in
