long feather broom, and gently swept 
the rod down ; on examining the broom, 
I found a spider’s web entangled in the 
feathers. I then went down to the appa- 
ratus, and found the pith balls a quarter 
of an inch open positive, which gradu- 
ally increased, even to visible sparks. 
Six o’clock A.M. I found the electric

charge in the rod much weaker than 
when I left it last night. Nevertheless, 
when the sun got up a little above the 
horizon, the rod became stronger elec- 
trified. The pith balls never closed this 
day. 
The operations of the rod to-day have

I found the pith balls closed. Atmo- 
spheric electricity has been more variable 
this day than for many days past; some- 
times quite null, then weak, or strong 
by turns, until three o’clock P.M. when 
it again became constant during the re- 
mainder of the day. 
Six o’clock A.M. I found the pith balls

open full three quarters of an inch po- 
sitive, and they continued open all day. 
Their least divergency (as usual) about 
midday. The weather still thick and 
dark in the forenoon ; and clear serene 
weather in the afternoon. 
Six o’clock A.M. I found the pith balls

opened near one inch and a quarter ; 
and they neVer closed this day. Their 
least divergency, as usual, was about 
midday, and their greatest was near 
midnight. Weather serene. 
Six o’clock A.M. I found the pith balls 
nearly closed, and the state of the air 
moist and foggy. Half after seven 
o’clock, the balls opened a little wider, 
and continued to increase in strength, 
so that between eleven and twelve 
o’clock their divergency was full three 
inches. I saw nothing in particular to 
occasion ir ; and I thought it was above 
the intensity of common serene weather. 
I saw indeed a dark cloud, but it was
