This morning fell a warm drizzling rain ;

which seems to have acted like a charm 
on the late constant electrification of 
the atmosphere : for I find it so weakly 
electrified since the rain fell, that 1 was 
obliged to connect, with the rod, a 
lighted torch, to ascertain the kind. 
Four o’clock this morning, a severe 
storm of wind and rain, driving full 
against my bed-room window, induced 
me to rise from my bed to see the state 
of the rod ; which I found highly elec- 
trified, positively. This wind did not 
abate its force till sun -set. Four o’clock 
P.M. some rain fell, mixed with snow, 
which lasted near one hour. During 
this time the rod was most powerfully 
electrified positively : I counted seven teen 
spontaneous explosions between the 
brass ball and bell, notwithstanding the 
bell was ringing all the time. Half an 
hour after five o’clock, came a se ond 
shower of rain, hail,- and snow, which 
lasted half an hour, attended with un- 
common darkness. Daring about half 
this time, the electric charge in the rod 
was as strong as it could possibly be'; 
for the fluid almost streamed between 
the brass ball anu bell : I counted near 
two hundred very brilliant explosions 
between the ball and bell. The bell 
rang all the time. This latter very high
