set the wind W, when heavy black 
clouds were forming, their upper border 
about 25 degrees above the horizon. 
The lightning flashed among these 
clouds from nine to eleven o’clock. But 
there being neither clouds nor low va- 
pour near the rod, it was not affected 
thereby. In the evening of this day at 
Salisbury, a very severe storm of hail, 
rain, lightning, and thunder.

At the same time, in a loxver stratum of 
air, the hand exploring rod was elec- 
trified positively. Abundance of small 
white clouds passed over the rod, which 
kept the pith balls continually clos- 
ing and opening, with negative elec- 
tricity. Eight o’clock P.M. some 
heavy drops of rain fell ; the rod now 
‘ became very strongly electrified ; the 
bell rang slowly, and soon stopped, 
while the electricity changed to a strong 
positive, then rang again more briskly 
for a longer time. After this there were 
two more gradual changes. 
The weather, and atmospheric electri- 
city, have been this day nearly the same 
as on the preceding one ; only the opera- 
tions in the rod have been more power- 
ful. For in one charge of the rod to- 
day, I counted about forty dense sparks, 
which spontaneously struck between
