A.M. The pith balls closed and opened, 
without change of kind, several times 
this day : and they have been veiy irre- 
gular when compared with many of the 
preceding. A thin wet fog has pre- 
vailed all this day.

small sparks. When the rain was over 
the rod was electrified positively, and it 
continued so.

of the periodical kind. The pith balls 
never closed. 
Near six o’clock A.M. I found the pith

left them last night. Half an hour after 
ten o’clock, fell a heavy shower of rain : 
the pith balls now closed, and soon 
opened negative, which, with the rain, 
continued for the rest of the day.
