day has been so weak, that I have been 
obliged to content myself with obtain- 
ing the kind by a pair of flaxen threads, 
without balls to them. The weather 
warm and showery. 
{ The operations in the rod, these two 
days, have been of the periodical kind. 
See 17th of October. 
Pith balls not open this day. The kind 
was obtained by flaxen threads without 
balls to them. A moist air. 
Sharp dark weather, with a dry east- 
erly wind ; and a weak electricity. 
The severe easterly wind is now gone, 
and a more intense atmospheric elec- 
tricity is returned. Nine o’clock A.M. 
a large black cloud passed over the rod, 
and a moderate shower of rain fell, by 
which the rod was rather strongly elec- 
trified negatively. This shower lasted 
one hour ; and near the middle of it, the 
electricity changed to a strong posi- 
tive ; after this, the electricity ended as 
it had begun, negative. 
By the night bottle. Half an hour after 
two o’clock P.M. fell some rain, and 
the rod became electrified negatively. 
At Calstock, in Cornwall, in the even- 
ing of this day, much lightning and 
thunder. 
Half an hour after midday, fell a mo- 
derate shower of rain, attended with a 
great darkness. The rod now became 
rather strongly electrified negatively ; 
and the bell rang weakly. There were 
after this several showers, which only 
gave a weak positive electricity ; except 
one, which fell at ten o’clock at night ; 
this indeed was strongly positive. At 
eleven o’clock this night, both at Lon- 
don and Portsmouth, there was much 
lightning and thunder. And also, at the
