clofe at the approach of excited wax. 
Half paft: two, P. M. The fame as at eleven 
o’clock. Three o’clock. Over-call and cloudy " 
the balls are very Hill, but fhew fcarce any fign of 
eledtricity. 
Feb. ii. Eight o’clock, A.M. A thick fog 
is fenfibly eledtrified poftively. The balls diverge 
a quarter, or three eighths, of an inch. Wind 
S. W. and troublefome. Thermometer 38. Ba- 
rometer, 29,94. 
Feb. 15. Half paft ten, A.M. I find a thick 
fog, fenfibly eledtrical. The balls diverge five- 
eighths of an inch, full. Prefently, after I had 
fixed my rod, there fell fome fmall drops of rain* 
Upon the moment of its falling, the balls increafed 
their divergence near, or quite, a quarter of an 
inch. I never faw a fog more ftrongly eledtrified 
when the weather was fo warm, the mercury in 
my thermometer, in the open air, being feven and 
an half degrees above the freezing point. I fup- 
pofe higher in the atmofphere it is now uncom- 
monly cold. 
Fifty minutes paft two, P. M„ It fnows very faft„ 
The air is now ftrongly eledtrified poftively. The 
balls feparate full three quarters of an inch. 
Wind S. W. 
From the fmall number of experiments I have 
been able to make, on the eledtricity of the atmo- 
fphere, I cannot help being of opinion, that fogs 
are much more ftrongly eledtrified in, or immedi- 
ately after , a frof , than at other times ; and that 
the eledtricity in the fogs is often the ftrongeft,
