All day. The fog fail continues. I 
have obferVed, during thefe three days 
and three nights (abating a little time 
for deep, and which I curtailed for fo 
noble a purpofe), that a foggy va- 
pour was conftantly electrified pofi- 
tively. The pith balls diverged from 
a quarter to three quarters of an inch, 
except when the fog (which was gene- 
rally moderate) fuddenly became thick 
and dark j then the bails would open 
to near two inches ; at thofe times I 
received the electric fluid into bottles. 
This fog began ftrongly negative.
