five o’clock appearances were dread 
ful ; in five minutes time the firong 
gale of wind became a ftorm from 
SE. This florin , of wind (for there 
was but little rain) carried the huge 
black clouds to the N<W, for there I 
faw abundance of red lightning a little 
above the horizon, and i once heard a 
rumbling of thunder. The rod be- 
fore the ftorm was- pofitive, but by it 
was changed to negative, and conti- 
nued fo during the- whole time. . The 
ele&ricity of the rod often varied in 
flrength, fometimes weak, fometimes 
firong, without change of kind. At 
Amerfham, in Berkfhire, and at the 
fame time at the Earl of Aylesford’s 
park, near Packington, in Warwick- 
shire, was a moil tremendous fiorm 
of hail, rain, lightning, and thunder, 
from 4 to 6 o’clock P.M. 
P.M. There were four gradual changes 
of the eledtricity in two hours.

By the night bottle. 
Weak figns; balls not open. A dark

A.M. There were feveral heavy clouds 
pafied from the SW, by which the rod 
was highly charged with pofitive eledtri- 
city.The bell rang brilkly. This charge 
lafied from a little before eleven o’clock!
