motion, and fometimes fudden jerks. 
There were feveral fhowers of rain, 
and two of hail ; during the fall 
of hail, the rod was moft powerfully 
electrified, the bell rang very ftrongly ; 
the effeCts and appearances were fo 
awful, that I kept at a good diftance 
from the rod. A great deal of light- 
ning on the eaft fide of Kent and Effex
