The author having detached the plates 
A and B before the explofion, found that 
the plate A was pofitively electrified on 
both fides, and the plate B negatively 
electrified on both its furfaces likewife. 
When he feparated the fame plates after 
the explofion had taken place, the elec¬ 
tricities appeared quite oppofite, that is 
to fay, the plate A was electrified nega¬ 
tively on both fides, and the plate B po- 
fitively. Phil. Tranf. 
In the experiment of Lane, the refult 
was the fame with regard to the electricity 
of the plates examined before, and after 
the explofion, as in the experiment of 
Beccaria. 
But Lane placed the two furfaces which 
were not coated in contaCt with each other, 
and having coated the two outer ones, 
and charged them by means of the ma¬ 
chine as a fingle plate, he placed one of 
them fo as to touch the prime conductor, 
whiHl he touched the other with his finger.
