into a negative ft ate, had drawn from the metal itfelf. 
And thus it will appear, that the glafs had, in the dif- 
charging, by no means parted with that ftate of electri- 
city which it had acquired by the force of charging. 
Now, glafs and all eleCtric fubftances receiving with 
more difficulty a ftate of electricity, and parting with it 
with more reluctance, the confequence muft be, that,, 
when the two coatings are feparated from the glafs, fo as 
not to be in the way of abfor bing or lofing the eleCtric fluid 
by other conducting bodies being near them, the upper 
coating, which was pofitive when the glafs was charged, 
and nearly in its natural ftate, when after the dif- 
charge it remained in conjunction with the glafs, muft.

the other coating) in a natural ftate when after the

becaufe it had abforbed a quantity of eleCtric fluid in the
