not very much undercliarged : if the repulhon is 
riiverfely as fome higher power than the I'quare, 
will be very much overcharged, and Kf very 
much undercharged : and if the repulfion is in- 
verfely, as fome lower power than the Iquare, Yjd 
will be very much undercharged, and Kf very 
much overcharged. 
Suppofe, now, the plate to be feparated from 
the plate of glafs, ftiil keepiiig it parallel thereto, 
and oppofite to the fune part of it that it before was 
applied toj and let the repulfion of the particles be 
inverfely, as fome higher power of the diflance than 
the fquare. When the plate is in contaft with the 
glafs, the repulfion of the redundant fluid in that 
plate, on a particle in the plane b d^ td (ji, the inner 
lurface of the plate, mud be equal to the excefs of 
the repulfion of the redundant fiuid in- bl on it, 
above the attradion of E on it ; therefore, when 
the plate B ^ is removed ever fo fmall a diftance 
from the glafs, the repulfion of the redundant fluid 
' in the plate, on a particle in the inner furface of that 
plate, will be greater than the excefs of the repuliion 
of b^on it, above the attradion of E <p; for the repul- 
iaon of b^ will be much more diminifhed by the re- 
moval, than the attradion of E<p : confequently, 
fome fluid will fly from the plate to the glafs, in the 
form of fparks : fj that the plate will not be lb much 
overcharged when removed from the glals, as it was 
when in contad w'ith it. I fhould imagine, however, 
that it would dill be confiderably overcharged. 
If one part of the plate is feparated from the glafs 
before the red, as mud neceflarily be the cafe, if it 
conlids ot bending materials, I Ihould guefs it would
