and In like manner there will be a'great deh- 
cience of fluid in e (p. But in order to form fome 
eflimate of the proportion «of the redundant fluid, 
which will be lodged in let the communication 
betw^een Eyand the ground be taken away, as well 
as that by which is eleflrified ; and let fo much 
fluid be taken from BS", 'as to make the redundant 
fluid therein equal to the deficient fluid in E (p. If 
we.fuppofe that all the redundant fluid is colledled 
and all the deficient in e<p, fo as to leave 
and E^/faturated; then, if the ekaric repul- 
fion^ is inverfely as the fquare of the diflance, a 
particle of fluid placed anywhere in the plane 
except near the extremities l> and will be at- 
trafted with very near as much force by the redun- 
dant matter in e cp., as it is repelled by the redun- 
dant fluid in^S; but if the repulfion is inverfely,. 
as fbme higher power than the fquare, it will be 
repelled wi|h much more force by than it is- 
attracted by e (p, provided the depth b j3 is very 
fmall in refpedl of the thickncfs of the glafs ; and 
if the repulfion is inverfely,. as fome lower power 
than the fquare, it wnll be attraded whth much 
more force by e(p, than it is repelled by Hence 
it follows, that if the depth to which the fluid can 
penetrate is very fmall in refpedt of the thicknefs^ 
of the glafs, but yet is fuch that the quantity of 
fluid naturally contained in or c(p, is confi- 
derably more than the redundant fluid in B then* 
if the repulfion is inverfely as- the fquare of the 
diflance, almo-fl; all the redundant fluid will be 
collected in bd, leaving- the nlacc .B J not very 
much, overcharged and in like manner Kf vyfll be.:
