If AD is overcharged, and EH undercharged, 
and the redundant fluid in A D is exadly fufficient 
to faturate the redundant matter in E H, all the re- 
dundant fluid in AD will be colledted in the fpace 
C D, where it will be prefled clofe together : the 
fpace EF will be intirely deprived of fluid, the quan- 
tity of matter therein being juft fufftcient to faturate 
the redundant fluid in G D, and the (paces A C and 
F H will be everywhere faturated. Moreover, if an 
opening is made in the planes ha or H the fluid 
within the fpaces AD or E H will have no tendency 
to run out thereat, nor will the fluid on the outfide 
have any tendency to run in at it ; a particle of fluid ' 
too placed anywhere on the outfide of both fpaces, 
as at P, will not be at all attradled or repelled by 
thofe fpaces, any more than if they were both fa- 
turated ; but a particle placed anywhere between 
thofe fpaces, as at S, will be repelled from d to- 
wards e i and if a communication was made between 
the two fpaces, by the canal de, the fluid would 
run out of AD into EH, till they were both fa- 
turated.
