Let A D be that fpace which contains the 
greateft quantity of redundant fluid, if both fpaces 
are overcharged, or which contains the lead redun- 
dant matter, if both are undercharged j or, if one is 
overcharged, and the other undercharged, let A D 
be the overcharged one. Then, firft, There will 
be two fpaces, A B and G H, which will either be 
intirely deprived of fluid, or in which the particles 
will be prefTed clofe together ; namely, if the whole 
quantity of fluid in A D and E H together, is lefs 
than fufflcient to fatqrate the matter therein, they 
will be intirely deprived of fluid ; the quantity of 
redundant matter in each being half the whole re- 
dundant matter in AD and EH together: but if 
the fluid in A D and E H together is more than 
fufflcient to faturate the matter, the fluid in A B 
and GH will be prefled clofe together; the quantity 
of redundant fluid, in each being half the whole re- 
dundant fluid in -both fpaces. 2dly, In the fpace 
C D the fluid wjll be prefled dole together ; the 
quantity of fluid therein being fuch, as to leave jufl: 
enough fluid in BC to faturate the matter therein, 
3dly, The fpace EF will be intirely deprived of 
fluid ; the quantity of matter therein being fuch, that 
the fluid in F G flaall be jufl: fufflcient to faturate the 
matter therein : confequently, the redundant fluid in 
C D will be jufl fufflcient to faturate the redundant 
matter in EF ; for as AB and GH together con- 
tain the whole redundant fluid or matter in both 
fpaces, the fpaces B D and E G together contain 
their natural quantity of fluid ; and therefore, as 
BC and FG each contain their natural quantity of 
fluid, the fpaces CD and EF together contain their 
natural
