that its particles fliall touch each other ; the fpace 
B/S will be intirely deprived of fluid; and in the 
fpace Cby and all the reft of infinite fpace, the mat- 
ter will be exactly faturated. 
For, if the fluid is difpofed in the above-mentioned 
manner, a particle of fluid placed anywhere within 
the fpace Qb will not be impelled in any dire<ftion 
by the fluid in Bb, or the matter in B{3, and will 
therefore have no tendency to move : a particle 
placed anywhere without the fphere will be at- 
tracted with juft as much force by the matter in B(3, 
as it is repelled by the redundant fluid in Bby and 
will therefore have no tendency to move : a particle 
placed anywhere within the fpace Bb, will indeed 
be repelled towards the furface, by all the redundant 
fluid in that fpace which is placed nearer the center 
than itfelf ; but as the fluid in that fpace is already 
prefled as clofe together as pofllble, it will not have 
any tendency to move; and in the fpace B/3 there is 
no fluid to move, fo that no part of the fluid can 
have any tendency to move. 
Moreover, it feems impoflible for the fluid to be 
at reft, if it is difpofed in any other form ; for 
if the denfity of the fluid is not everywhere the fame 
at the fame diftance from the center, but is greater 
near b than near dy a particle placed anywhere between 
thole two points will move from b towards d ; but 
if the denfity is everywhere the fame at the fame 
diftance from the center, and the fluid in is not 
prelied clofe together, the fpace Cb will be over- 
charged, and confequently a particle at b will be re- 
pelled from the center, and cannot be at reft : in 
like manner, if there is any fluid in B /3, it cannot
