PROP. VI., 
Pros. 2. To determine in what manner the fluid 
will be difpofed in the globe BDE, fuppofing 
every thing as in the lafl: problem, except that 
the fluid on the outlide of tlic globe is immove- 
able, and difpofed in fuch manner as every- 
where to faturate the matter, and that the elec- 
tric attrad:’lion and rcpulflon is inverfely, as 
fomc other power of the diflance than the 
fquare. 
I am not able to anfwer this problem accurately; 
but I think we may be certain of the following cir- 
cumftances. 
Case i. Let the repulflon be inverfely as fome 
f>ower of the diflance between the fquare and the 
cube, and let the globe be overcharged. 
It is certain that the denfity of the fluid will be 
everywhere the fame, at the fame diflance from the 
center. Therefore, firfl, There can be no fpace as 
C within which the matter will be everywhere fa- 
turated j for a particle at b is impelled towards the 
center, by the redundant fluid in and will 
therefore move towards the center, unlefs Qh is fuf- 
ficiently overcharged to prevent it. Secondly, The 
fluid clofe to the furface of the fphere will be prefl'ed 
clofe together ; for otherwife a particle lb near to it, 
that the quantity of fluid between it and the furface 
Ihould be very fmall, would move towards it ; as 
the repulflon of the flnall quantity of fluid between
