Corollary. 
In like manner, if B is made undercharged, fome 
fluid will flow from D to A, and alfo from that part 
of A near RS, to the part near MN. 
PROP. XIII. 
Suppofe now that the bodies A and D com- 
municate by the bent canal M P N « ^ 
(fig. 7.) inftead of the ftraight one EF : let the 
bodies be either faturated or over or undercharged 
as before ; and let the fluid be at refl: ; then if 
the body B is made overcharged, fome fluid 
will ftill run out of A into D ; provided the 
repulfion of B on the fluid in the canal is not 
too great. 
The repulfion of B on the fluid in the canal, will 
at firfl: drive fome fluid out of the leg MP pm into 
A, and out of NP/>« into D, till the quantity of 
fluid in that part of the canal which is nearefl to B is 
fo much diminifhed, and its repulfion on the reft of 
the fluid in the canal is fo much diminifhed alfo as 
to compenfate the repulfion of B : but as the leg 
is longer than the other, the repulfion of B 
on the fluid in it will be greater confequently fome 
fluid will run out of A into D, on the fame principle 
that water is drawn out of a veflel through a fyphon : 
but if the repulfion of B on the fluid in the canal is fo 
great, as to drive all the fluid out of the fpacc GPH
