angular Spaces intercepted between the laft Surface of 
the inferibed Sphere and that of the Cylinder,- it is 
manifeft, that no Change will happen in the Velo- 
city and axifugal Force of the reft of the Points, 
which are not included in thefej for this Reafon, 
that the Points which fill the Two kinds of Ba- 
fons that mark the Excefs of the Cylinder above 
the inferibed Sphere, remain in the fame Order, Dif- 
pofition, and Diredlion, with regard to the inferior 
Points, which they were in at the time of their Mo- 
tion. And there is no other Difference to be per- 
ceived herein, except that at prefent it is the fame 
Point that conftantly correfponds to the fame Place ; 
and that before this Place was fucceflively occupied 
by Points intirely refembltng each other, and that 
which remains or is fuppofed conftantly to remain 
therein. 
Now whether this Place be conftantly occupied by 
one and the fame Point, or fucceflively by Points 
intirely alike and in the fame Order, is what ought 
not to produce any Variation in the EfFed which we 
are examining : And this appears to me at leaft as 
clear as Noon-day, 
Wherefore, fince thefe inferior Points had then 
but an axifugal Force, it follows that even now they 
have no other Tendency than to recede from the 
Centres of their Circulations, without having any 
Force relative to the Centre of the Vortex. 
This is all that pure Reafon didates to me on this 
Point of the Nature of the Vortex, whether fpherical 
or cylindrical : And 1 dare flatter myfelf, that who- 
foever will attentively examine my Reafonings, will 
find
