Proportion of the diminifh’d Diftance from the Center 
of the Force, and fo vice versa j but he has follow’d 
Sir Ifaac Newton no farther than ferv’d his prefentPur- 
pofe; other wife hewou’d have known. — Thatinrefped 
to a Central Body (as a Planet) towards which others 
are (attracted or) impell’d by Gravity, this Law ob- 
tains only, as Bodies attraded, are remov’d from the Sur- 
face of the Planet, to greater Diftancesfrom the Center 
compar’d with that Diftance ; or as from greater Di- 
ftances they approach nearer to the Planet. —.That the 
greateft Adion of Gravity is at the Surface of the Pla- 
net. — That afterwards in advancing towards the Center, 
the Force of Gravity, on the Body attraded, continually 
grows lefs, decreafing diredly as the Diftance ; and that 
this holds true in a Spheroid as well as a Sphere. — That 
on different Parts of the Surface of the Earth (in the 
Condition it is now) the Gravity on Bodies is recipro- 
cally as their Diftance from the Center of the Earth. 
That though at a confiderable Diftance we look upon 
the Earth, or any Planet, or even the Sun, as a Point 
(in the Center of the Forces tending towards it) endued 
with an abfolute Force, proportional to its Quantity of 
Matter ; yet when we come fo near the Body as to 
confider the Space it takes up, we are to take notice, 
that the whole Attradion or Gravity of the Body, is 
made up of the Sum of the Attradion of all its Parts pro- 
perly combin’d , and therefore, that when a Corpufcle, 
or Body attraded, comes to be within the Planet, or 
Body attrading, the Matter above it draws it back in 
fuch a Manner, that it leaves it only a Force to go on to- 
wards the Center, which is diredly as the Diftance as 
we have already Laid j juft as if a Body concentric to the 
Planet (whether fpherical or fpheroidical) had its Sur- 
face juft where the Corpufcle is, and all the exterior 
Cruft or Shell was annihilated.
