Decompofition is always made in a perpendicular 
Line to the Point that caufed it. 
And indeed, either the Radius I C paiTes through 
the Centre of the Globule C, or the Centre of this 
Globule is on one Side or the other of this Radius-, 
but fo as that this Radius cuts the Point C y or elfe, 
it is a Space intercepted between Two Globules, 
which diredly anfwers to the Point C. In the Firft 
Cafe, there is no Decompofition : In the Second, and 
in the Hypothefis, that the Centre of the Globule C 
happens to be between the Radius IC and the 
Equator, there will be a Decompofition j but it is 
manifeft, that it will not be a central one ; It will, on 
the contrary, be relative either to the very Pole, or 
to one of the polar Circles. In the Third Cafe, 
wherein it is fuppofed, that it is a Space intercepted 
between Two Globules, which anfwers to the Point 
C ; there may be a Decompofition, but it will be 
double, the one relative to the Centre O, and the 
other relative to the Pole Z. 
Now the Cartejians can never draw from this 
Decompofition the Advantage they propofe becaufe 
there will not be more Reafon for heavy Bodies pre- 
cipitating to the Centre of the Sphere by means of 
the central Force, than to the very Pole by the 
Afliftance of the polifugal Force ^ or rather, the Com- 
plication of thefe Two Forces will compel the Mo- 
bile to precipitate to the Centre I of the Parallel it 
happens to be in. 
Wherefore, in order to defend the fpherical Vor- 
tex, they muft fay, that the Centre of the Globule 
C is comprehended between the Poles and the Ra- 
dius I C. But on what Foundation will they affure it ?
