5. But as the aforesaid Fall of G, or as the Versed Sine 0, 455469; Is to its Radius 10.00, &c. So is pi supported even of 1 Foot; To 9.5445305 Feet; which being divided by 19615000 Feet; equal to the mean Semidiameter of the Earth, the Quotient would give G O or the Radius of the Great Orb equal to only 170,6 Semidiameters of ye Earth. But ye third Part thereof, or  60 Semidiameters of the Earth, seem to give more exactly ye Radius GO.

6. How amazing, how unexpected is all this, which wholly overturns the reigning and so much applauded System! But when we shall proceed to explain the true Frame and Disposition of the most magnificent Structure of the Solar System, we shall see the divine Wisdom to shine in it with a far brighter Lustre, than in the common System, clouded as yet with some intolerable Errors.

7. Sir Isaac Newton, and all our Astronomers and Mathematicians with him, agree that the Versed Sine, of the circular Arc which might be described in a short and given Time, by any Planet or Satellite, or by the common Center of Gravity G, in a concentric Orbit, is the true Measure of their Fall. To increase or diminish those Versed Sines beyond the Measure which Nature affords, draws after it some Difficulties, from which I could never extricate myself but by receiving the only true System, and forsaking that, which is inconsistent with itself.

8. In my next I intend, if God permit, to prove by Sir Isaac Newton's own Principles and irreprehensible Data, That the Gravitations in the Surface of the Sun and of the Earth, which he makes to be as 10000 to 435, are rather as 10000 to 100160. A prodigious and amazing Difference! which calls aloud for the Reader's singular attention.
