12. Here I cannot agree with Sir [[underlined]]Isaac Newton[[/underlined]]. For, not to mention at present what I cannot approve of in his Theory of Tides; he forgets here the Centrifugal Force, which the monthly Revolution of the Moon would produce in her fluid Body, for instance, her monthly Revolution about the second Focus in a Stereographic Orbit.

13. That Centrifugal Force is very great: And, in the parts furthermost from the second Focus, it is greater than in the next Parts to it, in the Proportion of the Distance of that Focus from these parts; which Proportion may very much exceed that of 214 to 216; the Centrifugal Force of her Center being rated at 215. Now the Centrifugal Force of her Center is so great, as to counterballance the Fall of her Body toward the main Focus.

14. The mean Semidiameter of the  Earth is to Sir [[underlined]]Isaac Newton[[/underlined]] of 19615000 [[underlined]]Paris[[/underlined]] Feet. And according to him, As 365, is to 100; so is that Semidiameter, to the Semidiameter of the Moon, supposing her to be Spherical. So the Moon's Semidiameter would be of 5374191 Feet. But I reckon it to be greater.

15. In a Stereographic Orbit, that great Mass of the Moon will naturally affect to have its long Axis turned towards the second Focus. For while [[underlined]]that Mass[[/underlined]] makes half a Revolu=
