[[underlined]] Some fundamental Inconsistencies demonstrated in the commonly received Planetary System, in order to make Way for determining truly the Sun's Distance or Parallax. [[/underlined]]

[[underlined]] Here the Proportion of the Gravitation in the Surfaces of the Earth and of the Sun is determined. [[/underlined]]

  1. SIR [[underlined]] Isaac Newton [[/underlined]], p. 405, supposing 10' 33" to be the greatest heliocentric Elongation of the Moon from the Center of the Earth (and this probably when the Sun and the Moon are at their mean Distances from the Earth) concludes, by Mistake, That the Gravitations of the same Body, in the Surfaces of the Sun and of the Earth, would be as 10000 to 435; or as 22,9885 to 1.
  2. It would have been easy for that Great Man to verify, by his own Conclusions and Determinations, whether the Parallax of the Sun could be so exceedingly little as he does there suppose it to be. For he might have found the Gravitation of Bodies near the Surface of the Sun as follows, independently from the Parallax or Distance of the Sun. But he was wholly prepossessed by the current Opinion of our best Astronomers, who have ever supposed the Distance of the Sun much too great.
  3. He determines the mean apparent Semidiameter of the Sun to be of 16' 6"; whereof the Sine is 7.6705504. Which Sine, in Logarithms, is to the Radius, as the Unit to 2.3294496, or to 213,5254. And this is the mean Distance ST betwixt the Centers of the Sun and of the [[strikethrough]] Moon [[/strikethrough]] Earth, expressed in Semidiameters of the Sun; which therefore amount to about 231 1/2 Solar Semidiamters.

Transcription Notes:
Ambrosia:- Think 22,9885 is correct as I think Mary writes 8 like that. Meg could you check this? Page 471 also show this symbol. We should be consistent in our guess.
