let a due Regard be had to the Moon's Eccentricity. Nay, I appeal to Multitudes of [[underline]] Observations [[/underlined]] of [[underline]] Mars [[/underline]], made or to be made when he was or will be nearly in Opposition to the Sun, in several different Ages of the Moon. For the Sun's Parallaxes derived in like Manner from [[underline]] them [[/underline]], especially about the Two Quadratures of [[underline]] Mars [[/underline]] with the Moon, will be found widely different from one another. If the Situation of the Point G be neglected; And if it be taken, for instance, from Sir [[underline]] Isaac Newton [[/underline]].
6. And if they shall find, or if any Astronomers or myself shall find (when we know the Days and Hours when these aforesaid Observations were made) That so very great a Parallax of [[underline]] Mars [[/underline]] ([[underline]] viz [[/underline]]. of 375" or 6'15") is consistent with the said Observations; What must be then concluded, but, [[underline]] that my Theory [[/underline]] (demonstrated, confirmed, and tried, already, by so many different Ways, and which will be further tried and confirmed, by thise unexpected and critical Trial, or by Multitudes of former or future Observations of [[underline]] Mars [[/underline]] or of [[underline]] Venus, [[/underline]] and by many other Ways more) [[underline]] can not be false; but necessarily be true.

7. As to the [[underline]] common Center of Gravity [[/underline]] of the Earth and of the Moon (beside what we can do barely by Demonstration and reasoning upon some Astronomical [[underline]] Data [[/underline]]) we may find also by [[strikethrough]] some [[/strikethrough]] immediate Observations, in what Proportion [[underline]] it [[/underline]] divides the Line that joins the Centers of these two Globes or Spheroid[[insertion]] ^ e [[/insertion]]s. And this does only require, for instance, some most accurate Observations of the Meridian Altitudes of the Sun, in and about the Times of the Solstice: And that a just Regard be had to the Situation of the Moon
