For upon it, under God's Providence, may depend in some measure the Prosperity and Quickness of their Navigation; the Fortune of their Merchants; and the Lives of their Mariners, and of the Sea-faring People who are exposed to the same Dangers with them.
19. Many of the numerous Equations, which Sir [[underlined]] Isaac Newton [[/underlined]] brought into the Theory of the Moon, will be greatly affected, by the Difference of the Elements or Foundations which he built upon, from those truer ones which result from our Demonstrations. And some of those [[underlined]] Equations [[/underlined]] (by whose means he comes often to a true Conclusion, notwithstanding his fundamental Mistakes) would necessarily lead us into Errors, if they were admitted indifferently into our truer Theory. But before I consider these Things further, I intend, if God please, to publish, and that perhaps in my next Discourse, another fundamental Theorem, of the greatest Consequence for perfecting the Moon's Theory: And whose Use, in reference to all passed or future Observations of the Moon, is really inestimable; as all sincere Astronomers will readily confess.
