supposing as above the Angle TLS to be changed into a right Angle; and LT to remain of 100 parts as before.
  16.  Then if with Sir [[underlined]] Isaac Newton [[/underlined]] we suppose the sun as it were at an infinite Distance from the Earth; and if we suppose the Moon to move in a Circular and Concentric Orbit, we have now found a manifest Distance from, and a notable Amendment to that original Supposition of Sir [[underlined]] Isaac Newton [[/underlined]], by which he made ST Infinite, or the Parallax of the Sun as it were wholly insensible.  And from thence it follows, that there is included, in that, and perhaps in some other Supposition of Sir [[underlined]] Isaac Newton [[/underlined]], a great and manifest Error.
  17. Now this new Parallactic Angle LST must be further corrected, and diminished, by proper Calculations and Approximations.
  18. If we fit our Calculation for an equicrural Triangle LST; then, As TS thus corrected, and whose Logarithm is 2.8762828, is to 1/2 LT; So is the Radius, to y[[superscript]] e [[/superscript]] Sine of 1/2 LST, equal to 3˚ 48' 43" and the Parallactic Angle LST comes forth of 7˚ 37' 25", 6 in an equicrural Triangle.
  19. The 60th Part of this number, or rather the 64th Part, would give nearly y[[superscript]] e [[/superscript]] mean Parallax of the sun, in reference to the Globe of the Earth.  Which Parallax deduced from some Suppositions and [[underlined]] Data [[/underlined]] granted by Sir [[underlined]] Isaac Newton [[/underlined]] would be of about 7' 8",83.
  20. But among these [[underlined]] Data [[/underlined]] there is a considerable one which seems exceedingly dubious to me.  And that is the great Density which Sir Isaac Newton gives to the Solar Matter; by making it but 4 times rarer than the Mass of Matter which
