of the Moon.  And by consequence, In any Cases where the Proportion of cT to cp or CP is known, whether in Feet or in Parts of the Radius CP or cp; There will also be known the Parallax of the Sun in reference to the Sphere olp:  And we have it ready calculated at hand, in the Tab[[insertion]] ( = les [[/insertion]] of Natural Sines; as may be seen in the following Table.

  18.  And indeed, if upon SC or ∫o we erect the Perpendicular TQ or Tq cutting the Sphere OLP or olp in Q or q; and if from Q or q we erect a Perpendicular upon SQ or ∫q; That Perpendicular will pass thro' the Center C or c:  And SQ, or ∫q will be a Tangent of the Sphere OQLP or oqlp.  For, in the Circle whose Diameter is CS or c∫, The tangent SQ or ∫q; Is to QT, or to qT, perpendicular to SC or to ∫c:  As the Radius; To the Sine of the Parallax QST or q∫T.  And by consequence CQ, or CP; is to CT; and cq, to cT:  As the Radius; To the Sine of the Parallax QST, or ∫qT:

   19.  And if we take for Radius CP, or y [[superscript]] e [[/superscript]] Semidiameter of the Orbit of the Moon; Then y [[superscript]] e [[/superscript]] two smallest possible Excentricities E and e, expressed in Parts of that Radius, being sought for in the Table of Natural Sines, will give there the Natural Sines of the Parallax[[insertion]] ^e [[/insertion]]s of the Sun, in reference to the aforesaid Spheres OLP or olp.  Thus CT the smallest possible Excentricity equal to 4332,267 2/3 (derived from Sir [[underline]] I. Newton [[/underline]], p. 462) gives in the Table that Parallax of the Sun of 2° 28' 284.5/2906.  Which Excentricity he and Mr. P. [[underline]] Wright [[/underline]] ought to have given in two very different Numbers, [[underline]] viz. [[/underline]] for Summer and Winter; if their Numbers were as they should be:  Since from them ought to result the Summer Parallax and the Winter Parallax; whose Proportion is nearly as 983 1/12 to 1016 11/12.
