   20. Likewise the Second Excentricity TF or Tf, ([[underline]] vis. [[/underline]] the Distance between the Center of the Earth and the Focus F, or f, of the Orbit of the Moon, which Second Excentricity is also double, for Summer & Winter) That Excentricity TF or Tf, variable throughout the Year, depends wholly upon the Density of the Sun, which must needs be proportional to the Fall HI or HK, while the Distance ST and the Bigness of the Sun are supposed to remain unchangeable, and the Triangle TLS to be rectangular: Or else must be proportional to the Fall [[underline]] hi [[/underline]] or [[underline]] hk [[/underline]], if the Triangle TSL be supposed equicrural. 
     21. That Fall HI or HK, or else [[underline]] hi [[/underline]] or [[underline]] hk [[/underline]], is [[strikethrough]] is [[/strikethrough]] ever proportional to 1/ST², and has, by consequence, its Exponent proportional also to the natural Sine of the Sun's Parallax, both in reference to the Sphere OLP or [[underline]] olp [[/underline]], and in reference to the Globe of the Earth; while the opposite Excentricity E, or e, continues to be one of the two smallest possible Excentricities; or while the Equicrural Triangle LST, or the Rectangular Triangle SLT remains the same or unchangeable. But the Density of the Sun and the Radius of y [[superscript]] e [[/superscript]] Great Orb do change, in the same P[[insertion]] ^ r [[/insertion]]oportion [[strikethrough]] of [[/strikethrough]] as HI or HK or else [[underline]] hi [[/underline]] or [[underline]] hk [[/underline]] is supposed to change.
     22. And contrariwise, If the Parallax of the Sun, in reference to the aforesaid Sphere OLP; be of Two Degrees and 17', or 2° 21', or 2° 25', &c; Then the smallest possible Excentricity CT must be, by the Table of Natural Sines, of 3984,11, or 4100,37 Parts, &c. as in this short Table.
