but amended by plac [[strikethrough]] e [[/strikethrough]] ing the Center of the Moon at its true Distance from the Center of the Earth: And let another Circle represent the Moon for the same Moment, with her proper Diameter apparent to the Point T, and deduced either from most accurate Observations made during the total Obscuration; or else from Eclipses of fixed Stars, or from an accurate Theory: And I say, That the Angle FXP, or y [[superscript]] e [[/superscript]] [[underlined]] Difference [[/underlined]] between y [[superscript]] e [[/superscript]] 2 Semidiameters of y [[superscript]] e [/superscript]] Projections, DP and IX, [[underlined]] expressed [[/underlined]] in Minutes and Seconds, will give the Sun's Parallax in reference to the increased Globe of the Earth: While the Angle AZR gives the double of the horizontal Refraction of the Rays of Light in the Moon's Atmosphere.
10. And here we must take particular Notice, that TF being chosen at discretion, in whatsoever Plane FD perpendicular to ST we make a Projection of the increased Globes of the Earth and of the Moon as seen from a fixed Star; the Projection will always remain exactly the same, and have the same Diameters both of the Earth and of the Moon, and all the same Lineaments; becuase of the vast Distance of those Stars from us.  And this will hold true, whether the Distance TD be never so small, as suppose equal to TI: Or whether it be, for instance, of 65, or 1000 Semidiameters of the Earth.
11. But in reference to a Projection drawn upon the Plane DF for a Solar Eclipse, the Case is not so.  For then the Eye is supposed in the Center of the Sun S: And the Tangent SPX determines the Semidiameter of the Projection of the Earth as seen from S to be equal to DP; while the Semidiameter DZ of the Projection of the Moon upon the Plane DF or DP remains sensibly equal to
