at the Distance LT (or at any other Distance) will be somewhat increased by the Effect of that Refraction. But that Increase, which is very small in the Earth's Atmosphere, will be still much smaller in the Atmosphere of the Moon; so as not to be perceived by us, but with the help of very good Telescopes. Let the right Lines TZA and SZN touch the increased Globe of the Moon; and let SA be perpendicular to TA. And so the Angle STA will be equal to the Semidiameter of the Moon apparent to the Point T. And let SR be perpendicular to the refracted Ray of Light TbR.  Let the right Line Ts touch the Surface of the Sun in S:  And so the Angle STs will be equal to the Sun's apparent Semidiameter at the Distance TS from his Center. And the Angle RZA will be equal to twice the horizontal Refraction of Light in the Moon's Atmosphere. Let the Semidiameter Tf of the Globe of the Earth be perpendicular to the Plane ST. And thro' the Intersection Z, of the Tangents drawn from S and T, so the increased Globe of the Moon, draw the Line DZPF equal and parallel to TF: And let it cut ST in D. Likewise let SX Tangent of the increased Globe of the Earth cut DF in P and FF in X. Lastly thro' the Point X draw the Line XNI parallel and equal to FT; and let it cut the Lines SZ and ST in N and I. And transfer the Projection of the Solar Eclipse from DP to IX; that so the Projections of the Earth, for Eclipses of fixed Stars and for Solar Eclipses, may have y^e same Semidiameter TF.
