represents, in the same Projection, the Semidiameter of the Moon apparent to the same Point T.
 14. But, let the Reader take notice that, in the Figure, the perpendicular Lines as ST are represented vastly too short in reference to the horizontal Lines as FD.  And that the Line LT, which was in the [[underline]]total Eclipse[[/underline]] 1718 about 1/24 of ST, is also much longer in the Figure, than it should be in reference to ST.  And that likewise LT, which in the Figure is shorter than TF, was in reality about 65 times longer than TF.  The Things which were to be represented, and the Smallness of the Figure, did cause this Difformity; which however will in a manner disappear, if it be conceived that the Line TS being in reality about 1600 Times longer than TF in the Figure, is turned with the Sun about the Axis TF; till TS being seen from an infinite Distance by an Eye placed perpendicularly over the Point T, and so being projected in this Figure, it be reduced to the small Standard TS.
 15. It were to be wished that in the said [[underline]]Eclipses[[/underline]] or in the like total Eclipses, which appear so rarely, the apparent Diameter of the Moon had been observed with care, during the total Obscuration.  For that Observation would have been very curious in its Kind, and very instructive, chiefly in reference to the Refraction of Light in the Atmosphere of the Moon, and to the Distance at which she was then from us.  However this Defect may be pretty well supplied from the very [[underline]]Phonomena[[/underline]] of that Solar Eclipse, [[underline]]compared[[/underline]] with my Demonstrations and Theory about the Parallax of the Sun, and about the Dis-
