 [ 6 ] Refraction be created out of Air into Water, the sin of Incidence of the red light-weight is to the sin of its Refraction as four to three.  If out of Air into Glafs, the Sines square measure as I7 to II. In light-weight of alternative colors the Sines produce other Proportions: however the distinction is FO very little that it want feldom be confidered. Suppofe so, that R S [ in Fig. I. ] repre-fents the Surface of ftagnating Water, which C within the purpose of Incidenec within which any Ray coming back within the Air from A within the Line A C is mirrored or refracted, and that i would understand whither this Ray fhall follow Reflexion: I erectupon the Surface of the Water from the purpose of Incidence the Perpendicular C P and turn out it downwardly to letter, and conclude by the firft Axiom, that the Ray when Reflexion and Re-fraction, Fhall be Found fomewhere within the Plane of the Angle of Incidence A C P made. I Let fall so upon the Perpendicular C P the sin of...

Let that Ray in going out of the Glaſs be incident upon N, and so notice the ſecond refracted Ray weight unit by the Proporti- on of the Sines eleven to seventeen. And when the ſame manner might the Refraction be found once the Lens is gibbous on one ſide and Plane or Con- cave on the opposite, or bowl-shaped on each each. A X. VI.
