...demonstrated in the doctrine of projectiles. It is found by experiment, that when a ray passes out of air into water, the sine of the angle of incidence is to the sine of the angle of refraction, as 4 to 3; and when out of air into glass, as 3 to 2, or rather as 17 to 11, more nearly.

This amounts to the same with saying, that, in the case before us, the sine of the angle of incidence is to the sine of the angle of refraction in a given ratio.
