Diameters to the Diameters oF the like Circles made by
Air to be about seven to eight, and consequenelr the in-
tervals ot the Cilasses at like Circles, caused by thole
trro mediums Water and Rir, are as about threc toFour.
Perhaps it may be a general Rule, That it any other
medium more or lels dense than ater be compressed
betreen che Cilases, their interrals at the Rings caused
thereby will Bc to their interrals caused by interjacent
