In his Definition of a Fluid, he feems to imply, that he thought Fluids to be compofed of primary Solids •, and, in the Beginning of his Principia, he fpeaks of Sand and Powders as of imperfed: Fluids. Bor ELL I has demonftrated, that the confti- tuent Parts of Fluids are not fluid, but confiftent Bodies; and that the Elements of all Bodies are perfedly firm and hard. The Incompreffibility of Water, proved by the Florentine Experiment, is a fufficient Evidence allb, that each primary Particle or Spherule thereof is a perfed and im¬ penetrable Solid. Mr. Locke too, in his EU'ay on Human V^ide’rjianding^ admits this to be fo. This famous Experiment was firft attempted by the great Lord Verulam, who inclofed a C^antity of Water in Lead, and found that it inclin’d rather to make its way through the Pores of the Metal, thaji be reduced into iefs Com- pafs by any Force that could be applied. The Academicks of Florence made this Experiment after-
