    ._ To thefe bafes.of the different gaffes, which are hitherto but little-known, we have been ob- liged to affign names :,Thefe {hall be enumera- ted in Chap. IV..of this work, when I have pre- vioufly given an account of the phenomena at- tendant upon the heating and cooling of bodies, and when Ff have.eftablifhed precife ideas, con- cerning the,compofition of our atmofphere. . We have already fhewn, that the particles of every fubftance in nature exift in a certain ftate of equilibrium, between that attraction which tends to unite and keep, the particles together, and the effeéts of the,caloric which,'tends to feparate'.them.; Hence; caloric not; only fur- rounds-the particles of all bodies on every fide, but fills up every interval which. the :particles of bodies leave between each other. We may form an idea of this, by fuppofing a veffel fill- ed with. {mall fpherical leaden. bullets, among which a quantity, of fine fand is. poured ; this, infinuating itfelf into the intervals between the bullets, will fill up» every void... The balls, in this comparifon, are to the fand which furrounds them exactly in the fame fituation .as the pars ticles of bodies are with refpect to. the-caloric ; with this difference only, that the balls are fup- poted to touch eachother, whereas the particles of bodies are not in contact, being retained at a {mall ditance from each other by the calo; RiCs I iwi 3 } iid vig ]|
