    46. IBy latent heat (an cxpreffion certainly im- proper) is underftood heat not fenfible to our or- gans; that which, flridlly fpeaking, is not heat: it is combined caloric (44) which occafions no heat. This combined fluid is ready to make us feel heat; but for that purpofe, it mufl firft become free (43). 47. It is not improbable that the great elalficity of aeriform fluids arifes from that of the caloric united to them, and which appears to be a body highly elaftic by’ its nature. This, indeed, is ex- plaining elaflicity by elaflicity, and removing a dif- ficulty without relolving it; but fmce our know- ledge extends no farther, we mufl: admit this con- jecture till fomething more fatisfaCtory can be ob- tained. Formation and Conjiitution of the Atmof^here , of the Earth. 48. What has been here faid, will lerve to give fome idea of the manner in which our atmofphere has been formed. It may readily be conceived, that it mufl: be the refuk and mixture, ifl:. Of all thofe fubilances fufceptible of remaining in an aeriform flate at the ufual degree of heat and preflure which we experience; 2d, Of all thofe fluid or concrete fubilances fufceptible of being diifolved in that af- feinblage of different gafes. 49.
