    ce] | phere to each other, and the elective attraction which unites the bafe of oxygen gas with caloric ; in confequence of thefe, when the calcination ends, there is ftill a portion of oxygen gas united to the azotic gas, which the mercury cannot feparate.. But from repeated and varied experiments, which it would be tedious and ulelefs to relate, M. La- voifier concludes, that the common proportions of the atmofphere in our climate are 27 parts of ORY gen gas, and 73 azotic gas. We have thus related the experiments by which | the atmofphere is demonftrated to’be a compound fluid confifting of oxygen and azotic gaffes ; andit will now be neceflary to proceed to fhew that thefe gafles themfelves are other compound bodies, viz. that they are compounded of oxygen and azote, with a fufficient quantity of heat to hold them in the gafeous.form. — | The following experiment proves the above :— A glafs jar full of pure oxygen gas being inverted | over mercury, a fine piece of iron wire heated red hot at its extremity plunged into’ it burns with an aftonifhing brilliancy, giving out large fparks fimi- lar to.thofe in Chinefe fire-works, and falling to the . bottom in round globules. At the beginning of the combuftion there is a flight augmentation in the volume of air in the jar, caufed by the dilata- tion of heat; but prefently after a rapid diminu- a ae tion
