    PART I. EXPERIMENTS, CAUTIONS, and CASES, tending to illuftrate the medicinal ufe of Factitious Airs, and of other fubflances, of which' the application to Medicine has been fuggefted by modern philofophical difco- veries. I,;—Of the Atmofphere. TT is proved, by fatisfa&ory experiments, that the inferior region of the atmofphere confifts of two kinds of air, quite^diftinct in many properties. One is the kind called Vital, Dephlogisticated, or Oxygen e Air, and by a variety of names befides. The other has been named Azotic, Phlogisticated, Foul, or Bad Air. Where the lower atmofphere is not altered by the breathing of animals, the burning of fuel, by.exhalations from fubterraneous chemical pro- ccfTes or putrefying fubflances, and fuch local caufes, if you confine and examine an hundred cubic inches, you will find twenty-feven or twenty-eight to be oxygene, and the remaining fcveniy-two or feventythrce azotic B # air.
