    9 / EXPERIMENTS AND OBSERVATIONS RELATING TO THE ANALYSIS OF ATMOSPHERICAL AIR. It is an elfential part of the antiphlogiftic theory, that in all the cafes of what I have called the fihlogiftication of air, there is fimply an abforption of the dephlogifticated air, or, as the advocates of that theory term it, the oxygen contained in it, leaving the phlogillicated part, which they call azote, as it originally exifted in the atmofphere. Alfo, according to the princi¬ ples of this fyftem, azote is a fimple fubftance, at lead; not hitherto analyzed into any other j They therefore fuppofe that there is a determi¬ nate proportion between the quantities of oxygen and azote in every portion of atmofpherical air, and that ail that has hitherto been done has been to feparate them from one another. This proportion they date to be twenty-feven parts of A Q oxygen
