Mr, Cavenpisn’s Experiments on Air, 169 
That phlogifticated air fhould confift of fuperfaturated nitrous 
air, I think improbable, as it retains its phlogifton much more 
ftrongly than nitrous air, which, according to the general laws 
of affinities, it fhould not, if it contained an excefs of phlogif- 
ton; and as Dr. PriestLey and Mr. Fontana repeatedly af- 
fure us, they have converted it into common air, by wafhing it 
in water, in contact withthe atmofphere. Iam, Sc.
