From whatever fource the errors arife, whether from the evolution of phlogi(Heated nitrous acid, or the decompofition of water, or the produdlion of nitrous gas, they all tend to increafe the proportion of the carbonic acid to the nitrogenc. I am unacquainted with any experiment from which accurate opinions concerning the differ- ent relative proportions of oxygene and nitrogenc in the nitric and nitrous acids could be deduced. Lavoifier’s calculation is founded on his funda- mental experiment, and on the combination of nitrous gas and oxygene. ' Dr. Prieftley’s experiment mentioned in fedlion 12, on the abforption of nitrous gas by nitrous acid, from which Kirwan*- deduces the compofition of the differently colored nitrous acidsf was made over water, by which, as is * ElTajr 00 j)hlogiftoo.-
