    And if from thofe 40 grains we take 13 for the folution of ammonia introduced, the re- mainder, 27, will be the quantity of folution of nitrous acid in water remaining in the globe, which added to 54, equals 81 grains, the whole quantity formed ; but if from this be taken 41 grains, the quantity of water, the remainder 40 grains, will be the quantity of nitrous acid gas abforbed in the folution. To find the abfolute quantity of nitrous acid formed, we muft find the fpecific gravity of that abforbed ; but as during, and after its abforption, 17 grains of air, equal to 53,2 cubic inches entered, it evidently filled .fuch a fpace. 53,2 cubic inches of it confe- quently weigh 40 grains, and 100 cubic inches 75,17 grains. Then ^']b cubic inches weigh ,56 grains, and this added to 40, makes 40,56 grains, equal to 57,0 cubic inches, the whole quantity of aeriform nitrous acid pro- duced. ^ But the quantity of nitrous gas entering into this, allowing for the nitrogene it contained, is
