    effervesces, and a considerable quantity of the gas is liberated. The alcoholic solution has a peculiar taste, and is neutral to test papers. Olive oil dissolves about six volumes of the gas. Solution of alkali does not affect it; nor does muriatic acid. Sulphuric acid condenses the gas in very large quantity; 1 volume of the acid condensing above 100 volumes of the vapour. Sometimes the condensation is perfect, at other times a small quantity of residual gas is left, which burns with a pale blue flame, and seems to be a product of too rapid action. Great heat is produced during the action ; no sulphurous acid is formed ; the acid is much blackened, has a peculiar odour, and upon dilution generally becomes turbid, but no gas is evolved. A permanent compound of the acid with carbon and hydrogen is produced, and enters as before mentioned into combination with bases. A mixture of 2 volumes of this vapour with 14 volumes of pure oxygen was made, and a portion detonated in an eudio- meter tube. 8.8 volumes of the mixture diminished by the spark to 5.7 volumes, and these by solution of potash to 1.4 volumes, which were oxygen. Hence 7.4 volumes had been consumed, consisting of Vapour of substance 1.1 Oxygen - 6.3 Carbonic acid formed 4.3 Oxygen in carbonic acid 4-3 Oxygen combining with hydrogen 2.0 Diminution by spark 3.1 This is nearly as if 1 volume of the vapour or gas had required 6 volumes of oxygen, had consumed 4 of them in
