    C AII n 0 NIC ACID G A S, OK FIXED AIR. Chemists at an early period liad noticed the two-fold P:ate in which alkaline falts are found, and accordingly had termed them fixed or cavfilic ; but it is only known fince the experiments of Doctor Black of Edinburgh, that the different ftates in which thefe fubllances appear depend upon the prefence or abfence of tire balls of that Gas which he denominated fixed air. Modern Ohetnifts have made further difeoveries upon this fubject, and have proved that fixed air is a true acid of a peculiar kind, which becaufe it was found in the atmofphere received the name of aerial acid, but fince it has been dif- covered that it confifisof Oxygen and Carbon*, it has been termed Carbonic Acid Gas—the pro~ portion of its conftituent parts are twenty-eight parts of Oxygen and leventy-two parts of Carbon in the hundred. See Fourcrofs Cbemi/iry, vol, 3. This * The Word Carbon is adopted from the nomenclature of the French Chemifts to exprefs aninflammable matter which couiiitutes the chief part of the weight of Charcoal,
