It is so abundant in many springs as to escape in bubbles from the surface of the water, as those of Saratoga, in the State of New York, of Baden Baden and Carlsbad, in Germany, and of Pyrmont, in England. Carbonic acid is heavier than the atmosphere in the pro- portion of forty-seven of the former to thirty-one of the latter, and, like chlorine, may be gathered by displacement of air from the vessel. It sometimes accumulates in old wells, which are not used, and in deep caverns, where the air is seldom agitated, where it has long been known as Choke Damp, from its fatal effects when incautiously Fiff. 13. This gas may be conveniently prepared by pouring some diluted CHLOROHYDRic ACID upon CHALK, or any of the carbonates, by which process the carbonic acid is sep- arated. Where does carbonic field exist free in nature ? In what proportion is it heavier than the atmosphere? Where does it sometimes accumulate? How can it be prepared?.
