The amount of dissolved mineral matter present in some wells and
springs is surprisingly great; the famous springs of Bath, England,
contain so much mineral matter in solution, that a column 9 feet in
diameter and 140 feet high could be built out of the mineral matter
contained in the water consumed yearly by the townspeople.
