ANALYSES OF WELL, SPRING, MINERAL AND ARTESIAN WATERS. 113 
Mineral Waters. 
Mineral waters are those in which an unusually large amount 
of salts are held in solution, their medicinal or therapeutic pro- 
perties depending largely on the composition of the waters and 
the amount of the constituents present. There are various classes 
of mineral waters, some of which constitute excellent table waters, 
others possess medicinal qualities and are largely used for various 
complaints. 
The following is a description of some of the waters in use in 
Great Britain, the Continent, America and elsewhere :— 
The Carbonated Waters, which consist largely of the so-called 
bicarbonates of soda, potash, lime and magnesia, are represented 
by the Apollinaris Water and Seltzer Waters (Germany) and the 
Rock Flat and Cooma Waters (N.S. Wales). 
The Chalybeate Waters which contain salts of iron in solution, 
and impart to the waters an inky taste, such as those of the Tun- 
bridge Well spring and the Cheltenham Waters (England), and 
the water described in this paper from Mittagong. 
The Sulphurous Waters, sulphuretted hydrogen gas being the 
predominant ingredient, giving the waters a nauseous taste and 
smell. These waters are represented in the Harrogate Waters 
(England), and the Moffat Waters (America), also in a spring at 
Wilcannia (N.S. Wales). 
Sulphated or Purgative Waters, their chief ingredients being 
the sulphates of magnesia (Epsom’s salt) and soda (Glauber’s salt), 
are represented by the springs at Epsom, Fredrickshall, Ofen, 
Hungary (Hunjadi Janos Water) and the waters obtained in 
various places in the Broken Hill District (N.S. Wales). 
The Bromated and Iodiated Waters, which are represented by 
the Saratoga, Champion, and Congress Waters (New York) and 
H—June 1, 1892.
