AMERICAN MINERAL WATERS. 



Saline waters are those which have an alkaline or neutral reaction 

 and contain sulphuric, muriatic, or nitric acid ions in predominating 

 quantities. 



Alkaline-saline waters are those with both alkaline and saline 

 characteristics. They embrace those which have an alkaline reaction 

 and contain (1) sulphuric, hydrochloric, or nitric acid ions, together 

 with carbonic or bicarbonic acid ions, both classes being present as 

 predominating constituents, or (2) those which have an alkaline 

 reaction and contain sulphuric, hydrochloric, or nitric acid ions with 

 boric or silicic acid ions, both classes being present as predominating 

 constituents, where it can be demonstrated that the alkalinity is 

 largely due to the presence of borates or silicates. 



Acid waters are those which have an acid reaction and contain 

 either sulphuric or muriatic acid ions in predominating quantities. 



METHOD OF NAMING MINERAL WATERS. 



If any basic element is prominent in the mineral water this fact 

 may be indicated by prefixing the base to the regular class name, 

 as sodic, lithic, calcic, etc.; carbonated alkaline, borated alkaline, 

 silicated alkaline, sulphated alkaline-saline, etc. 



If any basic or acid ion is prominent therapeutically but not 

 chemically, this fact may be indicated by affixing the name of the 

 basic or acid ion to the regular name, as carbonated alkaline (arsenic, 

 bromic, iodic, etc.). 



The gaseous constituents of all the foregoing classes of waters may 

 be designated by the following terms : 



Nongaseous Containing no gas. 



Carbondioxiated l Containing carbon dioxid gas. 



Sulphureted Containing hydrogen sulphid gas. 



Azotized Containing nitrogen gas. 



Carbureted Containing methane gas. 



Oxygenated Containing oxygen gas. 



The following scheme enables one to name any mineral water 

 according to Hay wood's classification: 



1 This word is introduced so as to distinguish between free carbon dioxid and carbon dioxid in 

 combination.
