NOMENCLATUKE. 



11 



The gaseous constituents of all the foregoing classes of waters may 

 be designated by the following terms: 



Nongaseous Containing no gas. 



Carbondioxated Containing carbon dioxid gas. 



Sulphurated 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 accord- 

 ing to the authors' classification: 



A few examples may serve to render this system of nomenclature 

 more intelligible. Massanetta water (No. 689, p. 34) would be classed 

 as a nonthermal, calcic, bicarbonated, alkaline water; the Hot Borate 

 Springs of California (Crook's Mineral Waters of the United States, 

 p. 147) would b6 classed as a thermal, sodic and ammonic, borated and 

 bicarbonated, alkaline (iodic) water; Hathorn Saratoga water (No. 

 901, ^p. 45) as a nonthermal, sodic, muriated, alkaline-saline (lithic, 

 bromic, iodic) Carbondioxated water; Cherrydale water (No. 1013, p. 

 54) as a nonthermal, sodic, and calcic, nitrated and muriated saline 

 water; and Rockbridge alum water (No. 1223, p. 72) as a nonthermal, 

 aluminic, sulphated, acid (ferruginous) water. 



It is believed by the authors that if such a nomenclature as the 

 above were followed the general public would be able to obtain more 

 information from the name alone than from the inspection of an analy- 

 sis. It is apparent that much work would be saved for the physician, 

 who could soon reduce the waters to be considered in any given case 

 to a comparatively small number simply by the use of a well-arranged 

 index instead of being compelled to study hundreds of analyses. The , 

 group, class,' and subclass having been determined, it would be a com- 

 paratively easy matter to study the individual analyses. 



This word is introduced so as to distinguish between free carbon dioxid and car- 

 bon dioxid in combination.
