CHAPTER X. 
THE CHLORID GROUP. 
Waters of this class are generally called ‘‘brines,’’ although 
many of them do not contain a sufficient quantity of sodium 
chlorid to be workable for salt, or they contain too many for- 
eign ingredients to be of use. 
The chlorid waters are obtained from the solution of the salts 
that have been left after the drying up of some ancient ocean. 
It is said that they show their relation to the ancient seas rather 
than the modern, because they contain calcium chlorid or sul- 
fate, as well as chlorids of the alkalies and magnesium chlorid, 
salts which are present in modern sea water. Waters of this 
class are frequently called ‘‘saline,’’ from the abundance of 
common salt which they contain, although some have objected 
to this term as a misnomer, since all mineral waters contain 
‘‘salts’’ in the ordinary chemical acceptation of the term. 
Since the ocean is the great storehouse of bromids and iodids, 
we find that these waters often contain both these ingredi- 
ents. We look here also for waters rich in magnesium. Waters 
of the chlorid group have found their most important use for 
bathing purposes, although, diluted with soft water, they may 
be used internally. Some waters that are classified here as 
brines are already diluted in nature, and as such may be used 
internally. 
This group is represented by the following waters : 
Abilene, Dickinson county, artesian well. 
Arkansas City, Cowley county. 
Atchison, A. B. C. laundry well. 
Atchison, Becker’s well. 
Atchison, diamond drill prospect well. 
Kureka, Greenwood county.
