None of them in their natural alale ae any indication of the presence 
of either iodine or bromine, nor were any such indications observed for 
those waters which, for more rigorous testing, I evaporated to a small bulk. 
The waters I thus treated especially for these elements are Nos. 1-6 and 
10-14, and as they represent all the kinds of waters of this series, I think 
it may be safely concluded that these substances are either absent, or, if 
present, are in quantities so small that they will not exercise any appreciable 
effect upon any one using these waters. 
The metal lithium was found in waters Nos. 2, 7, and 9, but only in 
such small quantity as not to be readily detected, except spectroscopically. 
As this is a substance having active medical properties, even when 
administered in small quantities, if continuously, it is- often an important 
matter that its presence in any mineral water should be known to those who 
use it. 
A perusal of these analytical results will show that the ini in question 
belong to two distinct classes—the alkaline and acidulous,
