Note.— The phosphoric acid present is omitted from this table, but appears in the detailed 

 account of these waters. 



" * Traces. 



None of them in their natural state gave 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 waters in question 

 belong to two distinct classes — the alkaline and acidulous.
