A Comparison of Some of the Most Important Constituents of the 
Sulfid Group. 
The comparison of these waters shows that there is very little 
analogy between them. ‘They are simply waters of various 
classes that contain hydrogen-sulfid gas, hydrosulfids, sulfids, 
or hyposulfites. The amount of mineral matter varies between 
wide limits, as the analyses quoted show; that of Aix-les-Bains 
contains only twenty-five grains per gallon, while the Harrow- 
gate water contains 864 grains. Chlorids are usually found, 
and sulfates are not wanting in any of the waters discussed. 
Indeed, sulfates would always be iooked for in these waters, as 
the sulfate ion is produced by the oxidation of the sulfur ion. 
The only exception to this would be in waters that contained 
barium and strontium, as does the Geyser well at Rosedale ; 
here the sulfid may have oxidized and precipitated a part of the 
barium and strontium as sulfates. Magnesium and calcium are 
also generally present, but the carbonate ion is not usually 
abundant.
