Excess cations 0-036159 



The excess of cations, 0-036159, equals C0 3 ions expressed 

 as monivalent ions or 0*018079 bivalent ions corresponding to 

 1*084:74 grams C0 3 equal to 0-794438 gram C0 2 combined as 

 neutral carbonates. 



Total C0 2 found was 2-5660 



C0 2 combined as neutral carbonates 0*7944 



1*7716 

 C0 2 combined as bicarbonates 0-7944 



C0 2 wholly free per liter 0-9772 



The C0 2 wholly free corresponds to 496*84 cc per liter at 

 0° C. and 760 mm pressure. 



Hydrogen sulphide considered as wholly free equals 0*0492 

 gram or 32*12 cc per liter. Specific gravity at 16° 1*00400. 

 Total solids 3*6825 grams per liter. 



The Drinking Spring. 



The water of this spring is by far the most interesting one 

 of all the group : it is clear and limpid with a decided odor of 

 hydrogen sulphide. The discharge of gas is moderate but 

 constant. There are smaller springs of the same character in 

 its immediate vicinity. The spring is nearly circular with a 

 diameter of 12 to 14 inches.
