TWENTY-SECOND ANNUAL MEETING. 27 



of the spring may be seen a white deposit of sulphur, and the odor of hydrogen 

 sulphide is quite perceptible. 



Upon analysis the water is shown to contain the following constituents, the re- 

 sults being estimated in grams per liter: 



Calcium oxide .8422 



Magnesium oxide .1308 



Sodium oxide .0505 



Potassium oxide .0048 



Ferric oxide .0010 



Silica 0162 



Sulphuric anhydride 1.2704 



Carbonic anhydride (calculated ) .1432 



Chlorine 0280 



Hydrogen sulphide 



The constituents are probably combined as follows, the results being expressed in 

 grains per U. S. gallon of 231 cubic inches: 



Potassium sulphate 0.490 



Sodium chloride 2.688 



Sodium sulphate 3.188 



Magnesium sulphate 22.884 



Calcium sulphate 97.391 



Calcium bicarbonate 24.867 



Iron bicarbonate 0.175 



Silica 0.945 



Sodium bicarbonate Trace 



Sodium hydrosulphate Trace 



Total solids 152.578 



Free carbonic acid gas. 

 Free hydrogen sulphide gas. 



PAESONS MINEEAL WELL. 



This water comes from a well about 30 feet in depth, situated upon a farm on 

 the open prairie. It is remarkable in the large amount of nitrates contained, and 

 the abundance of magnesium salts. 



Upon analysis, the water is shown to contain the following ingredients, estimated 

 in grams per liter: 



Calcium oxide .6914 



Magnesium oxide 1.3528 



Sodium oxide 4454 



Potassium oxide .0074 



Ferric oxide .0008 



Silica 0146 



Sulphuric anhydride 3.6742 



Chlorine 1414 



Nitric anhydride .0162
