Brandon^ Manitoba. — A partial analysis was made in the laboratory 

 of the Survey — Geol. Surv. Rep. 1882-84, p. 18 MM. — of a water from 

 a shallow well north of Brandon : 



Potassa and soda a large quantity ; ?oda predominating 



Lime a " 



Magnesia . . a " 



Sulphuric acid a very large quantity 



Carbonic acid a rather large quantity 



Chlorine a " small " 



Sulphuretted hydrogen 



After being filtered it was found to have a content of solids — -dried 



at 100° C = equivalent to 268"9 grains to the imp. gall. The water at 



the time of the examination smelt strongly of sulphuretted hydrogen 



and had a most offensive odour. 



Clearwater River., N. W. T. — In the same volume an analysis is 



given of a specimen collected by Dr. Robert Bell and labelled as 



follows : — " Salt resulting from the evaporation of about five and a half 



quarts of water of a spring situated on the north bank of the Clearwater 



River, about four miles below the Cascade Rapid, N. W. T. From \ 



to \ more adhered to the kettle and was lost." The residue handed in 



for examination weighed 595 grains. 



Potassa very small quantity Ferric oxide very small quantity 



Soda " large '" Sulphuric acid " large " 



Lime , " " " Chlorine " 



Magnesia " " Carbonic acid " " " 



Alumina " small " Insoluble residue ..." " " 



Rosenfeld Station, Manitoba. — The water was obtained from an 

 artesian boring made at Rosenfeld Station, C P. R., at a depth of 235 

 feet, from which depth and lower points the water rises and flows in 

 considerable quantities, Mr. G. C Hoffmann, Geol. Surv. Rep. I, 1885. 

 p. 13M — says: — The filtered water was perfectly colorless ; taste, 

 strongly saline with a very slight bitter after taste ; it did not affect the 

 color of turmeric paper, but exhibited a slightly alkaline reaction with 

 reddened litmus paper. The reaction for boric acid, although faint, 

 was quite distinct. Bromine and iodine are both present — the amount 

 of the former exceeding, apparently, that of the latter, — but owing to 

 a total insufificiency of material, the determination of the respective 

 amounts of these constituents, could not be carried out. The specific 

 gravity of the water, at i5"5° C, was found to be 1032-86."
