Maisonneuve, Hochela^a Co. {a) — An examination was made by 



Mr. G. C. Hoffmann in the laboratory of the Survey (report Geol. Surv 



Vol. IV. 1888-89. P^^^ f^-) of ^ water from a deep boring on the 



property of Messrs Viau et Freres at Maisonneuve, near Montreal. 



The boring attained a depth of 1.500 teet, in rocks of Cambro- 



silurian age from which the water emanated. Of the physical 



features of the specimen, Mr. Hoffmann writes as follows: — 



" The sample of water sent for examination had, when received, a 



faint yet decided odour of sulphuretted hydrogen ; it contained but a 



trifling amount of sediment ; colour of the clear water, when viewed 



in a column two feet in length, light yellow; taste, mildly saline; 



reaction, faintly alkaline." 



The analysis gave the following" result : —
