evolves a sufficient quantity of sulphuretted hydrogen, to give the 

 water a strong sulphurous taste and odour. No examination of the water 

 has been made, though it is said to be used to a considerable extent 

 locally. Many similar springs are known to occur m the vicinity, of 

 none of which, however, is anything definite known. 



MINERAL WATERS IN NOVA SCOTIA. 

 Bras nOr Lake, Victoria Co. — On the north shore of the Little 

 Narrows, Bras D'Or Lake, and about twelve miles south-west of Baddeck 

 are several brine springs, a specimen of the water of which was examined 

 by Mr. G. C Hoffmann (report Geol. Surv. 1873-4, p. 181). Although 

 more correctly a brine, it has been thought advisable to note its occurrence 

 here, the following analysis is by Mr. Hoffmann : 



Chloride sodium 50"688i Alumina traces 



" potassium "1942 Silica " 



" magnesium '1593 



Sulphate calcium 5'68io In 1,000 parts of water 567226 



Unsuccessful efforts were made to utilize this brine in the manu- 

 facture of salt ; works etc. having been erected and abandoned many 

 years prior to 1873. Mr, Chas. Robb, who collected the specimen 

 examined, states that in the neighborhood of the springs, of which there 

 are several, there is a noticeable odour of sulphuretted hydrogen. 



East Bay, Gape Breton Co. — At the junction of the Ben Eoin and 

 Gaspereaux River roads, and about four miles from the shores of East 

 Bay, is a spring which at one time had a comparatively wide reputation 

 and was resorted to by many in search of relief from rheumatic troubles. 

 The spring rises from syenitic rocks and the water has an unpleasant 

 brackish and astringent taste. An analysis afforded Prof. Hy. How, 

 Kings College, Windsor, the following result; 

 Chloride sodium 343'i i Phosphoric acid traces

Grande Anse, Richmond Co. — In the " Mineralogy of Nova Scotia 

 1868," page 194, Prof. Henry How, writes thus of a water found at 

 this place : — "' At Grande Anse, at the mouth of the McKenzie River, 

 two springs issue from the metamorphic Lower Carboniferous rocks
