MINERAL SPRINGS OF CANADA. In the communications of Mr. T. S. Hunt, who was engaged in the geological survey of Canada, we have interesting notices of some of the chief mineral springs of that country. The Tuscarora Acid Spring.--The same region in which occur the acid springs of New York offers in Canada a remarkable one of a similar kind. Mr. Hunt describes it with the above title. It is situated in the township of Tuscarora, in the Indian Reserve, about twenty miles north of Pass Dover, which is the nearest point on Lake Erie. The water contains a large amount Silliman's Journ. New Series, Vols. viii. & ix. of free sulphuric acid, about 4 parts in 1000, besides sulphates of the alkalies, lime, magnesia, alumina, and iron in small quantities. The proportion of these ingredients is, however, inconstant, as is evident from an analysis made in April, 1846, by Professor Croft, of King's College, Toronto, which is confirmed by a partial examination by Mr. Hunt of a specimen of water brought from the spring in 1845. The specific gravity of the water was much lower, and the amount of foreign ingredients much less, than in that subsequently collected by himself; but the proportion of bases to the acids was much greater. The principal spring is at the east side of the old stump and gnarled roots of a pinetree, and has a round basin about eight feet in diameter, and four to five feet deep: the bottom is soft mud. There is no visible outlet to the basin, which, at the time of...
