On the Mineral Springs of Canada. 179 
The amount of solid matters in 1000 parts is by calculation 
13-836835 ; the quantity of carbonic acid above that required to 
form neutral carbonates, is equal to 29:16 cubic inches in 100. 
Cazton Spring.—This spring is situated in the township of 
Caxton, on the Yamachiche River, about five leagues from the 
village of Yamachiche. ‘The river here flows between banks of 
clay, which are often sixty to eighty feet high, and exceedingly 
abrupt. ‘The underlying formations are not exposed in the vi- 
cinity, but the position is probably near the dividing line between 
the Trenton limestone and the Postdam sandstone. 'The spring 
rises in the narrow valley that lies at the foot of the hill, and near 
the river, but a few feet above its ordinary level. The water, 
which is remarkably transparent, rises with great force, accom- 
panied with volumes of carburetted hydrogen gas, which keep 
it constantly in violent ebullition. The discharge of water is 
very considerable, probably six or eight gallons per minute ; the 
temperature of the well was found on the 25th of October, to be 
49°, that of the air being 44°. The specific gravity of the water 
at 60° F’. is 1010°36 ; it is strongly saline to the taste, but from the 
smaller portion of earthy chlorids, less bitter than that of St. Léon, 
Which it much resembles. Like that, it contains in addition to 
these and the usual alkaline chlorids, portions of bromids and iodids 
and a litle carbonate of iron. No salts of barium or strontium 
were detected.
