tia. The nature of this was still farther proved by reconverting 
it into a chlorid, which dissolved readily in strong alcohol, and 
gave a solution which burned with a carmine red flame. 
St. Léon Spring.—This mineral spring is situated in the val- 
ley of the Riviere ala Glaise, about a mile from the church of 
the Parish of St. Léon. It rises through the clays of the region 
which there rest upon the Trenton limestone. The water of 
the spring is clear and strongly saline, and is kept in constant ebul- 
lition by the escape of large quantities of carburetted hydrogen 
gas; the discharge from the spring is very considerable ; the 
temperature of the well was found to be 46° F. on the 12th 
October, the air being 42°. The specific gravity of the water at 
60° is 1011-23; its taste is at the same time decidedly saline and 
ferruginous, and a qualitative analysis showed the presence of 
chlorids, bromids and iodids of sodium, potassium, calcium and 
magnesium ; minute quantities of barium and strontium were 
likewise detected, and carbonates of lime and magnesia as usual, 
with small portions of alumina, carbonate of iron, and silica.
