180 On the Mineral Springs of Canada. 
The Plantagenet Spring.—I have never visited this spring 
which is in the township of Plantagenet, not far from the south- — Aas 
ern bank of the Ottawa, and rises through clays. 
The following analysis was performed upon a quantity of water 
furnished me by the proprietor of the spring in February, 1849. 
‘The water at 60° F. has a specific gravity of 1009-39 ; its taste 
is strongly saline, and more bitter than that of the Caxton spring, 
just described. Analysis shews the presence of the alkaline and 
earthy chlorids, with portions of bromine and iodine, besides car- 
bonates of lime and magnesia, with traces of carbonate of iron. 
1000 grammes of it gave—

The similarity between the last three waters is very close both 
in the nature and quantity of the ingredients which they contain. 
It will be observed that that of St. Léon contains, like the sources 
of Varennes, baryta and strontia, but in much smaller portions; 
while that of Caxton is distinguished by the large amount of 
earthy carbonates which it contains. ~These three springs, with 
the intermittent of Caledonia, constitute a well defined class of 
saline waters, which are contrasted with the other sources of
