Mineral Waters of Canada. 267 
have conformed to the general practice of chemists, rather be- 
cause the results are more intelligible to the unscientific, and at 
the same time more readily compared with those of other analysts, 
than because the compounds thus calculated can be supposed to 
represent the real constitution of the water; for in the present 
state of our knowledge, we must, I think, be led to adopt the 
idea of a partition of bases among the different radicals, so that 
the bromine in a saline water instead of being, as it is here repre- 
sented, in conformity with general custom, combined as a bromid 
of magnesium, is divided between the four metals usually present, 
in proportions which we have not yet the means of determining. 
_ The analyses were performed upon weighed portions of water 
m preference to using measures; and the weights, including the 
Specific gravities, were determined by a delicate balance made to 
order by Deleuil of Paris, and sensible to the demi-milligramme, 
when loaded with two hundred grammes. 
The Caledonia Springs.—T hese springs which are well known 
as a place of resort during the warm season, are situated a few 
miles south of the Ottawa River, about forty miles from Montreal ; 
the fountains which are four in number rise through strata of 
post-pliocene clay which overlie a rock equivalent to the Trenton 
limestone. Three of them, known as the Gas Spring, the Saline 
Spring, and the White Sulphur Spring, are situated within a dis- 
tance of four or five rods, and the mouths of the latter two are 
not more than four feet apart. The fourth, known as the Inter- 
mitting Spring, is situated about two miles distant, and is much 
more saline than the others. The first three are alkaline, the 
sulphur spring strongly so, while the fourth contains in solution 
a great quantity of earthy chlorids. : ; 
None of these waters are what are called “acidulous saline,” a 
aia which is due to the presence of large quantities of car-
