CANADA SPRINGS. 189 



rides of magnesium and calcium, bromide of magnesia, and 

 sulphate of lime. The leading elements are chlorides of 

 sodium, magnesium, and calcium. (Hunt.) 



The CALEDONIA SPRINGS are about forty miles from Mon- 

 treal, near the Ottowa River. There are four founts, three 

 known as Saline Spring, Gas Spring, and White Sulphur 

 Spring. 



GAS SPRING has a temperature of 44 F., and is highly 

 charged with carburetted hydrogen, also containing chlo- 

 rides of sodium and potash, sulphates of potash, bromide of 

 sodium, iodide of sodium, (??) carbonates of soda, lime, 

 magnesia, iron, and manganese, with alumina, silica, and 

 carbonic acid. This extensive catalogue of ingredients em- 

 braces half the pharmacopoeia, and, like some of the more 

 ancient formulae or medical prescriptions, contains a small 

 touch of everything. A SAFE WATER under all circum- 

 stances, as a widely scattering shot will certainly hit some- 

 thing. 



This is Gas Spring, (certainly gaseous ! !) 



SALINE SPRING is said to be similar to the one last de- 

 scribed in chemical composition ; temperature being 45 F. 

 Differs from last in quantity of free carbonic acid, otherwise 

 qualitative analysis same as above. 



SULPHUR SPRING. This spring is in the immediate vicinity 

 of the last, and contains a smaller quantity of sulphur, " a 

 trace of sulphur rather than a quantitative return." It 

 also contains carbonates of soda and magnesia, with traces 

 of iron, iodine, and silica. The leading element is the soda, 

 the water being described as "strongly alkaline." There is 

 an intermitting spring a few miles from the others mentioned. 

 The water contains chlorine, bromine, and iodine, with po- 

 tassium, sodium, calcium, and magnesium, some of these ex- 

 isting as chlorides, with traces of iron and alumina. 



At ST. CATHARINES, Canada West, there is an Artesian 

 well of most miraculous composition and consequent power. 

 The water has more solid contents than fluid, and is mani- 

 festly an extraordinary product of Nature. Its " table of
