 chalybeate spring, which can scarcely be called a mineral 

 water. 



In RAWDON TOWNSHIP there are two springs, both of 

 which are alkaline, and the first a water containing earthy 

 and alkaline carbonates, with alkaline chlorides, and small 

 portions of sulphates, borates, and a trace of bromine, but 

 no iodine. The second spring is strongly saline, and dis- 

 tinctly alkaline to the taste. Plantagenet new saline springs, 

 neutral, strongly saline, carbonates small, earthy chlorides 

 strong, also iodine and bromine.

 air, 52 ; also strongly saline ; when concentrated, very alka-

 They contain only a little sulphate of lime and traces of 

 chlorides. 



In Toronto is also a well of similar composition ; also a
