contributed by Mr. Hugh Carleton on the 8th June, 1869, has a weakly 
acid reaction. It has a strong odour of sulphuretted hydrogen, and is 
slightly turbid from the presence of liberated sulphur. A slight sediment 
had formed in it, which was separated from the portion analyzed. 
The following is the amount and composition of the soluble matters 
contained in one gallon of it :—

This water is evidently an acidulous one, and is a moderately strong 
chalybeate. I have not heard of its being medically — but it certainly 
should possess some therapeutic virtue. 
A deposit formed by these springs has been also examined; itis a 
chocolate-coloured substance possessed of moderate coherence, and is 
spangled throughout with minute crystals of sulphur; reaction strongly 
acid.

4, Alkaline Water. 
Wie arrive at a water of a different kind from any of the 
preceding. It is an alkaline mineral water, and great interest in it was
