The water of the springs has no perceptible taste, and only a very- 

 faint smell of sulphur is perceived. No gas escapes from it, but a white 

 incrustation covers the stones over which the water flows. 



Some of these waters were obtained, and since our return were put 

 into the hands of Dr. C. T. Jackson, of Boston, who gives the following 

 analysis : 



Specific gravity, T0043; thermometer 60° ; barometer 30-05 in.

 distilled water, on evaporation gave —
