Chemical Examination, by Mr. C. U. Suzparn, Assistant in the 
Chemical Department of Yale College. 
This is a sulphureous water, as is perfectly obvious to the smell 
and taste. 
A. Twenty four ounce measures of the water boiled ina retort for 
half an hour, gave over two and a half inches of gas, which appeared 
to be a mixture of sulphuretted hydrogen and azote. It possessed 
the odor of the former of these gases, and extinguished a lighted 
match, which was introduced into it. The water, after boiling, ex- 
hibited a copious precipitate and still continued to emit the odor of 
sulphuretted hydrogen gas; the smell of which was increased upon 
the addition of a little sulphuric acid, from which circumstance it ap- 
pears probable that the sulphuretted hydrogen is not wholly free, but 
in part engaged with a basis, probably lime, in the form of a hydro- 
sulphuret. 
B. Litmus paper, introduced into the water before boiling, was 
unchanged ; but after being first reddened by a little acid, it had its 
blue color restored ; indicating the presence of carbonate of soda or 
potash. Tincture of alkanet was immediately changed to blue, by 
the boiled water. 
C. Muriate of lime gave a precipitate with the water, proving the 
Presence of carbonate of lime. 
- Muriate of barytes gave a precipitate with the water, proving 
the presence of a sulphate or carbonate, probably lime, the substance 
Precipitated by boiling (in A.) 5 ; 
- Nut galls and prussiate of potash, gave no indications of iron. 
F. The addition of muriatic acid produced a distinct effervescence 
in the water, owing either to sulphuretted hydrogen or carbonic acid, 
or to both 
G. The addition of carbonate of ammonia, and afterwards of phos- 
Phate of soda, gave a copious precipitate, proving the existence of 
Carbonate of magnesia. 
It appears then to be a strong sulphureous water, free from any 
Meombined carbonic acid, and containing notable quantities of the 
Carbonates of lime, magnesia and soda, together with sulphate of lime.
