bonic acid, the quantity of this acid found, being in no case more 
than is required to form bicarbonates with the bases present. 
. The Gas Spring.—The waters of this spring were collect- 
ed on the 27th of September, 1847. *'The temperature of the 
air being 617° Fahrenheit, that of the spring was 44:4. The 
discharge was ascertained by careful measurement to be four gal- 
lons per minute, a quantity which is little subject to variation. 
‘The water in the well is kept in constant agitation by the escape 
of carburetted hydrogen gas, which is evolved in considerable 
quantity. It was roughly estimated at the time, to be three hun- 
dred cubie inches a minute, but the discharge as I was informed, 
is often much more abundant. 
The specific gravity of the water was found to be 1006-2. It 
is pleasantly saline to the taste, but not at all bitter; by exposure 
to the air it gradually deposits a white sediment of earthy carbon~ 
ates. Its reaction is distinctly alkaline to test papers. 
e examination of the unconcentrated water shewed the pres~ 
ence of chlorine, calcium and magnesium, but when the liquid is 
concentrated by boiling, these bases are wholly precipitated as 
carbonates, and the clear liquid is alkaline, yielding with a solu- 
tion of chlorid of barium, a copious precipitate of carbonate which 
is dissolved by hydrochloric acid, leaving ouly a small quantity 
of sulphate of baryta. The alkaline liquid being evaporated to 
dryness, and the residue digested with alcohol, the solution gave 
evidence of the presence of both bromine and iodine; the saline 
residue was found to consist of salts of sodium with a small por-

salts were precipitated, the respective amounts of the calcium and 
magnesium, both in the precipitate and filtrate, were determined, 
and those in the latter, regarded as corresponding to the chlorids 
and sulphates of those bases, in the recent water. The alkalies 
were separated by successive treatment with baryta and carbonate 
of ammonia, and the amount of potassium in the mixed chlorids 
‘vas then determined by converting them into the platino-chlorids, 
and separating the sodium salt by alcohol.
