The amount of solid matter in 1000 parts of the water is by 
calculation 7-347 ; experiment gave 7°280, which is a close ap- 
proximation. The carbonate of magnesia loses a part of its car- 
bonic acid during the evaporation, and exists in the residue as a 
basic carbonate; hence the slight deficiency in the result of ex- 
periment. 
The quantity of carbonic acid, above what is represented as 
combined with the bases, equals 14:7 cubic inches in 100 cubic 
inches of the water. 
If. The Sulphur Spring.—This spring is situated very near 
to the last; the openings of the two wells being not more than 
four feet apart. Although it bears the name of a sulphur water, 
its claim to that title is very small. It has a feebly sulphurous 
taste and odor, and darkens slightly salts of lead and silver, but 
the quantity of sulphur existing either as sulphuretted hydrogen 
or as alkaline sulphuret is very inconsiderable, and cannot be 
quantitatively estimated by the ordinary processes. 
everal bottles of the water were mixed with a solution of 
arsenic at the spring, but the precipitate of sulphuret of arsenic 
was scarcely perceptible ; the quantity of the sulphuretted hydro- 
gen was not equal to a cubic inch toa gallon. It is still, how- 
ever sufficient to impart medicinal powers to the water, for the 
eflicacy of this spring over all the others in rheumatic and cuta- 
neous affections is well attested. According to Dr. Stirling, who 
as been for many years a resident at the springs, and is a careful 
Observer, the water was formerly much more sulphurous than at 
present; a thing not at all improbable, as it is well known that 
Springs often change their character materially in the course of a 
few years. 
The supply from this spring is apparently about the same as 
that of the “Gas Spring ;” its waters flow into the same reser- 
Voir as those of the saline springs, and the two are used for hot 
ths. The mixture, after being heated for use, is without any 
odor of sulphur. 
‘he temperature of the spring was found to be 46° F*., that of 
the air being 60° F. The specific gravity of the water at 60° F. 
is 1003-7; its reaction is strongly alkaline, and the results of its 
qualitative examination show that it closely resembled the two 
ets waters, except that only traces of iodine were detected 
it.
