Note—The chlorine is assigned to calcium, as th 
oftener found in those waters which contain but little saline matter. There 
remains .006 sulphuric acid, apparently in excess, which is accounted for 
by the difficulty of separating, accurately, magnesia from the other earthy 
salts. The quantity of carbonate of lime considerably exceeds the equiv- 
alent quantity of carbonic acid, necessary to render it soluble in pure 
water, and this fact affords a probable explanation of the character this ” 
water exhibits, when tested by colored papers.” _ 
The “ upper spring” seems not to differ essentially from the. lower. 
In sensible properties, it bears a close resemblance to it : but there is a 
peculiar sweetness of taste, which distinguishes it. The deposit around 
it is mostly of a dark blue color, while that of the lower spring is hase 
It rises about sixty rods east of the other, aid is at an elevation considera- 
__ bly above it. The bed of sand, eagle which this water oozes, is about 
twenty feet, and the rock about thirty feet below the surface of the ground. 
One gallon from this spring, according to Prof. Hadley, of the institution 
of Fairfield, Herkimer County, New York, was found to contain the fol- 
sanida substances, and peers in the ein proportions, viz.

: And a small quantity of other matter. 
There are other springs in the neighborhood, but their qualities are 
essentially the same as those quoted. The geology of the vicinity is said 
__to be bituminous shale, upon transition limestone. Iodine and bromine 
. have not yet been detected in the constitution of these waters; but it is 
factory evidence of their containing iodine. re ne oe Rn ee 
14. A “Treatise on Gems, in reference to their pete od scientific 
value. A useful guide for the Jeweller, Lapidary, Artist, Amateur, 
Mineralogist, and Chemist ; accompanied by a description of the most 
interesting American gems, and ornamental and architectural materials 
By Dr. Lewis Feuchtwanger. New York, 1838.—The title of this work 
embraces a very correct idea of its contents. Dr. Feuchtwanger has col- 
lected-a great amount of information, drawn from many sources, in addi- 
tion to his own experience, both in regard to the scientific character, com- 
mercial value, history, and antiquity, not only of the gems, properly Se)
