about half a mile northeast of the village of Hampton, in the town of 
Westmoreland, and was the result of a boring into a solid rock of a 
hundred and six feet. The following is the composition of one pint of 
this water, according to the analysis of Prof. J. Noyes, formerly of 
Hamilton College. 
Chloride of sodium, 78.00 grains. 
Chloride of calcium, 13.00 " 
Chloride of magnesium, 4.00 " 
Sulphate of lime, 5.00 " 
100.00 " 
This spring is highly charged with carburetted hydrogen, and contains 
a small quantity of carbonic acid. 
JVew-Fw/c Spring, — The only remaining spring to be noticed imder 
this head, is the one opened some years since in Cliff-street, in the city 
of New- York, of which an analysis was made by the late Mr. George 
Chilton. If the published results are correct, this water is more com- 
plex in its composition than any hitherto found in this State. A pint of 
this water contains 18.74 grains of saline matter, and 9.14 cubic in- 
ches of carbonic acid and atmospheric air.* 
Sulphuretted, or Sulphureous Springs. 
Sulphuretted springs, or such as have their waters charged with sul- 
phuretted hydrogen gas, are of very frequent occurrence in this State. 
Indeed, there is scarcely a single county in which they are not found. 
They may of course always be known by their unpleasant odour, and if 
strongly charged with the gas, by the effect which they have of black- 
ening silver and the solution of sugar of lead. 
Sulphur Springs on the Hudson. — Commencing in the southern part 
of the State, sulphuretted springs are found at short intervals, from near 
Sing-Sing, in Westchester county, to Fort-Miller, in Washington coun- 
ty, a distance of nearly a hundred and fifty miles. They occur on both 
banks of the Hudson, and usually rise through the strata of glazed black 
slate which is found throughout nearly the whole of this extent. Under 
this head, may be enumerated the Chappequa mineral spring, three and 
a half miles east of Sing-Sing; one near the village of Newburgh; one 
in the city of Hudson; the springs at Coeymans' Landing; in Guilder- 
land, in Wendell's hollow, in the city of Albany; in Watervliet; the
