Oneida County. Halleck's Spring, in this county, appears to deserve a notice under the 

 liead of carbonated springs. It is situated about half a mile northeast of the village of Hamp- 

 ton, 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 grs. 



This spring evolves carburetted hydrogen in considerable quantities, together with a minute 

 portion of carbonic acid. The composition of the water is quite similar to that of the weak 

 brine springs, to which it perhaps more properly belongs. 



The following springs, which may be arranged under this division, deserve only a brief 

 notice. 



In Rensselaer County, about a mile west of the village of Sandlake, there is a strong and 

 copious chalybeate spring, wliich issues from the gi'avel. 



In Essex County, near Crown Point, is a spring which, according to Dr. Emmons, has a 

 specific gravity of 1.014, and 1000 parts of wliich contain 1 8 . 78 parts of saline matter. This 

 saline matter consists principally of sulphate of magnesia, with a portion of sulphate of lime.* 



In Greene County, there is a strong chalybeate spring near Catskill. Several of a similar 

 kind occur in the Counties of Dutchess,' Columbia and Delaware. It is probable that 

 the oxide of iron which they deposit has originally been held in solution by carbonic acid.
