Oneida County. HallecVs Spring, in this county, appears to deserve a notice under the 

 head 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 maybe 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, which issues from the gravel. 



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 which contain 18.78 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.
