the proportion of their chemical elements. Of these are the 

 Albany Artesian Mineral Wells ; also Reed's Mineral Spring, 

 in South Argyle, and Halleck's, in Oneida County, near 

 Hampton. 



Of chalybeate waters, New York claims also to possess 

 a number of springs ; of these are Sandlake Tillage Spring, 

 in Rensselaer County, and others in Columbia, Dutchess, and 

 Delaware counties. 



Of the class of sulphureous waters New York has a large 

 supply, as, according to Dr. Bell, " There is scarcely a single 

 county in the State in which the springs of this class, im- 

 pregnated with sulphuretted hydrogen, are not found ;" and 

 the geologists report a large number in some of the districts. 

 Though widely separated, they have one common character 

 with regard to temperature and mineral composition which 

 would seem to point to a common geological origin. Be- 

 sides sulphuretted hydrogen, these waters contain carbonic 

 acid, carbonate and sulphate of lime, and some of them car- 

 buretted hydrogen. 



SHARON and AVON are the most celebrated sulphur 

 springs in New York. 



SHARON SPRINGS are near Leesville, Schoharie County. 

 They are called the " White Sulphur," and "Magnesian ;" they 

 come, according to Dr. Beck, " from the pyritous slates be- 

 neath the Helderburg limestone series." Dr. Chilton reports 

 White Sulphur to contain, in a pint of water, 



Sulphate of magnesia, 2 '65 grs. 



Sulphate of lime, 6 '68 " 



Chloride of sodium, 0*14 " 



Chloride of magnesium, 0*15 " 



Hydro-sulphuret of sodium and calcium, each 0'14 " 

 With one cubic inch of sulphuretted hydrogen gas. 



Drs. Beck and North differ in this analysis. 



MAGNESIAN SPRING has a slightly different composition, 

 containing, like the other, sulphuretted hydrogen, according 

 to the analysis of Professor Reed, of New York.
