1889.] XEW YORK ACADKMY OF SCIEKCES. 41 



Lime 1, 380.00 grs. 



Magnesia 378.40 " 



Potash 446.00 *' 



Chlorine 1,267.00 '' 



Bromine 46.60 " 



Sulphuric acid , 1.00 " 



If the brine from this well shall prove to be abundant in quan- 

 tity, it may become valuable as a source of potash ; and this 

 discovery indicates the possibility of finding in the great salt-field 

 of the Salina group some localities where potash and the asso- 

 ciated salts produced in such quantity at Stassfurt, may be found 

 and may become an object of exploitation. Among the wells of 

 "western New York in which salt has been found are two at Mt. 

 Morris, about 1,600 feet deep ; Greggsville, six miles north of 

 Mt. Morris, four wells 990 to 1,030 feet deep ; Le Koy, eight 

 miles west of Greggsville, two wells 850 to 900 feet deep. 

 Other wells have struck salt at East Avon, Batavia, Geneseo, 

 York Station, Phillips, Piffard, Livonia, and East Aurora. A 

 well at Piffard penetrated the following strata : —
