Analysis of the Saline Springs of Keio York. 345 



2. The deliquescent salts were extracted from the dry 

 residuum by digestion in alcohol, and separated from each 

 other by convertins; them into sulphates in the usual way. 



3. The mass, after the separation of the deliquescent 

 salts, was dissolved in water and filtered. The carbonate 

 and sulphate of lime left on the filter were separated by mu- 

 riatic acid, &;c. 



4. The filtered solution was treated with carbonate of 

 soda, boiled, and filtered; the carbonate of lime left on the 

 filter indicating the quantity of sulphate of lime, decompo- 

 sed. 



5. To the last clear solution, neutralized by the addition 

 of muriatic acid, muriate of barytes was added till it ceas- 

 ed to yield a precipitate ; the quantity of sulphate of bary- 

 tes shewing that no other sulphate existed in the water.
