magnesia half a grain. In this manner these two salts were separated 

 from each other, and the amount of each determined as it exists in the 

 mineral water. 



Examination of the Solution by cold distilled Water. 



7. This was evaporated slowly in a temperature not exceeding 

 eighty degrees of Farenheit. No pellicle or crystal formed on its 

 surface ; its taste was insipid to the last. The extract was nearly all 

 soluble in dilute muriatic acid. What the acid left, after being washed, 

 was taken up by alcohol, and amounted to 0.10 gr. of extractive. 



To the muriatic solution, ammonia was added until it tasted alkaline ; 

 no change appearing, the mixture was heated, but it still remained clear, 

 and gave no sign of magnesia. On trying it, however, with oxalate of 

 ammonia, there ensued an immediate precipitate. Consequently the 

 substance dissolved by the muriatic acid was carbonate of lime, and 

 its amount was equal to 4.40 grs. 



Examination of the Solution by Acetic Acid. 



8. The residuum, insoluble in alcohol and water, was digested in dis- 

 tilled vinegar for twelve hours, and occasionally shaken. A little being 

 tested in the small tube with oxalate of ammonia, it was found to hold 

 lime, and another small portion being tried with caustic ammonia, the 

 presence of magnesia was also proved. But these earths must have 

 previously existed in the state of carbonates. 



The acetous solution evaporated to dryness, gave a whiter extract 

 than any yet obtained. By remaining exposed to the air all night, it 

 attracted a little moisture, corroborative of its containing acetite of 

 magnesia. The evaporated solution weighed 6.35 grains. It dissolved
