238 AN ANALYSIS 



The proportions of the compound salts may be assigned from 

 these, according to whatever view may appear most probable, 

 of the state of combination in which they exist in sea-water, 

 and thus the results may be compared with those of the former 

 analyses. 



Thus, supposing the elements to be combined in the modes 

 in which they are obtained by evaporation, that is, as muriate 

 of soda, muriate of magnesia, sulphate of magnesia, and sul- 

 phate of lime ; the proportions of these salts in a pint, will 

 be 



Muriate of Soda, - 180.5 grains. 



Magnesia, - 23 



Sulphate of Magnesia, - 15.5 

 Lime, - 7.1 



226.1 



Supposing that the lime exists as muriate of lime, (which is 

 the most probable conclusion with regard to it), and farther 

 supposing, that the sulphuric acid exists in the state of sul- 

 phate of magnesia, the proportions will be 



Muriate of Soda, - 180.5 grains. 



Magnesia, - 18.3 



Lime, - 5.7 



Sulphate of Magnesia, - 21.6 



226.1 grains. 



Or, lastly, supposing that the sulphuric acid exists in the 

 state of sulphate of soda, the proportions will be 



Muriate
