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.% 
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
