932 AN ANALYSIS 
water, are muriate of soda, muriate of magnesia, muriate of 
lime, and sulphate of soda. The quantity of muriate of soda 
is less than what is obtained by evaporation, for a portion of it 
is formed by the decompositions which occur; the quantity of 
muriate of magnesia is larger, as a portion of it is decompo- 
sed ; the quantity of muriate of lime is inferred from the quan- 
tity of sulphate of lime ; and the quantity of sulphate of soda 
is determined from the quantities of sulphate of magnesia and 
sulphate of lime obtained. The proportions may thus be easily 
assigned. Referring to the preceding analyses, the propor- 
tions in a pint, according to this principle, will be the follow- 
ing : 
According to the first analysis,. 
Muriate of Soda, - 170.2 grains. 
Magnesia, 30.6 
Lime, - 5.8 
Sulphate of Soda, - 21.9 
228.5 grains. 
According to the second analysis : 
Muriate of Soda, * 165.2 
— Magnesia, 31.6 
-—— Lime, - 5.9 
Sulphate of Soda, - 24.9 
227.6 
If the opposite view be adopted, that the sulphate existing 
in sea-water is not sulphate of soda, but sulphate of magnesia ; 
then the ingredients and their proportions will be as follow :
