 There is probably a loss of carbonic acid. The theoretical combina- 

 tion of bases and acids would give : 



Carbonate of soda 0.24944 



Sulphate of soda 0.04498 



Chloride of sodium 0.39571 



Chloride of potassium 0.11617 



Carbonate of lime 0.03143 



Carbonateof Magnesia 0.05768 



SiHca - 0.03250 



Phosphoric acid 0.00069 



Less carbonic acid added to the amount found.
