214 AN ANALYSIS 
acid, excited effervescence ; the liquor poured off afforded by 
evaporation muriates equivalent to 2.8 of carbonate of magne- 
sia, and 1.3 of carbonate of lime. And the remaining sulphate 
of lime dried weighed 3 grains. 
By this analysis, then, the substances obtained from 4 i 
of sea-water, and their proportions, are as follow : 
Muriate of Soda, - - 728.5 grains.
