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 pints 

 of sea-water, and their proportions, are as follow :
