tions. Muriate of soda remained, which weighed 180.5 grains, 

 equivalent to 96.3 of soda, and 84.2 of muriatic acid. 



This gives the quantity of Soda contained in the sea-water ; 

 but it does not necessarily give the quantity of muriatic acid ;. 

 for if more of this acid be present than what the soda can neu- 

 tralize, combined with portions of any of the other bases, (and 

 from the former analysis this appears to be the case,) this 

 quantity will be combined with ammonia in the preceding 

 steps of the analysis, and is of course dissipated in the state of 

 muriate of ammonia. 



This will appear, and the quantity be discovered by ascer- 

 taining what proportion of these bases the quantity of sulphu- 

 ric acid obtained by the analysis is capable of neutralizing, 

 thus finding if any excess of them remain ; and, from the quan- 

 tity of this, discovering the quantity of muriatic acid, which 

 would be requisite for saturation, which of course is the 

 quantity lost. 2.9 of lime, the quantity of this earth obtained 

 by the analysis, neutralize 4.1 of sulphuric acid; this deduc- 

 ted from 14.4, the quantity obtained, leaves 10.3, to neutralize 

 which, 5.1 of magnesia are required ; this deducted from 14.8, 

 the quantity of magnesia, leaves 9.7 of that earth ; to neutra- 

 lize this, 13.5 of muriatic acid are required ; and this added to 

 the 84.2 in the muriate of soda, gives 97.7 grains as the total 

 quantity of Muriatic Acid.
