§ V. 
Second Analysis of the Dead Sea Water by a Method somewhat 
different from the former. 
In the mode of proceeding just related, some small loss in 
the earths might naturally be suspected to have taken place 
in consequence of the previous separation of the acid and in- 
dispensable edulcorations. Besides, the muriat of soda being 
necessarily decomposed by the first part of the process, the 
analysis could not have been considered as quite satisfactory, 
had not the common salt been procured unaltered by some 
other process. 
1. In order to obtain these points, 150 grains of the water 
were treated, with regard to the lime and magnesia, exactly 
as in the former analysis ; but in this case, the acid, instead of 
being actually separated by silver, was only calculated from 
the former estimation (§ IV. 5). 
2. The result proved perfectly agreeable to my expecta- 
tion. It yielded a little more lime and magnesia than the 
former analysis, but this excess was scarcely perceptible. 
With regard to the muriat of soda, I was able actually to 
procure by evaporation, as much as 13,1 grains of this salt, the 
actual quantity of which, inferred as in the preceding analysis, 
was 15,54 grains, a difference easily accounted for by the 
necessity of heating the salt to redness for its ultimate sepa- 
ration. 
3. On summing up the contents of these Uo grains of the 
water, they appeared to be as follow :
