SLQ WATER OF THE DEAD SEA. 



in great mca- This objection, however, is in a great degree removed, by a 

 «ate removed, comparison of the two portions of the solution, from one of 

 which the common salt can be obtained undecomposed ; 

 and the present method has this additional advantage, that 

 the quantity of acid is a sort of check, which, when con- 

 nected with some other point of comparison, prevents ariy 

 gross errour in the computation of the earths from escaping 

 notice. 



This plan being very similar to that which I actually fol- 

 lowed in the analysis of the water of the Dead Sea, it may 

 be worth while to mention the summary results of the com- 

 parative experiments which decided me in its favour. 

 The artificial solution contained :

 Analysis #/" the Dead Sea Water. 



Analysis of the I now come to the actual examination of the \Vater of the 

 Dead Sea wa- Dead Sea, the particulars of which will be found much short- 

 ened by the preceding observations. 



* These happened to be very nearly the real proportions of salts in the 

 Dead Sea ; yet this coincidence was a matter of mere accident; for when 

 I mixed up the ingredients, I was led to suppose from Lavoisier's paper, 

 that their proportion in the Dead Sea was very different from that which 

 I afterward aitcrtained.
