CATARACTS, AND INUNDATIONS. 



carbonate of soda and muriate of barytes. No precipitation en- 

 sued ; a proof that it contained no sulphate of lime. 



In 100 parts of the \\ntrr brought by the Abb6 Mariti from the 

 lake of Asphalt urn, or Dead Sea, and examined by me, there were 

 contained, therefore, 



Muriate of magnesia 24'20 



Muriate of lime J O-6'O 



Muriate of soda 7*80 



42-60 



The result of these experiments approaches that of Macqner, 

 Lavoisier, and Sage. But the analysis of Pr. Marcet is a good 

 deal different, owing in all probability to the complicated processes 

 and calculations which he followed. 



The specific gravity of the water, as stated by the French che- 

 mists, agree.> likewise very nearly with mine. The sum of the saline 

 ingredients, as stated by these gentlemen, exceeds what I obtained 

 by l|- grains. This was probably owing to their being in a less degree 

 of dry ness; for it is well known, that the two earthy muriates ab- 

 sorb water from the atmosphere while cooling. 



The somewhat smaller specific gravity found by Dr. Marcet ren- 

 ders it probable that the water which he examined was collected 

 not far from the place where one of the streams of the river Jordan 

 falls into the Dead Sea. 



To give an example of the difference of the ingredients of this 

 water from those of the ocean, I make choice of the specimen of 

 sea-water which Sparrman drew in the month of July. 1776, in the 

 latitude of the Canary Islands, from a depth of 60 fathoms, and 

 which Bergman analysed. He found its specific gravity rO^SQ; 

 and a Swedish kaniie 100 Swedish cubic inches gave him
