XI. An Analysis of Sea-Water ; with Observations on the Ana- 
lysis of Salt-Brines. By Joun Murray, M. D. F.R.S. E. 
(Read 15th April, and 20th May, 1816. ) 
HE composition of Sea-Water has been variously sta- 
ted by different chemists, not only with regard to the 
peahradtisih of the salts which it holds in ews but with re- 
gard even to the ingredients themselves. 
According to Lavorsrer, it contains muriate of soda, muriate 
_of magnesia, and muriate of lime, sulphate of soda, sulphate 
of magnesia, sulphate and carbonate of lime. The pro- 
portions he assigns are, in'a pound of water, (French weights) 
126 grains of muriate of soda, 14% grains muriate of magnesia, 
23 grains muriate of lime mixed with muriate of magnesia, 
7 grains of sulphate of soda and sulphate of magnesia, and 8 
grains of sulphate and carbonate of lime *. 
BereMan gives a very different statement. He found only 
muriate of soda, muriate of magnesia, and sulphate of lime; 
the proportions in a Swedish kanne, which is equal to about 64 
English pints, are 2 ounces 433 grains of muriate of soda, 380 
) grains
