earth amounted to 21.5 per cent. From the filtered solution 

 a trace of iron was detected by ammonia, and a trace of lime 

 by the oxalate of ammonia. 



The muriatic and sulphuric acids were precipitated in the 

 usual manner from a solution in acetic acid. The quantity of 

 fused chloride of silver, procured from 8.775 grains of the sa- 

 line mass, amounted to 4.082 grains, equivalent to 1.000 grain, 

 or 11.47 per cent, of chlorine. This quantity of chlorine was 

 united in the solid contents of the spring with 7.648 parts of 

 sodium. The sulphate of baryta, after being heated to red- 

 ness, weighed 2.783 grains, equivalent to 0.94 grains, or 10.74 

 per cent, of sulphuric acid. This quantity of acid must have 

 been united with 8.593 parts of soda. 



According to this analysis, 300 parts of the solid contents of 

 the mineral spring at Pinnarkoon, contain, 



Silica, - - - 21.50 



Soda, - - 24.84 



Sodium, (united with chlorine,) - 7.648 



Chlorine, (united with sodium,) - 11.470 



Sulphuric acid, - 10.74 



Carbonic acid, - 7.786 



Water, with a little organic matter, - 15.544 

 Oxide of iron and lime, - - Traces.

 Or, by adding the chlorine and the carbonic and sulphuric 

 acids to their equivalent quantities of sodium and soda, the 

 constituents are as follows : 



Silica, - - - 21.50 



Chloride of sodium, - \ 19.118 



Sulphate of soda, - - 19.333 



Carbonate of soda, - - 19.109 



Pure soda, - 4.924 



Water, with a little organic matter, - 15.544 

 Oxide of iron and lime, - - Traces.

 The analysis does not account for the sulphurous smell and 

 taste reported by Mr Breton. Perhaps the sulphuretted hy-
