But, as I have stated above, this decomposition yields, instead of ether, water and 
olefiant gas. 
I have prepared several of the salts of tetrethylammonium. The sulphate, the 
nitrate, the phosphate, the carbonate, the hydrochlorate and the hydrobromate, 
all crystallize. But these salts are extremely soluble, and, with the exception 
of the carbonate, deliquescent, and but little adapted to analysis. They may be 
obtained either by directly saturating the oxide with the respective acids, or by double 
decomposition. The phosphate is conveniently prepared by gently heating a solu- 
tion of the iodide with an excess of phosphate of silver, when, according to the silver- 
salt employed, either the common phosphate, or the pyrophosphate, &c. may be ob- 
tained. The phosphate thus obtained is strongly alkaline, like the tribasic soda- 
salt. 
Tetrethylammonium forms a great number of beautiful double salts, of which I 
have examined a few. 
Platinum-salt . — On adding a solution of bichloride of platinum to the chloride, 
an orange-yellow precipitate appears at once, which in every respect resembles the 
corresponding potassium- or ammonium-compound. 
Like the latter, it is slightly soluble in water, and less so in alcohol and in ether; 
like the latter, it may be crystallized in beautiful octahedrons. The salt was repeat- 
edly prepared. The specimens used for analysis I., II. and III., were precipitated 
from the pure chloride obtained by saturating the oxide with hydrochloric acid ; 
specimens IV. and V., simply by removing the iodine from the iodide by nitrate of 
silver, acidifying with hydrochloric acid, and adding bichloride of platinum to the 
mixture of nitrate and chloride thus obtained. The latter circumstance may have 
caused the trifling discrepancy, which will be observed in the numbers below. 
I. 0*3837 grm. of platinum-salt gave 0*4065 grm. of carbonic acid, and 0*2100 grm. 
of water. 
II. 0*3586 grm. of platinum-salt gave 0*1056 grm. of platinum. 
III. 0*2784 grm. of platinum-salt gave 0*0816 grm. of platinum. 
IV. 0*5228 grm. of platinum-salt gave 0*1526 grm. of platinum. 
V. 0*6782 grm. of platinum-salt gave 0*1977 grm. of platinum.
