On treating the solution of the iodide with oxide of silver, a very caustic solution of 
the oxide is obtained. 
Chloride of Tetramethylphosphonium and Bichlonde of Platinum. 
The solution of this oxide, mixed with hydrochloric acid and bichloride of platinum, 
furnishes a platinum-salt which is insoluble in alcohol and ether, but crystallizes from 
water in beautiful octahedra. It contains 
Cg Hi, PCI, PtCl,=Me, PCI, PtCl,. 
By analysis, 0-6365 grm. of the platinum-salt gave 0-2120 grm. of platinum.
