DR. BENCE JONES ON A NEW SUBSTANCE 
3'57 grains, minus ash, gave 6'84 carbonic acid and 2*24 water.

2-85 grains of the substance of the 1st preparation, minus ash, gave 6-89 arnmonio- 
chloride of platinum.

4-37 grains of the 2nd preparation, minus ash, gave 10'27 grains ammonio-chloride 
of platinum.

5 grains of the substance, mixed with 50 grains of pure nitre, free from chloride and 
sulphate, heated gently in a platinum crucible, inflamed (some was lost) ; the residue, 
dissolved in water acidulated with pure nitric acid, gave no precipitate with nitrate 
of silver ; but gave a very plentiful precipitate with chloride of barium, insoluble in 
nitric acid, when boiled. After being filtered it gave a cloud with ammonia, soluble 
in acid, reprecipitated by ammonia. 
Previously to determining the sulphur in this substance, I determined the quantity 
present in some dried albumen from an egg. Treated with hydrochloric acid, it gave 
scarcely a trace of precipitate with chloride of barium. 
9 grains of dry albumen, fused with 45 grains of nitre, and the same quantity of 
pure carbonate of potash, gave *83 grain of sulphate of baryta. 
= -11 grain of sulphur. 
= 1-27 per cent, sulphur. 
9*56 grains of the new substance, fused with 45 grains of nitre, and the same quan- 
tity of carbonate of potash, gave 1*01 grain of sulphate of baryta. 
= -139 grain of sulphur. 
= 1-45 per cent, sulphur. 
Some of the substance, prepared at a different time, was next examined. 
20'67 grains, when treated with boiling dilute hydrochloric acid for about half an 
hour, gave *17 grain of sulphate of baryta. 
= '023 grain of sulphur. 
= ‘09 per cent, sulphur. 
The clear liquid, after separation of the sulphate of baryta, precipitated by ammo- 
nia, filtered, washed with boiling water, burnt, redissolved in hydrochloric acid, and 
reprecipitated by ammonia, gave -16 grain of phosphate of baryta; redissoh^ed in
