hydrochloric acid, precipitated with sulphate of soda = *059 grain of baryta. 
= -022 grain of phosphorus. 
=0*1 per cent, phosphorus. 
13-53 grains of the substance, fused with 69 grains of nitre, and the same quantity 
of carbonate of potash, gave 1*17 grain of sulphate of baryta. 
=0'1614 grain of sulphur. 
= ri9 per cent, sulphur. 
The clear liquid precipitated by ammonia — 
Phosphate of baryta =*29 
Phosphorus ........ =*041 
Sulphate of baryta =*16='10 baryta 
Hence phosphorus ='30 per cent. 
11-88 grains of the substance, fused with 55 grains of nitre and the same quantity 
of carbonate of potash, gave -97 grain of sulphate of baryta. 
= ‘1338 grain sulphur. 
= 1-12 per cent, sulphur. 
The clear liquid precipitated by ammonia — 
Phosphate of baryta =-25. 
Phosphorus =:-0349. 
Sulphate of baryta =-14= 9 baryta. 
Hence phosphorus =‘29 per cent. 
There is, then, deducting the sulphur and phosphorus dissolved out by the boiling 
hydrochloric acid, — 
Sulphur, per cent. . . . 
Phosphorus, per cent. . .

The presence of sulphur and phosphorus in this new substance proves that it is not 
an oxide of protein. The solubility of this body in water might lead to the compa- 
rison of it with the hydrated tritoxide of protein of Mulder, which is also soluble in 
water ; but according to Mulder, this hydrated tritoxide of protein gives no preci- 
pitate on the addition of ferro-prussiate of potash, and it contains no sulphur or 
phosphorus, while this new substance gives both sulphur and phosphorus, and also 
a precipitate with ferro-prussiate of potash. In these respects there is a most 
marked and essential difference between these substances. The peculiar reaction of 
this new body with nitric acid, the solubility of the nitric acid precipitate when 
heated, I find to be also common to the so-called hydrated tritoxide of protein pre- 
pared from the inflammatory crust of the blood ; from albumen of the blood by 
chlorine ; and from albumen of the egg. Lastly, this peculiar reaction with nitric 
acid hinders all possibility of confusing this new substance with albumen. Indeed 
ordinary albumen may be separated from this new substance by adding nitric acid.
