Analysis of the Ash of the Blood of the Ox. By M. Weber. 



The entire blood was carbonized by the method stated. 



Aqueous extract. — The blood requires to be washed for nearly 

 fourteen days to obtain a proper extract for the first portion 

 of the analysis. 



The residue of the aqueous extract consisted of — 



Chloride of sodium 59-3n rNa CI . . 59-31 

 14.-67 KO, SO3 . 0-78 



11-91 I 3KO, PoO. 1-58

 Sulphuric acid .

The small quantity of free alkali which is produced by the 

 action of the carbon upon the alkaline carbonate, and which 

 is considered as hydrate of soda, might perhaps be regarded 

 more correctly as alkaline carbonate. 



Muriatic extract. — This consisted of — 



Soda ...... 41-39 



Potash 12-60 



Lime ...... 6-95 



Magnesia 4-10 



Peroxide of iron . . . 21-60 



Phosphoric acid . . . 13-36

The amount of alkali present is very striking, and is much 

 too large to allow of the supposition that the alkalies com- 

 bined with phosphoric acid had existed in the form of double 

 salts with the earthy phosphates. The quantity of phosphoric 

 acid found is exactly sufficient to form with the lime SCaO 

 + 3PO5, and with the magnesia 2MgO + PO5. The quantity 

 required by calculation is 13*62 per cent.; that found amounts 

 to 13-36 per cent. Probably the alkalies existed as chlorides 

 in the carbonized mass which had been exhausted with water, 

 and had escaped its action. This is rendered more probable 

 by the fact, that the sum of the constituents of the muriatic 

 extract, including the alkalies, amounted to much less than 

 the direct weight of the evaporated residue.
