The amount of phosphoric acid required by calculation is 

 46-61 per cent.; that found by analysis amounts to 46-99 per 

 cent. 



Residuary carbonized mass. — The ash of this consisted of— 



Potash 36-64 



Soda 4-71 



Lime 1-88 



Magnesia 4*36 



Peroxide of iron . . . 0*76 



Phosphoric acid . . . 51*65

The precipitate thrown down by ammonia from the muriatic 

 solution of this ash, after having been heated to redness, 

 consisted of 2CaO, PO5 + 2MgO, PO5 + Fe^ O3. The phos- 

 phoric acid required by this formula amounts to 9-87 per cent.; 

 analysis gave exactly this quantity. The remaining 41-79 

 per cent, of phosphoric acid were neither wholly combined 

 with the alkalies as pyrophosphates, nor as metaphosphates. 

 The phosphoric acid is too large in quantity for the former 

 case, and too small for the latter. 



The relative amounts of ash in the flesh were as follows : — 



Extracted by water 42-81 



Extracted by muriatic acid 17*48
