From these analyses it follows that the per 
centage of ash is 3,3, and that 100 grs. of the ash 
contain of— 
Phosphoric acid . 18 273 
Sulphuric acid . 0.224 
Potash . 15.23 8

Sulphate of lime. 1.616 
Phosphate of lime (trihasic). . 4*2 022 
Silicic acid . 0.404 
100.000 
Deducting the carbonic acid, we obtain the 
following per centage composition :—
