Experiment X. 



V^hakcoal from Norway Pine, 



Composed of oxide of carbon 98* 1 79 

 Ashes - - 1 821 



100 parts, 



15 grains of this charcoal were mixed with 200 grains of 

 oxide of iron. The fusion of this compound afforded a me- 

 tallic button that weighed 40 grains, equal to 20 per cent. 



75 grains of Norway pine, requisite to 15 grains of its 

 charcoal and 200 grains of oxide of iron, produced a metal-
