The reconciliation between the amounts of C, O, H and N, contained originally in 

 the explosive, and found in the products of explosion, were obtained as follows : 



Multiplying the carbon, oxygen, and nitrogen by 12, 16, and 14 respectively, we 

 obtain : - 



In this experiment the quantity of gas and water measured shows that 1 gramme 

 of M.D. under the pressure named above gave rise to 788 '4 cub. centims. of 

 permanent gases, or to 946 '4 cub. centims. including aqueous vapour.
