These equations represent only the quantitative relations between the constituents 
of the powders and the products of explosion, and, accordingly, fractions of atoms 
and molecules are admissible. 
Experiments XIX. and LXXV. were made with F. G., Experiments IV. and 
XXXIX. with R. L. G., and Experiments XIV. and LXXVIL with P. powder of 
Waltham Abbey. 
It will be noticed by comparing two experiments, made with the same description 
of powder, that the composition of the powder deduced from one of the experi¬ 
ments exhibits considerable differences from the composition derived from the other 
experiment, and neither of them agrees with the composition found by direct 
analysis. 
The composition of the R. L. G. powder may serve as an example. 
According to Experiment IV. . . 16KNO 3 +20*7C +6-65S+4-630

The products of combustion of Experiment IV. contain 1*2, and of Experiment 
XXXIX. 3 atoms more carbon than the powder used in these experiments, or in 
other words: the products of explosion in Experiment XXXIX, were found to 
contain 1'67 per cent, more carbon than the R. L. G. powder which was exploded.
