Hence, taking the gas-measurement and analysis combined as the basis of calculation, 
we have : — 
Gaseous products = 180-318 grms. Solid products = 230-767 grms. 
or, if we take the mean of the two determinations as more nearly representing the truth, 
Solid products = 234-242 grms. = -5698 
Gaseous products . . . . = 176-843 grms. = -4302 
Resolving the solid products of combustion into their elements, we have the follow- 
ing scheme : —
