Flame and Combustion [PDF]

open access: bronzeNature, 1927
IN commenting upon our previous letter in NATURE, Oct. 2, Prof. Armstrong stated that, in comparing the heats of combustion of carbonic oxide and hydrogen in flames, he had taken into account the heat of formation of water, not that of hydrone (steam), which can only mean that he supposes water (not steam) to be formed in flames. This being so, will he
