Note on the preceding Paper . 
By W. Esson, M.A., F.R.S., Fellow of Merton College, Oxford. 
In January, 1882, Mr. Dixon sent to me the results of the experiments recorded on 
p. 659 of the preceding memoir, and asked me to discover if I could the relation 
between the quantities of the gases at the beginning and end of the explosion. The 
facts already discovered by Mr. Dixon (1) that the union of carbonic oxide and 
oxygen does not take place except in the presence of steam, and (2) that carbonic 
oxide is oxidized by steam at a high temperature, led me to conjecture that the first 
effect of the explosion was to combine all the oxygen present with the proper amount 
of hydrogen to form steam. An action was then set up between the steam and 
carbonic oxide resulting in the formation of hydrogen and carbonic acid, and
