In this set of experiments the proportion of carbonic oxide burnt gradually 
increases as the length of the path of the explosion is increased. It is evident, 
therefore, that under pressures as low as 200 millims., one of the conditions which 
affects the division of the oxygen is the shape of the vessel containing the gases. In 
the last experiment the gases were fired at a temperature of 85° C. The increase of 
initial temperature acts in the same way as an increase in the length of the columns. 
A second series of experiments was then made with another mixture containing 
equal volumes of carbonic oxide and electrolytic gas. Portions of this mixture were 
exploded alternately at the line 200 in the eudiometer and between the lines 700 and 
800. The pressure in every case was 250 millims., the temperature near 10° C.

the same number in the Appendix the details of that experiment will be found.
