Appendix. 
1. In the following tables the actual numbers obtained in each analysis are given— 
beginning with those summarised in Table VIII. of the paper—in which the pressure 
of the gases at explosion was observed. The first column gives the reference number. 
In the three next columns the percentage composition of the gas is given, as deter¬ 
mined by mixture or analysis previous to each experiment. The next two columns 
give the pressure (P) and the temperature (T) of the gases just before the spark was 
passed. In the seventh and succeeding columns are given the volumes reduced to 
cubic centimetres at 0° C. and 760 millims. before the explosion (V 0 ), after the 
explosion (V*), after absorption with potash (V„), after addition of excess of oxygen 
(V'o), after explosion (V' e ), and lastly after absorption with potash (V'„).
