more inflammable mixtures have the higher ratios, and the 

 variation of the efficiency of explosion with percentage of 

 gas appears to be in a regular manner. In fig. 2 the ratios 

 in Table II. are set down graphically, and the curves are 

 soon to have the same shape throughout, I. being for 

 Glasgow gas, II. for Oldham gas.
