The “normal” propagation of flame in gaseous mixtures

In this paper a preliminary attempt has been made to trace the relationships, where they exist, between the speeds of flame in mixtures of air with the constituents of the common industrial gases, hydrogen, carbon monoxide, methane (and other paraffin hydrocarbons), ethylene, and acetylene, inflamed under different conditions. It is hoped to extend these relationships as the results of work now in progress, and also to be able to examine systematically, and in somewhat greater detail, the exceptions to these relationship as they appear.
