MESSRS. NEUMANN and Aivazov direct attention1 to the negative temperature coefficient of the combustion of hydrocarbon mixtures under certain conditions; this phenomenon, which has also been referred to by Pease2 and by Beatty and Edgar3, seems well established.

The step A B is the normal process whereby the hydrocarbon is oxidised to aldehyde.
