Abstract
THE following facts relating to the travel of name, initiated by an electric spark, through a homogeneous inflammable gaseous mixture have been established: (1) Flame photographs show that the flame front during the early stages of travel is of low luminosity, but later it builds up a high luminosity indicating a high instantaneous pressure and temperature. (2) Turbulent motion of the inflammable mixture before combustion has no influence upon the rate of travel of the flame front in the early stages, but has a marked influence upon this in the later stages1.
