✦ Synopsis

The temperatures in the stream of flases emitted from a ~llulosic solid subjected to thernml radiation have been measured, and the effects of various factors, including the size of the area heated by the radiation and turbulence, on the likelihood of the ignition of the gases have been. examined. The occurrence of turbulence in the stream of gases, even though it does not affect the temperature of the solid or the gases at their point of emission, appears to be necessary for flame to appear. External draughts, by producing turbulence, reduce the minimum intensity of radiation at which materials ignite, but if i(jnition occurs in the absence of an external drm~jht, the imposition of one i~ the range of these experiments, does not a~ect ~he ignition time.
