The Velocities of Flame in Mixtures of Methane and Air. A. Parker and A. V. Rhead. “ Journ. Chem. Soc.,” Sept., p. 2150; 4 fig. (Conclusions are that the propagation of flame generally occurs in three dis- tinct periods when fired from an open to a closed end of a tube, in the first of which it travels with a con- stant and uniform velocity. The second period con- sists of vibratory movements and a sudden increase in velocity. In the third period the rate again falls to a uniform value. In tubes of given diameter the initial velocity varies with the material of the tube, being less in tubes possessing a high conductivity of heat. The maximum initial velocity is possessed by a mix- ture containing 10 per cent, of methane, the rate of propagation of which is 70 cm. per second. The initial velocity then falls with change of methane content, moving towards zero at 4*5 and 13*1 per cent. The effect of a bend in the explosion tube varies con- siderably with the nature of the bend and the per- centage composition of the mixture.) XYI.—Coal Dust. The Explosibility of Grain Dusts. D. J.
