Inflammability of Mixtures of Methane and Various Gases.

LEPRINCE-RINGUET. (Co~bpte.~ Rendus, clviii, i999.)---The upper and lower limits of inflammability were determined for mixtures containing methane and oxygen in the constant proportions, CH 4 + 202, and also varying amounts of nitrogen, carbon dioxide, and water vapor. The effect of added nitrogen was to lower the upper and raise the lower limit until the two coincided at a point corresponding to the composition : (CH~ + 202) 2o.1 per cent. and N 79.9 per cent. The effect of carbon dioxide was similar, but of different magnitude, o.56 volume of carbon dioxide having an effect approximately equal to that of i volume of nitrogen. The effect of water vapor could also be represented in a similar manner, so that if the mixture, temperature, and humidity are known, all necessary facts as to the inflammability can be deduced from a single diagram.
