     Discharge tube with steel electrodes both cooled by incoming gas, was used.  CH₄, both pure and distilled with H₂, was drawn through the tube.  C₂H₂ was condensed with liquid air.  Most of the CH₄ was converted to C₂H₂ and H₂.  The influence of gas velocity, tube loading, and pressure are shown in tables.  A pressure of 50 mm., gas velocity of 370 l./hr., and 1.3 kv.-a. power input gave 8.5% C₂H₂ in the exit gas, at an electric energy consumption of 31 kv.-a./m.³ C₂H₂.
