       Ratio CO : H₂ burned in a mixture of the gases containing O₂ at the surface of Cu, and Cu containing, admixed with it, varying quantities of Pd has been measured.  A real specific promoting effect was observed and the addition of Pd to Cu definitely increased the ratio CO : H₂.  The promoting action of Pd on Cu is ascribed to a peculiarity of the Cu-Pd interface.  The anamalous activities of molecules at interfacial boundaries and points of discontinuity are cited in favor of this view.
