In a previous paper on “The Adsorption of Hydrogen on the Surface of an Electrodeless Discharge Tube,” experiments were described tracing the growth of a monomolecular layer. In the present paper these and further experiments are used to determine some of the conditions under which the constituents of the layer become enabled to leave it. It is first necessary to decide what distinctions can be drawn between the processes involved without depending on the unknown mechanism they may cover; hydrogen in this is peculiar, for while any gas-solid interface must strictly present a complex of several simultaneous processes, often including solution and chemical reaction, hydrogen alone allows us to isolate almost completely each in turn of the two following types of energy exchange between the phases.
