The publication of Taylor’s theory of the catalytic surface renders it opportune to describe certain hitherto unpublished experiments which accord excellently with the view which he has advanced. Therefore, we give a brief outline of the work in question and adduce other experimental evidence which points to the strong probability that the acting (nickel) atom is, at the moment when catalytic change occurs, not merely held to the rest of the solid surfaces by a single constraint, but can be actually, momentarily, detached therefrom; in physico-chemical parlance, it has become for the time being a gaseous (nickel) atom.
