We have already indicated the undesirability of any general theory to explain promotor action in the case of catalyst activity, preferring to investigate each specific instance. In the cases previously studied (Parts VIII and IX) the increased activity in presence of the promotor has been ascribed to causes essentially chemical rather than physical; in the examples now described, namely, alumina and certain other metallic oxides, it will be shown that a simple mechanical explanation, the development of greater surface, is most in harmony with the observed facts.
