quite different theory of metallic conduction. According to his theory, a metalScontains atoms which are in the nature of electrical doublets which will orient themselves parallel to any applied electrical fied. These atoms are assumed to have the power of ejecting electrons in the same direction as the axis of the doublet and hence the conducting process on the basis of this theory consists in a tendency for orientation of the doublets under the action of the applied electromotive force and a conseqtent ejection of electrons from one atom to another in the direction in which the current is known to flow. It seems very doubtful to us whether such a theory can be satisfactorily brought in{o agreement with our experimental results, since it would seem at first sight to be merely an accidental coincidence if the mechanical forces which we apply should produce an'orientation in the right direction and of the right amount to give the pulse of electricity whose magnitude we have calculated on the basis of the other theory and actually found experimentally.
