He found further that the change of the metallic contact resistance when acted upon by electric waves, is a function of the atomic weight. These phenomena led to a new theory of metallic coherers. Before these discoveries it was assumed that the particles of the two metallic pieces in contact are, as it were, fused together, so that the resistance decreases. But the increasing resistance appearing for some elements, led to the theory that the electric forces in the waves produced a peculiar molecular action or a re-arrangement of the molecules, which may either increase or decrease the contact resistance. --_Pioneer_,--16-1-1916. HINDU UNIVERSITY ADDRESS The foundation of the Hindu University was laid by Lord Hardinge on the 4th February 1916. "Many striking addresses were delivered on the occasion. Professor J.C. Bose in his masterly address went to the root of the matter and pointed in an inspiring manner what should be done to make the Hindu University worthy of its name. He deprecated a repetition of the Universities of the West." He said:-- In tracing the characteristic phenomenon of life from simple beginnings in that vast region which may be called unvoiced, as exemplified in the world of plants, to its highest expression in the animal kingdom, one is repeatedly struck by the one dominant fact that in order to maintain an organism at the height of its efficiency something more than a mechanical perfection of its structure is necessary. Every living organism, in order to maintain its life and growth, must be in free communion with all the forces of the Universe about it. STIMULUS WITHIN AND WITHOUT Further, it must not only constantly receive stimulus from without, but must also give out something from within, and the healthy life of the organism will depend on these two fold activities of inflow and outflow. When there is any interference with these activities, then morbid symptoms appear, which ultimately must end in disaster and death. This is equally true of the intellectual life of a Nation. When through narrow conceit a Nation regards itself self-sufficient and cuts itself from the stimulus of the outside world, then intellectual decay must inevitably follow. SPECIAL FUNCTION OF A NATION So far as regards the receptive function. Then there is another function in the intellectual life of a Nation, that of spontaneous outflow, that giving out of its life by which the world is enriched. When the Nation has lost this power, when it merely receives, but cannot give out, then its healthy life is over, and it sinks into a degenerate existence which is purely parasitic.
