I have before me today a very difficult task and one I feel I shall only very partially be able to fill. It is with considerable difference I approach it at all and am doing so because I feel that the work I and the group of others have been engaged in now for a number of years has reached the stage where it is imperative, for all the soundness of its future work that the very tentative conclusions which I have been forming in regard to the meaning of the phenomena that we are studying, would be submitted to such a gathering as this for expert criticism and advice.
