In this series of lectures dedicated to the memory of Albert D. Lasker, my distinguished predecessors have established such a high order of interest and eminence in their presentations that I am going to be hard put to match their performance alone without outside aid.

If I once in a while attempt to establish my own individuality independently of the dolphins, I am sure that you will forgive me.
I would like to approach this subject from a slightly different viewpoint than that
