234 ADDRESS DELIVERED AT 



Zwingli held their famous conference on Consubstantia-

 Ludwig and Fick were at the Anatomical Institute, 

 Waitz lectured on philosophy and anthropology, Hessel 

 expounded crystallography, while my accomplished 

 friend Knoblauch arrived subsequently from Berlin.

 ran an open brook fringed with acacias. Before the
