X PREFACE 



organizers to know that these official bodies considered this First lUB/ 

 lUBS Joint Symposium worthy of support, and mention should be made 

 of the National Science Foundation which supported so many of our 

 US. participants; furthermore, in this connection the work done on our 

 behalf by Dr. Elmer Stotz, the treasurer of lUB, should not be forgotten. 



The organizers hope that this Symposium will be the forerunner of a 

 long line of similar international symposia based on fruitful co-operation 

 between biochemists and biologists from all nations. 



The organizers are most grateful to the Institute of Physics, University 

 of Stockholm, for their generosity in putting their attractive new lecture 

 theatre at the disposal of the Symposium. 



In preparing the proceedings for the press the organizers have been 

 greatly helped by Miss J. T. Peel, who transcribed the recorded dis- 

 cussions, and by Mr. D. J. Howells, who prepared the subject index.
