Editors' Preface 



The International Union of Biochemistry asked us to act as Editors of this 

 English-French-German Edition of the entire Proceedings of the Symposium, 

 which is being pubHshed in parallel with a Russian Edition. The Committee 

 acting for the Academy of Sciences of the U.S.S.R. as Editors of the latter have 

 supplied us with texts, which are here published with minor editorial changes 

 for the sake of imiformity. Texts received in Russian have been translated into 

 Enghsh by Mrs. Aim Synge, and these are indicated by asterisks in the Contents 

 List. 



Some of the contributions to the Symposium were preprinted as uncorrected 

 proofs in Enghsh, French and German for the use of participants in the Sym- 

 posiimi. As these contributions were bovind, they could be confused with the 

 present definitive publication. Unfortunately, they received notice in Chemical 

 Abstracts (52, 1331, 1958). 



A multilingual publication presents special difficulties in the transHteration 

 of Russian names. We have followed as far as possible the system used in 

 Chemical Abstracts, but this could not be done rigorously, especially in the 

 French and German papers. To restore non-Russian proper names from Russian 

 texts to their original spellings demands superhuman qualities, and mistakes are 

 certainly present. For these and other errors we apologize. 



Abbreviations for periodicals are as far as possible those used in the World 

 List of Scientific Periodicals published in the Years 1 900-1 950 (Butterworths 

 Scientific Pubhcations, London, 1952) or in Chemical Abstracts. Other abbre- 

 viations follow in general the practice of the Biochemical Journal. The Indexes 

 have been compiled by Mr. W. Hill.
