PREFACE 



This volume contains the papers and discussion material presented at 

 the Symposium on Haemotin Enzymes. It was held at Canberra between 

 31st August and 4th September, 1959, and was organized by the Australian 

 Academy of Science for the International Union of Biochemistry. 



The Symposium was arranged for the Academy by a Committee com- 

 prising A. H. Ennor, J. E. Falk, R. Lemberg and R. K. Morton (Convener). 

 The Committee is grateful to several organizations, cited in the address by 

 Dr. R. Lemberg, President of the Symposium, for financial and other 

 assistance. 



The titles and addresses of participants are given on pp. xvii-xx. For 

 convenience, titles have been omitted from the scientific communications. 



It is with profound regret that we record the untimely death in October, 

 1960, of Professor Enzo Boeri, one of the distinguished participants in the 

 Symposium. He made many notable contributions to our knowledge of 

 haematin enzymes and he will be remembered with admiration, respect and 

 affection by all who were privileged to know him. 



R. K. Morton
