PREFACE 



In this book we have attempted to give a brief account 

 of the biochemistry and the physiology of photo- 

 synthesis in such a way as to provide an introduction 

 to present researches in this field. 



We are grateful to many of our colleagues for their 

 help; in particular we are indebted to Professor G. E. 

 Briggs, F.R.S., whose teaching has greatly contributed 

 to Chapters 2 and 4, and who has allowed us to select 

 freely from his unpublished lecture notes, and to Pro- 

 fessor E. J. Maskell, F.R.S., who kindly criticized the 

 manuscript. We wish to thank Miss C. Lambert who 

 prepared the drawings.
