Publisher's Note 



F 



OR bibliographical reasons, Professor Folke Skoog, chairman of the 

 committee responsible for this book, has been designated editor. 

 Listing volumes of essays written under separate authorship presents 

 problems to bibliographers which do not easily lend themselves to prac- 

 tical solution. The Press, therefore, feels that scholars will be grateful for 

 a simple entry under which this book may appear in files, catalogues, 

 and bibliographies.
