PREFACE vii 



Annette Van der Schalie and Ursula Freimarck together read and typed the 

 entire manuscript. 



Finally I wish to express my deep appreciation to members of my family, 

 especially my wife, for not only helping in the preparation of the glossary and 

 index but more particularly for their kind understanding during the inception 

 and gestation of this book.
