Finally, I want to thank the Editorial Office of the Smithsonian Institution 

 for planning and designing this book; the Government Printing Office for their 

 special care in its production; and Mr. Harold E. Hugo for his expert supervision 

 of the color plates. 



A grant from the American Philosophical Society (Johnson Fund), made it 

 possible to conduct research on Jackson in Europe. Acknowledgment is herewith 

 gratefully given.
