viii. INTBODUCTION TO FEENCH EDITION 



I have experienced at the hands of a large number of 

 our ministers, consuls, or consular agents abroad the most 

 cordial reception on repeatedly addressing myself to them 

 in order to obtain the papers or information of which I was 

 in need. It is only right for me to thank them for it, 

 and to acknowledge the trouble that M. Masson has most 

 kindly taken in publishing this book.
