This book owes much of whatever value it may possess to monsieur de Fleurieu's assistance in this respect, and the author thanks him most warmly.
The Flinders papers, of which free use has been made, were presented to the Melbourne Public Library by Professor W.M.Flinders Petrie.

They are described in the bibliography.

The transcripts of family and personal documents were especially valuable.

Although they were not supplied for this book, Professor Flinders Petrie gave them in order that they might be of use to some biographer of his grandfather, and the author begs to thank him, and also Mr.E La Touche Armstrong, the chief librarian, in whose custody they are, and who has given frequent access to them.
The rich stores of manuscripts in the Mitchell Library, Sydney, have been thoroughly examined, with the assistance of Mr.W.H.Ifould, principal librarian, Mr.Hugh Wright, and the staff of that institution.

Help from this quarter was accorded with such grace that one came to think giving trouble was almost like conferring a favour.
All copies of documents from Paris and Caen cited in this book have been made by Madame Robert Helouis.
