I owe much to M.Petit Dutaillis for certain kindly observations which I have taken into consideration.

I am also greatly indebted to M.Henri Jadart, Secretary of the Reims Academy; M.E.
Langlois, Professor at the Faculte des Lettres of Lille; M.Camille Bloch, some time archivist of Loiret, M.Noel Charavay, autographic expert, and M.Raoul Bonnet.
M.Pierre Champion, who albeit still young is already known as the author of valuable historical works, has placed the result of his researches at my disposal with a disinterestedness I shall never be able adequately to acknowledge.

He has also carefully read the whole of my work.

M.Jean Brousson has given me the advantage of his perspicacity which far surpasses what one is entitled to expect from one's secretary.
In the century which I have endeavoured to represent in this work, there was a fiend, by name Titivillus.

Every evening this fiend put into a sack all the letters omitted or altered by the copyists during the day.
