On 1859 Lascelles Wraxall translate Memoirs of Robert-Houdin. On 1868 Robert-Houdim made new edition. I compare "Confidences d'un prestidigitateur" on 1995 and english version. There are at least one new chapter - XVII.
For me interesting - is it was new translation on English full version of Memoirs or English langusge Magic World did not find new chapter?
