We come now to the documents directly relating to the _Memoirs_, and among these are several attempts at a preface, in which we see the actual preface coming gradually into form. One is entitled _Casanova au Lecteur_, another _Histoire de mon Existence_, and a third _Preface_. There is also a brief and characteristic _Precis de ma vie_, dated November 17, 1797. Some of these have been printed in _Le Livre_, 1887. But by far the most important manuscript that I discovered, one which, apparently, I am the first to discover, is a manuscript entitled _Extrait du Chapitre 4 et 5_. It is written on paper similar to that on which the _Memoirs_ are written; the pages are numbered 104-148; and though it is described as _Extrait_, it seems to contain, at all events, the greater part of the missing chapters to which I have already referred, Chapters IV. and V. of the last volume of the _Memoirs_. In this manuscript we find Armelline and Scolastica, whose story is interrupted by the abrupt ending of Chapter III.; we find Mariuccia of Vol. VII., Chapter IX., who married a hairdresser; and we find also Jaconine, whom Casanova recognises as his daughter, 'much prettier than Sophia, the daughter of Therese Pompeati, whom I had left at London.'[3] It is curious that this very important manuscript, which supplies the one missing link in the _Memoirs_, should never have been discovered by any of the few people who have had the opportunity of looking over the Dux manuscripts. I am inclined to explain it by the fact that the case in which I found this manuscript contains some papers not relating to Casanova. Probably, those who looked into this case looked no further. I have told Herr Brockhaus of my discovery, and I hope to see Chapters IV. and V. in their places when the long-looked-for edition of the complete text is at length given to the world.
