Casanova died in 1798, but nothing was heard of the Memoirs (which the Prince de Ligne, in his own Memoirs, tells us that Casanova had read to him, and in which he found 'du dyamatique, de la rapidite, du comique, de la philosophie, des choses neuves, sublimes, inimitables meme') until the year 1820, when a certain Carlo Angiolini brought to the publishing house of Brockhaus, in Leipzig, a manuscript entitled Histoire de ma vie jusqu a l'an 1797, in the handwriting of Casanova. This manuscript, which I have examined at Leipzig, is written on foolscap paper, rather rough and yellow; it is written on both sides of the page, and in sheets or quires; here and there the paging shows that some pages have been omitted, and in their place are smaller sheets of thinner and whiter paper, all in Casanova's handsome, unmistakable handwriting. The manuscript is done up in twelve bundles, corresponding with the twelve volumes of the original edition; and only in one place is there a gap. The fourth and fifth chapters of the twelfth volume are missing, as the editor of the original edition points out, adding: 'It is not probable that these two chapters have been withdrawn from the manuscript of Casanova by a strange hand; everything leads us to believe that the author himself suppressed them, in the intention, no doubt, of re-writing them, but without having found time to do so.' The manuscript ends abruptly with the year 1774, and not with the year 1797, as the title would lead us to suppose.
