Finally, it must be remembered that when the History was published in 1758, Lord Orrery was still living. If the work were a forgery, why did not Lord Orrery expose it? Nothing would have pleased him more. He had read the manuscript referred to in the Correspondence. He had carried it to Oxford and given it to King, at Swift's request. He knew all about it, and he said nothing. These considerations, both negative and positive, lead us to the final conclusion that the History published in 1758 is practically the History referred to in Swift's Correspondence, and therefore the authentic work of Swift himself. We say practically, because there are some differences between it and the text published here. The differences have been recorded from a comparison between Lucas's version and the transcript of a manuscript discovered in Dublin in 1857, and made by Mr. Percy Fitzgerald. Mr. Fitzgerald found that this manuscript contained many corrections in Swift's own handwriting. At the time he came across it the manuscript was in the possession of two old ladies named Greene, grand-daughters of Mrs. Whiteway, and grand-nieces of Swift himself. On the title-page there was the following note: "This is the originall manuscript of the History, corrected by me, and given into the custody of Mrs. Martha Whiteway by me Jonathan Swift, June 15, 1737. seven. "I send a fair copy of this History by the Earl of Orrery to be printed in England. "JONATH. SWIFT." Mr. Fitzgerald was permitted to make a collation of this manuscript, and his collation he sent to the late John Forster. It is now in the Victoria and Albert Museum, South Kensington.[2] [Footnote 2: I regret that I have been unable to trace the existence of this manuscript of Swift's "History." Mr. Fitzgerald himself has no recollection of having made the collation. "Forty-five years ago," he writes, "is a long time to look back to," and he cannot recall the fact.] If this manuscript be what, on the face of it, it claims to be, then the question of authenticity is for ever settled. As we have no doubt on this point, the corrections and variations between this manuscript, as collated by Mr. Percy Fitzgerald and the Lucas version, have been noted in the present edition.
