It was in Dr.
Routh's edition that almost all of Swift's notes first appeared.

In the Preface to the issue of 1823, the learned editor informs us that Swift's notes were taken "from his own copy of the history, which had come into the possession of the first Marquis of Lansdowne." A note in the edition of 1833 corrects a statement made in the previous edition that Swift's copy had been burnt.

It was not Swift's own copy, but a copy containing a transcript of Swift's notes that was burnt.
In the preparation of the present text every available reference has been searched.

Sir Walter Scott's reprint of Swift's "Notes" was sadly inadequate.

Not only did he misquote the references to Burnet's work, but he could not have consulted the Lansdowne copy, since fully a third of the "notes" were altogether ignored by him.
