In preparing for the press and printing this enlarged edition of Mr. Horne Tooke's Diversions of Purley, an undertaking assigned to me by the Publisher, on his becoming possessed, by assignment from the Author's representatives, of the copy containing his last corrections and additions, it has been my endeavour in the first place to remove the many inaccuracies of the former Edition, by a collation of the citations in which the work abounds with the originals, so far as they were within my reach; and, next, to incorporate in it, as well as I was able, the new materials, in such a manner as should not interfere with the integrity of the former text. As these additions, written in the Author's interleaved copy, and which, especially in the Second Part, are very abundant, were wholly without any references connecting them with the text, and sometimes written at a distance of several pages from the passages to which they seemed to belong, I must beg the Reader's indulgence if I should at any time have failed in this part of my task; reminding him that, all the new matter being distinguished by brackets, [], he may use his own judgement as to its relation to the text.
