Octavo, three volumes, [vi], 244 pages; [x], 246 pages plus 20 plates; and [xii], 244 pages plus 22 plates.
Papered boards; the first volume has a tiny light bump to the leading edge, and a bookseller's inkstamp in the bottom corner of the front free endpaper; essentially, a fine set with the dustwrappers.
A note printed on the verso of the contents leaf in each volume states that it has been reprinted from the 'first edition in which there were a number of errors. These have been corrected where possible, otherwise they have been marked with an asterisk and listed' on a nominated page. [3 items].
