[Bibliographical Note.—Of this pamphlet there have been fourteen separate editions, and the bibliography is somewhat complicated.

Summary.—The following brief summary may be acceptable to those who do not desire the further minutiæ. Edition No. 1 was incomplete, so far as Ruskin's Notes were concerned, and contained an appendix by Mr. Huish, not here reprinted. No. 2 was a reprint of No. 1. No. 8 included the Epilogue in an unfinished form, and in it were included as addenda, ‘Further Illustrative Studies’ (see pp. 473–474). Nos. 4, 5, and 6 were reprints of No. 3. In No. 7 the Epilogue was revised; Notes by the Rev. YV. Kingsley, with occasional remarks by Mr. Ruskin, were added as an appendix (pp. 533–536), Mr. Huish's appendix being now omitted. No. 8 was a reprint of No. 7. No. 9 was enlarged by the inclusion of Part II., being Mr. Ruskin's Notes on a selection of his own drawings. In No. 10 the text was revised. Nos. 11 and 12 were reprints of No. 10. The Illustrated Edition, No. 13, was a reprint of Nos. 10–12, together with Mr. Huish's appendix (and an additional map) from Nos. 1–6. No. 14, issued in 1900, was, so far as it went, a reprint of Nos. 10–12, but with numerous omissions.
