[Bibliographical Note.—Of this issue there were two editions. The title-page of both was the same (as here on the preceding page).

First Edition (1857).—This issue (which is among the rarer Ruskiniana) contained only a portion of the intended Catalogue: octavo, p. 20. The Preface (“Prefatory”) occupies pp. 3–8; the “Catalogue” pp. 9–20. At the foot of the last page is the imprint “London: Printed by Spottiswoode and Co., New Street Square.” There are no headlines, the pages being numbered centrally. The Catalogue contains notes on 25 pictures, but these are not in all cases the same as the first 25 in ed. 2 (see below). Issued stitched and without wrappers.

Second Edition (1857).—Of this edition (limited to 100 copies) the collation is: octavo, pp. ii. +50. A half-title—“Catalogue of the Turner Sketches in the National Gallery, Part I.,” with blank reverse, occupies pp. i.-ii.; title-page, with blank reverse, pp. 1-2; “Prefatory,” pp. 3–49; the last page is blank, but for the imprint in the centre— “London: Printed by Spottiswoode and Co., New Street Square.” No headlines, as before: issued stitched, without wrappers.

Variations between the two Editions.—No. “8. On the Rhine” in ed. 1 becomes No. 11 in ed. 2 (with the words “The same subject, nearer” added after the title); No. 8 being replaced in ed. 2 by “Coblentz, with the Bridge over the Moselle”—a drawing which was not described in ed. 1; while No. 11 in ed. I was discarded in ed. 2.
