All the more important variations between the various editions have already been given in footnotes to the text. For the sake of completeness, the remaining variations are here given. A few quite obvious misprints, and some trifling variations in spelling and punctuation, are not, however, enumerated. Nor are the errata noted in ed. 1 (see p. li. above), and again in 1880 ed.

Preface to First Edition, § 4, line 5, ed. 1 omits “as a”; and in line 6, reads “a,—ū,” instead of “—ū.”

Preface to Second Edition, line 17, in the reprint of part of this preface in the 1880 and later eds., the word “have” was inserted between “I” and “found.” § 2, third line from end, 1880 ed. reads “artistic” for “artistical” (and so below, § 6, line 1).

Ch. i. § 4, line 19, small ed. (1890 and later) reads erroneously “perspective” for “prospective.” § 8 (in the omitted passage, see note on p. 41), ed. 1 omits the word “altogether” after “church decoration.”

Ch. ii. § 2, line 18, ed. 1 reads “the force of instances few and familiar”; § 8, line 23, “buttress” not italicised in ed. 1; line 41, “being” omitted in eds. 1 and 2; § 11, line 17, for “their mere weight and strength,” ed. 1 reads “the weight of the one and the strength of the other”;
