Punctuation, hyphenation, and spelling were made consistent when a predominant preference was found in this book; otherwise they were not changed.

Simple typographical errors were corrected; occasional unbalanced quotation marks retained.

Ambiguous hyphens at the ends of lines were retained.

Index not systematically checked for proper alphabetization or correct page references, but the following discrepancies were found: the index reference to “D’Orsay, Count, 132” was misprinted as “133” and has been changed here; “Saxe-Coburg-Gotha, Duke of” appears in the index, but the name does not appear anywhere else; and the index reference to “Villa Garbarius” is printed as “Villa Garbarino” on page 90.
