Footnotes have been renumbered and moved to the end of paragraphs.

All references to footnote numbers (i.e. page and note number) are followed by the footnote number used here in braces e.g. {386}.

Some formatting and punctuation in citations and the index have been standardized.

Variant spelling, inconsistent hyphenation and inconsistent spelling of people’s names are retained, as are inconsistent punctuation after roman numerals (e.g. “i.” and “i” both occur) and inconsistent use of italics, however a few palpable printing errors have been corrected.
