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

Simple typographical errors were corrected; unbalanced quotation marks were remedied when the change was obvious, and otherwise left unbalanced.

Footnotes, originally at the bottoms of pages, have been collected, renumbered, and moved to precede the Index.

The index was not checked for proper alphabetization or correct page references. The link for one incorrect reference was changed and no link was attempted for another incorrect reference.
