Punctuation, hyphenation, and spelling were made consistent when a predominant preference was found in this book; otherwise they were not changed. Accent marks in non-English words were not changed.

Simple typographical errors were corrected; occasional unbalanced single and double quotation marks retained unless the correction was unambiguous.

Ambiguous hyphens at the ends of lines were retained.

Index not systematically checked for proper alphabetization or correct page references; many entries in the Index are spelled or accented differently than on the pages they reference.

Page 118: “oppose the fact” was printed as “oppose to fact”; changed here.
