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

Words spelled differently in quoted passages than in the author’s own text have not been changed.

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

Chapter II’s footnotes originally skipped number “3”. The omission is not apparent in this eBook, in which all footnotes are in a single ascending sequence.

Ambiguous hyphens at the ends of lines were retained.

For consistency, all occurrences of “bow-foremost” and “stern-foremost” are hyphenated in this eBook.

Index not checked for proper alphabetization or correct page references.
