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. Two typographical errors in quoted text on page 37 were
corrected after consulting a copy of the book from which the quotation
was taken.
The illustrations at the ends of chapters I, II, VI, VIII, and X
are simple decorative tailpieces.
