Punctuation, hyphenation, and spelling were made consistent when a
predominant preference was found in the original book; otherwise they
were not changed.
Spelling and accents in Italian words follow the way the original book
was printed.
Simple typographical errors were corrected; unbalanced quotation
marks were remedied when the change was obvious, but several remain
unbalanced.
