Punctuation has been standardised and simple typographical errors have been repaired. Hyphenation, quotation mark usage, and obsolete/variant spelling (including variant spellings of proper nouns) have been preserved as printed. In the original book, the page numbering goes xiii, blank, unnumbered, 18. This is a printer’s error: no pages are missing.
