Punctuation, diacritical and formatting markup have been normalized.

Apparent printer's errors have been retained.

Missing page numbers are attributed to blank pages, unnumbered pages and illustrations moved to match their mention in the original text.

On pages 43 and 191, an alternative diacritic mark was used in the word, "Är-go?n´". Please note that the original diacritic mark, believed to be a short up tack, is unable to be represented in html.
