Illustrations in this eBook have been positioned between paragraphs and outside quotations. In versions of this eBook that support hyperlinks, the page references in the List of Illustrations lead to the corresponding illustrations. Illustrations without captions have had a description added, this is denoted with parentheses. The index was not checked for proper alphabetization or correct page references. Obvious typographical errors and punctuation errors have been corrected after careful comparison with other occurrences within the text and consultation of external sources. Otherwise misspellings in the text, and inconsistent or archaic usage, have been retained. Some hyphens in words have been silently removed, some added, when a predominant preference was found in the original book.
