=TRANSCRIBER’S NOTE= Italic text is denoted by _underscores_. Bold text is denoted by =equal signs=. Obvious punctuation errors have been corrected after careful comparison with other occurrences within the text and consultation of external sources. Some hyphens in words have been silently removed, some added, when a predominant preference was found in the original book. Pg 19: ‘too feet higher’ replaced by ‘two feet higher’.
