Transcriber's Notes:

  Underscores "_" before and after a word or phrase indicate _italics_
    in the original text.
  A single underscore designates a subscript.
  Equal signs "=" before and after a word or phrase indicate =bold=
    in the original text.
  Carat symbol "^" designates a superscript.
  Small capitals have been converted to SOLID capitals.
  Illustrations have been moved so they do not break up paragraphs.
  Typographical errors have been silently corrected but other variations
    in spelling and punctuation remain unaltered.
