The text of this e-book has mostly been preserved in its original form. One spelling error was corrected (considertion → consideration) and a few missing full stops inserted, but inconsistent hyphenation was left unchanged. Italic text is denoted by _underscores_. Superscripted text is indicated by a preceding caret mark, e.g. 2^{n} and subscripted text by a downward arrow, e.g. A↓{2}. Footnotes have been numbered and positioned below the relevant paragraphs.
