Transcriber’s notes:

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. To help readers navigate the book more easily, hyperlinks have been added to footnotes, the table of contents, and internal cross-references. Footnotes have been numbered and moved to the end of the book.

The text contains tables and symbols that might not display faithfully on small reading devices.

The cover image of the book was created by the transcriber and is placed in the public domain.
