Transcriber’s Notes
Reading edition
Retained publication information from the printed edition: this eBook is public-domain in the country of publication.
In the text versions only, text in italics is delimited by _underscores_.
Silently corrected a few typos.
Tweaked the order of the Table of Contents to match the text.
Incorporated the “erratum” (from an inserted slip) into the text. The erroneous Step 3 replicated Step 2.
Inserted references to unreferenced endnotes at apparently-appropriate places.
