Transcriber’s Notes
Reading edition
Retained publication information from the printed edition: this eBook is public-domain in the country of publication.
Added a Table of Contents.
Relocated all image captions to be immediately under the corresponding images, removing redundant references like “preceding page”.
Silently corrected a few palpable typos.
This book was printed mostly in italic, with emphasized text in roman; the eBook reverses those fonts.
In the text versions only, text in roman is delimited by _underscores_.
