Transcriber’s Notes

—Publication information is from the original print copy—this e-text is

public domain in the country of publication.

—Silently corrected palpable typos; left non-standard spellings and

dialect unchanged.

—Split single captions describing multiple images, into multiple

captions.

—In the text versions, delimited italics text in _underscores_ (the HTML

version reproduces the font form of the printed book.)
