Transcriber's Notes
1. Minor changes have been made to correct typesetters' errors, and to ensure consistent spelling and punctuation in this etext; otherwise, every effort has been made to remain true to the original book.
2. The sidenotes used in this text were originally published as banners in the page headers, and have been moved to the relevant paragraph for the reader's convenience.
3. The original Table of Contents mistakenly referred to Chapter V. as beginning on page 146; this has been corrected to show that that chapter begins on page 140. Additionally, other minor changes have been made in positioning of page numbers to accommodate positioning of page numbers.
