Transcriber's Notes
Punctuation and spelling were made consistent when a predominant preference was found in this book; otherwise they were not changed.
Simple typographical errors were corrected; occasional unbalanced quotation marks retained.
Inconsistent hyphenation, e.g., "co-operation" and "cooperation", has been retained unless one form predominated.
Ambiguous hyphens at the ends of lines were retained.
Page 174: "and sheet force of will" is misprint for "sheer".
Page 249: Several colons would be semi-colons in modern practice.
Index was not well-alphabetized; corrected here. Diacriticals and ligatures have been alphabetized as plain letters.
