Punctuation and spelling were made consistent when a predominant preference was found in this book; otherwise they were not changed. This book was published in 1844, so some words may have been spelled differently than they are now.

Simple typographical errors were corrected; occasional unbalanced quotation marks retained.

Ambiguous hyphens at the ends of lines were retained; occurrences of inconsistent hyphenation have not been changed.

Most of the Errata on the last page of the book have been corrected within the text; the change to page 163 was not made because it was ambiguous.

Page 132: “Hopson’s choice” probably is a misprint for “Hobson’s choice”.

Page 153: “smooth and melodies” was printed that way.

Page 168: “De gustibus non disputandum” is a misquotation for “De gustibus non est disputandum”.
