Several unusual characters are used in this book, notably scribal abbreviations (e.g. ?, ?, ?) in Appendix II. If these are being displayed as empty squares, try using a different font to view the book. If changing font does not correct the problem, the reader should consult the text file version. If the characters are not properly displayed in the text file version, the reader should consult the original page images noted above.

A transcriber's note at the end of the book provides details about the changes that were made and includes a list of the illustrations.
