Obvious typographical errors have been silently corrected. Variations
in hyphenation, accents, spelling and punctuation remain unchanged.
The book contains a number of decorative borders and separators. These
have been ignored.
Anchors for footnotes 373, 379, 383, 391, 392, 394, 404, and 406 were
missing and have been added in appropriate places. The footnotes are
located at the end of the book.
The images in Arabic are of poor quality so the transcriptions should
be treated with caution.
The use of parentheses, especially in the footnotes, is rather wayward
and they have been paired wherever possible.
Italics are represented thus _italic_, however this marking indicates
letter-spacing in Latin and Greek passages. Bold is represented thus
=bold=.
