The Errata following the Preface had already been corrected by the
publisher in the source text used.
Only obvious typographical errors were changed, including a few page
numbers in the index. Unusual or inconsistent spellings were retained.
Footnotes were consecutively numbered through the entire volume and
placed at the ends of chapters.
In the Index of the four note references the two which could be ascribed
to footnotes on those pages had those footnote numbers inserted.
