The text includes a large number of marginal notes that are printed in
small font and are sometimes unclear. They have been converted into
footnotes or (if they comprise general descriptions of a passage) into
sidenotes. A footnote may refer to the following, rather than
preceding, word or phrase. If so the footnote anchor has been
positioned accordingly.
Many of the paragraphs are numbered according to a complex scheme.
Only on one page are they indented. While the numbering has been
retained the indenting has been removed.
Apparent typographical errors, and inconsistencies in hyphenation,
have been corrected. Superscripts and one word in spaced-out text have
been rendered in ordinary font. Small capitals have been converted to
ordinary capitals. Italics are indicated by _underscores_.
Greek accents are often unclear and (apart from rough-breathing marks)
have been omitted.
The error noted at the end of the text has been incorporated.
