Transcriber's Note: each of Green's footnotes has been placed after
the paragraph to which it refers, and renumbered accordingly.
The footnotes added by R.L. Nettleship are treated the same way,
remain in the square brackets with which he distinguished them,
and are marked 'RLN'. The transcriber has added a few footnotes,
mainly explaining Greek words in the text. These are also in square
brackets, marked 'Tr'.
