In the text, the metrical ictus is indicated by stress marks; hiatus is indicated by lines drawn between words.

I have chosen to preserve the line numbering used in the major Teubner edition.

In the notes:
Numbers enclosed in brackets refer to the chapters and sections of chapters in my booklet mentioned above (‘Introduction to Latin Textual Emendation,’ Macmillan, London, 1896), which I. Waltzing translated into French (Paris, Klincksieck, 1898).

Words beginning with a capital letter stand at the beginning of verses.

The following must be observed when reading the Palimpsest (A): single dots indicate single letters that cannot be read at all; a dot placed under a letter indicates that the letter is doubtful; letters that stand inside brackets cannot be read but are restored by conjecture; a straight line indicates that neither the number of letters nor their shapes can be read or conjectured in any way.
