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

I have chosen to maintain the line numbering used in the larger Teubner edition.

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

Words starting with a capital letter stand at the beginning of lines.

In describing the readings of the Palimpsest (A), the following should be noted: single dots indicate letters that cannot be read at all; a dot placed under a letter indicates that the letter is doubtful; letters standing within parentheses cannot be read, but are restored by conjecture; a straight line indicates that neither the number of letters nor the shapes can be read or conjectured in any way.
