In some of these notes―v 1.7–8; 4.5; 5.4; 10.3 (1)―I defend readings of the codex unicus, F (Laurentianus conv. soppr. 627), in others―v 1.2; 7.3; 10.5; 12.3―I support previous conjectures whose merits seem to me not to have been fully appreciated, and in the rest―v 2.2; 2.7; 7.8; 8.2–3 (bis); 8.4; 9.6; 9.9; 9.10; 10. 3 (2); 10.8; cf. 6.2―I put forward new proposals of my own. The base-text and apparatus are those of A. D. Papanikolaou (Teubner, 1973), except for 1.7–8, 4.5, and 5.4, where the text of F is given.
