I have from time to time cited from earlier editions readings of manuscripts which I have not collated. To make it clear that I have not personally verified these readings, I have added in parentheses after the citation the name of the editor whose report I am using. Professor R. J. Tarrant has inspected some nine manuscripts to see what readings they offered in some particularly vexed portions of the poems; I have similarly indicated when I am obliged to him for information on a manuscript. The _excerpta Scaligeri_ mentioned at xiii 27 I know of through Heinsius' notes as printed in Burman's edition; according to M. D. Reeve (_RhM_ CXVII [1974] 163), the original excerpts are still extant in Diez 8° 2560, a copy of the _editio Gryphiana_ of 1546. Reeve also gives identifications of certain of Heinsius' manuscripts; when citing Heinsius' codices, I give the modern name when the manuscript has been identified and is still extant. The greater number of the manuscripts dealt with have been corrected, some heavily. In my apparatus _B1_ means "the original hand in _B_" and _B2_ means "a correcting hand in B". _B2ul_ indicates that the reading of _B2_ is clearly marked as a variant reading. _B2gl_ indicates that the entry is marked in the manuscript as a gloss; _B2(gl)_ indicates a gloss not marked as such. I have reported glosses where they contribute to the understanding of a textual problem. If different correctors have been at work in different passages, both are called _B2_. If a later hand has made a correction after _B2_, the later hand is called _B3_. When I place _B1_ in an entry but do not report _B2_, it can be assumed that _B2_ has the lemma as its reading. Sometimes a corrector has altered the original text so much (without however erasing it entirely) that only the altered reading can be made out. In such cases I have used the siglum _B2c_. Where a corrector has inserted or altered only certain letters of a word, I have indicated this in the HTML version of this edition by underlining the letters involved. In the Text version, these letters are capitalized. Where the correction is apparently by the original scribe, _Bac_ indicates the original reading, and _Bpc_ the correction. The asterisk is used to indicate illegible letters, and the solidus (/) erasures. When reporting variants, I have tried to indicate the spellings actually found in the manuscripts, but since mediaeval spellings do not in themselves constitute variant readings, they have not usually been reported when the text is not otherwise disturbed. I have been more generous with proper names, but have often excluded confusions of _ae_, _oe_, and _e_, of _i_ and _y_, of _ph_ and _f_, of _c_ and _t_, the doubling of consonants, and the loss or addition of the aspirate.
