- Punctuation: the semicolon marks the main pause, the medial point lesser pauses.
- Omissions, supplied by an eighth-century hand, are indicated by in the text answered by before the insertion in the lower margin (p. 19), or by signes de renvoi.
- Abbreviations: b; (and b:), q; (and q:) = bus, que; aū = autem; ƀ = ber; ec̄ = ecce; ē and ·ē· = est; fr̄s = fratres; = men; = non; ni = nostri; os = omnis and omnes; ꝑ, = per, prae; q = quod; ꞇ̄ = ter; the abbreviation-stroke is a horizontal or vertical flourish.
- Spelling, unusually barbarous, shows confusion of c and g, e and i, o and u, d for t, ci for ti, and ss for s.
- Script is a small, distinct pre-Caroline minuscule considered typical of Breisgau, and for the most part probably in the hand of Liutfrit, the scribe of several St. Gall charters (e.g., the charter of A.D. 754): open ɑ is the rule; the head of g is closed; i-longa is frequent initially; majuscule N occurs here and there at the beginning of words; the top of ꞇ forms a loop to the left; the ro ligature is noteworthy, as it ends in a dot above the o; Ɛ is used for hard ti; the script on part of p. 173 is in manifest imitation of Insular majuscule, even to the wedge-shaped ascenders (see plate).
- Running titles on some openings, in small uncial preceded and followed by lines and points.
- Colophons in black uncial.
- Headings in red or black bold uncial, occasionally daubed with red or yellow.
- Initials in bold black or filled with red or yellow.
- Ink dark brown.
Partly palimpsest, secondary script (for the primary script containing 153 -160, 163-170, 177, 178 are ter scripti; their intermediate script showing traces of an unidentified theological text is so similar to the present uppermost script that it must have been written in the same centre only a short time before; pp. 89 f., 99 f., 109 f. ,119 f., 127 f., 131 f., 135 f., 141 f., 145 f., 149 f., 179 f. have no lower script).' Divinae Institutiones in uncial saec. V, see next item; pp.
- No punctuation, a blank space of 2 or more letters marking sense-pauses and setting off.
- Abbreviations seen are B·, Ɋ· and the normal forms of Nomina Sacra; but ꝹI and ꝹO also occur written out; sanctus is abbreviated (SC̄S) only when accompanied by SP̄S. Omission of M and N occurs at line-end and is marked by a short horizontal over and after the vowel. A larger letter begins most pages - a sign of antiquity. Ink left yellowish traces.
- Script is an excellent early uncial; the eye of is open; N is broad; various ligatures occur at line-ends.
Palimpsest, primary script (for the secondary script, containing Gregory's Dialogues, etc., and, in parts of the manuscript, for the intermediate script containing an unidentified theological text, both in pre-Caroline minuscule saec. VIII, see preceding item).
