On folio 33 verso, the title original Greek: "ἰωάννου γραμματικοῦ ἀλεξανδρέως καὶ σχολαστικοῦ τοῦ φιλοπόνου εἰς τὰ πρῶτα τῶν προτέρων ἀναλυτικῶν ἀριστοτέλους σχολικαὶ ἀποσημειώσεις ἐκ τῶν συνουσιῶν ἀμμωνίου τοῦ ἑρμείου τῶν εἰς τὰ τρία τὸ πρῶτον" reads: "School notes of John the Grammarian of Alexandria and the Scholastic Philoponus on the first part of Aristotle’s Prior Analytics A foundational work by Aristotle on deductive reasoning and the syllogism., from the lectures of Ammonius Ammonius Hermiae, a 5th-century philosopher who taught in Alexandria., son of Hermias, the first of three parts." — it begins with the words "It has already been said by us" and ends on folio 35 verso at the words "part with the whole" (corresponding to pages 1.5 to 9.20 of the printed edition).

On folios 36 recto to 37 verso, there are geometrical scholia scholia are explanatory notes written in the margins of ancient or medieval manuscripts. (on folio 36 verso, these are attributed "to Psellus" Michael Psellus was a prominent 11th-century Byzantine polymath.; the rubricator The scribe responsible for adding red ink headings or notes. has added in the margin: "Here are the required theorems of the geometer Euclid, which Aristotle mentions here and there in his treatise on logical demonstration.").

On folio 38 recto begins: "The first book of Aristotle's Prior Analytics concerning the three figures of the syllogism" original Greek: "Ἀριστοτέλους περὶ τῶν τριῶν τοῦ συλλογισμοῦ σχημάτων ἀναλυτικῶν προτέρων πρῶτον" with interlinear notes and marginal notes. The marginal notes, which are numbered, belong entirely to Philoponus up to folio 47 recto (after folio 42, two leaves seem to have fallen out).

From folios 47 verso to 64 recto, the words of Aristotle are equipped with a double commentary by Philoponus and Magentenus Leo Magentinus, a 13th-century commentator., arranged such that the latter occupies the narrow outer margin (on the right side for recto folios and on the left side for verso folios), while the former occupies the remaining parts of the margin.

On folios 65 verso to 67 recto, the notes are again by Philoponus alone. On folio 67 verso, alongside his commentary in the outer margin, a note by Ammonius is found (compare volume 4, part 6, page 12 and following).

On folio 68 verso, the title reads: "Notes of John of Alexandria, also known as Philoponus, from the lectures of Ammonius, on the first book of Aristotle’s Prior Analytics, the first of the three parts: — the beginning of the mixtures of different materials in the three figures." original Greek: "ἰωάννου ἀλεξανδρέως τοῦ φιλοπόνου ἐκ τῶν τοῦ ἀμμωνίου συνουσιῶν εἰς τὸ πρῶτον τῶν προτέρων ἀναλυτικῶν ἀριστοτέλους τῶν εἰς τὰ τρία τὸ πρῶτον: — ἀρχὴ τῶν μίξεων τῶν ἐν τοῖς τρισὶ σχήμασι διαφόρων ὑλῶν." But from folio 72 recto onward, the notes of others begin to predominate ¹).

On folio 124 verso, the title reads: "Explanation of John the Grammarian and Alexandrian, Philoponus, on the analysis of syllogisms, third section" original Greek: "ἐξήγησις ἰωάννου γραμματικοῦ καὶ ἀλεξανδρέως τοῦ φιλοπόνου εἰς τὸ περὶ ἀνάλυσεως συλλογισμῶν, τρίτον τμῆμα" — it ends on folio 144 verso ²) at the words "we have already said" (page 386.6).
