No book or chapter headings. Abjad numerals overlined. Diagrams with red lines and black geometrical points. Codex in satisfactory condition; damage by insects throughout, minor water damage in the margins and in the text area of f. 57, stains (e.g., 11v–12r); margins and folds sometimes reinforced with tape, affecting the readability.
