Notes with marginal arc and quadrant diagrams (untranscribed)
Mirror-script prose beside small curved diagrams in the right margin
This leaf is filled with Leonardo's right-to-left mirror script, interrupted along the right margin by small diagrams: a quarter-circle sector ruled with fine radiating lines and concentric arcs near the top, and two isolated curved arcs lower down. The writing was not transcribed for this edition, so the specific subject of the notes cannot be determined from the image; the marginal figures are geometric curved constructions. Further untranscribed text is present across the whole sheet.

Marginal quadrant and arc diagrams
Along the right edge of the sheet sit three small geometric figures: an upper quarter-circle sector ruled with fine radiating lines and one or two concentric arcs, and, lower down, two separate curved arcs, one ending in a small hook near a point. They are drawn in the same brown ink as the surrounding text. The accompanying writing is untranscribed and its subject is not identified here.
