Circle divided into six sectors with device studies
Geometric division of a circle above two upright mechanical figures
The catalogue records this leaf as invisible before restoration and devoid of writing, though drawings survive. The dominant figure is a large circle with a concentric inner ring, divided by radii into six sectors, one of which is further subdivided. Below it two upright ornate device studies are lightly drawn, with a small mechanism at the upper right; none of the leaf carries transcribed text.

Circle divided into six sectors
A large circle encloses a smaller concentric circle, and radii divide the ring into six sectors, with one sector split again by a further line. The construction reads as a study in the equal division of a circle. It stands alone as a geometric figure without accompanying text.
Two upright device studies
At the lower part of the sheet two tall, ornately built uprights are lightly sketched, each rising from a footed base, with a small separate mechanism drawn at the upper right. Their forms suggest mechanical or decorative stands. They are faint and were left untranscribed.
