Mechanical sketches; facing leaf blank
Sketched apparatus on the verso; the facing recto is blank, and further writing on the sheet is untranscribed.
The transcription records only that the right leaf (249r) is a folio without writing or figures, and the scan confirms it is blank apart from its folio number. The left leaf (252v), by contrast, carries a column of notes and a group of small technical sketches, including a vertical shaft bearing a horizontal disc with cross-arms, a curved hull-like form with two upright poles, a symmetrical winged shape enclosed in a rectangle, and jotted numbers with a fraction. This writing on the left leaf is not part of the supplied transcription and is noted here without being read.

Shaft-and-disc apparatus with vertical rods
In the upper zone of the left leaf a vertical shaft is drawn carrying a horizontal disc set with radiating cross-arms, beside two thin upright rods. A curved hull-like form with two tall poles sits alongside. The forms read as a small mechanical apparatus.
Winged form within a frame
Below the apparatus a symmetrical winged shape is enclosed in a rectangular frame, with a short note beneath it. The frame and the accompanying jotted numbers and fraction are untranscribed in the supplied text and are not read here.
