Column of calculations with small mechanical sketches
Arithmetic worked in columns, framed by faint studies of engines and fittings
The leaf carries a column of arithmetic calculations — figures such as 234, 156, 3517 and 1177 set out and summed — which is the only text recorded here. Around them are faint pen sketches: a slatted rectangular frame at upper left, small ladder-like uprights, and a few small mechanical fittings at the right, with a triangular structure showing faintly through the sheet. The scholarly subject tags associate this leaf with throwing engines and firearms — catapults, scythed chariots, arquebuses and small guns — though no such text is transcribed. Further untranscribed sketches are present on the sheet.

Column of calculations
A column of figures worked and summed — values such as 234, 156, 3517 and 1177 — is the only text on the leaf. The numbers are set out in stacked groups as if being added and checked.
Small mechanical fittings
At the right of the sheet are small pen sketches of mechanical fittings — little wheeled or screw-like devices — drawn in ink over the pale paper.
Faint engine showing through the sheet
A slatted frame at upper left and a faint triangular engine show through the paper. The scholarly tags associate this leaf with catapults, scythed chariots and small guns, though no such text is transcribed.
