Study sheet: arched forms and a lever-and-funnel device
Small sketches of vaulted structures and hulls, with a lever mechanism marked 3000 at the right.
A crowded sheet of small pen studies. At the right a lever or balance arm carries a small wheel or weight above a funnel-shaped vessel, and beside this figure the number 3000 is written. The rest of the sheet is filled with sketches of arched and vaulted forms set on boxy bases, together with hull- or boat-like shapes, laid over faint traces of earlier calculation.

Lever with funnel vessel, marked 3000
At the right stands a mechanism with a lever or balance arm bearing a small wheel or weight over a funnel-shaped basin. The figure 3000 is inscribed beside it, evidently a quantity or weight tied to the device.
Arched and vaulted structures
Several small sketches show rounded arches and vaults springing from rectangular, boxy bases, resembling domed rooms or vaulted spans. They are drawn rapidly and repeated across the center and lower left of the sheet.
