Cutting a file, materials by weight, and a line construction
A note on cutting a file, three figures of wood, lead and stone, a stone tied on a plank, and a fan of converging lines.
A short note in the upper corner records a method of cutting a file. On the left margin three figures are labelled wood, lead and stone, and on the right a stone is shown tied on a plank, suggesting studies of the weight or resistance of materials. Dominating the sheet is a large construction of straight lines converging to a single point within an arc and a grid, drawn without accompanying transcribed text; small mechanical clamps and screws are sketched down the right side.

Method of cutting a file
A note in the upper left corner records a way of cutting a file, that is, of raising the teeth on a metalworking file.
Three figures: wood, lead and stone
Three small figures on the left margin are labelled wood, lead and stone, apparently comparing these materials, perhaps by weight or resistance.
A stone tied on a plank
On the right half a stone is shown bound onto a plank, labelled 'stone'. It reads as an arrangement for testing the load or behaviour of a weight on a supporting board.
Fan of converging lines within an arc and grid
A large arc encloses a sheaf of straight lines that converge to a single point, laid over a squared grid. The construction is drawn without any transcribed caption.
Small clamps and screw fittings
Several small mechanical fittings — clamps, brackets and screws — are drawn down the right side of the sheet, separate from the transcribed notes.
