Wheeled machine with an opening head, and its dimensions
A device measured in braccia, a hopper that empties from above, and an inverted balance sketch
The sheet is dominated by a wheeled machine drawn on an inclined plane, with a long beam extending up and to the left and a bladed part below, plus a separate wheel-and-axle at the left. A caption gives its measurements in braccia: wheels half a braccio high, a 'head that opens' half a braccio high, 1 1/3 braccia wide at the mouth, 1 1/2 at the top and 1 3/4 long. A lower note describes a container ('rabbia') emptied from above through its wider part, and a small balance diagram with the figures 3, 12 and 4 is sketched with the sheet turned upside down.

Dimensions of the wheeled machine
The caption below the figure lists measurements for the device: the wheels half a braccio high, the head that opens half a braccio high, 1 1/3 braccia wide at the mouth, 1 1/2 braccia at the top and 1 3/4 braccia long. The figures scale the wheeled machine drawn above.
Vessel emptied from above
A note by the lower figure describes the bottom of the 'rabbia', which is emptied from above through its wider part. It corresponds to the tapering bucket-like vessel drawn at the lower right.
Balance diagram
Sketched with the sheet inverted is a small balance schema annotated with the figures 3 and, on the arm, 12 and 4. It reads as a study of a balance's proportions or moments.
