Mechanical devices and a weighted quadrant
Faint sketches of pulleys, springs and fittings, with a graduated quarter-circle bearing a weight
This transmitted-light opening (146v and 150r) carries only the caption 'Figure' with no transcribed text, so the reading rests on what is drawn. The left leaf shows a graduated quarter-circle with a pivoted arm from which a weight hangs — a statics or measuring figure — above smaller line diagrams. The right leaf is filled with faint mechanical sketches: paired wheels or pulleys, blocks pierced for bearings, and scroll-like coiled forms. Further untranscribed notes accompany the figures and are not reproduced here.

Graduated quarter-circle with a hanging weight
A large quarter-circle is drawn on the left leaf with a vertical edge and a pivoted horizontal arm from which a small weight is suspended, resembling an instrument for gauging inclination or balance. No transcription accompanies it, so its exact purpose is not stated here.
Array of wheels, pulleys and scroll springs
The right leaf bears numerous faint device sketches, including paired circular wheels or pulleys, rectangular blocks pierced for bearings, and coiled scroll forms suggestive of springs. These are drawn without transcribed labels in the bundle.
