The same mechanical apparatus, repeated
A red-chalk sketch identified as the apparatus already drawn on folio 41v
A single red-chalk drawing occupies the sheet, showing the same apparatus that appears on folio 41v: a curved cradle-like base supporting a framed structure, an upright, and a horizontal bar or roller at upper right. No transcribed text accompanies the drawing; the identification comes from the scholarly caption alone.

Repeat study of the cradle apparatus
The machine is sketched loosely in red chalk, its curved cradle and framed superstructure repeated from the previous folio. A bar or roller projects at the upper right. The sheet carries no further transcribed annotation.
