Verso of the Antifriction Sheet (no writing)
Bears no writing of its own; faint forms show through from the recto
According to the e-Leo note this leaf was invisible before restoration and carries no writing. What can be seen is largely show-through from the recto: the radial octagonal frame with its projecting arms and, below it, the wheel-and-axle roller of the antifriction study. No independent text or diagram is recorded on this side.

Show-through of the recto's wheel-and-axle device
The forms visible on this side are the recto drawings showing through the thin sheet: a radial octagonal frame with projecting arms and, lower down, a horizontal wheel-and-axle roller. The verso itself carries no writing of its own.
