Mostly blank verso with a later column of numbers
Two mounted leaves, invisible before restoration; one bears a small drawing and figures in another hand
The verso comprises two mounted leaves that were invisible before restoration. The larger leaf (273a verso) is almost bare, showing only faint traces, while the narrow strip (273b verso) carries a small drawing and a short column of numbers written in a different hand. According to the transcription the other leaf (273b verso) is entirely devoid of writing and drawings. There is essentially no substantive text from Leonardo on this side.

A column of numbers in a later hand
The strip bears a small drawing and a short column of figures added in a hand other than Leonardo's. The numbers stand alone, without accompanying words. They were invisible before the sheet's restoration.
