Treatise page of four titled sections
Mirror-script prose, foliated 27, from the leaves cut from Notebook A; not transcribed in this edition
The leaf carries four short paragraphs of Leonardo's mirror-writing, each opened by its own brief heading, with a red folio number at the upper right and the oval Institut de France library stamp near the middle. A little offset script shows through at the lower margin from the facing leaf. The page has no diagrams, and its text is not transcribed in this edition. It is one of the discursive leaves cut from Notebook A and later restored.
On this page
Four headed sections of untranscribed prose
The column is broken into four short paragraphs of continuous mirror-script, each introduced by a heading set above it. No transcription is supplied here, so the wording is left unread from the image. The compact section-by-section layout is that of the treatise material on these leaves.
