Treatise page with tiny marginal hill sketches
Mirror-script prose with small pen sketches of pointed peaks in the upper margin; not transcribed here
The leaf is filled with Leonardo's mirror-writing in two paragraphs, each opened by a short heading, with a heading also running across the top of the column. In the upper right margin is a small cluster of pen-drawn pointed forms resembling distant hills or peaks. The page has no other diagrams, and its text is not transcribed in this edition. It belongs to the discursive leaves cut from Notebook A and later restored.

Marginal sketch of pointed peaks
A small group of pen strokes in the upper right margin forms several pointed, triangular shapes suggesting distant hills or mountains. The mark is a quick marginal jotting rather than a finished study. It sits beside the opening lines of the text, whose wording is not transcribed here.
Two headed paragraphs of untranscribed prose
Below the top heading the column runs on in two paragraphs of continuous mirror-script, each introduced by its own short heading. The text is not transcribed in this edition and is left unread from the image. Its ordered, precept-like arrangement matches the treatise prose of these leaves.
