Notes not in Leonardo's hand (two mounted leaves)
Source: 'writings not by Leonardo'; a later cursive transcription of technical notes
The source labels this sheet as writings not by Leonardo. It comprises two mounted leaves densely covered in a regular, left-to-right Italian cursive rather than Leonardo's mirror script, consistent with a later transcription. The untranscribed text is technical, its visible topics being light artillery on the left leaf and the raising of water on the right. None of this writing is reproduced here.

Left leaf: notes on light artillery
The source flags this sheet as writings not by Leonardo. The left-hand leaf is filled with a regular, left-to-right Italian cursive, unlike Leonardo's mirror script, whose visible subject is light artillery. The text itself is not transcribed here.
Right leaf: notes on raising water
The right-hand leaf, in the same regular non-autograph hand, concerns the descent and raising of water through a siphon. As with the left leaf, the source does not transcribe the text and identifies it as not Leonardo's.
