Water Jet from a Double Pipe
A hydraulic question, a physician's memorandum, and a faint parallelepiped
The main note is a hydraulic problem: a section of a double pipe from which a jet of water spurts, lettered g, a, n, f, with Leonardo asking how much higher the water g will rise when the pipe a n is made wider than the pipe g. A separate personal memorandum records that Giuliano da Marliano, a physician, has a steward without a hand. A parallelepiped with two notches is barely outlined on the sheet.

Does a wider pipe throw water higher?
A section of a double pipe throws up a jet of water, with the parts lettered g, a, n and f. Leonardo asks how much more the pipe a n, being wider than the pipe g, will make the water g spurt higher than if a n were equal to g f.
A physician's one-handed steward
A brief memorandum notes that Giuliano da Marliano, a physician, has a steward without a hand. It is one of Leonardo's jottings about people he knew.
Faint parallelepiped with two notches
A parallelepiped with two joints or notches is barely outlined on the page. It is only lightly sketched and left unfinished.
