More water-wheel diagrams with proportional weights
Circular wheel figures labelled with paired numbers; the sheet is drawn inverted
On this inverted sheet Leonardo draws further circular water-wheel diagrams, each annotated with paired numbers (200/200, 50/150, 1/101) expressing the proportion of water to wheel. The figures continue the mill-wheel force studies of the adjoining leaves. Much fainter, untranscribed writing fills the rest of the page.

Water-wheel weighted 200 against 200
One circular water-wheel diagram is annotated 200 / 100-100 / 200, balancing the load of water against the wheel. The sheet is drawn upside down relative to its writing.
Wheel weighted 1 against 101
A further diagram carries the numbers 1 and 101, an extreme ratio in the same series comparing the weight of water to that of the wheel.
Circular wheel figures at lower right
Several circular figures with radiating spokes are grouped at the lower right, each tagged with paired numbers. Much fainter, untranscribed writing fills the rest of the leaf.
