Why circles on water do not break where they cross
A hydraulic question with intersecting circles and an analogous scale-like figure
Written upside down, the note asks why the circles that spread across water do not break one another where they intersect. Concentric circles crossing near the foot of the sheet illustrate the question, while an oval of overlapping scale-like lobes at the top is captioned only as an analogous figure. A few faint further jottings appear in the middle of the sheet that are not part of the transcription.

Why intersecting water circles do not break
The note asks why the circles that ripple out across water do not break one another where they intersect. Two overlapping sets of concentric circles at the foot of the sheet stage the question as a diagram of intersecting waves. It is a study of how wave rings pass through each other undisturbed.
Analogous figure
Captioned only as an analogous figure, an oval of overlapping scale-like lobes is drawn at the top of the sheet with no accompanying text. It appears to be offered as a visual analogy to the pattern made by intersecting waves. Faint additional writing in the middle band of the page is not transcribed in the bundle.
