Shadows Cast by Three Spheres onto a Plane
Rays from three round bodies converge on a shaded rectangular ground
Three circles, drawn as spherical bodies, stand in a row across the upper part of the sheet, each carrying a short caption within its outline. Rays descend from a ruled line above the spheres and pass to a shaded rectangular plane below, where they cross at a single central point. A short centred heading and ruled divider break the mirror-written text beneath, and a small subsidiary figure appears at the lower right. None of the Italian is transcribed in this bundle, and further untranscribed text is present.

Three bodies and their derived shadows
Three equal circles are ranged side by side beneath a horizontal ruled line marked with points. From each body straight rays run downward and inward to a shaded rectangle, meeting at a common point at its centre. The figure studies how several bodies project light and shadow onto a receiving surface.
Heading and note beneath the figure
Below the diagram the mirror-written text is interrupted by a short centred word and a horizontal rule, marking a new note or proposition. A small secondary sketch stands at the lower right margin. This apparatus is not transcribed in the bundle.
