Part of a building; two pyramids hung at their centre of gravity
An arcaded wall above two elongated pyramids suspended at their balancing point
The upper drawing shows part of a building: a wall pierced by openings and crowned with a range of round-headed arches, with the figures '7 and 7' noted beside it. Below are two elongated pyramids drawn in perspective, which the caption describes as suspended at their centre of gravity. The red chalk is faint throughout.

Part of a building with an arcade
The upper sketch is part of a building: a wall with door-like openings surmounted by a row of round arches. The caption records the figures '7 and 7'.
Two pyramids suspended at their centre of gravity
Two elongated pyramids are drawn lying in perspective; the caption identifies them as suspended at their centre of gravity, a study in balance.
Elongated pyramidal solids
The two lower figures are rendered as elongated pyramids, wireframe solids tapering to a point.
