Military architecture and a diagram of artillery fire
An octagonal lantern tower above a scheme of converging fire
The upper half of the sheet carries a carefully shaded drawing of a polygonal (octagonal) lantern or tower, its faces pierced by tall round-arched windows and capped by a pyramidal roof, with a second stepped block sketched beside it. Below, a geometric scheme pairs two circles with straight lines radiating to a common point, the artillery-fire construction the caption names. No running text was transcribed for this page; the descriptions rest on what is drawn.

Octagonal lantern tower with arched windows
A polygonal turret is drawn in perspective, its walls opened by tall round-headed windows and closed above by a many-sided pyramidal roof. A lower stepped structure sits to the left, studying the same massing.
Scheme of converging artillery fire
Beneath the tower two circles are set side by side with straight lines fanning inward to meet at a single point, laying out the paths of artillery shots. The caption identifies it as a diagram of artillery fire.
