Impact and Rebound: the Angle of a Bouncing Body
The wider the angle of a strike and bounce, the farther the moving body ends from its start
Written on a leaf the edition notes as turned upside down, this page states a rule of impact and rebound: the greater the angle a moving body makes when it strikes and bounces, the farther the end of its motion lies from where it began. A small figure with letters is set along the right margin to accompany the rule. Most of the surrounding matter is in faded mirror script.

The wider the rebound angle, the farther the motion
The larger the angle of impact and rebound made by the moving body, the greater the distance between the end of its motion and its beginning.
Lettered figure of the rebound in the right margin
A small figure marked with letters is drawn along the right margin of the sheet to illustrate the striking and bouncing described in the rule.
