Chapters on eddies and jets of water rising into the air
A plan of books 9–13 on the forms, effects, benefits and harms of eddies
The page is a table of planned books, numbered 9 through 13, on eddies (retrosi): their forms, their operations, and the benefits and harms they cause. Further headings extend the treatise to the collisions of jets of water surging up into the air at different velocities and various obliquities. It closes with propositions comparing oblique, thin and thick jets of water in terms of their driving power.

Planned books on the forms and effects of eddies
Book 9 on the forms of eddies; Book 10 on the operations of eddies; Book 11 on the benefits of eddies; Book 12 on the harms of eddies. A further book treats waters surging up into the air with various obliquities and equal velocities.
Collisions and driving power of water jets
Book 13 treats the collisions of waters among themselves as they surge into the air at different velocities. A more oblique jet strikes against a less oblique one while being more powerful and less thick; thin water may be driven up into the air by a greater power than thicker water.
