Of the water that crosses one current over another at various angles. Of the water that at various angles crosses itself in reflected motions, and of that which crosses at the crests of the waves, and which crosses in the descent of the wave, and which in the trough of the waves. Some cross at various angles. A large reflected motion with a small reflected motion, and likewise a large wave with a small one, and an incident motion with a trough, or with reflected motions small with large.

Sometimes a reflected motion with an incident one. When trough with wave, when incident motion with reflected, small and large and at various angles.

Sometimes swift waters with slow, when eddies with waves or troughs or reflected motions or incidences of running water along various lines crossed one over the other. Courses along different lines one above the other.

Eddies by various contrary motions and entering one into the other.

Lengths of various curvatures of eddies, from the surface of the water to its bottom, intersecting one another.

Intersection of incident eddies with the reflected ones.

Of the waters interposed in any direction among the said accidents of the waters.
