River-wave patterns around central, lateral and oblique obstacles
Four chapter headings with matching strip diagrams of the waves thrown by obstacles set in a river
Four short chapter headings for the water treatise, each with a column-like strip diagram at the right showing the wave pattern of an obstacle set in a river. The headings run through transverse obstacles of various widths placed mid-channel, lateral obstacles of various projections on the banks, obstacles set at various oblique angles mid-channel, and paired lateral obstacles whose fronts converge by varying amounts. Each is announced as an analogous figure to the one before it.

Transverse obstacles of various widths set mid-river
A heading on the various widths of transverse interpositions placed in the middle of the width of rivers, illustrated by the topmost strip diagram of the resulting waves.
Projections of lateral obstacles on the banks
A heading on the various projections of lateral obstacles placed on the banks of rivers, drawn as an analogous figure to the transverse case.
Oblique obstacles set mid-river
A heading on the various obliquities placed in the middle of the width of rivers, shown as another analogous figure of the disturbed current.
Converging fronts of paired lateral obstacles
A heading on the various convergences that the fronts of lateral obstacles placed on the banks of rivers make as they approach one another, the last of the analogous figures.
