The ebb and flow of the tide.

Where there is a larger quantity of water, there is a greater flow and ebb, but the contrary in narrow waters.

Look whether the sea is at its greatest flow when the moon is half way over our hemisphere [on the meridian].

Taken from The Notebooks of Leonardo da Vinci edited by Jean Paul Richter, 1880.
