Abstract
We supposed with Archimedes that water and all the other fluid bodies surrounding the earth exert a compression towards the centre of the earth by the force of their own gravity. Consequently, they are arranged spherically about the centre of the earth. Moreover, we supposed, also with Archimedes, that the less compressed parts of the fluid are expelled and moved upwards by its more compressed and heavier parts. From this hypothesis, it is deduced that every fluid such as water has a gravity and exerts it even in its proper place and natural location, i.e. water itself, while immobile in all the water, exerts its gravity by compressing the underlying bodies.
