“ The resistance of the aether does not sensibly affect the velocity of a body when this is sufficiently less than that of aetherial propagation ; but this resistance becomes a uniform pressure on the entire surface of a body, (supposed spherical,) and even determines its sphericity. 3d. Taking as unity the density of the fluid, the quantity of motion impressed by a body on the aether is equal to its volume multiplied by the square of its velocity ; which is also the measure of the total pressure on the surface of a body. ”

“ Propagated to the interior of the heavenly bodies, the pressure would produce the effect that all layers of equal thickness will inclose the same quantity of matter, and that the mean density is three times that of the surface. ”

“ He commences with the general recognition, "It is an idea quite old in science that the movements of the heavenly bodies may be explained by an external impulsion or by the action of a universal fluid. ”
