"From one end of a scale-beam, suspend a cylindrical metal bucket, b, with a solid cylinder, a, that fits accurately into it hanging below. Conterpoise with weights (shot or sand) in the opposite scale-pan. Immerse a in water, and the counterpoise will descend, as if a had lost some of its weight. Carefully fill b with water. It will hold exactly the quantity displaced by a. Equilibrium will be restored." -Avery 1895

"It is evident that, when a solid is immersed in a fluid, it will displace exactly its own volume of the fluid. Immerse a solid cube one centimeter on each edge in water, so that its upper face shall be level and one centimeter below the surface of the liquid, as shown. The lateral pressures upon any two opposite vertical surfaces of the cube, as a and b, are clearly equal and opposite." -Avery 1895
