Page 86 - The weight of the body is either totally or partially overcome by its buoyancy, by which it is concluded that a body immersed in a liquid loses a part of its weight equal to the weight of the displaced liquid.
Page 73 - Pascal's law, for it was first enunciated by that distinguished geometrician. Pressure exerted anywhere upon a mass of liquid is transmitted imdiminished in all directions, and acts with the same force on all equal surfaces and in a direction at right angles to those surfaces.
