Excerpt from An Elementary Treatise on Hydrostatics: For the Use of Junior University Students The characteristic distinction of solids and fluids as to the transmission of pressure evidently arises from the mutual rela tions of their constituent atoms, so that solid bodies only trans mit pressure in the direction of its action; but fluids transmit pressure equally in all directions from the absence of stable rela tions between contiguous atoms. Fluids are subdivided into non-elastic fluids or liquids; and elastic fluids or gases and vapours. Definitions. The mass of a portion of fluid is the quantity of matter which it contains as measured by its inertia, and is pro portional to its weight at the same place. The weight of a body, as in dynamics, is the pressure produced by it under the action of the force of gravity.
