He science of hydrostatics treats of the nature, gravity, pressure, and motion of fluids in general, and of weighing solids in them. Definition A fluid is a body that yields to the least presof a fluid. sure or difference of pressures. Its particles are so small, that they cannot be discerned by the best microscopes; they are hard, since no fluid, except air or steam, can be pressed into a less space than it naturally possesses;7 and they 6 The doctrine of fluids is generally divided into three branches,--Hydrostatics, which treats of the gravity and equilibrium of fluids at rest; Hydrodynamics, which treats af fluids in motion j and Hydraulics, which treats of the construction of machines in which fluids are chiefly concerned.--Ed. 7 It is now found from many unquestionable experiments, made both in this country and on the continent, that most fluids are to a certain degree compressible. Mr. Canton having placed a glass tube filled with water, beneath the receiver of an air-pump, and removed the pressure of the atmosphere, found that the water expanded itself and rose in the tube. When the same glass tube was placed under the receiver of a condensing engine, and the air in the receiver greatly condensed,. the water was compressed, and sunk in the tube. When other fluids were subjected to similar experiments, he found them compressible in the following proportions:--Spirit of wine 6& millionth parts of the whole; oil of olives 48 millionth parts; rain water 46; sea water 40; and mercury 3.--For a farther must be round and smooth, seeing they are so easily moved among one another. All bodies, both fluid and solid, press downward by the force of gravity: but fluids have this wonderful property, that thei...
