"Fluids gravitate in proprio loco the upper Parts continually pressing upon the lower: That this Pressure is not only propagated Downwards but even Upwards and Sideways according to all possible Directions; That a lighter Fluid may gravitate upon a heavier and an heavier upon a lighter; That a Fluid may sustain a Body heavi­er in Specie than it self and even raise it up; That a Fluid may detain a Body lighter in Specie than it self and even depress it. A gen-eral Experiment to prove that a competent Pressure of a Fluid may produce the remarkable Phænomena of the Tor­ricellian Tube the Pump Syringe Syphon pol­ished Plates and other Effects of the like Nature."
