Page 316 - NYMPHS ! you erewhile on simmering cauldrons play'd, And call'd delighted SAVERY to your aid ; Bade round the youth explosive STEAM aspire In gathering clouds, and wing'd the wave with fire ; Bade with cold streams the quick expansion stop And sunk the immense of vapour to a drop. — Press'd by the ponderous air the Piston falls Resistless, sliding through its iron walls ; Quick moves the balanced beam, of giant-birth, Wields his large limbs, and nodding shakes the earth.
Page 4 - But hydrostatics, as a branch of natural philosophy, treats of the nature, gravity, pressure, and motion of fluids in general ; and of the methods of weighing solids in them.
Page 381 - ... 1. The rising of the mercury presages, in general, fair weather, and its falling foul 'weather, as rain, snow, high winds, and storms.
Page 148 - We know now that the underlying principle is the same as in a mercurial barometer : it is the pressure of the atmosphere on the surface of the water in the well that pushes the water up into the pump.
Page 338 - The mercury is sustained in the tube by the pressure of the atmosphere on the surface of the fluid in the cup.
Page 290 - At Rosneath, near Glasgow, there is an echo that repeats a tune played with a trumpet three times completely and distinctly. Near Rome there was one that repeated what a person said five times. At Brussels there is an echo that answers 15 times.

Page 51 - In each of these different kinds of pumps which have been described, the total effort required to work the machine, independently of friction, is equal to the weight of a column of water, the base of which is equal to the area of a section of the working barrel, and the altitude equal to the distance between the surface of the wate/ in the reservoir and the point to which it is raised.
Page 118 - Hence he inferred that, though of equal weight, the bulk of the silver was greater than that of the gold, and that the quantity of water displaced was, in each experiment, equal to the bulk of the metal. He next made...
