Page 354 - Behold the child, by Nature's kindly law, Pleas'd with a rattle, tickled with a straw : Some livelier plaything gives his youth delight, A little louder, but as empty quite : Scarfs, garters, gold, amuse his riper stage, And beads and prayer-books are the toys of age : Pleas'd with this bauble still, as that before, Till tir'd he sleeps, and life's poor play is o'er.
Page 117 - From harmony, from heavenly harmony, This universal frame began : When Nature underneath a heap of jarring atoms lay, And could not heave her head, The tuneful voice was heard from high, Arise, ye more than dead ! Then cold and hot, and moist and dry, In order to their stations leap, And music's power obey. From harmony, from heavenly harmony. This universal frame began : From harmony to harmony Through all the compass...
Page 103 - When a ray of light passes from one medium to another, it is refracted so that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the velocities in the two media.
Page 38 - Avogadro's law states that equal volumes of all gases at the same temperature and pressure contain the same number of molecules...
Page 340 - The scientists of his day held that heat is an imponderable fluid, caloric, which flows from a body at a higher temperature to one at a lower, much as water flows from a place of higher to a place of lower level.
