Side 81 - Lighter than air, Hope's summer-visions die, If but a fleeting cloud obscure the sky ; If but a beam of sober Reason play, Lo, Fancy's fairy frost-work melts away ! But can the wiles of Art, the grasp of Power, Snatch the rich relics of a well-spent hour? These, when the trembling spirit wings her flight, Pour round her path a stream of living light, And gild those pure and perfect realms of rest Where Virtue triumphs and her sons are blest...
Side 331 - An admirable and most forcible way to drive up water by fire, not by drawing or sucking it upwards, for that must be as the philosopher calleth it, Intra sphceram activitatis, which is but at such a distance. But this way hath no bounder if the vessels be strong enough...

And a man that tends the work is but to turn two cocks, that one vessel of water being consumed, another begins to force and re-fill with cold water, and so successively, the fire being tended and kept constant, which the self-same person may likewise abundantly perform in the interim between the necessity of turning the said cocks.
Side 6 - Yard when compared with a pendulum vibrating seconds of mean time, in the latitude of London, in a vacuum at the level of the sea...
Side 360 - I intend, in many cases, to employ the expansive force of steam to press on the pistons, or whatever may be used instead of them, in the same manner as the pressure of the atmosphere is now employed in common...
Side 457 - I have shown that chemical attractions may be exalted, modified, or destroyed, by changes in the electrical states of bodies; that substances will only combine when they are in different electrical states; and that, by bringing a body naturally positive artificially into a negative state, its usual powers of combination are altogether destroyed...
