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...

Page 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...
Page 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...
