Страница vii - Phoebus replied, and touched my trembling ears: "Fame is no plant that grows on mortal soil, Nor in the glistering foil Set off to the world, nor in broad rumour lies, But lives and spreads aloft by those pure eyes And perfect witness of all-judging Jove; As he pronounces lastly on each deed, Of so much fame in heaven expect thy meed.
Страница 393 - A Description and Draught of a new-invented Machine, for carrying Vessels or Ships out of, or into, any Harbour, Port, or River, against Wind and Tide, or in a calm.
Страница 442 - True happiness is of a retired nature, and an enemy to pomp and noise ; it arises, in the first place, from the enjoyment of one's self ; and, in the next, from the friendship and conversation of a few select companions...
Страница 475 - ... might perhaps have been conjectured ; but it could not have been inferred from his usual occupations, and probably is not generally known, that he was curiously learned in many branches of antiquity, metaphysics, medicine, and etymology, and perfectly at home in all the details of architecture, music, and law. He was well acquainted, too, with most of the modern languages, and familiar with their most recent literature. Nor was it at all extraordinary to hear the great mechanician and engineer...
Страница 471 - Not to perpetuate a name which must endure while the peaceful arts flourish, but to show that mankind have learned to honour those who best deserve their gratitude, the King, his ministers, and many of the nobles and commoners of the realm, raised this monument to James Watt, who directing the force of...
Страница 462 - The Clouds that gather round the setting sun Do take a sober colouring from an eye That hath kept watch o'er man's mortality ; Another race hath been, and other palms are won. Thanks to the human heart by which we live, Thanks to its tenderness, its joys, and fears ; To me the meanest flower that blows can give Thoughts that do often lie too deep for tears.
Страница 241 - Johnson had been with us: for it was a scene which I should have been glad to contemplate by his light. The vastness and the contrivance of some of the machinery would have " matched his mighty mind."

Страница vii - That life is not as idle ore, But iron dug from central gloom, And heated hot with burning fears, And dipt in baths of hissing tears, And batter'd with the shocks of doom To shape and use.
Страница 476 - It is needless to say that, with those vast resources, his conversation was at all times rich and instructive in no ordinary degree ; but it was, if possible, still more pleasing than wise, and had all the charms of familiarity, with all the substantial treasures of knowledge. No man could be more social in his spirit, less assuming or fastidious in his manners, or more kind and indulgent towards all who approached him. He rather liked to talk, at least in his...
