الصفحة 334 - Lo, these are parts of his ways: but how little a portion is heard of him? but the thunder of his power who can understand?
الصفحة 327 - Into this wild abyss, The womb of nature, and perhaps her grave,* Of neither sea, nor shore, nor air, nor fire, But all these in their pregnant causes mixed Confusedly, and which thus must ever fight, Unless the almighty Maker them ordain His dark materials to create more worlds...
الصفحة 205 - May have broken the woof of my tent's thin roof, The stars peep behind her and peer; And I laugh to see them whirl and flee, Like a swarm of golden bees, When I widen the rent in my wind-built tent.
الصفحة 204 - In the space of one hundred and seventy-six years the Lower Mississippi has shortened itself two hundred and forty-two miles. That is an average of a trifle over one mile and a third per year. Therefore, any calm person, who is not blind or idiotic, can see that in the Old Oolitic Silurian Period, just a million years ago next November, the Lower Mississippi River was...

الصفحة 327 - The womb of Nature, and perhaps her grave, Of neither Sea, nor Shore, nor Air, nor Fire, But all these in their pregnant causes mixed Confusedly, and which thus must ever fight, Unless the Almighty Maker them ordain His dark materials to create more worlds — Into this wild Abyss the wary Fiend Stood on the brink of Hell and looked a while, Pondering his voyage; for no narrow frith He had to cross.
الصفحة 260 - Alas, your dear friend and servant, Galileo, has become totally and irreparably blind; so that this heaven, this earth, this universe, which with wonderful observations I had enlarged a hundred and thousand times beyond the belief of by-gone ages, henceforward for me is shrunk into the narrow space which I myself fill in it. So it pleases God; it shall therefore please me also.
الصفحة 167 - OLD TIME, in whose bank we deposit our notes, Is a miser who always wants guineas for groats ; He keeps all his customers still in arrears By lending them minutes and charging them years.
الصفحة 204 - And by the same token any person can see that seven hundred and forty-two years from now the Lower Mississippi will be only a mile and three-quarters long, and Cairo and New Orleans will have joined their streets together, and be plodding comfortably along under a single mayor and a mutual board of aldermen.
