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 v - Tis midnight : on the mountains brown The cold, round moon shines deeply down ; Blue roll the waters, blue the sky Spreads like an ocean hung on high, Bespangled with those isles of light, So wildly, spiritually bright ; Who ever gazed upon them shining And turned to earth without repining, Nor wished for wings to flee away, And mix with their eternal ray...

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 204 - 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 upward of one million, three hundred thousand miles long, and stuck out over the Gulf of Mexico like a fishing rod.
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 - 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...
