Popularne fragmenty
Strona 158 - And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also. And God set them in the firmament of the heaven to give light upon the earth, and to rule over the day, and over the night, and to divide the light from the darkness: and God saw that it was good. And the evening and the morning were the fourth day.
Strona 162 - Towards the morning of the 13th of November, 1799, we witnessed a most extraordinary scene of shooting meteors. Thousands of bodies and falling stars succeeded each other during four hours. Their direction was very regular from north to south. From the beginning of the phenomenon there was not a space in the firmament equal in extent to three diameters of the moon which was not filled every instant with bodies or falling stars. All the meteors left luminous traces or phosphorescent bands behind them,...
Strona 88 - Ye men of Ephesus, what man is there that knoweth not how that the city of the Ephesians is a worshipper of the great goddess Diana, and of the image which fell down from Jupiter?
Strona 88 - So that not only this our craft is in danger to be set at nought ; but also that the temple of the great goddess Diana should be despised, and her magnificence should be destroyed, whom all Asia and the world worshippeth. And when they heard these sayings, they were full of wrath, and cried out, saying ; Great is Diana of the Ephesians.
Strona 100 - Cleaves to his back; a famish'd face he bears; His arms descend, his shoulders sink away, To multiply his legs for chase of prey. He grows a wolf, his hoariness remains, And the same rage in other members reigns.
Strona 167 - While earnestly listening for the cause, I heard a faint voice near the door calling my name. I arose, and taking my sword, stood at the door. At this moment, I heard the same voice still beseeching me to rise, and saying ' O my God, the. world is on fire...
Strona 163 - The first appearance was that of fireworks of the most imposing grandeur, covering the entire vault of heaven with myriads of fireballs, resembling skyrockets.
Strona 123 - Look, how the floor of heaven Is thick inlaid with patines* of bright gold: There's not the smallest orb, which thou behold'st, But in his motion like an angel sings, Still quiring to the young-eyed cherubim: Such harmony is in immortal souls; . But, whilst this muddy vesture of decay Doth grossly close it in, we cannot hear it.
Strona 278 - Now, the temperature of any part of the earth's surface depends mainly, if not entirely, on its exposure to the sun's rays. Whenever the sun is above the horizon of any place, that place is receiving heat ; when below, parting with it, by the process called radiation ; and the whole quantities received and parted with in the year must balance each other at every station, or the equilibrium of temperature would not be supported. Whenever...
Strona 117 - Hail, great physician of the world, all hail; Hail, mighty infant, who, in years to come Shalt heal the nations and defraud the tomb; Swift be thy growth ! thy triumphs unconfin'd ! Make kingdoms thicker, and increase mankind.
