Page 160 - ... which are separated by vast intervals of time, compressed into a day or an hour, everything like rest in spacial existence will forthwith disappear. We shall find the innumerable hosts of the fixed stars commoved in groups in different directions ; nebulae drawing hither and thither, like cosmic clouds ; the milky way breaking up in particular parts, and its veil rent; motion in every part of the vault of heaven.
Page 450 - Est prope Pittheam tumulus Troezena, sine ullis arduus arboribus, quondam planissima campi area, nunc tumulus; nam (res horrenda relatu!) vis fera ventorum, caecis inclusa cavernis, exspirare aliqua cupiens, luctataque frustra
Page 213 - ... light stream through the air ; so in the hotter zones of the earth, between the tropics, are there many thousand square miles of ocean which are similarly light-engendering. Here, however, the magic of the light belongs to the organic forces of nature. Light-foaming flashes the bursting wave, the wide level glows with lustrous sparks, and every spark is the vital motion of an invisible animal world. So manifold is the source of terrestrial light. And shall we conceive it latent, not yet set free...

We may conceive that the same bodies only become visible to us again after the lapse of several years, and when they have made many revolutions round their orbit." * * " Shooting stars fall either singly and rarely, and at all seasons indifferently, or in crowds of many thousands, (Arabian writers compare them to swarms of locusts,) in which case they are periodical, and move in...
Page 6 - The most important consequences of physical researches are therefore these: — To acknowledge unity in multiplicity; from the individual to embrace all; amidst the discoveries of later ages to prove and separate the individuals, yet not to be overwhelmed with...
Page 236 - St Patricius probably Bishop of Pertusa, was led to a very correct view of the phenomenon which presented itself in the appearance of hot springs near Carthage, at the end of the third century. "When questioned as to the cause of the boiling-hot water which poured out from the earth, he answered : — " Fire is nourished in the clouds, and in the interior of the earth, as Etna, and another mountain in the neighbourhood of Naples, inform you.
