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.
Seite 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

Seite 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...
Seite 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.
