Strona 27 - But to derive two or three general principles of motion from phenomena, and afterwards to tell us how the properties and actions of all corporeal things follow from those manifest principles, would be a very great step in philosophy, though the causes of those principles were not yet discovered: And therefore I scruple not to propose the principles of motion abovementioned, they being of very general extent, and leave their causes to be found out.
Strona 347 - Rosse), and a vast multitude more have been found to present that mottled appearance which renders it almost a matter of certainty that an increase of optical power would show them to be similarly composed. A not unnatural or unfair induction would therefore seem to be...
Strona 354 - ... whose mottled and curdling light evidently indicates by a sort of granular texture its consisting of stars, and when examined under the great light of Lord Rosse's reflector, or the exquisite defining power of the great achromatic at Cambridge, US, is evidently perceived to consist of clustering stars. There can therefore be little doubt as to the whole consisting of stars, too minute to be discerned individually even with these powerful aids, but which become visible as points of light when...
Strona 545 - Verrier, and not with the intention of interfering with his just claims to the honours of the discovery ; for there is no doubt that his researches were first published to the world, and led to the actual discovery of the planet by Dr. Galle, so that the facts stated above cannot detract, in the slightest degree, from the credit due to M. Le Verrier.
Strona 347 - ... present that mottled appearance which renders it almost a matter of certainty that an increase of optical power would show them to be similarly composed. A not unnatural or unfair induction would therefore seem to be, that those which resist such resolution do so only in consequence of the smallness and closeness of the stars of which they consist ; that, in short, they are only optically and not physically nebulous.
Strona 574 - Ilia arcana non promiscue nee omnibus patent, reducta et in interiore sacrario clausa sunt. Ex quibus aliud haec aetas, aliud quae post nos subibit, dispiciet. Tarde magna proveniunt.
Strona 406 - La lumière qui émane des corps solides et liquides incandescents , est partiellement polarisée quand les rayons observés forment avec la surface de sortie un angle d'un petit nombre de degrés; mais il n'ya aucune trace sensible de polarisation lorsqu'on regarde de la même manière dans le Polariscope des gaz enflammés. Cette expérience démontre...
Strona 27 - Philosophia Propositiones deducuntur ex Phaenomenis, et redduntur generales per Inductionem. Sic impenetrabilitas, mobilitas, et impetus corporum et leges motuum et gravitatis innotuerunt. Et satis est quod Gravitas revera existat, et agat secundum leges a nobis expositas, et ad corporum coelestium et maris nostri motus omnes sufficiat (Principia, Amsterdam, 1714, p.
Strona 195 - ... a broad skirt to its southern border like a vast curtain, without an impression amounting almost to conviction, that the milky way is not a mere stratum, but annular, or at least that our system is placed within one of the poorer or almost vacant parts of its general mass, and that eccentrically, so as to be much nearer to the region about the Cross, than to that diametrically opposite to it.
Strona 48 - ... of those great deposits of dynamical efficiency which are laid up for human use in our coal strata. By them the waters of the sea are made to circulate in vapour through the air, and irrigate the land, producing springs and rivers.
