151 페이지 - DUKE'S PALACE. [Enter DUKE, CURIO, LORDS; MUSICIANS attending.] DUKE. If music be the food of love, play on, Give me excess of it; that, surfeiting, The appetite may sicken and so die.— That strain again;— it had a dying fall; O, it came o'er my ear like the sweet south, That breathes upon a bank of violets, Stealing and giving odour.— Enough; no more; 'Tis not so sweet now as it was before.
150 페이지 - That gravity should be innate, inherent, and essential to matter, so that one body may act upon another at a distance through a vacuum, without the mediation of anything else, by and through which their action and force may be conveyed from one to another, is to me so great an absurdity that I believe no man, who has in philosophical matters a competent faculty of thinking, can ever fall into it.
351 페이지 - Connected with the establishment of an university, or separate from it, might be undertaken the erection of an astronomical observatory, with provision for the support of an astronomer, to be in constant attendance of observation upon the phenomena of the heavens ; and for the periodical publication of his observations.
148 페이지 - I have seen the wild stone-avalanches of the Alps, which smoke and thunder down the declivities with a vehemence almost sufficient to stun the observer. I have also seen snow-flakes descending so softly as not to hurt the fragile spangles of which they were composed ; yet to produce from aqueous...
351 페이지 - Europe there are existing upward of 130 of these light-houses of the skies, while throughout the whole American hemisphere there is not one. If we reflect a moment upon the discoveries which in the last four centuries have been made in the physical constitution of the universe by the means of these buildings and of observers stationed in them, shall we doubt of their usefulness to every nation? And while scarcely a year passes over our heads without bringing some new astronomical discovery to light,...
116 페이지 - ... a concentrated beam across it through its two side windows then showed the air within it to be laden with floating matter. On the 13th it was again examined. Before the beam entered and after it quitted the case its track was vivid in the air, but within the case it vanished. Three days of quiet sufficed to cause all the floating matter to be deposited on the...
412 페이지 - This fool wishes to reverse the entire science of astronomy ; but sacred Scripture tells us that Joshua commanded the sun to stand still and not the earth.
117 페이지 - It is, in point of fact, the colour of the sky, and is due to a similar cause, namely, the scattering of light by particles, small in comparison to the size of the waves of light. "When this liquid is examined by the highest microscopic power it seems as uniform as distilled water. The mastic particles, though innumerable, entirely elude the microscope. At right angles to a luminous beam passing among the particles they discharge perfectly polarized light.
357 페이지 - The grounds were enclosed, a road built, rendering the access to the hill-top comparatively easy, the excavations for the foundations were made, and, on the 9th day of November, 1843, the corner-stone of the pier which was to sustain the great Refracting Telescope, was laid by John Quincy Adams, with appropriate ceremonies. On this occasion Mr. Adams made his last great oration. The deep interest which he had taken in astronomical science, warranted the hope that he might be induced to visit the...
