Seite 90 - ... acid be formed ; or that the chlorine would separate in a condensed state. This last result having been obtained, it evidently led to other researches of the same kind. I shall hope, on a future occasion, to detail some general views on the subject of these researches. I shall now merely mention, that by sealing muriate of ammonia and sulphuric acid in a strong glass tube, and causing them to act upon each other, I have procured liquid muriatic acid : and by substituting carbonate for muriate...
Seite 235 - Voyage in the middle of Autumn, and the Stupendous Scenery of the Alps in the depth of Winter.
Seite 410 - Turn your astonish'd eyes ; behold yon huge And unhewn sphere of living adamant, Which, pois'd by magic, rests its central weight On yonder pointed rock ; firm as it seems, Such is its strange and virtuous property, It moves obsequious to the gentlest touch...
Seite 94 - A gage being introduced into a tube, in which liquid nitrous oxide was afterwards produced, gave the pressure of its vapour as equal to above 50 atmospheres at 45°. Cyanogen. Some pure cyanuret of mercury was heated until perfectly dry. A portion was then inclosed in a green glass tube, in the same manner as in former instances, and being collected to one end, was decomposed by heat, whilst the other end was cooled. The cyanogen soon appeared as a liquid : it was limpid, colourless, and very fluid...
Seite 409 - Stone is an immense block weighing above sixty tons. The surface in contact with the under rock is of very small extent, and the whole mass is so nicely balanced that, notwithstanding its magnitude, the strength of a single man, applied to its under edge, is sufficient to make it oscillate. It is the nature of granite to disintegrate into rhomboidal and tabular masses which, by the further operation of air and moisture, gradually lose their solid angles and approach the spheroidal form. The fact...
Seite 293 - ... filled every pore. All the strata above low-water mark would thus collapse, and the surface of the marsh, instead of remaining at its original height, would sink below the level of the sea ; but the escape of the water from the strata would not, in such circumstances, be confined to the beds situate above the low water-line. Even those occupying a position considerably lower would be influenced by the change ; for...
Seite 369 - Selection of the Geological Memoirs contained in the Annales des Mines, together with a synoptical Table of Equivalent Formations, and M. Brongniart's Table of the Classification of Mixed Rocks, translated, with Notes, by De la Bêche, 8vo.
Seite 24 - ... increased, and the undulations were feebler. At a smaller distance the surface of the mercury became plane ; and rotation slowly began round the wire. As the magnet approached, the rotation became more rapid, and •when it was about half an inch above the mercury, a great depression of it was observed above the wire, and a vortex, which reached almost to the surface of the wire.
Seite 392 - there is great reason to believe that air exists in mercury, in the same invisible state as in water, that is, distributed through its pores ;" and to the disheartening fact, (if proved), that absorption of air " may explain the difference of the heights of the mercury in different barometers ; and seems to indicate the propriety of re-boiling the mercury in these instruments, after a certain lapse of time.
