Page 92 - Faraday to expose the hydrate of chlorine in a closed glass tube, it occurred to me that one of three things would happen : that it would become fluid as a hydrate : that decomposition of water would occur ; . . . or that the chlorine would separate in a fluid state.
Page 145 - ... the views here developed, the mere difference of temperature between sunshine and shade, and air and water, or the effects of evaporation from a moist surface, will be sufficient to produce results, which have hitherto been obtained only by a great expenditure of fuel.

Page 96 - 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...
Page 393 - 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...
Page 279 - ... what consequences would follow ? The extremities of the strata now exposed to the sea, would at every ebb-tide be left dry, to a depth equal to the fall of the tide. Much water, formerly prevented from escaping by the altitude of the outlet, would now ooze out from the moist beds, and the subsiding force would act more powerfully in the absence of the water which filled every pore. All the strata above...
Page 92 - ... 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...
Page 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.
Page 90 - ... bottom of the tube, and gave a pressure of about 4 atmospheres. Being now cooled, there was an immediate deposit in films, which appeared to be hydrate, formed by water contained in the gas and vessels, but some of the yellow fluid was also produced. As this however might also contain a portion of the water present, a perfectly dry tube and apparatus were taken, and the chlorine left for some time over a bath of sulphuric acid before it was introduced. Upon throwing in air and giving pressure,...
