Seite 8 - A Report to the Navy Department of the United States on American Coals, Applicable to Steam Navigation, and to other purposes.
Seite 158 - Thus, solidification has not as yet been conferred on a fluid by any degree of pressure. Again, that beautiful condition which CAGNIARD DE LA TOUR has made known, and which comes on with liquids at a certain heat, may have its point of temperature for some of the bodies to be experimented with, as oxygen, hydrogen, nitrogen, &c., below that belonging to the bath of carbonic acid and ether ; and, in that case, no pressure which any apparatus could bear would be able to bring them into the liquid or...
Seite 166 - ... which it could be subjected. Sulphurous acid froze into transparent and colourless crystals, of greater specific gravity than the liquid out of which they were formed. Sulphuretted hydrogen solidified in masses of confused crystals of a white colour, at a temperature of — 122° Fahr.
Seite 254 - Its solution in concentrated sulphuric acid has a magnificent purple colour, and is decomposed by water. Nitric acid, with the aid of heat, attacks the oil with prodigious violence, evolving copious red fumes, and generating oxalic acid, which appears to be the only product. It dissolves in a solution of caustic potash, forming a deep brown liquid, from which acids precipitate a resinous matter. With a slight heat, it explodes when acted upon by metallic potassium.
Seite 155 - Thilorier, have left a constant desire on my mind to renew the investigation. This, with considerations arising out of the apparent simplicity and unity of the molecular constitution of all bodies when in the gaseous or vaporous state, which may be expected, according to the indications given by tho experiments of M.
Seite 128 - KOROS nii-iit ions the occurrence of hot springs between U and Ts'ang. They are numerous in the mountains lying east from the Ma-p'-ham lake, especially at one place, where there is a hole out of which vapour continually issues, and at certain intervals, as in Iceland, hot water is ejected with great noise to the height of twelve feet. The water of the hot springs of Assam was found by Mr. J. PRINSEP to contain bitumen and sulphuretted hydrogen. One held in solution a portion of muriate of soda....
Seite 6 - HUTCHINSON read a paper on the nature and cause of the diurnal oscillations of the barometer.
Seite 176 - His experiments confirm the prevalence of the law that the force of vapour increases in a geometrical ratio for equal increments of heat, commencing at a given amount of pressure. The more volatile a body is, the more r'apidly does the force of its vapour increase by an augmentation of temperature, the increase of elasticity being directly as the volatility of the substance. By further and more accurate...
