Pagina 89 - ... fissure in it. He was surprised to find that the water of the pneumatic trough rose into this jar one and a half inches in twelve hours ; and that after twenty-four hours the height of the water was two inches twothirds above the level of that in the trough.
Pagina 335 - The salt and the manganese were well mixed and used in charges of 3$ pounds of the mixture. The acid and water were mixed in a wooden tub, the water being put in first, and then about half the acid ; after cooling the other half was added. The proportions of water and acid are 9 measures of the former to 10 of the latter.
Pagina 61 - ... a great quantity of heat. It is, therefore, evident that the melting ice receives heat very fast, but the only effect of this heat is to change it into water, which is not in the least sensibly warmer than the ice was before. .A thermometer, applied to the drops or small streams of water, immediately as it comes from the melting ice, will point to the same degree as when it is applied to the ice itself, or if there is any difference it is too small to deserve notice. A...
Pagina 353 - The kelp which contains most iodine, generally also contains most chloride of potassium, and it is for these two products that the substance is now valued, more than for its alkali. " The kelp broken into small pieces is lixiviated in water, to which it yields about half its weight of salts. The solution is evaporated down in an open pan, and when concentrated to a certain point, begins to deposit...
Pagina 98 - The heat excited by friction is not in proportion to the hardness or elasticity of the bodies employed ; on the contrary, a piece of brass rubbed with a piece of cedar- wood produced more heat than when rubbed with another piece of metal ; and the heat was still greater when two pieces of wood were employed.
Pagina 109 - ... sulphate of lead, instead of sulphate of the oxide of lead ; nitrate of potassa, instead of nitrate Of the oxide of potassium. In case more than one basic oxide of the same element is capable of 476 477 combining with acids, the distinguishing prefix of each is retained in the name of its salts ; as sulphate of protoxide of iron, and sulphate of sesquioxide of iron. These salts are also often called respectively protosulphate and persulphate of iron, the prefixes being understood to refer to...
Pagina 254 - ... the power of developing an infectious or contagious endemic or epidemic ; on the other hand, as Professor Graham has justly remarked, such infectious matters as are accessible to us — for example, " the matter of cow-pox may be dried in the air, and is not in the- least degree volatile. Indeed, the volatility of a body implies a certain simplicity of constitution, and limit to the number of atoms in its integrant particle, which true organic bodies appear not to possess. Again, the source of...
Pagina 91 - ... or one with oxygen into a vessel of hydrogen, the bladder and the vessel of gas both contain both gases, owing to the passage of the gases from' and into the bladder. It is also stated by Professor Graham, that if a bladder, half filled with air, with its mouth tied, be passed up into a large jar filled with carbonic acid gas, standing over water, the bladder, in the course of twenty-four hours, becomes greatly distended by the insinuation of the carbonic acid through its substance, and may even...
Pagina 206 - Fig. 591 the polar chain is composed of molecules of hydrochloric acid, extending from the zinc to the porous division at a, and of molecules of chloride of copper from a, to the copper plate. When the Cl of molecule 1 unites with zinc, the...
Pagina 428 - This is afterwards glazed, which is done by dipping the biscuit-ware into a tub containing a mixture of about 60 parts of litharge, 10 of clay, and 20 of ground flint, diffused in water to a creamy consistence, and when taken out enough adheres to the piece to give an uniform glazing when again heated.
