Pagina 20 - ... we may without hesitation conclude, that those equivalent quantities, which we have learned to appreciate by proportionate numbers, do really express the relative weights of elementary atoms, the ultimate objects of chemical research.
Pagina 14 - Laboratory. the powers of elastic fluids to abstract or conduct away heat from solid surfaces, is in some inverse ratio to their density, and that there is something in the constitution of the light gases, which enables them to carry off heat from solid surfaces in a different manner from that in which they would abstract it in gaseous mixtures, depending probably upon the mobility of their parts...
Pagina 36 - ... at right angles to it, directed as in the figure. Through the centre and at right angles to the plane of the slip of card, there is made to pass a slender stem of wood, at the two ends of which are fixed, in planes parallel to the slip of card AB, the circular discs of card, marked respectively with the letters N and S, and with arrows parallel to, but pointing in a contrary direction to the one at c. The same marks must be put on the reverse of each of the three pieces of card, so that when...
Pagina 113 - The yellow mass thus obtained must then be dissolved in hot water, and the liquor filtered in order to separate it from the sediment. After this it must be diluted with water, and sulphuric acid poured upon it of such a strength as to produce a fleecy precipitate of a superb yellow colour, which on being washed on a cloth freely dissolves in ammonia, and yields a yellowish liquor: into this is poured an excess of ammonia so as to discolour it entirely. The dye is then obtained, and any shade may...

Pagina 22 - I condensed air nearly five times, and ignited iron wire to whiteness in it by the voltaic apparatus, but the combustion took place with very little more brightness than in the common atmosphere, and would not continue as in oxygen, nor did charcoal burn much more brightly in this compressed air than in common air. I intend to repeat these experiments, if possible, with higher condensing powers : they show sufficiently, that, (for certain limits at least) as rarefaction does not diminish considerably...
Pagina 212 - Journal, vi. 317) proposes the following process: " To the muriatic or nitric solution of lime and magnesia, add sulphate of ammonia in sufficient quantity; evaporate the mixture gradually to dryness, and then heat it to redness till it ceases to lose weight, by the volatilization of the muriate or nitrate of ammonia formed: note the weight of the mixed salt, reduce it to powder and wash it with a saturated solution of sulphate of lime till all the sulphate of magnesia appears to be dissolved; dry...
