Seite 73 - Now Know Ye, that in compliance with the said proviso, I, the said Adolphe Nicole, do hereby declare that the nature of my said Invention, and the manner in which the same is to be performed, are...
Seite 287 - It was then evaporated to dryness, calcined in a low red heat, and the weight of the earthy sulphates was ascertained. (D. a.) The dry sulphates were washed with a small quantity of lukewarm water. In several instances, the loss of weight, thus sustained, was extremely trifling, nothing being dissolved but a very minute portion of sulphate of lime, of which earthy salt, solely, the residue was presumed to be composed. (D. b.) But in other cases, a considerable loss of weight ensued; and in these,...
Seite ix - Winsor do hereby describe and ascertain the nature of my said invention, and the manner in which the same is to be performed, as follows ; that is to say...
Seite 173 - In confortuity with this opinion, large sums of money are annually paid to foreign nations, for the supply of an article, which Great Britain possesses, beyond almost any other country in Europe, the means of drawing from her own internal resources.
Seite 178 - The uncrystallizable fluid is then let off through plug-holes at the bottom of the coolers ; and the Epsom salt, after being drained in baskets, is deposited in the store-house. This is termed single Epsom salts, and after solution and a second crystallization, it acquires the name of double Epsom salts.
Seite 229 - Quickness of solution, it is well known, is pretty nearly proportional, all other circumstances being equal to the quantity of surface exposed. And since the surfaces of cubes are as the squares of their sides, it should follow that a salt whose crystals are of a given magnitude will dissolve four times more slowly than one whose cubes have only half the size. That kind of salt, then, which possesses most eminently the combined properties of hardness, compactness, and perfection of crystals,, will...
Seite 291 - Marcet, loses 20.7 grains, by being calcined in a strong red heat. of of the actual above the estimated quantity, a. difference much too trivial to be admitted as an' indication of any sulphate with an alkaline base ; and arising, probably, from unavoidable errors in the experiment.
Seite 178 - The bitter liquor from the pits is boiled for some hours in the pans, which are used in summer to prepare common salt; and the impurities, which rise to the surface, are removed by skimming. - During the evaporation, a portion of common salt 'separates...
