Man, who represents the highest point of intelligence, and who offers us the only organism by which we arrive at a power that is semi-creative namely, THOUGHT is, among all zoological creations, the one in which combustion is found in its most intense degree; whose powerful effects may in fact be seen to some extent in the phosphates, sulphates, and carbonates which a man's body reveals to our analysis.
This explains its usefulness, as referred to later, for the titration of strong acids, such as hydrochloric acid, even in the presence of carbonates or sulphides in solution. Phenolphthalein, on the other hand, should be, as it is, the best of the common indicators for use with weak acids.
But it has a power of combining with certain other things and forming substances which, because they are combinations of carbon, are called carbonates. The commonest substance with which it will do this is lime.
If the contents of the stomach have a strong alkaline action, dilute with water, filter, and apply tests. Tests. The carbonates effervesce with an acid. The salts give a yellow precipitate with platinum chloride, and a white precipitate with tartaric acid. They are not dissipated by heat, and give a violet colour to the deoxidizing flame of the blowpipe. Stains on dark clothing are red or brown.
These stones, set in a mortar made of reddish earth, display their variegated colors, the warm yellows of the silex, the white of the lime carbonates, the russet browns of the sandstone, in many a fantastic shape. As you first enter it, the park is gloomy, the walls are hidden by creeping plants and by trees that for fifty years have heard no sound of axe.
Carbonates of strontia and of baryt, obtained by a new process, will shortly be sold in Paris at 3 francs the kilogramme. This discovery is expected to have a great influence on several important arts, such as the manufacture of glass, of soap, &c. Articles of furniture, jewellery, and every branch dependent on design, are now remarkable for a purer taste than that which they formerly exhibited.
He went to bed with dreams of vast new areas watered for summer rice, of pumping-stations lifting millions of cubic metres of water per day; of dykes to be protected by bulrushes and birriya weeds; of great desert areas washed free of carbonates and sulphates and selling at twenty pounds an acre; of a green Egypt with three crops, and himself the Regenerator, the Friend of the Fellah.
That domain included the amethyst, the emerald, the garnet, the aquamarine, the chrysoprase, the innumerable varieties of agate and jasper, lapis lazuli, felspar, obsidian; also various rocks, such as granite, serpentine, and porphyry; certain fossils, as yellow amber and some kinds of turquoise; organic remains, as coral, mother-of-pearl, and pearls; metallic ores and carbonates, such as hematite and malachite, and the calaite, or Oriental turquoise.
THE FORMATION OF CARBONATES. In attacking minerals water does more than merely take them into solution. It decomposes them, forming new chemical compounds of which the carbonates are among the most important.
On the Jaina River near the ruins of Buenaventura, I have seen promising ledges of copper ore. Copper carbonates predominated, the green ore known as malachite and the beautiful blue ore azurite were quite common, and white quartz, which on being broken showed little specks of native copper, was also to be found.
