"Alkaline" Quotes from Famous Books



... which I am strongly inclined to advise, this is boric acid in concentrated solution, that is, four per cent. at the ordinary temperature. This acid, whose singular influence on cell life has been shown by M. Dumas, is so slightly acid that it is alkaline to certain test papers, as was long ago shown by M. Chevreul, besides this it has no odor like carbolic acid, which odor often disturbs the sick. Lastly, its lack of hurtful effects on mucous membranes, notably ...

... the nut tree species prefer an acid to an alkaline soil? This is a question our questionnaire does not answer. Thirty correspondents say their trees are set in a lime soil, fourteen in an alkaline soil (which may or may not, in the commonly accepted usage of that term, have lime as a source of alkalinity). ...

... wind-swept dust, sometimes upwards of fifty feet in height, broke the uniformity. The soil was largely composed of powdered feldspar; but there were also tracts of gravel shingle, of yellow loam, and of alkaline dust. In some places there appeared a salt efflorescence, sprouting up in a sort of ghastly vegetation, as if death itself had acquired a sinister life. Elsewhere, the ground quaked and yielded underfoot, ...

... chemist, Dr. Leduc, has produced what he calls "osmotic growths," from purely unorganized mineral matter—growths in form like seaweed and polyps and corals and trees. His seeds are fragments of calcium chloride, and his soil is a solution of the alkaline carbonates, phosphates, or silicates. When his seeds are sown in these solutions, we see inert matter germinating, "putting forth bud and stem and root and branch and leaf and fruit," precisely as in the living vegetable kingdom. It is not a growth by accretion, as in crystallization, but ...

... again sowed with one bushel of wheat and dressed with 140 lbs. of Peruvian guano, costing $3, and the product was 22 bushels. Yet I would advise no one to rely upon guano exclusively. Its analysis shows that it contains salts of ammonia, alkaline phosphates and the other mineral elements necessary to produce the grain of wheat, but is deficient in most of the elements of the straw and roots of the plants. Hence, (says Liebig) 'a rational agriculturist, in using guano, cannot dispense with stable dung.' We should, therefore, be careful not ...

... their eyes, in spite of the breathless burning heat, the morning passed cheerfully. They even managed to satisfy their hunger with canned beef and canned brown bread. They had washed down the last of the unsavory lunch with the tepid, nauseously alkaline water from the olla when a gust of wind of tremendous proportions tore open the door flap and filled the room with a blinding swirl of sand. At the same moment there was a fearful crash from without, followed by the sound of breaking glass. Leaving Charley ...

Experiment in the same way with the two other principal acids and the two ...

... fruit a lighter color. In dipping and drying, the fruit, immediately after being cut from the vines, is either dipped in clear water to first rinse it of particles of dust and other foreign matter, or it is taken direct to the scalder and immersed in a boiling alkaline mixture called 'legia' (lye) until the grapes show an almost imperceptible cracking of the skin, the operation consuming perhaps from one-fourth to one-half of a minute. This dipping calls for skill on the ...

... might have added—what indeed we should infer by parity of reasoning—that when fermented liquors are avoided, animal food is no longer necessary, and by increasing the alkaline state of the stomach and fluids, may be hurtful. The truth is, they go best together. If we use flesh and fish, which are alkaline, a small quantity of gently acid drink, as weak cider or wine, taken either with our meals, or between them, may be useful. It ...

... mountain seems to be smouldering, as sulphur fumes and steam issue at many points, and the ground is covered with a friable white alkaline substance. In many a hollow the water bubbles with clouds of vapor and sulphuretted hydrogen; here the soil is hot and evidently underlaid by active fires.

... steam and sulphurous fumes. Others are of the clearest green or deepest, purest blue, through which thousands of silver bubbles shoot up to the surface, flash, and vanish. But the main use of the hot springs is found in their combination of certain chemical properties,—sulphur-acid, sulphur-alkaline. Nowhere in the world, probably, are found healing waters at once so powerful and so various in their uses. Generations ago the Maori tribes knew something of their effects. Now invalids come from far and near in hundreds and thousands, and when the distractions ...

... diverse kinds, in this ocean of the world, living creatures may be seen to be continually going forward and coming back. Every creature is afflicted by death. While dwelling in the uterus, all creatures are cooked in the fluid juices, that are alkaline and sour and bitter, of urine and phlegm and faeces,—juices that produce painful sensations and are difficult to bear. There in the uterus, they have to dwell in a state of helplessness and are even repeatedly torn and pierced. They that are covetous of meat are seen to be repeatedly ...

... keeping the fruit a certain time. These juices, together with those of the pear, the peach, the plum, and other such fruits, if taken without adding cane sugar, diminish acidity in the stomach rather than provoke it: they become converted chemically into alkaline carbonates, which correct sour fermentation. It is said in Devonshire that apples shrump up if picked when the moon is on the wane. From the bark of the stem and root of the apple, pear and plum trees, a glucoside is to be obtained in small crystals, which possesses the peculiar ...

... bodies,—of minerals,—we are under the necessity of bringing them into a liquid state, either by solution or fusion. Now vessels of glass, of porcelain, and of all non-metallic substances, are destroyed by the means we employ for that purpose,—are acted upon by many acids, by alkalies and the alkaline carbonates. Crucibles of gold and silver would melt at high temperatures. But we have a combination of all the qualities we can desire in Platinum. This metal was only first adapted to these uses about fifty years ...

It was a cacophony of smells, ranging from the heavily oppressive odour of the Dutch cheeses and the Gruyeres to the alkaline pungency of the Olivets.
