"Nitrogen" Quotes from Famous Books



... living together or working together who are a continual source of irritation to each other. It is just as impossible for such people to work in harmony as it is for two incompatible chemicals, as nitrogen and iodine. We do not try to over-ride the laws of Nature by trying to force these chemicals to stay together. It is just as impossible to force certain incompatible people to be harmonious. If society or business throws two such people together it would be wise for one to make a change ...

... contains a high percentage of nitrogen, but is said to differ from proteid in that it is not precipitated by C{2}H{6}O. It is usually homogeneous in appearance—sometimes granular—and may contain oil globules or sap vacuoles (Fig. 85, d), chromatin granules, and even sulphur granules. Sap vacuoles ...

... chemistry can as yet give but scanty information; it can tell that it is composed of carbon, hydrogen, oxygen, nitrogen, sulphur, and phosphorus, and it can also tell the percentage of each element, but it cannot give more than a formula that will express it as a whole, giving no information as to the nature of the numerous albuminoid ...
— Was Man Created? • Henry A. Mott

... chemical process called combustion, upon which a boiler depends for its heat. Ordinary steam coal contains about 85 per cent. of carbon, 7 per cent. of oxygen, and 4 per cent. of hydrogen, besides traces of nitrogen and sulphur and a small incombustible residue. When the coal burns, the nitrogen is released and passes away without combining with any of the other elements. The sulphur unites with hydrogen and forms sulphuretted ...
— How it Works • Archibald Williams

... nothing about an organic compound. What the elements are that compose the compound is not to be found out. That can be told beforehand with almost absolute certainty. What is wanted is to know how the atoms of carbon, hydrogen, oxygen, and nitrogen are linked together, for, strange to say, these differences of groupings, which may be found to exist between these three or four elements, endow the compounds with radically different properties and serve us as ...

... otherwise protected from the air, its carbon becomes charcoal. All plants contain this substance, it forming usually about one half of their dry weight. The remainder of their organic part consists of the three gases named above. By the word gas, we mean air. Oxygen, hydrogen and nitrogen, when pure, are always in the form of air. Oxygen has the power of uniting with many substances, forming compounds which are different from either of their constituents alone. Thus: oxygen unites with iron and forms oxide of iron or iron-rust, which does not resemble the gray ...

... the famous trapezium, and a nine-inch instrument sees two stars more. The shape of the nebula is changeable, and is hardly suggestive of the moulding influence of gravitation. It is probably composed of glowing nitrogen and hydrogen gases. Nebulae are of all conceivable shapes—circular, annular, oval, lenticular, [Page 218] conical, spiral, snake-like, looped, and nameless. Compare the sprays of the Crab nebulae above z Tauri, seen in Fig. 79, and the ring nebula, Fig. 80. This last possibly consists of stars, ...

... to make up the various substances which compose their tissues—to build up their wood, their leaves, their fruits, their blossoms—plants require hydrogen, nitrogen, and even small quantities of oxygen as well; but these various materials are sufficiently supplied in the water which is taken up by the roots, and they really contribute very little indeed to the bulk of the tree, which consists for the most part of almost pure carbon. If you were to take ...
— Science in Arcady • Grant Allen

... far as he was concerned the work was admirably done. He separated all the known ingredients of the air with a precision altogether remarkable; he even put it upon record that he had some doubt about the purity of the nitrogen. For more than a hundred years his determination was repeated by chemists all the world over, his apparatus was treasured in London, he became, as they used to say, 'classic,' and always, at every one of the innumerable repetitions of his experiment, that sly ...

... and most profitable labour on his farm, the countless millions of beneficent bacteria who, his willing slaves, are ceaselessly at work during hot weather forming root tubercles on his legumes, be it clover or cow peas, and so fixing for their lord the free atmospheric nitrogen contained in the soil. As Macaulay would say, "every school boy knows" now that leguminous root nodules are endotrophic mycorrhiza,—but the Romans did not! Nevertheless their empirical practice of soil improvement with legumes was quite as ...

... all the elements known to chemists, many of which have difficult names, such as oxygen and hydrogen. These two are the elements which make up water, and oxygen is an important element in air, which has nitrogen in it too. There are numbers and numbers of other elements perfectly familiar to chemists, of which many people never even hear the names. We live in the midst of these things, and we take them for granted and pay little attention to them; but when we begin to learn about other worlds ...

... pole being the cohesive or coherentific force, and the south or positive pole being the dispersive or incoherentific force: the first is predominant in, and therefore represented by, carbon,—the second by nitrogen; and the series of metals are the primary and, hence, indecomponible 'syntheta' and proportions of both. In like manner, sulphur represents the active and passive principle of fire: the contractive force, or negative electricity—oxygen—produces ...

... For many things it is well to begin the year before last. For good results one must begin even sooner. Here, for example, are the directions, as I interpret them, for growing asparagus. Having secured a suitable piece of ground, preferably a deep friable loam rich in nitrogen, go out three years ago and plough or dig deeply. Remain a year inactive, thinking. Two years ago pulverize the soil thoroughly. Wait a year. As soon as last year comes set out the young shoots. Then spend ...

... carrying on some experiments in fertilizing nut and other trees which should yield some very valuable information. I recently saw a plot of Castanea mollissima which had been treated with a 33-1/2% nitrogen fertilizer. Planted on poor, acid, eroded soils in the hill country, these have barely survived. After treatment, the yellow, stunted foliage changed miraculously to a striking dark green, the leaves grew larger, and the entire ...

... ten million cubic yards. [Footnote: Van Hise, p. 307, quoted from W. J. Spillman, "Report National Conservation Commission," 3:257-262.] This is, of course, inconsiderable in a short period but in a long period of years means a mighty loss of nourishing soil. With this loss is that of nitrogen, potassium, and phosphorus, things of which the farmer had not even heard the names a few years ago. The yield of farms in the United States during the last forty years does not show a decreased average, but it must be remembered that in this period there ...

... sand along the coast, possess contrivances similar to the round-leaved plant's to pursue their gruesome business. Why should these vegetables turn carnivorous? Doubtless because the soil in which they grow can supply little or no nitrogen. Very small roots testify to the small use they serve. The water sucked up through them from the bog aids in the manufacture of the fluid so freely exuded by the bristly glands, but nitrogen must be obtained by other means, even at ...

What would Joseph Priestley, the discoverer of oxygen, and Cavendish, the discoverer of nitrogen, think could they step into the laboratory of Professor Ramsay and see test-tubes containing argon and helium and krypton and neon and zenon? Could they more than vaguely understand the papers contributed in recent ...

... spores. There is no question of chemist's phosphorus here. This is a slow combustion, a sort of more active respiration than usual. The luminous emission is extinguished in the unbreathable gases, nitrogen and carbonic acid; it continues in aerated water; it ceases in water deprived of its air by boiling. It is exceedingly faint, however, so much so that it is not perceptible except in the deepest darkness. At night and even by day, if the eyes have been prepared for it by a preliminary ...

... Our bodies, which seemed so living and now prove so dead, have served us such a trick that we can have no confidence in anything connected with them. As with skin and bones to-day, so with protoplasm to-morrow. Protoplasm is mainly oxygen, hydrogen, nitrogen, and carbon; if we do not keep a sharp look out, we shall have it going the way of the rest of the body, and being declared dead in respect, at any rate, of these inorganic components. Science has ...

... ss-rays. Water exposed to their bombardment splits up into hydrogen and oxygen. And, again, the separated atoms may be in part recombined under the influence of the radiation. Ammonia splits up into hydrogen and nitrogen. Carbon dioxide forms carbon, carbon monoxide, and oxygen; hydrochloric acid forms chlorine and hydrogen. In these cases, also, recombination can be partially ...

... still more wonderful? The forms which we see grow out of substances and are supported by forces which we do not see. The stuff out of which all vegetable appearances are made is reducible to oxygen, hydrogen, carbon and nitrogen. How does it happen that this common stock is worked up in such different ways? Why is a lily woven out of it in one place and a dahlia in another, a grapevine here, and a honeysuckle there—the orange in Italy, the palm in Egypt, the olive in Greece and the pine ...

... history of those germs is really a wonderful thing, and books have been written about them. They exist in tribes, as it were; some of them can live only where oxygen is present, and some live on nitrogen only; others on carbon. But that is not all. Man has learned to use them, so they will work just as surely as our yaks work for us under ...
