"Alas!" said I, half mournfully, half angrily, "when you thus speak of Mind as distinct from Soul, it was only in that Vision which you bid me regard as the illusion of a fancy stimulated by chemical vapours, producing on the brain an effect similar to that of opium or the inhalation of the oxide gas, that I have ever seen the silver spark of the Soul distinct from the light of the Mind.
When the reduction of aluminic oxide by carbon is conducted without the addition of copper, a brittle product is obtained that behaves in many respects like pig iron as it comes from the blast furnace. The same product is formed in considerable quantities, even when copper is present, and frequently the copper alloy is found embedded in it.
This gas that is disengaged from the upper part of the fuel consists chiefly of nitrogen and carbonic oxide, mixed with volatile hydrocarburets derived from the fuel used. This gas, through the action of the air upon the fuel, is called "air gas," in order to distinguish it from the "water gas" formed in the second period of the process.
It is known to the chemist as CaCO3, and forms practically all of very pure limestones. Impure limestones contain some earthy materials that became mixed with the lime carbonate when the rock was being formed. Calcium Hydroxide is a compound made by permitting calcium oxide to combine with water, and is known as lime hydrate.
Sulphuric acid and bichromate of potassium give a green colour, oxide of chromium. Precipitate with bichloride of platinum and with carbazotic acid. Much used in America by the Coffenite practitioners, and a valuable remedy for asthma. Symptoms. Nausea, vomiting, giddiness, cold sweats, prostration. Headache, giddiness, tremors, insensibility, and convulsions.
The iron meteorites, besides metallic iron and nickel, of which they are almost entirely composed, contain hydrogen, helium, and carbonic oxide, and about the only imaginable way in which these gases could have become absorbed in the iron would be through the immersion of the latter while in a molten or vaporized state in a hot and dense atmosphere composed of them, a condition which we know to exist only in the envelopes of the sun and the stars.
But what faces these young folks make up at my good advice! They get tipsy on their rhymes. Nothing intoxicates one like his or her own verses, and they hold on to their metre-ballad-mongering as the fellows that inhale nitrous oxide hold on to the gas-bag." We laughed over this essay of the old Professor; though it hit us pretty hard.
But if the conjecture is pushed still further, and we suppose that the ore was not an oxide, but rich in iron, magnetic or spicular, the result would in all probability be a mass of perfectly malleable iron. I have seen this fact illustrated in the roasting of a species of iron-stone, which was united with a considerable mass of bituminous matter.
That is to say, at the time of ignition the chief product of combustion is carbonic oxide, and, unless sufficient air be added to convert the oxide to carbonic acid, a decidedly dangerous product is given off into the room. Yet, by means of a flue to carry off the poisonous gases from burning jets, the combustion of gas, creating a current, is made an aid to ventilation.
This is made as follows: 100 parts of fused zinc chloride, 85 parts of water, and 4 parts of zinc oxide are boiled together until a clear solution is obtained. This solution dissolves silk slowly in the cold, quickly if hot, and forms a thick gummy liquid. Wool, fur, and vegetable fibres are not affected by it.
