Wolfgar was not dead; but when we picked him up it was obvious that he was dying. The violet beam vanished as his body struck it vanished with a hiss and splutter, and a puff of sulphuric smoke that mingled with the smell of burning garments and flesh. Georg and I leaped forward. Argo was standing transfixed by surprise at what Wolfgar had done; and as the beam died, Georg was upon him.
When I took charge of the poop at midnight Buckwheat relieved the steward in the vigil over the cabin floor; and as I leaned on the rail at the break of the poop, while my four hours dragged slowly by, least of all did I apprehend danger from the cabin especially when I considered the two-gallon pail of raw sulphuric acid ready to hand for the first head that might arise through an opening in the floor not yet made.
My friend usually kept the simple alkaloid in a paper, and dissolved it as he needed it in clear water, sometimes substituting an equivalent of "Magendie's Solution," which contains sixteen grains of the salt diffused through an ounce of water by the addition of a few drops of sulphuric acid.
To ascertain this, the latter is added to the former drop by drop so long as the color is removed. If it be desired to estimate the silica in the same test, the iron, as when it is analyzed for silica, may be also dissolved in sulphuric acid, and afterward oxidized with nitric acid, after which the solution is boiled to near dryness, so that the organic substances are completely destroyed.
just because Jonson wrote that and I published it, my paper was confiscated, Jonson was boiled in oil for ten weeks, and I was seized and thrown into a dungeon where a lot of savages from the South Sea Islands tattooed the darned old jingle between my shoulder blades in green letters, and not satisfied with this barbaric act, right under the jingle they added the line, in red letters, 'This edition strictly limited to one copy, for private circulation only, and they every one of 'em, Apollyon, Mazarin, and the rest, signed the guarantee personally with red-hot pens dipped in sulphuric acid.
If a carbonate, chloride, or nitrate, be present in the native binoxide, it must be removed with some sulphuric acid. This is afterward neutralized with a little caustic soda. This method yields the following results for its value in amount of manganese to 100: 99.91-99.902-99.895, and can be executed in about twenty minutes.
But if you dip a glass rod into a small quantity of sulphuric acid, and merely touch the harmless-appearing mixture with the wet end of the rod, the dish which contains it becomes instantly a roaring furnace of fire, vomiting forth a fountain of burning balls, and filling the room with a dense, black, suffocating cloud of smoke.
As zinc is one of the metals most readily attacked by acids, ordinary galvanized iron is not suitable for positions where it is to be much exposed to an atmosphere charged with acids sent into the air by some manufactories, or to the sulphuric acid fumes found in the products of combustion of rolling mills, iron, glass, and gas works, etc., and yet we see engineers of note covering-in important buildings with corrugated and other sheets of iron, and using galvanized iron tie rods, angles, and other constructive shapes in blind confidence of the protective power of the zinc coating; also in supreme indifference as to the future consequences and catastrophes that arise from their unexpected failure.
Once he cried out that he had been drinking sulphuric acid, and his throat and mouth were completely burnt away, leaving a gaping wound. She made tea for him, guessing that this was merely a picturesque way of telling her he was thirsty. But he thought she was poisoning him, and dared not drink the tea.
"Oh, they're easy, once you get used to them," said the young inventor, with a smile. "Perhaps it will be easier if I say that sometimes selenium is found in native sulphur. Selenium is usually obtained from the flue-dust or chamber deposits of some factory where sulphuric acid is made. They take this dust and treat it with acids until they get the pure selenium.
