So also with the Christian Science attitude towards "drugs," the prescribing of which Mrs. Eddy places in the same category as the denial of God. An obvious comment suggests itself: If drugs cannot cure, it follows that they cannot hurt; will some adherent to this teaching show his consistency in the faith by swallowing a small, but sufficient quantity of oxalic acid? And so, finally, with Mrs.
Never allow dirty pots or pans to stand and dry; for it doubles the labor of washing. Pour in water, and use ammonia, and the work is half done. Scrape a little rotten-stone fine, and make into a paste with sweet oil. Rub on with a piece of flannel; let it dry, and polish with a chamois-skin. Copper is cleaned either with vinegar and salt mixed in equal parts, or with oxalic acid.
The principal inorganic corrosives are the mineral acids, the caustic alkalies, and their carbonates; the organic are carbolic acid, strong solutions of oxalic acid, and acetic acid. Symptoms. Burning pain in mouth, throat, and gullet, strong acid, metallic or alkaline taste; retching and vomiting, the discharged matters containing shreds of mucus, blood, and the lining membrane of the passages.
The comparison of the acid and alkali solutions was made, using methyl orange as an indicator, while the titration of the oxalic acid is made with the use of phenolphthalein. In the oxidation processes of volumetric analysis standard solutions of oxidizing agents and of reducing agents take the place of the acid and alkali solutions of the neutralization processes already studied.
Oxalic acid, so much the fear of those accustomed to the medicine Epsom salts, is made from that useful article, sugar, by uniting with it a smaller portion, more than it has naturally, of oxygen gas. But these most destructive substances are always found combined with others, which render them often perfectly harmless, and can be separated only by the skill of the chemist.
Oxalic acid can be prepared by an artificial process, with great ease, from sugar, and six times its weight of nitric acid, the former affording the carbon necessary to its formation, and the latter the oxygen.
Mitscherlich speaks of erosion of the gums and tongue with hemorrhage at the slightest provocation, following the long administration of dilute nitric acid. This was possibly due to the local action. According to Taylor, the smallest quantity of oxalic acid causing death is one dram. Ellis describes a woman of fifty who swallowed an ounce of oxalic acid in beer.
Many times the unknown contents of some bottle or package has been carelessly taken and found to be poison. Careless and stupid people often take, by mistake, with serious, and often fatal, results, poisonous doses of carbolic acid, bed-bug poison, horse-liniment, oxalic acid, and other poisons.
I have looked for work all day and have utterly failed to find it. Now I have a scheme and I know it will work. Oxalic acid eats away rust. If I had five cents' worth, I could earn a dollar I know I could." He looked curiously at me for a moment, and said with an oath: "By ! I've been on the Bowery a good many years and haven't been sold once. If you're a skin-game man, I'll throw up my job!"
Fatal Dose. Half an ounce. Fatal Period. Shortest, two hours; average, twenty-four hours. Death may occur after an interval of some weeks from destruction of the gastric glands and inability to digest food. =Oxalic Acid= is used by suicides, though not often by murderers. The crystals closely resemble those of Epsom salts or sulphate of zinc; oxalic acid has been taken in mistake for the former.
