*TEETH. Honey mixed with pure pulverized charcoal is said to be excellent to cleanse the teeth, and make them white. Lime-water with a little Peruvian bark is very good to be occasionally used by those who have defective teeth, or an offensive breath.
"But, Edward," said I, "why did those three powders turn black?" "Because they were calomel, my dear, and it was lime-water that was poured on them," said Mr. Smith. "Well, but why did not the others turn black too?" "Because the others were tartarized antimony." "Where did you get what was in the plates, that made the lights, you know?" "Rutherford had the material.
Then, you know that it has an effect, and becomes white in contact with lime-water; and when it does become white in that way, it becomes one of the constituents to make carbonate of lime or limestone.
The apparatus is contained in a box that likewise holds a bottle of lime-water sufficient for a dozen analyses, the table of proportions of CO , and the apparatus for cleaning the tubes. The entire affair is small enough to be carried in the pocket. J. Arnould, in Science et Nature.
To eliminate this element it would only be necessary to carry a certain quantity of lime-water, easily calculated, and by means of a fan or similar instrument to drive the whole of the air periodically through the vessel containing it.
After scalding, peeling, soaking an hour in clear lime-water to harden, they were rinsed clean, then dropped in thick boiling syrup, a few at a time, simmered an hour, then skimmed out, drained, sugared and dried under glass in the sun, or failing sunshine, upon dishes in a very slow oven. Full-dry, they were packed down in powdered sugar, in glass jars kept tightly closed.
The casks should be cleaned in the following manner: After washing each barrel clean, put in a lump of unslaked lime, and pour in a gallon of boiling water; bung it up, and roll the barrel several times a day, letting it lay with the bung down; in the evening, empty out the lime-water, and wash the barrel clean in several waters; after the water is drained out, burn a brimstone match in it, made of a piece of coarse muslin one inch broad, and four long, dipped in melted brimstone; light one end of the match, and put it in; put the bung on slightly, so as to hold the other end, and allow air sufficient to make it burn; when the rag has burned out, drive in the bung to keep in the sulphuric gas, which, if allowed time, will condense on the sides.
The proportion of this last gas, measured by the absorption of lime-water in graduated tubes, appeared more uniform than that of the oxygen, of which some individuals yielded almost double the quantity. From the curious phenomena observed by MM. Biot, Configliachi, and Delaroche, we might suppose, that the swordfish dissected by Dr.
You can readily prove the existence of carbonic and gas in the breathing, by simply breathing into a little lime-water; after breathing for a few seconds into it, a white film will form on the top; the carbonic acid gas from the breath unites with the lime of the lime-water and the product of the white film is carbonate of lime. Do you advise a bedroom to be darkened at night?
