A liberal amount of stable manure has been applied, and the land deeply plowed, harrowed and cultivated, but as soon as water gets on it, it forms a deep crust on evaporation. Will guano help, or is sodium nitrate or potash the thing? None of the things you mention are of any particular use for the specific purpose you describe.
The impurity was principally iron, a most unusual thing in my experience, and was due to two causes revealed by assay of the ore and analysis of the mine water, viz., an excess of arsenate of iron in the stone, and the presence in large proportions of mineral salts, principally chloride of Calcium CaCl., sodium NaCl, and magnesium MgCl2, in the mine water used in the battery.
It may be employed with some of the stronger organic acids, but the use of phenolphthalein is to be preferred. !Hydrochloric Acid and Sodium Hydroxide. Approximate Strength!, 0.5 N PROCEDURE. Measure out 40 cc. of concentrated, pure hydrochloric acid into a clean liter bottle, and dilute with distilled water to an approximate volume of 1000 cc.
We have seen a natural combination of zinc, lead, and iron, which, in our experience, ranks next; but the zinc is acted on by the chloride of sodium, and wears away too much of the material. Red lead, however, while covering the iron perfectly and effectually preventing rust, and also having but little disposition to chloridize, when it does, will foul both with grass and barnacles.
A quantity of the water, equal in bulk to one thousand grains of distilled water, was operated on for each of the following ingredients: Chlorine 0.66 Carbonic acid 0.16 Sulphuric acid 0.03 Soda and sodium 0.97 Magnesia 0.09 Lime 0.07 Potash traces Organic matter ,, Manganese ,, 1.98
DYSPEPSIA CURE. Powdered Rhubarb, two drachms: Bicarbonate of Sodium, six drachms; Fluid Extract of Gentian, three drachms; Peppermint Water, seven and a half ounces. Mix them. Dose, a teaspoonful half an hour before meals. FOR NEURALGIA. Tincture of Belladonna, one ounce; Tincture of Camphor, one ounce; Tincture of Arnica, one ounce; Tincture of Opium, one ounce. Mix them.
We have never found any other use for radium it is so active that it combines with water just as sodium does; it is very soft a useless metal, and dangerous to handle. Our chemists have never been able to understand it it is always in some kind of reaction no matter what they do, and still it gives off that very light gas, helium, and a heavy gas, niton, and an unaccountable amount of heat."
"There is an important movement on foot among us Westerners," I said, "in regard to a recommendation to the convention that the bottles containing the tartrate of antimony and potash, and the tartrate of sodium and potash be kept in a contiguous position on the shelf." "Gentleman to three-fourteen," said the clerk, hastily. I was whisked away to my room.
On the latter date, the continuous spectrum given by a reddish-yellow disc surrounding the true nucleus seemed intensified by bright knots corresponding to the rays of sodium. A comet discovered by Mr.
Dissolve 3 grams of sodium bicarbonate in 200 cc. of water in a 500 cc. beaker, and pour the cold solution of the antimony chloride into this, avoiding loss by effervescence. This is usually expelled by the heating upon the water bath; but if it is not wholly driven out, a point is reached during dilution at which the antimony sulphide, being no longer held in solution by the acid, separates.
