"An American scientist has just concluded a very interesting and suggestive experiment. He took a crushed sample of rich ore from Cripple Creek, which carried 1100 ozs. of gold per ton, and digested it in a very weak solution of sodium chloride and sulphate of iron, making the solution correspond as near as practicable to the waters found in Nature.
By this science you have learned beyond doubt that many of the commonest elements of the earth's crust exist also in other worlds, and, what is of great significance, that the materials most closely connected with living organisms on the earth, such as hydrogen, sodium, magnesium, and iron, are the very ones which are found most widely diffused among the stars.
At the beginning of the war higher education at G.H.Q. was somewhat neglected, and the company officer who desired to improve himself in the lethal arts had to be content with private study. Company officers went in for applied chemistry by making flares out of a test-tube full of water, delicately balanced in a bully-beef tin containing sodium.
"It may be well to keep in mind that when the druggist says potash he means potassium hydroxid, KOH, a compound of potassium, hydrogen, and oxygen, as the name indicates." "You mentioned the word chlorin," said Mr. Thornton. "That is another element?" "Yes, that is a very common element. Ordinary table salt is sodium chlorid: NaCl.
Behind this gaseous spectrum was found a faint continuous spectrum ascribed to the nucleus, which apparently both reflects the sunlight and gives forth the light of a glowing solid or liquid. Subsequently sodium and iron lines were found in cometary spectra.
The results exceeded the dreams of the most visionary. At the very outset, in 1860, it was shown that such common terrestrial substances as sodium, iron, calcium, magnesium, nickel, barium, copper, and zinc exist in the form of glowing vapors in the sun, and very soon the stars gave up a corresponding secret.
Weigh out 25 grams of sodium thiosulphate, dissolve it in water which has been previously boiled and cooled, and dilute to 1000 cc., also with boiled water. They should, therefore, be protected from light and heat. Iodine solutions are not stable for long periods under the best of conditions.
As the reaction between sodium thiosulphate and iodine is not always free from secondary reactions in the presence of even the weakly alkaline bicarbonate, it is best to avoid the addition of any considerable excess of iodine.
Beyond this, I'll mention that sodium batteries have been found to generate the greater energy, and their electro-motor strength is twice that of zinc batteries." "Captain, I fully understand the excellence of sodium under the conditions in which you're placed. The sea contains it. Fine. But it still has to be produced, in short, extracted. And how do you accomplish this?
If a few grains of sodium bromide were to produce the same effect, they would be just as welcome. The whole consideration moves in a sphere in which only physiological and psychological processes are happening.
