Too much of them may be destructive even to life itself." Prescott had now paused and was regarding Kennedy contemptuously. Kennedy paid no attention, but continued: "Perhaps these mysterious rays may shed some light on our minds, however. Now, for one thing, ultra-violet light passes readily through quartz, but is cut off by ordinary glass, especially if it is coated with chromium. Old Mr.
Sulphuric acid and bichromate of potassium give a green colour, oxide of chromium. Precipitate with bichloride of platinum and with carbazotic acid. Much used in America by the Coffenite practitioners, and a valuable remedy for asthma. Symptoms. Nausea, vomiting, giddiness, cold sweats, prostration. Headache, giddiness, tremors, insensibility, and convulsions.
Ångström and Thalén pushed the coincidences to 450 for iron, while, according to the same excellent investigators, the following numbers express the coincidences, in the case of the respective metals to which they are attached: Calcium 75 Barium 11 Magnesium 4 Manganese 57 Titanium 118 Chromium 18 Nickel 33 Cobalt 19 Hydrogen 4 Aluminium 2 Zinc 2 Copper 7
All chromium salts, in fact, stain the therefore labelled chromaffin cells. The characteristic staining power appears to be dependent upon, or correlated with, the presence of the internal secretion of the medulla of the adrenal, adrenalin. For the content of adrenalin, as calculated chemically, and the depth of stain as seen under the microscope, rise and fall together.
He concluded, as he sat on the edge of his bed that night, rubbing them between his fingers, that they could be nothing but particles of keenly-tempered chromium steel. And chromium steel, he knew, was not used in gas pipes. It was foolish to think of it as a subject for lathe work. It was equally absurd to accept it as an everyday element in any plumber's everyday work.
From the corrected volumes of the two standard solutions, and their relations to normal solutions, calculate the percentage of chromium in the ore. It attacks iron and nickel as well; but crucibles made from these metals may be used if care is exercised to keep the temperature as low as possible.
Too much of them may be destructive even to life itself." Prescott had now paused and was regarding Kennedy contemptuously.

Several hours later, however, his patience snapped, and he roared and bellowed so loudly that a door opened and a frightened face appeared. Back of it was the chromium glitter of the ship's galley. "Be still, big one!" admonished the cook. "The captain is resting. He will have you chained standing if you disturb him with your bellowing."
Use hmmm sodium copper magnesium aluminium, iron and chromium. Got it?" "Yes, sir." He left, just as Devin returned with a large electrostatic voltmeter. "I'd like," said he, "to know how you know the voltage will range around eighty thousand." "K-ring excitation potential for mercury.
It is produced by simply putting a match to a mixture of aluminum filings and oxide of chromium, both metallic, and yet, as by magic, a mighty force is instantly created." The writer describes the discovery and processes at some length, and adds:
