Electroplating is the only practical way of putting on tungsten coats. But the electroplater needs a stable solution of a tungsten salt in water. Most tungsten compounds decompose in water or else are altogether insoluble. Professor Fink's accomplishment was to prevent the tungsten atom of his sodium tungstate molecule from going into another tungsten compound. The tungsten atom, thus kept free from changing relations, could be driven by an electric current and deposited on pieces of brass, copper, zinc, iron or carbon...
...living material out of dead is highly exciting. Basic material of all beings is protoplasm. Every body cell contains protoplasm, a gooey material like white of egg, one-fourth heavier than water. Protoplasm always contains at least twelve elements: calcium, carbon, chlorine, hydrogen, iron, magnesium, nitrogen, oxygen, phosphorus, potassium, sodium, sulphur. The living combination of these is exceedingly complex. Best of chemists have been unable to decipher the protoplasmic interrelations. Could they do "so, they could make protoplasm in their laboratories...

...fantastic mineral. The Eskimos thought that cryolite, which means "frost stone," was a mysterious kind of ice. It looks like ice, melts readily in a candle flame into something which especially puzzled Eskimos because it is not water. Found in Greenland, cryolite is a compound of fluorine, sodium and aluminium, is used commercially as a flux in smelting aluminium...
...Wrenshall developed a chaulmoogric acid in combination with an inorganic acid group. This is soluble in water, can be administered with an ordinary hypodermic syringe. More water-soluble than this double acid itself, and so more easily administered, is the sodium salt of this new acid. Tried out on dogs the Wrenshall acid, he reported, proved some six times more therapeutically active than the older ethyl-esters. The Territorial board of health decided to use at once the acid compound on human lepers...
