Whether the sun contains a mysterious element "coronium," unknown to the earth, or whether the phenomenon giving rise to the coronium theory is merely the reaction of a well known element such as oxygen under peculiar conditions on the sun, is one of the many important scientific problems which the Harvard-Technology instruments have been designed to solve...
...Jones industrial stock averages closed at 147. Next day Federal Reserve Board Governor Marriner Stoddard Eccles publicly pronounced the market sound, declaring: "I think there is an element of safety and of strength in the fact that security purchases are being financed out of cash. . . .

Heavier than any other element except uranium, protoactinium is radioactive. It is 25% rarer than radium in pitchblende. One ton of that mother ore was reduced to extract a half gram of protoactinium oxide. In a phosgene chlorinating bath this was transposed to a chloride. Using the method evolved by General Electric's famed Irving Langmuir. Dr. von Grosse spread the chloride on a tungsten filament in a vacuum, heated the filament, boiled off the chlorine, obtained his bit of pure protoactinium...
Interested in the possible value of the element for cancer therapy. Chemist von Grosse took a photomicrograph of his precious mite by the light of its own rays. The pictures showed something like a glowing shoe-button. Then he turned the stuff over to Chicago's Museum of Science & Industry to be placed on exhibition. The museum furnished visitors with a magnifying glass by which to inspect the speck, too small to be seen with the naked...
...while so that he could make more photographs. He took it into a darkroom illuminated only by the red glow of a photographic lantern, arranged his microscope and camera. In shaping the tungsten thread to which the protoactinium clung, he was a little too rough. The delicate element crumbled to invisible dust...
