...problem of securing sufficient light for photographing still remained. Further experiments with Magnesium flares indicated that it was difficult, but not impossible, to use this method of lighting. If the flare was lighted too soon, the turtle retreated to the sea; if too late, half of the episode was lost...

Doctoring Drugs. Drugs may be made more effective and less harmful to the patient by mixing a magnesium salt with them, according to the researches of Dr. Moses Leverock Crossley of Bound Brook, N. J. The magnesium salt acts upon the body allowing the drug to penetrate more freely, quickening the action, reducing the dosage in many cases. Magnesium made aspirin twice as effective; made morphine injections last four times their ordinary duration; made codein, which ordinarily has no effect on temperature, reduce fevers. Any salt of magnesium may be used...
Meteors, literally "things in the air," refer specifically to luminous bodies known as shooting stars, falling stars, fireballs, bolides. Traveling rapidly through the air, they generate intense frictional heat which burns up most of their material substance. Thus, they become "balls" of fiery gases and small particles of carbon, magnesium, sodium, etc. The explosion of a meteor is due to its rapid combustion in the dense atmosphere near the earth. It is estimated that some 20,000,000 meteors, which would be visible to the naked eye in the absence of sunlight, moonlight or clouds, enter the atmosphere every...
...sheet of chrome steel the flame left molten pools behind it. Significance: steel girders could be welded silently instead of noisily riveted;* the welds would not (as when an oxyhydrogen flame is used) be oxidized and thus weakened, they would be annealing instead. This is important in joining aluminum, magnesium and other light metals.) Alloy metals, too refractory to work with by present methods, could be used for building, thus conserving the world's iron...
