...Bridgeport, broke through the ice and drowned. The tragedy made a doubly strong impression on Bessie Pastor because she did a lot of skating herself. Then & there she resolved that she would some day create a safe kind of synthetic ice-not artificially frozen water, but some other solid compound that would offer a skater a smooth gliding surface. It might have other advantages over natural ice, but in Bessie Pastor's mind its primary quality would be safety...
...chemicals responsible are complex compounds of chlorine and naphthalene, recognized for some time as the cause of skin diseases affecting industrial workers handling them. The higher the amount of chlorine present in the compound, the greater the damage, both to the skin and to the liver, Dr. Drinker has found...
From the research Dr. Drinker has been able to set standards of air purity which can be maintained by ventilation and which will ensure freedom of the workers from possible injury. The simple compound, trichlornapthalene can be present up to 10 milksops per cubic meter of air without ill effects. The more complex compounds, tetrachlornaphthalene, pentachlornap thalene, hexachloranapthalene and chlorinated biphenyl, can be present at safely only to the extend of half a milligram per cubic meter...
...their juices. This liquid was highly infectious to normal plants. But the deadly principle could not be cultured like a bacterium. Dr. Stanley found that it could be digested - that is, destroyed - by certain enzymes such as pepsin. This was important. Pepsin digests only proteins. Finally, using an ammonium compound which nudges proteins out of solution, Dr. Stanley isolated the virus as white crystals. When diluted 100,000,000 times, the crystals were still able to infect plants...
Physiologist John Raymond Murlin of the University of Rochester announced that he and assistants have just perfected a compound of insulin and hexylresorcinol which may be swallowed as a tablet. It is effective because the hexylresorcinol neutralizes pepsin and acid, and emulsifies fat. Thus there remains nothing to impede insulin's absorption by the diabetic's sugar-laden body...
