Arsenic Poisoning Widespread, Beauty Parlor Clippings Show. Hair clippings collected from beauty parlors and barber shops and subjected t o chemical analysis show that very many of us are carrying around mild cases of arsenic poisoning without ever suspecting it. I t may become serious enough to cause "patch baldness," or bleachi n g ~or discolorations of the skin. This evidence that a considerable proportion of our population are "arsenic carriers" was presented by Drs. C. N. Myers and Binford Thorne, of the New York Skin and Cancer Hospital, before the American Chemical Society. The arsenic comes from the widespread use of poison sprays to protect fruit and other crops, and even from clothing made from cotton sprayed to keep off boll weevil.-Science Serwicc Teetotalers Nevertheless Have Ethyl Alcohol in Them. The question whether the brain, liver, blood, etc., of humans and animals that have never taken a drink of an alcoholic beverage, contain ethyl alcohol has interested biochemists in the past. By specially developed micro methods, Prof. Alexander 0. Gettler, toxicologist of Bellevue Medical College of New York, Joseph B. Niederl, and A. A. Benedetti-Pichler have actually isolated 100 per cent pure ethyl alcohol from the normal brain, liver, and blood. The isolated alcohol was shown a t the meeting of the American Chemical Society where the experiment was described by Prof. Gettk-Science Service Sweet Milk Corrodes Nickel. Sweet milk corrodes nickel, often used on milk cans and other utensils. H. A. Trebler, of Ithaca, N. Y.. and W. A. Wesley and F. L. Laque described the effects of operating conditions on corrosion of various parts of pasteurizing equipment before the meeting of the American Chemical Society. Both plant and laboratory tests were made. When milk is being heated, a film of protein protects the nickel, hut when milk is cooling corrosion is rapid. This depends on the amount of aeration, temperature, and other factors.-ScienceService Dates Have High Mineral Content. Dates were recommended as a dietary supplement, before the recent meeting of the American Chemical Society, by M. M. Cleveland and Professor C. R. Fellers of the Massachusetts Agricultural College. Analysis of imported dates from Iraq showed unusually high mineral content. The fruit is especially strong in potash, a necessary mineral food element.-Science Service
