The flying radio laboratory of the Bell Telephone Laboratories is shown on our cover this week. Fully equipped with radio-receiving and -transmitting apparatus, this plane reveals the problems that telephone engineers will have to confront when aerial travel is as common as railroading, and the flying traveler will want to keep in touch by telephone with his office. This is the plane from which telephone conversations were recently held with London. WARNS OF SUNBURN DANGERS With the present vogue of tanned skins and with our new knowledge of the health-giving properties of the sun’s rays, the danger of sever burns from overexposure to the sun is apt to be forgotten. A severe sunburn may be dangerous as well as uncomfortable. Burns from the sun’s rays are comparable to any other kind of burns, and may even be fatal. "With all its curative power, sunshine may become a menace to health when improperly used," warned Dr. James S. Walton of the New York State Department of Health. "The blistering caused by sunshine does not differ in any way from the blistering caused by fire or by live steam. Its destructive action on the skin is the same. Extensive sunburn causes the same high fever, delirium, serious meningitis. Death may follow as in similar burns by other agencies." GROWTH VITAMIN FOUND IN MILK Milk contains a hitherto unrecognized factor, which is vitamin in character and is essential for the growth of chicks and for the prevention of a peculiar type of paralysis that results in incurable deformities if long continued, according to an experiment recently finished by L.C. Norris, G.F. Heuser, and H.S. Wilgus, Jr., of the Cornell University agricultural experiment station. It is possible that the effects obtained from this factor have previously been credited to vitamin B. |
