Electricity at Home and Abroad

\ A. GERMAN clock manufacturer has devised an alarm clock with an electric light bulb attached, so arranged that when the alarm rings, the light is switched on automatically, to shine on to the slumberer’s face. = * ™ SEVERAL layers of heavy cloth are cut out at one operation by electri-eally-operated shears, which save time and labour. They are run by a motor, which delivers power through a Series of gears to the cutting blades. * & a EG weakness in young chickens, which is really a form of rickets, has been combated by feeding with codli rer oil. It has, however, been found that yeast, after. being exposed to ultravidlet rays, is cheaper, easier fed, and less likely to leave undesirable flavours in the flésh.. = . a z= AN electric blanket, now on the market, is particularly adapted to the use of persons whose health requires much fresh ‘air, or who are in the habit of sleeping out in all weathers. The blanket is full single-bed size, weighs no more than an ordinary quilt, and plugs in to any wall point or light socket. ‘ ‘ ue z HE value of irradiation by ultraviolet rays for destroying the germs that produce boils has already been pointed out in these columns, but a new treatment is now in foree. A of electronic bullets, fired with electricity. as low as thirty volts, is directed on to the affected part with definite germ-killing effect, and further encourages the creation of new, healthy tissue. JLLECTRICAL current, passed through the ground, is being successfully used by two French scientists, to explore the interior of the earth, as far as thirty-one miles below the surface. At such a depth, formation cannot be accurately ascertained, but the method is proving of great value to geologists in locating mineral deposits nearer the surface. A current of about two amperes is used and careful readings of voltage and current taken. = * 2 FLLECTRICITY is now being used to . revive apparently still-born inwith great success. Where difficulty is experienced in inducing the child to breathe, electrodes are applied to both sides of either the neck or ehest, and a weak current’ passed through the body. 3y the first application a nerve leading to the diaphragm is excited, and by the second the diaphragm muscle itself is acted upon, forcirig expansion of the lungs, or, in other words, artificial breathing. A man, apparently dead of electric shock, has been revived by the same means,
