USES OF TELEVISION

JUSTICE AND HEALTH The marvel of television is being utilised in many ways (writes Joan Littlefield from London). Scotland Yard is interested because it thinks that the police messages concerning wanted Or missing people frequently broadcast on sound may soon be given in visual form. The 8.8. C. will probably be asked to collaborate in some practical tests, and if they are successful, viewers will be shown pictures of wanted persons and hear their official descriptions. Scotland Yard also thinks that, with a viewer in each police station^and a special transmitter on top of the Yard building, it may be possible to circulate television pictures of wanted persons and articles considerably in advance of the delivery of actual photographs. HEALING BY RAYS. At the Royal Westminster Ophthalmic Hospital television waves are being used to cure eye trouble. A specially designed short wave generator, like a glorified wireless set, is used for the treatment of inflamed and ulcerated eyes. The wave is the same as that used for television. The patient lies on a conch, one electrode under the pillow. Wooden arms support two other electrodes, one for each eye, covered with soft pads which press lightly on the eyes. Short waves penetrate the eye and produce a healing warmth which gradually clears up the infection. Longer waves are produced by another machine for the relief of glaucoma, a disease of the eyeballs. These waves reduce the painful pressure within the eyeball which, without operation, would eventually lead to blindness. The treatment is sometimes used in conjunction with a surgical operation. but in obtain cases the wireless waves ran dispense with the need for surgery.
