Show EFFECTS OF DIFFERENT COLORS. The Scientific American tells of some experiments experi-ments carried on by Prof. Redard of Geneva to show the effects of color on the human organism. The blue ray has so soothing an effect upon the nervous centers that it acts like a mild anaesthetic, anaes-thetic, and makes light operations without pain possible. pos-sible. (Young men who have blue-eyed sweethearts will confirm this discovery). Red light is exciting and irritating. That is what makes the bull hate a red flag. Yellow light has a depressing . action. That is what makes good men deplore yellow journalism. jour-nalism. But this professor tells how to apply the anaesthetic method with blue light. The patient is seated on a chair at ten inches from a fifteen-candle-power incandescent lamp. The bulb of the lamp is of blue glass and it has a nickeled reflector. The head of the patient is covered with a thin blue veil, and the vision is directed toward the lamp. After a few minutes the subject is found to be unconscious, and upon lifting the veil the pupil of the eye is found to be dilated and the regard fixed. At this time a tooth tan be extracted without pain. That is, in twenty-eight cases, twenty were a success, eight a failure. The study of light and of the primary colors is being pursued with more and more enthusiasm. Again and again the old command: "Let there be light," comes back with new significance, until some scientists believe that there is enough in light to eradicate disease from the human system. The X-ray is now used by most surgeons for all manner of surface sur-face sores, even surface cancers, with perfect success, suc-cess, for disease is of the darkness, and when that is penetrated by the light, the germs that burrow in the tissues wither and die. Every new door that science opensreveals new beauties and gives us a clearer vision of the wisdom and beneficence that from the beginning has ordered men's lives. |
