    The condition most frequently treated by Infra-Red Rays is rheu- matism in its many forms, and much clinical success for this treatment has been mentioned by the many medical contributions on this subject. Infra-Red Rays are quite harmless in their effects and can be applied quite safely for long periods of treatment. The penetrative power of Infra-Red Rays is very striking, because it has been found that photographs of objects which are quite invisible to the human eye can readily be obtained on a photographic plate which has been made sensitive to Infra-Red Rays. Dr. Wright, of the Leek Observatory, in 1924, produced a photo- graph of the Sierra Nevada at a distance of 150 miles between camera and object. Mote recently, Stevens has produced an aerial photograph from a height of 23,000 feet, showing Mount Shasta at a distance of no less than 331 miles between camera and object. The penetration into human tissue is also very remarkable. Messts. Ilford, Ltd., produced an experiment on depth penetration as follows. An electric lamp was placed on one side of the human hand; on the opposite side of the hand, a photographic plate sensitive to Infra-Red Rays was placed, and an exposure was made. When the plate was developed, an outline of the bones of the hand was seen, which is proof that the rays have a greater degree of penetration than any other form of ray therapy apart from X-Rays. From this it will be seen that we have in Infra-Red Rays a very powerful therapeutic ally, and the profession have already embraced the advantages offered by this form of treatment, and as a result we find that the Duo-Ray Infra-Red Apparatus has been installed in the leading hospitals of the country, of which we would mention the London Hospital, London, E.; Guys Hospital, London, Siba The Royal Free Hospital, Gray’s Inn Road, London, W.C. 1; King’s College Hospital; British Red Cross Society for their rheumatic Glinicsmetc: It has been proved by several authorities, that Infra-Red Rays play a most important role in our existence; for instance, Dr. George Starr White reports that he made an experiment on plant life. Seeds and flowering plants wete planted in two rooms from which all visible light was excluded, one of these rooms was irradiated by the invisible Infra-Red Rays, the other was not so radiated. The result in the vegetable growth was most interesting as the seeds and plants sprouted and grew quite well, taking on all the colours of nature, in the room irradiated by Infra-Red Rays; but in the second control room only a few of the seeds sprouted, and the plants which grew at all were white and puny and soon withered. It should be noted that the beneficial effects of Infra-Red Rays are not primarily due to the heat produced and propelled on to the patient, because experiments have been made using an electric fan to deliver Page Iwo
