HE search for healing is age-old and in no branch of medicines and theurapetics has*it been so intensive as in the rheumatic group of diseases. his group is extremely widespread and, embracing as it does arthritis, sciatica and kindred ills, presents medicine's greatest problem in the present day.
The search has been particularly intensified in an effort to discover the values of various wave lengths in the spectrum. The iheurapetic value of sunlight is too well known to need mention.
This, however, is but a small part of the band itself, lying between the infra-red group and the violet and x-ray groups. At the other end of the spectrum are found the hertzian waves, and adjoining them a short wave band in which the rays known as "Heala" rays are found.
Many years ago Mr. T. W. Russell, the scientist, in attempting experiments with the wireless waves, noted that his body could act as an aerial and that the wireless waves transmitted from the transmitting station were conveyed through his body to the set. He continued his investiga-Yon, working down the spectrum nor the ordinary wireless waves to the short wireless waves, until he reached the remote end of the nfra-red zone, where a slight warmth bccare apparent. These wave lengths had a slight clinic value, and Mr. Russell then knew he was on the right track, To produce these curative wave lengths, however, was a problem as it could not apparently be a straightforward procedure. In order to carry out his experiments it became necebsary to concentrate upon a design, both in element and reflector that would keep amplification and magni-fiction and yet cut out direct ray on the body from the element.
After several years of experimenting he obtained special content, sauge, length and weight for he vire, and this had to be coiled on ira clay of a particular composition and design. A small reflector then kad to be produced to be fitted on the top of the element, which would deflect the rays into the back of the iwo reflector, so that they might se amplified and thrown back on the Boty in a parallel beam.
