The period of vibration or oscillations which make up light waves and whichthe human eye will respond to, are those above the infra-red rays or heat raysand those below the ultra-violet or invisible light rays. The difference betweenthe two is that the vibration of the infra-red is very small and the wave lengthvery long, while those of the ultra-violet region have a tremendous period of vi-bration and a very short wave length. The therapeutical work that has been conducted points to the fact that theultra-violet rays are most advantageous and consequently of greatest use in lighttherapy. We know that light rays from such sources as the Finsen, Minin, Ultra-violetand X-ray are each capable of exciting a normal, subnormal or abnormal humanreceiver. However, our scientists, not being satisfied with the belief of the existence ofanother source of vibration beyond the ultra-violet region, took another step inthis direction which proved to be successful, inasmuch as they have found a III I

It is believed that we are only beginning to learn of the real benefits to begained by the scientific application of light rays by skilled therapists. The author, who has been engaged in this, as well as the electrical field of re-search for many years, discovered a new ray which he christened the B-ray.The production of this new source of radiation is somewhat similar to the Ultra-violet ray, inasmuch as an arc is used; but two different arc electrodes are em-ployed in this work. The arc is produced between an electrode composed ofquartz and mercury with a second electrode of ordinary arc carbon. Fig. 102shows one of the complete arc lamps u
