...measurements of x-ray wave lengths convinced Compton that such rays, although a form of light, could act like bullets as well as waves. If on colliding with gas atoms they lost part of their energy as bullets, they should recoil as waves weaker in intensity and hence longer in wave length. In addition they should kick electrons out of the gas. With apparatus so sensitive that it measured one ten-millionth of the energy of a mosquito climbing an inch of screen, he showed that this was true. This "Compton effect" went far to explain photo-electricity...
...past few years," he declared, "there have been three outstanding cosmetic procedures that have been dangerous to the general public: Removal of superfluous hair by X-ray which has resulted in scars and cancer; the use of certain dyes on the eyelashes and eye-brows which has caused blindness and death; and the use of thallium acetate in creams to remove superfluous hairs which has caused serious illness and death...
Restorative treatment and X-ray research occupied the attention of the Technical Research department throughout the year. The chief undertaking in the restorative line was the retransference of a large Sienese painting of Girolamo di Benvenuto. In X-ray work, an extended study of early American painting was carried through...
...present, Burroughs is conducting an extensive study of the style of Rembrandt and his pupils, as shown by the X-Ray. An exchange of these shadowgraphs with institutions in Europe has already begun and will be continued during the coming year...
Burroughs has photographed many of the leading American works about which there has been doubt as to who the painter was. In some cases, however, he has been unable to convince the experts that he was right, for the X-Ray is a fairly recent development, and there is tendency to ignore his findings...
