...Physicist Ralph C. Hartsough of Columbia that he had perfected a set of mirror-scales capable of weighing, distinctly and faithfully, down to one 280-billionth of an ounce. Gossamer quartz filaments balance the scales, the slightest titillation of which is reflected from their gold-mirrored surfaces by a ray of light. The ray is split by two half-mirrors, being reunited on the scale-mirrors, where any disparity between the wavelengths of the reunited portions is clearly seen as shadow bands.

They secured a combination of these salts and obtained X-ray pictures of the abdomen in which the gallbladder, previously invisible because of soft tissue, appeared almost as clearly as did the bones themselves. Stones in the gallbladder were localized easily. At the meeting of the American Roentgen Ray Society...
