There lay the significance of an announcement last week by 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. Thus, when the object weighed (1/29...
...natural instincts a scientist, however, President Little did not give up his research. With Professor W. T.

Berry of the Lynn General Electric Company, results were produced and ultra-violet rays were pronounced valuable in the curing of rickets in children. President Little recently called the X-ray harmful to the human body, after he had experimented extensively with its effects on mice...
