...sturdy body bundled snugly against Minnesota's snow, Mrs. Maude Neale Lumsden, 26, of Salmo, B. C., entered huge (500 doctors) and busy Mayo Clinic last week. By & by a trim receptionist gave Mrs. Lumsden an envelope into which X-ray photographers, blood counters, uroscopists, gynecologists, internists and surgeons might insert their judgments of the young woman's distressed abdominal organs. Mrs. Lumsden distractedly examined the figure on her diagnosis envelope. With comprehension of the big number came the inner warmth which all men feel when they achieve distinction. Mrs. Lumsden...
...furnace, such metals as vanadium, titanium, columbium, zirconium, and the platinum group, which have been difficult to study because of their very high melting points, can be melted into very pure alloys. Then, through X-ray photographs, significant students can be made of the individual peculiarities of molecular structure and other physical characteristics...
...Repeater" tubes are used to magnify the voice thousands of times in long-distance telephoning; sound movies, the "electric eye," remote control devices, X-ray, and television are all applications of the vacuum tube...

...Greninger has also developed a method of utilizing X-ray diffraction comeras for the measurement of crystal spacings. Through the use of this camera one photograph taken in less than an hour and interpreted in a few minutes will completely establish the orientation of metallic crystals, whereas formerly a careful observer might spend the larger part of a day in getting the same results. This method has now been adopted as standard practice in most metallurgical laboratories throughout the country. Dr. Greninger is also engaged in the study of the change of crystal structure in the send state...
