...usual chemical method of obtaining vitamins from fish oil is to remove the oil and leave the vitamin-like obtaining a carburetor by removing the rest of an automobile of which it is part. Distilling is a more efficient method of obtaining vitamins from oils, but distilling vitamins is not so simple as distilling whiskey. Vitamin distillation has been practical only in recent years, has not yet been completely commercialized. Last week, at scientific meetings in Ithaca, Manhattan and Washington, Dr. Kenneth Claude Devereux Hickman of Eastman Kodak laboratories, Rochester, N. Y.-a British bachelor of 41 who likes...
...development of new stills resulted not only in a new method of obtaining vitamins, but in the discovery that vitamins previously recognized as individuals were in fact whole tribes of near relations. Distiller Hickman found that as temperature increased, the distillation rate of each vitamin changed and each had its characteristic peak. By this means he established that different fishes manufacture different kinds of Vitamin D. Vitamin D obtained from bluefin tuna did not resemble, in distillation behavior, the vitamin from white sea bass. Cod-liver oil was found to contain two major Vitamin Ds and some minor ones, making...

...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...
