under the skin of pregnant guinea pigs. After allowing sufficient time for the compound to filter through the mother's body into its offspring's circulatory system, thescientists removed the embryo and analyzed it chemically. Despite careful testing of the vitamin C found in the embryo, highly-sensitive Geiger counters failed to pick up any trace of radioactive carbon. Thus it became apparent that the vitamin present could have come only from food eaten by the parent guinea pig. Further Studies. Another problem the research group is attacking, is the disappearance of vitamin C in the adrenal glands after an injection of ACTH. It has been found that test animals injected with the hormone experience a sharp drop in the amount of ascorbic acid in their adrenals. Several possibilities have already been tested, and the evidence so far indicates that the vitamin does not disintegrate into other compounds hut leaves the adrenals intact. Superconcentrated G r a p e Juice C a n Be D i l u t e d Sîx-to-One A "superconcentrated" grape juice which can be diluted with six parts of water to one part of juice has been developed by scientists at the Eastern Regional Research Laboratory, Department of Agriculture. A four-ounce can of the new product yields 70% more juice than the present six-ounce can which is diluted only three to one. The process for making t h e concentrate involves stripping the juice of its volatile or aromatic flavors and concentrating these stripped flavors to about 150 times the flavor strength of fresh juice. After the removal of pectin to prevent gelling, the juice is concentrated and t h e concentrated flavors returned to it. The process was first perfected by ERRL in 1944 for apple juice concentration.
LOF R e s e a r c h G r a n t s Six major projects dealing with fundamental research in glass, including some preparing for the oncoming application of atomic force to industry, are now being supported by Libbey-Owens-Ford Glass Co. Among the special projects sponsored by LOF is one dealing with fundamental glass studies related to nuclear physics and atomic energy in connection with the Phoenix Project at the University of Michigan, Ann Arbor, Mich. The overall project is bringing together more than 400 scientists in widely scattered fields to pool their work to "make a united attack on the problems of how to live with the atom." Robert L. Hess will surpervise the glass studies. In connection with the LOF program there will be graduate fellowships directed by Dr. Hess at University of Michigan. Lihhey-Owens-Fmd is also sponsoring Ο L U Μ Ε

Survey of Food and Nutrition Research A third survey of food and nutrition research in the United States is being u n dertaken by the National Academy of Sciences-National Research Council under contract with the U. S. Department of Agriculture. T h e two previous surveys published in 1948 a n d 1950 afforded a compilation of projects, organizations, a n d professional personnel t h e n current in this field. All phases of food a n d nutrition research active in academic, governmental, a n d industrial laboratories were included. This consolidation of the research work a n d workers into a central register has afforded a basis for t h e coordination a n d evaluation of research programs in t h e area. T h e third survey will follow t h e plan of the earlier surveys a n d will bring the information u p to elate. In addition, it will include suggested food a n d nutrition research projects in areas where further work is indicated.
