Abstract
LAUE first used his method of X-ray analysis of crystal structure in 1912. The twenty-fifth anniversary of this event has been celebrated by Die Natunmssenschaften by the publication of two interesting articles on the progress made in this branch of crystal chemistry. One, by F. Laves (Naturwiss., 25, 705, 721 ; 1937), deals with the theory of the method and its development, and mentions its applications, particularly to the determination of atomic distances in crystals. A full account of our present knowledge of the radii of ions and atoms and their separations in crystals, and the dependence of these on the type of linking, ithods in the investigs given, and there is a useful bibliography. The second article deals with the use of X-ray interference meation of the fine-structure of animal tissues, and is contributed by F. O. Schmitt (Naturwiss., 25, 709 ; 1937). It mentions particularly progress made in the examination of nerve, sinew and muscle, and other tissues in which there is a high degree of orientation of proteins or lipins. It will be recalled that Current Science also had special articles in connexion with this anniversary (see NATURE, 139, 517 ; 1937).
