Abstract
PROF. E. A. GUGGENHEIM'S letter in Nature of April 14 on the above subject reveals a serious lack of correlation between international organizations. The International Union of Pure and Applied Physics in 1948 and the International Union of Pure and Applied Chemistry in 1949 appear to have adopted “Å as the abbreviation for the ångström”, presumably ignoring the fact that the International Astronomical Union in 1938 had adopted the symbol “A” to represent “angstrom, the international wave-length unit”1. Both the definition of the unit itself and the standard tables of wave-lengths measured in terms of it are provided by the International Astronomical Union, and it would accordingly seem fitting that since universal use is made of these data, the name and symbol by which they are designated should not be violated.
