Abstract
CERTAIN banded structures seen in cast α-brass after annealing have been identified by several investigators as true twins. Recently we have made an observation which suggests that there may exist structures that appear to be twins, but that are not twins. The observations were made upon two large cast copper crystals joined at a natural boundary which lay almost perpendicular to the external surface of the sample. Into this bicrystal, zinc was diffused by exposing it to the vapour from α-brass turnings at a temperatiire of 775° C. The system was enclosed in an evacuated silica tube. Zinc penetrated to a uniform depth over the entire surface of the specimen and gave a layer of perhaps half a millimetre of yellow brass.

After having been approved by the authors and finally passed for press, the block for the diagram illustrating the communication by Dr. J. B. Speakman and E. Stott in NATURE of March 5, p. 414, was unfortunately inverted. The axes of the figure are, of course, correct; but the graphs should be inverted in relation to these axes.
