Abstract In the Bakerian Lecture, 1923, an experiment was described in which a large single crystal of aluminium was stretched till it broke. The resulting distortions were measured at various stages of the test and at the same time X-ray measurements were made to determine the orientation of the crystal axes. Various conclusions were drawn regarding the connection between the distortion and the crystal axes for the particular specimen with which the experiment was carried out. The present paper describes similar experiments made with several more specimens, in order to find out whether the conclusions previously reached are general in their application, and to settle several points which the previous experiment left in doubt. The use of a new X-ray spectrometer, specially designed for the purpose, and other minor improvements have enabled us to obtain greater accuracy than was possible previously.
