## Measurements have been made of the stress required to cause the appearance of twins in single crystals of cadmium, both in tension and in compression. The results are consistent with the view that, if a twin nucleus is present, the shear stress in the twinning plane which is needed to cause it
It is suggested that the nucleation of mechanical twins is controlled by large local stresses which are set up in a crystal round inhomogeneities of various kinds. An examination is made of the stress fields round two types of inhomo and the kink band. It is shown t eneity arising during plastic def
