The predominant slip direction of crystalline mercury is not the closest‐packed direction. In order to explain this and related observations, a geometrical analysis has been made of the types of dislocation which may be present in the mercury structure. Two approaches have been adopted. The first of these is based on the well‐established dislocation geometry of face‐centred cubic crystals; it does not lead to an adequate understanding of the experimental results. A satisfactory explanation of the observations is obtained, however, in the second approach, which considers the stacking sequence of the mercury slip planes. Some general implications of the results are discussed.
