Some experiments are described in which a medium sand was deposited on a sloping bed in still water in the laboratory. Estimates of the grain-fabric orientation of the deposits were obtained from measurements of the anisotropy of their magnetic susceptibility. It was found that an anisotropy of susceptibility could be produced, which was very similar to that produced by deposition from running water. The possibility is discussed that grain-fabric orientation in rocks may sometimes be produced in a similar manner and that confusion may arise if the presence of depositional slopes is not recognized.
