IN a recent communication, Stott and Stacey1 report on a "crucial experiment" from which they conclude: "This excellent agreement between the dip and the directions of artificial thermoremanent magnetization of the stressed and unstressed rocks indicates that large systematic errors due to magnetostriction are most improbable in igneous rocks of types normally used for pal??omagnetic work". This experiment was intended to test the proposals2 and measurements3 bearing on the role of magnetostriction in rock magnetism. We present here our reasons for believing that the experiment was not crucial and that the conclusion is not justified. ?? 1959 Nature Publishing Group.
