        By using data previously obtained for Ni, curves are given that establish a relation between the magnetization σ, the field H, and the absolute temperature T.  Systematic divergences from the relation H_m=nσ, where n is a constant, are ascribed to an intra-atomic change by which Ni passes from 3 to 8 magnetons.
