Anisotropic magnetic properties of single crystals of (R, R', R",...)Ni$_2$Ge$_2$ (R = rare earth) solid solutions will be presented. Whereas the magnetic ordering temperatures and the paramagnetic $\Theta$'s broadly follow de Gennes scaling there are some systematic deviations from this oversimplfied trend. In this talk we will examine these deviations and also discuss the apparent absence of a spin-glass state induced by random magnetic anisotropy for the most highly mixed samples.
