%X The recent development of methods for the numerical solution of the diffusion equation when the diffusivity is concentration-dependent enables' certain phenomena, previously not amenable to quantitative analysis or ineffectively described by empirical functions, to be studied more fully. This communication points out an example of concentration-dependent diffusion which does not appear to have previously received attention.
