Since it. is well established now that there is preferential diffusion of atoms along dislocation lines in low-angle boundaries,(1>2$3' a question may arise as to the extent and manner in which randomly distributed dislocations may enhance the apparent volumetric diffusivity. In particular, one may

## Diffusivities of antimony and indium have been measured in specially deformed germanium specimens. The diffusivity of antimony has been measured (1) parallel to a high density array of parallel edge dislocations, (2) perpendicular to this array, and (3) in low dislocation, non-deformed material.

t If' the analysis is to be taken seriously, we can observe that there is one jog in the almost monotonic plot of activation energy as a function of temperature. At this jog, there is a shght upward jump in the plot which is also predicted by Hart.
