The recent suggestion "that Harper-Dorn creep as a unique dislocation mechanism with Newtonian viscosity may not exist" is shown to rest on an incomplete application of the conditions under which Harper-Dorn creep is expected to be the dominant mechanism of plastic deformation.

## A~t~et-Existing theories of Harper-Dorn creep rely on the adaption that, under conditions where Harper-Dorn creep is observed, the dislocation density rapidly achieves a characteristic value which is independent of the method of preparation of the sample, of the applied stress, and of the exten
