  Volovik and Kopnin make two seperate points regarding our recent paper (S. H.
Simon and P. A. Lee, PRL 78, 1548 (1997); cond-mat/9611133). First they note
that the scaling regime we address in our paper is limited by the curvature of
the Fermi surface, and secondly they note that the crossover scale derived in
our paper is incorrect. These points are valid and are discussed in this reply.
With the exception of the incorrectly predicted crossover scale, the results of
our paper remain unchanged.
