  The contribution of nucleons to the quark condensate in nuclear matter
includes a piece of first order in $m_\pi$, arising from the contribution of
low-momentum virtual pions to the $\pi N$ sigma commutator. Chiral symmetry
requires that no term of this order appears in the $NN$ interaction. The mass
of a nucleon in matter thus cannot depend in any simple way on the quark
condensate alone. More generally, pieces of the quark condensate that arise
from low-momentum pions should not be associated with partial restoration of
chiral symmetry.
