  We correct a statement of a theorem on characterisation of the (c)-regularity
we gave in Topology 37 (1998), 45--62. This theorem was used in the paper in
the proof of two theorems on the (c)-regular stratification. In this note we
give a weaker version of the theorem as an alternative lemma which ensures the
(c)-regularity condition and turn to be sufficient for the proof of the
theorems.
