Abstract
We try to explain the differences between the concepts of stratifiable space and -metrizable space. In particular, we give a characterization of -metrizable spaces which is modelled on Chigogidze's characterization. Moreover, we present a -metric for the Niemytzki plane, using the properties of the Euclidean metric.
