Analysis of the volume relaxation data of Hara and Suetoshi shows that Narayanaswamy's model of structural relaxation is successful within 100 degrees of T//g. If the temperature dependence of the relaxation time is represented by the Adam-Gibbs equation, physically reasonable fitting parameters are obtained. However, relaxation at low temperatures (T//g - 200 degree C) is unexpectedly fast. Several modifications to the standard theory are considered, but none brings the theory into complete agreement with data.
