Variation in parameter E, length of mandible plus incisor, in Crocidura from various sites. 20,9 21,3 flavescens other parameters, indicates real change must also have been taking place. In particular, the length of M!_3, which has low coefficients of variation (Table 33), shows this to be the case. Of some interest, within the fluctuations, is the fact that levels DGL1 and DGL2 indicate a reverse trend which suggests a cooler period at the top of the sequence. In general, the differences between means of one population and those of preceding or succeeding populations are not statistically significant. This would suggest that the rate of change was normally relatively slow. On at least two occasions, however, there would appear to have been an increase in the rate of change. Given the one-sided hypothesis that successively younger levels in the postglacial period should contain populations of smaller individuals, the differ- ences between levels BRL6 and BRL5, and levels BLD3 and BLD2A are significant (Table 34). In both cases this represents quite rapid change over.
