<h3>Details</h3>


<p>Corbet et al. (1970) report a study of water voles (genus Arvicola)
in which the aim was to compare British populations of these
animals with those in Europe, to investigate whether more than
one species might be present in Britain. The original data consisted
of observations of the presence or absence of 13 characteristics
in about 300 water vole skulls arising from six British populations
and eight populations from the rest of Europe.
The data are the percentage incidence of the 13 characteristics
in each of the 14 samples of water vole skulls.
