_D_e_t_a_i_l_s:

     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.
