     A data frame with 47 observations on 6 variables, each

_D_e_s_c_r_i_p_t_i_o_n:

     (paraphrasing Mosteller and Tukey):  Switzerland, in
     1888, was entering a  period known as the ``demographic
     transition''; i.e., its fertility was beginning to fall
     from the high level typical of underdeveloped coun-
     tries.

     The data collected are for 47 seven French-speaking
     ``provinces'' at about 1888.

     Here, all variables are scaled to [0,100], where in the
     original, all but `"Catholic"' were scaled to [0,1].
