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

     enzyme : The data comprise independent measurement of enzyme
     activity in the blood of 245 individuals. The data were analysed
     by Bechker _at al._ (1993).

     brains : the brain size, 'brain', and body weight, 'body', for 28
     differnt animals.
