#    The data records the average weight of the brain and body for
#    a number of mammal species.  
#
#    There are 62 rows of data.  The 3 data columns include:
#
#      I,  the index,
#      A1, the brain weight;
#      B,  the body weight.
#
#    We seek a model of the form:
#
#      B = A1 * X1.
