     Charles Darwin conducted an experiment to examine the superiority
     of cross-fertilized plants over self-fertilized plants.  15 pairs
     of plants were used. Each pair consisted of one cross-fertilized
     plant and one self-fertilized plant which germinated at the same
     time and grew in the same pot. The plants were measured at a fixed
     time after planting and the difference in heights between the
     cross- and self-fertilized plants are recorded in eighths of an
     inch.
