    {Duplicate proportion} or {ratio} (Math.), the proportion or
       ratio of squares. Thus, in geometrical proportion, the
       first term to the third is said to be in a duplicate ratio
       of the first to the second, or as its square is to the
       square of the second. Thus, in 2, 4, 8, 16, the ratio of 2

       2 is to the square of 4.
