He would then graph the sum~ xf (x) cumulated from the bottom as ordinate against the sum~ x cumulated from the bottom as abscissa to obtain Gini's curve of concentration or the Lorenz curve (Kendall and Stuart, 1958, 1, p. 48). 3 6. Bradford, however, cumulated from the other end and produced figures analogous to those of columns C and D in Tables 1 and 2. He then remarked that if we put C on a logarithmic scale, as given in column E, and graph D
