Discussion on “frequency” (Rushmore), Schenectady, N. Y., May 17, 1912. (see proceedings for June, 1912)

Samuel Sheldon: It is to be regretted that the author of this paper has seen fit to omit the unit costs which have been chosen for the ordinates of his curve-sheets and the unit capacities used for abscissas. Were these to be introduced, the value of the paper to the membership would be much enhanced. If commercial considerations compel their omission, information could at least be given as to whether suppressed zeros are to be associated with the axes of coordinates at their points of intersection. Such suppressed zeros are associated with the coordinates of the only figure whose units are designated.
