Graphic representation of areas described by the interaction of a single antiserum (leghorn) with each of several antigens. The turbidity readings for the varying dilutions are plotted along the abscissa. Tube number 1 is a dilution of one part of protein to parts of saline; tube number 2 is a dilution of one part of protein to of saline; tube number 3 a dilution of one part to 125; each succeeding tube possessing one-half of the concentration of protein of its predecessor. Note the bimodality, or polymodality, of these curves which is typical of reactions in which sera serve as antigens. (Reprinted by permission from DeFalco, 1941, Proc. Soc. Exper.
