  1. 1. The water-insoluble plasmodial residues of P. lophurae appear to contain antigens which stimulate the formation of protective antibodies in the duckling.
  2. 2. The antigenicity of this material is increased by the addition of a bacterial toxin.
  3. 3. Certain features of the immunology of malaria are presented, and the hypothesis that the useful antigens are insoluble haptens is outlined.
