Their experiments were conducted with an antigen of Pasteurella pestis, horse antipest serum, guinea pig complement, and an antirabbit hemolytic system with adequate controls. Indeed their technique was wonderfully correct in all essential details. Curiously enough, however, the possible value of this discovery in the serum diagnosis of infectious diseases escaped their attention. But Widal and LeSourd2 promptly employed this test in the diagnosis of typhoid, which was soon followed by its application in the identification and differentiation of blood stains by Gengou and Neisser and Sachs, in typhoid by Wassermann and Bruck, in tuberculosis by Wassermann and Sachs, in swine erysipelas by Citron,
