An opportunity was afforded to compare the test for syphilis recently proposed by Hinton with the Kahn reaction, which is the standard method in these laboratories. The technic of the two tests was carried out strictly in accordance with the directions of the respective authors.1 Dr. Hinton furnished the antigen for his test. Table 1 summarizes the results given by the two methods with 748 serums. Of this number, 363 were positive with the Kahn test and 299 were positive with the Hinton test. Sixty-nine serums were positive with the Kahn and negative with the Hinton test, and five were positive with the Hinton and negative with the Kahn test.
An attempt was made to determine the clinical histories of the seventy-four cases which showed divergent results. Data were obtained on only forty-four of these cases, which are presented in table 2. It is evident from this table that
