value of these findings and assuming that, in tuberculosis and in 

 typhoid, neutral sulfur is usually present in the urine, we examined 

 the histories of all the cases in which positive tests were obtained 

 by either method and thus eliminated these two diseases as the 

 cause of the appearance of neutral sulfur in the urine, with the 

 f ollowing results : 



As this summary shows, of 122 cases in which the history of 

 tuberculosis and typhoid were ruled out, 113 gave negative tests 

 by both methods. The 4 cases in which both diazo and Weiss 

 tests were positive were clinically cases of diabetes, Cholecystitis, 

 gangrene and pleural effusion. Whether in these conditions, the 

 findings for neutral sulfur are constant we cannot teil, for we had 

 only one case of each in this series. 



C omparisons of urinary findings with the results of the serum 

 test. Having thus ascertained the degree of efficiency of the tests 

 as compared with each other, and having found that the tests are 

 usually negative for cases where both typhoid and tuberculosis 

 are excluded, we proceeded to compare the findings of the urinary 

 examination with those of the serum test.
