SALICYLIC ACID AND SALIC YLATES. 727 



In the case of Nos. 11 and 12 receiving sodium salicylate the aver- 

 age acidity for the fore period is represented by 34.0, for the pre- 

 servative period by 33.6, and for the after period by 36.2, showing a 

 tendency to decrease the acidity. . 



The percentage of cases in which albumin was found in the fore 

 period is 25, in the preservative period 36, and in the after period 30. 

 It appears from these data that the preservative distinctly favored the 

 formation of traces of albumin in the urine, the result being much 

 more marked, however, when the salicylic acid was administered than 

 in the case of the sodium salicylate.
