 SUMMARY FOR NINE MEN. 



THE URINE. 



The importance of a study of the urine in connection with the ascer- 

 tainment of any effects produced by the administration of salicylic 

 acid and other preservatives is evident without comment. In the fol- 

 lowing tables are given the results of the observations obtained on the 

 urine. The influence of any added preservative upon the volume of 

 the urine and the amount of solids therein is quite significant, and 

 these points were carefully studied. These studies were conducted 

 by F. C. Weber. 



VOLUME, SPECIFIC GRAVITY, AND TOTAL SOLIDS. 



The data given in Table VIII relating to the total solids in the urine 

 are calculated from the specific gravity, in harmony with the method 

 used in the borax experiment, by the factor 0.245. a 



INDIVIDUAL DATA. 

 NO. 1. 



The volume of the urine is decreased during the preservative period 

 and still further decreased in the after period. The specific gravity is 

 increased in the preservative period and still further increased, by a 

 very slight amount, in the after period. The increase in specific 

 gravity is greater in proportion than the decrease in volume, since the 

 weight of the total solids excreted is greater in the preservative period 

 and still further increased, by a slight amount, in the after period.
