532 INFLUENCE OF FOOD PKESEKVATIVES ON HEALTH. 



In this case the volume of the urine is increased and the specific 

 gravity diminished in the preservative period. In the after period 

 the volume of the urine is considerably diminished below the fore 

 period, and its specific gravity is increased above that of the fore period 

 and also of the preservative period. The weight of the total solids 

 excreted is greater in the preservative period than in the fore period, 

 and this weight is still further increased in the after period. 



, No. 3. 



The data for No. 3 are somewhat fragmentary and show little change 

 in the volume of the urine during the three periods. The specific 

 gravity is slightly less in the preservative period, while in the after 

 period it rises a very little above that of the fore period. The quan- 

 tity of total solids is decreased during the preservative period, while 

 in the after period the quantity is the same as in the fore period. 



No. 4. 



In this case there is a slight increase in the volume of the urine in 

 the preservative period and a still further slight increase in the after 

 period. The specific gravity is high through all the periods, being 

 slightly greater in the preservative and again slightly increased in the 

 after period. The total quantity of solids excreted is greater in the 

 preservative period and continues to increase in the after period. 



No. 5. 



There is a slight increase in the total volume of the urine in the 

 preservative period and a greater increase in the after period. The 

 specific gravity is slightly higher in the preservative period and 

 slightly lower in the after period than in the fore period. The total 

 quantity of solid matter excreted in the urine is greater in the pre- 

 servative period and still somewhat greater in the after period. 



No. 6. 



There is a notable increase in the volume of the urine in the pre- 

 servative period, but this increase is only partially maintained in the 

 after period. The specific gravity of the urine is high and almost the 

 same in the fore and preservative periods and slightly higher in 

 the after period. The quantity of total solids excreted is notably 

 greater in the preservative period, with a slight loss in weight in the 



after period. 



No. 7. 



There is a notable increase in the volume of the urine in the pre- 

 servative period in this case, while in the after period the volume is 

 only slightly greater than in the fore period. The specific gravity of
