540 INFLUENCE OF FOOD PKESEEVATIVES ON HEALTH. 



No. 2, 



A trace of albumin occurs in the urine of No. 2 during the whole 

 period of observation. The reaction of the urine is arnphoteric in the 

 fore period, and it becomes acid in the preservative period. 



No albumin is found in the urine of No. 3 during any period of 

 observation. The acidity of the urine increases during the adminis- 

 tration of the salicylic acid. 



No, 4. 



The observations in the case of No. 4 are practically the same as in 

 the case of No. 3. 



No. 5. 



There appears to be no definite change produced in the case of No. 5 

 by the action of the salicylic acid either upon the small quantity of 

 albumin present or upon the relative acidity. The urine is strongly 

 acid during the fore period, and also strongly acid during the preserva- 

 tive period. 



No. 6. 



The data in the case of No. 6 indicate practically the same absence 

 of effect as those of No. 5. 



No. 7. 



No albumin is observed in the case of No. 7 at any time during the 

 observation. The reaction of the urine is alternately acid and ampho- 

 teric, and the preservative appears to have had no influence in deter- 

 mining the condition. 



No. 8. 



No albumin appears in the case of the urine of No. 8 at any time. 

 The reaction of the urine under the influence of the preservative 

 becomes amphoteric. In this case there appears to have been a very 

 slight influence on the part of the drug administered to diminish the 

 acidity of the urine and to produce an amphoteric condition thereof. 



No. 9. 



No albumin is present in the urine at any time of the observation. 

 The reaction of the urine is amphoteric at one time during the fore 

 period, but acid the rest of the time. 



No. 10. 



No albumin is found in this case at any time. During the adminis- 

 tration of the salicylic acid the reaction of the urine changed from 

 amphoteric to strongly acid. The apparent effect in this case is 

 exactly the opposite of that produced in the case of No. 8.
