500 INFLUENCE OF FOOD PKESEKVATIVES ON HEALTH. 



better, a pain in the region of the kidneys developed. This did not 

 persist, however, and on the following day No. 9 was in good condi- 

 tion. Some pain in the eyes was noticed on November 17. 



The fifth preservative subperiod found No. 9 with exactly the same 

 weight as at the beginning of the fore period, namely, 62.10 kilo- 

 grams. He complained of coughing slightly at night and of some 

 nocturnal perspiration, but this was of an entirely unimportant 

 character. 



At the beginning of the sixth preservative subperiod No. 9 weighed 

 62.70 kilograms and was in excellent condition, feeling better even 

 than at any period during the progress of the experiment. The appe- 

 tite was excellent, and on November 26 the subject felt hungry after 

 dinner. 



At the end of the preservative period, namely, November 27, No. 9 

 weighed 62.40 kilograms and was feeling in excellent condition. The 

 average weight for the entire preservative period was 62.22 kilograms, 

 as compared with 62.25, the average of the fore period. 



The beginning of the after period 'found No. 9 in excellent condi- 

 tion, and he passed through the entire after period without any inci- 

 dent worthy of attention, save that he complained of hunger on every 

 day of the first subperiod, but made no such complaint during the 

 second subperiod. 



The weight of No. 9 at the end of the after period was 62.30 kilo- 

 grams, temperature and pulse normal, and all the functions of the 

 body apparently properly discharged. This case is quite in contrast 

 with most of the others. First, in the fact that no unpleasant symp- 

 toms were observed even with the largest doses of salicylic acid; and, 

 second, that the feeling of hunger, which was so commonly manifested 

 during the first periods of the administration of the salicylic acid in 

 the other cases, was not noticed in this, but the symptoms of hunger 

 developed decidedly after the cessation of the doses of the salicylic 

 acid. 



Judged, therefore, simply by the medical history no unfavorable 

 S}^mptoms of any kind were noticed during the whole course of 



observation. 



No. 10. R. D. D. 



No. 10 began the fore period weighing 57.10 kilograms. Physical 

 examination revealed no defects in any of the organs of the body. 

 There had been no previous disease of any consequence within a year 

 and no tendency to any organic disturbances was found. The fore 

 period passed without any incident worthy of record. The tempera- 

 ture and pulse remained normal during the entire time. At the close 

 of the fore period the weight of No. 10 was 56.99 kilograms and all 

 the functions of the body were normally discharged. The average 

 weight for the entire fore period was 56.91 kilograms.
