776 INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



During the fourth preservative subperiod No. 4 received 4 grams of 

 sodium sulphite per day (equivalent to 1.020 grams SO 2 ). On the 

 first two days of the period he records that he felt normal in every 

 way. His temperature was subnormal on the first day, 98 F., but 

 normal, 98.6, on the second day, and the pulse was normal. On the 

 third day he developed a slight headache and some fever; temperature 

 99.4, pulsations 78. The headache and fever continued, though 

 slight, on the fourth day; temperature 99.5 F. and pulsations 78. 

 On the fifth day the headache still continued, though the temperature 

 had dropped back to normal, 98.6 F., pulsations 74. The average 

 body weight was 62.40 kilograms for the last subperiod and for the 

 entire preservative period it was 62.73 kilograms. 



He reported himself as normal throughout the first after subperiod. 

 His temperature, however, was quite below normal, averaging 97.9 

 F. for the period, pulse normal. The average weight was 61.91 

 kilograms. 



The condition was normal throughout the second after subperiod, 

 temperature and pulse normal, average weight 61.85 kilograms. 

 The average for the entire after period was 61.89 kilograms. 



No. 4 showed less effects from the preservative than any other 

 members of the class, though starting under rather unfavorable 

 conditions in the fore period. The symptoms developed in the fourth 

 preservative subperiod differ from those of others in absence of 

 pains in lower abdomen and intestines and sensations of dizziness; 

 a headache developed accompanied with a slight and quickly rising 

 fever, which disappeared as quickly as it appeared. 



The urine was normal throughout the whole experiment as shown 

 by the clinical examination. 



No. 5.C. C. P. 



This subject entered at the beginning of the second fore subperiod, 

 the original No. 5 having been excused. His medical history pre- 

 vious to entering this experiment was fairly good. He had been 

 No. 3 in Series VI on salicylic acid, and while he was not an ideal 

 subject for such experimental work as concerned his own observations, 

 his analytical data are correct. He was quite young and easily 

 influenced by surroundings. Further, he was negligent in caring for 

 his own bodily functions and in the previous experiment was very 

 constipated, which condition to some extent obtained during this 

 series. 



During the relaxation period the subject had had a slight cold the 

 greater part of the time. An examination of his heart revealed a 

 very quick action. 



In the fore period his temperature and pulse were high throughout, 

 averaging 99.1 F. and 93, respectively. He reported a headache
