770 INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



The third preservative subperiod was characterized by pains in 

 the stomach throughout the period, and on the first day of the 

 period the subject complained of being weak and feeling chilly. 

 His temperature for this period ranged from 98.2 to 98.6, and his 

 pulse was somewhat varied, ranging from 55 to 70 beats per minute. 

 The body weight, however, showed a slight gain, 68.10 kilograms 

 being recorded on the first day and 69.20 on the last day of the 

 period. The average weight for this subperiod was 68.64 kilograms. 



During the first part of the fourth preservative subperiod No. 1 

 still complained of abdominal pains, but by the end of the period the 

 subject reported himself as feeling " normal" and with no " symp- 

 toms." The temperature and pulse were normal during this sub- 

 period, the average body weight being 68.94 kilograms. The average 

 weight for the entire preservative period was 68.58 kilograms. 



During the preservative period No. 1 developed a very minute 

 trace of albumin in his urine; the microscopical examination, how- 

 ever, did not show any marked change. 



The preservative period, as a whole, had quite a noticeable effect 

 on this subject, though he was loath to admit it. His general 

 appearance was below normal and he seemed much depressed, but 

 improved in the last preservative subperiod. 



In the after period no symptoms are recorded; the temperature 

 remained normal, 98.4 throughout, pulse normal, and the whole 

 general appearance somewhat improved. 



The average weight for the first after subperiod was 68.48 kilo- 

 grams, for the second after subperiod 68.76 kilograms, and for the 

 entire after period 68.62 kilograms. 



No. 2.W. P. 



This subject began the fore period with a temperature of 98.1, 

 pulse 69 beats per minute, and a body weight of 70.72 kilograms. 

 The only point of note during the fore period is the uniformly low 

 temperature and the fact that the pulse is somewhat lower during 

 the second fore subperiod, the average for the five days being 62. 

 No. 2 had had no previous sickness and was in good condition during 

 the fore period. The average body weight for the first subperiod 

 was 70.31 kilograms, for the second subperiod 70.04, and for the 

 entire fore period 70.18 kilograms. A clinical examination of the 

 urine of No. 2 showed a slight albuminuria. 



No. 2 passed through the first preservative subperiod without 

 any apparent change, his temperature still remained subnormal, 

 pulsations were very constant, registering 59 and 60 throughout; his 

 average body weight was 69.94 kilograms. On the fourth day of 

 the second preservative subperiod he reported a feeling of dizziness 

 at times, which did not occur, however, on the succeeding day. His
