780 INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



his believing that he was going to be very ill, and after February 27 

 of this period the observation of this subject ceases, and the data are 

 therefore excluded from the general summaries. A careful examina- 

 tion of the urine during the time that this subject complained of 

 suffering so intensely with his kidneys revealed nothing abnormal. 



Notwithstanding the exaggeration of his symptoms by this subject 

 it is safe to conclude that the preservative did, as in other cases, pro- 

 duce headache, a sensation of dizziness, some loss of appetite, and 

 slight indigestion, though the body weight remained fairly constant. 



No. 8.W. C. L. 



This subject presents a very interesting case. He was very con- 

 scientious, regular in his habits, and gave the strictest attention to 

 every detail. His personal idiosyncrasies and their possible effect on 

 the metabolic processes must, however, be considered. He regu- 

 larly took a prescribed laxative throughout the observation and 

 drank a large quantity of water (a quart at a time was no unusual 

 amount) on rising and, at other times during the day, and in addi- 

 tion drank a cup of hot water at meal times. 



He had suffered somewhat from a cold before beginning the fore 

 period. The heart action and other body functions were normal. 

 During the fore period No. 8 felt that he was taking cold, and took

 average weight being 61.63 kilograms. 



On February 16, the first day of the second preservative subperiod, 

 No. 8 became dizzy and nauseated. This feeling came on while he 

 was smoking his usual cigar, and may have been due to that, though 

 he stated it was not a strong cigar. He felt all right, however, the 

 next day, and also on the 18th. On the 19th he had a slight head- 

 ache and a feeling of depression; his temperature and pulse, however, 

 were normal. He 'complained on the last day of this subperiod of 

 headache and eyes aching and a " grippe-like " feeling, which largely 

 disappeared after he had. completed his wheel ride before dinner. 

 The average weight for the period was 61.99 kilograms, a slight gain 

 over the preceding period. 



During the third preservative subperiod No. 8 had a great variety 

 of symptoms, some of which seemed to be irrelevant. On the first day 

 he complained of a depressed and drowsy feeling, though he had 

 plenty of exercise; at other times during the period he complained 

 of headache, occasional loss of appetite, and drowsiness. On Feb-
