772 INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



No. 3. W. F. H. , 



This subject entered the fore period in good condition with all 

 bodily functions normal. He had reported no sickness previous to 

 entering on this work and had never been very ill. While in college 

 he belonged to the rowing crew and sometimes had palpitation of the 

 heart after severe training. Occasionally he had a touch of heartburn, 

 but no serious indigestion. 



The first fore subperiod passed with the subject in good condition, 

 though his temperature was below normal, averaging 98 F., and 

 pulse quite high, being on an average 84 beats per minute. His 

 average body weight for this period was 63.54 kilograms. 



There was no change in the subject's condition during the second 

 fore subperiod. His temperature remained about the same, 98, 

 though on the first two days of the period it was normal. His pulse 

 was normal, averaging 74 beats per minute for the period. His aver- 

 age weight was 64.08 kilograms. 



He reported nothing wrong during the first preservative subperiod, 

 and seemed, from outward appearances, to stand the preservative 

 well. His average temperature for this period was 98.5 and average 

 pulse beats 81. The body weight averaged 64.18 kilograms. 



No. 3 began the second preservative subperiod with a temperature 

 decidedly subnormal, 97.7, taken before dinner, and pulsations 76. 

 His temperature after dinner of the same day was 98.6 and the body 

 weight 64.25 kilograms. On the evening of this day No. 3 became 

 very much alarmed. He reported violent palpitation of the heart, 

 with occasional loss of a beat at 10.30 p. m. of this day, which was 

 directly brought about by a brisk walk for half a block to catch a 

 car. He also experienced a sensation of giddiness and blurred vision 

 and difficulty of breathing. These symptoms lasted during the 

 night, and at 9 a. m. the next day his pulse was beating 120 per 

 minute. In the afternoon he had an attack of indigestion, some 

 headache, and continued dizziness. 



At 5.30 p. m. of this day his temperature was normal, 98.4, and 

 pulse beats 76 per minute. The body weight was 64 kilograms. 

 During the remainder of this period the indigestion evidently con- 

 tinued, as he experienced eructations of gas and occasionally belched 

 a mouthful of food. He also had pain in the abdomen and over the 

 left side and sensations of dizziness. His temperature and pulse 

 were quite variable, registering 98.6 on February 19 and pulsations 

 80. On February 20, the last day of the second subperiod, his tem- 

 perature is reported as 97.9 and pulsations 68. The average body 

 weight for this subperiod is practically the same as for the previous 

 one, 64.19 kilograms. 



The third preservative subperiod began February 21, and a tem- 

 perature, before dinner, of 98.9 F. and a pulse of 72 are recorded.
