56 INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



several days preceding 1 January 1 No. 4 felt that his head was not 

 clear, and on each morning on waking rather early he had more or less 

 headache. The symptoms in the case of No. 4 ma} 7 have been due to 

 the change in diet on the hygienic table, the ration containing rather 

 more meat than he has ordinarily eaten. The appearance of the rash, 

 itching, and other cuticular symptoms is incident to the disturbance 

 of the digestion and it seems rather clear in this case that the dis- 

 turbance is caused directly by the administration of the preservative. 

 The temperature was not taken during the severest period of suffering 

 in the afternoon, but the pulse was counted and found to be high on 

 the 1st of January, namely, 98 beats per minute. The recorded tem- 

 peratures, however, made late in the afternoon, show that the febrile 

 excitement had subsided, the temperatures being 98.1 and 98.4 F., 

 while the pulsations are rapid, namely, 96 per minute, both before 

 and after dinner. The recorded observations for the last day show 

 temperatures of 98.5 and 98.5 F., and pulsations of 84 and 84, respec- 

 tivety. Headache and nausea continued through the whole day, and 

 the patient experienced u a feeling of great oppression in the region of 

 the stomach." These symptoms of nausea, headache, and oppression 

 seem directly due to the administration of the preservative. On Jan- 

 uary 4 the recorded temperatures are 99 and 99 F. and the pulsa- 

 tions 84 and 88, respectively, and the symptoms of headache and nausea 

 are not so pronounced. There is still a slight febrile excitement on 

 the 5th, the temperature registering 99 and 99 F. at the two obser- 

 vations. Normal conditions are gradually restored, and on Januiry 

 8 the registered temperatures are 98.5 and 98.5 F. and the pulsa- 

 tions 76 and 76, respectively, and the headache and nausea have ceased. 

 On January 13, the last day of the after period, the recorded observa- 

 tions are 98.5 and 98.4 F. and the pulsations 76 and 76, respectively. 

 All unpleasant symptoms have passed away, and the patient appears 

 to be in a normal condition. During the entire time of this series of 

 observations there is no marked disturbance of the character of the 

 feces and no tendenc} 7 to diarrhea is observed. 



No. 5 R. V. F. 



The record of the temperature of No. 5 on the 9th of December is 

 98 and 98.3 F. and the pulsations 86 and 85 before and after dinner, 

 respectively. On the 16th there appealed to be a slight rise of tem- 

 perature, the readings of the thermometer being 98. 6 and 98.8 F. 

 and the pulsations 84 and 101, respectively. This slight febrile dis- 

 turbance is also manifest on the 17th. On the 18th it ,/s shown to be 

 passing away, the records of the thermometer being 986 and 98.6 F. 

 and the pulsations 88 and 96 before and after dinn/r, respectively. 

 There is no further abnormal development during th^fore period.
