494 INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



patient felt that his appetite was satisfied with the usual rations. On 

 the 12th of November, the appetite still remaining normal, the subject 

 was not feeling well, having a slight tendency to diarrhea. The 

 beginning of the fourth preservative subperiod found the patient feel- 

 ing drowsy, but still with a normal appetite. No other abnormal 

 symptoms were developed during this subperiod. 



During the fifth preservative subperiod the patient remained in a 

 normal condition until the 20th of November, when symptoms of 

 indigestion or uneasiness in the region of the stomach appeared, but 

 the appetite was not noticeably disturbed. These feelings passed 

 away on the following day and the subject remained normal during 

 the rest of that period. During the sixth preservative subperiod the 

 patient continued normal and at the end of the preservative period 

 was in good condition, weighing 59.52 kilograms. The average weight 

 for the entire preservative period, however, was 59.71 kilograms, a 

 slight decrease as compared with the fore period. 



The patient was in good condition at the beginning of the after 

 period and no unfavorable symptoms of any kind were developed; 

 the appetite was normal and the food appeared to suit the demands of 

 the appetite. At the end of the after period the pulse and tempera- 

 ture were normal and the weight was 59.29 kilograms, that being also 

 the average for the entire period, thus showing a slight continued 



decrease in weight.

This subject began the fore period in normal condition as respects 

 both temperature and pulse and with a weight of 58.12 kilograms. 

 No unusual symptoms developed during the fore period excepting 

 perhaps a slight tendency to constipation. At the end of the fore 

 period the patient's condition remained normal but with a slight loss 

 of weight, which had fallen to 57.48 kilograms. The average weight 

 for the fore period, however, was somewhat higher, i. e., 58.06 kilo- 

 grams. 



During the preservative period the condition of the subject re- 

 mained normal without any notable symptoms during the first and 

 second subperiods until the 5th of November, when complaint was 

 made of a feeling of hunger after the usual rations of the d&y had 

 been consumed. There was a gradual but not marked loss of weight, 

 and the subject continued to complain at times of leaving the table 

 very hungry. The appetite remained good during the third preserva- 

 tive subperiod, and on the 9th of November a slight cold in the head 

 developed without any marked increase in temperature. There was 

 a considerable fall in weight on that date, which was ascribed to a little 

 unusual exercise. A slight cold continued on the 10th of November, 

 but otherwise the subject was feeling well and the appetite was still keen,
