60 INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



even larger quantities of the preservative than those taken during this 

 period without reestablishing the pronounced symptoms described. 



No. 9E. B. D. 



The data recorded for No. 9 on January 21, near the beginning of 

 the fore period, are temperature 98.6 and 98.7 F. and pulsations 73 

 and 80 before and after dinner, respectively. On the 23d pronounced 

 symptoms of febrile disturbance are manifest, the recorded tempera- 

 tures being 99.1 and 99.2 F. and the pulsations 84 and 88, respec- 

 tively. A slight decrease of temperature is noted on the following 

 day, but the quickness of the pulse is maintained. A marked increase 

 and febrile excitement are noted on the 25th, the temperatures recorded 

 being 99.3 and 99.4 F. and the pulsations 92 and 90, respectively. 

 The temperature is still higher on the 26th, being 100 and 100.1 F. 

 and the pulsations 84 and 94, respectively, before and after dinner. 

 Symptoms of grippe, so called, are manifest, complicated with a very 

 bad cold already two days old, with a severe headache during the pre- 

 ceding night, accompanied by neuralgia in the head which is intermit- 

 tent. The illness is so pronounced as to prevent the attendance of 

 No. 9 at all on the 28th. On the 29th the cold is found to be somewhat 

 better and the temperature is lower, the feces being hard and deeply 

 colored. The symptoms of grippe have so developed on the 29th that 

 No. 9 is dropped from the table, as it is evident that he is in no con- 

 dition to begin any experiments with preservatives in the food. 



No. 10 W. J. J. 



The recorded observations of No. 10 on January 21, the third day 

 of the series, are temperature 98.6 and 98.8 F. and pulsations 80 

 and 80, respectively. No notable variations from normal conditions 

 are apparent during the continuance of the fore period, save on the 

 last day, January 27, when there are two movements of the bowels. 



During the first preservative subperiod no marked variations in the 

 vital data are noticed. The data continue practically normal, with 

 very slight variations, during the second subperiod also, which includes 

 the days from February 1 to February 4, inclusive. The third sub- 

 period passes also without any notable variation from the normal con- 

 ditions. On February 9 and 10, 4 grams of boric acid a day are given 

 to No. 10. On the 10th a persistent dull headache develops. There 

 is a slight increase in the temperature, the record being 98.8 and 

 98.6 F., and also a slightly increased rate of pulsation, the data being 

 80 and 92, respectively, before and after dinner. On the following 

 day very marked effects are noticed a failure of appetite, general 

 feeling of malaise, and discomfort. The effects, however, in the case 

 of No. 10 are not nearly so marked as in the other two cases noted, 

 but they are distinct and show marked disturbances with this quantity
