78 INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



pulsations continue quite rapid. On May 1 the temperature and 

 pulsations are normal. 



At the commencement of the preservative period there is a tendency 

 manifested, as in the fore period, to a temperature slightly above the 

 normal, though not sufficient^ so to indicate any very marked febrile 

 disturbance. On May 6 there is a marked increase in the frequency of 

 the pulsation, which is ascribed to the fact that, being a member of the 

 District Militia, No. '6 was engaged in drilling for an hour and a half 

 previous to coming to dinner. This raised the pulsation to above 100, 

 the recorded observations being 126 and 106, respectively, before and 

 after dinner. There is also a slight febrile excitement, but nothing 

 of a marked character. No further departures from normal conditions 

 are noted until the 18th of May, when a slight headache develops, 

 which persists during all of the afternoon. This symptom disappears 

 on the following day, and all conditions then remain normal until the 

 29th, when there is a recurrence of the headache, which is especially 

 severe during the evening. This continues on May 30, the headache 

 persisting during the whole day, but has passed away on the follow- 

 ing day, and there is no recurrence of it during the remainder of the 

 preservative period. On the 20th of June, the end of the period, the 

 recorded temperatures are 98.4 and 98.8 F. and the pulsations 90 

 and 80, respectively. 



Normal conditions continue throughout the after period. At no 

 time during the whole series is there any tendency to diarrhea or any 

 disturbance of the functions of the body which calls for any special 

 comment. 



The data in this case seem to indicate that the administration of the 

 boric acid during the period of fifty days has not produced any body 

 changes of a character sufficient to indicate any definite connection 

 between them and the preservative administered. 



No. 4E. C. S. 



In the beginning of the fore period, on the 24th of April, the 

 recorded data in the case of No. 4 are 98.7 and 98.5 F., for tempera- 

 ture, and 84 and 88 pulsations per minute, respectively, before and 

 after dinner. At the end of the fore period all the vital functions are 

 normal, and no departure therefrom of any significance has been noted. 

 It is observed, however, that on the last day of the fore period and 

 during the first few days of the preservative period there is an unusu- 

 ally large volume of urine voided. On May 5, the fourth day of the 

 preservative period, there is developed after breakfast a decided nausea, 

 followed by emesis, by which a large portion of the meal is lost. 

 Although the administration of the borax is continued, there is no 

 recurrence of the nausea and vomiting noted up to the 25th of May, 

 when the administration of the borax in this case is omitted, and on
