58 INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



There are no abnormal symptoms of any kind exhibited at the begin- 

 ning of the fore period. On January 26 the feces are voided twice, 

 namely, at 11 a. m. and 4.30 p. m. The second movement is described 

 as somewhat soft. There are no further variations from normal con- 

 ditions observed or recorded during the fore period. 



On the first day of the preservative period the recorded tempera- 

 tures are 98.4 and 99 F. and the pulsations 76 and 80, respectively, 

 before and after dinner. On this day there are also two movements 

 of -the bowels, and the feces in both instances are recorded as very 

 soft. On the 29th the feces were voided three times, namely, at 8.45 

 a. m., 5 p. m., and 7.30 p. m. The first and second movements are 

 described as soft, and the third as very soft, indicating incipient diar- 

 rhea. There is no febrile disturbance, however, and no further 

 departure from normal. The diarrheal symptoms vanish on the fol- 

 lowing day. On February 1, the first day of the second subperiod of 

 the preservative period, a slight headache is noted, and recurrence of 

 the diarrheal symptoms the second movement of the bowels being 

 described as semiliquid. The diarrheal symptoms disappear on the 

 following day, "but a light headache continues. On February 3 the 

 feces are voided twice, and the second movement is described as very 

 soft; the headache continues. The symptoms of diarrhea and head- 

 ache disappear on the following day, the last of the second subperiod. 

 On the 7th, near the end of the third subperiod, there is a very severe 

 headache in the morning, becoming lighter in the afternoon, but no 

 further departure from normal conditions. A distinct febrile move- 

 ment is indicated on the 10th, on which day 4 grams of boric acid are 

 administered, the recorded temperatures being 98.5 and 98.7 F., 

 and the pulsations 80 and 86. The loss of appetite becomes so pro- 

 nounced that no breakfast can be eaten on the 10th, there is a severe 

 headache in the morning, becoming lighter in the afternoon, and 

 the subject discloses marked symptoms of indigestion and ill health. 

 On the llth, although no boric acid is given, the headache per- 

 sists during the whole day. There is, however, no further tendency 

 toward diarrhea, although some slight febrile tendencies are mani- 

 fest. The patient is in a condition unfit for further observations. It 

 is quite probable that the loss of appetite, with its attendant symptoms 

 and the headache, is due to the action of the preservative. It is, 

 however, not evident that the slight diarrhea manifest at times is due 

 to this cause, since it disappears during the latter part of the observa- 

 tion period, although the amounts of boric acid are increased.
