72 INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



of the fore period. On the last day of the fore period a sore throat 

 develops, but it has produced at this time no febrile excitement nor 

 interference with the appetite nor with the functions of the body. 



The soreness in the throat and the cold attending it still persist on 

 March 29. The third day of the preservative period, March 30, the 

 cold shows a very decided improvement, and disappears entirely with 

 the beginning of April. At the commencement of the second sub- 

 period, April 1, slight pains in the stomach are developed in this case, 

 which last about thirty minutes after meals. These pains, however, 

 are not repeated to any extent worthy of note on the following days. 

 Headache is noted on April 7, about the middle of the third subperiod, 

 but up to this time there has been no notable change in either tem- 

 perature or rate of pulsation. The functions of the body continue 

 to be discharged in a normal way during the fourth subperiod, though 

 there is some complaint of lack of appetite, and, occasionally, of heavy 

 feeling in the head, though not developed to the point of headache. 

 The appetite^ however, entirely fails on the last day of the fourth sub- 

 period, namely, April 14, although there is no febrile excitement or 

 other disturbance of the functions. This loss of appetite persists dur- 

 ing the 15th; in fact, the subject is so ill that he is not able to present 

 himself for examination and for the usual duties of the day. The loss 

 of appetite and general feeling of malaise have partial^ passed awa} f 

 on the 17th, and the subject is able to appear again for his meals. On 

 this date the boric acid has almost entirely disappeared from the urine. 

 There is a gradual improvement of the health up to and including the 

 last day of the after period, namely, April 22, when the recorded 

 observations are 98.6 and 98.6 F. for the temperature and 70 and 80 

 for the pulsations. 



The above data show a greater susceptibility of No. 10 to the influ- 

 ence of the preservative than has been exhibited by any of the forego- 

 ing members during this series, and it seems reasonable to attribute 

 the headache and feeling of malaise more or less directly to the admin- 

 istration of the preservative. The evidence, however, is not wholly 

 conclusive in this respect, though it is rather easy to exclude all other- 

 causes which may have produced the effects noted. The evidence, 

 while not entirely convincing, is corroborative in respect to the harmful 

 effect produced by the administration of the preservative. 



No. 11 J. S. C. 



Normal conditions are noted at the beginning of the fore period, 

 March 20, the recorded temperatures being 98.4 and 98.4 F. and the 

 pulsations 78 and 78, respectively, before and after dinner. There is 

 no notable departure from the normal state during the entire fore 

 period, the recorded data for March 27 being 98.6 and 98.6 F. for 

 temperature, and 72 and 78 for pulsations. On March 29 a slight
