66 INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



On March 12, the beginning of the after period, the temperature 

 and pulsations are normal. A slight headache, however, still persists. 

 The headache has disappeared on the 13th, the second day of the after 

 period. On the third day of the after period a slight febrile disturb- 

 ance is developed and a recurrence of the tired feeling is experienced. 

 Practically normal conditions supervene until the 17th, when there 

 is again a recurrence of the tired feeling and a very slight headache. 

 This slight indisposition continues also on the 18th. On the 19th, 

 which is the last day of the after period, the pulsations and tempera- 

 ture are practically normal, but No. 3 describes himself as not feeling 

 quite up to the standard and as having slight pains in the stomach. 



The data in the case of. No. 3 are also not quite distinctive. The 

 headache and general feeling of malaise manifested during the pre- 

 servative- period might be attributed to the cold or to some incidental 

 disease, but they appear also to be due, at least in part, to the adminis- 

 tration of the boric acid, although these disturbances continue, in 

 a less marked degree, during a part of the after period. It is, of course, 

 reasonable to suppose that such disturbances would continue for a 

 short time during the after period, but in this instance they persist 

 to a certain extent to the close of that period. It is barely possible 

 that the effects of the boric acid may have continued during this whole 

 time, but in the light of other experience this is not likely. The data, 

 therefore, obtained by these observations are not to be too positively 

 interpreted. 



No. 4E. C. S.a 



The first complete observations on No. 4 are made on February 21, 

 when there appears to be a slight febrile disturbance, the recorded 

 temperatures being 99.5 and 100 F. and the pulsations 72 and 72 per 

 minute, respectively, before and after dinner. On February 23 there 

 are two movements of the bowels instead of one as usual, and there 

 is still a slight febrile excitement, though not at all well marked. On 

 the last day of the fore period, February 27, the recorded data are 

 temperature 97.5 and 98 F. and pulsations 68 and 75, respectively. 

 The ftrst record for temperature is probably due to an error of obser- 

 vation of 1 in the reading of the thermometer. 



The first day of the preservative period exhibits no abnormal data 

 of any description. Two movements of the bowels are recorded on 

 March 2, the first marked as soft and the second as very soft, but this 

 is not pronounced enough to be regarded as even an intimation of 

 diarrhea. The second movement on the 4th of March is extremely 

 watery and partakes of the nature of a diarrheal discharge, with pains 

 and burning sensation in the intestines. At 1.30 p. m. 450 cc of 

 cloudy urine are voided, forming immediately a white precipitate. A 



E. C. S. takes the place of W. L. D. (No. 4 of Series I), who withdrew from the 

 experiment at the end of Series I.
