respectively. Normal conditions also prevail on March 2. A slight 

 febrile disturbance is again marked on March 3. No marked symp- 

 toms of an abnormal nature are developed until the Tth of March, at 

 the end of the 2-gram preservative period. On this day No. 6 suffers 

 with severe pains in the stomach after breakfast. These pains pass 

 away during the morning, but return again at 2 p. m. after luncheon 

 and at 6 p. m. after dinner. Headache persists during the entire day. 

 Headache also persists during the 8th. On the 9th the headache is 

 described as still persisting, with pains in the bowels which at times 

 a*re very violent. No. 6 suffers again somewhat from a cold, although 

 the increase in temperature is only one-half degree, and takes 4 grains 

 of quinine. Headache persists during the 10th, with pains in the back 

 and a burning sensation in the face. There is no fever, however, dur- 

 ing the 10th, and no tendency to diarrhea, but rather to the opposite 

 condition. 



Constipation is well marked on March 11, no passage of the bowels 

 being recorded, and the headache continues. The headache persists 

 'also, but with less intensity, on the 12th, although this is the first day 

 of the after period. On the 13th the headache has disappeared, and 

 the boric acid has practically disappeared from the urine. On March 

 17 the appetite, which has been very much deranged during the pre- 

 servative period, is reported as again good, and No. 12 describes him- 

 self as feeling normal. No further variations in the normal conditions 

 appear during the remaining portion of the after period, the data 

 recorded for the 19th of March being for temperature 98.8 and 

 98.8 F. and the pulsations 76 and 78. 



These data again point with considerable significance to the disturbing 

 influences of the boric acid upon the body functions. It seems rather 

 clearly indicated that the headache, malaise, and pains in the intestines 

 experienced during the preservative period in this case are due to the 

 administered preservative. It is true that on one day No. 6 suffered 

 from a slight cold and took 4 grains of quinine, but the fact that the 

 headaches and pains were not manifested during the fore period, that 

 they appeared with increasing intensity as the amount of boric acid was 

 increased during the preservative period, and gradually disappeared 

 during the after period, as the boric acid disappeared from the urine, 

 indicates with a marked degree of conviction that the disturbances 

 complained of were caused* in part at least, by the preservative 

 administered.

No. 7 E. R. M. 



The fore period of the fourth series begins on March 20. The 

 record for No. 7 on this day for temperature is 98.6 and 98.8 F. 

 and pulsations 80 and 80, respectively. Apparently all the body f unc-
