62 INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



day, namely, a temperature of 99.9 F. , after dinner, with a pulsa- 

 tion of 100, is doubtless due to the cold rather than to the action 

 of the boric acid. On the 3d the headache is described as having 

 been very severe during the night, but not so severe during the day. 

 There are also two movements of the bowels, the first dark and soft 

 and the second dark and very soft. The febrile excitement also con- 

 tinues, the recorded temperatures being 99.6 and 99.7 F. and the 

 pulsations 96 and 100 before and after dinner. The conditions 

 described continue during the 4th of February, the last day of the 

 second subperiod. Under the continued administration of borax 

 these symptoms are very much accentuated, and No. 12 is in such a 

 condition on the 6th of February that the further administration of 

 boric acid is discontinued. On February 16 No. 12 has sufficiently 

 recovered to take some of the preservative again, but the interrup- 

 tions in the observation due to his illness render the further study of 

 his case, as a whole, in connection with the series, of but little value 

 for the supplementary period. The amount of boric acid given on the 

 16th is 1 gram; on the 17th, 2 grams; on the 18th, 3 grams; on the 

 19th, 4 grams, and on the 20th, 5 grams. Nos. 8, 9, and 11 also take 

 part in this special test. No. 12 is then excused from further attend- 

 ance, his condition being such as to render further consideration of the 

 case undesirable. In this, as in the three other cases, the administra- 

 tion of the boric acid may be associated with the production of the 

 headache, malaise, nausea, and general distress from which the patient 

 suffers, but there are also symptoms of grippe. The preservative 

 appears to cause no trouble whatever, at least any that can be noted, 

 by inducing diarrheal symptoms or any marked increase in the vol- 

 ume of the urine. 



SERIES III. 



No. 1J. N. 



The observed data of No. 1 on February 19, the first day of the 

 fore period of Series III, are temperature 98.1 and 98.4 F. and 

 pulsations 62 and 69 beats per minute, respectively, before and after 

 dinner. A light febrile disturbance is noticed on February 22, the 

 thermometer registering 98.6 and 99 F. A similar slight increase 

 of temperature is also noted on the 26th, but is not of a character to 

 incite apprehension. The last day of the fore period the temperature 

 registered is 98.5 and 98.8 F. and the pulsations are 57 and 66, 

 respective!}^ before and after dinner. There are no departures of any 

 marked importance from the normal state other than the slight febrile 

 excitement mentioned during the fore period. 



The first day of the preservative period, namely, February 28, the 

 data registered are 98.7 and 98.5 F. for temperature and 78 and 75 

 for pulsations. On this day there is a second movement of the bowels, 

 and the feces are soft and of a light color. A similar record is made
