BORIC ACID AND BORAX. 71 



much as four-tenths of 1 per cent. This may be due, however, to 

 imperfect registration or observation of the thermometer, but is not 

 sufficient to cause any comment. 



The preservative period is commenced with all of the body functions 

 apparently in good condition, but still with a tendency to a tempera- 

 ture below the normal although this is not of a marked nature. On 

 March 31, at the end of the first subperiod, the pulsations drop to 56 

 and 60 per minute and the recorded temperatures are slightly below 

 98 F. This condition passes away, however, on April 3, when the 

 temperature and pulsation are again restored to the normal. There 

 is a slight tendency to constipation, which is particularly marked on 

 April 3, when no movement of the bowels occurred. The third sub- 

 period, April 5-9, passes without any marked variation, except that 

 on the 9th there are two movements of the bowels, instead of one as is 

 usual. This second movement, however, is not of a nature to indicate 

 any tendency to diarrhea. There is a marked tendency to frequent 

 urination developed during the latter part of the preservative period, 

 the urine on the 12th being voided ten times and the total volume 

 secreted being unusually large 1,695 cc. Toward the close of the 

 fourth subperiod well-defined symptoms of continuing headache are 

 developed, which are very marked on April 14, the last day of the 

 fourth subperiod. The temperature and pulse, however, remain prac- 

 tically normal, the recorded observations being 98.1 F. on both tests 

 for temperature and 60 on both tests for pulsations. 



The after period passes without any notable variation in normal 

 functions, the only change being the less frequent voiding of the urine 

 and a diminished volume. On April 22 the recorded temperature is 

 just under 98 F. and the pulsations 64 and 66, respectively, per 

 minute. The functions of the bowels are normal, and the times of 

 voiding the urine have fallen from ten per da} 7 during the preservative 

 period to six per day, and the volume of urine has diminished until it 

 is 1,180 cc. 



A stud} 7 of the above data reveals a very slight disturbing effect of 

 the preservative upon the body functions, apparently producing fre- 

 quent desire to urinate and causing a general feeling of malaise and 

 headache toward the end of the period. These symptoms disappear 

 when the boric acid ceases to appear in the urine in notable amounts. 

 These symptoms, however, ^re not of themselves entirely conclusive, 

 but there is also a slight loss of appetite during the preservative period, 

 which is not sufficiently marked to be recorded among the 'data.

The temperature and pulsations on March 20 are normal and all the 

 body functions are discharged as in ordinary good health. This con- 

 dition of affairs continues without any notable change during the whole
