BOEIC ACID AND BORAX. 



In the second preservative subperiod, extending from December 27 

 to December 30, inclusive, the average percentage eliminated is 87.6. 

 The highest is found in the case of No. 6, namely, 93.9, and the lowest 

 in No. 3, 81.9. 



In the third subperiod the average percentage of nitrogen elimi- 

 nated is 92.6. The highest percentage eliminated is found in the case 

 of No. 6, namely, 127.5, and the lowest in No. 2, 81. During this 

 period the elimination of nitrogen by No. 6 is very marked, indeed. 



For the entire preservative period, extending from December 22 to 

 January 3, inclusive, the average percentage of nitrogen eliminated is 

 91.8. The highest amount is again found in the case of No. 6, namely, 

 107.6, and the lowest in that of No. 3, 88.1. 



For the after period, extending from January 4 to January 13, 

 inclusive, the average elimination of nitrogen is 89.8 per cent. The 

 highest percentage is found in the case of No. 6, namely, 93.5, and the 

 lowest in No. 3, 82.7. 



The above data show a marked tendency to an increased elimination 

 of nitrogen during the administration of the boric acid. This is mani- 

 fested particularly in the case of No. 6, where the amount of nitrogen 

 lost is excessively large. In the case of No. 2 there is but little effect 

 produced, showing a marked toleration of the influence of borax in 

 this particular instance. The same is true of No. 5, practically no 

 effect upon the elimination of the nitrogen being manifested. 



SERIES II. 



The data for Series II are extremely imperfect by reason of the ill- 

 ness of Nos. 8, 9, 11, and 12 during the whole period, and the illness 

 of the whole number under observation during the after period. The 

 data of Nos. 7 and 10 are interesting but can not be regarded as very 

 conclusive. 



During the fore period the average daily percentage of nitrogen elimi- 

 nated by the two under observation is 89.8. During the first preserva- 

 tive subperiod it rises to 90.9, during the second to 86.7; for the first 

 and second subperiods it is 88.5; during the third subperiod the per- 

 centage rises to 90.1, and for the entire preservative period it is 89.1. 

 In the case of No. 7 the percentage of nitrogen eliminated is dimin- 

 ished, in the case of No. 10, increased. 



SERIES III. 



In this series the percentage of nitrogen eliminated during the fore 

 period is high, namely, 95.3. During the first preservative subperiod 

 the percentage eliminated is slightly decreased, namely, to 94.6. Dur- 

 ing the second subperiod it falls to 91.6. During the third subperiod 

 there is a very decided increase in the percentage eliminated, rising 

 to 102. 6. The average for the three subperiods is 96. During the after
