BORIC ACID AND BORAX. 157 



tendency of the boric acid to diminish the elimination of nitrogen in 

 the urine. In the' summary for Nos. 7, 10, and 12, however, the 

 opposite tendency is shown. 



PHOSPHORIC ACID. 



The percentage of phosphoric acid eliminated in the case of No. 1 

 in the fore period is 58.4, in the preservative period, 58.8. In the case 

 of No. 2 the percentage eliminated in the fore period is 58.4, and in 

 the preservative period 61, a decided increase. For No. 3 the figures 

 are as follows: Fore period, 57.4; for the first and third subperiods, 

 57.8 (subject not in the second subperiod). No. 4 shows in the fore 

 period an elimination of 53.7 per cent, and in the preservative period 

 61.6 per cent, a very marked increase. In the case of No. 5 the per- 

 centage in the fore period is 57.1, in the preservative period 59.2, 

 again showing an increase. For No. 6 the fore period shows 50 per 

 cent of elimination, while the preservative period shows 65.5 per cent, 

 the largest increase noted. The summary for phosphoric acid shows 

 the following figures, considering only Nos. 7 aim 0: During the fore 

 period the per cent eliminated in the urine is 55.8, while in the pre- 

 servative period it is 60.4 per cent. This marked increase is undoubt- 

 edly due in part to the fact that all the members of this series were ill 

 with the grippe. 



SEEIES III. 



NITROGEN. 



The highest percentage of nitrogen eliminated in the urine in the 

 fore period is 94.2, the lowest is 78.3, and the mean for the 4 men 

 who finished the series is 86.6. In the preservative period the highest 

 percentage is 104.6, while the lowest is 81.1, and the mean for the 4 

 men is 87.3. In the after period the highest percentage is 85, the 

 lowest is 69.9, and the mean is 76.2. These figures indicate a slight 

 increase in the preservative period and a marked decrease in the after 

 period. 



PHOSPHORIC ACID. 



The highest percentage of phosphoric acid eliminated in the fore 

 period of Series III is 64, the lowest is 52.8, while the mean for the 4 

 men who completed the series is 59.5. In the preservative period the 

 highest elimination is 78.2 par cent, the lowest is 59.8, and the mean 

 is 68.2. In the after period the highest is 55.6 per cent, the lowest 

 48.8, and the mean 52.6. These figures show a marked tendency 

 toward an increased excretion of phosphoric acid in the urine during 

 the preservative period, followed by a decided decrease during the 

 after period.
