126 INFLUENCE OF FOOD PKESERV ATIVES ON HEALTH. 



4,380,000 in the fore period, to 5,330,000 in the preservative period, 

 and to 5,695,000 in the after period. The hemoglobin reading at the 

 same time falls from 102.6 to 99.2 in the preservative period, and rises 

 again to 108.1 in the after period. 



In the case of No. 2 there is a decided decrease in the blood corpus- 

 cles during the preservative period, falling from 6,352,000 to 5,352,000, 

 and rising again to 6,248,000 at the end of the after period. The hemo- 

 globin also shows the same remarkable variations, falling from 96.8 

 in the fore period to 71 in the preservative period, and rising to 89.8 

 in the after period. In this instance it appears that under the admin- 

 istration of the preservative both the number of corpuscles and the 

 hemoglobin were diminished. 



In the case of No. 3, we have again the same series of phenomena 

 as were exhibited in No. 1, as to the number of corpuscles, which rose 

 from 5,450,000 in the fore period to 6,040,000 in the preservative 

 period, and again to 6,724,000 in the after period. There is also a 

 progressive increase in the amount of hemoglobin, which rises from 

 98 per cent in the fore period to 102 in the preservative period, 

 and to 105.9 in the after period. Both No. 1 and No. 3 show a con- 

 tinuous improvement in the character of the blood from the beginning 

 of the fore period to the end of the after period, and the administra- 

 tion of the preservative does not appear to have affected one way or 

 the other this progressive improvement. 



In the case of No. 4 the data are not complete, the subject having 

 withdrawn from the class and left the cit} T at the end of the preserva- 

 tive period. The number of corpuscles in the blood in his case slightly 

 decreases during the administration of the borax, but the percentage 

 of hemoglobin rises. This percentage, however, is so low, namely, 

 57.2, for the fore period that it should be accepted with some degree 

 of doubt, although the two observers agreed closely in their estimate 

 of it, the one having estimated the hemoglobin at 56.4 and the other 

 at 58.1. 



In the case of No. 5 it should be noted that there is also a change in 

 the personnel, No. 5 of the first series having been by reason of ill- 

 ness withdrawn from observation and placed on a special table, his 

 place having been taken by a much larger man. This subject, how- 

 ever, was markedly anemic as respects the number of red corpuscles 

 in the fore and after periods. The administration of the preservative 

 appeared to increase very markedly the number of red corpuscles, 

 which rise from 4,886,000 in the fore period to 6,344,000 in the pre- 

 servative period, falling again to 5,764,000 in the after period. The 

 percentage of hemoglobin, however, is not changed from the fore 

 period to the preservative period, remaining 97.5 in each case. There 

 is, however, a very decided increase in hemoglobin during the after
