522 INFLUENCE OF FOOD PRESEKVATIVES ON HEALTH. 



after period, a very marked diminution of the white corpuscles, and a 

 slight fading of the blood. 



While Nos. 9 and 10 are excluded from the summary for the rea- 

 sons already stated, the individual data may be considered. In the 

 case of No. 9 the red corpuscles decreased and the white corpuscles 

 increased in the preservative period, while both increased in the after 

 period. The color of the blood slightly increased in the preservative 

 period, but diminished very decidedly in the after period. 



In the case of No. 10 the red corpuscles decreased, the white cor- 

 puscles increased, and the color increased in the preservative period. 

 In the after period the red corpuscles again decreased, but very 

 slightly, the white corpuscles continued to increase, and the color of 

 the blood faded. 



No. 11 showed an increase in the number of red corpuscles during 

 the administration of the preservative, an increase in the white cor- 

 puscles, and a very slight increase in the intensity of the color of the 

 blood. There was a decrease in the number of red corpuscles in the 

 after period, a slight increase in the number of white corpuscles, and 

 a very slight increase in the intensity of color. 



No. 12 showed a considerable increase in the number of red corpus- 

 cles, a decrease in the number of white corpuscles, and a marked 

 increase in the intensity of color during the administration of the pre- 

 servative. During the after period the number of red corpuscles 

 diminished, the number of white corpuscles increased, and the inten- 

 sity of color was notably diminished. 



The summary of the number of corpuscles and the percentage of 

 hemoglobin in the blood for the nine men, compared throughout the 

 series, shows that the average number of red corpuscles for the fore 

 period is 5,690,000; for the preservative period, 5,900,938; for the 

 after period, 5,450,444. The number of white corpuscles in the fore 

 period is 10,609, in the preservative period, 10,714, and in the after 

 period, 9,836. The intensity of color, measured by the hemoglobin, 

 diminished regularly from the fore to the after period, l^eing repre- 

 sented by 106.1 in the fore period, 104.7 in the preservative period, 

 and 103.3 in the after period. There is an apparent tendency on the 

 part of the preservative to increase the number of the red and the 

 white corpuscles in the blood and at the same time to slightly diminish 

 the intensity of the color. During the after period the number of 

 both the red and the white corpuscles decreases and at the same time 

 there is still another slight decrease in the intensity of the color.
