period, the percentage rising to 106.4.' These data are directly 

 opposed to those obtained in the case of No. 2 for the same series of 

 observations. 



In the case of No. 6 we have the same series of phenomena exhibited 

 as respects the number of blood corpuscles as are shown in the case of 

 Nos. 1 and 3, namely, a gradual rise in the number of red corpuscles 

 during the series. Beginning with 5,000,000 in the fore period the 

 number rises to 5,668,000 in the preservative period, and to 5,780,000 

 in the after period. The hemoglobin, which is 91.6 per cent in the 

 fore period, falls to 82.4 per cent in the preservative period and rises 

 again to 102 per cent in the after period. 



Collecting all the data of Series V into one expression, we find that 

 the average number of corpuscles in the blood of all the subjects dur- 

 ing the fore period is 5,128,166, during the preservative period 

 5,571,000, and during the after period 6,042,200. These data seem to 

 indicate a tendency on the part of the preservative to increase the num- 

 ber of corpuscles in the blood. The hemoglobin numbers show an 

 average of 90.6 during the fore period, 87.6 during the preservative 

 period, and 102.4 during the after period. From these figures it 

 would appear that there is a tendency on the part of the preservative 

 to diminish the percentage of hemoglobin. 



Nos. 1, 3, and 5 are the only members of Series V who finished the 

 entire series. Considering these members only, the averages are as 

 given in Table XX.

 ering only Nos. 1, 3, and 5. 



The data concerning the blood must not be too literally- construed, 

 because of their contradictory nature in regard to individuals. The 

 final deduction can only be drawn that if this preservative affects the 

 number of corpuscles and the quantity of hemoglobin at all it does so 

 in a very irregular manner, differing in different individuals, and in 

 a way which can not be used as a basis of any definite conclusion.
