SERIES VII. 

 INDIVIDUAL DATA. 



In Table XIII are given the numbers of red and white corpuscles 

 per cubic millimeter and the percentage of hemogloblin in the blood, 

 calculated according to the methods pursued in the previous experi- 

 ments. A column giving the color index has been added to the 

 table, which expresses the change in the relation between the red 

 blood cells and the hemoglobin. 



In the case of No. 1 it is seen that the number of red corpuscles is 

 increased and the number of white corpuscles decreased during the 

 administration of the preservative. The hemoglobin is also decreased. 



a These examinations were made by B. J. Howard, chief of the microchemical
