It is evident, from these results, that in diseased conditions the 
blood shows a considerable falling* off in peroxidase activity, or oxygem 
carrying power, as compared with that in normal conditions of health, 
and that in the majority of instances, at least, the peroxidase activity 
of blood is proportional to the percentage of hemoglobin. That such 
is the case may be seen by comparing the numbers given in the last 
column of our tables, in which the oxidizing power of the several 
specimens of blood are given in terms of normal blood (Amoss), the 
oxidizing power of w'hich has arbitrarily been made equal to 100, with 
the several percentages of hemoglobin which are to be found in 
another column of the tables. It will be observed that in 29 out of 
the IT specimens examined the numerical agreement between the oxi- 
dizing power of the blood and the percentage of hemoglobin is almost 
numerically exact, and that in the remaining cases it is sufficiently 
close to indicate a general agreement and correlation between oxidiz- 
ing power and hemoglobin content. 
The greatest differences in oxidizing power of the several samples 
of blood were brought out by allowing the oxidation to proceed for 
twenty-four hours. In most cases, however, if not in all, differences 
of a similar nature were shown after much shorter intervals. Thus, 
with the bloods composing series No. 1, which were examined on April 
22, the following results were obtained for several intervals, three 
of which were shorter than twenty-four hours. (See Table No. 1.)
