As a general thing the numbers for the direct oxidizing power of 
these several specimens of blood in terms of normal blood (Amoss, 
equal to 100) are somewhat higher than the corresponding numbers 
for the percentages of hemoglobin. This is true in twelve out of 
the fifteen cases studied. 
On account of the scarcity of clinical material we have not yet bee a 
able to subject this method to the rigorous test which is required before 
we shall be able to say whether such examinations as those herein 
described will have any practical value as aid to diagnosis. From 
the comparatively few cases, however, that we have thus far been 
able to collect there is every indication that such will prove to be tin- 
case. We propose, therefore, to extend these observations as rapidly 
as the necessary clinical material can be obtained and at the same time 
we shall endeavor to perfect and simplify the methods above described 
for determining the activity of the blood as a carrier of oxygen.
