In the following series of experiments sugar was added to blood at 

 different periods after withdrawal. The results furnish the same kind 

 of evidence as that obtained through the previous observations. A 

 marked descent is noticeable in the reducing power until a certain 

 point is attained, after which but little change occurs, however long 

 the blood may be kept, and however putrid it may become. It seems, 

 therefore, as already suggested, that there is a reducing agent in the 

 blood which comports itself differently from sugar. If the reducing 

 action were due solely to sugar, it is not intelligible that there should 

 be a more or less sharp descent to a certain point, and then tha
