[Apr. 3, 



That there appears to exist a reducing snbstance besides sugar in 

 the blood which is of a sufficiently stable character to resist the effects 

 of advanced putrefaction. Expressed as sugar, it amounts to from 

 •200 to '300 per 1,000. These figures, therefore, would appear to 

 require to be deducted from those which have been given as repre- 

 senting the amount of sugar present in the blood. 



That the passage of a current of oxygen through the blood does not 

 exert any appreciable effect in the direction of oxidation of the sugar.
