In a further series of experiments, blood with added sugar was 

 subjected to the influence of a current of different gases. I was 

 desirous of ascertaining if oxygen promoted the ^disappearance of sugar, 

 and counterpart observations were made with carbonic acid and hydro- 

 gen. The results obtained afford no evidence of any chemical action 

 being exerted. Whatever slight effect occurred, I think, may be 

 assumed to have arisen from increased molecular action excited by the 

 transit of the eras.
