524 oxygen context of blood in pneumonic influenza. 



Summary. 



Samples of venous blood from eases of pneumonic influenza 

 showed no indication of decreased oxygen capacity nor of de- 

 ficient oxygenation . 



The concentration of hydrogen ion produced by the addition 

 of a measured quantity of acid showed no indication of acidosis: 

 the alkaline reserve was not reduced. 



In conclusion, I wish to express my indebtedness to Professor 

 Sir Thomas Anderson Stuart, in whose laboratory this work 

 was done, and to Dr. A. H. Tebbutt and Dr. Mona Kuss, 

 Honorary and Chief Resident Pathologists respectively of the. 

 Royal Prince Alfred Hospital, who placed at my disposal the 

 material upon which this investigation was carried out. I als-j 

 express my thanks for the assistance received from .Miss 

 Myrtle S . Bromley, M.A., in carrying out the eolorimet ric 

 estimations of haemoglobin.
