Section I. President's Address. 



Further work since Nottingham has shown a discrepancy between 

 Benedict's and DuBois's results. Benedict's results (Fig. i, 2) are incom- 

 patible with the variable combustion ratio, but are difficult to accept, because 

 on the alternative theory of the constant combustion ratio an evolution of 

 oxygen would be associated with an evolution of heat. DuBois's results 

 are compatible with both theories. 



Calculations on pp. 196, 197 of Cal. per litre of oxygen resulting from 

 conversion, at rest, after food and in muscular work also conform to both 

 theories so far as they relate to R.Qs. from about 0.72 to i. 



Those results of DuBois, where there is a large change of rectal tempera- 

 ture during the experiment, with a resulting large difference between 

 ' direct calorimetric ' and ' eliminated ' heat are uncertain and these form a 

 large proportion of the results outside the theoretical limits for Oo and 

 Cal. in Fig. 3, and also account for the apparent similarity of the results of 

 DuBois and Benedict mentioned on p. 191. Consequently there is no 

 absolute disproof of the variable combustion ratio ; but the constancy of 

 the CO2 over the range of quotients among other things makes the constant 

 combustion ratio more probable and basal metabolism is still best defined 

 and measured by the CO2 alone as indicated on p. 200 and the other deduc- 

 tions from p. 200 onwards stand. It is hoped that a final discussion of this 

 subject will appear in the Guy's Hospital Reports.
