of work in the amount of oxygen consumed to perform smaller 

 amounts of work than it did for a larger amount. Thus, per 100 

 kg. m. of work W. K. required 316 c. c. of oxygen above the standing 

 requirement when 200 kg. m. of work were performed per minute and 

 but 220 c. c. when 900 kg. m. of work were performed. That is, if
