THE STANDARD METABOLISM OF THE ORGANISM 61 



constant weight to a constant height a variable number (N) of times 

 during a period of constant length (one hour) the metabolism, measured 

 by the output of carbon dioxide, could be accurately expressed by the 

 formula 



[COJ = N/. + q 



in which q is the standard metabolism and/ a constant, the metabolism 

 corresponding to lifting the weight once. 



Johansson and Koraen [1902] found further that when such work 

 was performed after the intake of varied amounts of food both influences 

 produced independent increases in metabolism which were additional 

 in character (see also Johansson [1908]).
