Zuntz and Hagemann regard the lowest of these values, obtained on an 

 exclusive hay ration, as representing the basal katabolism of the horse and 

 regard the higher results as due to a stimulation of the metabolism in 

 periods of light feeding or of low temperature for the sake of heat pro- 

 duction — i. e., to a "chemical" regulation of the body temperature.
