would expect that the values obtained on women would compare more exactly 

 per kilogram of body-weight with those obtained on fat men and an examination 

 of table 98 shows us that the group of fat men do exhibit a low heat production 

 on the average, although both the carbon-dioxide excretion and oxygen con- 

 sumption are somewhat greater than with the women. 



These results are more in accord with the results of Sonden and Tigerstedt 1 

 which showed a marked difference between men and women, and are at variance 

 with the results of Magnus-Levy and Falk, 2 who do not find the differences 

 appreciable. Furthermore, the criticism raised with regard to the experiments 

 of Sonden and Tigerstedt that the women were more quiet as a rule than the 

 men with whom they were compared hardly applies here, for in all instances the 

 persons remained quietly seated in the chair inside the chamber. It is obviously

 hours in rest experiments.

 and heat during waking hours.
