MILAN 

 DISCUSSION 



ADAMS; Would your metabolic rates measured in the bath 

 calorimeter compare with those measured under basal conditions? 



MILAN: I would say they would be about the same. 



HANNON: Were your basal metabolic rates measured under bed 

 rest conditions? 



MILAN: Yes, and I think, as pointed out by Henderson in 1926, 

 that there is a relationship between basal metabolic activity and 

 the circulation. Thus,if you have a slightly higher basal metabolism, 

 the energy flux is somewhat different, since if you subscribe to the 

 view of Hardy (1961) the hypothalamus regulates for temperature, 

 not energy flux. 



KLEIBER: I notice that there is a discrepancy from data pub- 

 lished by Swift,* who reported that his college students began shiver- 

 ing when their skin temperatures went down to 90 F. But now the 

 newer data seem to indicate that practically all human beings have 

 much higher skin temperatures at a critical level than the level at 

 which the metabolic temperature regulation starts. Is there an ans- 

 wer to this discrepancy? 



MILAN; I do not know. 



ADAMS; I might offer one suggestion; the method of taking the 

 average skin temperature makes quite adifference, if this measure- 

 ment was calculated in such a way as to give proportionalities to 

 each site different from conventional standards.
