HUDSON 



HART: Yes. 



HUDSON: No, I just did it on the basis of oxygen consumption. 



HART: You made the point that it was very low. I was won- 

 dering if this was in relation to body size. 



HUDSON: This is in relationship to body size. It is using the 

 equation from Brody in assuming that one cc of oxygen consumed 

 releases 4.8 Calories. 



PROSSER: Does this metabolism fall below the standard 

 curve? 



HUDSON; Yes. It falls about 66% below the standard curve. 



IRVING'. What does torpor mean in the dictionary? Does it 

 not mean a decline in brightness? I am still interested in the nap- 

 ping state. I was thinking there might be some other observation 

 that you could make other than whether the Poor-will recognized 

 you or not at the ther mo- neutral zone. 



WEST: Any way to test his reaction? 



IRVING: To show whether he was alert or not, or whether he 

 was taking a nap. 



HUDSON: Well, they will feed. I know that the animal is not 

 in a torpid state at what we call thermo-neutrality because he 

 will feed quite regularly. Now, if you force feed him when he is 

 torpid, he will die, apparently because of the decomposition of 

 food in the gut under those situations, and yet when they are not 

 torpid they can be fed successfully. Of course a torpid animal 

 will have his eyes closed. 



IRVING: But in the the rmo- neutral state, they feed and eye 

 reflexes are apparent, seem to be perfectly normal? 



HUDSON: Yes, perfectly normal.
