528 RHYTHMS IN PLANTS AND ANIMALS 



The fact, mentioned in the paper, that the first cycles after transi- 

 tion to lower temperature or after the application of a poison are even 

 longer than the normal ones found an explanation too: These treat- 

 ments make the oscillator drop to a lower level of energy, i.e., the 

 first relaxation is continuing for a longer time than the normal ones. 

 But the ensuing tensions are very small, thus causing shorter cycles. 

 This looks like a delay, followed by processes of compensation.
