record. It will thus be seen that the latent period decreases 

 with rising temperature. 



The following table gives the results of several experi- 

 ments on the effect of temperature on the latent period : — 



Table III. — Effect of Temperature on the Latent Period. 



Summary 



Alternating electric shocks of moderate intensity induce 

 simultaneous excitation throughout the interposed tract. 



Latent period is in general shorter under stronger 

 intensity of stimulus. There is no further variation above 

 a maximal. 



In the optimum condition of the plant the latent period 

 is the same for feeble and strong stimulus. 



Fatigue prolongs the latent period. 



The latent period is shortened by a rise of temperature.
