it suitable to bring them ail together in one table, becaiise 

 différences can only be traced when looking at spécial 

 groups, and dividing thèse sufficiently under différent 

 lieadings. 



I hâve therefore selected from the tables in the appendix 

 ail reaction-times relating to cases, where 40 — 60 "/o were 

 curved (the cases, where the stimulation-time was nearly 

 equal to the presentation-time) and those, where 90 — 100 7o 

 were curved (the cases, where the stimulation-time was 

 sufficient to make ail seedlings curve). For thèse two 

 groups I calculated the average reaction -time at each 

 température and the values obtained in this way are set 

 down in the following table. 



Summary of reaction-times. 



d) Tlic cx|icrimcnts where the stimulation-time exccedcd 50 min. 

 are left ont of considération.
