Change of the toxicity with the time of 6 C. 



Tab. 16. 



In the present case K was put 0, 104 expressed 

 by the above indicated arbitrary unit for the amount 

 of toxin, the unit of time was 1 minute. 



When the observations at 24.5 are treated in the same 

 manner, the following results are obtained. 



A x varying between 32,8 and 33,9 being relatively 

 great, ^^ becomes so small a figure, that it without 

 recognizable error can be considered as constant in all 

 four series. It follows from this, that all values of x t 

 must also be almost constant; the same applies to all
