i. e. either the repulsion P is a gradual and uniform effect, 

 or not. Fig. 3 shows a typical specimen of my readings. 



As the corrections V, E, 0, whatever their exact values 

 may be, do surely vary in the same way on incre;

current, i. e. they as well as their derivatives are both con- 

 tinuous functions of I, the " Knees " remarked on graph ,3 

 must remain after allowing for the corrections V, E, 0, 

 and consequently they are to be attributed to the true 

 repulsion P. 



If the explanation of P as a recoil effect by the departure 

 of carbon ions or molecules is accepted, the different traits of 

 the curves a or P are easily to be explained (S., p. 86) by- 

 assuming that when the current exceeds a certain value 

 oreater particles are also expelled from the craters.
