After laburious trials B, r and ^o were found from the plotted 

 curve of No. 37 (Plate XI., Fig. 1). As the breadth of the 

 stimulus, we took the interval Ijetween its beginning and the 

 instant of abrupt decrease of the current. Though our oscillo- 

 graph would not give a true picture for such a quick change of 

 current as our stimulus, it does not influence the value of the 

 stimulation-breadth taken as above. The result of the experiment 

 and the corresponding calculated values are given in the next 

 table, and represented graphically in Plate XL, Fig. 1.

 Temperature of the organ: llO'C. 



Resistance of the organ: 130 ohms. 



Formula used in calculation: // = 34 x (I -10-'-'''-^'- ■'■'>) 



As we see in the table and in the figure, the agreement of the 

 observed with the calculated values is very satisfactory. 



Oscillogram No. 58 (Plate XVII.) is an example in which 

 the breadths of the stimuli Avere too large, so that the heights of 

 tlie discharges showed a nearly constant value. In this oscillo- 

 gram, it may be seen that the height of the discharge never 

 becomes smaller with the increasing stimulation-breadth, even
